Abstract: A light source module provided includes a heat sink, a circuit board, a lamp shade, and a fixing member. The circuit board is provided with one side tightly attached to the heat sink, and the other side is provided with a plurality of light sources. The lamp shade is provided with a plurality of optical lenses, the plurality of the optical lenses are respectively formed by a plurality of recesses forming on a front surface of the lamp shade, and a plurality of arc protrusions corresponding to the plurality of the recess forming on a back surface of the lamp shade. The fixing member is configured to fix the lamp shade on the heat sink to receive the circuit board in a space defined by the lamp shade and heat sink. Further, a lighting apparatus is also provided.

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.
