Instructions for use of the LED module
In the process of using LED light emitting module, the problem of voltage drop must be paid attention to. Do not just do a loop, from the first series tail. This will not only lead to inconsistent brightness between the head and the tail due to different voltage, but also cause the problem that the single circuit current is too large and the circuit board will be burned out. The correct approach is to shunt as many loops as possible to ensure a reasonable distribution of voltage and current.
Have enough brightness. Module spacing, visual brightness is required between 3 and 6CM, and the word thickness is selectable between 5 and 15CM. There are two types of LED light sources for light emitting characters: piranha and small straw hats. The piranha luminous module is suitable for the luminous words between the 8-15cm of the wall height.
If the module is more than 25 groups, should be separately connected by high quality copper wire is greater than 1.5 mm in parallel connected to the light box body, power line length should be as short as possible, such as more than 3 meters should be appropriate to increase the line diameter, without connection to avoid module terminal short circuit must be cut and paste we must firmly, if necessary by self tapping screws fixed waterproof series for outdoor use, must be waterproof groove word;
In order to avoid the switch power supply working at full load for a long time, the switching power supply and the LED load power are best 1:0.8. According to this configuration, the service life of the product will be more safe and lasting.
Light source with luminous words at this stage mainly in the general settings input voltage source module for DC12V LED three, five lights, six lights lamp is common through the switching power supply output constant voltage DC12V power supply, so be careful if you do not install switching power supply installation light, avoid light emitting word or LED light source module into 220V AC power directly, otherwise it will be because the voltage is too high and burn LED light source.
