Abstract
The utility model relates to a temperature regulating device of an electric torch, which is characterized by comprising a temperature measuring unit and a current control unit. The temperature measuring unit is arranged in a shell of the electric torch, the current control unit is electrically connected with the temperature measuring unit, and current supplied for a luminous element of the electric torch is regulated by the current control unit according to the temperature, which is measured by the temperature measuring unit, of the electric torch. The temperature of the electric torch is measured by the temperature measuring unit, the current of the luminous element is controlled according to the measured temperature, accordingly, the temperature of the electric torch is regulated, and the service life of the electric torch is prolonged.
Description
Technical field
The utility model relates to lighting field, particularly a kind of flashlight and temperature-adjusting device thereof.
Background technology
In the prior art, when flashlight is long-time use after, the temperature in the flashlight can constantly raise because the rising of temperature, can shorten light-emitting component (like the LED lamp) service life, reduce the reliability of flashlight.
The utility model content
Thereby the utility model provide a kind of simple in structure, dependable performance, cost low, can realize thermoregulator flashlight and temperature-adjusting device thereof according to the electric current that variation of temperature is regulated light-emitting component.
For solving the problems of the technologies described above, the utility model provides a kind of temperature-adjusting device of flashlight, it is characterized in that, comprising: temperature measurement unit, said temperature measurement unit are arranged in the housing of said flashlight; Current control unit, said current control unit is electrically connected with said temperature measurement unit, and the adjustment of the said flashlight that said current control unit records according to said temperature measurement unit is supplied with the electric current of the light-emitting component of said flashlight.
Further, said temperature measurement unit comprises temperature sensor.
The utility model also provides a kind of flashlight, it is characterized in that, comprises above-mentioned temperature-adjusting device.
The utility model is measured the temperature of flashlight through its temperature measurement unit, and through the temperature that the records electric current to the control light-emitting component, thereby realized adjusting to the flashlight temperature, improved the service life of flashlight.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Fig. 2 is thermostatic structural representation.
The specific embodiment
Shown in Fig. 1-2, the temperature-adjusting device of the flashlight in the utility model comprises: temperature measurement unit 3, said temperature measurement unit 3 are arranged in the housing 2 of said flashlight 1; Said temperature-adjusting device also comprises the current control unit (not shown); Said current control unit is electrically connected with said temperature measurement unit 3, and the adjustment of the said flashlight 1 that said current control unit records according to said temperature measurement unit 3 is supplied with the electric current of the light-emitting component (not shown) of said flashlight 1.Therefore, in the use of flashlight, can respond to the temperature in the flashlight automatically through said temperature measurement unit 3.For example, when temperature surpassed predetermined a certain value, said current control unit reduced the electric current of supplying with said light-emitting component, thereby made the temperature in the flashlight drop to the rational temperature scope, with the service life of the light-emitting component of raising flashlight.
Preferably, said temperature-adjusting device comprises circuit board 4, and said temperature measurement unit comprises temperature sensor 5, and said temperature sensor 5 is arranged on the said circuit board 4.
As the utility model on the other hand, the utility model also provides a kind of flashlight, and it comprises above-mentioned temperature-adjusting device.
The utility model is measured the temperature of flashlight through its temperature measurement unit, and through the temperature that the records electric current to the control light-emitting component, thereby realized adjusting to the flashlight temperature, improved the service life of flashlight.
