Preferably, being circumferentially uniformly provided with multiple glasss of valves in reflector upper end, formed lack between adjacent cup valve two-by-two
Mouthful.The purpose of notch is set, is because if having blister or lampshade outside LED lamps reflector, in some specific blisters
Or lamp
On cover, a circle dark space may be generated although there is no problem for the distribution curve flux of lamp, on blister or lampshade, notch is set,
Make the part light-transmissive of reflector external LED light source, solve issuable dark space on blister or lampshade.
Preferably, the loophole of multiple hollow outs is circumferentially provided on the wall of cup of the close upper end of reflector.Loophole is set
Purpose, be the luminous intensity distribution performance in order to advanced optimize LED, make the part light reflection of reflector external LED light source, part light
Transmission, make LED light sources all directions light intensity evenly.Also there are the blister or cover surface of the possibility setting for making outside simultaneously
The effect of brightness evenly.
Preferably, from top to bottom the reflector is made of the connection of multistage cup body, the busbar of reflector is broken line, every section
Cup body is along the circumferential direction sequentially connected by multiple curved slabs and formed again, and cross section, the longitudinal section of curved slab are arc, and every
Block curved slab be all from outside to reflector center at be bent.Such mode, the LED light sources point being suitable for outside reflector
Cloth removes the equally distributed situation on the rim of a cup circumference of reflector outer into several blocks, each LED light sources block with it is reflective
The curved slab of cup corresponds to, and can obtain in spatial distribution light distribution evenly or other light distributions.
