How to ensure that the light from LED cabinet lights is evenly distributed to avoid shadows or light spots?

In the design of cabinet lighting, uniform light distribution is the key to improving visual comfort and practicality. If the light distribution is uneven, it is easy to produce obvious shadows or light spots, affecting the user experience. To ensure that LED cabinet lights can provide uniform and soft lighting effects, it is necessary to optimize the arrangement of lamp beads, diffusion materials, installation positions, irradiation angles and dimming control, so that the light can better cover the entire cabinet area.
If the distance between lamp beads is too large, it is easy to cause discontinuous light distribution and form obvious light and dark areas. Therefore, when designing, the distance between lamp beads should be minimized to make the light source denser to reduce the uneven lighting. The use of multi-row lamp bead design can effectively expand the irradiation range, avoid the obvious light and dark transition of single-row lamp beads during the irradiation process, and make the light cover the entire cabinet space more evenly.
The choice of diffusion material has an important influence on the uniformity of light. Lampshade materials with high light transmittance but good diffusion effect can make the light softer and reduce the generation of light spots. For example, the use of frosted or milky white lampshades can effectively diffuse the light and make the lighting range more uniform. If a transparent lampshade is used, the light may directly shine on the surface of the cabinet, forming a local over-bright or over-dark area. Therefore, when designing lamps, the rational selection of diffusion materials can effectively improve the lighting quality and reduce shadows and light spots.
The rationality of the installation position determines the coverage of the light. If the installation position of the LED cabinet light is too concentrated or deviates from the use area, it is easy to cause uneven lighting. Therefore, the installation position of the lamp should be reasonably planned according to the layout of the cabinet, so that the light source is as close to the working area as possible, and avoid obstructions that affect the light propagation. For example, when installing lamps at the bottom of the wall cabinet, it should be ensured that the light can evenly cover the entire operating table, rather than just concentrating on a small area.
If the light is directly irradiated, it may form a strong reflection or light spot on the surface of the cabinet. Therefore, when installing LED cabinet lights, a certain angle tilt design can be adopted to make the light diffuse evenly to the entire cabinet area after refraction. At the same time, using lamps with adjustable angles can also be fine-tuned according to different lighting needs to make the light coverage more reasonable and avoid excessive concentration or dispersion.
To further reduce shadows, you can use a combination of multiple light sources to project light from different directions to eliminate dark areas that may be caused by a single light source. For example, install multiple small LED light strips in different parts of the cabinet so that light can be irradiated from multiple angles, thereby reducing the appearance of shadows. In addition, using embedded or hidden installation methods can also avoid the lamp itself blocking part of the light, ensuring more uniform lighting throughout the cabinet area.
