How to Test LED Dimmable Driver?

As we all know, LED light attenuation is the light weakens during transmission, the quality of LED dimmable driver made by each companies is different, there are light decay also for high-power LED dimmable driver, and it’s have direct relationship with temperature, in fact, mainly depend on the chip, phosphor and packaging technology. The LED luminosity attenuation (including luminous flux attenuation, color change, etc.), is a measure standard of the LED dimmable driver quality, also it is great concern to many LED dimmable driver manufacturers and LED dimmable driver user.

According to the lifespan definition for the LED dimmable driver of the LED industry, the lifetime of LED dimmable driver is the cumulative work time from initial value till light fades to 50% of the original value. This means that the LED still bright when LED dimmable driver achieves its end life time. However, in illumination the light is not allowed if the light output attenuation on its 50%. Typically, indoor lighting the light decay can not greater than 20%, outdoor lighting fades is not allowed greater than 30%.

At present, the white LED light attenuation is one of the most important issues for it’s enter the civilian lighting market. And manufacturers generally tested attenuation in three ways:

a. Visual method: continuously lit LED dimmable driver, observe the brightness and color changes by human eyes.

b. Use light color testing instrument: that during continuously lit LED process, take the LED dimmable driver into the light color test instrument frequently, and record test results, and report test results by EXCEL or other tools.

c. Use professional testing instruments to measure the light fades, that is put the LED dimmable driver in the test equipment, during the continuously lit, the system will have real-time tracking for the LED brightness and color change, automatically generate information sheet.

The Three Most Types of LED Dimmable Driver

Nowadays, the tree most types of LED dimmable driver are Triac LED dimmable driver, 0/1-10V led dimmable driver and PWM LED dimmable driver. Other LED dimmable drivers work by controlling the current, the voltage, the frequency to realize LED dimming function. Let’s look at the details of the three most types of LED dimmable driver.

1.Triac LED Dimmable Driver
Triac LED dimmable driver has long ago been used for incandescent lamps and electricity saving lamps. Nowadays, it is actually the most widely used.
The working principle of Triac LED dimmable driver is that, from a 0-phase AC voltage, waiting for the trigger to be turned on. The advantages of Triac LED dimmable driver is high efficiency and stable performance.

2.0/1-10V LED Dimmable Driver
0/1-10V LED dimmable driver solve the compatible problem between fluorescent lamps and LED lamps successfully. It is wide used with various of capacity dimming system to control the LED ceiling lights, LED down lights, LED panel lights, LED wall washers, LED strip lights and so on.  Euchips’ 0/1-10V LED dimmable driver can realize smooth dimming effect to meet users’ different requirements.

3.PWM LED Dimmable Driver
PWM is the abbreviation for Pulse Width Modulation, it is also be called digital dimming. As we al know, every LED has a rated current, which is the amount of current that needs to flow to get the maximum light output. In a PWM driver, the current is switched at  a high frequency between 0 and the rated output current. This means the LED load is either off or running at its rated current.

What Factors Affect the Lifetime of LED Dimmable Driver?

When LED dimmable driver is designed, the designer should consider the lifetime. What factors affect the lifetime of LED dimmable driver? And How to find some solutions? Only then we can use safely use LED dimmable driver and avoid the damage to the equipments by wrong operation.

LED dimmable driver uses emeralds electrolytic capacitors which directly determines the lifetime of LED dimmable driver. The capacitor interior is predominantly electrolyte. When the seal of capacitor encounters air leak, the electrolyte will flow out with the rapid temperature. For example, when the temperature increases every 10 ℃, the speed of liquid will more rapidly trebled. For example, when at high temperature 100 ℃, the lifetime of electrolytic capacitors is about 10,000 hours. If at 90 ℃, the lifetime of electrolytic capacitors will be 20,000 hours. If at 80 ℃, the lifetime will be 40,000 hours. However, the working temperature of LED dimmable driver is usually about 40 ℃, the temperature of capacitor will be about 80℃， so the lifetime of LED dimmable driver will be 40,000 hours. If the working time is 12 hours every day, the led dimmable driver will be used for 15 years.

If you want to extend the lifetime of LED dimmable driver, you must choose the good quality of electrolyte capacitors.
