Description

A kind of facility cultivation canopy horizontal bidirectional LED light compensating apparatus

Technical field

The utility model belongs to facilities horticulture plant culture artificial light source technical field, is specially a kind of facility cultivation canopy horizontal bidirectional LED light compensating apparatus.

Background technology

Facilities horticulture is the important form of modern agriculture, can carry out the intensive cultivating anti-season of vegetables, flowers, fruit tree and Chinese medicine in facility (greenhouse, plant factor, hot house etc.) inside produces, but have multiple crop index height, output height, envirment factor is an adjustable advantage such as anniversary production, be the main mode of production that satisfies gardening product demands such as urban and rural residents winter-spring season vegetables, have irreplaceable effect.China is facilities horticulture big producing country, and facilities horticulture cultivated area and output occupy first place in the world.Yet, because the planting form of China's facilities horticulture is based on heliogreenhouse and hot house, illumination in the facility has only about 70% outside the facility, under severe weather conditions such as overcast and rainy snow mist, illumination wretched insufficiency in the facility, the low light level is few according to the formation with yield and quality of growing that is seriously restricting protected crop.In China, the successive cloudy days phenomenon that bad weathers such as overcast and rainy snow mist cause happens occasionally, and the low light level is few according to often causing crop failure even total crop failure under low temperature acts on simultaneously, and economic benefit can't guarantee.Especially at the metropolis periphery, the atmospheric transparency that air pollution causes is hanged down and has also been aggravated the generation and the harm of successive cloudy days phenomenons.

Artificial light filling is to guarantee the few important technical according to facilities horticulture good quality and high output under the condition of the low light level.Yet traditional light filling lamp as high-pressure mercury lamp, exists that energy consumption height, light efficiency are low, spectrum and photosynthesis of plant demand differ defective far away, is difficult to guarantee the demand of the High-efficient Production of protected crop.LED is a kind of semi-conductor solid-state light source, have that volume is little, in light weight, energy-conserving and environment-protective, long-life, spectrum can be by advantages such as plant demand modulation, more traditional light filling light source has incomparable photoelectricity advantage, is to substitute the perfect light source that conventional light source is carried out efficient light filling.What is more important, led light source are cold light source, can press close to the plant leaf blade surface irradiation, have reduced irradiation distance, have improved biological light efficiency.

It is main that present plant culture LED artificial light source technology adopts ceiling light more.Because the problem that led light source ubiquity light is weak,, output, the quality tool of crop had a significant impact so, limited that lower leave is photosynthetic effectively to carry out to tall and big plant light filling poor effect such as tomato, cucumber.In order to address this problem, the utility model has been done further improvement to existing plant culture led light source device.

Further, the convex surface of described substrate is a curved surface, perhaps is spliced by a plurality of planes.

Further, described radiating piece is close to the inner surface of described substrate, and fill with Heat Conduction Material in the slit therebetween.

Further, the epitaxial part of described radiating piece is a zigzag.

Further, the material of described substrate is an aluminium, is aluminium base.

Further, the ruddiness of described substrate surface and blue LED lamp pearl be arranged in parallel, and many rows can be set.

Further, ruddiness and blue-ray LED optical wavelength are respectively 620～700nm and 420～500nm, and ruddiness and blue-ray LED light intensity ratio are 2～8:1.

Further, described lampshade and substrate is surperficial parallel.

Further, described lampshade edge is provided with and is beneficial to the inclination angle that enlarges the light range of exposures.

Further, described LED light compensating apparatus also comprises the power line that connects described ruddiness and blue LED lamp pearl.

Further, on lamp housing, be provided with suspension member,, be used to hang this LED light compensating apparatus such as suspension ring etc.

Facility cultivation canopy horizontal bidirectional LED light compensating apparatus of the present utility model, can be implemented in while bilateral light filling between crop row, can regulate ratio and wavelength red, the blue LED lamp pearl according to the needs of Different Crop, adopt the substrate of evagination can make light-emitting area (irradiated area) bigger, and irradiation evenly.The utility model can realize canopy in the ranks or the canopy inner near apart from light filling; also can be by a plurality of light fixture polyphones; realize the vertical large span large tracts of land of levels light filling; it is the artificial light filling technology of a practicality and high efficiency; not only reduce the light fixture usage quantity, row is done plant and can be realized abundant light filling, and be convenient to the intensive management of scale.The utility model has changed the artificial light filling of facilities horticulture plant culture, and to adopt ceiling light be main conventional art more, for the application of led light source device in the facilities horticulture light filling provides new way.
