With the application of LED diffuse reflection roller shutter light strips in the field of advertising light box backlighting, it is more and more favored by customers. In addition, the volume of a single LED package is getting smaller and smaller, the power is getting bigger and bigger, and the brightness is getting higher and higher. The led diffuse reflection roller shutter light strip came into being. Its ultra-high brightness coupled with appropriate lenses enables only 4-5 light strips to be used for a square meter of light box backlight, which greatly reduces the cost of light box backlight LED roller shutter light strips. So what are the precautions for choosing LED diffuse reflection roller shutter light strips? Xiaobian will teach you how to choose a good LED diffuse reflection roller shutter light bar from several aspects.

The selection of led diffuse reflection roller shutter light bar should be judged from the following aspects:

1. The quality of lamp beads is fundamental

At present, most LED diffuse reflection roller shutter light strips use 2835 or 3030 packaged lamp beads. The same 2835 or 3030 lamp beads have different power and brightness. Take 2835 as an example, its power varies from 0.1w to 1w. There are many There is a huge difference in brightness between 20lm and 110lm. When choosing LED diffuse reflection roller shutter light strips, you must know these parameters. It is best to take samples to actually test to see if the effect can meet your needs.

2. The light effect of the lens affects the brightness of the lamp beads

At present, most of the lenses are high-efficiency lenses made of PMMA. The advantages of this material are: high light transmittance (about 93% when the thickness is 3mm); Disadvantages: temperature resistance of 70%, thermal deformation temperature of 90 degrees. The light effect of the LED diffuse reflection roller shutter light bar lens directly affects the brightness of the lamp bead. In addition, 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 a professional manufacturer or take a sample for testing to see the actual effect.

3. The heat dissipation of the circuit board affects the life of the light bar

Because most of the LED diffuse reflection roller shutter light bars use high-power lamp beads with a power of about 1W, they have relatively high requirements for heat dissipation, and the LED diffuse reflection roller shutter light bar lens also has requirements for temperature, so it is recommended when choosing. Choose a circuit board with high thermal conductivity, 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 LED diffuse reflection roller shutter light bars. For any questions about LED diffuse reflection roller shutter light bars, you can consult our staff at any time.
