[0028] The lamp glass 1 is made of highly transparent and light-resistant material, so that the surface of the lamp glass 1 has good light transmission performance, ensuring the brightness requirement of lighting, and the good light resistance ensures that the lamp glass is not easy to oxidize and discolor under ultraviolet rays and natural light for a long time.

[0029] The lamp housing 2 is injection molded of PC+ABS material. The PC+ABS material has good processing performance and mechanical properties, as well as good appearance quality. The excellent mechanical properties can ensure that the lamp housing performs well when subjected to impact and load, and the good appearance quality can ensure a good visual appearance on the secondary surface of the lamp. The lamp housing 2 is provided with a lamp holder hole for the lamp mounting holder 7 to extend into.

[0030] The lamp housing 2 and the lamp glass 1 together form a cavity 8. Preferably, the edge of the lamp glass 1 and the edge of the lamp housing 6 are welded together by vibration friction welding.
