Abstract: A lighting fixture includes a bracket and at least one light source module assembled on an inner side of the bracket. Each light source module includes a radiator, a circuit board, a cover plate and a fixture assembly. A plurality of light sources are arranged on one side of the circuit board, the other side of the circuit board contacts the radiator, the cover plate is provided with a plurality of optical lenses, and the fixture assembly is connected with the radiator to press the cover plate against the radiator in a manner that the cover plate is uniformly stressed on its periphery. Therefore, with no stress concentration on the cover plate, and even if the cover plate becomes brittle and prone to cracking in a salt fog or alkali fog environment for a long time, the cover plate won't really crack.

Abstract: A power chamber of a lighting fixture includes a chamber body receiving at least one power module. One of the power module and the chamber body includes a first fixing plate defining a sliding groove sunken inwards from a surface of the first fixing plate. The other one of the power module and the chamber body includes a fastener whose end is matched with the sliding groove. The power module and the chamber body are connected together through the fastener which is inserted into the sliding groove, therefore simple to assemble and disassemble. The power chamber can be a profile structure with low manufacturing costs. Power chamber cover(s) can be arranged on the side of the lighting fixture and can be integrally molded with pipes used for fixing the light source module.

Abstract: A LED street lamp comprises a connector, a power supply assembly and a light source assembly, the connector is provided with a structure of internal toothed rings, the light source assembly comprises two supporting aims and a plurality of light source modules, the assembling and disassembling of the street lamp are convenient and the maintenance cost is thereby decreased.
