Abstract

The invention relates to a two-color temperature flexible filament and a packaging method thereof. The two-color temperature flexible filament comprises a flexible substrate, two parallel circuits distributed on the flexible substrate, two groups of flip-chip LED chips parallelly distributed on the flexible substrate and connected with the two circuits respectively, a low-color temperature silicagel phosphor mixture coating the front and the back of any group of flip-chip LED chips and a high-color temperature silica gel phosphor mixture coating the front and the back of the other group of flip-chip LED chips. According to the two-color temperature flexible filament and the packaging method thereof disclosed in the invention, two circuit parts are designed, and after chips are fixed, thechips are directly coated with two silica gel and phosphor mixtures with different color temperatures, and the two-color temperature effects are achieved; and the two circuits can be designed with different voltage, filaments with two color differences and different voltage can be designed according to driving power supply requirements of a client, the production process of the two-color temperature flexible LED filament can be simplified, and the production efficiency and the yield can be improved.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a flexible filament with two color temperatures and a packaging method thereof. Background technique [0002] With the gradual withdrawal of ordinary incandescent lamps from the lighting market, LED lighting sources are rapidly occupying the entire lighting market. Most of the LED lighting sources use light-emitting diodes as light sources. Light-emitting diodes are solid-state semiconductor devices that can convert electrical energy into visible light. It can directly convert electrical energy into visible light. The core of the LED is a light-emitting diode chip, one end of which is the negative pole, and the other end is the positive pole connected to the power supply. Flexible filaments are used as lighting or decorative lamps. Because their shapes are similar to incandescent lamps that are widely available in the market, under the environment of vigorously promoti...
