Problems solved by technology

[0002] In low-light and dark environments, the human eye sees all gray-black scenes, and the human eye is in the state of dark vision at this time, but if the light intensity changes suddenly (such as turning on an ordinary incandescent lamp in the room), due to the physiological mechanism function, the human eye cannot immediately perceive and adapt to the brightness change of the environment, the human eye has a time delay and brightness response process
In terms of the brightness of the light, it is not good if the light is too strong or too dark. When the strong light is turned on, it often takes a while for the eyes to adapt. The light that is too dark makes people unable to see clearly and easily leads to eye fatigue.
[0003] Furthermore, with the development of society and the improvement o...

Embodiment 1

[0034] Such as figure 1 and Figure 10 As shown, an intelligent lighting device that simulates the adaptation of human eyes includes a CPU module. The CPU module in this embodiment includes an STM32F103R8T6 chip and its peripheral circuits. It also includes an ambient light detection module, an illuminator start module and an illuminator module electrically connected to the CPU module, wherein the ambient light detection module is used for real-time detection of ambient light, and converts the collected light into a voltage signal and transmits it to the CPU Module, wherein the illuminator start module transmits the electrical signal to light the illuminator to the CPU module, and the illuminator module receives the PWM pulse signal transmitted by the CPU module, and after receiving it, gives the illuminator a certain current according to the PWM pulse signal to make it emit light of a certain intensity.

[0035] Such as figure 2 As shown, the intelligent lighting device s...

Embodiment 2

[0043] Such as figure 1 and Figure 10 As shown, an air detection device includes the above-mentioned intelligent lighting device for simulating human eyesight adaptation, and also includes an air detection module electrically connected to the CPU module of the intelligent lighting device for simulating human eyesight adaptation. The air detection module of this embodiment includes a PM2.5 sensor, a TVOC sensor, a humidity sensor and / or a temperature sensor, and each sensor is communicatively connected with the CPU module through an independent communication port. The air detection device of the embodiment also includes a display screen electrically connected to the CPU module and a power supply electric quantity detection module, and the above-mentioned display screen is preferably a TFT display screen (ultra-thin notebook display screen).

[0044] Such as Figure 7 As shown, the working principle of the above-mentioned power supply detection module is: a pin of the CPU mod...

Abstract

The invention discloses a human eye light adaptation simulating intelligent lamplight device and air testing equipment. The intelligent lamplight device comprises a CPU (Central Processing Unit) module, an ambient light detecting module, a light emitter starting module and a light emitter module, so that the intelligent lamplight device can acquire ambient lights in real time and can adjust a duty ratio of a PWM (Pulse-Width Modulation) signal of the CPU module for lighting up a light emitter in real time based on the lights when the light emitter is turned on, and human eyes can be prevented against highlight stimulation during a period of time and can adapt to the environment in a certain time. The air testing equipment provided with the intelligent lamplight device comprises an air testing module which is electrically connected with the CPU module, so that the air testing equipment which is provided with a light part based on a light and dark adaptation process of human eye perception characteristics can dynamically test and display multiple indoor air quality information. The human eye light adaptation simulating intelligent lamplight device is applicable for devices which are used at home, offices and other indoor places, can perform lamplight brightness adjustment based on the human eye light adaptation and have an air information function.

Description

technical field [0001] The invention relates to the technical field of light perception transmission for human eyesight adaptation, in particular to an intelligent lighting device and air detection equipment for simulating human eyesight adaptation. Background technique [0002] In low-light and dark environments, the human eye sees all gray-black scenes, and the human eye is in the state of dark vision at this time, but if the light intensity changes suddenly (such as turning on an ordinary incandescent lamp in the room), due to the physiological mechanism As a result, the human eye cannot immediately perceive and adapt to changes in the brightness of the environment. The human eye has a time delay and brightness response process. In terms of the brightness of the light, it is not good if the light is too strong or too dark. When the strong light is turned on, it often takes a while for the eyes to adapt. Too dark light makes people unable to see clearly and easily leads to...
