Description

A kind of LED module and plastic cement face shield thereof

Technical field

The utility model relates to the LED technical field, is specifically related to a kind of LED module, relates in particular to a kind of plastic cement face shield of LED module.

Background technology

The keep to the side part at place of present LED module, its front is generally as shown in Figure 1, extends uniformly-spaced some and parallel shading eaves 11 at the outer surface of plastic cement face shield 1, and the four side edge of plastic cement face shield 1 has housing 12.Combine Fig. 2 visible by Fig. 1, lamp plate 2 is gone into battle and is shown some LED lamps 21, and corresponding LED lamp 21 is provided with some silica gel face shields unit 31 on the silica gel face shield 3, on the plastic cement face shield 1 between per two shading eaves 11 then correspondence be provided with plurality of windows.After the assembling, LED lamp 21 and the corresponding silica gel face shield unit 31 that covers on the LED lamp 21 promptly are arranged in said window.Because silica gel face shield 3 adopts the silica gel of transparent (perhaps translucent) to process usually, so the light that LED lamp 21 sends can appear plastic cement face shield 1.

Silica gel face shield 3 is used to prevent that water droplet, dust etc. from falling lamp plate 2 or LED lamp 21, thus be applied on the outdoor LED module essential.And shading eaves 11 not only is used to keep the sun off and protect the LED lamp 21 on the lamp plate 2, can also play the effect at adjustment visual angle.

As shown in Figure 2, the luminous axis of LED lamp 21 and its centre of luminescence promptly are respectively the upward angle of visibility C and the downwards angle of visibility B of LED module to the minimum angles of upper and lower shading eaves.In general, the height H that reduces shading eaves 11 can increase upward angle of visibility C and downwards angle of visibility B simultaneously.But if the height of reduction shading eaves 11 as shown in Figure 3, then 21 the protective effect meetings that can play of 11 pairs of LED lamps of shading eaves reduce, even lose protective effect.Especially for the outdoor LED module, for avoiding sunlight direct projection LED lamp 21, the height of shading eaves 11 can't reduce.With the outdoor LED module, generally requiring downwards angle of visibility B is 60 degree, and the Perspective Analysis of present LED module is following: guarantee that one, downwards angle of visibility B is 60 degree.Like Fig. 2, then upward angle of visibility C is 52 degree, and the height H of shading eaves 11 is reduced to 2.0mm, and this protective effect to LED lamp 21 reduces greatly, and irradiation of sunlight is all damaged LED lamp 21 easily in production, carrying or the hoisting process.Two, sacrifice some downwards angle of visibility B.Increase shading eaves 11 and protect LED lamp 21.Like Fig. 3, downwards angle of visibility B is reduced to 54 degree, and upward angle of visibility C is 46 degree, and the height H of shading eaves 11 can be increased to 2.5mm.

In sum, increase the miopragia that downwards angle of visibility B can cause shading eaves 11, therefore can not meet the demands fully, need try every possible means to improve the structure of LED module from other aspect through the height that reduces shading eaves 11.

The utility model content

One of the utility model technical problem to be solved provides a kind of plastic cement face shield of LED module, under the prerequisite that does not reduce shading eaves height degree, increases the downwards angle of visibility of LED module.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of plastic cement face shield of LED module, its outer surface extend some shading eaves, have plurality of windows between every adjacent two shading eaves; The local location of the corresponding said window of said shading eaves downside root has some breach of dodging.

Two of the utility model technical problem to be solved provides a kind of LED module, under the prerequisite that does not reduce shading eaves height degree, increases the downwards angle of visibility of LED module.

A kind of LED module comprises plastic cement face shield and lamp plate, and said lamp plate is gone into battle and shown some LED lamps, and said plastic rubber surface cover outer surface extends some shading eaves, has plurality of windows between every adjacent two shading eaves, and said LED lamp correspondence is arranged in said window; The local location of the corresponding said window of said shading eaves downside root has some breach of dodging.

In the optimized technical scheme, said LED module also comprises the silica gel face shield, has the corresponding silica gel face shield unit of some and said LED lamp on the said silica gel face shield; Said silica gel face shield unit correspondence covers on the LED lamp and is arranged in said window, and the part of said silica gel face shield unit upside is positioned at the said breach of dodging.

The beneficial effect of the utility model is:

Because corresponding setting of the root of shading eaves downside dodged breach above window; Make that the LED lamp can be as far as possible near the shading eaves root of putting on it; Thereby under the prerequisite that does not reduce shading eaves height degree, can increase the downwards angle of visibility of LED module, thereby obtain better protection effect and display effect.

Below in conjunction with accompanying drawing the utility model is done further to describe in detail.

Description of drawings

Fig. 2 be among Fig. 1 the A-A section dissect structural representation;

Fig. 3 is that another of A-A section dissects structural representation among Fig. 1;

Fig. 4 is the positive local structural representation of the utility model specific embodiment LED module;

Fig. 5 be among Fig. 4 the D-D section dissect structural representation;

Fig. 6 is the local partial enlarged drawing of E among Fig. 5.

The specific embodiment

The LED module of this specific embodiment; Its front edge place local as shown in Figure 4; Be with the difference of existing LED module; Light cup 211 1 lateral edges of LED lamp 21 are very near the root of its top shading eaves 11 downsides, and are as shown in Figure 5 and shown in Figure 6, cause the part of silica gel face shield unit 31 upsides to stretch to its top shading eaves 11 inside.

As shown in Figure 6, the local location of the corresponding said window of shading eaves 11 downside roots has some breach 13 of dodging.This is dodged breach 13 and is communicated with said window, thereby also can be regarded as the part of window.Therefore 13 tops are covered by shading eaves 11 but this dodges breach, regard that independently to dodge breach 13 better with window as.This is dodged breach 13 and makes the part of silica gel face shield unit 31 upsides can enter into this to dodge breach 13, thus make LED lamp 21 can be more near the root of the shading eaves 11 of its top.

This kind mode need not reduce the height of shading eaves 11 when increasing LED module downwards angle of visibility B, therefore can not influence the protection effect of shading eaves 11.Though this kind mode can cause upward angle of visibility C to reduce; But when using because of the LED module; The screen body center of the LED that constituted screen generally all is higher than people's eyes, so the adverse effect that upward angle of visibility C reduces to bring is less or do not have, and downwards angle of visibility B increase can bring better display effect.

Need to prove; Some LED module for indoor application; It might not have silica gel face shield 3; Dodge breach 13 this moment and can make the root of the as close as possible shading eaves 11 of top edge of LED lamp 21, even can the upper edge of LED lamp 21 partly be stretched into and dodge in the breach 13 (but be advisable with the root that the upper edge of the light cup 211 of LED lamp 21 is no more than shading eaves 11, otherwise can influence display effect on the contrary); Also can under the prerequisite that does not reduce shading eaves 11 height, increase the downwards angle of visibility B of LED module.

Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
