1. what is the LED tubelight?
A: LED tube light follows the appearance of traditional tube light's size, no starter and ballast, quick start, no flicker, not easy to get visual fatigue. Super bright white LED light is used as the source of LED tube light, the shell is made of acrylic / aluminum alloy. PC tube can be used for LED cover. LED tube light is the same with the traditional tube light in size and diameter, the length contains: 60cm, 120cm and 150cm, the power contains: 10W, 16W and 20W, and 20W traditional tube light's (ballast contained) actual power consumption is about 53W , 40W traditional tube light's (ballast contained) actual power consumption is about 68W.
2. GL warm tips on tje three factors of LED lamps and lanterns.
A: technological elements: import chip lamp bead + constant-current source drive + cooling encapsulation technology;
Price elements: high quality high price and low price surely inevitable high lights failure;
Choose elements: flagship version for the long hours business lighting, cost-effective light for the short time family lighting;
3. LED tube lights' life problem?
A: LED tube light'life means the time of LED luminous beads' brightness reducing to 50%, imported chip lamp bead's time is general 70,000 hours, damaging life is 100,000 hours; The whole life of Led light includes the life of LED bead lumen and the life of drive system, high quality LED light's whole life can reach 20,000 to 30,000 hours, while the non-genuine light can not guarantee its life.
4. Does LED tube light have zero light failure?
A: No, light failure is inevitable, zero light failure does not exist, but the degree of light failure is different.
5. Why does high-quality LED lighting is slightly more expensive?
A: The biggest advantage of LED lights is high energy-saving and durability, energy-saving is the essential characteristic of the chip led, durability manily means the control of light decline. The key factors influence light failure are as follwing: first, a high quality chip with a small decline is of high price of light, a low-quality chip with high light decline is of low price; Then, it is the constant current driver, led light is sensitive to the heat of light-emitting diode chip, so we must use the constant current driver to control the chip heating degree, so as to control the light decline, however a high-quality real constant current drive power has a much higher price; Thirdly, it is the packaging process, the cooling requirements are particularly high, the production craftsmanship is also very important. All of these three factors make the good quality of a LED light, but also offer its high prices, that is the so-called high-quality, high price, low price high light failure.
6. How to control the junction temperature?
A: GL LED light uses aluminum cooling fin as LED light shell, this kind of unique design will reduce the junction temperature as low as possible.
