The main heat dissipation methods for LED street lights are: natural convection cooling, forced cooling with fans, heat pipe cooling, and loop heat pipe cooling. The forced cooling method with fans has a complex system and low reliability, while heat pipe and loop heat pipe cooling methods are costly. However, street lights have advantages that facilitate natural convection cooling, such as being used outdoors at night, having the heat dissipation surface located on the upper side, and having relatively small size restrictions. Therefore, it is recommended to choose natural convection cooling for LED street lights whenever possible.

Product Description
The heat dissipation methods for LED street lights mainly include: natural convection heat dissipation, forced heat dissipation with fans, heat pipes, and loop heat pipe dissipation. The forced heat dissipation method with fans has a complex system and low reliability, while the heat pipe and loop heat pipe dissipation methods have high costs. However, street lights have advantages that facilitate natural convection heat dissipation, such as outdoor nighttime use, the heat dissipation surface being located on the side and top, and a relatively small size restriction. Therefore, it is recommended to choose natural convection heat dissipation for LED street lights whenever possible.
The problems in the heat dissipation design of LED street lights include: arbitrary setting of the heat sink area, unreasonable arrangement of the heat sinks, failure to consider the usage method of the fixtures in the arrangement of the heat sinks, which affects the effectiveness of the fins, emphasizing thermal conduction while neglecting convective heat dissipation. Although many manufacturers have considered various measures such as heat pipes, loop heat pipes, and thermal conductive silicone grease, they have not realized that the heat must ultimately be dissipated through the surface area of the fixture. They overlook the balance of heat transfer; if the temperature distribution of the fins is severely uneven, some fins may not function or have very limited effectiveness.
Heat-dissipating high-power LED street light fixtures. The purpose is to solve the heat dissipation problem of high-power LED fixtures by proposing an air convection cooling type high-power LED street light fixture. It includes a lamp head assembly, a lamp body heat dissipation assembly, and a lamp tail assembly. The lamp body heat dissipation assembly is an arc cylindrical shell with openings at both ends. The two sides of the arc cylindrical surface are vertical surfaces with an array of through holes. Inside the arc cylindrical shell cavity, there are 4 to 10 axially arranged thermal conductive plates fixedly connected to both the arc surface and cylindrical surface. The vertical thermal conductive plates and both sides of the arc cylindrical shell also have an array of through holes, forming 5 to 11 thermal air flow channels for heat dissipation within the lamp body heat dissipation assembly. The advantage of this utility model is that there are multiple thermal air flow channels in the cavity of the heat sink, and the vertical thermal conductive plates also serve as cooling surfaces, increasing the area for thermal exchange and improving thermal discharge efficiency.

PRODUCT DESCRIPTION
LED street lights refer to street lights made with LED light sources. They have unique advantages such as being environmentally friendly, long lifespan, fast response speed, and high color rendering index, which are very significant for energy saving in urban lighting.
Road lighting is an important component of urban lighting. Traditional street lights often use high-pressure sodium lamps that emit light in a 360-degree manner but suffer from significant light loss leading to huge energy waste. Currently, global environmental conditions are deteriorating day by day, and countries are developing clean energy. With rapid economic growth in our country, energy supply and demand contradictions are becoming increasingly prominent; there is a serious shortage in electricity supply which makes energy saving an urgent issue to address.
Therefore, developing new types of energy-saving LED street lights with long lifespans and high color rendering indices is very important for energy saving in urban lighting. Road lighting is closely related to people's production and life; as urbanization accelerates in our country, LED street lights with advantages such as directional lighting, low power consumption, good driving characteristics, fast response speed, high seismic resistance capability, long lifespan, and being environmentally friendly are gradually coming into people's view and becoming a new generation of energy-saving light sources that can replace traditional light sources worldwide. Thus, LED street lights will become a choice for energy-saving renovation in road lighting.
