Abstract
The utility model relates to a device for testing the flash duration of an electronic flash lamp, which is characterized by comprising a master control computer chip provided with a counter module and an operation module, a photosensitive receiving module used for transmitting received signals to the counter module of the master control computer chip via a drive module, and a display module. The operation result of the operation module of the master control computer chip is transmitted to the display module for being displayed via a display drive module. The device is simple in structure. Due to the adoption of the device, the flash duration of the electronic flash lamp can be accurately and visually tested.
Description
Technical field
The utility model relates to a kind of X-flash flash duration proving installation.
Background technology
The problem that the flash duration person of being to use of flashlamp and the producer are concerned about.In photographic process, because the difference of camera shutter pattern has different requirements to flash duration, as the flash duration of curtain synchronous mode requirement before arranging is short, then the flash duration that then requires of curtain synchronous mode is longer, thus the effect that the high-speed shutter that reaches slit scanning also can synchronization flash.Simultaneously, in process of production, the flash unit of different purposes has different requirements to flash duration too.But, also there is not at present such device that can accurately calculate flash duration, and the method for tradition measuring and calculating flash duration is to draw the external flashing equipment that dodges under the camera shutter gear by arranging, thereby blur the flash duration of extrapolating external flashing equipment by aperture time, but can't obtain a test data accurate and visually.
The utility model content
In order to address this problem, the utility model provides a device that is specifically designed to the flash duration test, can test out the flash duration of flash unit accurately, intuitively.
The utility model adopts following scheme to realize: a kind of X-flash flash duration proving installation is characterized in that comprising:
One is provided with the master control computer chip of counter module and computing module;
One photosensitive receiver module, this photosensitive receiver module are given the signal that receives through a driver module counter module of described master control computer chip; And
One display module, the computing module of described master control computer chip are given described display module with operation result by driver module and are shown.
In the utility model one embodiment, described master control computer chip also is connected with a reset key.
In the utility model one embodiment, described display module is the flash duration display module, and this flash duration display module is the image curve display screen that digital display screen maybe can read time data.
The utility model is simple in structure, can accurately test the time that the flashlamp flash of light continues by counter module and the computing module of master control computer chip.
Description of drawings
Fig. 1 is the utility model circuit catenation principle block diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, present embodiment provides a kind of X-flash flash duration proving installation, it is characterized in that comprising:
One is provided with the master control computer chip 1 of counter module 2 and computing module 3;
One photosensitive receiver module 4, this photosensitive receiver module are given the signal that receives through a driver module 5 counter module of described master control computer chip; And
One display module 6, the computing module of described master control computer chip are given described display module with operation result by driver module 7 and are shown.
Principle of work of the present utility model is to pick up " counter module " that the flashing signal of photoflash delivers to flashing signal in the master control computer chip by " driving circuit " by " photosensitive receiver module " to calculate, " counter module " can calculate beginning to end of flash duration, the signal that becomes suitable " display module " to show by " computing module " computing is delivered to " driver module " again, show the duration of glistening by " driver module " driving " display module ", flash duration can be retained in for a long time to be convenient in the display watch.In addition, in the present embodiment, described master control computer chip also is connected with a reset key, should " reset key " give the processing of computer main control chip with reset signal, resets.
Initialization " display module " initialization value is 0 in the time of the start of this device.When flashlamp flash of light finishes, horse back demonstrates the numerical value of flash duration device on, when pressing reset key, circuit reset at once " display module " be shown as initialization value, flash duration numerical value is next time picked up in preparation.
The flash duration display module can be digital display screen or the image curve display screen that can read time data.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
