Description

For example, the Chinese patent publication No. CN202040708U discloses an LED street lamp with a heat dissipation function, and the conventional device utilizes the working heat effect of an LED and a central hollow channel of a lamp post to form a chimney effect, so that gas flow is automatically generated, the heat dissipation capacity of the LED street lamp is enhanced, and the service life of the LED is ensured. However, the existing device mainly relies on the working heat effect of the LED and the chimney effect formed by the hollow channel of the lamp post to dissipate heat. However, this heat dissipation method may be limited by environmental conditions such as wind speed, air temperature, etc., resulting in unstable heat dissipation effect. Particularly in high temperature, windless or less wind speed environments, the heat dissipation effect may be greatly compromised, thereby affecting the working life of the LED. In the existing device, the assembly process of the LED street lamp is complex, and a professional is required to carry out fine operation. This not only increases the installation cost, but may also affect the installation efficiency. In addition, because the installation and adjustment of the LED street lamp in the existing device are relatively fixed, the flexibility is lacking. This may result in a street lamp that may not achieve optimal lighting or heat dissipation in certain installation scenarios.
