LED shielded module line (power supply with core band shielding)
One, using light-emitting word light source at present stage mainly with conventional set the input voltage of DC12V LED lamp of three, five lights, six lights light source module is common, need through the constant pressure of switch power supply output DC12V power supply, avoid by all means not to luminous word or the LED light source module directly into electricity ac 220 v electricity, otherwise the LED light source will be burn out because of the high voltage.
2. In order to avoid long-term full-load operation of the switching power supply, the best load power of the switching power supply and LED is 1:0.8. The service life of the product according to such configuration will be safer and more durable.
Three, if more than 25 group, again by more than 1.5 square millimeter of high quality copper wire connected in parallel connection to the outside of the luminous word box body, the power cord length should be as short as possible, such as more than 3 meters must be properly increase the wire diameter, module, not at the end of the wire must be cut and paste to avoid short circuit must be strong, self-tapping screws are used when necessary not waterproof series, outdoor use groove type words need to be waterproof measures;
