LED plant lights, about 60% of the electricity can be converted into plant light PAR, the rest of the electricity is converted into heat
Let me start with the conclusion. Generally speaking, the better the heat dissipation of LED plant lights, the lower the temperature rise, the higher the luminous efficiency and the higher the reliability of the service life. However, in places where the planting environment temperature needs to be increased, a higher lamp temperature may be a good choice (in the case of not affecting the service life)
Folding & array type plant light, low temperature rise, long life and high efficiency
LED lights produce no heat radiation, In energy conversion, part of the energy is converted into light, and a large part of it is converted into heat, so the LED also generates heat.
Excessive temperature will seriously affect the luminous efficiency, life and reliability of LEDs, and heat dissipation is very important for LED light.
How to deal with the heat problem of LED plant lamps:
- Improve the energy conversion rate, that is, increase the luminous efficiency of LED lamps. High-efficiency LEDs can reduce the heat generated by LED lamp beads. There are many ways to improve the luminous efficiency of LEDs, such as directly using high-efficiency LED chips, or reducing the LED drive current, that is, derating using LEDs.
- Increase the heat dissipation area or improve the heat dissipation characteristics
- External ventilation and heat dissipation
Horticultural LED quantum board, with relatively high temperature rise, suitable for low temperature environment, need to pay attention to ventilation and heat dissipation in summer
Most of the time, we should choose LED plant lamps with lower temperature rise. The higher the reliability of the whole lamp, the longer the lifespan. The LED plant lamps with the same heat dissipation area and power have higher efficiency.
In the actual application of LED plant lights, the temperature rise of the lamp is not as low as possible. This should be considered according to the use environment and the temperature required for planting crops.
For example, in cold regions, when planting medicinal plants and tomatoes, the temperature of the planting environment needs to be increased, and the temperature rise of LED lamps can actually reduce additional temperature control costs and reduce energy waste.
According to the actual scene of the application, choosing the corresponding plant light is undoubtedly the best choice, which is also the most difficult.
