LED Grow Light Benefits for Indoor Plants.

If you can see the sunshine in the plant factory? If you can, where does "sunlight" come from? If you are an indoor plant grower you definitely know the "sunlight' comes to a machine called Led Grow Light.

At first, the plant lamps used in plant factories include incandescent lamps, high-pressure sodium lamps, metal halide lamps, fluorescent lamps, and other traditional lamps, and the most popular plant lamp light source is the led light source. Since the birth of the LED light source, because of its obvious inherent advantages, it has been favored by scientific researchers and has become an efficient production tool. There are essential differences between LED light sources and traditional lamps in the luminous principle.

Incandescent lamp through the filament heating, when the filament temperature reaches a certain degree, like a hot iron to emit light, so the incandescent lamp will convert most of the electric energy into heat energy, only a small amount of electric energy into light energy. High-pressure sodium lamps, metal halide lamps, and fluorescent lamps are all gas discharge lamps. The electrons in the discharge tube are accelerated by the external electric field, which excites the gas (including some gaseous metals) to discharge and leads to atomic luminescence. The spectral characteristics are mainly determined by the characteristics of the gas components themselves. LED is a solid-state light source, and its core is the PN junction made of semiconductors. P-type semiconductors (containing higher concentrations of holes) and n-type semiconductors (containing higher concentrations of free electrons) are usually made of different semiconductor compounds. The space charge region formed at their junction is called the PN junction. Through the migration and recombination of electrons and holes in the PN junction, it emits light. Different PN junction compounds have different luminescence properties.

What kind of advantages does led grow light have compare to Others?

First of all, Led Grow Light is efficient and energy-saving. After the Led Grow Light are used in agriculture, the use density of lamps is very high compared with general lighting, especially for plants with high light demand, and the power consumption per square meter of the planting area is as high as 500-1000W. This puts forward strict requirements for the electro-optic conversion efficiency of the light. At present, the electro-optic conversion efficiency of Led Grow Light is more than 20 times of incandescent lamp, 3 times of fluorescent lamp, nearly 2 times of high-pressure sodium lamp and metal halide lamp. Therefore, the application of Led Grow Light can greatly reduce power consumption, to achieve energy saving.

Secondly, the led spectrum has a wide range of coverage, so it is easy to obtain monochromatic light and all-optical spectrum. At present, LED can cover the wavelength range of 200-950 nm, and there are dozens of monochromatic LEDs. The fluorescence powder can be excited to widen the half-wave width of monochromatic light, or the composite spectrum of monochromatic light, or to obtain the white light of the whole spectrum. This provides a very favorable experimental condition for the study of light absorption of different plants, and realizes the spectral customization of different plants, and provides the best light formula for plants.

Third, the spectrum of Led Grow Light can be adjusted. LED is a current-driven light source, and its brightness increases with the increase of current. Therefore, adjust the power output current of the driving led to getting the corresponding brightness. The spectrum can be adjusted by controlling the current of LED with different light colors. At present, the adjustable spectrum grow lights on the market are mainly used for scientific research, and the adjustable light intensity plant lamps have been widely used in production.

Fourth, LED Grow Light has less heat and can contact plants in close range without causing problems such as plant leaves and operator burning. The rapid development of indoor multi-layer planting technology is mainly due to the characteristics of Led Grow Lights.

Fifthly, Led Grow Light has longer life, low light attenuation, and high reliability. The theoretical life of LED is more than 100000 hours. If the design of the Led Grow Light can control the working temperature of LED under the appropriate temperature, the life of the Led Grow Light can exceed 50000 hours. At present, the warranty period of high-end LED Grow Lights is 5 years, and the light attenuation is still less than 10% after 36000 hours of operation. When the fluorescent lamp works for 10000 to 15000 hours, the light attenuation is usually as high as 30%.

Sixth, Led Grow Light has strong controllability and great potential for intelligent control. Traditional lamps, such as high-pressure sodium lamps, need more than 5 minutes from power on to stable working state and need cooling for about 10 minutes after power off to start again. The response speed of Led Grow Light is very high, and it can work normally under the condition of 30000 times of fast switching per second.

Seventh, high safety in use and high reliability in transportation. Traditional lights are mostly made of glass shells, which will inevitably be damaged due to broken glass during transportation and use. Led Grow Light is a solid light source, which has a high tolerance to vibration, drop and impact, and is safe and reliable.

Eighth, the form of lamps and lanterns is diversified. The traditional light source is generally bulb type. When it is made into a plant lamp, a reflector is often added to make its light shine down on the target plant. The Led Grow Light can not only be made into the top light with downward light but also can be made into the complementary light between plants with 360 degrees light. Unlike the 360 degrees light of traditional light source bulbs, the LED package is generally 180 degree single-sided light, which makes it easier to obtain small-angle light. It can be used as a projector to focus light on plants, and can also be made into a panel type plant lamp with uniform light in close range.

Because of its advantages side, the application of LED plant lamps in agriculture has developed rapidly in recent years. Nowadays, compared with traditional lamps, the cost of LED Grow Light is still high, but with the progress of science and technology, the cost of the Led Grow Light will be cheaper and cheaper. In the short future, Led Grow Light will make the plant grow easier.
