Description

Enhanced heat dissipation structure of street lights

technical field

The utility model relates to a lamp cap structure of a street lamp, in particular to an enhanced heat dissipation structure of the lamp cap of a street lamp using a light-emitting diode as a light source.

Background technique

The structure of the known street lamp is that the bent extension end of the upright light pole is assembled with a hollow lamp housing, and an illumination source is arranged inside the hollow lamp housing, and through the light-transmitting lampshade at the bottom of the lamp housing, nighttime illumination of the road and the surrounding environment is provided. Known street lamps require high brightness, so most of them use high-power, large-size lighting sources, such as incandescent bulbs, mercury lamps and other illuminants, but the lighting efficiency is poor, which causes serious power consumption. When this energy is increasingly scarce and precious, it is really not It is a temporary choice, and the heat generated by the high-power and large-sized lighting source is difficult to dissipate from the housing, resulting in excessive temperature of the housing or burning of the lighting source, requiring frequent maintenance and replacement, wasting manpower, material resources and time .

With the global energy-saving issues becoming more and more fermented and the governments of various countries will gradually ban incandescent bulbs in the future, light-emitting diodes (LEDs) have gradually become popular in the lighting market with their advantages of high efficiency, energy saving and adjustable optical rotation. Applications such as car lights, outdoor lighting, and situational lighting have become the focus of global attention.

Nevertheless, when using light-emitting diodes for lighting purposes at present, because street lamps require higher light illuminance, high-power light-emitting diodes are usually used as light sources, and higher currents are applied to light-emitting diodes to obtain higher Light illuminance; however, when the light brightness and illuminance increase, the heat generated by it will inevitably increase. If the heat generated is not discharged in time, it will not only easily cause heat accumulation around the LED, but also reduce the luminous efficiency, cause light decay, and even affect the life of the LED.

Furthermore, because the street lamp is installed in an open space outdoors, when the sun shines, because the inside of the lamp post is a closed space, the internal heat energy cannot be discharged and the temperature rises sharply. The life of electronic equipment is shortened, especially electronic materials such as power supplies (such as batteries, etc.), control components, etc. Whether the power supply works normally directly affects the power source of the street lamp, and whether the control components are normal is related to whether the street lamp can operate normally.
