Maintenance method of LED bulb
LED bulb is now used very much, LED bulb not only stable light source, at the same time, the service life of LED bulb is very long, many people like it very much. Now there are many types of LED bulbs in the market, but many people are not very clear about how to repair when the LED bulb is broken, resulting in the LED bulb replacement frequency greatly increased. Next, Bihua lighting editor will introduce the maintenance method of LED bulb to you, hoping to help you. If we encounter LED bulb broken again, we can do better repair LED bulb by ourselves.
When the light is not on, make sure the circuit is OK first. If it is a new light, you should use an electric pen to measure, or install an incandescent lamp to see if there is voltage in the circuit. After confirming that the circuit is OK, you can start the following maintenance.
1. Actuator problem
If the light doesn't work, it's probably the driver's problem. Light emitting diodes (LEDs) have high requirements for current and voltage, which can not be turned on normally when the current and voltage are too large or too small. Therefore, constant current drivers, rectifiers, voltage reducers and other devices are needed
Keep using.
If the lamp does not light up after turning on the lamp, the driver should be considered first. A new drive can be purchased for replacement.
2. Solutions for LED brightness darkening
This problem should be solved together with a problem. This may be the case if the light is dim or not.
3. Lamp bead problem
LED lamp beads are divided into strings. The beads on each string are connected in series, and the strings are in parallel.
Therefore, if a lamp bead on this string is burned, it will cause the string of lamp beads to be out of light. If each string has a lamp bead burned down, it will cause the whole lamp to be not on. If there is a lamp bead burned out in each string, the capacitance or resistance on the driver should be considered. The burned lamp beads and normal lamp beads can be seen from the appearance. There is a black dot in the middle of the burned lamp beads, which can not be erased.

How to solve the problem of heat dissipation for LED panel lamp?
In the LED panel lamp, there are three basic stages of heat transfer, from integrated chip to epitaxy, from packaging base steel plate to heat sink or shell. At present, the technical problem of LED heat dissipation is that led nodes are limited by temperature. High temperature will cause led integrated chip, luminous powder, packaging epoxy resin service life is reduced. In order to keep the advantages of high efficiency and long life of LED, the junction temperature of LED must be controlled.
