What are related to the lifespan of LED sports stadium light

 

For the LED sports lighting system, the heat dissipation problem is as important as the optical problem. The heat dissipation performance directly affects the luminous stability and service life of the LED sports lighting.

 

Therefore, in the case of the same power, the length of service life of the LED stadium luminaire depends mainly on the performance of the heat-dissipating material used in the luminaire and the structural design of the luminaire.

 

In the era of vicious competition of brands, there must be breakthroughs in LED heat dissipation. The most direct way to improve the luminous stability and service life of LED stadium lights is to have a very strong heat dissipation technology.

Poor heat dissipation directly leads to reduced service life of LED lamps

 

Since LED lamps convert electrical energy into visible light, there is a problem of conversion rate, which cannot convert 100% of electric energy into light energy. According to the law of conservation of energy, excess electric energy is converted into heat energy. If the design of the heat dissipation structure of the LED lamp is unreasonable, this part of the heat energy cannot be quickly eliminated. Therefore, since the LED package is relatively small in volume, a large amount of heat energy will be accumulated in the LED lamp, resulting in a decrease in life.

 

The lighting system solution - using aluminum, and unique thermal design, combined with good thermal and insulating properties, can extend the life of LED stadium lights and improve the actual luminous flux, compared with other LED lamps,  the working state of the LED sports lighting system ensures a lifetime of 100,000 hours.

 

The quality of the material is degraded and the light decay problem occurs.

 

Usually, the stadium lamps are used for a long time, and some materials are easily oxidized. As the temperature of the LED lamps rises, these materials are repeatedly oxidized at a high temperature, the quality is lowered, and the life is shortened. At the same time, due to the switch, the luminaire causes multiple thermal expansion and contraction, which causes the strength of the material to be destroyed, which easily leads to the problem of light decay.

 

The heat dissipating material used is uniformly dispersed. The structure is compact.The material is light and waterproof. The surface is not easy to rust. The material has low thermal resistance. The heat conduction is fast, and the durability is durable. Thereby solving the problem that the general LED stadium lamp is prone to aging and light decay.

 

Long-time overheating may cause inconsistencies in light color

This is a common problem of LED lamps. When the temperature of LED stadium lamps rises, the impedance of electricity increases, resulting in an increase in current. The increase in current causes heat to rise. This reciprocating cycle, more and more heat, eventually causes color discoloration, resulting in light. Poor stability.

 

Reduce the temperature rise, and have better ventilation holes in the structure design of the luminaire

 

According to the principle of air circulation, when there is a temperature difference between the two areas, the OAK LED heat dissipation system will exchange hot and cold air through the ventilation channel, so that the air structure flows by its own structural design, so that the heat dissipation effect of the lamp is greatly improved. In addition to the heat-dissipating materials, the structure design of the luminaire also plays a very important role in the heat-dissipation technology!

LED cooling technology is an important technical problem in the LED industry!
