Jewelry lamp is a kind of lighting decoration inspired by jewelry, which is both artistic and functional. It is mainly used in jewelry display cabinets and counters 1. The following is a summary of key knowledge points: I. Core features Materials and technology  Using high-quality materials such as crystal, glass and metal, combined with precision technology, it presents exquisite appearance and unique shape . Lighting design  Selection of light source: use more light sources with high color rendering and close to natural light (such as CREE LED) to ensure color reproduction and avoid the damage of ultraviolet rays to jewelry 2. Color temperature and color rendering: yellow light, neutral white or sunlight white are commonly used, and the color rendering index is ≥90, which highlights the details and luster of jewelry. Color rendering and anti-glare: through the design of special optical lens and uniform light source, glare can be avoided, and the surface color of jewelry can be protected from high temperature or ultraviolet rays. Function and effect  Enhance the texture of jewelry: enhance the luster of diamond fire and jade through soft light, and make jewelry more brilliant . Artistic quality and atmosphere: it combines creative design to create a romantic and warm exhibition environment, which has both decorative and practical value. Second, the difference between ordinary lamps and lanterns 1 Material and design: Jewelry lamps pay more attention to the exquisiteness of materials and process details, and the design emphasizes uniqueness and artistry; Ordinary lamps focus on practicality and cost performance 1. Lighting characteristics: Jewelry lamps have higher color rendering, lumen efficiency, low heat radiation, ultraviolet protection and other characteristics, but ordinary lamps may lack these optimizations. Third, suggestions for purchase and use Parameter selection: give priority to color rendering index (≥90), color temperature (4000K-5000K) and lumen efficiency (≥100lm/W) to avoid high heat radiation and stroboscopic. Matching principle: adjust the lighting according to the type of jewelry, such as high-brightness light source for gold and diamonds, and soft light for jade and crystal; Avoid a single light source and use multi-level lighting to enhance the layering.
