Human eye light adaptation simulating intelligent lamplight device and air testing equipment

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...

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 of people's living standards, environmental pollution has become increasingly serious, especially indoor air quality has gradually attracted people's attention. People spend about 80% of their time indoors a day, and indoor PM2.5 (PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere), TVOC (the English abbreviation of olatileOrganicCompound, all indoor organic gaseous substances sampled and analyzed are called TVOC) and other harmful substances are seriously endangering people's health; at present, There are many types of air detection equipment on the market, but they are relatively simple in terms of function. They only have a single type of air information display function, and the price is high, and they do not have intelligent lighting functions.
