Problems solved by technology

[0003] The existing RGB color mode LED lamp control technology sometimes causes the LED lamp to flash. When the LED lamp is lit, adjusted brightness, extinguished or the color is switched, the change of the light will have an obvious sense of step and abruptness, which is not in line with Due to the visual characteristics of the human body, the user experience is poor, and the sudden change of light can easily distract the driver's attention, which may bring safety hazards

Embodiment

[0072] See figure 1 , figure 1 It is a flowchart of a method for controlling the lighting of an LED lamp provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0073] Step S101, receiving a control message;

[0074] Specifically, the control message is received from the on-board main controller. When the vehicle-mounted main controller detects the user's operation and determines to control the LED light according to its own logic, it sends the control message to the LED light controller.

[0075] Step S102: parse the control message to determine the control mode and control target value of the LED lamp;

[0076] Specifically, the control mode of the LED lamp includes a lighting mode (a mode from off to on), a brightness adjustment mode, an off mode (a mode from on to off), and a toning mode.

[0077] Specifically, the control target value includes a three-color target duty cycle, that is, a red target duty cycle, a green target duty cycle...

Abstract

The invention discloses a lighting control method, device and system of an LED lamp. The method includes: receiving a control message; parsing the control message to determine the control mode and control target value of the LED lamp; the control mode of the LED lamp includes a lighting mode, a brightness adjustment mode, an extinguishing mode and a dimming mode. color mode; the control target value includes a three-color target duty ratio; determine the luminescence gradient parameter corresponding to the control mode of the LED lamp, and calculate the luminescence gradient parameter corresponding to the luminescence gradient parameter in the dimming process of the LED lamp Gradual PWM duty cycle; the value range of the light-emitting gradient parameter is [0.005,0.05]; the output duty cycle is the PWM signal of the gradual PWM duty cycle to the driver to control the LED lamp to emit light gradually, and the The frequency of the PWM signal is greater than 100 Hz. The present invention can realize soft and uniform luminous changes of LED lamps, thereby more conforming to the visual characteristics of the human body and improving user experience.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a method, device and system for controlling the light emission of an LED lamp. Background technique [0002] At present, RGB color mode LED (Light Emitting Diode, light-emitting diode) lights can be used for smart atmosphere lights of vehicles. RGB color mode LED lights are generally driven by a constant current source and PWM (Pulse Width Modulation) is used to realize the atmosphere lights. The adjustment of different colors and light intensity. [0003] The existing RGB color mode LED light control technology sometimes causes the LED light to flash. When the LED light is turned on, adjusted brightness, extinguished, or color is switched, the change of the light will have an obvious sense of step and suddenness, which is not consistent. The visual characteristics of the human body make the user experience poor, and sudden changes in light can easily distract the driver, w...
