Secondly, the light from the LED luminescence diode can be refracted equally by the peach-shaped diffusion covers, thereby becoming more softness. Thirdly, the LED luminous source is the solid luminous source, having no pollution to the environment. Fourthly, the local or holistic light intensity is adjustable, as well as the color temperature. Fifthly, the thickness of the box is reduced for taking expediently.
Description
Technical field:
The utility model relates to a kind of medical X-ray film film viewing light box and rollfilm egative film film viewing light box, belongs to film viewing light box and makes the field.
Background technology:
Granted publication CN2572425Y, title " medical X-ray film film viewing light box ", this lamp box comprises casing, translucent material sheet, tubular light source, also be provided with the light guide plate made from pmma material, the light guide plate that pmma material is made is installed on the casing, translucent material sheet is positioned at the light guide plate front and constitutes the film viewing screen curtain, tubular light source is parallel to be installed in the casing of light guide plate side symmetrically, and the back of light guide plate is provided with opaque reflective structure.Tubular light source can be daylight lamp or cold-cathode fluorescence lamp.Its weak point: the one, no matter be to adopt daylight lamp, still adopt cold-cathode fluorescence lamp, not only volume is big, energy consumption is high, and the light that is produced is the strip light distributed, to such an extent as to illumination is difficult for accomplishing that evenly this can directly influence sight sheet effect; The 2nd, the required operating voltage of daylight lamp or cold-cathode fluorescence lamp is a high voltage, and fluorescent tube is to vacuumize making with glass tube, and fluorescent tube is very frangible, so inconvenience is used for open-air the use, and inconvenient army uses and move use in open-air battlefield; The 3rd, the light intensity of daylight lamp or cold-cathode fluorescence lamp normally inconvenience is regulated, and so just can not be fit to the careful observation to the different densities film.The structure of this film film viewing light box be present nearly all film film viewing light box the structure that generally adopts.
Summary of the invention:
Purpose of design: the weak point of avoiding background technology to exist, design a kind of LED film film viewing light box that replaces daylight lamp and cold-cathode fluorescent lamp source with the LED light emitting source.
Design proposal: in order to realize above-mentioned purpose of design.On structural design, on the basis of existing film viewing light box (medical X-ray film film viewing light box, rollfilm egative film film viewing light box), daylight lamp illuminating source in the film viewing light box or cold-cathode fluorescence lamp illuminating source are replaced with the LED light emitting source, and get and remove requisite light guide plate, that is to say, with a plurality of white light LEDs light emitting sources organize three-color LED (red, green, blueness) more or four look LED (red, amber, green, blueness) replacement background technology in daylight lamp or cold-cathode fluorescence lamp light emitting source.The positive and negative electrode of LED illumination light source unit group can be divided into groups to connect or whole the connection as required.The grouping connection is meant: a plurality of LED illumination light source unit are divided into some groups, and every group by connecing power control terminal after the polarity connection; The whole connection is meant: all LED illumination light source unit connect power control terminal after connecting by polarity.No matter be to divide into groups to connect, still whole the connection, its power supply is a low-voltage dc power supply, and controls the power of LED light emitting source by control circuit.Its technical scheme: it comprises casing (1), light-passing board (4) is positioned on casing (1) mouth, bottom in the casing (1) and be equipped with reflection horizon (2) all around, a plurality of LED light emitting diodes (3) are distributed on the bottom (2), and the LED with the light distribution of bat wing is gone up or directly adopted to the lens cap of bat wing light distribution at LED light emitting diode (3).
The utility model is compared with background technology: the one, and the LED light emitting source is a cold light source, light but not heats can not produce heat in the front of lamp box, therefore can not exert an adverse impact to observed film rete, the efficiency height, energy-conservation; The 2nd, be positioned at light that the lens of the bat wing light distribution on the LED light emitting diode can send the LED light emitting diode to around disperse, and coming back reflective all around and on the reflecting surface of bottom surface, make light more evenly soft, can reduce light guide plate, not only can reduce cost and weight, also improve light efficiency; The 3rd, because the LED light emitting source is free of contamination solid luminescence source, therefore there is not pollution to environment, and cracky not, sturdy and durable; The 4th, because the LED light emitting source can adopt DC low-voltage to drive, be particularly suitable for the use that the field is medical, the battlefield is medical or move use; The 5th, the mixed light ratio of luminous intensity that can be by regulating the LED modules with different colors in three-color LED (red, green, blueness) unit group or four look LED (red, amber, green, blueness) the unit group can produce the light of different-colour, the specific (special) requirements and the adaptability of different ethnic group eyes to color of satisfied sight sheet; The 6th, but because LED light emitting source direct drive, therefore can adopt adjustable constant-flow circuit or width modulation (PWM) technology to realize easily or the joint light modulation is arranged from 0～100% stepless dimming, and adjustable local light intensity or whole light intensity, satisfied careful observation to different film densities; The 7th, reduced to see the thickness of sheet casing widely, weight reduction is convenient for carrying; The 8th, the life-span is long, can reach more than 100,000 hours in theory, is daylight lamp illuminating source or cold-cathode fluorescence lamp tens of times.
