The illumination of lighting fixtures in the entire space is generally uneven. Placing the lighting fixture inside the sphere, all the light in the space undergoes multiple diffuse reflections within the sphere, forming a uniform illumination on the sphere. Therefore, the light obtained at any output end of the integrating sphere is a uniform beam. After analyzing the spectral energy of the beam using a spectral analyzer, the energy-saving level of the lighting product can be grasped Characteristics such as lighting quality and even reliability. Analyzing these characteristics can provide a comprehensive evaluation of the quality of lighting products
