Abstract

The embodiment of the utility model relates to a bottom case of an LED module, wherein the position of the bottom case, corresponding to an LED lamp, is provided with a transparent mask with ray refraction effect. The embodiment of the utility model also provides the LED module. By adopting the embodiment of the utility model, a novel LED module combination structure can be provided and comprises the transparent mask with ray refraction effect to the LED lamplight, so that the LED lamp is well protected while good color mixture effect of the LED lamplight is achieved, the use of waterproof glue of the LED module can be reduced, the production cost of the LED module can be decreased, and the weight of the LED module can be reduced.

Description

The drain pan of LED module and LED module

Technical field

The utility model relates to the LED field, relates in particular to a kind of drain pan and LED module of LED module.

Background technology

At present, the application of LED module on various demonstration message boards or display screen more and more widely, its advantage is that production technology is simple and efficient is high.As shown in Figure 1, what traditional outdoor LED module adopted is the combining structure of assemblies such as drain pan 1, cover plate 2, led circuit plate 3, led circuit plate 3 is provided with LED lamp 4, drain pan 1 is provided with the perforation of LED lamp, LED lamp 4 is exposed outside drain pan 1, LED lamp perforation side on the drain pan 1 also is provided with baffle plate 5 and plays the rainwater drainage, in order to reach good waterproof effect, needs to fill the marine glue of one deck thicker (general 5 millimeters) between led circuit plate 3 and cover plate 2.Adopt traditional outdoor LED module, can produce following technical problem: the LED module need consume a large amount of marine glues and be filled between led circuit plate 3 and the cover plate 2, has increased the production cost of LED module, and has improved the weight of LED module.

The utility model content

The utility model embodiment technical problem to be solved is; a kind of drain pan and LED module of LED module are provided; a kind of new LED module combining structure can be provided; it comprises the transparent face mask that LED light is had refraction effect; when reaching good LED light colour mixture effect, the LED lamp has been played protective effect, reduce the consumption of LED module marine glue; reduce the production cost of LED module, and reduced the weight of LED module.

For solving the problems of the technologies described above, the utility model embodiment adopts following technical scheme: a kind of drain pan of LED module, be provided with the transparent face mask with anaclasis effect with LED lamp correspondence position on the described drain pan, described drain pan and described face shield are the single injection-molded structure.

A kind of LED module, comprise drain pan, cover plate, and being arranged at led circuit plate between described drain pan and the described cover plate, described led circuit plate is provided with the LED lamp, is provided with the transparent face mask with anaclasis effect with described LED lamp correspondence position on the described drain pan.

The beneficial effect of the utility model embodiment is: by drain pan and the LED module that a kind of LED module is provided; be provided with transparent face mask with LED lamp correspondence position on the described drain pan with anaclasis effect; like this; a kind of new LED module combining structure can be provided; it comprises the transparent face mask that LED light is had refraction effect; when reaching good LED light colour mixture effect; the LED lamp has been played protective effect; reduce the consumption of LED module marine glue; reduce the production cost of LED module, and reduced the weight of LED module.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.

Description of drawings

Fig. 1 is the structural representation of the LED module of prior art; Fig. 2 is the schematic perspective view of the LED module of the utility model embodiment; Fig. 3 is the cross sectional representation of the LED module of the utility model embodiment; Fig. 4 is the longitudinal section schematic diagram of the LED module of the utility model embodiment.

The specific embodiment

The utility model embodiment provides a kind of LED module as shown in Figure 2, it mainly comprises drain pan 6, cover plate 7, and be arranged at led circuit plate 8 between drain pan 6 and the cover plate 7, led circuit plate 8 is provided with LED lamp 9, be provided with transparent face mask 10 with LED lamp 9 correspondence positions on the drain pan 6 with anaclasis effect, particularly, drain pan 6 is the single injection-molded structure with face shield 10, be that face shield 10 is integral structure with drain pan 6, except that face shield 10 was transparent, drain pan 6 was an ater, and the cross section of face shield 10 is circular, form the shape of circular protrusions in appearance, face shield 10 adopts high transparent Merlon, and (the LED module adopts the marine glue waterproof for Polycarbonate, PC) material, can fill some marine glues at seam crossing between drain pan 6 and the cover plate 7 and the position that screws particularly, in addition, on drain pan 6 edges, also be provided with and be used for the installing hole 11 that fixes with installing rack, like this, only need LED module and on-the-spot installing rack be held together and get final product with Plastic Bandage, easy for installation and rapid.

The LED light colour mixture principle of face shield 10 is, when the LED lamp 9 of various different colours is luminous in the face shield 10, each LED lamp 9 all has certain lighting angle, when not having the face shield 10 of this sealing, can not in the LED luminous point, play the colour mixture effect, but just can play the colour mixture effect after will arriving LED lamp 9 outer certain distances, after adopting the face shield 10 of sealing, LED lamp 9 is in face shield 10 when luminous, when versicolor light will see through the face shield 10 of sealing, face shield 10 can play refraction action to light, and versicolor light is mixed, make that luminous color is more even, color saturation is better.

As a kind of embodiment, face shield 10 can also adopt acrylonitrile-butadiene-phenylethylene copolymer (AcrylonitrileButadiene Styrene, ABS) other high perspex materials such as material, or high transparent glass material etc.

As a kind of embodiment, frosted finish effect can be made or letter out transparent (mirror-smooth) effect etc. in the inside/outside surface of face shield 10.

As a kind of embodiment, drain pan 6 and face shield 10 can also separate the die sinking moulding except the integral structure of making single injection-molded, when being combined into the LED module, need fill some marine glues at the seam crossing between drain pan 6 and the face shield 10.

The drain pan and the LED module of the LED module of above-mentioned the utility model embodiment are mainly used in the open air, certainly, also can be used for indoor.

The above is the specific embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
