Background technique

Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. High-pressure sodium lamps emit 360 degrees of light. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in my country has become increasingly prominent, and there has been a serious shortage of power supply. Energy saving is an urgent problem to be solved at present. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great significance to energy-saving urban lighting. LED street lamps are semiconductor lighting lamps. It is a high-efficiency solid-state light source that can emit light with weak electric energy based on the semiconductor PN junction. It has the characteristics of environmental protection, pollution-free, low power consumption, high luminous efficiency, and long life. Therefore, LED street lights will become an energy-saving transformation of road lighting. best choice. the

Since the LED lamp is installed inside the closed body, a large amount of heat will be generated in the lamp body if it is turned on for a long time. If it is not discharged in time, the inside of the LED lamp will generate high temperature, which is very easy to burn out the internal components. Therefore, the LED lamp needs to be equipped with a heat sink. components to dissipate heat. The existing heat dissipation technology for LED street lamps generally adopts the method of heat conduction plate, usually using a piece of copper plate, which is actually a uniform temperature plate, and evens out the heat source; there are also heat sinks installed to dissipate heat, but the contact area between the heat sink and the air is relatively large. Small, the heat dissipation is not ideal. If the heat sink is added, although the heat dissipation effect will be improved, it will increase the weight of the street lamp, which will easily cause safety hazards to the road; in addition, there are also heat dissipation by installing a heat dissipation fan, but its structure is complex and reliable. Low reliability and high cost are not conducive to widespread adoption. the

Based on the above deficiencies, therefore, a heat dissipation assembly with simple structure and good heat dissipation effect is required. the

Detailed ways

As shown in Figures 1 and 2, it is a heat dissipation assembly 100 according to Embodiment 1 of the present utility model, including a heat dissipation plate 1, the heat dissipation plate 1 has a heat conduction surface 1a and a heat dissipation surface 1b, and the heat conduction surface 1a is equipped with an LED lamp ( Not shown in the figure), the heat dissipation surface 1b extends upwards with a number of heat dissipation columns 2, the heat dissipation columns 2 are arranged in an array, each heat dissipation column 2 is cylindrical, the heat dissipation column 2 is a hollow tubular structure and the upper end To communicate with the outside, the side wall of the cooling column 2 is provided with a number of vents 21 . the

Specifically, the air vent 21 can be a round hole, or a strip-shaped slit. The air vent 21 in this embodiment is a slit 21 opened along the length direction of the heat dissipation column 2. The slit 21 has two The roads are respectively located on two sides of the heat dissipation columns 2 opposite to each other. The gap 21 is opened from the upper end of the heat dissipation column 2 to the lower end of the heat dissipation column 2 , dividing the heat dissipation column 2 into two semicircular structures. By opening two slits 21, external cooling air can quickly flow into the heat dissipation column 2, thereby achieving rapid cooling. the
