Basic Instructions For LED Module

- Apr 27, 2017 -

First, at this stage of light-emitting lamp with the general set of input voltage are mainly DC12V led three lights, five lights, six light source modules are more common, need to pass constant voltage switching power supply output DC12V as power, so pay attention to the installation of light-emitting words if no switching power supply, should not be light-emitting or LED light source module Direct Market AC 220V power, otherwise will be led light source because of excessive voltage burn.

Second, in order to avoid switching power supply long-term full load work, switching power supply and led load power of the best 1:0.8, in accordance with the configuration of product life will be more secure and lasting.

Third, if the module exceeds 25 groups, should be connected separately, and then more than 1.5 square mm high-quality copper core line in parallel connection to the light-emitting box, power cord length should be as short as possible, such as more than 3 meters must be appropriately increased line diameter, modular end of the wiring to avoid short-circuit must be cut-off paste must be firmly, if necessary to use self-tapping screws fixed non-waterproof series of outdoor use, slot-type words must be good waterproof measures;

Fourth, to have enough brightness. Module spacing visual brightness needs between 3 to 6CM, the thickness of the word can be selected between 5 to 15CM. There are two kinds of LED light sources for luminous characters: piranha and small straw hats. The Piranha light-emitting module is suitable for the light-emitting characters of the character wall height between 8-15cm.

Fifth, in the use of LED light-emitting module process, must pay attention to the problem of voltage drop. Do not only do a loop, from the first series tail. This will not only make the difference between the head and end of the voltage caused by the brightness, but also will produce a single-circuit current excessive burn the problem of the circuit board. The correct approach is to try as many parallel circuits as possible to ensure that the distribution of voltage and current is reasonable.

6, the word cavity inside the need to use anti-corrosion materials, preferably with white primer to increase its reflective coefficient.
