Double-color in-line LED lamp bead

Abstract

The invention discloses a double-color in-line LED lamp bead, which comprises a bowl, a bracket, a wafer, a silver wire and packaging gel, wherein the bowl is fixed on a bracket with a cooling fin; the bracket is provided with the wafer; the wafer comprises a wafer A and a wafer B; the wafer is connected with the bracket through the silver wire; the bowl and the bracket are arranged in the packaging gel; a lead wire I, a lead wire II and a lead wire III are connected outside the packaging gel; the length of the bowl is 0.50-3.00mm and the width is 0.20-2.00mm; the lead wire I and the lead wire II are connected to lighten the wafer B; the lead wire I and the lead wire III are connected to lighten the wafer A; and the lead wire I, the lead wire II and the lead wire III are simultaneously connected to lighten the wafer A and the wafer B. Three light color effects are achieved; a relatively convenient choice is provided for customers; the double-color in-line LED lamp bead is simple in structure; the size miniaturization is achieved; the brightness of an LED can be improved; the double-color in-line LED lamp bead can be applied to combined dimming of various visible light colors on a display screen and has good heat dissipation performance; and the service lifetime of the material is prolonged.

Description

technical field [0001] The invention relates to an LED lamp bead, in particular to a two-color in-line LED lamp bead. Background technique [0002] The full name of LED is semiconductor light-emitting diode. It is made of semiconductor materials and is a light-emitting device that directly converts electrical energy into light energy and electrical signals into optical signals. It is characterized by low power consumption, high brightness, bright colors, anti-vibration, and long life. Long (80,000-100,000 hours of normal light emission), cold light source and other advantages, it is a real "green lighting". In the future of the 21st century, lighting products using LED as the light source will inevitably replace white woven lamps and become another revolution in human lighting. LED lamp beads are widely used in lighting, LED large-screen displays, traffic lights, decorations, computers, and electronic toys. Gifts, switches, telephones, advertisements, city glory projects an...

Problems solved by technology

[0003] At present, the conventional in-line LED is a combination of thermoelectricity, high brightness, good light distribution curve, good angle, and good heat dissipation. It mainly focuses on traditional monochromatic light, but lacks the ability to emit both independent monochromatic light and mixed light. The cost is relatively low. High, difficult for customers to operate, low efficiency, not suitable for dimming power supply
