Energy-saving light for plant growth

Abstract

The invention discloses an energy-saving light for plant growth. The energy-saving light comprises a diffusion cover disc, an LED light source component, a radiator, a power driving component and a light shell, wherein the light shell comprises a hollow cavity, as well as a top opening and a bottom opening which are correspondingly formed in two ends of the hollow cavity; the radiator is a metal cover body; the power driving component is arranged in the hollow cavity above the metal cover body; and the LED light source component is fixed on the bottom end surface of the metal cover body in a fitting manner and comprises a light source substrate plate on which at least one white-light LED lamp bead, a circle of blue-light LED lamp beads and at least nine circles of red-light LED lamp beads are arranged. The energy-saving light is simple in structural design, low in manufacturing cost and good in working heat dissipation effect, can effectively prevent dust, prevents dust from covering the inner side end surface of the diffusion cover disc and thus reducing the light brightness, and can meet the spectrum requirements of different or the same plants in different stages.

Description

technical field [0001] The invention relates to the technical field of plant lamps, in particular to an energy-saving lighting lamp for plant growth. Background technique [0002] Plant lights, as the name suggests, are lamps for plants. The plant lamp simulates the principle that plants need sunlight for photosynthesis, supplementing light for plants or completely replacing sunlight. However, the existing plant lights use high-pressure sodium lamps to irradiate plants to promote plant growth, but the light irradiated by high-pressure sodium lamps is a linear spectrum, but plant photosynthesis is within the range of 380-760nm of the visible light spectrum, and absorbs red light with a wavelength of 640-660nm And 430-450nm blue light mainly, therefore, the high-pressure sodium lamp that emits a linear spectrum causes a waste of light source; in addition, the high-pressure sodium lamp takes a long time to start, and the power of the high-pressure sodium lamp is high, which wa...

However, the existing plant lights use high-pressure sodium lamps to irradiate plants to promote plant growth, but the light irradiated by high-pressure sodium lamps is a linear spectrum, but plant photosynthesis is within the range of 380-760nm of the visible light spectrum, and absorbs red light with a wavelength of 640-660nm And 430-450nm blue light mainly, therefore, the high-pressure sodium lamp that emits a linear spectrum causes a waste of light source; in addition, the high-pressure sodium lamp takes a long time to start, and the power of the high-pressure sodium lamp is high, which wastes power; the surface temperature reaches 300 degrees Celsius, which is not suitable for the seedling stage. At the same time, high temperature also leads to short service life of high-pressure sodium lamps, etc.
