Description

Integral type cold-cathode fluorescent Frame lamp

Technical field

The present invention relates to a kind of lighting, particularly a kind of integral type cold-cathode fluorescent Frame lamp.

Background technology

There is following shortcoming in existing T5/T8 Frame lamp:

1. use the inductance rectifier to drive, have stroboscopic phenomenon (50Hz alternating current per second light on and off 50 times), can affect greatly to human eye, the long-time use is easy to cause visual fatigue, and to user's eyesight, particularly teen-age eyesight works the mischief;

2. fluorescent tube is the conventional fluorescent fluorescent tube, and service life is short, has only about 8000 hours, and fluorescent tube is low with the fluorescent material quality, and difficulty reaches 80Ra usually on colour rendering index, and colour rendering is poor;

3. the use rectifier drives, and the frequent perishable driving components and parts of switch the existing picture that glimmers can occur when opening once more, short, often replacing of life-span;

4. mercury content is difficult to control in the fluorescent tube, is unfavorable for environmental protection;

5. when many Frame lamp combinations are installed, need shell;

6. general Frame lamp light loss is very big.

Summary of the invention

Technical problem to be solved by this invention provides a kind of integral type cold-cathode fluorescent Frame lamp, has the long-life, no stroboscopic, and light is stable, and colour rendering is good, effectively vision protection, and the advantage of energy-conserving and environment-protective; And the energy modularity, arbitrarily many combinations.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: integral type cold-cathode fluorescent Frame lamp comprises lamp socket, lampshade and end cap, the lamp socket two sides are respectively equipped with projection and groove, are provided with pipe clamp in the lamp socket, and CCFL is fixed on the lamp socket by pipe clamp;

Inverter is installed in the lamp socket, and CCFL is electrically connected with the output of inverter by high-voltage resistant lead.

The CCFL two ends are fixed by silica gel sheath.

End cap is provided with through hole.

Lampshade inner surface is a striated.

The external diameter scope of CCFL is 2.4mm～8.0mm.

Compared with prior art, integral type cold-cathode fluorescent Frame lamp provided by the invention, beneficial effect is as follows:

1, the lamp socket two sides are provided with projection and groove, are convenient to the light fixture modularity, arbitrarily many Frame lamp combinations.

2, the Transparent lamp shade inner surface is a striated, can the light that fluorescent tube sends be disperseed, and prevents dazzle;

3, end cap is provided with through hole, can hang with rope, puts just to install.

4, owing to adopt CCFL, the life-span can reach more than 50,000 hours, and higher 5 times than T5 lamp tube service life, colour rendering index can reach 85～90Ra, and colour rendering is good; Because it is anti-UV that cathode fluorescent tube adopts glass-tube, nothing is ultraviolet, is applicable to long-time illumination, to not injury of human body skin, changes in the past the situation of president's spot under illumination for a long time;

Mercury content can accurately be controlled in the cathode fluorescent tube, and the mercury content of single tubes is 30% of a T5 fluorescent tube mercury content, meets the environmental requirement of European Union;

5, fluorescent tube drive to adopt the high-frequency drive mode of 45KHz to 55KHz, and human eye perceives is less than the variation of light, effective vision protection;

Adopt big current drives, whole light fixture has the fluorescent tube parameter automatic optimization, has very high photoelectric transformation efficiency, and light efficiency is more than the one-level efficiency, and greater than 69Lm/w, energy conversion efficiency is higher than electron rectifier efficient 5% ~ 10% greater than 90%;

Inverter drives fluorescent tube indirectly, rather than directly drives fluorescent tube as rectifier by power plant by step-up transformer, and switch can not damage because of frequent switch, and the switch number of times is more than 100,000 times.

6, under same light flux situation, the present invention can effectively improve 30% to 40% illumination, and whole light fixture can detect the abnormality of fluorescent tube automatically, starts defencive function, turn-offs output circuit, and is safe and reliable.
