There are lots of manufacturers producing the LED lights, there are many different production environment and processes, then as consumers when purchasing LED energy-saving lamps, how to judge the quality of the LED light?

I will teach you to judge whether the quality of LED light is good or bad, these are lessons learned in many ways.

First, inspect the overall ” the Power Factor of the LED energy-saving lamps”: the power factor of the LED light is low， indicating that the drive power, circuit design is not good, it will greatly reduce the lamp life, for the low power factor, even if using better lighting lamp beads，the life is not long.

Second, inspect the “lamp cooling conditions – materials, structures”: the cooling of the LED light is also very important, compare the lamps of the same power factor and lamp beads of the same quality, if the cooling condition is not good, when the light bead work at high temperatures, the light fades will be great, lamp life will be reduced.

Third, inspect the ” the quality of the light bead “: the quality of the light bead depends on the quality of the LED chip and packaging technologies.

Fourth, inspect the drive power the LED energy-saving lamps use, take the LED tube light for example，relative to other parts of the lamp, the life expectancy the of power is much shorter, the life of the power affects the overall life of the lamp, theoretical life the lamp beads is 5-10 million hours, while the life of the power is between 0.2 and 3 million hours，the design of the power and the material selection will determine the power of life.

Fifth, inspect the luminous efficiency: the same power of the lamp beads, the higher light efficiency is, the brighter the brightness, the same illumination, the smaller the power consumption，the more energy efficient，which is particularly evident on the performance of the LED tube light.

Six, check up the power efficiency, the higher，the better, higher, indicating that the power consumption of the power itself is smaller, the greater the power output.

Seventh, make sure if compliance with safety standards? Safety standards of China’s LED lighting has been introduced, choosing the LED tube light that is the main LED light indoor and the LED flood light that is enjoys a great popularity as the decorative light outside as the required safety standards.

Eighth, whether the working fine of the LED light, we firmly believe that the product quality control of an LED energy-saving lamps enterprise significantly determines his attitude to quality.

The LED tunnel light relying on its long life, low power consumption, etc., has already been large-scale used in the field of the tunnel lighting, because large-scale used in tunnel that is limited arrange, the impact of current and problem of heat dissipation, which directly affect the maintenance of the LED tunnel light. How to minimize the damage to the LED tunnel light?

First of all， analyze the causes of damage to the LED tunnel light.
The instability of the LED drive power and damage to the device is the main reason

Unstable large current impacting the drive power leads to that the power occurs to transient overcurrent, resulting in damage to the weld lines, which will spread to the surrounding components of the weld lines, such as some poor the sealing material of the LED tunnel light may thus invalid. Considering the design of the drive power, we should try to consider the impact of a large current is generated, designing the unique fault protection measures is to ensure the circuit reliability. Such as use overvoltage overcurrent to protect the components of the LED tunnel light.

The heat dissipation problem of the LED Tunnel Light can lead to premature failure of lamps.

Use PPTC resistor, the heat generated in the process of the current through will cut off the path the conductive particles form, so that the formation of temperature reduction effect, excluding temperature, the overheat protection of the circuit can be realized，while the circuit can automatically start and response to ensure the normal lighting.

One, It is easy to maintain for the LED flood light, the LED flood light attached the scale plate lamps is easy to adjust the illumination angle.

Two, the LED flood lights are two kinds of symmetric and asymmetric light distribution options，the glare control effect is good; lamps, electrical integration, beautiful and compact design, easy to install; the rating of the dust and waterproof is at least IP65.

Three, the supply voltage of the LED flood light is 220V, 110V, 24V or 12V.

Four,there are the external control and internal control modes used for LED flood light. Internal control without an external controller, built-in Multi-Mode (up to 6 kinds), the external control have to be configured external control to achieve color change. Currently, the majority of the external control is applied in the market.

Five, the irradiation distance of the LED flood lights is generally 5 ~ 60m, especially for billboards effect lighting, landscape building，floodlighting, squares， tennis courts, car parks and other green landscape lighting; also be used for lighting landscape and indoor local (eg wall displays brush color); also for the medical, cultural and other specialized facilities, bars, discos and other entertainment atmosphere lighting.

Nowadays, the LED flood lights because of the octahedral point light irradiation range and gorgeous colors and soft lighting enjoys a great popularity as the outdoor decorative lighting, but how to choose a good LED flood lighting is our concern

1.The LED flood light (MCD) determines the price level. Shall comply with Laser Class Class Ⅰ standards.

2, the antistatic ability of the LED flood light is strong, its life is long. Usually the static ability of the LED that is more than 700V can be used for LED lighting.

3, The closer the wavelength of the light the LED flood light emit is at 383mm to 780mm, the better the showing results， It is difficult to produce pure colors for those manufacturers having no LED spectral separation device.

4, the LED flood light whose leakage current is large, the life is short, the prices is low.

5, the LED light-emitting angle is different，its light angle is not the same. The prices of the Special light-emitting angle is higher. Such as the all diffusion angle， higher prices.

6, the key is life, life is determined by the light fades. Light decay, long life, long life, high price.

7, the luminous body of the LED flood light is chips, the prices of different chips vary widely. The Japanese and the American chips is expensive, the prices of the chip generally made ​​in Taiwan is lower than Japan and the U.S..

8, the chip size the quality of the big LED chip is better than small. The Chip size is proportional to the price.
