The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

as Figure 1-3, a kind of LED injection moulding module that provides for the utility model embodiment, comprise the aluminium base 1 that is provided with electronic circuit, be located at the electronic devices and components on aluminium base 1, be electrically connected at the wire 4 on aluminium base 1 and cover shell 3 on aluminium base 1, wherein include LED lamp 2 in electronic devices and components, this LED injection moulding module also comprises the optical lens group 5 that is covered on each LED lamp 2, optical lens group 5 is a plurality of optical lens 51 integrated injection moldings and fits tightly on aluminium base 1, each optical lens 51 is corresponding one by one with each LED lamp 2 respectively, connection matrix 52 by strip between each optical lens 51 interconnects, the zone line that encloses after each optical lens 51 combinations is hollow structure.in the present embodiment, aluminium base 1 not only can play good thermolysis, and also plays the effect of conduction transmission in circuit layout, shell 3 employing HIPS(impact resistant polystyrenes) material is made, use the machine once injection moulding, has good water proofing property, impact resistance and wearability, optical lens adopts the PC material to make, the lighting angle that can make LED light source is the scope of 120 °～160 °, enlarged the lighting angle of LED light source, increased the irradiated area of injection moulding module, thereby can reduce the quantity of the module of arranging in unit space, make the user reduce cost, further, optical lens is when covering the LED lamp, can avoid it directly to contact with mould, thereby reduced the probability of dead lamp, simultaneously, optical lens also can make the luminous more even of LED lamp, thereby when having avoided LED lamp direct irradiation to the stimulation of eyes, light sensation is more comfortable, each optical lens is conjoined structure, also make production efficiency higher.

In the present embodiment, each independent optical lens 51 orthographic projection on aluminium base 1 is circular.

The zone line that each optical lens 51 encloses on LED injection moulding module is provided with the installing hole 6 of using for mounting fastener, and securing member can be screw or rivet etc.
