Abstract
The utility model discloses a spotlight with bevels arranged on the root portion of a heat conduction pillar. Light of LED light sources reversely arranged at the bottom of a cooling substrate evenly is evenly reflected out through a reflection cup, and the LED light sources arranged on the top of the heat conduction pillar can be cooled in a conduction mode through a lamp holder radiator, and can also be cooled through convection of surrounding air; due to the fact that the reflection cup is matched with the bevels on the root portion of the heat conduction pillar, light at the bottom of the reflection cup cannot directly irradiate the bottom of the heat conduction substrate, and energy loss is reduced. The spotlight with the bevels arranged on the root portion of the heat conduction pillar is simple in structure, good in cooling effect and high in luminous efficiency, and can meet the requirement of an annularly-arranged article for illumination.
