Description

Reflective cap that improves illuminance of light

The present invention relates to a reflective cap that improves the illuminance of the light, and more particularly, to improve the illuminance of the light emitted from the light through the reflective cap, as well as to use by inserting the reflective cap to the lamp of the existing light. The present invention relates to a reflective cap that improves the illuminance of economical light that maximizes the range.

Common fluorescent lamps illuminate the installed space in offices, factories, and homes.

In the case of such fluorescent lamps, the amount of illuminance emitted is determined, and the number of fluorescent lamps to be installed is determined according to the area of the space to be installed. When the fluorescent lamp is installed in a large space, a plurality of fluorescent lamps are required. Consumed.

In order to solve this problem, techniques have been developed to improve the illuminance emitted from one fluorescent lamp to reduce the number of fluorescent lamps installed in a predetermined space or to obtain higher illuminance even if the same number of fluorescent lamps are installed. .

For example, "Fluorescent lamp reflector" is disclosed in Korean Utility Model Publication No. 20-0156365 (registered June 12, 1999).

The present invention relates to a fluorescent lamp reflector which improves the reflection efficiency of light emitted from a fluorescent lamp through the configuration of the first reflector and the second reflector, thereby improving the brightness of the fluorescent lamp.

However, this technology can improve the brightness of the fluorescent light to some extent by reflecting light emitted in a direction opposite to the direction in which the fluorescent light shines through the reflector, but in terms of efficiency of improving the light brightness through the reflector, The problem is that there are limitations.

In addition, Korean Utility Model Publication No. 20-0179621 (registered on February 11, 2000) discloses a high efficiency fluorescent lamp reflector.

The present invention relates to a high efficiency fluorescent lamp reflector which maintains a brighter illumination by increasing the reflection efficiency by having a large radius curved surface extending from the proximal position of the fluorescent lamp to the outside.

However, this technology can be expected to improve the illuminance to some extent to improve the illuminance by reflecting the light emitted from the fluorescent lamp through the reflector, but this also has a problem that can not be expected to greatly improve the illuminance of the fluorescent lamp through the reflector.

In the case of the prior art mentioned above, there is a problem in that the light emitted from the fluorescent light is reflected through the inclined plane of the reflector to improve the illuminance. Therefore, the technology capable of improving the illuminance of the fluorescent light through the reflector is higher. This was developed.

For example, Korean Patent Laid-Open Publication No. 10-2008-0065951 (published on July 15, 2008) discloses a "fluorescent lamp apparatus having improved reflection efficiency by expanding a reflecting surface."

This is to form the entire surface or a certain portion of the surface of the fluorescent lamp body in the form of zigzag irregularities, but to form a large number of intaglio or embossed embossing on each irregular surface to increase the diffuse reflectance, and also to reflect the reflection surface inside the fluorescent lamp body The present invention relates to a fluorescent lamp having improved reflection efficiency by installing a reflection shade in the form of zigzag irregularities, and forming a plurality of intaglio or embossing on each of the irregularities of each reflection shade to increase diffuse reflectance.

However, in the case of this technique, by forming a plurality of intaglio or embossing on each irregular surface of the reflector, it is possible to improve the illuminance of the fluorescent light to some extent compared to the above-mentioned prior art, but it is possible to improve the illuminance of the fluorescent light through only the reflector. There is still a problem with its limitations.

All of the prior art techniques for improving the illuminance of fluorescent light using the reflector mentioned above have their limitations in improving the illuminance of the fluorescent light through the reflector only.

In addition, the reflection shade for improving the illuminance of the fluorescent lamp has a structure that is integrally formed with the fluorescent lamp main body, so that different fluorescent lamp main bodies (for example, a main body such as hanging, a main body such as a wall, and a buried main body, etc.) There is a problem that cannot be used.

Therefore, there is a demand for developing an economical reflector that can be easily installed in various kinds of lamps (hanging lamps, wall lamps, buried lamps, etc.) as well as improving illuminance of fluorescent lamps.

