Document Type and Number:
WIPO Patent Application WO/2024/016565
Kind Code:
A1
Abstract:
A light source (1), a bulb and a lamp. The light source (1) comprises an LED multicolor lamp strip (20), a tube body (101), a light pattern controller (21), and a power supply system (22). The LED multicolor lamp strip (20) is electrically connected to the light pattern controller (21); the light pattern controller (21) is electrically connected to the power supply system (22); the LED multicolor lamp strip (20) is wound and distributed on the tube body (101) along a predetermined spiral path and extends in the axis direction of the tube body (101). The LED multicolor lamp strip (20) comprises a strip body (103), a peripheral circuit (102) laid on the strip body (103), and a plurality of LED multicolor lamp beads (104) linearly arranged on the strip body (103). The plurality of LED multicolor lamp beads (104) are each provided with a built-in or external IC control chip, and are each electrically connected to the light pattern controller (21) by means of the peripheral circuit (102), so that the plurality of LED multicolor lamp beads (104) separately receive an instruction of the light pattern controller (21) and then emit light, forming a 360° annular two-dimensional color light pattern of the tubular light source.
