The difference between plant fill light and ordinary light.
What is the difference between LED plant growth lights and ordinary lights? What is the difference between LED plant growth lights and ordinary LED lights? Today we come to popularize it for everyone. There are several types of lamps: incandescent lamps, halogen lamps, fluorescent lamps, etc., let's first look at the following types of lamps. Incandescent lamps are one of the most common lamps in life. The most commonly used lighting principle of incandescent lamps is based on the phenomenon of thermal radiation caused by filaments in vacuum or neutral gas heated to incandescent state by electric current. The advantages are simple structure, low cost, convenient use and good brightness. The disadvantages are large, the luminous efficiency is low, and the service life is short.
The halogen tungsten lamp is filled with inert gas containing halogen elements (iodide) in the incandescent lamp body, and uses the principle of tungsten halogen cycle to improve the luminous intensity and service life. Disadvantages are poor shock resistance.
Fluorescent lamps use mercury vapor to generate discharge under the action of an applied voltage, which emits a little visible light and a large amount of ultraviolet rays. The ultraviolet rays stimulate the phosphor coated on the inner wall of the tube to make it emit bright light. The service life and brightness are better than incandescent lamps. Disadvantages Long start-up time, stroboscopic flicker will occur, affecting the service life.
LED grow light LED is light-emitting diode. LED lights use solid semiconductor chips to produce luminescent materials. When a forward voltage is applied to both ends, the carrier fluid in the semiconductor recombines, releasing excess energy and causing photons to emit visible light. Advantages: high efficiency, pure light color, low energy consumption; durable and long life; safe and environmentally friendly, instant start-up; anti-vibration, cold light source, long-term lamp body surface heat is low, and good heat dissipation. Get close to the object without making it anxious. Based on this feature, the LED can be placed horizontally or vertically above the plant. Disadvantages: weak brightness and high cost.
