Abstract
The utility model relates to a handheld light measuring probe device, which is applied to brightness collection of a liquid crystal display in the medical field. The device body is in a cylindrical structure, the lateral surface is a front casing, a spotlight piece is fixedly installed on the upper bottom face and arranged in the front casing, a light sensing circuit is further fixed in the front casing, and the lower bottom face is a back cover packing the spotlight piece and the light sensing circuit inside the cylindrical structure. A small hole is arranged between the back cover and the front casing. The light sensing circuit comprises a microprocessing unit used for receiving and transmitting orders and finishing data communication tasks and a light sensing unit used for collection brightness. The light sensing unit integrates a light sensing chip and a built-in filtering piece, a photoelectric diode and an analog-to-digital (A/D) conversion circuit. A universal serial bus (USB) wire is led out from the light sensing circuit and penetrates through the small hole between the back cover and the front casing. The handheld light measuring probe device has the advantages of being simple in design, convenient to use and accurate in brightness test result.
Description
Technical field
The utility model relates to a kind of hand-held photometry probe apparatus, is applied to the brightness collection of LCD in the medical field.
Background technology
At present, be applied to the brightness that the light measurer of medical field mainly is used for gathering medical LCD.The key component of device is built-in photosensitive unit, is made up of optical filter, photodiode and A/D change-over circuit.The precision of photosensitive unit is determining the precision that brightness is gathered.Optical filter, photodiode and A/D circuit are three independently unit in the part light measurer, have increased the complicacy of circuit design like this, have also introduced bigger identification error.Some light measurer is high-precision photosensitive unit owing to what adopt, and its expensive is difficult to ordinary consumer and receives.Simultaneously, light measurer does not have complete software systems to do support, and is inconvenient to carry.
The utility model content
The purpose of the utility model is to the problems referred to above that exist in the prior art, and a kind of simplicity of design, easy to use, test brightness result's the photometry of hand-held accurately probe apparatus is provided.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: hand-held photometry probe apparatus is characterized in that main body is a cylindrical structural; Side surface is a fore shell; Upper bottom surface fixedly is equipped with concentration piece, and concentration piece is positioned at fore shell, also is fixed with photosensitive circuit in the fore shell; Bottom surface is a bonnet, and bonnet is encapsulated in cylindrical structural inside with concentration piece and photosensitive circuit.
Be provided with an aperture between said bonnet and the fore shell.
Said photosensitive circuit comprises to be accomplished the microprocessing unit that receives, sends order and data communications task and gathers the photosensitive unit of brightness.
The integrated sensitive chip of said photosensitive unit, built-in optical filter, photodiode and A/D change-over circuit.
Said photosensitive circuit is drawn the USB line, passes the aperture between bonnet and fore shell.
The beneficial effect of the utility model is embodied in:
1, the luminance index of test medical LCD, test brightness result's is accurate, and the data processing algorithm that adopts in the software systems guarantees luminance accuracy.
2, the exterior design of hand-held facilitates for testing and carrying.
