Detailed description of the invention

For understanding content of the present utility model further, by reference to the accompanying drawings and embodiment the utility model is described in detail.

Embodiment 1

As shown in Figure 1, a kind of LED with high transmission rate, it comprises module lens 2, LED lamp bead 5 and transparent silica gel 6, wherein, described LED lamp bead 5 adopts the mode of paster to be arranged on module aluminium base 1, module aluminium base 1 is arranged on module group radiator 3, the top of LED lamp bead 5 is provided with transparent silica gel 6, module lens 2 covers in transparent silica gel 6, module lens 2 adopts PC lens, and PC lens production efficiency is high, and when general LED is normally run, temperature can reach 80 degree, and the temperature of PC lens is no more than 110 degree, meet the instructions for use of LED.Between LED lamp bead 5 and transparent silica gel 6, and all very close to each other between transparent silica gel 6 and module lens 2, reflect when the light preventing LED from producing is propagated in atmosphere, improve the transmissivity of light, reach 93%-95%, effectively eliminate stroboscopic; Silica gel quality is light, and volume is little, can not affect LED module load; Decrease loss, the loss that light causes at refracting process, distribute with the form of heat, heat can increase the temperature of LED lamp bead and lens, in the course of time performance and the life-span of lens and LED lamp bead be can reduce, and then performance and the life-span of whole LED module affected, after adding silica gel, there is not loss in the communication process of light, improve the service life of LED module; Although add silica gel, but there is not impact to LED lamp bead 5 performance, and can play the effect of guard lamp pearl, lamp pearl is in the past when assembling, gap is there is between lamp pearl and lens, in assembling process, collide with unavoidably, damage can be caused to the outer surface of lamp pearl, after using silica gel, pearl contacts with silica gel lamp, and silica gel is the soft surface can not damaging LED lamp bead 5, plays a protective role to lamp pearl; Transmissivity while not increasing electric energy, increases the brightness of LED after improving, and saves the energy, cost-saving.

As shown in Figure 1, the two ends of module lens 2 are connected with module group radiator 3 by rubber seal 4; Module group radiator 3 plays the effect of heat radiation, the shape of rubber seal 4 is T-shaped, comprises platform 41 and boss 42, and the two ends of module lens 2 are equipped with groove 21, groove 21 matches with boss 42, is in order to module lens 2 is connected more tight, firm with module group radiator 3 like this.

Increase one deck silica gel between LED lamp bead 5 and lens, described silica gel is transparent material, free from foreign meter, and the layer of silica gel of interpolation can also be other common colloids, can anti-aging, anti-oxidation, is soft colloid.Because silica gel is soft, lens cover is on lamp pearl, and silica gel contacts with lamp pearl, silica gel is soft, can contact, can not cause damage to lamp bead surface with LED lamp bead 100%, eliminate the space between lens and lamp pearl,, parallel across layer of silica gel, there is not refraction effect in the light that LED lamp bead sends, direct irradiation is on lens, after assembling after light scioptics, irradiate out, transmissivity reaches 93%-95%.Assembling process: be first coated with last layer silica gel in the inner side of concavees lens and module lens 2, then will scribble the lens cover of silica gel in LED lamp bead 5, simple and convenient assembly.

The light transmittance improving LED in prior art is many to be solved from material, such as change the material of lens, lampshade, although can light transmittance be improved, but the production cost of LED module can be made to improve, and silica gel relative cost in the utility model is low, and can light transmittance be improved, reduce the production cost of LED module, improve the performance of enterprises.

Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