Therefore, an object of the present invention is to improve the illuminance of the light, as well as to be able to use the reflection cap to the existing lamps of various lamps regardless of the type of light, thereby maximizing the utilization range of the reflection cap and the irradiation angle of light It is to provide a reflective cap to improve the illumination of the adjustable light.

In order to achieve the above object of the present invention, the present invention provides a reflective cap for improving the illuminance of the light including a sheet fitted to the lamp of the light to improve the illuminance of the light.

The reflective cap is fitted to the lamp of the lamp to spread the light emitted from the lamp, and the front and rear ends of the front sheet and both ends are attached to each other to provide a space for receiving the lamp, the light emitted from the lamp It includes a backsheet that diffuses or reflects.

When using a reflective cap to improve the illuminance of the light according to the present invention, as well as improving the illuminance, it can be used more easily fitted to the existing lamps of various lights can be expected economic effects.

In addition, the reflective cap may serve as a kind of lamp cover due to the structure that is used to be fitted to the lamp of the lamp. Accordingly, a certain shock absorbing effect can be expected in the event of a fall of a lamp or a lamp, and an effect of preventing an accident due to broken debris can be expected to some extent when the lamp is broken.

In addition, it is possible to adjust the irradiation angle of the light through the angle of the reflection cap fitted to the lamp of the light.

In addition, by improving the diffusion effect and illuminance of the light through the reflective cap, not only can reduce the number of lights used in a certain space, but also to reduce the power consumption through this can be expected to save energy. In addition, by reducing the power consumption can reduce the amount of CO ₂ generated during power generation can provide a reflective cap that improves the illuminance of the lamp that can help to reduce the environmental pollution. In addition, the reflective cap is made of a material that can be recycled to further reduce environmental pollution, it can provide a reflective cap that is economically beneficial.

In addition, by improving the light diffusion effect through the perforations, not only can prevent the existing light staining phenomenon, it is possible to slim the signboard lighting device, it can be expected to reduce the material cost by slimming.

Hereinafter, with reference to the drawings will be described in detail the reflection cap for improving the illuminance of the light according to an embodiment of the present invention.

The sheet consists of a front sheet 110 and a rear sheet 120, and the front sheet 110 and the rear sheet 120 are partially attached to each other.

The front sheet 110 may use a diffusion film that is inserted into the lamp 200 of the lamp and serves to diffuse and transmit the light emitted from the lamp 200.

The rear sheet 120 is attached to the front sheet 110 and a part of each other to provide a space in which the lamp 200 of the lamp can be accommodated, the front sheet to the light emitted from the lamp 200 of the lamp A reflective film reflecting in the (110) direction may be used.

If the reflective cap 100 can be fitted only to the lamp 200 of the lamp, the front sheet 110 and the rear sheet 120 may be attached to any portion, but preferably the front sheet 110 and the rear sheet. Both ends of the 120 are preferably attached to each other. Here, both ends 114 and 116 of the front sheet 110 and both ends 124 and 126 of the rear sheet 120 may be attached to each other, but any method may be used, but both ends of the front sheet 110 may be used. It is preferable to perform fusion welding by high frequency treatment in a state where both ends 124 and 126 of the back sheet 120 are contacted with the 114 and 116. Alternatively, the front sheet 110 and the rear sheet 120 may be compressed by using a metal member such as aluminum in a “⊂” shape instead of the high frequency treatment.

May be attached to each other to provide a space in which the lamp is accommodated, and may include a back sheet using a reflective film reflecting light emitted from the lamp.

More specifically, the front sheet 110 is inserted into the lamp 200 of the lamp, and along the longitudinal direction of the diffusion body portion 112 and the diffusion body portion 112 for transmitting the light emitted from the lamp 200. The first diffusion end 114 and the second diffusion end 116 may be formed to extend from both ends and contact the rear sheet 120. Here, the first diffusion end 114 and the second diffusion end 116 are formed to have the same or similar size as the first reflection end 124 and the second reflection end 126 which will be described later, as shown in FIG. Can be.

