Description

LED plant light supplement lamp system capable of automatically adjusting light quality ratio

Technical Field

The utility model relates to a plant light filling lamp especially relates to a but LED plant light filling lamp system of automatically regulated light quality ratio.

Background

Sunlight is a key factor for the survival of plants, and the plants need to utilize the energy of the sunlight for photosynthesis to obtain nutrients necessary for growth and development. However, in many occasions (such as plastic greenhouses, sunlight greenhouses, quick-freezing greenhouses and plant factories), because facility buildings shield sunlight to a certain extent, indoor light is insufficient, and plant yield reduction and quality reduction are caused. In order to supplement light to plants as much as possible under the condition of insufficient light, the plant lighting environment is one of important physical environmental factors indispensable to the growth and development of the plants. Most plant lamps adopt traditional fluorescent lamp, high pressure sodium lamp, metal halide lamp isotructure, and traditional plant lamp has solved the plant and has supplemented irradiant problem to a certain extent, but different plants and the required red blue light ratio of different growth stages are different, and traditional plant lamp does not have the intellectuality, can't adjust the ratio of red blue light according to specific plant and its growth state to regulating effect to vegetation is not good, and is not the best light source that supplements of plant.

In order to solve the above problems, LED plant lamps have come to be produced. The LED plant lamp can adjust the light-quality ratio according to different plant varieties, supplement light in a targeted manner, promote plant growth, shorten the time for plants to bloom and bear fruits and improve production. At present, a plurality of schemes for adjusting the light quality proportion of the LED plant lamp are provided, and the following schemes are summarized: 1. the irradiation angle of the red light is unchanged, and the irradiation angle of the blue light is changed, so that the luminous flux of the blue light irradiated on the plant is changed, and the change of the luminous flux ratio of the red light to the blue light is achieved; 2. the light-tight plate is used for shielding the number of the blue light LEDs, and the aim of adjusting the proportion of the red light and the blue light can be achieved; 3. the switch is used for switching the number of electrified blue LEDs, and the luminous flux of the red LEDs is unchanged, while the number of luminous blue LEDs is changed, so that the aim of adjusting the proportion of red light and blue light is fulfilled; 4. and (4) blending the red light and the blue light in a centralized manner. Schemes 1 and 2 need manual adjustment, cannot accurately adjust the proportion of red light and blue light, wastes electric energy, and wastes a large part of blue light luminous flux; in the scheme 3, each LED plant lamp needs to be taken down from a high place, and then hung after a switch is turned on, in addition, different light proportions are needed for the plants in different growth periods, and if a large number of plant lamps are arranged, the operation is very troublesome; in addition, the control circuit is also complex; in the scheme 4, a plurality of control wires are required to be used for each plant light, and the installation and the maintenance are very troublesome.
