Description

Flat lighting apparatus

The present invention relates to a flat panel lighting device.

In general, widely used lighting devices can be roughly divided into incandescent and fluorescent lamps, one of which is usually a spiral twist of a tungsten alloy to form a filament. So, when the filament is electricity, it generates a lot of heat, the temperature rises and the light is emitted.

In addition, the fluorescent lamp is a step further from the incandescent lamp by the filament heat generated as described above using electric discharge at high voltage. Fluorescent lamps contain a small amount of mercury vapor and argon gas for easy discharge, and then attach electrodes to both ends. When a high voltage is applied between the electrodes, discharge occurs and radiates light.

 However, in the case of the incandescent lamp as described above, there is a disadvantage that a lot of electricity is consumed when turned on for a long time. Therefore, it is not economical to use indoors such as buildings that need to be turned on for a long time, but it may be advantageous to use incandescent lamps in places such as bathrooms where frequent on / off cycles are frequently required.

 On the other hand, since the fluorescent lamp is not discharged properly when the end of life can be felt badly flickering. If it flickers badly when it is lit, the glow lamp has lost its function. If the edge of the fluorescent lamp turns black and the light flutters or flickers, the lamp has reached its end of life. Therefore, there is a serious disadvantage of eye fatigue.

 In recent years, LEDs (Light Emitting Diode Light Emitting Diodes), which are used for lighting, emit light when electric current flows when an electric field is applied to the PN junction of the diode, which is a kind of electric luminescence in which solids emit light by electric fields. Features include fast turn on / off speed, low power consumption, long life, light emission of various colors, and low glare compared to other light sources for lighting.

 Therefore, in recent years, the use of flat panel lighting devices for offices and homes using LEDs is gradually increasing.

Specifically, the light steel structure extending from the ceiling is formed spaced apart at a predetermined interval, the structure of the light steel end may be formed in two forms, M-bar and T-bar, such as M-bar and T The size of the flat lighting device is different depending on the shape of the bar.

Therefore, according to the structure of the end of the light steel frame, two types of flat lighting devices having different sizes of flat lighting devices must be manufactured. In this case, manufacturing costs increase because each type of flat lighting devices must be manufactured separately, and M If the flat panel lighting device that can be installed in only one type of -bar and T-bar is sold biased, there is a problem of inventory, the manufacturing cost increases.

The present invention is applied between the back cover and the front cover and the diffusion plate and the front cover when applying the back cover and the diffuser plate of the flat lighting device applied to the structure of the light steel frame of the T-bar to the structure of the light steel frame of the M-bar It is to provide a flat panel lighting device that can solve the problems caused by the spacing occurs.

In addition, in FIG. 2B, the supporting member 140 is described as being disposed at all four corners of the front cover 120 including four corners. However, according to the shape of the supporting member 140, that is, FIG. In the case of using the supporting member 140 as shown in (b) of 4, the same effect can be obtained even if only the two corners of the four corners face each other.

The support member 140 may be formed to be detachable from the front cover 120, and may be integrally formed with the front cover 120 to be fixed to the front cover 120.

The reason for using the support member 140 is to make the use of the back cover 100 and the diffusion plate 130 more diverse.

Specifically, it will be described with reference to FIG. 3.

Figure 3 (a) is an example in which a flat lighting device is installed in the structure of a light steel frame 10 of the T-bar (11 ') form extending from the ceiling (1), Figure 3 (b) is M-bar (11) ) Is an example in which a flat lighting device is installed in the light steel frame 10 structure.

Basically, the spacing between the steel structures of the T-bar (11 ') form of the light steel frame 10 structure and the M-bar (11) form of the light steel frame 10 structure is the same. However, when the structure of the light steel frame 10 as shown in FIG. It is required that 130 is larger than the case where the lightweight steel frame 10 structure is a T-bar 11 'form as shown in FIG.

More specifically, in the lightweight steel frame 10 structure having the T-bar 11 'shape as shown in 3 (a), a part of the front cover 120' is disposed inside the T-bar 11 'and is T supported by -bar (11 '). The size of the front cover 120 'is inevitably smaller than the size of the front cover 120 used in the light steel frame 10 structure of the M-bar (11).

By filling a predetermined gap formed between the second edge portion 120b of the 120 and the diffusion plate 130 to hold the flow of the diffusion plate 130, the position of the diffusion plate 130 is fixed.

Therefore, when the support member 140 is used in this way, the H1 screw hole formed in the first edge portion 100b shown in FIG. 2B and the mounting portion 120a of the front cover 120 when the flat lighting device is installed. It is possible to easily match the H1 screw holes, there is an effect that can improve the work efficiency when installing the flat lighting device.

In addition, the back cover 100 and the diffusion plate 130 used in the structure of the light steel frame 10 of the T-bar (11 ') form according to the use of such a support member 140 more easily M-bar (11) By being able to be used in the structure of the lightweight steel frame 10), the usability of the back cover 100 and the diffusion plate 130 can be expanded to separate the back cover 100 and the diffusion plate 130 according to each type There is no need to make a separate), so the production cost can be reduced, and even if the market demand is concentrated on either the T-bar (11 ') or the M-bar (11), there is an effect that can solve the burden of inventory. .

The shape of such a support member 140 will be described in more detail with reference to the following FIG. 4.

As shown in FIG. 4, the support member according to the present invention may have various forms. In addition, the support members 140 and 140 'according to the present invention basically include the first support parts 140a and 140'a and the second support parts 140b and 140'b, and the first support parts 140a and 140'. a) and the second support portions 140b and 140'b may be integrally formed or may be formed to be separated from each other by contrast.

More specifically, as shown in (a) of FIG. 4, the shape of the first support part 140a may be formed as a surface to diagonally contact the edge of the first edge part 100b and the second support part 140b. ) May be formed to "a" to engage the edge of the diffusion plate 130. The support member 140 illustrated in FIG. 4A is the same as the support member 140 used in FIGS. 1 and 2B.

Alternatively, as illustrated in FIG. 4B, the shape of the first support part 140 ′ a is formed to be “a” so that the shape of the first support part 140 ′ a meshes with the edge of the first edge part 100 b, and the second support part ( The shape of 140'b) may be formed to “a” to be engaged with the edge of the diffusion plate 130. The support member 140 'as shown in FIG. 4 (b) can achieve the same effect even if only the two corners facing each other among the four corners have the same effect, thereby further reducing the manufacturing cost.
