Abstract

The invention discloses a lighting device for promoting plant growth, which comprises a bracket, a light source arranged on the bracket and used for lighting plants and a control module, wherein the control module comprises an illumination intensity sensor, a distance sensor and a microprocessor. The growth height of the plants is detected by the distance sensor, and the distance sensor detects the distance between the top ends of the plants and the distance sensor. Then, the microprocessor adjusts the distance between the light source and the ground according to the distance detected by the distance sensor, so that the distance between the light source and the top ends of the plants is kept constant; and according to the distance between the light source and the ground, an angle adjusting mechanism is controlled to adjust the inclination angle of a reflector and control the number of LED lamps emitting light in the light source, the size of the lighting field of the light source and the light emitting power of the light source are automatically changed according to the growth condition of the plant, and the light energy utilization rate in the plant growth process is effectively improved, the plants can be fully illuminated, and waste of light energy and electric energy can be reduced.

Description

technical field [0001] The invention relates to the technical field of plant lighting, in particular to a lighting device for promoting plant growth. Background technique [0002] In order to increase the yield of edible plants, LEDs (Light Emitting Diode) with specific tuned spectra are widely used in plant cultivation, enabling plants to grow for a longer period of time each day, thereby shortening the growth cycle of plants. [0003] Traditional light sources generally have a fixed light distribution angle, and the position of the light source is fixed. The illumination field of the light source is thus also fixed. However, some plants vary greatly in height during the growing season, and the difference in height may exceed one meter. Therefore, the light source needs to have a larger light distribution angle to provide a wider lighting field to ensure that when the top of the plant reaches a higher position as the plant grows, the light can be evenly distributed among ...
