What to pay attention to when designing UL certified AC light source module

UL-certified AC LED Light module source module can carry out greater optical design, heat dissipation design, shape, size design and interface standardization design according to any form of application. Through the above design, the standardized combination of lamps and lanterns in different application places can be realized, and it is convenient to use. And according to the function of the replaceable module according to the life, the user's cost can be reduced to a greater extent.
The color rendering index (the ability of the LED Light module source to reproduce the true color) is one of the three important indicators to measure the quality of the white light source, and it is also an important standard for measuring the health of the UL-certified AC light source module. It is an indicator in the field of lighting. The status of China is particularly obvious.
Instructions for use:
1. At this stage, the light source with luminous characters is mainly based on the conventional setting of the LED three-lamp, five-lamp, and six-lamp UL certification AC light source module with the input voltage of DC12V. The DC12V is the power supply, so be careful if you don’t install the switching power supply when installing the luminous characters, do not directly connect the luminous characters or the light source module to the mains AC 220V, otherwise the LED light source will be burned out due to the high voltage.
2. In order to avoid long-term full-load operation of the switching power supply, the power of the switching power supply and the LED load is preferably 1:0.8. According to this configuration, the service life of the product will be more secure and lasting.
3. If there are more than 25 groups of UL certified AC light source modules, they should be connected separately, and then connected to the outside of the luminous box by high-quality copper core wires larger than 1.5 square millimeters in parallel. The length of the power cord should be as long as possible Short, if it exceeds 3 meters, the wire diameter must be appropriately increased. The unused wires at the end of the module must be cut and pasted to avoid short circuits. If necessary, use self-tapping screws to fix the non-waterproof series. When outdoor use, the groove type must be waterproof; < br />
4. There must be sufficient brightness. The visible brightness of the light source module spacing needs to be between 3 and 6 cm, and the thickness of the characters can be between 5 and 15 cm.
5. In the process of using UL certified AC light source module, we must pay attention to the problem of voltage drop. Don't just make a loop, connect from the beginning to the end. Doing so will not only cause inconsistent brightness between the end and the end due to the difference in voltage, but also cause the problem of burning the circuit board due to excessive single current. The correct way is to connect as many circuits in parallel as possible to ensure a reasonable distribution of voltage and current.
6. If anti-corrosion materials are used inside the cavity, use white primer as much as possible to increase its reflection coefficient.
