What are the heat dissipation measures for LED street light lamp holders

Nowadays, LED street light lamp holders generally use a heat-conducting plate, using a millimeter-thick copper plate that is actually a uniform temperature plate, but its weight is generally very large because it needs a heat sink to dissipate heat. However, the weight problem is the top priority in the entire system of street lamp heads. The height of general street lamp heads will be more than meters. If it is too heavy, it will increase its risk, especially in natural problems such as earthquakes and typhoons. accident.

In fact, when it comes to the heat dissipation method of the LED street lamp cap, most of them use cooling methods such as installing a cooling fan for forced heat dissipation or natural convection heat dissipation and so on. However, cooling methods such as installing a fan are not highly reliable and the system is complicated, and some other cooling methods are costly. Products are generally used at night, which is in line with the natural convection heat dissipation method, so it is generally recommended to choose this method for heat dissipation.

The area of u200bu200bthe heat dissipation fins of the LED street light lamp holder can be set at will. However, the arrangement of the heat dissipation fins is often unreasonable. For example, sometimes the specific use of each lamp is not considered, which affects To the heat dissipation effect of the heat dissipation fins.

However, even many LED street lamp manufacturers have considered various measures, such as adding heat pipes, or adding thermally conductive silica gel, etc., but the main reason is that even if you do not know it, heat is still needed in the end. Rely on the external surface area of u200bu200bthese lamps to disperse. If the uniformity of heat transfer is ignored, some of the fins may not play their role or play a limited role.
