Arbitrary stroboscopic light modulation device

Abstract

The invention belongs to the technical field of light source control, and particularly relates to an arbitrary stroboscopic light modulation device. The device comprises a stroboscopic signal generator, a first group of light sources (CH1) and a second group of light sources (CH2), the stroboscopic signal generator comprises a signal modulation module, a power adjustment module, a waveform displaymodule, a switch module, a signal output module, a power input module, a CH1 output interface and a CH2 output interface. The stroboscopic signal generator can adjust the waveform, frequency, modulation depth, duty ratio and power gain of stroboscopic light according to user requirements; the stroboscopic signal generator is provided with two control paths, independent control of CH1 and CH2 canbe achieved, and synchronous control of signals and power of the two paths can also be achieved. The device plays an important role in researching the influence of human body alertness degree, sleep quality, emotion and the like and other healthy lighting; the device has strong compatibility with a terminal light source, and can meet the application requirements of multiple light sources and different arrangement modes.

Description

technical field [0001] The invention belongs to the technical field of light source control, and in particular relates to an arbitrary stroboscopic light modulation device. Background technique [0002] In the CIE TN2016 technical description document, the temporal light modulation factor in the lighting system is redefined as TLA (temporal light artefacts), that is, in a specific environment, light stimuli such as brightness or spectrum that fluctuate with time cause the visual perception of the observer Its different manifestations are flickering, strobe effect and phantom effect. [0003] Time-modulated light (flicker, strobe) has a significant impact on people's sleep, wakefulness, and fatigue. The latest literature survey results also show that time-modulated light, which is considered to have a negative effect on human health, is also expected to have a certain impact on human health. Certain disease treatments have positive effects. For example, in 2016, Hannah F. Ia...

In addition, a large number of studies have found that under brief flashes, the phase changes of the body clock and the immediate alarm effect can be observed, and flicker phototherapy may develop into an effective method for the treatment of human circadian rhythm disorders

[0004] At present, there are few methods and devices for stroboscopic light modulation, and it is difficult to meet the actual application requirements in the fields of light health and light medicine

For example, the Chinese patent "a light source strobe digital controller, CN 211064017 U" has the advantage of reducing the lighting time of the light source in the form of strobe through instantaneous control of the LED light source, suppressing the internal temperature rise of the LED, thereby greatly extending the The service life of the light source, but the controller cannot accurately control the stroboscopic parameters of the light source, such as: frequency, modulation depth, duty cycle, etc.
