It is mainly composed of piezoelectric ceramics, electrostatic screens, metal electrodes, glass silver and other materials. When a high-voltage AC signal acts on piezoelectric ceramics, it changes shape, compresses the gas in the electrostatic screen, generates a high electric field strength, and finally discharges the gas. As a special LED light source, high-voltage lamp beads have the characteristics of high brightness, high efficiency, energy saving and environmental protection. With the continuous development of LED technology, high-voltage lamp beads will be used in more fields, making greater contributions to energy saving, environmental protection and efficient lighting.
[0003] Packaging technology plays a vital role in the performance of LED lamp beads. SMD packaged high-voltage 5054RGBW high-voltage four-color product lamp beads are gradually accepted by the market and have gained a certain market share. The four colors of RGBW are mainly composed of red light chips, blue light chips, green light chips, and white light chips. The high voltage of each color is completed by two cores or multiple chips in series, but its manufacturing cost is high and its production efficiency is low. However, in order to maintain the same thermal conductivity, product parameters, and cost control, R&D technicians use a single high-voltage chip and phosphor to excite the color, which can not only ensure the output and product performance of each high-voltage product color, but also greatly reduce its manufacturing cost and improve production efficiency.
