Abstract

The utility model relates to a semiconductor illuminating source device for regulating plant growth, which belongs to an illuminating device. The utility model comprises a lamp shade 1, a power supply line 3, a riser joint 2, a circuit board 4, a leading leg 5, a heat distribution plate 6 and a packaging high power LED lamp 7. The utility model has long service life which can reach about 100 thousand hours and has small size and low energy consumption, and luminous efficiency is similar to fluorescent lamps and sodium lamps. The utility model also has good humidity resistance and can overcome the unsafe hidden danger in greenhouses caused by high humidity. After experimental verification, the utility model can be used for adjusting greenhouse illumination of long-day plant, short-day plant, day-neutral plant, long-short insolation plants or short-long insolation plant. The utility model is an ideal product for replacing traditional lighting luminaire in the planting greenhouses of contraseasonal vegetables and flowers.

Description

Coordinate plant growth semiconductor radiation source device

One, technical field

The utility model belongs to the what lighting device, particularly a kind of semiconductor illuminating light source device of using of coordinate plant growth.

Two, background technology

Along with the raising of people's quality of the life, the market demand of vegetables in improper season, flowers etc. is more and more vigorous.According to scholarly forecast, in 10 years futures, quite a few vegetables, flowers etc. will derive from artificial greenhouse, thereby high-efficiency agriculture greenhouse gardening and corresponding room light photograph are had higher requirement.The room light of existing greenhouse gardening shines, main employing fluorescent lamp, sodium lamp or tungsten lamp wait does the plant growing light source, problems such as these traditional radiation sources exist that energy consumption is big, life-span weak point, poor stability, light source colour are single can not satisfy the illumination of different times of plant, different vegetative stages and regulate requirement.

Three, summary of the invention

At the defective that above-mentioned prior art exists, plan high power type LED (light emitting diode, as follows.) room light that is used for greenhouse gardening shines, manufacture and design a kind of coordinate plant growth semiconductor radiation source device, so that the room light of greenhouse gardening is regulated the needs that more help plant growing according to realizing area source irradiation, the purpose that the life-span is long, energy consumption is low, light source colour is changeable and safety is good to satisfy illumination.

The technical scheme that the utility model adopted is as follows.

A kind of coordinate plant growth includes lampshade and power line with semiconductor radiation source device, it is characterized in that:

1) it also has lifter connector, circuit board, pin, heat sink and encapsulation high-capacity LED lamp;

2) the lifter connector is fixedly connected on the lampshade outer surface, and circuit board is arranged in the lampshade cavity, and heat sink is arranged on below the circuit board and with lampshade and links to each other, and the encapsulation high-capacity LED lamp is fixed on the heat sink and by pin connects with circuit board.

Said encapsulation high-capacity LED lamp is preferably alternate with purple LED lamp with red, white, Lan Se, lays at least 3 row lamp groups and is fixed on the heat sink.

The coordinate plant growth of the utility model structure semiconductor radiation source device, its basic functional principle is: by circuit board the 220V alternating current is converted to 18～24V direct current, and put on the both positive and negative polarity of LED irradiation light of series connection, merge to produce exciton after hole under electric field action on the both positive and negative polarity and electronics enter active layer, exciton gives off energy and the active layer luminescent substance is made a leapleap forward by ground state produce luminous energy to excitation state.

Radiation source device of the present utility model can be by the light wave of any one color in gauge tap selection redness, blue look, white or the purple, to realize the adjusting of various demand of plant growth; Can regulate the distance of radiation source and plant by the lifter that links to each other with connector, to satisfy the requirement of plant to Different Light intensity; Can realize the irradiation of area source by the multiple row LED lamp group that is laid in the booth, make illumination more evenly rationally plant; Its long service life can reach about 100,000 hours; Its volume is little, and it is low to consume energy, and luminous efficiency and fluorescent lamp, sodium lamp are close; And its humidity resistance is good, can overcome the hidden danger that the humidity height is brought in the booth.Experiment showed, that it can be widely used in long-day plant, short day property plant, day intermediate plant or length sunshine and shortly longly say booth room light according to plant according to regulating.In vegetables in improper season, the flower shed in future were planted, radiation source device of the present utility model was the ideal product that substitutes traditional radiation source, has the market prospects of reality and potentiality.
