Glare suppression design for LED cabinet lights requires a comprehensive approach encompassing multiple dimensions, including light source concealment, optical structure optimization, material selection, and installation layout, to achieve a comfortable lighting effect where the light source is "seen but not actually seen." Concealing the light source is a core anti-glare strategy. Deeply hiding the light source expands the light-shielding angle, reducing the probability of direct light hitting the eyes. For example, embedding LED chips inside the lamp body utilizes the lamp body structure to create physical shielding, allowing the light to be reflected or refracted softly. Some high-end products employ a 90-degree vertical light-emitting design, preventing the light source from being exposed even when the cabinet height exceeds the human eye's range, completely eliminating the risk of glare.
Optimizing the optical structure is another crucial path. By incorporating a stepped anti-glare structure or honeycomb grid inside the lamp body, light can undergo multi-level refraction and diffuse reflection. The stepped design gradually attenuates the light intensity, preventing direct, strong light; the honeycomb grid cuts the light into fine beams, forming a uniform and soft light spot after multiple reflections. Furthermore, the application of optical lenses can focus light and prevent scattering. Combined with frosted or diffused coatings, this further softens the light and reduces glare. For example, LED beads with diffused coatings can "diffuse" focused light, reducing direct glare.
Material selection is equally crucial for glare suppression. Soft-light materials such as milky glass and acrylic can create a soft transition as light passes through through diffuse reflection, avoiding harsh, direct light. These materials act like a "veil" over the light, significantly reducing glare. Simultaneously, the lamp housing material must have low reflectivity to avoid secondary glare caused by a smooth surface. For example, matte materials reduce light reflection on the surface, reducing reflected glare at the source.
The rationality of the installation layout directly affects glare control. The lamp position should avoid direct line of sight in areas of human activity. For example, when installed above a kitchen countertop, ensure that the light shines perpendicularly onto the countertop, rather than directly into the user's line of sight. For recessed lighting, the position and depth of the openings must be precisely controlled to avoid exposed light sources due to installation errors. In addition, indirect lighting methods, such as concealing LED strips under cabinets or on side panels, utilize reflected light to illuminate the space, providing ample illumination while completely eliminating glare.
The auxiliary design of light shields and grilles can further enhance the anti-glare effect. Light shields, by adjusting the shading angle, block the direct light from the LED beads; a shading angle exceeding 30 degrees is generally recommended. Grille structures, through physical blocking, confine light within a specific angle range, preventing light from diffusing into the eyes. For example, spotlights with grilles can significantly reduce light spillage, ensuring a balance between lighting directionality and anti-glare performance.
The combination of ambient light and auxiliary lighting can reduce perceived glare. By adding auxiliary light sources such as wall lamps and LED strips, the overall ambient brightness can be increased, reducing the contrast between the LED cabinet light and the surrounding environment, thereby reducing glare stimulation. For example, installing low-brightness LED strips in kitchen corners provides basic lighting while avoiding the visual discomfort caused by a single strong light source.
Reducing reflective surfaces is an implicit requirement for glare suppression. Cabinet materials should ideally be matte or low-gloss, avoiding highly reflective materials such as mirrors and glossy tiles. Reducing reflective surfaces lowers light reflection intensity, thus mitigating glare sources from an environmental perspective. For example, matte cabinet doors effectively absorb light, preventing secondary glare caused by reflection, creating a synergistic effect with the anti-glare design of LED cabinet lights.
