Description

The integral type Down lamp

Technical field

The present invention relates to a kind of lighting, particularly a kind of integral type Down lamp.

Technical background

Down lamp kind in the market is many, but has following shortcoming:

1, lamp bracket and light source are split type mostly, and cost is high, installation is inconvenient, the life-span is short, it is dangerous to use for a long time.The lamp bracket of these Down lamps separates with light source, needs the five metals lamp bracket to fix lamp socket, also the electricity-saving lamp lamp socket need be set, and causes cost too high;

2, the wiring of these Down lamps is also inconvenient, need utilize the binding post wiring, and needs with protective cover it to be protected;

3, fluorescent tube is in running order for a long time, and heat is too concentrated in reflector, causes light efficiency to reduce easily, the problem that light source life shortens;

4, lamp socket and fluorescent tube are installed in the reflector, and reflecting surface can not make full use of;

5, the light source selection is also different, and incandescent lamp, fluorescent lamp, LED lamp etc. are generally arranged.Adopt the lower incandescent lamp of cost as light source, luminous efficiency is lower, probably has only 12%-18% can be converted into luminous energy, and be no more than 1000 hours service life usually; Adopt common hot-cathode fluorescent lamp as light source, owing to use rectifier to drive, can there be stroboscopic phenomenon in fluorescent tube with rectifier 50Hz alternating current per second light on and off 50 times; The service life of fluorescent tube is also shorter, has only about 8000 hours; Poor, the not anti-frequent switch of colour rendering, and, be unfavorable for environmental protection because the mercury content in the power saving fluorescent lamps is difficult to control.And most of LED lamps 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 LED lamp colour rendering index is low, causes light pollution easily; Cause myopia; Particularly the LED lamp is because the blue chip that uses belongs to single wavelength blue light, and long-time the use is prone to make the people to get eye disease.

Summary of the invention

Technical problem to be solved by this invention provides a kind of integral type Down lamp, has that volume is little, the life-span long, efficient, energy-conservation, no stroboscopic, good, the anti-frequent switch of colour rendering, light decay are little, filter UV light, convenient installation.

For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of integral type Down lamp; The face ring and the reflector of this Down lamp are installed together through rivet; Cathode fluorescent tube is fixed on the lamp tube fixing seat through the mode of playing glue; The output of inverter is connected in the electrode of cathode fluorescent tube and the lamp tube fixing seat, and the interior wiring card of self-locking quick patch seat is connected with the input of inverter, and lamp tube fixing seat, fluorescent tube and inverter are done as a wholely to be installed on the reflecting drum through the mode of playing glue.This integral type Down lamp is stuck on the fixing body through snak link.

Light source and lamp bracket integral structure.

Cathode fluorescent tube is a helical lampl.

Below the lamp tube fixing seat and side offers a plurality of heat loss through convection holes that can let in the Lamp cup with the convection current of lamp bracket outer air.

The lamp tube fixing seat cap part is the plane, is provided with self-locking quick patch seat.

In the self-locking quick patch seat wiring card is arranged.

Lamp tube fixing seat is installed in outside the reflector.

The integral type Down lamp is stuck on the fixing body through snak link.

Integral type Down lamp of the present invention, 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; Colour rendering is good, and colour 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 to not injury of human body skin, 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, lamp tube fixing seat, fluorescent tube and inverter adopt integral structure, are installed in as a whole on the reflecting drum, assemble simple, few with material, cost is low.

4, lamp tube fixing seat is installed in outside the reflector, does not have in the reflector and blocks, and makes full use of reflecting surface, improves luminous efficiency.

5, a plurality of heat loss through convection holes that can let in the Lamp cup with the convection current of lamp bracket outer air of offering, below the lamp tube fixing seat and side; Can make in the reflector heat fast the louvre of the louvre through the lamp tube fixing seat lower end and side be dispersed in the middle of the lamp bracket air outward; Reduced the influence of heat, prolonged the service life of Down lamp inverter and fluorescent tube.

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