Abstract

The invention discloses a laser device plant light. The laser device plant light comprises a circuit board. A semiconductor laser device pipe core is packaged on the circuit board, and a light uniformizing piece which is matched with the circuit board in shape covers the semiconductor laser device pipe core. The semiconductor laser device pipe core is an edge emitting type laser device, and a semiconductor laser device is electrically connected with the circuit board through an L-shaped heat sink. The L-shaped heat sink comprises an L-shaped negative electrode layer, an L-shaped insulating layer and an L-shaped positive electrode layer. An L-shaped groove is formed in the inner surface of the L-shaped negative electrode layer. The L-shaped positive electrode layer is embedded into the L-shaped groove. The L-shaped insulating layer is arranged between the L-shaped negative electrode layer and the L-shaped positive electrode layer. The laser device plant light can provide light rays with the wave length required by plants, and the laser device plant light has the obvious advantages of being good in spectrum performance, high in power, short in response time, small in size, high in reliability and durability, low in cost, long in service life, environmentally friendly, capable of saving energy and the like.

Description

technical field [0001] The invention relates to a laser plant lighting lamp and a preparation method thereof, belonging to the technical field of plant lighting lamps. Background technique [0002] Light is one of the basic factors for plant growth and development. Light quality has regulatory effects on plant growth, morphogenesis, photosynthesis, material metabolism and gene expression. As the fourth-generation new lighting source, LED lighting has many important characteristics different from other electric light sources, such as energy saving and environmental protection, safety and reliability, small size, light weight, easy to disperse or combine control, etc. With the explosive growth of plant factories, the market for plant lighting will further expand, and the main reasons for the increase in the number of plant factories are as follows: 1. China's urban population has increased sharply, and the number of farmers has continued to decrease, while plant factories hav...