5 is a perspective view showing a reflecting cap for improving the illuminance of the light according to the second embodiment of the present invention, Figure 6 is a perspective view showing a reflecting cap for improving the illuminance of the light according to the third embodiment of the present invention.

Referring to Figure 5, the sheet is fitted to the lamp of the lamp and the front sheet 110 consisting of a perforated reflective film for diffusing the light emitted from the lamp, and both ends and the both ends of the front sheet attached to the lamp It provides a space that is accommodated, and is configured to include a back sheet 120 using a reflective film for reflecting light emitted from the lamp.

Referring to FIG. 6, as another embodiment, both the front sheet 110 and the rear sheet 120 may be formed of the perforated reflective film, and light is uniformly diffracted and diffused through the perforated reflective film. As a result, uniform illuminance can be exhibited in a wide range.

In more detail, the front sheet 110 may be made of a reflective film of the same opaque material as the rear sheet 120 to improve the reflectance of light using the stretched synthetic resin material. At this time, the front sheet 110 and the rear sheet 120 is preferably using a polyester, PET or PP.

Formed only on the surface of the front sheet 110 (see FIG. 5, the second embodiment) or on the surface of the front sheet 110 and the rear sheet 120 (see FIG. 6, the third embodiment) The number of 130 may be differently formed according to a design purpose within a range in which uniform illuminance of light is diffused by diffusing light emitted from the lamp 200.

Specifically, in the case of the protruding signage, the advertising board of the bus stop, and the signage plate, which require the light to be uniformly spread on both sides of the lamp, it is preferable to use a form in which both of the sheets shown in FIG. 6 are perforated.

However, since a separate processing process for punching the reflective film is required and costly, diffusion performance is improved instead of the perforated reflective film in order to spread the light uniformly to both the front and the rear as in the third embodiment. If a good diffusion film is used as a double-sided sheet, no separate perforation is required. In this case, a PET film may be used as the diffusion film having excellent diffusion performance, and specifically, SKC CH283 (trade name) may be used.

When the diffusion film having excellent diffusion performance is used, light is uniformly diffused on both sides of the protruding signboard, the advertising board of the bus stop, and the signboard, so that a small number of fluorescent lamps may be used, thereby saving energy and diarrhea. Even if the fluorescent lamp is damaged, the fluorescent lamp stain is not generated due to the excellent diffusion performance.

7 is a perspective view showing a reflection cap for improving the illuminance of the lamp according to a fourth embodiment of the present invention.

Referring to FIG. 7, the reflective cap 100 may further include a photoluminescent part formed at a portion where the front sheet 110 and the rear sheet 120 are attached to each other.

The photoluminescent unit 140 is described to be positioned at a portion where the front sheet 110 and the rear sheet 120 are attached to each other, but the position of the photoluminescent unit 140 may vary depending on the design purpose.

The photoluminescent unit 140 is coated with a phosphorescent pigment that absorbs and emits light energy. The phosphorescent pigment may be manufactured by Nemoto, Japan.

The photoluminescent unit 140 may serve as a road guide in the dark through the light emitted by itself in the event of a power failure or fire as the photoluminescent pigment is applied. That is, when the light emitting unit 140 is used for a lamp provided inside the building, the emergency or emergency stairs can be guided to a person moving in the building during an accident such as a power failure, and in an underground facility such as an underground parking lot or an underground mall. In the event of an accident, it can act as a lifeline by indicating the direction of movement.

The photoluminescent pigment belongs to a kind of luminous pigment as an inorganic pigment. The phosphorescent pigment has the same basic properties as the phosphor, but unlike the phosphor has a property that the energy caused by the previously received light energy is emitted to the light energy again for a certain time, even when the light is blocked.

