Description

Fresnel Lenses LED plant growth lamp

Technical field

The utility model relates to a kind of light fixture, is applicable to LED plant growth lamp & lantern lighting.

Background technology

Fresnel Lenses (Fresnel lens) is by French physicist's Augustine. and Fresnel (Augustin.Fresnel) invention, he is initial in 1822 uses this Lens Design to be used for setting up a glass Fresnel Lenses system---lightose lens.Fresnel Lenses is a kind of optical element of fine structure, sees that it resembles a boomerang plate, is made up of the concentric circles of ring by ring from front.Fresnel Lenses, have another name called Fresnel lens, mostly be to press by polyolefine material note the thin slice forming, also there is glass to make, lens surface one side is light face, another side imprinting ascending concentric circles, its texture is according to interference of light and disturb and penetrate and relative sensitivity and receiving angle require to design.The requirement of lens is very high.The lens of a slice high-quality must any surface finish, clean mark, and its thickness becomes with purposes, and how in 1mm left and right, characteristic is that area is large, thin thickness and detecting distance.Fresnel Lenses is many times being equivalent to the convex lens of infrared ray and visible ray, and effect is better, but cost is more much lower than common convex lens.

In plant production, the light source of traditional plant illumination is generally fluorescent lamp, metal halide lamp, high-pressure mercury lamp and incandescent lamp.The outstanding shortcoming of these light sources is that energy consumption is large, operating cost is high, and energy consumption cost accounts for 50%～60% of whole operating costs.In recent years, along with the development of photoelectric technology, drive the birth of high brightness ruddiness, Blue and Far-red lights light emitting diode (1ight-emitting diode, LED), made low energy consumption artificial light source become possibility in the application of agriculture field.LED has high-photoelectric transformation efficiency, uses direct current, volume is little, the life-span is long, it is low to consume energy, wavelength is fixing and the advantage such as low heating, compare with fluorescent lamp with the high-pressure mercury lamp generally using at present, not only light quantity, light quality are (red, blue light ratio or red/far-red light ratio etc.) adjustable, but also be the cold light source of lower calorific value, can irradiation at short distance, thus the cultivation of plants number of plies and space availability ratio are improved greatly.Therefore, LED is considered to 21 century agricultural and the most promising artificial light source of biological field, has good development prospect.

The light efficiency of conventional light source is not high, can not well mate with the required light source of plant well, heating is higher in addition, affects other envirment factors of plant growth, LED light source will be the principal light source of plant illumination, but also exists and much limit it by the problem of wide popularization and application.(1) high cost.Cost is the key factor that can a product obtain market competition, is even tens times more than of the several times of other light sources with the cost of the LED of power, has seriously limited its popularization on market.(2) technology maturity needs to improve, and due to the deficiency of fund input, has seriously restricted the technology content of plant illumination technology and equipment.(3) industrialization and standardization level are still very low.The LED light source that plant illumination uses is at present still in the experimental study stage, also do not form perfect standardized technique system, the exploitation of light source and use only only limit to scientific research institutions, the professional manufacturing enterprise that shortage can transform achievement in research, and also failing to form to have industry cluster mutually.(4) heat radiation of LED light source and light decay also do not solve completely, also make LED on plant illumination, have restriction.

Summary of the invention

The utility model is to solve the defect that above-mentioned LED exists, and provides a kind of stable performance, the Fresnel Lenses LED plant growth lamp of cost is low, lightweight, volume is little, perfect heat-dissipating, software Based Intelligent Control have constant voltage concurrently and constant current combines driving power.

Described heat-dissipating aluminium plate 9 adopts special aluminium fin, and cost is low, perfect heat-dissipating.

Described lamp socket 1 has striated and cellular heat radiation aperture around.

Described intelligent controller 11, after operating personnel's input parameter arranges, is sent to and on intelligent controller 11, is stored control and regulation LED illuminator 8 and carry out work according to parameter by data-interface, network interface or wireless remote control.

The power supply that described independent current source 5 can provide constant voltage and constant current to combine.

Compared with the existing technology, the utlity model has following advantage:

1, this Fresnel Lenses LED plant growth lamp, compact conformation, its uniformity of light and uniformity are fine, are suitable as light-operated to plant of macrophyte garden.

2, the fan of LED light fixture and LED chip share 1 power supply electric energy are provided, and have reduced unnecessary element, have saved the installing space of whole lamp, make the element of light fixture control more rationally, and workman assembles assembly still less.

3, good heat dissipation effect, particularly adopts special aluminium fin, the parallel installation of lamp socket, aluminium base and heat-dissipating aluminium plate; Radiator fan evenly blows to wind in shell, and lamp socket, aluminium base and heat-dissipating aluminium plate are dispelled the heat simultaneously; The surrounding of lamp bracket has striated and cellular heat radiation aperture, the service life of having improved LED chip.

4, the lampshade of this Fresnel Lenses LED plant growth lamp adopts Fresnel Lenses, makes simple and easyly, and volume is little, lightweight, has greatly saved the consumption of material, has reduced Costco Wholesale.

5, independent current source can provide the power supply that constant voltage and constant current combine, and constant pressure source power supply can be how and many strings, failure rate is low like this, and constant voltage source cost is lower, and that constant-current source can be accomplished is farthest energy-conservation, and contribute to extend the life-span of lamp.
