Embodiment Construction

[0037] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0038] like Figure 4-17 As shown, the lighting system of the present invention includes several lighting sources, and the lighting system also includes a control unit for controlling the switching frequency of the lighting sources to be higher than the persistence frequency of human eyes. Here, a brief introduction to persistence of vision is given first to facilitate a better understanding of the present invention.

[0039] Firstly, take the inertia of a car while driving as an example. The fuel consumption of a car is generally determined by the weight of the car and the efficiency of the engine. However, under the same operating conditions, the actual fuel consumption of the car is related to how the driver controls the accelerator. The driving process has kinetic energy and produce...

Abstract

The invention discloses an illumination system, comprising a plurality of illumination light sources and a control unit used for controlling the on-off working frequency of the illumination light sources to be higher than the frequency of persistence of vision of eyes. The invention further discloses an illumination control method of the illumination system; the control unit is used for controlling the on-off working frequency of the illumination light sources so as to lead the on-off working frequency of the illumination light sources to be higher than the frequency of the persistence of the vision of the eyes. Under the precondition of ensuring invariant illumination effect, the invention reduces the power of the light by improving the energy efficiency of the whole light, thereby reducing the power consumption per se and the heat productivity of the light sources and achieving the aims of reducing the cost of the whole light and further saving energy.

Description

technical field [0001] The invention relates to the lighting field, in particular to a lighting system and a lighting control method for improving the energy efficiency of a light source by using the persistence of vision function of the human eye. Background technique [0002] At present, there are three main types of electric light sources: incandescent lamps, low-pressure discharge lamps and high-pressure discharge lamps. These three types of lamps work under the condition of AC 50HZ or 60HZ AC power supply. In addition to high-frequency current power supply, in general, the luminous intensity of the electric light source with AC power supply will also change with the change of the voltage applied to the light source. like Figure 1-3 It is the change curve of the working voltage, lamp power and output light intensity of a typical gas discharge lamp. [0003] In order to obtain higher light intensity and better lighting effects, high-efficiency light sources and high-eff...
