technical field

The utility model relates to an LED lighting fixture, in particular to a light-emitting diode light source module with an independent heat dissipation structure.

Background technique

The use of LED lamps as lighting lamps has the advantages of low energy consumption and long service life, and thus has been widely used. At present, the traditional LED outdoor lighting is usually composed of a lamp body and a heat sink. When assembling, the LED lamp body and the heat sink are all sealed and assembled in the shell. This structure consumes more materials and is heavier. Under the premise of heat dissipation effect, usually the weight of an outdoor lighting lamp is about 10 kg, which increases the structural requirements for installation and makes the overall cost high, which is not conducive to the popularization and application of LED outdoor lighting lamps. Moreover, when a common LED outdoor lighting lamp breaks down and needs to be repaired, the entire lamp body needs to be dismantled, which also has the disadvantages of inconvenient maintenance and high maintenance cost. In addition, with the continuous development of technology, the power efficiency of LED lights is also constantly improving. When upgrading traditional LED outdoor lights, they can only be replaced as a whole, which is time-consuming and expensive.
