It is constrained on degree to popularize on a large scale.It is relatively more in middle-and-high-ranking hospital, and advanced Non-Destructive Testing unit use at present.
The advantages of LED viewboxs are relative to common viewbox；
Using state-of-the-art LED solid state illumination technologies and advanced back light source technique；Its light intensity distributions uniformly, no dark space, nothing
Stroboscopic, colour temperature are stable, make screen more bright, soft.LED viewboxs are greatly improved medical image photo observation device
Quality, to ensureing that medical imaging diagnosis quality has important value.
1st, LED viewboxs use the LED solid-state illumination light sources of state-of-the-art technology, and operating voltage of the light source is the safety of 24 volts of direct current
Voltage, and security, stability, reliability are all improved.
2nd, evenly, multi-joint film illuminator can reach more than 80% without any dark space, uniform intensity degree, other viewboxs
Uniform intensity degree only has 70%.
3rd, thinner, LED viewbox thickness is smaller than 23mm.CCFL liquid crystal viewboxs thickness is 25 mm.
4th, brighter, maximum brightness can reach more than 4000cd/m2, traditional fluorescent lamp or CCFL liquid crystal viewbox highests
Brightness only 1200cd/m2 or so.LED viewboxs greatly improve medical imaging diagnosis quality.
5th, colour temperature is more stable, avoids traditional fluorescent lamp or CCFL and sees the easy color of LCD panel lamp fluorescent tube and declines caused jaundice
Phenomenon.
6th, the life-span is longer, and LED light source service life is 50,000 hours, about the three of CCFL liquid crystal viewbox times, common fluorescent lamp
Five to ten times of pipe viewbox.
7th, it is more environmentally friendly, there is the environmental protection characteristic of mercury-free.
8th, national standard is complied fully with《Medical image photo general technical specifications》, key index can be higher than the standard.And
The luminance index of fluorescent lamp or CCFL liquid crystal viewboxs is unable to reach standard requirement.
9th, brightness stability, no stroboscopic, greatly reduces visual fatigue.
10th, without starting preheating, and CCFL liquid crystal viewbox and common viewbox need thermal starting.
11st, LED medical piece-looking lamps are compared with tradition with viewbox, due to using intellectual technology, adding many new work(
Can, such as：Inserted sheet senses（Insert i.e. bright）, subregion lights, button light modulation, brightness digital-scroll technique, brightness memory, and timing shutdown is special
It is not hand-operated and automatic function, only user does not provide conveniently, and energy-saving and environmental protection, the life-span that substantially prolongs product.
Viewbox is common Medical Devices, and in general viewbox is the viewbox of lamp box type at present, and it is more heavy, no
Easily mobile, light source is poor, damages the eyesight of doctor, and brightness is unadjustable, can not adjust what doctors wanted as needed
Brightness.
