Intelligent control background lamp of TV set

Abstract

An intelligent control back ground lamp of TV set belonging to TV set technical field includes luminous devices and their control circuit, of which the control circuit consists of photosensitive resistance photosensing circuit, resistance / voltatge converting circuit, voltage stabilization circuit and amplifying circuit, central processor of TV set, impedance matching box, photoelectric isolator, two-way silicon controlled AC voltage regulator and series circuit of AC power source and luminous devices. The resisting / voltage converting circuit and amplifying circuit as well as impedance matching box with the be composed by arthmetic mplifiers and the photoelectric isolator will be formed by photoelectric coupler, luminous device will be one of fluorescent lamp, filament lamp of iodine-tungsten lamp and the two-way silicon controlled AC coltage regulator will be composed by one-way simplexer and two-way thyristor. According to the peripheral circumstance lightnss, the lamp lightness can be regulated autoamtically and freely by TV set or remote-controllor in order to have an indeeal screen image and to protect the sight.

Description

technical field [0001] The invention belongs to the technical field of television sets, and more specifically relates to an intelligent control background light of a television set which relates to ancillary equipment of the television set. Background technique [0002] The vast majority of current televisions are not directly related to the ambient background light in which they are placed. That is to say, whether it is day or night, people watching TV can at most adjust the brightness or contrast of the TV to adapt to the intensity of ambient light and improve the screen image. The result is often: dazzling during the day due to stronger light, and dazzling at night due to weaker light. Over time, it can easily lead to visual fatigue and vision loss. [0003] The patent No. 90218326.5 "TV Lighting Health Care Lamp" provides a background light with adjustable direction for viewers. But it is independent from the TV set and needs to be adjusted...

Problems solved by technology

But none of them can adjust the brightness of the light at will, let alone automatically adjust the brightness of the light or the contrast of the TV, so that the viewers cannot always be in the ideal light background.

It can not achieve the purpose of not only enabling the viewers to watch the ideal screen image, but also protecting their eyesight
