Description

LED desk stand, suitable irradiation angle adjusting device {LED desk stand and apparatus for controling illustration angle}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk stand using a high brightness LED (LED) lamp, and more particularly, to an LED desk stand having a support of a weight balance method and an irradiation angle adjusting device suitable thereto.

A desk stand is a light that is placed on a desk and reads light with proper illuminance when reading a book or at work. The desk stand has the advantage of being able to increase concentration compared to a general lighting device installed on a ceiling. Crab is used a lot.

As such desk stands, various light sources and various designs are on the market.

Conventional desk stands required a multi-jointed support and a fastening device to fix the position by tightening each joint to maintain the lighting unit at any height and angle. As a result, to change the position of the light, it was troublesome to loosen the tightening device, set the position, and then tighten it again.

In addition, when the tightening device is stiff, there is a problem such as being damaged by excessive force, or to worry about such damage, take the inconvenience and use without changing the position.

On the other hand, as a light source of a conventional desk stand, a halogen, an incandescent lamp, a fluorescent lamp, or the like having a structure that emits light by flowing an electric current through the internal filament of the vacuum glass tube has been used. Since the light source has a property of radiating light in all directions, a conventional desk stand adopts a configuration to cover the light source or adjust a direction to be illuminated through a reflector. However, even when reflecting light through the reflector there is a problem that increases the eye fatigue because the concentration of light falls.

In addition, since this kind of light source consumes a lot of power, the conventional desk stand had to be powered from an AC power source. Accordingly, the conventional desk stand cannot be used while freely moving the desk stand because the conventional desk stand cannot be used in a place where there is no AC power source or a place that cannot be connected due to the limitation of the power line.

Even if you can easily change the light source height, position, and irradiation angle of the lighting device, and adjust the illuminance and color temperature easily, even on the same desk, you can minimize eye fatigue and concentrate on the work and learning. It can be improved to double and improve productivity.

Conventional desk stand also had a function to adjust the illuminance. However, since the illuminance control device of an incandescent lamp or a halogen lamp basically regulates the amount of current applied to the light source, that is, the amount of heat generated, there is a problem in that the color temperature is also changed with the illuminance. Accordingly, it is not easy to simultaneously satisfy the appropriate illuminance and color temperature in the environment for photography / video shooting.

Recently, various desk stands using high brightness light emitting diode (LED) lamps have been commercialized. The desk stand using the high-brightness LED lamp has advantages such as that the power consumption is 1/9 or more, and the life of the light source is semi-permanently longer than those of the conventional incandescent or fluorescent bulbs.

In addition, the LED desk stand has a problem that it is not possible to appropriately adjust the irradiation angle only by the existing reflector because the optical property has a good linearity.

However, these LED desk stands were nothing more than replacing the light source used in the existing desk stands with high brightness LED lamps. That is, desk lamps using LEDs currently on the market have a problem in that the illumination and temperature control characteristics of the LED lamps are not taken into account in illumination control.

The present invention has been made to solve at least some of the above problems and to provide a desk stand having a support structure that allows the user to freely and comfortably adjust the height, position and the like of the light source.

Another object of the present invention is to provide an irradiation angle adjusting device that can easily adjust the angle of illumination in a desk stand employing an LED lamp.

LED desk stand according to the present invention to achieve the above object is a first movable body, which is equipped with a first weight balance added to maintain a weight balance with the LED lighting unit at one end and the LED lighting unit at the other end, the first movable at one end The second movable body is pivotally connected to the center of gravity of the sieve in a clockwise or counterclockwise direction and is equipped with a second weight balancer on the other end to maintain the weight balance with the first movable body, and at one end of the second movable body. The center of gravity is rotatably connected in a clockwise or counterclockwise direction, the fixed support for supporting the first movable body and the second movable body, and the other end of the fixed support are fixed, and the first movable body and the second movable body are fixed. It characterized in that it comprises a lower support for supporting.

The irradiation angle adjusting device of the LED desk stand having the LED lighting unit according to the present invention for achieving the above another object constitutes a cylindrical lens disposed in the longitudinal direction of the LED lamp, the front and rear surfaces of the LED lighting unit and the cylindrical lens And a pair of support plates having a straight slit formed therein so that the screw means for fixing can be connected to one end and the other end of the cylindrical lens.

LED desk stand according to the present invention can be adjusted arbitrarily to adjust the irradiation angle of the light by adding an optical structure, the position of the light source can be changed freely, so that the concentration can be further improved to double the work / study ability You can.

In particular, in a desk stand using a light emitting diode as a light source, by adopting a center of gravity balance structure that also serves as a heat sink heat dissipation structure, it is possible to easily change the height and position of the light source, while maximizing its performance.

In particular, it is possible to double the efficiency of work and study by increasing the concentration by easily adjusting the illuminance, the color temperature, and the color of the light.

In addition, by adopting the rechargeable power source by using the characteristics of the light emitting diode, which has the advantage of low power consumption, the position of the desk stand is not limited to the location near the power outlet.
