There is no doubt that the good quality of the LED flood lights is the core of business, no matter you are the led flood light wholesalers, contractor of projects, or the B2C seller in Amazon or eBay, it is a big problem when the clients’ complaint to you that the flood light you sold to them are flashing, they will return the led flood light to you and ask you to refund, maybe this is a disaster of your business.
When you find the led flood light flashing, You need to make clear the situation as below:
is it a new flood light or used for a long time? Check the flicker frequency, it will start to flash when you open the switch or only flash at a special time? whether all of the same batches led flood lights you buy all-flash in the same situation?
Before we answer Why the outdoor led flood light is flashing, you need to know, no matter How good the good quality of the led flood light is, it also can go out, even the new ones you just opened.
Normally, there are many problems to make the led flood light flashing, here are several main reasons to cause it.
1, check the connections, the loose connections and dirty connections will make the contact poor, so, try to reconnect the wires and tighten the screws.
2, the problem of the driver, when you find the outdoor led flood light flashing, you can open the box of the driver, and check if the driver is OK, and then find a good quality driver with the same parameters to replace it, and reopen the flood light to check if it works or not.
The main problem of the LED driver damage is the high temperature of the flood light. Because of the led flood light usually used in outdoor, it needs to be IP65, even IP68 waterproof, the high quality sealed to make the Poor heat dissipation, especially for the high power led flood lights, but many led flood lights manufacturers use the low-quality drivers to save the cost and sell at a low price to attract the clients.
3, after you replace the new LED Driver, the flood light is still flashing, Please check the led chips of the lamp. in the SMD flood light, if the LED Chips were burned, you can find there are many dark dots in the LED Chips.
There are two problems to make the LED Chips fail, one is the high temperature of the led flood light and poor heat sinking system to make the led chips overheating, the other one is the size of the LED Chips, there is a metal bracket inside of the led Chips, if the material of the bracket is gold or brass, the heat dissipation is very good, but if it is iron, this is very cheap and bad quality.
If the LED Chips on the PCB fail, you need a professional person to change the LED Chips, you also can change the whole PCB, that is easier.
4, Except for the LED flood light itself problem, the fluctuations caused by the overload circuit is the other reason to make the LED flood light flashing. Usually, there is a limited capacity of the circuit cause of the diameter of the wires. So, When you turn on a high power appliance, such as the washing machine, the air conditioner, the momentary overload of the electric current make the LED flood light flash.
