Laser light installed inside cavity of bulb lamp and method of assembling laser light inside cavity of bulb lamp

A method of assembling a laser light inside a cavity of a bulb lamp, comprising steps of:

• (1) inserting a transparent piece, a grating piece, a lens base, a lens, a lens fixing base in sequence into a focus base, and meanwhile, assembling the focus base, the transparent piece, the grating piece, the lens base, the lens, and the lens fixing base in an integrated manner into a lens module by means of a fastener of the lens fixing base;
• (2) inserting a laser head into a laser head base, connecting the laser head with the lens module in a threaded connection manner by engaging male threads of the focus base with female threads of the laser head base, and then engaging a heat dissipating tube with a bottom of the laser head base, whereby a laser module is assembled;
• (3) inserting the assembled laser module into a fixing support, connecting the laser module with a PCB board by a wire, mounting the fixing support at an opening of an LED light board, and guiding screws through screw holes of ear shaped parts of the fixing support and screw holes of the LED light board to fixedly connect the fixing support with the LED light board;
• (4) ultrasonic fixing a transparent cap with a lamp cover, and finally fastening the lamp cover to a lamp holder to complete the installation.
