Simple said the LED tube light is actually family in daily life with the lighting lamps and lanterns (bedroom, sitting room, balcony, etc.), only the light source is no longer the traditional energy-saving light bulbs, but the use of LED lighting, LED downlight, choice is no longer as easy as the traditional energy-saving lamps, incandescent lamp), so consider factors is also different, so, how should we choose and buy the LED tube light?
Cooling speed determines the LED tube light, the light failure degree and the length of life, the radiator is too small can make the heat accumulation within the light source, and the lamp bead work long time under high temperature condition, the light failure quickly, the service life is very short, so when choosing the LED tube light, suggest you had better choose made of aluminum shell, because of the aluminum heat dissipation coefficient is higher, heat dissipation is more fast, to ensure the normal order of the LED tube light illumination.
2. Drive power supply.
The power supply is also called transformer, and the quality of the transformer determines the life of the whole lamp. The lamp bead can be used for more than 50,000 hours, but if the transformer is broken, the whole lamp will not be able to shine.
Transformer used in the design of electronic components, determines the efficiency of transformer, power factor, stability, temperature rise, the service life, so when buying LED tube light, it is recommended that you'd better choose wide voltage driver, it can guarantee the stability of output current voltage, ensuring that the LED tube light in the security and stability in the process of use.
Light bulb quality.
Buy the LED tube light in addition to the need to consider the material and driving power, emphasis must also consider its quality lamp bead, light bead lamp lighting effects depends on the quality, packaging process affects the quality of lamp bead, heat dissipation and other key factors.
At present, the LED light bead chips sold in the market have domestic and imported products. Generally different brands, different prices and different lighting effects suggest that you should be careful enough to buy them.
Ps: recently someone asked the difference between a tube lamp and a light bulb.
Answer: normally, the tube lamp is used as ordinary illumination, it asks to provide ambient light can.
A tube lamp means a light that goes down.
Shoot the light is to provide local lighting, it is required to provide local scope, used for close-up lighting, increase the light out an object or objects (common have shopping malls, clothing stores, mobile phone stores, etc.).
Now many when the family is decorated, commonly used sitting room of small size tube light, usually used to wash the wall lamp, increase the luminosity of sitting room wall, hallway or corridor balcony, etc., with the tube light is for general illumination.
