LED-COB plant growth light source

Abstract

The invention discloses an LED-COB plant growth light source. The LED-COB plant growth light source comprises a circuit board, and a plurality of light source bodies are distributed in the middle of the upper side of the circuit board, mainly comprise the red, blue and green LED chip light source bodies and are bonded to the circuit board through solid crystal base gel; the wavelengths of red light are 620-630 nm, 60-670 nm and 730-740 nm; the wavelengths of blue light are 450-460 nm and 460-470 nm. The wavelength of green light is 530-540 nm. With LEDs (light emitting diodes) as the light source bodies, the growth cycle of plants is shortened; through the design of the light source bodies and optical bands, the brightness and color development of a whole lamp are improved, meanwhile, thedifferentiation of multiple lateral branches and buds is promoted in the growth process of the plants, the growth of roots, stems and leaves is accelerated, the synthesis of carbohydrates and vitaminsin the plants is accelerated, and the growth cycle is shortened.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an LED-COB plant growth light source. Background technique [0002] Aquarium plant growth light is a kind of plant light. It uses LED (light-emitting diode) as the light source. According to the law of plant growth, sunlight must be needed. Light instead of sunlight is used to grow plants. The spectral band covered by traditional aquarium plant growth lights Incomplete, poor brightness and color rendering. Contents of the invention [0003] The purpose of this invention is to propose a LED-COB plant growth light source, which overcomes the above-mentioned deficiencies of the prior art, and uses LED (light-emitting diode) as the light source to help shorten the growth cycle of plants; At the same time, the brightness and color of the whole lamp can also promote the differentiation of multiple lateral branches and buds during the growth process of plants, accelerate...
