Heat Dissipation of LED Stadium Lights

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

Therefore, in the case of the same power, the service life of the LED stadium lights mainly depends on the performance of the heat dissipation materials used by the lights and the structural design of the lights.

Poor heat dissipation directly reduces the service life of LED lights.

Since LED lights convert electric energy into visible light, there is a conversion rate problem, which cannot convert 100% of the electric energy into light energy. According to the law of conservation of energy, the excess electric energy will be converted into heat energy. If the heat dissipation structure design of LED lights is not reasonable, this part of heat energy can not be quickly eliminated, then due to the relatively small size of LED packaging, LED lights will accumulate a lot of heat energy, resulting in reduced life.

LED stadium lights system solutions – patent heat dissipation material combines the composition such as aluminum, expanded graphite, silicon powder, the advantages of good thermal conductivity and insulation performance, can prolong the service life of the LED lights and lanterns of pitch and improve the actual flux, compared with other LED lights, LED lights system working condition to ensure life over 50000 hours.

The degradation of material quality leads to the problem of light decay.

Usually, the stadium lights are used for a long time, and some materials are easy to oxidize. With the rise of the temperature of LED lights, these materials are repeatedly oxidized at high temperatures, and the quality will decline and the service life will be shortened. At the same time, because of the switch, the lights cause multiple thermal expansions and cold contractions, so that the strength of the material is destroyed, which easily leads to the problem of light decay.

In order to solve this problem, the LED stadium light system also has a unique technology, the heat dissipation materials used are evenly dispersed, compact structure, light and waterproof, the surface is not easy to rust, low thermal resistance of the material, fast heat conduction, durable, in order to solve the general LED stadium lights are easy to aging and light failure problem.

Overheat for a long time can easily cause inconsistent light color of lights.

This is a common fault of LED lights. When the temperature of LED stadium lights rises, the electrical impedance increases, leading to the increase of current, and the increase of current leads to the increase of heat. Thus, the repeated circulation leads to more and more heat, which will eventually cause discoloration of light and lead to poor stability of light.

In terms of light and color effect, the LED stadium light system has the advantages of high stability, high reliability, ultra-high thermal conductivity, etc., which can well maintain the constant illumination level and the consistency of light and color.

To reduce the temperature rise, there should be a better ventilation channel in the structure design of lights and lanterns.

According to the principle of air circulation, when there is a temperature difference between two areas, the LED stadium light system will exchange hot and cold air through the vent channel, so that the air flows up by its own structural design, so that the heat dissipation effect of the lights is greatly improved.Therefore, in addition to the use of patented cooling materials, the structural design of lights and lanterns in the heat dissipation technology also plays a very important role!

Through the innovative application of a special LED low-energy thermal resistance aluminum matrix composite heat dissipation material and product structure design, the LED sports lighting heat dissipation technology is a small step ahead of the industry, so that its products can improve the energy conversion rate of LED stadium lights, while getting rid of the trouble of LED stadium lights heat dissipation.
