The Problems That Often Occur in Infrared LED Lamp Beads Are Solved.

1) Check whether the power supply of the power supply has normal operations, and whether the demonstration lights are on. If it is not turned on, please check if the power supply is connected; , Is there any opposite, if there are above questions, please be able to connect accurately. LED lamp beads named 3V, in fact, different colors also have different requests for current. ** The request current is the smallest, which is red, green, white and blue. 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. At the time of using buttons, because the voltage of the buttons is 3V, because the discharge current of the buttons is small, the 3V LED lamp bead will not be burned. Therefore, when using LED lamp beads, you should choose a suitable power supply, pay attention to the voltage, and the current. When the power supply is selected, if the additional requests of the LED lamp bead are not fits, the demand will improve the circuit. Under the condition of unreasonable installation resistance, if it is convenient to choose during procurement, it advocates a 3V buckle battery. When choosing, use the battery to conveniently check what the LED is sent out. 1) Two filaments up and down. Our industry is called golden line, pure gold, and is used as conductive electrical, two positive poles, two negative poles. The protection effect 2) The short filament has now clearly told you that your light has been burned by a large current, which is equivalent to disconnecting 3) Drive current with a high power of 1W is at 350mA, and the operating voltage is 3.2-3.2- Between 3.6V, please pay attention when applying, too large currents will definitely burn the lights 4) Usually three 1W aluminum -based plates are driven by 12V. Is there a missing source that is less than a 12V driving power? LED outer sealing rubber yellow factor eight becomes formed by the non -matching of epoxy tree esters and curing agents Long -term. Solution: Purchase into an outer seal and curing agent, such as the type 800 or 2339 glue of Shanghai Fine Chemical Everbichels, which will not show the following conditions. Also pay attention to production and control, strictly follow the operation of operations , This situation is extremely well controlled. The equipment is not grounded, and the personnel do not wear a static bracelet (must have a rope). Electrostatic protection formed is inappropriate. Then, during the package, the welding line PAD welding is ultimately questioned. Both were not. LED lamp beads were a second-level tube. It required a positive turnover voltage to operate, usually 2-3.5V. That is to say, LED lamp beads just transform electrical energy into light energy. There are four factors for the attenuation of small power LEDs: 1: Poor heat conduction of iron barriers. Two: epoxy resin yellowization. Three: chips and brackets are not tightly touched. Four: The chip is attenuation. If it is white light, there is also a question of fluorescent powder attenuation.
