Abstract
The utility model relates to a flashlight and a brightness control device thereof. The brightness control device is characterized by comprising an angle measuring unit and a glow brightness control unit, wherein the angle measuring unit is arranged in a shell of the flashlight, and the glow brightness control unit is electrically connected with the angle measuring unit and used for controlling the brightness change of a light-emitting element of the flashlight according to the inclination angle of the flashlight measured by the angle measuring unit. The inclination angle of the flashlight is measured by the angle measuring unit, and the brightness of the flashlight is adjusted according to the measured inclination angle, so that practicability and intelligence of the flashlight are improved.
Description
Technical field
The utility model relates to lighting field, particularly a kind of flashlight and brightness controlling device thereof.
Background technology
The brightness of flashlight of the prior art can not change, yet, because the user need use flashlight to illuminate the zone of different far and near distances, thereby, when the user is shone closer distance regional, if brightness is excessive, the phenomenon of presbyopia can take place; And when the user is shone longer-distance zone, if still use same brightness, so then can not clearly observe owing to distance is far away, light is more weak.
The utility model content
The utility model provides flashlight and the brightness controlling device thereof that a kind of simple in structure, dependable performance, cost are low, can regulate brightness according to the variation at inclination angle.
For solving the problems of the technologies described above, the utility model provides a kind of brightness controlling device of flashlight, it is characterized in that, comprising: the angular surveying unit, and said angular surveying unit is arranged in the housing of said flashlight; The luminosity control module; Said luminosity control module is electrically connected with said angular surveying unit, and the brightness that the light-emitting component of said flashlight is controlled at the angle of inclination of the said flashlight that said luminosity control module records according to said angular surveying unit changes.
Further, said angular surveying unit comprises obliquity sensor.
Further, said obliquity sensor is an acceleration transducer.
The utility model also provides a kind of flashlight, it is characterized in that, comprises above-mentioned brightness controlling device.
The utility model is measured the inclination angle of flashlight through its angular surveying unit, and through the inclination angle value that records its brightness is regulated, thereby has improved the practicality of flashlight and intelligent.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Fig. 2 is the structural representation of brightness controlling device.
The specific embodiment
Shown in Fig. 1-2, the brightness controlling device of the flashlight in the utility model comprises: angular surveying unit 3, said angular surveying unit 3 are arranged in the housing 2 of said flashlight 1; Said brightness controlling device also comprises luminosity control module (not shown); Said luminosity control module is electrically connected with said angular surveying unit 3, and the brightness that the light-emitting component (not shown) of said flashlight 1 is controlled at the angle of inclination of the said flashlight 1 that said luminosity control module records according to said angular surveying unit 3 changes.Therefore, when the hand-held flashlight of user threw light on, flashlight just can be responded to the hand-held angle of flashlight automatically through said angular surveying unit 3.When the user is used for illuminating the zone, underfooting straight down with flashlight; The inclination angle that angular surveying unit 3 can detect flashlight immediately changes; And the inclination angle that it records sent to said luminosity control module, at this moment, under the control of said luminosity control module; The brightness of flashlight 1 reduces automatically, to prevent that brightness is too high and penetrate colored user's eyes; When the user with flashlight by vertical downwards direction lentamente to horizontal direction deflection illuminate pin the place ahead to the time; Said luminosity control module can detect the variation of its angle through angular surveying unit 3; And the brightness that improves the light-emitting component of flashlight gradually, adapt to illumination slightly at a distance with this; When flashlight during more near horizontal level, its distance that illuminates is far away more, and at this moment, the brightness of flashlight also can be high more, so just can make the user see farther distance clearly through higher brightness; As user during with flashlight directive sky, said luminosity control module transfers to the brightness of flashlight the brightest automatically.Thus it is clear that, can regulate its brightness according to the angle of flashlight through the utility model, thereby improve the practicality of flashlight and intelligent.
Preferably, said angle controller comprises circuit board 4, and said angular surveying unit comprises obliquity sensor 5, and said obliquity sensor 5 is arranged on the said circuit board 4.Preferably, said is acceleration transducer.
As the utility model on the other hand, the utility model also provides a kind of flashlight, and it comprises above-mentioned brightness controlling device.
The utility model is measured the inclination angle of flashlight through its angular surveying unit, and through the inclination angle value that records its brightness is regulated, thereby has improved the practicality of flashlight and intelligent.
Claims (4)
