With the continuous expansion of the application field of LED injection molding modules, the output of LED injection molding modules has also doubled several times. However, if a lens that is suitable for LED injection molding modules is not selected in manufacturing, it will cause many problems, such as light spots on the canvas. , dark areas, etc. So how to choose the lens with the right angle for the LED injection molding module? According to the use of the product, the corresponding lens angles are also different.
Generally speaking, the lens angle refers to the size of the luminous range after the LED injection molding module is lit, that is, the beam angle. The response on the illuminated wall is the spot size and light intensity, the same light source. If used in reflectors with different angles, the larger the beam, the smaller the central light intensity and the larger the spot. We simply analyze the beam at a 6° angle, and we can clearly see that the light at the center of the beam at a 6° angle is significantly brighter than the surrounding area. The middle part of the light is called the center light intensity, and the entire light irradiation surface is called the spot. As the beam angle of the LED injection molding module increases, the intensity of the middle light decreases. When the angle reaches 120 degrees, the brightness of the light in the middle part is almost the same as that of the surrounding area, which is no different from the light effect of ordinary lamp beads. Therefore, we can draw the conclusion: the smaller the beam angle, the greater the light intensity in the center, the smaller the spot, and the better the light effect.
In the design process of the LED injection molding module, the source of the beam angle is the lens angle. The beam angle can be locked as long as a lens with a corresponding angle is added to the LED injection molding module. At present, the common beam angles on the market are 8°, 15°, 25°, 45°, 60°, 90°, and 120°. According to the angle, they can be divided into: narrow-angle beam: <20°; medium beam 20°~40 °; wide beam > 40°. Different lens angles lead to different apertures and illumination areas. The parameters of apertures and illumination areas at different distances for several common angles of LED injection modules are listed below.
30 degree angle:
1 meter aperture diameter 0.56M irradiation area 0.246 square meters
2 meters aperture diameter 1.12M irradiation area 0.985 square meters

2 meters aperture diameter 1.656M irradiation area 2.154 square meters
3 meters aperture diameter 2.484M illumination area 4.864 square meters
60 degree angle:
1 meter aperture diameter 1.15M irradiation area 1.046 square meters
2 meters aperture diameter 2.3M irradiation area 4.189 square meters
3 meters aperture diameter 3.46M illumination area 9.424 square meters
120 degree angle:
1 meter aperture diameter 3.464M illumination area 9.424 square meters
2 meters aperture diameter 6.928M irradiation area 37.697 square meters
3 meters aperture diameter 10.392M irradiation area 84.818 square meters
