As further specifying of such scheme, the axis of described led light source and reflector at angle; Two led light sources and two heat-conducting plates are set in the described reflector, and the top of led light source is provided with metal cap across two heat-conducting plates, leaves the gap between two heat-conducting plates.
Described heat-conducting plate comprises transverse plate that contacts with spreader surface and the installing plate that is used to be provided with led light source, and installing plate and transverse plate have angle, and angular range is 90 ~ 135 °.
The transverse plate of described heat-conducting plate is fixed on the radiator by securing member, and this securing member adopts screw, bolt or pin.
The installing plate middle part of described heat-conducting plate is provided with caulking groove, and led light source is embedded in this caulking groove.
Described heat-conducting plate cross section is the L type, and L type heat-conducting plate is provided with back-to-back, and led light source is pasted on the sidewall of L type heat-conducting plate.
Described reflector bottom is provided with the arcwall face of pin, and an end of radiator is socketed on the arcwall face of reflector, and the other end is provided with counterbore, is provided with jack in the counterbore and patches with described pin and cooperate.
Described reflector middle part is provided with and holds the slotted eye that heat-conducting plate passes.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopts a led light source to join the package assembly of a heat-conducting plate, the heat-conducting plate that is provided with in two spaces of symmetrical distribution, reflector middle part, heat-conducting plate is fixed on the radiator by securing member, the heat that each led light source is produced all can distribute rapidly through associated heat-conducting plate, radiator, compared with prior art, thermal conductivity, thermal diffusivity and optically focused can be significantly improved.
2, heat-conducting plate of the present utility model and radiator adopt the connected mode that combination is installed, and heat-conducting plate can prepare separately, install, and can select more excellent material of heat conductivility as required for use, and adaptability is good.
3, two heat-conducting plates of the present utility model are symmetrically distributed, and it is little to take up room, and effectively solves the shadow problem that causes across reflector because of the monolithic heat-conducting plate in the prior art, and layout is more reasonable.
