Abstract

The invention discloses a lighting device. The lighting device comprises a base, fixing blocks, shiners and a reflex housing covering the base. The base is a rotary symmetric body. The base comprises an annular side face surrounding a self-rotation symmetric axis. The shiners are fixed on the annular side face through the fixing blocks. The fixing blocks are arranged close to the top of the base. The shiners are arranged close to the bottom of the base opposite to the fixing blocks. The reflex housing comprises a top cover, a reflex base and connecting strips extending to the reflex base in a radial direction from the top cover corresponding to each fixing block. The top cover covers on the top of the base. The reflex base encircles the bottom of the base. The connecting strips first extend outwards from the periphery of the top cover, bypass the fixing blocks, and bend inwards to be close to the base, therefore, the reflex base is close to the shiners on the base as far as possible, and most of the light emitting from the shiners can be distributed through reflection of the reflex base.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device using a reflector for light distribution. Background technique [0002] Most of the illuminants of existing lighting devices are welded on the aluminum substrate, and the aluminum substrate is locked on the base through a fixing block. However, many lighting devices also need to realize light distribution through the refraction of a reflective mirror covered on the base. However, due to the fixed block between the reflective mirror and the aluminum substrate, there is a large gap between the two, so that many light beams emitted by the luminous body are too far away and dissipate before reaching the reflective mirror. The efficiency of using light energy. [0003] Therefore, how to improve the use efficiency of light energy of the lighting device has become an urgent problem to be solved. Contents of the invention [0004] The technical problem to be solved by...
