Description
Technical field
The utility model relates to household electrical appliance technical field, particularly a kind of TV background luminance adjusting device.
Background technology
When seeing TV in daily life, whether the appropriateness that has that it's too late of background light, can form different visual effects, and cause different impacts to the perception of beholder.In current family, mostly the acquisition of TV background light is to be provided by the illuminating lamp in room, due to the general all immutable brightness of illuminating lamp, therefore the brightness of TV background light mostly also is invariable, this situation cannot match with the change of TV display brightness undoubtedly, beholder can be caused can not to obtain good viewing experience, therefore design and a kind ofly the device of TV background light luminance can be regulated to seem necessary with the change of TV display brightness.
Utility model content
In view of this, the utility model is intended to propose a kind of TV background luminance adjusting device, changes with the change of TV display brightness with the brightness realizing TV background light, thus promotes the viewing experience of beholder.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of TV background luminance adjusting device, it comprises the first brightness detection module being arranged at television display screen front, be electrically connected on the control module of described first brightness detection module, and be electrically connected on the background light in described control module via voltage regulator.
Further, also comprise the second brightness detection module being located at television background wall place, the comparator be electrically connected with described first brightness detection module and the second brightness detection module, described comparator is electrically connected on control module.
Further, described first brightness detection module is the multiple luminance sensors being arranged in television display screen front, described second brightness detection module is the multiple luminance sensors being arranged in television background wall place, is serially connected with the first calculator and the second calculator respectively at described comparator with between the first brightness detection module and the second brightness detection module.
Further, the luminance sensor of described first brightness detection module is three of the position, left, center, right being arranged at television display screen front respectively.
Further, the luminance sensor of described second brightness detection module is three that are arranged at position, television background wall left, center, right respectively.
Further, described background light is via multiple on television background wall of three, left, center, right angular illumination.
Further, described multiple background lights have different colors.
Relative to prior art, the utility model has following advantage:
(1) TV background luminance adjusting device described in the utility model, television set display brightness is detected by the first brightness detection module, then can be regulated the brightness of background light by control module according to television set display brightness, thus the brightness of motor background light and the display brightness of television set can be made to match, avoid the contrast of brightness between the two to bring the sense of discomfort of beholder, improve the viewing experience of beholder.
(2) closed-loop adjustment that the second brightness detection module and comparator can realize TV background luminance is set, thus the better matching ensureing background luminance.
(3) make the first brightness detection module and the second brightness detection module all be set to be positioned at three of position, left, center, right, the reliability that brightness detects can be improved.
(4) background light is set to multiple control effects that also can improve background luminance of irradiating in different angles, and background light has different colors can the texture of background luminance further.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structure configuration diagram of the TV background luminance adjusting device described in the utility model embodiment;
Description of reference numerals:
1-first brightness detection module, 2-second brightness detection module, 3-comparator, 4-control module, 5-voltage regulator, 6-first calculator, 7-second calculator, 8-background light.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
In addition, the position, left, center, right mentioned in embodiment of the present utility model, refers to the visual angle from beholder, is positioned at the left side at television set front or wall place, centre and position, three, right side.Certainly except can be the situation under above-mentioned visual angle, left side wherein, right positions also can exchange, and these two kinds of situations are in fact identical in the present embodiment.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
The present embodiment relates to a kind of TV background luminance adjusting device, as shown in fig. 1, it comprises the first brightness detection module 1 being arranged at television display screen front, be electrically connected on the control module 4 of the first brightness detection module 1, and be electrically connected on the background light 6 in control module 4 via voltage regulator 5.First brightness detection module 1 is for being arranged in multiple luminance sensors in television display screen front.The television set display brightness that control module 4 can detect according to luminance sensor, the adjustment realized background light 6 luminosity by the output voltage of control voltage adjuster 5.
In the present embodiment, background light 6 can be set to via multiple on television background wall of three, left, center, right angular illumination, such as three, and the color of each background light 6 can also be designed to different, can improve the texture of irradiating light on television background wall.Simultaneously, in order to improve the matching of background light 6 luminosity and television set display brightness, also can the second brightness detection module 2 be set at television background wall place in the present embodiment, and the comparator 3 to be all electrically connected with the first brightness detection module 1 and the second brightness detection module 2, the output of comparator 3 is electrically connected in control module 4.
Second brightness detection module 2 is also for being arranged in multiple luminance sensors at television background wall place, luminance sensor in the present embodiment in the second brightness detection module 2 can be three that are arranged at position, television background wall left, center, right respectively, and the luminance sensor in the first brightness detection module 1 also can be three of the position, left, center, right being arranged at television display screen front respectively.Luminance sensor in certain first brightness detection module 1 and the second brightness detection module 2 above-mentioned is set to except three except can be, and it also can be set to as one, other quantity such as two or four.
