Description

The LED illumination box

Technical field

The present invention relates to a kind of incubator, be specifically related to a kind of LED illumination box that is applied to agri-scientific research.

Background technology

In recent years,, driven the birth of (light-emitting diode is called for short LED) of high brightness ruddiness, blue light and far-red light light emitting diode, made the low energy consumption artificial light source become possibility in the application of agriculture field along with the development of photoelectric technology.LED has high-photoelectric transformation efficiency, uses direct current, volume is little, the life-span is long, power consumption is low, wavelength fixing and hang down advantage such as heating; Compare with fluorescent lamp with the high-pressure mercury lamp that generally uses at present; Not only light quantity, light quality (red/blue light ratio or red/far-red light ratio etc.) is adjustable; But also be the cold light source of lower calorific value, but irradiation at short distance, thus the cultivation of plants number of plies and space availability ratio are improved greatly.The survey article of Chinese scholar Cao Yang is pointed out; Different light medium mainly is through influencing the phytochrome (350～800 nm) in the plant corpus to the influence of fruit vegetables crop growth; Thereby the morphogenesis of controlling plant and metabolism, thereby the carbon that influences in culm length, blade shape and thickness and each organ of plant distributes.

Light quality is to the special effects of vegetable growth, but since colored fluorescent lamp, light filter or colored pvc film can't be quantitatively accurate modulated spectrum Energy distribution, regulate and control photoenvironment.Therefore, adopt new type light source that it is goed deep into systematic research and will help further to improve growth and development of plant, obtain higher output and better product quality.

In recent years; LED successfully has been used for fields such as artificial light filling, plant tissue culture, genetic breeding, plant factor and astroponics; Decline gradually and all kinds of specific wavelength Products Development along with the improving constantly of LED performance, price; LED will be more wide in the agricultural and the range of application of biological field, also causes the upsurge to LED research therefrom.Therefore, LED is considered to the agriculture and the most promising artificial light source of biological field of 21 century, has bright development prospect.

LED is applied in biology, agricultural etc. produces scientific research field; Be focus in recent years,, satisfy the indoor observation needs of biological growth and development for guaranteeing biological necessary living condition; Must there be a kind of equipment to come the simple analog microclimate environment, guarantees necessary environmental temperature and humidity.At present, led light source is applied in the agri-scientific research, the main problem that exists is difficulty because the PN junction of LED self dispels the heat, and a large amount of heat radiations of the light source that causes cause that the local temperature rising is too fast, and the local humidity that causes is therefrom crossed minor issue.

The said temperature controller can also select to open Electric Machine Control activity shelf vertical lift after reading temp probe monitor value and setting value comparison.

Setting value is set according to different biological specimens, that is to say, setting value is to adjust according to the needs of biological growth, and setting value is a scope.Led light source is opened the back in equipment energising and just can be used, and heat, cooling, humidification, dehumidification equipment need can start in setting value.As: temperature range is set in 22-26 ℃, and then temperature is lower than 22 ℃, and warming-up device starts, and temperature is higher than 26 ℃, and cooling system starts; Humidity range is set in 70%-90%, and then humidity is lower than 70%, and humidification apparatus starts, and humidity is higher than 90%, and dehumidification equipment starts, and detection realizes through temperature, moisture probe.

Said temperature controller and humidity controller are simultaneously or work independently.

The said temperature controller is the W502P temperature controller; Said humidity controller is the S522 humidity controller.Precision with better control temperature, humidity.

Above-mentioned warming-up device is meant automatic constant-temperature aluminium shell type ptc heater.

Above-mentioned cooling system is meant cooling fan or compression mechanism cool equipment.Volume hour, cooling system only refers to cooling fan, if strengthen the volume of incubator, can consider to lower the temperature with the compression mechanism cool equipment.

Above-mentioned humidification apparatus is meant single shower nozzle atomizing humidifier or many shower nozzles atomizing humidifier.Volume hour, humidification apparatus only refers to single shower nozzle atomizing humidifier, if strengthen the volume of incubator, can consider with many shower nozzles atomizing humidifier.
