The embodiment of the invention provides a kind of photosensitive formula button that is used for calorimeter; Wherein, This light control device that is used for the photosensitive formula button of calorimeter advances the control switch that optical channel is opened or closed for the control optical pickup apparatus; Generally, this control switch controls into optical channel and cuts out, and promptly advancing the optical channel normality is closed condition.When this control switch was controlled into optical channel and opened, optical pickup apparatus received conducting behind the light of outside incident, is equivalent to button and is pressed; This control switch is controlled when into optical channel is closed, and optical pickup apparatus does not end after receiving the light of outside incident, is equivalent to button and upsprings, and realizes keypress function thus.
Particularly, optical pickup apparatus can receive the visible light, ultraviolet light, infrared light of outside incident etc., corresponding, optical pickup apparatus can be common light-inductive pipe, UV photosensitive induction tube or infrared light-inductive pipe.
Yes need explanation, the light-inductive pipe in the embodiment of the invention can be photodiode or phototriode.
In addition, under normal conditions, control switch should control into that optical channel is in closed condition, is in the state of upspringing to guarantee the photosensitive formula button that generally is used for calorimeter.
The embodiment of the invention provides a kind of photosensitive formula button that is used for calorimeter; Wherein, This light control device that is used for the photosensitive formula button of calorimeter is the control switch that is arranged on the light emitting devices, and whether said switch control light emitting devices is to optical pickup apparatus emission light.In the present embodiment, optical pickup apparatus is the light-inductive pipe, and light emitting devices is a light-emitting diode, and the part that the light-inductive pipe exposes cured layer covers through big envelope to be opened/closed, and said light control device is the control switch that said sealing shroud opens and closes.
This control switch control light emitting devices is launched the light time to optical pickup apparatus, and optical pickup apparatus receives conducting behind the light of light emitting devices emission, and the photosensitive formula button that is equivalent to be used for calorimeter is pressed; Optical pickup apparatus does not end after receiving the light of light emitting devices emission, and the photosensitive formula button that is equivalent to be used for calorimeter is upspring, and realizes keypress function thus.
Particularly, light emitting devices can be a light-emitting diode, specifically can comprise common light-emitting diode, UV LED and infrarede emitting diode; Correspondingly, optical pickup apparatus can be the light-inductive pipe, specifically can comprise common light-inductive pipe, UV photosensitive induction tube and infrared light-inductive pipe; In addition, the light emitting devices in the embodiment of the invention can also be luminescent devices such as semiconductor laser.
Need to prove; Because common light-inductive pipe (comprising photodiode or phototriode) mainly receives visible light; The main visible emitting of light-emitting diode; Therefore in visible-range, can't use the photosensitive formula button of forming by common light-inductive pipe and common light-emitting diode that is used for calorimeter, but such photosensitive formula button that is used for calorimeter can be applied in the application circumstances that does not have visible light.
In addition; Owing to contain ultraviolet composition in the visible light; If comprise the UV photosensitive induction tube that receives ultraviolet light so be used for the photosensitive formula button of calorimeter; Then such photosensitive formula button that is used for calorimeter had better not use at the visible light application environment, otherwise can influence the overall performance that such is used for the photosensitive formula button of calorimeter, still can be applied in the applied environment that does not have visible light and ultraviolet light preferably but this type is used for the photosensitive formula button of calorimeter.
In one embodiment of the invention, the photosensitive formula button that is used for calorimeter can comprise infrared light-inductive pipe and infrarede emitting diode, and the photosensitive formula button that this type is used for calorimeter can be applied in most applied environments; With respect to the above-mentioned two types photosensitive formula button that is used for calorimeter, such applied environment of photosensitive formula button that is used for calorimeter is more extensive.
Need to prove that in other embodiments of the invention, this light control device that is used for the photosensitive formula button of calorimeter can both comprise the control switch that control is advanced the optical channel unlatching or closed, and can comprise the control switch that is arranged on the light emitting devices again.Particularly, can only open control switch that the control optical pickup apparatus advances optical channel makes light incide optical pickup apparatus to realize keypress function; Also can only open the control light emitting devices to the radiative control switch of optical pickup apparatus, make light emitting devices realize keypress function to optical pickup apparatus emission light.
To before the photosensitive formula button that is used for calorimeter that comprises infrared light-inductive pipe and infrarede emitting diode mentioned, below make concrete introduction.Fig. 5 and Fig. 6 are respectively circuit structure diagram and the circuit structure diagram of optical pickup apparatus of light emitting devices that infrarede emitting diode and infrared light-inductive pipe are used for the photosensitive formula button of calorimeter.
The positive pole of infrarede emitting diode 301 links to each other with the positive pole of battery V through resistance R, and the negative pole of infrarede emitting diode 301 links to each other with the negative pole of battery V through switch 302; The plus earth of infrared light-inductive pipe 401, the negative pole of infrared light-inductive pipe 401 links to each other with power supply through resistance R.In addition, capacitor C of all right parallel connection in the two ends of infrared light-inductive pipe 401, this is because infrared light-inductive pipe receives the moment conducting of infrared signal, can produce signal jitter, this capacitor C can be removed signal jitter.
The operation principle of the photosensitive formula button that is used for calorimeter of this structure is following: the infrared signal of a certain time of 301 pairs of infrared light-inductive pipes shown in Figure 6 of infrarede emitting diode shown in Figure 5,401 emissions; When infrared light-inductive pipe 401 receives this infrared signal; Infrared light-inductive pipe 401 conductings; There is electric current to flow through, is equivalent to button and is pressed.After infrarede emitting diode 301 stopped to launch infrared signal, infrared light-inductive pipe 401 ended, and does not have electric current to flow through, and this process is equivalent to button and upsprings.Just infrared light-inductive pipe 401 receives infrared signal and just is equivalent to button and is pressed; Stopping to receive infrared signal just is equivalent to button and lifts; Button principle and common key-press that it is essential do not have too big difference; The media of different is button has changed, and common button operation is a mechanical action, and the button operation of the photosensitive formula button that is used for calorimeter that the embodiment of the invention provides is an infrared signal.
The photosensitive formula button that is used for calorimeter that the embodiment of the invention provides comprises infrared light-inductive pipe and infrarede emitting diode, can be applied in the most applied environment; And owing to adopt the cured layer enclosed package, this photosensitive formula button that is used for calorimeter can be applied in the device and the environment of specific (special) requirements such as water proof and dust proof.