These photoluminescent pigments have significantly improved brightness and afterglow time compared to conventional luminous materials, and are durable, so that absorption and emission of light are continuously performed, and their performance is not degraded under any conditions.

The energy sources that can be absorbed are natural light and incandescent lamps used in daily life such as sunlight, mercury lamps, electric lamps and incandescent lamps. Appears.

In other words, the light having a higher energy in the visible light region, that is, the light having a wavelength around 400 nm increases the energy absorption rate. This is the result that the absorption region of the photoluminescent pigment is most distributed at 200 to 450nm. This problem does not significantly affect the performance of the photoluminescent pigment, since most of the commonly used indoor light using a lot of lights.

In addition, the luminous pigment has a difference in the luminous efficiency according to the light intensity. In other words, a strong light such as sunlight is enough absorption in a short time, but a relatively weak incandescent lamp consumes more time.

In a room with a normal lamp (less than 200 lux), about 30 minutes is enough to perform.

In addition, since it does not contain heavy metals and radioactive substances that affect the human body and ecosystem, the stability is also excellent.

As the photoluminescent pigment applied to the photoluminescent unit 140, it is preferable to use a silk printing method. Silk printing is a printing method that is mainly used only on flat or circular curved surfaces by printing with ink flowing on the uncoated portion of the mesh.

On the other hand, when the reflective cap 100 is formed in a structure in which one side or both sides are open, the finishing portion (not shown) to selectively cover one side or both sides of the lamp 200 is inserted into the interior H) may be further included. At this time, the finishing part may be formed in any shape if it covers both sides of the reflective cap 100 so as to cover both sides of the lamp 200, but preferably inserted into the outer peripheral surface of one side of the reflective cap 100 It may be formed in a shape that can cover the both sides extending from the structure or the front sheet or the back sheet that can be. In particular, the finishing portion may be formed with a through hole so that the terminal pin (not shown) of the lamp penetrates inside one side thereof.

FIG. 8 is a perspective view illustrating a reflecting cap for improving illuminance of a light according to a fifth embodiment of the present invention, and FIG. 9 is a cross-sectional view illustrating an electric sign using a reflecting cap according to a fifth embodiment of the present invention.

8 and 9, the reflective cap according to the fifth embodiment of the present invention includes a front sheet 110 and a rear sheet 120.

The front sheet 110 may use a diffusion film, the length of the diffusion body portion 112 and the diffusion body portion 112 is inserted into the lamp 200 of the lamp to transmit the light emitted from the lamp 200. The first diffusion end 114 and the second diffusion end 116 may be formed to extend from both ends in a direction to contact the backsheet 120. Here, the first diffusion end 114 and the second diffusion end 116 is formed to have a width smaller than the first reflection end 124 and the second reflection end 126 as shown in FIG.

 The rear sheet 120 may use a reflective film and extend from both ends along a length direction of the reflective body portion 122 and the reflective body portion 122 for reflecting light emitted from the lamp 200. The first reflective end 124 and the second reflective end 126 may be in contact with the front sheet 110. Here, the first reflective end 124 and the second reflective end 126 are formed to have a wider width than the first diffusion end 114 and the second diffusion end 116 as shown in FIG.

As a specific aspect, the reflective cap 100 according to the present invention is the first diffusion end 114 and the first diffusion end 114, as shown in Figure 9 for use in a signboard 300, preferably a billboard attached to the outer wall of the building, etc. The second diffusion end 116 is formed to have a width smaller than the first reflection end 124 and the second reflection end 126, and is attached to the first reflection body part 122 or the first reflection end 124 and the first reflection end 124. 2 may be attached to the reflective end 126. That is, although the light emitted from the lamp 200 by the panel constituting the sign 300 is not transmitted through all but only a part of the reflection, the reflective cap 100 diffuses the light through the diffusion body 112, the panel The light that is not transmitted by the light is reflected toward the front through the first reflective end 124 and the second reflective end 126 and passes through the panel. That is, when the reflective cap 100 according to the present invention is connected to the lamp provided inside the signboard, the overall illuminance of the signboard is improved.

