LED (Light-Emitting Diode) light source and working method thereof

Abstract

The invention discloses an LED light source and a working method thereof. The light source comprises a disk, a lampshade, a singlechip, a control circuit, a small electromotor and a power supply, wherein the disk and the lampshade form a top-shaped lamp shell, an LED lamp group is inlaid on the disk, the LED lamp group comprises red LED lamps, yellow LED lamps and blue LED lamps, the singlechip, the control circuit, the small electromotor and the power supply are respectively installed in the lamp shell, and the singlechip is respectively connected with the LED lamps, the small electromotor and the power supply through the control circuit. In the invention, the singlechip is used for circuit control to respectively lighten the red LED lamps, the yellow LED lamps and the blue LED lamps which are inlaid on the disk. When the three colors of lamps are all lightened, white light with softer hue can be emitted. Brightness control is realized by controlling the rotating speed of the small electromotor. The on-off proportion of the LED lamps of different colors is controlled through the singlechip, thereby the hue of the emitted light can be continuously controlled.

Description

technical field [0001] The invention relates to a light source, in particular to an LED light source and its working method. Background technique [0002] Due to the following inherent characteristics of the LED light source, it is the most ideal light source to replace the traditional light source, and it has a wide range of uses. [0003] 1. Small size. An LED is basically a tiny chip encapsulated in epoxy, so it's very small and very light. [0004] 2. Low power consumption. LED power consumption is very low. Generally speaking, the working voltage of LED is 2-3.6V, and the working current is 0.02-0.03A. That is to say: it consumes no more than 0.1W of electricity. [0005] 3. Long service life. Under the right current and voltage, the life of LED can reach 100,000 hours. [0006] 4. High brightness and low heat. Less heat radiation than HID or incandescent. [0007] 5. Environmental protection. LEDs are made of non-toxic materials, unlike fluorescent lamps that ...

AI Technical Summary

Problems solved by technology

[0011] 1. The white light produced has a high color temperature, a single tone, and the brightness of the white light cannot be adjusted, which is irritating to the human eye;

[0012] 2. The process of preparing white light is very difficult
