What is the difference between LED side light and direct light?

.
2   The distance between the lamp beads and the PC diffusion plate must be large because of the large distance between the lamp beads of the direct light-emitting panel lamp, so that the dark area will not be formed when the lamp beads are lit.
the light emitted by the lamp beads of the side light-emitting panel lamp will be reflected by the reflective film of the light guide plate.
after passing the light guide plate, the luminous flux will be lost to a certain extent.
when the lamp beads of the side light-emitting panel lamp are lit, the luminous flux will be reduced  . the width of side light-emitting panel lamp is generally 8mm-12mm, which is much thicker than that of side light-emitting panel lamp.
.
4. However, the light flux of direct light-emitting panel lamp is higher than that of side light-emitting panel lamp under the same condition.

extended data.
the size code of LED side light-emitting lamp bead is 335.
the number of lamp beads per meter is 30, 60, or 120, The colors are: red, green, blue, white, warm white, pink and purple.
.
the biggest difference between the LED side light strip and other LED light strips is the light-emitting mode.
the light is emitted from the side with the largest area of the lamp bead, which is horizontal with the carrier PCB plane, and the light-emitting surface of other light strips such as 3528 and 5050 is facing up, Source: Baidu Encyclopedia - Characteristics of LED side light bar.
Shenzhen Yueliang lighting reminds you that each of the two lighting modes has its own advantages and disadvantages.
the difference between the structure of positive light panel lamp and side light panel lamp is that there is no light guide plate, and the light guide rate of PMMA is about 93%.
the positive light panel lamp is relatively large due to the large spacing of lamp beadsTherefore, the distance between the lamp bead and the PC diffusion plate must be relatively large, so that the dark area will not be formed when the lamp is lit.
.
the distance between the lamp bead and the PC diffusion plate must be relatively large   The light emitted by the lamp bead of the side light-emitting panel is reflected by the reflective film of the light guide plate, and then radiates out.
after passing through the light guide plate, the luminous flux will be lost to a certain extent.
the light flux of the side light-emitting panel lamp bead will be reduced to a certain extent  . the side light-emitting panel lamp is generally 8mm-12mm, which is much thicker than the side light-emitting panel lamp  .
the advantage of positive light panel lamp is that the luminous flux of the same lamp bead is higher than that of the side light
