With the advent of module street lamp, the lighting industry has set off a second revolution. As a light source, module street lamp is not only energy-saving and environmentally friendly, but also has a long service life, which is in line with the environmental protection, energy-saving and low-carbon products advocated by the country. The traditional LED module street lamp design mainly focuses on the lumens of the LED, while less attention is paid to the heat dissipation of the LED lamp.

There is now a new type of modular LED module street lamp, which improves the heat dissipation effect of the LED module street lamp and prolongs its service life. The module street lamp separates the front and rear lamp housings by partitions, and is characterized in that the front lamp housing is provided with a light original plate, the light source board has a silicone grease layer, and a plurality of LED light source modules are fixed on the light source board , The front lamp housing between two adjacent LED light source modules is provided with a convection groove, the front of the plurality of LED light source modules is provided with a lamp shade, there is a trainee between the plurality of LED light source modules, and the back of each LED light source module Fin-type heat sinks are respectively provided, and fine-grained grooves are arranged on the fin-type heat sinks; a junction box and a power supply are respectively provided in the rear lamp housing.

The module street lamp is characterized in that there are wiring grooves on the inner side of the front lamp housing, the light source board is made of aluminum substrate, and the thickness is 2mm, the material of the fin-type heat sink is aluminum alloy, and the thermal conductivity is 203W/M* K. The modular LED structure is reasonable and compact, and the heat conduction effect is good. There is a convection groove in the housing and a gap between adjacent LED light source modules. The fin-type heat sink and the fine-grained groove on the The air contact area greatly improves the heat dissipation effect and prolongs the service life of the LED street lamp.

However, in the field of high-power module street lamp products, due to the different LED luminous efficiency technologies, about 15~25% of the input electric energy will be converted into light energy, and the remaining 75~85% will be converted into heat energy, so the conversion efficiency is not high. . In addition, considering the lighting needs of different environments, a good module street lamp needs to be considered in heat dissipation and optical design.
