Practical guide to LED lamp repair
Experience in LED lamp repair
My collection of LED lights starts in October 2012. It was then that I first purchased a 5W R50 Jazzway lamp. Then there were many different instances of lamps from Jazzway, Navigator, BBK, lamps from Aliexpress.
It is clear that lamps differ in quality from different manufacturers and from one manufacturer in different price categories - lamp lines.
At the beginning of 2013, I ordered Jazzway lamps in Krasnoyarsk, the ECO R50 line. Because I have 80 percent R50 at home, some of the R50 ECO bulbs started to fail in 2015. Of course, it is very disappointing when you pay 150 rubles for a lamp, count on 30-50 thousand hours of work, and the lamp breaks after 1.5-2 years of work in a gentle mode. But in most cases, the matter is rectified.
In the aforementioned Jazzway R50 ECO 3.5W, the problem is always identical – a faulty LED. I've had 3 of these in the last year. The lamp design is built on 24 SMD3014 LEDs (denomination 0.1W). Apparently, LEDs work in an uncomfortable mode (without an aluminum radiator), while they are overclocked above their nominal value.
Symptoms of a burned-out LED:
1. The lamp goes into lighting mode.
2. The lamp stops working, but there is no visible damage to the lamp, there is also no smell of burning.
3. The LED on the board has a darkened appearance or traces of burnout.
How to treat:
1. First you need to remove the bulb from the lamp. Since most diffusers are now made of polycarbonate, the removal of the diffuser should not cause difficulties (of course, if the diffuser is not soldered into the lamp body). To remove the diffuser, you will need a simple indicator screwdriver.
2. Since usually on an LED board all LEDs are connected in series, the failure of one of the LEDs leads to an automatic circuit break and compliance with the loss of lamp performance. In the second step, you need to find a faulty LED. If you can not visually see the burnt-out LED, then checking the LEDs is carried out using a multimeter. (see photo).
- working LED - check with a multimeter.
- defective LED.
3. After detecting a faulty LED, it is necessary to remove the LEDs from the board and replace the LED with a new one, or to make soldering of the LED contacts. Close the chain.
- contact cleaning
4. After soldering, the lamp should work.
- Rations.
- lamp inspection
Replacement of the condenser
The most common cause of failure is the burnout of a cheap Chinese condenser. The easiest way out of this situation is to replace it with a new capacitor, besides this is a cheap detail. Subscribe to our YouTube channel www.youtube.com/channel/UCXd71u0w04qcwk32c8kY2BA/videos
P.S. And remember, just changing our consumption – together we change the world!
