Abstract
A cold-cathode T2 frame lamp is characterized in that an inverter is mounted in a lamp holder, and a cold cathode lamp tube mounted on the lamp holder is electrically connected with an output end of the inverter via a high-voltage resistant lead. Compared with the prior art, the cold-cathode T2 frame lamp has long service life which is longer than 50,000 hours and six times of that of a T5 lamp, is fine in color rendering property as the color rendering index can be 85-90Ra, is free of ultraviolet and suitable for long-term illumination, is harmless to human skin and prevents the human skin from freckling when people are irradiated with light for a long time. Human eyes can not feel change of light, thereby effectively protecting eyesight. In addition, abnormal conditions of the lamp tube can be detected automatically, and the lamp can start a protection function to cut off output circuits safely and reliably. Therefore, the cold-cathode T2 frame lamp is particularly suitable for illumination places such as classrooms in schools and marketplaces.
Description
Technical field
The utility model relates to a kind of illuminating lamp, particularly a kind of T2 Frame lamp that adopts CCFL.
Background technology
There is following shortcoming in existing T5/T8 Frame lamp: use the inductance rectifier to drive, have stroboscopic phenomenon, 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; Fluorescent tube adopts tungsten filament as electrode, and is volatile in the course of work, and service life is short, generally has only about 8000 hours; Tube diameter is thick, and generally greater than 16mm, it is bigger to take up room, and inner fluorescent tube powder coating consumption is many; Used fluorescent material quality is low, and light decay is fast, and luminous efficiency is low, and generally about 60lm/W, colour rendering index is difficult to reach 80Ra usually, and colour rendering is poor; Mercury content height in the pipe, generally greater than 10mg, the fluorescent tube discarded object is easy to environment is polluted; Use the inductance rectifier to drive, the frequent fragile driving components and parts of switch need preheating, and occur scintillation easily during unlatching, and the life-span is short, needs often to change; Overall weight is heavier.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cold cathode T2 Frame lamp, can have the long-life, and no stroboscopic, colour rendering is good, the advantage of effectively vision protection, and energy-conserving and environment-protective.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cold cathode T2 Frame lamp, and inverter is installed in the lamp bracket, and CCFL is installed on the lamp bracket, and CCFL is electrically connected with the output of inverter by high-voltage resistant lead.
In the described lamp bracket, support is connected with the support upper casing with buckle by support upper casing button, and the retaining head is installed in support and support upper casing two ends.
Described CCFL is by the rack-mount shell of plastics pipe clamp.
Described inverter is installed between support and the support upper casing.
Described cold-cathode lamp external diameter of pipe scope is 5-7mm.
The described cold-cathode lamp external diameter of pipe of this patent is 6.3mm.
Compared with prior art, a kind of cold cathode T2 Frame lamp that the utility model provides, beneficial effect is as follows:
1, owing to adopt CCFL, the life-span can reach more than 50,000 hours, improved 5 times than T5 lamp tube service life, and colour rendering index can reach 85～90Ra, and colour rendering is good;
2, be anti-UV owing to cathode fluorescent tube adopts glass-tube, nothing is ultraviolet, is applicable to long-time illumination, and human body skin is not injured, and changes in the past the situation of president's spot under illumination for a long time;
3, adopt the high-frequency drive mode of 45KHz to 55KHz, human eye perceives is less than the variation of light, effective vision protection;
4, 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, the CCFL that adopts cooperates the work of high-efficiency inversion device, adopts big current drives, and whole light fixture has the fluorescent tube parameter automatic optimization, has very high photoelectric transformation efficiency, light efficiency is (〉 69Lm/w more than the one-level efficiency), energy conversion efficiency is higher than electron rectifier efficient 5% ~ 10% greater than 90%;
6, whole lamp can detect the abnormality of fluorescent tube automatically, starts defencive function, turn-offs output circuit, and is safe and reliable.
