About the Daily Common Problems of Deep Ultraviolet LED Lamp Beads

About the daily common problems of deep -ultraviolet LED lamp beads 1. It is caused by abnormal power supply: 01. Check whether the power supply power supply has normal operations, and whether the indicator light is on. If it does not light up, please check if the power supply is connected; 02. Check whether the power cord of the lamp beads is the same as the positive and negative power supply of the power supply supply. If there is any reverse, if there is the above problems, please connect correctly. 2. LED lamp beads for voltage requirements: LED lamp beads named 3V, in fact, different colors also have different requirements for currents. The yellow requirement current is the smallest. If the current is too large, the core will be burnt. Use a 2.4V rechargeable battery, ** is easy to burn, because even if the voltage is not large, the current is too large, it will still be burnt at will. 3. In the case of non -power detection LED: In the case of not power, if it is convenient for choosing when buying, it is recommended to prepare a 3V buttage battery, and use the battery to easily check what light the LED sends out. 4. Reasons for the burning of high -power LED lamp beads: 01. Two filaments of upper and lower filaments. Our industry is called golden line, pure gold. Root line, welded on the Qina pipe, played a maintenance role. 02. Turn on the filament will be clearly telling you that your light has been burned by a large current, which is equivalent to disconnection. 03. The driver current of 1W is about 350mA, and the operating voltage between 3.2-3.6V is between 3.2-3.6V. Please pay attention when used. 04. Generally, the aluminum -based plates of three 1W lights are driven by about 12V, and rarely uses 220V directly. Do you see if you have a constant current source or a 12V driver power? 5. The reason for the yellowing of LED lamp beads: The reason for the yellowing of the outer sealing hair is mostly formed by the non -matching of the epoxy tree esters and the curing agent, but it cannot be ruled out that the baking time of the outer seal is too long and the baking time is too long. Solution: Buy a set of outer sealing and curing agents, such as the model 800 or 2339 glue of Shanghai fine chemical models, and the following conditions will be paid to the production control, strictly follow -up operations to prevent the baking time from being too long or inadequate, etc. , This situation is very good. 6. The reasons for leakage of LED lamp beads: The machine equipment is not grounded, and the personnel do not wear the electrostatic bracelet (must have a rope). Electrostatic protection formed is inappropriate. Then, during the package, the welding line is welded, and the last is the problem of hidden dangers of the chip itself. 7. LED lamp beads should be the problem of tolerance and emotional load: In fact, neither of the two, LED lamp beads are a second-level tube. It requires a positive drive voltage to operate. Generally In addition, the current of the current can control the brightness of the LED lamp bead. That is to say, LED lamp beads just converted electrical energy to light energy. 8. Reasons for the decay of LED lamp beads: There are four reasons for the attenuation of small power LED: 1: Iron barriers are poor. Two: epoxy resin yellowization. Three: chip and brackets are not tight enough. Four: The chip is attenuation. If it is white light, there is a problem of attenuation of fluorescent powder.
