Today, we can see LED lens lights everywhere, such as the light box light source next to the subway bus station, and the signage signs in the airport that use LED light sources are all lens lights. These lens lights have one thing in common. The LED lenses are mainly made of PMMA and PC materials, and their materials have low temperature resistance, so too much heat will directly affect the use of the LED lenses. How to reduce the effect of heat on the LED lens?

Short-term use of the LED lens in an overheated environment will cause color drift and reduce light output; if it is in such an environment for a long time, the light decay will be accelerated and the lifespan will be shortened.

In order to avoid the impact of high temperature on lamps, designers usually use natural (passive) and artificial (active) cooling systems to dissipate heat. Passive cooling is a cooling system that does not contain energy-consuming electrical equipment such as heat pumps, fans or fans. The most common passive cooling device for cooling the LED lens is the heat sink. Generally, the heat sink is composed of many groups of metal fans, which can quickly conduct the heat accumulated in the LED light source and LED lens. Since the heat sink itself does not consume energy, it is the most energy-efficient heat dissipation system. However, with the continuous increase of the power of the LED light source, the heat dissipation area is required to be larger and larger, which requires the design of the heat sink with complex shape, which also takes up more space. space, but this is not conducive to the design of lamps. Designers use active cooling systems to dissipate heat from LED light sources and LED lenses. Active cooling systems use energy-consuming mechanical devices such as pumps, fans or fans in the cooling system. An active cooling system is necessary for small lamps using high-power packaged LED light sources, because it allows the lamps to be smaller in structure and size. The use of active heat dissipation is generally high-end LED lighting products.

The above are the requirements for heat dissipation of LED lenses.
