What should be paid attention to when installing ETL certified AC light source module

The ETL certified AC light source module is the optical design, heat dissipation design, shape, size design and interface standardization design that can be carried out according to any form of application. Through the above design, the standardized combination of lamps and lanterns in different application places can be realized to achieve convenient use and life-span The function of the replaceable module can reduce user costs to a certain extent.



Installation steps of ETL certified AC light source module:



1. The number of light source modules is estimated at equal intervals, the distribution of LED Light module source modules is simulated on the computer, and the number of light source modules required is initially estimated. The visible brightness of the module spacing needs to be between 3-150px, and the thickness of the characters can be selected between 5-325px.



2. Calculate the power supply and design the number of LED light source modules of the power distribution plan budget × the power of a single LED Light module source module u003d the total power consumption. It is recommended to leave a margin for the power supply selection and use it at 80% of the rated power.



3. Install the LED light source module A: Clean the installation surface B: Stick it on the bottom of the module with double-sided adhesive. C: Arrange evenly and connect the wires. D: Install the word slot panel and measure the effect. E: Final product



Notes for ETL certified AC light source module:



1. The polarity of the light source module: the red wire is connected to the positive stage of the power supply, and the white wire is connected to the negative power supply.



2. The vertical height of the acrylic transparent cover from the light source module should be greater than 5 cm and less than 13 cm to avoid light spots or dark phenomena on the surface of the cover; the transmittance and astigmatism of different acrylic materials Sex has a great influence on height and uniformity, so please pay attention to the selection.



3. Working voltage: Pay attention to the consistency of the voltage of the light source module and the voltage of the switching power supply.



4. Firmly pasting: Ensure that the light source module pasted in the light box is firm and reliable, and fix it with screws if necessary.



5. Wire length: The length of the power cord should be as short as possible (recommended not to exceed 3 meters), greater than or equal to 18AWG#, and the wire diameter should be appropriately increased if it exceeds 3 meters.
