Detailed description of the invention

Below by way of specific embodiment, the utility model is elaborated:

Fig. 1 is the exploded view of this utility model LED down first embodiment, this LED down, including LED light source module 10 and reflector 20, this reflector 20 is provided with the horn-like shell structure of light-emitting window 21 for top, arrange in this LED light source module 10 is arranged at this reflector 20 and near the bottom of this reflector 20, the medial wall of this reflector 20 is reflecting surface 22, this reflecting surface 22 is for reflecting light towards this light-emitting window 21, certainly, according to required light distribution, this reflector 20 can also be other structures.

Refer to Fig. 1 to Fig. 3, the interior bottom without leave of this reflector 20 is gradually increased to top, this LED light source module 10 includes pedestal 11 and is arranged at the LED light source 12 on this pedestal 11 sidewall, this pedestal 11 is arranged on the bottom of this reflector 20, the sidewall of this pedestal 11 is arranged relative to the medial wall of this reflector 20 so that the light major part that LED light source 12 thereon sends is emitted directly toward the medial wall of this reflector 20.The bottom of this reflector 20 is provided with base plate 23, and this pedestal 11 is arranged on the middle part of this base plate 23, and the sidewall of this pedestal 11 tilts relative to this base plate 23 or is vertically arranged.This pedestal 11 is boss structure, and the side wall ring of this pedestal 11 is arranged around the axis of this pedestal 11, and the sidewall of this pedestal 11 is interval with plurality of LEDs light source 12.This reflector 20 is made from a material that be thermally conductive, and the bottom of this reflector 20 has been wholely set base plate 23, and this pedestal 11 is made from a material that be thermally conductive, and this pedestal 11 and this base plate 23 thermally coupled are to be delivered to the heat that these LED light sources 12 produce on this reflector 20.This LED down is designed by modularity, can quickly be combined assembling, reduce production cost.

Wherein, also include reflector 30, within this reflector 30 is arranged on this reflector 20 and be positioned at the top of this LED light source module 10, the interval, medial wall of this reflector 30 and this reflector 20 is arranged, this reflector 30 reflects towards the medial wall of this reflector 20 for the light that this LED light source module 10 sent so that most of light that this LED light source module 10 sends penetrates towards this light-emitting window 21 after the reflection of this reflector 20 medial wall.This reflector 30 is arranged on the surface of this LED light source module 10, and the external diameter of this reflector 30 is more than the external diameter of this pedestal 11 so that more the light that these LED light sources 12 send is reflected in the medial wall towards this reflector 20.This reflector 30 and this pedestal 11 interval form gap, the size of size and this gap by arranging this reflector 30, make light full illumination that these LED light sources 12 directly send to this reflector 30 or this reflector 20.

In addition, also including diffuser 40, this diffuser 40 is the shell structure of both ends open, and one end of this diffuser 40 is fixed on the bottom of this reflector 20, this reflector 30 is fixed on the other end of this diffuser 40, the light that this diffuser 40 sends for these LED light sources 12 of transmission.

In sum, this LED down is provided with reflector 30 and the light that this LED light source module 10 sends reflexes to the medial wall of this reflector 20, penetrate after the medial wall of this reflector 20 is reflected, so, the light that this LED light source module 10 sends will not directly outgoing and direct projection to human eye so that this LED down has the advantage preventing dazzle.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, should be included within the scope of this utility model protection.
