Description
Technical field
The utility model relates to the finder of medical image photo, specifically a kind of observation lamp of medical film.
Background technology
The medical film observation device is the equipment that the medical personnel of hospital is used to observe the medical image photo, old-fashioned medical viewbox is as light-emitting component with fluorescent lamp, have high pressure, high energy consumption, stroboscopic, light and shade inequality, easily wear out, lack service life, fluorescent tube destruction can be caused mercury pollution.
Used cold utmost point pipe of CCFL and LGP to constitute the light source of viewbox in recent years, compare original fluorescent lamp very big progress has been arranged, but the industry standard that also exists brightness not reach country requires, exists altitude temperature difference effect, and low-temperature condition is difficult for defectives such as startup and the mercurous not environmental protection of element down.
At present, also there is producer to adopt LED to substitute the CCFL fluorescent tube, but adopted LGP, the more requirement that does not still reach industry standard of the loss of light source.
The utility model content
The technical problem that the utility model solved is to provide a kind of dot matrix direct-injection type LED highlighted viewbox, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
The highlighted viewbox of dot matrix direct-injection type LED comprises casing, dot matrix direct-injection type led board, single-chip microcomputer adjusting control circuit, wide voltage high frequency switch power, and described dot matrix direct-injection type led board and single-chip microcomputer adjusting control circuit are arranged in the case.
In the utility model, described casing is made up of mold, aluminium section bar, Ya Keli plate and aluminium sheet.
In the utility model, described dot matrix direct-injection type led board is made up of the SMD white light LEDs of a hundreds of high brightness and white sensitization pcb board and constant current control chip.
In the utility model, described single-chip microcomputer adjusting control circuit is made up of single-chip microcomputer and peripheral circuit, touch-switch, inductive switch, digital display tube or light emitting diode.Wherein the single-chip microcomputer dimming mode is the PWM light modulation, and charactron is used for display brightness levels, and inductive switch is that Photoelectric infrared switch is used for responding to film.
In the utility model, described wide voltage high frequency switch power is that input voltage is AC100V-250V/50-60Hz.
Beneficial effect: the utility model brightness is even, frequency is high, brightness is high, energy consumption is low:
1, adopted dot matrix direct-injection type led board, the loss minimum of light so can utilize luminous energy to greatest extent, also can provide the brightness of superelevation under the less situation of energy consumption.Spacing between the plurality of LEDs equates, adds repeatedly reflection between the Ya Keli plate of white and the white sensitization pcb board, the light that shows is more even, meets the medical industry prescribed by standard fully.Led light source does not have the described shortcoming in front, and this just provides cost savings to the client, can better help the doctor to observe film, reduces mistaken diagnosis and fails to pinpoint a disease in diagnosis.
2, adopt the single-chip microcomputer adjusting control circuit, avoided the fault of the easy loose contact of potentiometer dimming mode, adopt Photoelectric infrared switch to respond to film, have sheet to light, no sheet extinguishes, and can better save electric energy.
3, adopt wide voltage high frequency switch power, can better adapt to the voltage of each department.
Description of drawings
Fig. 1 is an electric theory diagram of the present utility model;
Fig. 2 is the utility model circuit diagram;
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the highlighted viewbox of Fig. 1 dot matrix direct-injection type LED, comprise wide voltage high frequency switch power 1, single-chip microcomputer adjusting control circuit 2, dot matrix direct-injection type led board 3.
The highlighted viewbox of dot matrix direct-injection type LED, the external power of AC100-250V converts direct current to by wide voltage high frequency switch power 1, be divided into two-way, one road electricity enters dot matrix direct-injection type led board 3, one road electricity enters single-chip microcomputer adjusting control circuit 2, single-chip microcomputer adjusting control circuit 2 connects dot matrix direct-injection type led board 3, can regulate the brightness of dot matrix direct-injection type led board 3.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
