Described outer tube adopts T5, T8 or T10 specification.

Described CCFL is U type or straight pipe type.

The diameter of described CCFL is 2.4mm-8.0mm.

Described inverter control circuit adopts intelligent IC half-bridge driven chip.

The connected mode of described inverter and CCFL is a both-end anti-phase high drive.

The used fluorescent material of described CCFL is the fluorescent material amalgam that special red, blue phosphor allotment forms, and the rouge and powder wavelength is 600nm～700nm, and the blue powder wavelength is 440nm～460nm.

The cold cloudy plant growth lamp of the utility model, beneficial effect is following:

1, owing to adopt cathode fluorescent tube as light source, the life-span can reach more than 50,000 hours, was 15～20 times of conventional fluorescent lamps pipe, was 5～8 times of Metal halogen lamp; Color rendering is good, and color rendering index reaches as high as 95Ra; The glass of fluorescent tube adopts unleaded anti-UV glass, has the ultraviolet function of interception, is applicable to long-time illumination, and mercury content can accurately be controlled in the fluorescent tube, is no more than 3.0mg/ and props up, and meets international standard, has protected environment.

2, fluorescent tube drives the high-frequency drive mode that adopts 50KHz above, under this high frequency, has the advantage of no stroboscopic, flicker free, can prevent visual fatigue; And light source can be because of frequent switch damage, and the switch number of times is more than 5,000 ten thousand times, long service life; And light decay is little, and long-time use does not influence its illumination.

3, the used CCFL of cold cathode plant growth lamp adopts special red, blue light powder allotment to form; The rouge and powder wavelength is 600nm～700nm; The blue powder wavelength is 440nm～460nm; Very, when not having sunlight, replace sunlight to provide one with the very close light environment of sunlight to growth and development of plants near sunlight wavelength.

4, a kind of cold cathode plant growth lamp of providing of the utility model, compact conformation all concentrates on CCFL, inverter and reflecting piece in the outer tube, and whole device inserts civil power and gets final product work, can make full use of the connection of existing T5/T8 specification lamp socket.

5, have the cold-starting function, in the time of 0 ℃ brightness unaffected ,-30 ℃ can normally start.
