The invention effectively solves the above problems. The LED light source used in the LED jewelry lamp itself is a cold light source, and the light emitted does not have any heat. At the same time, when the LED jewelry lamp is working, the heat generated in the electro-optical conversion process is much less than that of the traditional metal halide lamp. The light emission of the LED light source used in LED jewelry lamp is determined by the wavelength, so the light does not contain ultraviolet rays and infrared rays, so the jewelry itself will not be damaged. LED jewelry lamp has high color rendering and pure light color, which illuminates the color of jewelry.
