Factory Direct LED waterproof module 5730/2835

 Voltage LED in 2-4v range, power also has a wide range, specific choice of which depends on the LED module as the technical requirements of a product for the. For example, the output of the LED module needs 10lm light appearance with two LED is better, you can choose 5lm one of the LED. Binding color (LED voltage and color-related), other factors such as temperature, quality, etc., you can find a suitable product LED. First, at this stage the main source luminous characters spend in a conventional set of input voltage is DC12V three LED lights, five lights, six light source module is relatively common, through DC12V constant voltage output of the switching power supply for power, so If you do not pay attention to install luminous characters switching power supply, should not be luminous characters or LED light source module is energized AC 220V power directly into the market, because otherwise it will be LED light source voltage is too high and burn. Second, in order to avoid long-term work at full capacity switching power supply, switching power supply with LED load power best to 1: 0.8, according to the life of the product so configured will be more secure and lasting. Third, if the module more than 25 groups, should be separately connected in parallel and then by the more than 1.5 mm2 copper wire with high luminous characters outside the box is connected to the power cord length should be as short as possible, as more than three meters must appropriate to increase the diameter, not the end of the module wiring must be cut in order to avoid short-circuiting paste must be strong, if necessary, when using self-tapping screws are not waterproof outdoor use, channel letters must be prepared waterproofing; Fourth, there must sufficient brightness. Module spacing required visual brightness between 3 6CM, a thickness of between 5 to optional word 15CM. Suitable for luminous characters LED light source, there are two: piranhas and small straw hat. Piranha LED module suitable for gable height 8-15cm between the luminous words. Fifth, the use of LED light module in the process, must pay attention to voltage drop problems. Do not only do a loop, from the end of the first series. This will not only due to the voltage difference between the brightness caused by inconsistent end to end, will produce single overcurrent burned circuit board problem. The correct approach is more parallel loop as much as possible, in order to ensure a reasonable distribution of voltage and current. Sixth, the internal cavity for the use of the word anti-corrosion materials, preferably with a white primer to increase its reflection coefficient.
