Problems solved by technology

The artificial light source in the existing household plant factories mainly adopts two forms: white LED light source or red and blue LED light source. Although the latter can meet the conditions of the ratio of red and blue photons, it has the disadvantage of dazzling light.

Embodiment Construction

[0012] The design method will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] An LED lighting fixture for a family plant factory provided by the present invention includes: a lamp board, on which a first LED chip composed of a red LED chip and a blue LED chip in series is arranged on the lamp board, and a red LED chip and a blue LED chip A second LED chip composed of blue LED chips connected in parallel (the two chips have independent positive and negative pins); the first LED chip and the second LED chip are excited to produce white light acceptable to human eyes, and the generated The ratio of the number of red and blue photons is 9:1.

[0014] In a preferred embodiment of the present application, the spectral structure generated by the lamp is adjusted according to the ratio of the phosphor, so that when the red LED chip in the second LED chip passes the maximum rated current, the red The ratio of the number of ...

Abstract

The invention provides an LED lighting fixture for a home plant factory. According to the LED lighting fixture, the requirements of being conducive to human visual comfort can be met, and the spectralstructure of the light source and the number of photons can also be adjusted. Moreover, many advantageous effects not available in the prior art can be achieved by adjusting the number ratio of the red and blue photons to 9:1 which is favorable for the growth of vegetable and crop.

Description

technical field [0001] The technical field of lighting fixtures of the present invention particularly relates to an LED lighting fixture used in a family plant factory. Background technique [0002] At present, the light sources for growing vegetables in plant factories and greenhouses mainly come from artificial light sources. The light design of this light source is directly related to the quality and yield of the planted products. The difference between the number of red and blue photons in the growth light of most vegetables The ratio has certain requirements, and the ideal ratio is about 9:1. The artificial light source in the existing household plant factories mainly adopts two forms: white LED light source or red and blue LED light source. Although the latter can satisfy the condition of the ratio of red and blue photons, it has the disadvantage of glaring light. The shortcomings of these existing artificial light sources have made it difficult for home plant factor...
