Description

The cold cathode Grating jetting lamp

Technical field

The utility model relates to a kind of light fixture, especially a kind of cold cathode Grating jetting lamp.

Background technology

The most Metal halogen lamps that adopt of at present domestic Grating jetting lamp are as light source, though this light source light efficiency height, colour rendering are relatively good, but because the restriction of present material and technology, under the condition of considering its brightness and volume, the life-span is shorter, generally has only about 8000 hours, and it can not thermal starting, can not be with driveing with the pass, light source restarts that generally all will cool off could be for the second time luminous after 3 minutes, and light decay will occur after 3000-4000 hour.Very disadvantageous during commercial situations that these shortcomings are long in lighting hours, switch is frequent.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of cold cathode Grating jetting lamp, overcome the shortcoming of the used Metal halogen lamp of existing Grating jetting lamp as light source, volume is little, the life-span is long, energy-efficient, no stroboscopic, good, the anti-frequent switch of colour rendering, light decay are little.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cold cathode Grating jetting lamp, comprise shell, shell is provided with panel, a plurality of cold cathode energy-saving lamps are installed in the enclosure, snap ring is fixed on the both sides of cold cathode energy-saving lamp by rotary screw, and reflection Lamp cup upper end is installed on the cold cathode energy-saving lamp, and the reflection Lamp cup is fixed on the snap ring by turn.

In the cold cathode energy-saving lamp, lamp socket is installed in the shell, and inverter is installed in the lamp socket, and the cold cathode spiral fluorescent tube is installed on the lamp socket by clamp, and the electrode of cold cathode spiral fluorescent tube is connected with the output of inverter.

The caliber of cold cathode spiral fluorescent tube is 2.0mm～6.3mm.

The cold cathode Grating jetting lamp that the utility model provides, beneficial effect is as follows:

1, owing to replace traditional Metal halogen lamp as light source with cold cathode energy-saving lamp, the life-span can reach more than 50,000 hours, and the life-span is long, colour rendering 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, can effectively stop ultraviolet light in the light to the human injury, has overcome the shortcoming of the used Metal halogen lamp of Grating jetting lamp as light source.

2, adopt the cold cathode spiral fluorescent tube, make the lamp body structure compactness, under illumination of the same race, volume is little, has enlarged the scope of application.

3, cold cathode spiral fluorescent tube fluorescent material coating evenly makes 100% UV light be converted to anti-dazzle, has solved the difficult coating of conventional fluorescent powder evenly, the problem that UV light leaks.

4, 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 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.

5, adopt solid mercury meter in the cold cathode spiral fluorescent tube, mercury content can accurately be controlled, and is that 1.5～3.0mg/ props up, and meets international standard, has protected environment.

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

7, reflection Lamp cup upper end is installed on the cold cathode energy-saving lamp, the reflection Lamp cup cooperates integrated light source of formation with cold cathode energy-saving lamp, integrated light source is fixed on the snap ring by turn, the reflection Lamp cup can be thrown light on to the want article or the environment that embody according to customer demand at 180 ° of range regulation direction of illuminations.
