Excellent performance of the LED industry is generally considered ideal for the fourth-generation light source, and the source of LED fluorescent tube is in high luminous efficiency, lifetime, response time, and are better than incandescent, fluorescent and other traditional sources environmental protection .
LED fluorescent tube efficiency has increased annually, and has reached the general lighting applications. From 2010, the latest published results, the current white LED luminous efficiency of its laboratory to 200lm / w, commercial chips to reach 160lm / w, and plans volume production in 2013 200lm / w of the LED. LED fluorescent tube package module light efficiency of 160lm / w mind through the process from light to light loss of about 50%, and light output of light performance to achieve 90lm / w. It is more than the current fluorescent 60-80lm / w light efficiency, and far more than the incandescent 10-15lm / w efficiency. Effect from the light on, LED fluorescent tube to replace traditional light sources has reached the standard.
Currently commercialized products have been reflected in the luminous efficiency of LED's advantages, such as the use of screw-type base LED fluorescent tube design, which can be used to replace traditional incandescent bulbs, and do not need to change the existing lamp and line. According to the size and bayonet, the bulb size can be classified into E26 and E17-type, and 4W LED bulbs can replace 25W incandescent bulbs, 6W LED bulb can replace 40W incandescent bulbs, 10W LED bulbs can replace 60W incandescent bulbs.
As to technology, LED fluorescent tube source instead of the traditional efficiency has been achieved the requirements of the current constraints of LED fluorescent tube is a major factor in the rapid spread of its high cost. In future, the main direction of development of LED lighting, should not be lm / w, represented by the technology upgrade, but It is represented by the cost reduction.
