How to judge compatible led tube is qualified?

Date:25-08-2017

   Compatible with LED lamp to replace the traditional fluorescent tube, the installation process will need to remove the original electronic ballast or it will be bypassed. The rewiring involves a number of electrical safety operations requiring the operator to have a electrical certificate, which greatly increases the replacement cost of the compatible LED lamp.
   
In order to switch to compatible LED tubes to bypass the ballast, rewiring. So there is a so-called compatible electronic ballasts compatible LED lamp products can be used to replace the traditional fluorescent lamps. Such products are not installed when the electronic ballast, no need to re-wiring, just remove the old fluorescent tube, plug in a new compatible LED tube can be. The installation process is very simple and the replacement cost is very low. But in view of the reality of the situation there are a large number of different brands, different power, different BF,different design of the electronic ballast has been installed to use, if directly compatible with such LED tube connection, there is an electronic ballast with Lamp matching and compatibility issues. Therefore, compatible with LED lamp and traditional ballast "compatibility" has become the most important feature of such products.
  
Compatible led tube compatibility is what the concept of it? Product "compatibility", the first is the safety test, followed by performance testing. If the safety test is gone, talk about any performance is in vain. The safety test includes at least the Pin-Safety test and the Mis-Use test. Pin-Safety test is to simulate the end of the lamp into the lamp socket, the body exposed to the other end of the lamp when the risk of electric shock. UL certification, for Type A and Type B lamp leakage test requirements are different. For Type B lamps, M.I.U must be less than 5.0. Mis-Use test is the analog lamp is mistakenly connected to a variety of lamp holder, including single-ended, double-ended, AC, DC, etc., whether it will lead to electric shock, short circuit, trip or even fire Danger. This is actually a very important safety test, but is often overlooked. The so-called "two-in-one", "three-in-one" products on the market, many of the security tests are too much, the security risks are extremely high.
   
How to test? (BF / 0.78 / 0.88 / 1.18, etc.), different input voltage, and even a point of a lamp, different from the power, , Two lights, three lights, four lights work, check the LED drive current is constant. If the drive current range is large, it means that the LED lamp beads operating temperature, light failure, output lumens and light effects and other key parameters in the actual application environment will change greatly, then compatible with LED lamp nominal performance parameters are often unable to achieve , Light failure is also difficult to control.
