Abstract
The utility model provides a kind of device according to video screen automatic brightness adjustment indoor light, belongs to the field such as electronics, optics, comprises luminance sensor module, LED light modulating device module.The data output end of luminance sensor module connects the data input pin of LED light modulating device module.This device major function is dead ahead luminance sensor being placed in screen, the position of this sensor should be placed on can accurate acquisition screen intensity position and the interference of surround lighting can be reduced.The beholder of TV selects the room brilliancy be suitable for, by confirming that button is remembered in the apparatus.The brightness of illumination of indoor is followed the tracks of video screen by LED light modulating device automatically.Keep this luminance difference approximately constant as much as possible.Thus ensure optimal brightness ratio.
Description
Technical field
Belong to the field such as electronics, optics, relate to light sensor technology, be applied to according to video screen automatic brightness adjustment indoor light.
Background technology
In the light environment of constant brightness, people are when watching TV programme, it is dim when different scenes causes video screen, time and become clear, so long-time light and shade alternately can cause user's ophthalmic uncomfortable, but intensity of light and video screen brightness exist and certain determine ratio and effectively can alleviate video screen brightness to the stimulation of human eye and injury in viewing environment, but due to video screen brightness be moment conversion, the brightness of indoor fluorescent tube is comparatively fixing.Of the present utility model appearance is intended to head it off, according to video screen automatic brightness adjustment indoor light, can ensure optimal brightness ratio, the enjoyment amusement time enabling people comfortable.
Utility model content
The purpose of this utility model is to provide a kind of based on light sensor technology and device, realizes the function according to video screen automatic brightness adjustment indoor light.
The utility model hardware is made up of luminance sensor module, LED light modulating device module.
The technical solution of the utility model: comprise luminance sensor module, LED light modulating device module.The data output end of luminance sensor module connects the data input pin of LED light modulating device module.This device major function is dead ahead luminance sensor being placed in screen, the position of this sensor should be placed on can accurate acquisition screen intensity position and the interference of surround lighting can be reduced.The beholder of TV selects the room brilliancy be suitable for, by confirming that button is remembered in the apparatus.The brightness of illumination of indoor is followed the tracks of video screen by LED light modulating device automatically.Keep this luminance difference approximately constant as much as possible.Thus ensure optimal brightness ratio.
the advantage that the utility model has: 1. simple to operate, it is unique to experience; 2. simple installation, compact.
Accompanying drawing explanation
Fig. 1 is block diagram of the present utility model; Fig. 2 is configuration schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises luminance sensor module, LED light modulating device module, when luminance sensor module is placed in the dead ahead of screen by user when seeing TV, and be placed on can accurate acquisition screen intensity position and the interference of surround lighting can be reduced, the beholder of TV selects the room brilliancy be suitable for, by confirming that button records indoor brightness of illumination to the luminance difference of video screen in luminance sensor, this luminance difference is sent to LED light modulating device module simultaneously, LED light modulating device keeps this luminance difference approximately constant by regulating room brilliancy, thus ensure optimal brightness ratio,
Described luminance sensor module, be placed in the dead ahead of screen, the position of this sensor be placed on can accurate acquisition screen intensity position and the interference of surround lighting can be reduced, the beholder of TV selects the room brilliancy be suitable for, by confirming that button is remembered in the apparatus;
The brightness of illumination of indoor can be followed the tracks of video screen by described LED light modulating device module automatically, keeps this luminance difference approximately constant as much as possible, thus ensures optimal brightness ratio;
As shown in Figure 2, when luminance sensor module 1 is placed in the dead ahead of screen by user when seeing TV, and be placed on can accurate acquisition screen intensity position and the interference of surround lighting can be reduced, the beholder of TV selects the room brilliancy be suitable for, by confirming that button records indoor brightness of illumination to the luminance difference of video screen in luminance sensor module 1, this luminance difference is sent to LED light modulating device module 2 simultaneously, LED light modulating device module 2 keeps this luminance difference approximately constant by regulating room brilliancy, thus ensure optimal brightness ratio, after setting, user is when watching TV, if video screen brightens suddenly, light sensor module 1 finds out corresponding lamplight brightness after monitoring, now light is just transferred to required brightness by LED light-adjusting module 2, vice versa.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
