LED diffuse reflector light bar refers to the assembly of LED chips on a hard PCB board to produce a new type of backlight product with higher brightness and a larger light-emitting angle.

The selection of LED diffuse light strips should be judged from the following aspects:

1. The quality of lamp beads is fundamental

At present, most LED diffuse reflection 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, there are many types of power from 0.1w to 1w. The brightness varies greatly from 20lm to 110lm. When choosing LED diffuse 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 bead

At present, most of the lenses of LED diffuse reflection light strips are made of high-efficiency lenses made of PMMA. The advantages of this material: high light transmittance (about 93% when the thickness is 3mm); Disadvantages: temperature resistance 70%, thermal deformation temperature 90 degrees. The light effect of the lens directly affects the brightness of the lamp bead. In addition, the light-emitting angle of the lens also has a certain impact on the light effect of the LED diffuse reflector, 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 samples for testing to see the actual effect.

3. The quality of the heat dissipation of the circuit board affects the life of the LED diffuse light strip

Because most of the LED diffuse reflection light strips use high-power lamp beads of about 1W, they have relatively high requirements for heat dissipation, and the lens also has requirements for temperature, so it is recommended to choose a circuit board with high thermal conductivity when choosing, which can not only To meet the heat dissipation requirements, it can also ensure the service life of the light bar.

These are some of the factors that should be considered before purchasing LED diffuse light strips.
