What kind of environment is LED plant light most suitable for plant growth?

The wavelength of LED plant light is very suitable for plant growth, flowering and fruiting. Generally, indoor plants and flowers will grow worse and worse with time. The main reason is the lack of light irradiation. The LED light that is suitable for the required spectrum of plants can not only promote their growth, but also extend the flowering period and improve the flower quality.
The application of this high-efficiency light source system to agricultural production such as greenhouses, greenhouses and other facilities on the one hand can solve the shortcomings of the lack of sunlight that causes the taste of tomatoes, cucumbers and other greenhouse vegetables to decline, and on the other hand, it can also advance the winter greenhouse solanum vegetables. It will be listed around the Spring Festival to achieve the purpose of off-season cultivation.
When driving an LED plant light through a buck regulator, the LED often conducts the AC ripple current and DC current of the inductor according to the selected output filter arrangement. This will not only increase the RMS amplitude of the current in the LED, but also increase its power consumption. This can increase the junction temperature and have an important impact on the life of the LED.
When it is lower than the LED turn-on threshold (the turn-on voltage threshold of a white LED is about 3.5V), the current passing through the LED is very small. Above this threshold, the current increases exponentially in the form of a forward voltage. This allows the LED to be shaped as a voltage source with a series resistor, with a warning note: this model is only valid under a single working DC current. If the DC current in the LED changes, then the resistance of the model should also change immediately to reflect the new operating current. Under a large forward current, the power dissipation in the LED will heat the device, which will change the forward voltage drop and dynamic impedance. It is very important to fully consider the heat dissipation environment when determining the LED impedance.
Adjustable brightness requires a constant current to drive the LED plant light, and the current must be kept constant regardless of the input voltage. This is more challenging than just connecting an incandescent bulb to a battery to power it.
