Polycrystalline series lamp beads use advanced polycrystalline technology and have stable and reliable performance. From the optical characteristics, it has excellent luminous flux and uniform light distribution, which can bring comfortable and sufficient brightness to the lighting environment. Excellent performance in energy consumption, which can effectively reduce energy consumption and achieve energy-saving goals. Polycrystalline series lamp beads are widely used in signal indication, sign lights, LCD backlight, 3C products (computers, communications and consumer electronics) wearable and portable devices, and medical care applications.
