The invention belongs to the technical field of illumination, and provides an LED control circuit and an LED lamp. The LED control circuit comprises a power supply circuit, a human sensing detection module, a main controller, a driving circuit and a dimming circuit. The human sensing detection module senses approaching of a human body to generate a first sensing signal, the main controller generates a starting signal and a first dimming signal according to the first sensing signal, and the driving circuit generates a first driving voltage according to the starting signal and direct current output by the power supply circuit. The dimming circuit generates a second driving voltage which is gradually increased from zero to the first driving voltage according to the first driving voltage and the first dimming signal, the LED lamp is driven by the second driving voltage to emit light, and when the LED lamp is started, smooth starting from zero to the first driving voltage is carried out through the dimming circuit, so that brightness jump when the LED lamp is started is avoided, and the light-emitting change of the LED lamp is soft and uniform, so that the LED lamp better conforms to the visual characteristics of a human body, and the user experience is improved.
Description
technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to an LED control circuit and an LED lamp. Background technique [0002] At present, traditional LED lights are generally driven by a constant current source, and pulse width modulation (Pulse Width Modulation, PWM) is used to realize the adjustment of different colors and light intensity of the ambient light. [0003] The existing LED light control technology sometimes causes the LED light to flash. When the LED light is switched on or off, the change of the light will have an obvious sense of steps and abruptness, which does not conform to the visual characteristics of the human body. The experience is poor. [0004] Therefore, in the traditional technical solution, there is a problem that when the LED lights are switched on or off, the changes of the lights will have a clear sense of steps and abruptness, which does not conform to the visual characteristics of the h...
