Whether you are planting dates in the Dubai desert or growing lettuce in the Nordic polar regions, the ZW series plant growth lights redefine the light energy boundaries of global agriculture with **2.9μmol/J light efficiency** and **-30℃ extreme cold start** technology.
Why choose ZW series
❶ Aerospace-grade heat dissipation, light decay reduced by 70%
▸ Adopt **aerospace aluminum + nano-coating heat dissipation system**, continuous working for 60,000 hours at 50℃ high temperature environment, light efficiency stability rate exceeds 95%
▸ Compared with traditional lamps, energy consumption is saved by 40% (with third-party test report)

LED brightness unit

Posted on by queendomlamp

LED brightness unit Luminous intensity: The measurement units of luminous intensity include illuminance unit (lux), luminous flux unit (lumen Lumen), luminous intensity unit (candle power). 1CD (candle power) refers to a completely radiated object;
Luminous intensity per sixtieth square centimeter area at the freezing point of platinum. (It used to refer to a whale oil candle with a diameter of 2.2 cm and a mass of 75.5 grams, burning 7.78 grams per hour, a flame height of 4.5 cm, and the luminous intensity along the horizontal direction) 1L (lumen) refers to 1 CD candlelight irradiated at a distance of 1 cm , the luminous flux on a plane with an area of 1 cm2.

LED light emitting diode chip material

Posted on by queendomlamp

LED light emitting diode chip material:Gallium, arsenic, and phosphorus are used in the manufacture of LED light-emitting diode chip materials, so these LEDs are commonly known as three-element light-emitting tubes.GaN (gallium nitride) blue LEDs, GaP green LEDs and GaAs infrared LED, known as a two-element luminescent tube. At present, the latest technology is a four-element LED made of AlGaInN four-element material mixed with four elements of aluminum (Al), calcium (Ca), indium (In) and nitrogen (N), which can cover all visible light and some ultraviolet light. The spectral range of light.

LED light emitting diode material and application

Posted on by queendomlamp

LED Light-emitting diodes (LEDs) are optoelectronic components made of III-V compound semiconductors, and their core is a PN junction. Under the forward voltage, electrons are injected into the P region from the N region, holes are injected into the N region from the P region, and part of the minority carriers entering the opposite region recombine with the majority carriers to emit light. The material properties (band gap width) forming the PN junction determine the wavelength of the emitted light, and for visible light, it determines the color of the light.
