[ Light passing through the second surface 386 is reflected by the reflector 200 and is emitted to the lower portion of the housing 100.

That is, the light emitted from the first light emitting module 320a and the second light emitting module 320b passes through the first surface 383 of the optical cover 380 to illuminate the illumination area as direct light, The indirect light can be reflected to the illumination area through the reflection from the first surface 383 of the reflector 200 and the reflector 200. [ In this way, the illuminating device 1 can provide indirect light while providing direct light.

Some of the light emitted from the light source body is reflected by the first reflector 385 and the second reflector 387 disposed on the first surface 383 and then reflected by the reflectors 200a and 200b again, .

The first reflector 385 and / or the second reflector 387 are disposed on the first surface of the light source cover 380 to increase the amount of light reflected by the reflectors 200a and 200b to increase the ratio of indirect light .

On the other hand, the protective cover 360 can be disposed between the body portion and the optical cover 380. The protective cover 360 may protect the first light emitting module 320a and the second light emitting module 320b from moisture or the like that may flow into the light source unit 300. [

The protective cover 360 may also function as an optical member and may function to disperse the light emitted from the first and second light emitting modules 320a and 320b evenly.

The protective cover 360 and / or the optical cover 380 may include at least one of a lens, a diffusion sheet, and a phosphor luminescent film (PLF). The lens may include lenses having various shapes, such as a concave lens, a convex lens, and a condenser lens, depending on the design of the illumination device.

The diffusion sheet can evenly diffuse the light emitted from the plurality of light emitting diodes (312).

The photo-excitation film (PLF) may be a film containing a phosphor. The phosphor included in the photo-excitation film (PLF) is excited by the light emitted from the first light emitting module 320a and the second light emitting module 320b, so that the illumination device includes the first light emitting module 320a and the second light emitting module 320b. The first light emitted from the phosphor layer 320b and the second light excited by the phosphor are mixed to realize emotional illumination having various colors.

For example, when the first light emitting module 320a and the second light emitting module 320b emit blue light and the photo excitation film (PLF) includes a yellow phosphor excited by blue light, Light and yellow light are mixed to emit white light.

The protective cover 360 and / or the optical cover 380 can be easily replaced with any one of a lens, a diffusion sheet, and a photo-excitation film depending on the needs of the user.

5. Light source  (300) and [0034]  (110)

1) Coupling process

The light source unit 300 may be detachably coupled to the coupling member 110.

A first force F is applied to the first body 310a of the light source unit 300 and the connection member 340 disposed on the second body 310b so that the width between the connection members 340 is narrowed . At this time, the first force F may be opposite to the direction of the elastic force applied by the spring 370.

The light source unit 300 is inserted into the insertion groove 112 of the engaging member 110 and the light source unit 300 is inserted into the insertion groove 112 of the engaging member 110. [ .

The light source unit 300 is inserted into the insertion groove 112 of the coupling member 110 while applying the first force F to the coupling member 340. When the first force F is not applied after the coupling member 110 is inserted into the insertion groove 112, the gap of the coupling member 340 is further distanced by the elastic force, The engaging step 344 of the member 340 can be inserted into the third groove 113 formed in the inner surface of the insertion groove 112. [ Accordingly, the light source unit 300 can be coupled to the coupling member 110.

Since the spring 370 disposed between the coupling members 340 pushes the first body 310a and the second body 310b together after the light source unit 300 is coupled to the coupling member 110, The connecting member 340 can be more firmly coupled to the third groove 113.

In addition, uniform pressure is constantly applied to the contact surface between the connecting member 340 and the insertion groove 112 by the spring 370. Accordingly, the heat generated from the light source unit 300 can be conducted more efficiently through the contact surface of the coupling member 340 and the coupling member 110.

2) Separation process

When maintenance of the light source unit 300 is required, the light source unit 300 can be separated from the coupling member 110.

When the light source unit 300 is separated from the coupling member 110 by applying a first force F to the coupling member 340 so that the width between the coupling members 340 is reduced, (110).

[Arrangement example of heat dissipating structure]

As shown in FIG. 9A, the light source bodies 310a and 310b may extend from one surface to the other surface along the first axis 33. FIG. The light emitting modules 320a and 320b disposed on one side of the light source bodies 310a and 310b may have different degrees of heat concentration depending on their positions.

Fig. 38 shows the degree of concentration of heat when two light source bodies are disposed on the inner upper surface of the housing. Fig. 39 shows a light source body in which a radiating fin is disposed at a central portion.

As shown in FIG. 38, the heat generated by the use of the illumination device is concentrated in the light emitting module disposed at the center of the light source body. Since the performance of a light emitting device such as an LED chip is deteriorated by heat, the performance of the light emitting module disposed at the center of the light source body is easily deteriorated as compared with the light emitting module disposed at the side portion.

As a result, there is a difference in luminous intensity between the central portion and the side portion of the lighting apparatus, and the light uniformity of the lighting apparatus may be lowered.

In another embodiment, the heat dissipation structure may be disposed on the side of the light source body corresponding to the area where the first light emitting module is disposed.

On the other hand, the first heat dissipating structure may be disposed on the first region of the other surface or the side surface of the light source body, and the second heat dissipating structure may be disposed on at least a portion of the surfaces other than the first region. However, the arrangement density of the first heat-dissipating structure may be higher than the arrangement density of the second heat-dissipating structure.

In the first region where the first heat-dissipating structure having a high batch density is disposed, the heat dissipation is better than in the portion other than the first region where the second heat-dissipating structure having a low batch density is disposed.

The first heat-dissipating structure and the second heat-dissipating structure may be heat dissipating fins or through holes. The distance between the heat dissipating fins or the through holes of the first heat dissipating structure may be narrower than the distance between the heat dissipating fins or the through holes of the second heat dissipating structure.

According to the above-described configuration, the first light emitting module in the center portion where the generation of heat is concentrated and the second light emitting module in the side portion can emit light with a uniform light flux value.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Therefore, it should be understood that the above-described embodiments are illustrative and non-restrictive in all aspects, and that the scope of the present invention is defined by the appended claims rather than the foregoing description, And all changes or modifications derived from equivalents thereof should be construed as being included within the scope of the present invention.
