Problems solved by technology

But this kind of light has certain limitations. Firstly, this kind of dimming can only be used for halogen lamps, and the production and use of halogen bulbs are restricted by many countries due to their high energy consumption; secondly, this kind of dimming can only be done manually. It is inconvenient to use

Embodiment Construction

[0017] Describe the circuit realization of the present invention in detail below according to the example, as appended figure 2 As shown, the specification of wall switch (11) is 10A220V; the type of diode (12) is IN4007; (13) and (19) use AC220V to DC12V 300mA power supply module; (14) and (17) use NMOS tube as switch; relay (15) The specification is 12V 10A; (16) 555 delay circuit is used; the circuit (18) is composed of a diode and a relay. What the circuit (20) used is a diode, so that after the switch is disconnected, the power module (13) continues to work; the specification of the power module (22) is AC220V to DC12V / 2A; The lamp signal; the central processing unit (24) is implemented with a single-chip microcomputer; the circuit (25) uses an NMOS tube to perform the gradual brightening and dimming of the lamp; the backup power supply (26) uses a group of 1000uF / 25V electrolytic capacitors to realize the delay. The circuit execution flow is as follows:

Abstract

In a specific light environment for a long time, human eyes can adapt to the specific light environment. Sudden darkness or strong light can affect people's vision and the human eyes need time to readapt to the new light environment. The invention discloses an LED lighting fade-in and fade-out control method. The method relates to technical solutions about the fade-in and fade-out light change ina lighting system when a light is turned on or off, turn-off signal transmission and detection, and turn-off delayed power off. As shown in the Figure 1, by means of the innovative design of a switchcontrol part, a transmission line and a lamp circuit part in an existing LED control system, when a switch in the switch control part is turned on or off, the light is changed gradually so as to the improve the comfort of the human eyes, give full scope to the advantages of LED lighting, and promote LED lighting technology in the lighting market.

Description

technical field [0001] The invention belongs to the technical field of lighting automatic control, and the method relates to technical schemes such as the change of the way of light fading and dimming when the light is turned on and off in the lighting system, the signal transmission and detection of the light off, and the power-off delay when the light is turned off. Background technique [0002] After turning on the light in the dark night, the sudden brightening light will hurt the eyes very uncomfortable; after turning off the light, the eyes suddenly become dark, and it takes a long time for the eyes to recover, which makes people feel uncomfortable. "Big Technology·Science Mystery" expounds this way: in a specific bright environment for a long time, the human eye will adapt to this specific bright environment. Sudden darkness or strong light will affect people's vision. Your eyes take time to readjust. When the strong light suddenly hits the eyes, the photosensitive p...
