Professional Custom Lamp Holder Accessories Manufacturer

Some manufacturers in order to reduce product cost, using " RC Buck " approach to power LED products , this will directly affect the life of LED products. Using a dedicated switching power supply for LED products will not affect the life of the product , but the product cost is relatively high .

Anti-static measures should be done

LED products in the processing and production process to the use of certain anti-static measures, such as the table to the ground , workers wear anti -static clothing, anti-static belt loop and with anti -static gloves , anti-static conditions can install the fan, while but also to ensure the workshop humidity around 65 %, so the air is too dry to produce static electricity , especially the green LED is more easily damaged by static electricity .

Many people do not have static problems are due to ESD ( electrostatic discharge ) caused by consciousness , this is because most ESD damage occurred outside the person's feelings , because the perception of the human body electrostatic discharge voltage of about 3KV, and many of the electronic components in a few hundred volts will damage even when tens of volts . Usually after being damaged electronics ESD no clear boundaries , the components are mounted on the PCB after re-testing , the results of a lot of problems , the analysis is quite difficult.

LED temperature

Note that the resistance LED temperature will become smaller . When the ambient temperature rises , LED light resistance will be reduced, if the use of a regulated power supply will cause the LED current increases, when more than its rated operating current , it will affect the life of LED products will enable serious LED light source , " burn " , so the best selection of constant current source power supply to ensure that LED current is not affected by the outside temperature .

Sealed LED products

No matter what LED products , when applied to outdoor , are faced with waterproof, moisture-proof sealing problems , if not handled properly it will directly affect the life of LED products. There are a small number of relatively high demand for product quality manufacturer of traditional epoxy resin " pour " method to seal the LED products, this method of operating is too much trouble for the larger volume of LED products will result in increased weight .

LED current can not exceed the LED current IF

LED life work will soon fall overcurrent , if exceeded, will immediately burn the LED .

It should be noted LED CORNER

LED in the corner or knuckle Please do not gel too close , you should keep a distance of more than 2mm and colloids, which otherwise would stand with LED colloidal gold wire separation, the number one place in the folded corners should not exceed three times, bent corners 90 degrees, and then return to the original position once .

Soldering Temperature

Soldering temperature is around 260 degrees Celsius, time controlled within 5S, welding points more than 2.5mm from the bottom of the colloid , electric iron must be grounded , absolutely not permitted to live welding LED.
