Summary of the invention
Technical problem to be solved by this invention provides a kind of cold cathode floodlight, adopts cathode fluorescent tube as light source, has overcome the shortcoming of existing floodlight, and life-span length, anti-frequent switch, light decay is little, volume is little.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of cold cathode floodlight, comprise outer cover and the face shield that is installed on the outer cover, outer cover inside is equipped with inverter pallet and fluorescent tube pallet from bottom to top successively, inverter is installed in inverter pallet lower end, cathode fluorescent tube is installed in fluorescent tube pallet upper end by the fluorescent tube installing hole, and the electrode of cathode fluorescent tube is connected with the output of inverter by through wires hole.
The fluorescent tube installing hole is made up of installing hole and liner installing hole.
The fluorescent tube pallet is metal tray, and the fluorescent tube tray upper surface is provided with reflector layer.
Cathode fluorescent tube is for to have two bend pipes with circular arc lead angle at least, and caliber is 2.0mm~6.3mm.
Face shield is the safety glass face shield.
Cold cathode floodlight provided by the invention, beneficial effect is as follows:
1, owing to adopt cathode fluorescent tube as light source, the life-span can reach more than 50,000 hours, was 20~50 times of ordinary incandescent lamp, being 15~20 times of conventional fluorescent lamps pipe, is 5~8 times of Metal halogen lamp, and lamp tube service life is long, colour rendering is good, and colour rendering index can reach 85~95Ra; Adopt high-quality three primary colors fluorescent powder, with under the constant power, light efficiency height, energy savings; The glass of fluorescent tube adopts crown glass; has the ultraviolet function of interception; fluorescent material coating evenly makes 100% UV light be converted to anti-glare lampshade, has solved the difficult coating of conventional fluorescent powder evenly; the problem that UV light leaks; adopt solid mercury meter in the fluorescent tube, mercury content can accurately be controlled, and is that 1.5~3.0mg/ props up; meet international standard, protected environment.
2, traditional ballast driven mode is changed into inverter and drive, driving frequency rises to 50~60KHz by 50HZ, has the advantage of no stroboscopic, flicker free under this high frequency, can prevent visual fatigue; And light source can be because 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, fluorescent tube pallet and inverter pallet are separated into independently space of two in fluorescent tube high temperature chamber and inverter chamber with outer cover inside, and the heat of avoiding fluorescent tube to produce flows in the inverter chamber, has prolonged the service life of inverter.
4, the fluorescent tube pallet adopts metal tray, directly is connected with outer cover, can heat be dispersed in the middle of the air fast, has further reduced the heat of fluorescent tube generation to the influence of inverter, increases the service life of inverter.
5, the design of reflector layer and face shield adopt the safety glass face shield on the fluorescent tube pallet, have utilized the characteristic of safety glass high-transmission rate, have reduced light loss.
6, the fluorescent tube installing hole is designed to installing hole and two kinds of installing holes of liner installing hole, makes fluorescent tube divide two-layer being connected on the fluorescent tube installing hole up and down by the lamp card, adopts the double-layer overlapping mounting means, has reduced volume, has effectively utilized the space, has increased illumination.
7, it is little to have two bend pipe calibers with circular arc lead angle at least, and light source is more concentrated, and illumination is big, has reduced the length of whole fluorescent tube, has enlarged fitting limit.
8, have the cold-starting function, in the time of 0 ℃ brightness unaffected ,-30 ℃ can normally start.
The specific embodiment
As depicted in figs. 1 and 2, the present invention includes outer cover 4 and the face shield 6 that is installed on the outer cover 4, outer cover 4 inside are equipped with inverter pallet 10 and fluorescent tube pallet 8 from bottom to top successively, inverter 5 is installed in inverter pallet 10 lower ends, cathode fluorescent tube 7 is installed in fluorescent tube pallet 8 upper ends by the fluorescent tube installing hole, the electrode of cathode fluorescent tube 7 is connected with the output of inverter 5 by through wires hole 9, the output of inverter 5 passes outer cover 4 and outwards draws interface, directly is connected on 180~240V alternating current.
The fluorescent tube installing hole is made up of installing hole 2 and liner installing hole 3.
Cathode fluorescent tube 7 is divided into two-layer up and down, and one deck is installed on the installing hole 2 by lamp card 1, and another layer is installed on the installing hole 3 that has added liner by lamp card 1.
Fluorescent tube pallet 8 is metal tray, and fluorescent tube pallet 8 upper surfaces are provided with reflector layer.
Cathode fluorescent tube 7 is for to have two bend pipes with circular arc lead angle at least, and caliber is 2.0mm~6.3mm.
Face shield 6 is the safety glass face shield.
