As preferably, being provided with a through hole at the middle part of LED-baseplate, being correspondingly provided with perforate on the end face of heat radiating cup, reflection shield is communicated with the internal maintenance of heat radiating cup by through hole, perforate。
As preferably, the lower end of reflection shield is inserted in through hole。
As preferably, described reflection shield is connected by click on fashion with LED-baseplate。
As preferably, described reflection shield is cylindrical, and LED chip is distributed in the LED-baseplate outside reflection shield。
As preferably, this LED also includes lampshade, and the cervical region that described lampshade includes spherical main and the outward opening along spherical main one end extends, the total height of described lampshade and the diameter ratio of spherical main are more than 0.85。
As preferably, this LED also includes plastic shell, and heat radiating cup is coated on wherein by described plastic shell, and between the outer surface and the inwall of plastic shell of heat radiating cup, filling has the heat conduction glue for filling up gap between the two。
As preferably, described LED-baseplate is screwed on heat radiating cup。
Compared to prior art, the present invention adopts by adding a reflection shield in the middle of described LED-baseplate, light alignment surrounding is made to spread, simultaneously, reflection shield is communicated by the present invention with heat radiating cup, make use of the inner space of reflection shield, the part components and parts in power module are placed in inside reflection shield, solve and cause the little problem that cannot place of power source space because of big cell-shell。
Furthermore, the present invention adopts the lampshade of big photodiffusion material, makes light spread afterwards downwards, and the height of lampshade and diameter ratio are more than 0.85, in combination with the purpose reaching 260 degree of wide-angles。
It addition, the present invention adopts the technique of encapsulating, between the outer surface and the inwall of plastic shell of heat radiating cup, fill heat conduction glue, fill up gap between the two, reach good heat radiation purpose。
