Top Four Main Steps to Choose Functional LED Tube Light
LED lamp with its incomparable advantages gradually replaced the traditional white light and entered the common families. For many savvy consumers, choosing a good LED tube light is very important. Now let me tell you some details about this. Compared with the other lights, LED tube light has very outstanding advantages: Energy saving, long-time using, Green environmental protecting. However, the difference in quality of LED tube light is very large. Ordinary people don't know how to choose a better one. So, How to choose the LED tube light?
Firstly, with Low power, the usage of drive power supply, circuit design is bad, Will greatly reduce the make of T8 LED tube light of using. This is because, LED tube light will never use for long time with low ?power factor.??Usually, LED lamps power factor above 0.85 is required. Whose power lower than 0.5, is belongs to the unqualified products. Not only the time for using is shorter, but also the actual consumption power around a time is higher than the nominal. That is to say, it has no electricity at all. This is why the LED tube light needs equipped with high quality and high efficiency drive power.???If the consumers have no "power factor" to used to test the LED tube lights of power factor. There is another way, to detect two nominal powers of the same similar products with "current”. The greater is the current, the more consumption. At the same time, the unstable current is disadvantage for the LED tube light.
Secondly, detect the LED tube light of the cooling conditions, materials, and structures. it is also very important to The LED tube light's cooling condition. Because without a good cooling condition, LED tube light works under high temperature, service time will be reduced.?Even in the same power and same quality of the light. Nowadays, the LED tube light mainly use dissipation material to rejection of heat, such as copper, aluminum and PC. The thermal conductivity of copper is better than aluminum, while the thermal conductivity of the aluminum is better than PC. Now commonly use is aluminum radiator material, Insert the aluminum is the best, while Car aluminums the better and the worst is cast aluminum.??You must deal with the insulation circuit and power supply problems if you adopt the method of air convection to the cooling.?If not, LED tube light is prone to a short circuit when working in a wet environment. It might cause some safety accident.
Third, the quality of LED tube light's bead depends on the quality of chip and the technology of packaging. There are three camps of chip brand in the world: First, the manufacturers represented by Europe and the United States and Japan, mainly including Cree, Os-ram, daily chemical, Toyota, etc;??The second is that the manufacturers represented by the United States, South Korea, China Taiwan, mainly including XuMing, Seoul, wafer, Thai valley, wide grain and the new century, etc;?Third, the manufacturers represented by domestic companies, there are three main Ann, Di Yuan, Blu-ray, Shimming core and the Road, etc. The quality of chip decided to the brightness of the lamp bead and droop. As a good light, not only has high brightness, but the droop is also small.
Fourth, the use of the power supply time, relative to other parts of the lamps and lanterns is shorter, the use of the power supply time influence the overall use of lamps and lanterns. Lamp beads using in the theory of time is 5-100000 hours, when the power supply used in 0.2 30000 hours, the usage of the power design and material decided the power supply time.??
In a word, A good quality LED tube light, is a perfectly combination of high quality of drive power supply, good conditions of heat dissipation and high quality of lamp bead, conform to safety standards. A LED tube light is not a qualified product, if only emphasis on either side
