Introduction to the characteristics of full-spectrum growth lamps
LED is an abbreviation for LED. The difference between LED and HID is that LED emits light by semiconductor, while HID emits light by glowing, luminescent plasma gas. When current is passed through the LED, light is emitted in the center of the bead as a different color of the crystal as a function of the different materials used. The crystal is surrounded by a reflector, which is an epoxy lens, which is sealed by an epoxy envelope.
The full-spectrum growth lamp consists of an LED lamp bead, a heat sink, a fan, a power supply, and a housing. A single lamp bead is in contact with the heat sink, and the heat sink and the fan together derive the heat emitted by the LED. The LED power supply is similar to the power supply used by HID to power the LEDs. A new generation of full-spectrum growth lamps use optical lenses to achieve the effect of concentrating and enhancing the intensity of the light.
Full-spectrum growth lights have opened up a new world for indoor growers. Now we can control the wavelengths that plants are actually receiving, rather than adjusting our planting methods based on the wavelengths available on the market. We can make different plant lights according to different plants. The characteristics of the full-spectrum growth lamp, especially its low heat, paves the way for large-area planting.
Low heat is a feature that can be utilized by a full-spectrum growth lamp. As we discussed earlier, a full-spectrum growth lamp produces very little heat. Of course, heat is a more complicated topic, or it is left to those physicists. What we need to know is what happens when we turn off the lights? Light quantum no longer exists, where are they going? Physicists tell us that they disappear into the entire system, and this system refers to our entire production room. This is the law of conservation of energy that we know. Energy can be converted but will not disappear. It's hard to say when the light fades, but it turns out to be heat. Theoretically 1W is equal to 3.412 BTU of heat. This equation applies to any fixture, HID, fluorescent, LED or other lamp. How is this really the case, then why does LED produce less heat? The reason is simple. When people use LEDs, they use wattages that are 40%-50% lower than HID. A low wattage means low heat.
Note: The infrared heater works by heating the surface and then raising the ambient temperature. This is the opposite of the traditional heater, which heats the ambient temperature first and then raises the surface temperature of the object. Remember, in your garden, these so-called object surfaces refer to the torso and leaves of your plant.
Another reason for the low heat generated by LEDs is HID, which generates a lot of useless heat in the infrared. The principle that infrared can be the surface temperature of an object has been applied to everyday life for many years. For example, infrared heating is used in the bathroom, and infrared is used in the hotel to maintain the temperature of the food. Recently, infrared microwave ovens and barbecue grills have also been on the market. Infrared has no other effect than raising the temperature around your plant. If the luminaire manufacturers publish their spectral distribution maps and their spectra contain infrared, we can easily understand why their lamps are so hot. If the spectral profile can show wavelengths above 900 nm, we can compare the heat generated by the plant lights of different light sources.
