Jewelry display cabinets are mostly designed in the form of specialty stores, shops in stores and island cabinets, and the lights made by jewelry counters are also the brightest areas in shopping malls. The lighting design of jewelry counters first comes from the top light source. Specialty stores or in-store shops usually use top metal halide lamps and spotlights as the main light sources, while island cabinets use strip lighting to improve the overall lighting of jewelry counters. The interior of the counter is mostly illuminated by fluorescent lamps to improve the overall brightness. In addition, cold spotlights and LED lamps are installed at the left and right corners of the front of the counter as supplementary light sources to improve the three-dimensional sense of jewelry. Especially the diamond counter, illuminated by corner spotlights or LED lights, reflects the unique angular texture of diamonds, thus stimulating customers' desire to buy. Jewelry display cabinets usually display small and exquisite items, which can be illuminated by spotlights or optical fibers. Pay attention to the collocation of light and color. For example, gold ornaments can be illuminated by cold cups, and silver products or gem products can be illuminated by daylight cups. Due to the generation of heat, it is necessary to consider the treatment of heat dissipation factors of display cabinets. If the project cost permits, optical fiber lighting is also a good choice, with the advantage that it will not bring too much heat to the display cabinet. Lighting design pays attention to the principle that you can't see the light when you see it, and highlights the items displayed.
