The light uniformity design of high-end cabinet light is first reflected in the precise planning of light source layout. The internal structure of the cabinet is complex, and there are obstructions such as shelves and partitions, which are easy to form shadow areas. Designers will reasonably arrange lamps in key positions such as under the shelves and inside the cabinet according to the layer height and depth of the cabinet and the placement habits of the internal items to ensure that each area can be covered by light. For example, in a deeper drawer, strip light sources will be installed on both sides of the drawer to allow light to shine from both sides to the middle, avoiding dark areas in the deep drawer due to the distance from the light source. Through the multi-directional distribution of light sources, the lighting dead corners are eliminated from the space.
The luminous characteristics of the light source itself are also the key to achieving uniform lighting. High-end cabinet light mostly uses SMD LED light sources, which have a larger luminous angle and can spread the light to a wider range instead of concentrating in a certain direction. Compared with traditional point light sources, SMD LEDs emit softer light and will not produce strong light and dark contrast due to excessive light concentration, so that every corner inside the cabinet can get relatively balanced light. At the same time, the color rendering index of the light source is high, which can truly restore the color of the object. Even in areas with weak light, it will not appear dim due to poor color rendering, which indirectly reduces the visual dead angle.
The design of the lampshade and translucent materials of the lamp plays an auxiliary role in the uniform diffusion of light. The lampshade adopts a frosted or micro-prism structure, which can refract and scatter the light emitted by the light source multiple times, making the originally concentrated light beam more dispersed and evenly projected into the interior of the cabinet. The uniformity of the translucent material is also very important to avoid the difference in light and dark when the light passes through due to uneven thickness of the material, and ensure that the light can form a complete light surface after being emitted from the lamp, covering every detail of the cabinet, especially the edges of the shelves, the corners of the cabinet body and other places that are easily overlooked.
For special structures inside the cabinet, such as corner cabinets and special-shaped cabinets, the light uniformity design will adopt a more targeted solution. Because the two cabinets are vertically connected at the corner, cross shadows are easily formed. The high-end cabinet light will install a rotatable universal light source on the inside of the corner. By adjusting the angle of the light source, the light can bypass the corner and illuminate the interior space in both directions. For the curved area of the special-shaped cabinet, a flexible light strip will be used to fit the curved surface, so that the light can naturally extend along the curvature of the cabinet, avoiding the dead corners that cannot be covered by the light due to the irregular shape of the cabinet.
The reflection and superposition principles of light are also cleverly used in uniform lighting. The inner wall and the surface of the shelf inside the cabinet usually use light-colored and smooth materials. These materials can reflect part of the light and enhance the diffusion effect of light. When the light emitted by the light source hits these surfaces, it will be reflected to other areas and superimposed with the directly illuminated light, so that the brightness of the originally weakly illuminated area is improved. For example, for the light source installed on the inside of the cabinet, part of the light directly illuminates the object, and the other part is reflected by the inner wall to illuminate the deep part of the cabinet. Through this reflection supplement, the dead corner caused by the inability of the light to reach directly is reduced.
The dimming function of the lamp provides a guarantee for uniform lighting in different scenes. When taking and putting items in daily life, the light needs to cover the whole area; when displaying the tableware and accessories in the cabinet, it is necessary to highlight the key points without losing the overall uniformity. The high-end cabinet light uses delicate dimming technology to adjust the brightness while maintaining the uniform distribution of light, and will not cause some areas to darken and form dead corners due to reduced brightness. For example, when the brightness is adjusted to a lower level, the luminous range of the light source remains stable, ensuring that the brightness ratio of each area inside the cabinet remains unchanged and avoiding local over-darkness.
The degree of refinement of the installation process also affects the uniformity of light. The fit between the lamp and the cabinet should be high to avoid light leaking out of the gap or being blocked due to uneven installation, forming unnecessary shadows. The lamp installed under the shelf will maintain a precise distance from the edge of the shelf to ensure that the light can illuminate the items below without creating heavy shadows on the edge of the shelf due to too close distance. At the same time, the wiring of the lamps is concealed, and the light will not be blocked by protruding wires, ensuring that the light can be smoothly projected to every corner, eliminating possible lighting blind spots from the installation details.
