It is composed of a plurality of PCB assembly 160 and its protective cover 180 that is electrically connected to the top cover 150 to emit light.

The frame 110 includes at least a bottom portion 120, a front portion 130, and a side portion 140 so that light emitted from the PCB assembly 160 is emitted toward the bottom of the frame 110 and forward and sideways. It is provided. In the exemplary embodiment of the present invention, the bottom portion 120, the front portion 130, and the side portion 140 are formed at right angles to form a rectangular shape as a whole, but the bottom portion 120 and the front portion 130 In addition, the angle between the side portions 140 need not form a right angle, and may be inclined or curved depending on the lighting environment.

In addition, when the front part 130 having a relatively longer length than the side part 140 is perpendicular to the floor, the light is not reflected by the reflector 200 because the light is not concentrated on the floor even by the reflector 200. Assuming that it is reflected downward, the lower side of the front portion 130 is perpendicular to the front, but the upper side of the front portion 130 may be configured to be slightly inclined upward to correspond to the reflection shade 200. When the light is emitted upward in this way, the light reflected by the reflector 200 is reflected back to the bottom to generally reflect the lower portion of the frame 110.

The bottom portion 120, the front portion 130, and the side portion 140 of the frame 110 are provided with mounting grooves (no reference numerals) facing inwards, such that the PCB assembly 160 and the protective cover 180 are provided.

In addition, the side protection cover 144 is fixed to each of the frames 120, 130, and 140 using bolts, thereby protecting the PCB assemblies 122, 132, and 142 while simultaneously protecting each PCB assembly (122, 132, and 142). ) Function. Of course, the top portion 152 is provided on the top surface of the frame 110 on which the top cover 150 is mounted, and the top portion 152 is provided with a mounting groove for mounting.

A plurality of light emitting devices 190 are arranged in the PCB assembly 160 according to an illumination environment, and emit light when the electric drive signal is supplied from the top cover 150. Therefore, the light emitting device 190 is composed of a light emitting unit 192 that emits light and a pair of basic terminals 194 composed of a positive electrode (+) and a negative electrode (-) to supply electricity, and the implementation of the present invention. In the example, a light emitting diode (LED) is used. The LED is a semiconductor that converts electricity into light, and the response speed is faster than that of an incandescent lamp or a fluorescent lamp, and power is about 1/10 of that of a fluorescent lamp. In addition, the LED has a long life long enough to be used semi-permanently, does not generate a lot of heat when emitting light, it is a semiconductor that converts electricity directly to light has the advantage of higher efficiency than a fluorescent lamp.

The first inclined portion 210 inclines both in the front direction and in the side direction, and serves to reflect down the light emitted from the light emitting device 190.

The inclination angle α of the first inclined portion 210 is preferably formed within a range of 45 ° to 75 ° with respect to the vertical line. When the inclination angle α is within 45 °, light is collected in a narrow area. When the inclination angle α is 75 ° or more, only a small amount of light may be reflected even if the light does not reflect or reflects. The inclined portion may be formed in multiple stages for reflection and refraction of light. Therefore, the inclination angle β of the second inclined portion 220 is preferably formed in the range of 30 ° to 50 ° in consideration of the straightness of the light.

Although not necessarily, the above-described upper front part 130 corresponds to the first inclination part 210, the lower front part 130 corresponds to the second inclination part 220, and the upper front part. Since the inclination angle θ of 130 may not be larger than the first inclination angle α of the reflection shade 200, the inclination angle θ may not exceed 75 ° and is preferably determined within a range of 40 ° to 70 °.

On the other hand, the main lighting device 100, the front frame is formed longer than the side frame, the front frame is formed to a predetermined length, it is necessary to standardize the length for mass production and compatibility of parts.

In addition, the auxiliary frame 310 is formed by separating the auxiliary frame 310 into left and right auxiliary frames 312 and 314 to easily attach and detach the auxiliary frame 310 to the structural frame 110. Therefore, the assembly of the auxiliary lighting device 300 is as follows.

First, the mounting part 302 provided in one side auxiliary frame 312 is installed to correspond to the mounting groove of the side part 140 of the structural frame 110, and is fastened using a bolt. The other auxiliary frame 314 is installed to correspond to the one side auxiliary frame 312, each auxiliary PCB assembly 322, 332, 342 is installed in each seating groove, and each auxiliary protective cover 324, 334, 344 The bolting replaces the connection of the left and right auxiliary frames 312 and 314.

According to another embodiment of the present invention, as shown in FIG. 6, the auxiliary side part 340 of the auxiliary frame 310 having no seating part 302 in the auxiliary lighting device 300 has a constant inclination angle. Can be configured to achieve The inclination angle λ is preferably formed in the range of 40 ° to 70 ° similarly to the inclination angle θ of the main upper front part.
