Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 A COB LED lamp for plant lighting is shown, its structure includes an aluminum substrate, and a blue LED chip, a red LED chip, a white LED chip, a red LED chip, a blue LED chip and a white LED chip are packaged through COB. The quantity ratio is 10:1:1, and the red LED chip surrounds the blue LED chip and the white LED chip. The red LED chips are divided into four groups and controlled separately, and the number of red LED chips in each group is 1, 2, 3, 4 respectively. The blue LED chip and the white LED chip are a group. The blue LED chip and the white LED chip are cont...

Abstract

The invention discloses a COB LED lamp for plant illumination. The structure of the LED lamp comprises an aluminum substrate, wherein a blue LED chip, red LED chips and a white LED chip are packaged by COB. The LED lamp is characterized in that the quantity ratio of the red LED chips, the blue LED chip and the white LED chip is 10: 1: 1, and the red LED chips encircle the blue LED chip and the white LED chip. The COB LED lamp for plant illumination disclosed by the invention is small in area, high in heat dissipating efficiency, small in driving current and long in service life, and the proportion of red lights and blue lights can be randomly changed according to the demand.

Description

technical field [0001] The invention relates to the technical field of plant lighting lamps, in particular to a COB LED lamp for plant lighting. Background technique [0002] Illumination is one of the important environmental factors for plant growth. It is the energy source of plant photosynthesis and directly affects the growth and metabolism of plants. Illumination is also a signal that regulates important plant life activities such as photomorphogenesis, photoperiod response, and internal circadian clock rhythm. Restricted by geographic location, season, and meteorological conditions, natural light sources cannot be effectively used by plants, restrict crop cultivation, and their light intensity, photon flux, light quality, and photoperiod cannot be precisely controlled. Therefore, they are not the best light source for plant growth. However, these traditional artificial light sources generally have disadvantages such as high power, low luminous efficiency, large heat g...
