The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
See also Fig. 1 and Fig. 2, the LED light-guide device 100 that the embodiment of the present invention provides comprises hollow resettlement section 20 and a plurality of pillar 30 that a roof 10, is connected with this roof 10.
This resettlement section 20 has sidewall around, and this resettlement section 20 is for accommodating a LED.In the present embodiment, this roof 10 is circular, and this resettlement section 20 is annular.In other embodiments, this roof 10 and this resettlement section 20 can be other shape, for example, all can, for square, only need these resettlement section 20 profiles corresponding with these roof 10 profiles.
The plurality of pillar 30 is formed at this resettlement section 20 away from the end of one end of this roof 10.The plurality of pillar 30 is for inserting LED circuit plate, to fix this light-guide device 100 in this LED top.In the present embodiment, the quantity of the plurality of pillar 30 is three.
This roof 10 comprises the exiting surface 14 that an incidence surface 12 and near this resettlement section 20 deviates from this resettlement section 20.This incidence surface 12 has an indent lens face 121 in the face of LED, and this exiting surface 14 has an outer convex lens 141.This indent lens face 121 aligns with this outer convex lens 141, and lays respectively at this incidence surface 12 center and this exiting surface 14 center.This indent lens face 121 can be sphere or aspherical shape with this outer convex lens 141.
This light-guide device 100 structure that is formed in one.These light-guide device 100 integral body can be made by a kind of light transmissive material.
This indent lens face 121 first spreads LED light, thereby the heat that makes LED light can concentrations, can alleviate or eliminate hot spot phenomenon, and this outer convex lens 141 further makes the diffusion of LED light as site, promotes the effect of short distance scatter.
Refer to Fig. 3, the LED light source module 200 that the embodiment of the present invention provides comprises a LED module 210 and a plurality of light-guide device 100.This LED module 210 comprises a circuit board 240, and a plurality of LED230 with array arrangement in this circuit board 240.Each this LED230 is housed in this resettlement section 20.The pillar 30 of this light-guide device 100 inserts in the locating hole 241 of this circuit board 240, to fix this light-guide device 100 in this LED230 top.
Due to caving inward and diffusion to light of indent lens face 121, the distance between LED230 and this light-guide device 100 can be dwindled, and can alleviate or eliminate hot spot phenomenon simultaneously.Owing to having the further diffusion of outer convex lens 141, this LED light source module 200 can be without other diffuser plate.