As the above-mentioned diffusion film and the reflective film, it is preferable to use polyester terephthalate (PET) or polypropylene (PP).

The diffusion film is preferably manufactured to be transparent to transmit the light emitted from the lamp 200 of the lamp, the reflective film is preferably manufactured to be opaque.

Here, as the diffusion film which serves to diffuse the light emitted from the lamp 200 of the lamp, it is preferable to use a diffusion film containing PET, specifically HB3 (trade name) of DuPont It is good to use. Or by applying a color pigment to the transparent PET film as the diffusion film, depending on the type of pigments can be produced in red, yellow, blue, green, etc. can be used as lighting layout.

In addition, the reflective film that serves to reflect the light emitted from the lamp 200 of the lamp is manufactured to be opaque, to improve the reflectance of the light emitted from the lamp 200 of the lamp. The reflective film may be any material as long as it is a material capable of reflecting light emitted from the lamp 200 of the lamp, but in one embodiment, it is preferable to use a white polyester film having a reflectance of 96% or more. Specifically, it is recommended to use Reflectol (trade name), which is developed by SKC's SY70 (trade name) or JCI Corporation for the first time in the world, and has a total reflectance of 99% or more and a diffuse reflectance of 96% or more.

As another embodiment, the stretched synthetic resin material may be used as the reflective film that serves to reflect the light emitted from the lamp 200 of the lamp. In this case, the stretched synthetic resin material is preferably used to extend the crystalline synthetic resin material at a temperature below the crystallization temperature (Tc). The crystal regions of the reflector plate material before the stretching diffusely reflect the light, while the amorphous region transmits the light. Thus, when the translucent crystalline plastic before stretching is low-temperature drawn at or below the crystallization temperature, the amorphous regions are oriented, so that not only diffuse reflection occurs in the crystal region but also diffuse reflection occurs in the oriented amorphous region, thereby obtaining high reflectance.

For example, since the general crystallization temperature is 160.8 ° C. for PET, in the present invention, when the crystalline synthetic resin is drawn at a lower temperature than the crystallization temperature below the crystallization temperature, the amorphous region is oriented, thereby obtaining a sheet having improved reflectance.

Here, the crystalline synthetic resin material is polyethylene terephthalate (PET), polyethylene naphthalate (polyethylene 2,6-naphthalate: PEN), polybutylene terephthalate (PBT), polypropylene (polypropylene: PP, polyethylene (PE), high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE) and the like can be used.

In addition, the reflective film and the diffusion film used as the front sheet 110 or the rear sheet 120 of the reflective cap to improve the illuminance of the lamp according to the present embodiment is a film coated with a UV blocking coating or a UV blocking coating on the surface thereof. You can also use Here, the sunscreen coating may be a '3M' sunscreen coating. This is to prevent the skin from being damaged by the near ultraviolet rays emitted from the lamp 200.

In addition, the reflective film and the diffusion film used as the front sheet 110 or the rear sheet 120 of the reflective cap to improve the illuminance of the lamp according to the present embodiment antistatic to prevent the foreign matter is attached to the static electricity is generated Treated or antistatic films can also be used. Here, as the antistatic material, for example, unsaturated phosphonium sulfonate can be mentioned. In addition, any of the antistatic materials that can be antistatic may be used.

As such, as the light diffusing film, a diffusion film coated with an antistatic treatment and a barrier coating agent may be used, and in particular, it is preferable to use CH283 (trade name) of SKC.

In addition, the surface of the front sheet 100, the rear sheet 120, or both may be coated with a photocatalyst such as TiO ₂ for sterilization and purification of air. The photocatalyst may be activated by heat and ultraviolet rays generated from a lamp to purify the air.
