With the development of technology, night activities have become various, and the varieties of lamps have also begun to increase. In the case of the same power, the service life of the stadium lighting mainly depends on the performance of the heat dissipation material used in the lighting and the structural design of the lighting. The heat dissipation performance directly affects the luminous stability and service life of LED sports lighting fixtures.
1: The material quality is reduced and the light decay problem appears
Generally, some materials of stadium lamps are easily oxidized when used for a long time. As the temperature of LED lamps rises, these materials will be repeatedly oxidized at high temperature, and the quality will decrease and the life span will be shortened.
At the same time, the lamp is switched on and off, causing multiple thermal expansion and contraction, which destroys the strength of the material and easily leads to light decay.
2: Long-term overheating may cause inconsistent light color of lamps
When the temperature of the LED stadium lamp rises, the electrical impedance increases, resulting in an increase in current, and the increase in current leads to an increase in heat. In this way, the reciprocating cycle will cause more and more heat, which will cause the light color to change, resulting in poor light stability.
3: Poor heat dissipation directly leads to a reduction in the service life of LED lamps
Since LED lamps convert electrical energy into visible light, there is a conversion rate problem. Electrical energy cannot be converted into light energy. According to the law of conservation of energy, excess electrical energy is converted into heat energy.
If the design of the heat dissipation structure of the LED lamp is unreasonable and this part of the heat energy cannot be quickly removed, then due to the relatively small size of the LED package, a large amount of heat energy will accumulate in the LED lamp, which will reduce the life span.
Structural features of LED stadium lights
1. Our lamps are tailor-made according to the different characteristics of the stadium, anti-glare, high uniformity, non-dazzling, comfortable, without any light pollution;
2. The body of the 1200W flood light is made of high-quality aviation aluminum profiles, which has higher heat dissipation efficiency; and adopts phase change heat dissipation technology, and the structure adopts air convection design to ensure the heat dissipation effect;
3. The special lighting source for the gymnasium adopts imported high-quality high-power lamp beads, which has high brightness, and the light color is integrated with the stadium, and has a long life and softer light;
4. The stadium spotlight power supply adopts intelligent chip control to achieve the effect of voltage stabilization and steady flow, which ensures the long-lasting life of the lamps. It is the new first choice for environmental protection and energy saving light sources in the new era!
