Company Information

Shenzhen Royalighting Co., Ltd was established in 2010, our managerment team has more than ten years of valuable experience in LED industry.  We are mainly engaged in manufacturing LED special light sources. We also accept OEM/ODM.


 1. Which kind of light have an effect on the growth of plants?

280 ~ 315 nm: minimal effects on morphological and physiological process;

315 ~ 400 nm: chlorophyll absorbs less, photoperiod effect, prevent stem elongation;

400 ~ 520 nm (blue):  chlorophyll and carotenoid absorption proportion is the largest, the biggest influence of photosynthesis;

520 ~ 610 nm: pigment absorption rate is not high;

610 ~ 720 nm (red): chlorophyll absorption rate is low, have significant effects on photosynthesis and light cycle effect;

720 ~ 1000 nm: absorption rate is low, stimulate cell elongation, flowering and seed germination;

> 1000 nm: converted into heat.


2.  the advantage of LED light source that use in plant growth light

LED is small, light, solid, long lifespan, special wavelength, low voltage, high luminous efficiency, low energy consumption, safe, reliable and durable, with larger flux. In addition, the LED light is Ⅲ, V compound light, with a narrow spectrum, spectrum and a half wide range from several nanometers to tens of nanometers, is about 20 nm +, wavelength coincide with morphogenetic spectrum of plant photosynthesis and light. Therefore the LED as plant special-purpose lighting, whether efficiency or effect will have an advantage than the traditional light, for the traditional light source is generally for the band, if with fluorescent lamp as light source, need to add a filtering to obtain the specific wavelengths of light, this will reduce the utilization ratio of light and the illuminant to be filtered is likely to be converted into the form of heat.
