Description

The cold cathode Ceiling light

Technical field

The utility model relates to a kind of Ceiling light, especially a kind of cold cathode Ceiling light.

Background technology

Domestic existing Ceiling light generally adopts LED lamp or Metal halogen lamp as light source, and Metal halogen lamp is because the restriction of material and technology at present, and under the condition of considering its brightness and volume, the life-span is short, can not thermal starting, and light decay is big.And the LED lamp is as present new type light source, most of products in real the application owing to there are problems such as heat radiation, power utilization, luminous efficiency, light decay, life-span is difficult to reach established standards, and, cause light pollution easily because the white LED lamp colour rendering index is low, cause myopia, particularly white LED lamp is because the blue chip that uses, belong to single wavelength blue light, long-time use easily makes the people get eye disease, therefore present most LED lamps and be not suitable for room lighting.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of cold cathode Ceiling light; adopt cathode fluorescent tube as light source; overcome the shortcoming of existing Ceiling light, long service life, little, the anti-frequent switch of light decay, no stroboscopic, vision protection, easy for installation.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cold cathode Ceiling light, comprise lamp bracket, the lamp bracket both sides are equipped with spring, Reflecting lamp cup is installed on the lamp bracket, cathode fluorescent tube is installed on the lamp socket by the clamp of lamp socket lower end, and the electrode of cathode fluorescent tube is connected with the output of inverter in the lamp socket, and lamp socket is installed on the Reflecting lamp cup.

Reflecting lamp cup is installed on the lamp bracket by circle rotation boss.

Reflecting lamp cup is the square Lamp cup.

Cathode fluorescent tube is the cold cathode spiral fluorescent tube.

Offer a plurality of louvres on the lamp socket.

The quantity of louvre is no less than 4.

The cold cathode Ceiling light that the utility model provides, beneficial effect is as follows:

1, owing to adopt cathode fluorescent tube as light source, the life-span is long, and can reach more than 50,000 hours service life, is 15～20 times of conventional fluorescent lamps pipe, is 5～8 times of Metal halogen lamp; Adopt high-quality three primary colors fluorescent powder, with under the constant power, light efficiency height, energy savings; Colour rendering is good, and colour rendering index can reach 85～95Ra; 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, can directly the utility model be installed on the ceiling by spring, install simple and convenient, attractive in appearance.

3, 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.

4, Reflecting lamp cup is installed on the lamp bracket by circle rotation boss, and Reflecting lamp cup can 180 ° of rotations, conveniently adjusting direction of illumination.

5, Reflecting lamp cup is designed to square, compares with the Reflecting lamp cup of existing vertical shape, has increased reflective surface area, improves luminous efficient.

6, a plurality of louvres of offering on the lamp socket, the heat that inverter is produced is dispersed in the middle of the air fast, has reduced the influence of heat to inverter, has prolonged the service life of inverter.

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