Description

LED Stereo Supplement Lighting Device for Greenhouse Plants

technical field

The utility model belongs to the technical field of supplementary light for greenhouse plants and is used for realizing inter-row three-dimensional supplementary light for plants, in particular to an LED three-dimensional supplementary light device for greenhouse plants.

Background technique

The growth of plants is inseparable from light. The intensity, quality and cycle of light are all issues that must be considered in the process of plant growth. In recent years, with the rise of greenhouse agriculture and ornamental agriculture, especially the huge impact of haze weather on greenhouse plants, more and more attention has been paid to the supplementary light of greenhouse plants. Due to the special growth environment of greenhouse plants, they cannot receive sufficient light, which affects the yield and quality of crops.

Existing supplementary light devices for greenhouse plants mainly include high-pressure sodium lamps, fluorescent lamps and LED lamps, among which high-pressure sodium lamps and fluorescent lamps have the problems of heat generation, large power consumption and not being environmentally friendly. Due to the high efficiency of LED lights and the optional luminous wavelength band, they have become a new choice for plant supplementary lighting. There are LED plant supplement light lamps produced by Philips abroad, and there are manufacturers such as Shenzhen Federation Heavy Industry and Shenzhen Hongyida Optoelectronics in China. "(patent number: CN201690847U), "LED semiconductor plant fill light" (patent number: CN20128867Y) and so on. The above-mentioned LED lamps mainly consider the following aspects: the ratio of different red and blue band lights is required for different growth periods of plants; the adjustable spectrum fill light designed for the spectrum matching required by different plants; the adjustment of fill light time, etc. , but the supplementary light device is almost always installed on the top of the greenhouse, and the downward light is used to supplement the light on the plants, without considering the problem of insufficient light in the middle and lower leaves of taller plants, such as corn and tomatoes.

The effect of LED light supplement for greenhouse plants is related to the distance from the lamp to the plant leaf surface. The farther the distance is, the weaker the light received by the plant is; for taller plants, the top leaves receive stronger light, and the light received by the middle and below Light attenuation is large, which is not conducive to plant growth. For traditional LED supplementary lighting devices, to obtain a better supplementary lighting effect for plants, the only way is to increase the number of lamps or increase the power of a single lamp. .

Utility model content

The purpose of the utility model is to provide an LED three-dimensional supplementary light device for greenhouse plants, which solves the problem in the prior art that LED lamps are insufficient for supplementary light for plants with taller plants.

The technical solution adopted by the utility model is that a LED three-dimensional supplementary light device for greenhouse plants includes a bracket with a double-rod structure with adjustable height and angle. The brackets are arranged in parallel along the rows of plants. There are multiple groups of motors, and the rotating shafts of each pair of motors are connected downwards with the locks at both ends of the LED lamps through steel ropes.

The LED three-dimensional supplementary light device for greenhouse plants of the utility model is also characterized in that:

LED lamps use red and blue LEDs in a ratio of 5:1-10:1.

The beneficial effect of the utility model is that, for plants with taller vertical growth such as tomatoes and corns, it is installed between the rows of plant growth to provide a three-dimensional supplementary light effect, and light-emitting diodes (LEDs) are used as supplementary The light source, the device can move with the growth of the plant, adjust the height and angle, fit the plant better, shorten the distance between the light and the leaf surface of the plant, make the leaves of the plant receive light evenly, provide three-dimensional fill light, and maximize the Make full use of light energy to promote plant growth.

Compared with the existing planar plant lighting device, the three-dimensional plant lighting method of this device, the entire lighting device is installed between the rows of plants, which can be closer to the plants and reduce the distance between the light source and the leaves of the plants , Maximize the use of light, reduce the use of lamps and save electricity.

In the figure, 1. Bracket, 2. Motor, 3. LED lamp, 4. Steel rope, 5. Lock.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

With reference to Fig. 1, the structure of the device of the present invention is, comprises the support 1 of the adjustable double-bar structure of height and angle, and support 1 is arranged in parallel along the plant row, and each support 1 is provided with corresponding multiple groups of motors 2 in pairs, The rotating shafts of each pair of motors 2 are downwardly connected with lock catches 5 at both ends of the LED lamp 3 through steel ropes 4 .

The bracket 1 can be a rectangular frame structure or a parallel double-bar structure.

All motors 2 can select miniature motors for use.

LED lamp 3 uses red and blue LEDs in a ratio of 5:1-10:1 (according to different plants or different periods of plant growth, the required lighting ratio is different, choose a suitable lighting combination), and the two ends of the LED lamp 3 are respectively passed through the lock. Buckle 5 is connected with one group of steel ropes 4, and the length of every group of steel ropes 4 is adjusted and controlled by a motor 2 on the corresponding top, and support 1 is fixed on the top of the greenhouse or at an appropriate height.

The motor 2 arranged on the rod above the support 1 is referred to as the motor M1, and the motor 2 arranged on the rod below the support 1 is referred to as the motor M2. When only the motor M1 shrinks the steel rope, the LED lamp 3 is lifted at the end close to the plant to increase the inclination angle of the LED supplementary light; when only the M2 shrinks the steel rope, the LED lamp 3 is lifted at the other end away from the plant to reduce the inclination angle of the LED lamp , the motors M1 and M2 shrink the steel rope at the same time to raise the height of the LED lamp 3 . When inter-row work is required, the motors M1 and M2 can simultaneously shrink the steel rope to raise the height of the LED lamp 3 without affecting the inter-row work. When the personnel leave, the motors M1 and M2 can release the steel rope at the same time, reducing the The height of the LED lamps is used to achieve the effect of three-dimensional fill light between rows.

The working principle of the utility model device is:

The whole set of supplementary light device is installed between the growth rows of plants, as an auxiliary supplementary light source, it can provide supplementary lighting for plants between rows. As the plant grows and the height of the plant increases, the height of the fill light and the angle of inclination can be adjusted according to the growth, so that the distance from the light to the leaf surface of each layer of the plant is reduced, so that the light is closer to the surface of the plant leaf, so that the plants can Part of the leaves receive sufficient light, which better fits the growth of the plant, achieves a three-dimensional fill light effect, maximizes the use of light energy, and promotes plant growth.
