With the application of LED diffuse reflection light strips (rolling shutter) in the field of advertising light box backlighting more and more popular, coupled with the smaller and smaller size of a single LED package, the power is getting bigger and bigger, the brightness is getting higher and higher , LED diffuse reflector light strip (roller shutter type) came into being. Its ultra-high brightness coupled with appropriate lenses allows only 4-5 light strips to be used for a square meter of light box backlight, which greatly reduces the cost of light box LED diffuse reflection light strips (rolling shutter type). So what are the precautions for choosing LED diffuse light strips (roller shutter type)? The following will start from several aspects and teach you how to choose a good light box LED diffuse light strip (rolling shutter).

The selection of LED diffuse reflection light strips (rolling shutter type) should be judged from the following aspects:

1. The quality of the lamp beads is fundamental.  At present, most LED diffuse reflector light strips (rolling shutter type) use 2835 or 3030 packaged lamp beads, and the same 2835 or 3030 lamp beads have different power and brightness. Take 2835 as an example, there are many models of power from 0.1w to 1w, and the brightness varies greatly from 20lm to 110lm. When choosing a light box LED diffuse reflection light bar (rolling shutter type), you must know these parameters. It is good to take a sample and test it to see if the effect can meet your needs.

2. The light efficiency of the lens affects the brightness of the lamp bead  At present, most lenses are made of high light efficiency lenses made of PMMA. The advantages of this material: high light transmittance (about 93% when the thickness is 3mm); Disadvantages : Temperature resistance 70%, heat distortion temperature 90 degrees. The light effect of the lens directly affects the brightness of the lamp bead, and the light-emitting angle of the lens also has a certain influence on the light effect of the light bar, especially when the thickness of the light box is relatively thin (such as less than 6cm), it is recommended to choose professional manufacturers or Take the sample test and see the actual effect.

3. The heat dissipation of the circuit board affects the life of the light bar  because the LED diffuse reflector light bar (rolling shutter type) mostly uses high-power lamp beads with a power of about 1w, which itself has relatively high requirements for heat dissipation, plus The lens also has requirements on temperature, so it is recommended to choose a circuit board with high thermal conductivity when choosing, which can not only meet the heat dissipation requirements, but also ensure the service life of the light bar.

Finally, it is recommended that you choose products from professional manufacturers when purchasing light box LED diffuse reflector light strips (roller shutter type).
