Polycrystal excited full-spectrum plant growth lamp

Abstract

The invention discloses a polycrystal excited full-spectrum plant growth lamp. The polycrystal excited full-spectrum plant growth lamp comprises a lamp bead and a direct-current drive power source; the lamp bead comprises a substrate support, a plurality of near ultraviolet light, purple light or blue light LED chips with different wave length peak values are packaged on the substrate support and are coated with fluorescent powder of various colors, pins of the near ultraviolet light, purple light or blue light LED chips are connected to a positive electrode and a negative electrode of the direct-current drive power source, the near ultraviolet light, purple light or blue light LED chips emit near ultraviolet light, purple light or blue light in the electrified state, the near ultraviolet light, purple light or blue light stimulates the fluorescent powder to emit corresponding light, and therefore a light source mainly comprising red and blue light wave bands can be obtained and is more suitable for plant growth. The spectrum distribution range of the light source is 350-830nm. The polycrystal excited full-spectrum plant growth lamp is suitable for simulating sunlight and providing light needed by plant growth in closed space such as underground space and indoor space, the light mainly comprises the red and blue light wave bands and meets the plant growth requirements better, and therefore plants can be promoted to fast grow, the yield of vegetables and melons in agricultural production can be increased, and the practicability is high.

Description

technical field [0001] The invention relates to a plant growth lamp, in particular to a full-spectrum plant growth lamp excited by polycrystals. Background technique [0002] Light is a necessary condition for green plants to realize photosynthesis, and light is needed in all stages of plant germination, growth, flowering, and fruit formation. Under normal circumstances, plants generally absorb energy from sunlight to achieve photosynthesis. Many types of green plants are vegetables that people eat daily. In modern agriculture, a large number of vegetables and fruits need to be planted to meet the huge demand of people. In order to avoid the impact of changes in the natural environment on plant growth, people plant vegetables and fruits in a closed environment, and provide plants with simulated sunlight through fluorescent lamps. However, the light emitted by ordinary traditional fluorescent lamps cannot fully satisfy the large The light environment required for the growth...
