Abstract

See full text

A light bar fixing device comprises a light bar defining a through-hole and a heat dissipation mechanism defining a threaded hole corresponding to the through-hole. The light bar fixing device further comprises a helical spring having a pitch identical to that of the threaded hole. A columnar body of the helical spring is adapted to be threaded into the threaded hole, and an outer diameter of a stop end of the helical spring is greater than that of the columnar body. By threading the helical spring into the threaded hole, the light bar can be securely connected to the heat dissipation mechanism with a clearance therebetween being reduced. Also, the light bar can dissipate heat evenly via the heat dissipation mechanism to allow a uniform temperature distribution in the light bar, thus resulting in a desirable light emitting effect and a prolonged service life of the light bar.
