Eye -eye LED platform lamp bead

Hello everyone, I am Xiaobian Rong, today, let ’s introduce the problem of the life of LED lamp beads LED lamp beads. The following is the summary of Sister Rong’ s summary of this issue and related issues. Let ’s take a look.

Article Catalog Navigation:

1. I bought LED eye protection lamp beads on the Internet. There are only 5 other white lights that are dark. Is it broken? How to replace the beads 4. How big is the resistance on the LED table lamp beadplate?

I bought LED eye protection light beads on the Internet. There are only 5 other white lights. The non -bright LED has failed.

LED eye protection lamp bead life

Theoretically, the life of LED lamps is generally 100,000 hours, and LEDs must have a certain power to make lamps. The greater the power, the higher the heat dissipation requirements. If the effect is not good, it will directly affect the life of LED.

And the life of LED has a lot to do with current, brightness, and materials. When the LED light is used for more than 1,000 hours, light failure will appear, which means that its brightness is not as bright as the first.

LED table lamp beads are replaced

First of all, there is a kind of professional heating platform, which is a flat steel plate. There is a type of heating device underneath. It is best to have temperature control functions.

Fold the lamp and remove the lower light plate.

Then turn on the heating table for about 250 degrees, and heat the lamp plate on it. After the tin melters it, you can remove the lamp beads with a mule.

Then clean the lamp plate clean tin planting, put on the lamp beads melted, remove the lamp board and wait for the cold.

LED table lamp beadboard has two types of lamp beads. Different categories have different resistors.

1 is the LED lamp (such as red, yellow, orange, etc.) that can be lit at about 2V: 12V: 470 Euros 12V: 680 Euros

Second is the LED light of about 3V (such as blue, green, green, green , White, etc.): 12V: 390 Euro car 12V: 470 Euros

The parameters of the resistance generally have two, resistance R and power P. R \u003d (u-ULED)/ILED, the standard voltage of USB is DC5V, so R \u003d (5-ULED)/ILED ULED, the positive direction voltage of the lamp beads. ILED, the positive direction current of the lamp beads. Now there are many types of LEDs, different colors, and general currents. The resistance of the resistance affects the current, and then affects the brightness of the lamp beads, but as long as it does not exceed the forward maximum current, it can be used, but the brightness may be different, so the selection range is relatively large. The above is the answer to the use of LED lamp beads LED lamp beads LED lamp beads and related issues of LED lamp beads, I hope it is useful to you [Responsible Editor: Rong Sister]
