How to measure the life of LED lights, and how long is the life of LED lights

Life expectancy prediction formula: MTBF = hours that have been tested * ln (the decimal value of the white fraction ratio of the end of the life test) ln (1 - the percentage of attenuation of the life test) According to the above formula, it is obtained:

3528h241w estimated life = 5000h*ln (

Note: This part is about 45 degrees at IF=20mA, TJ about 55 Ts, and Ambient Temperature: 25 degrees.

The life span of LEDs is an absolute environment in theory, and the actual use can only be estimated by simulating deterioration conditions due to excessive external influences. There are many reasons for the uncontrollable environment after the actual application of LED, such as the stability of the driving current, the impact of the instantaneous current, the environment and the heat dissipation materials used, etc., all of which greatly reduce the life of the LED. In terms of surge and current pulse, we use buffering and instantaneous changes to absorb the current to protect the LED from impact, so that the LED is well protected, and if necessary, we can learn together ().

The life of LED lamp beads is long, most of them can be more than 10 years (with light decay).

However, LED lamps are the most prone to breakage is the controller, and it is more common for regular products to fail in two or three years. Miscellaneous products go bad or flicker after a few months.

My family is using 3 to 5 years.

<> has a lifespan of 50,000-100,000 hours without damage. Generally speaking, it is written that 50,000-100,000 hours, but in practical applications it will not be so high. On the one hand, the product quality of some LED companies is not too high, and there is that LED is generally integrated in a large number of products and used in a product, and a broken product is equivalent to a broken product.

Hello dear! The life span of LED lights is generally years old. Generally, there is no problem with 3-5 years of use.

The theoretical life of LED lights is 100,000 hours, and if calculated according to the theoretical life, the continuous light can be used for 11 years. However, this is the highest value in an ideal state and is impossible to achieve in normal use. In real life, the service life of LEDs is also related to current, brightness, material, etc.

Its service life is similar to that of the barrel raw material, it is determined not by the parts that have the longest life, but by the time that the internal service life is the shortest. 1. When using LED lamps, try not to switch on and off frequently. Although LED lights are durable, frequent switching on and off LED lights will still affect the service life of the internal components of LED lights, thus affecting the service life of LED lights.

Special attention should also be paid to the environment in which the ED lights are used. Generally speaking, LED luminaires are not suitable for working in humid environments (except for LED luminaires with moisture-resistant performance), and their internal electronic components are prone to moisture, resulting in damage to LED luminaires or leakage and short circuits. 2. When cleaning the LED light, remember not to change its structure or replace parts at will.

After cleaning, it should be installed as is, and its parts should not be omitted or installed by mistake. When cleaning, do not wash with water, but wipe with a dry cloth. Do not wipe with a damp cloth immediately after turning on the light, it is easy to be dangerous.

The country is paying more and more attention to lighting energy conservation and environmental protection issues, and has been vigorously promoting the use of LED lamps. Obviously, as long as the cost of LED lights decreases with the continuous improvement of LED technology. Energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps.

Next, PCHOUSE will introduce to you how long the life of LED lights is.

1. First of all, the life of LED lamps and lanterns is generally in 100,000 hours, and LED lamps must have a certain amount of power, the greater the power, the higher the heat dissipation requirements, if the heat dissipation effect is not good, it will directly affect the life of LED. 2. LED In the lighting industry, the number of LED life values that we are more common can reach 30,000 to 50,000 hours. The life standard of incandescent lamps is generally 1,000 hours, and most LED lamps are used in the home, and its most important reason is energy saving and advantages.
