Embodiment approach

[0063] certainly, Figure 5The flow chart in is also just an implementation mode, in fact, if the working mode of the control unit 21 is changed, the LED can be fixed to display a certain color (such as white) when it is powered on for the first time, and then according to the user's The control of the power supply carries out the operation of the above process.

[0064] Obviously, image 3 and Figure 4 The circuit structure in the present invention is only two specific implementations of the controllable LED light emitting device described in the present invention, and the controllable LED light emitting device described in the present invention is not limited to the above embodiments. For example, since the power loss detection can be divided into two types: power voltage detection and power current detection, the power loss detection circuit 23 can also be divided into these two types. image 3 The disclosed power loss detection circuit 23 is a simple voltage detection ...

Abstract

The apparatus comprises: a power supply; a controller connected to the power supply and used for controlling the tricolor LED; an energy storing unit located in the power circuit for use in releasing energy to the control unit when the light emitting apparatus loses energy supply; an electric power failure detecting circuit for detecting the power state and transmitting the power state signals to the controller. The method thereof comprises: when the electrical power is provided, the tricolor LED emits light in a preset order; in the process of alternatively displaying multi colors, if a power failure is detected, then stopping the light emitting from the tricolor LED; when the power is provided again, the tricolor LED locks one color displayed just before the power failure.

Description

technical field [0001] The invention relates to an improved controllable LED lighting device and a lighting control method thereof. Background technique [0002] With the advancement of semiconductor LED (Light Emitting Diode) manufacturing technology, the wide application of LED light emitting devices has become a reality. Most typically, LED lights assembled from red, green, and blue primary color LEDs have been widely used. There are two main types of existing LED lamps: one is a fixed-color LED lamp, which has selected a fixed color through a certain combination during the production process. This type of LED lamp cannot produce any color-changing effect, but can only emit a fixed Good light of a certain color has a single luminous color. When the user needs to change the color of the LED light continuously or change it to another color, it cannot meet the demand due to the monotonous function; thus, there is another LED light on the market. A color-changing LED lamp, ...
