Product:lightguide for medical equipment 

Types and features:
Cold cathode fluorescent lamp (CCFL) backlight: It was once the mainstream technology for the backlight of medical equipment display screens. It is usually powered by a DC-AC inverter and can convert direct current into alternating current to light up the lamp. Its advantages are that it can provide bright white light, can provide good backlight for LCD, and the temperature will not be much higher than the ambient temperature, which is friendly to LCD panels. And the light is relatively uniform, suitable for equipment that requires a stable light source, such as X-ray machines, endoscopes, etc. However, CCFL backlight has disadvantages such as high power consumption, containing mercury elements that are not environmentally friendly, and requiring high-voltage inverters.
Light-emitting diode (LED) backlight: It is a backlight technology that is gradually becoming popular. LED backlights are generally driven by a constant current source and do not require a high-voltage inverter. It has the advantages of high brightness, low energy consumption, long life, good shock resistance, etc. It can also provide a wider color gamut, does not contain mercury, and is more environmentally friendly. In addition, the dimming range of LED backlight is wide, up to 20000:1, which can meet different environments and usage requirements. But its disadvantage is that the cost is relatively high, and a good heat dissipation design is required to ensure performance.

Technical parameters:
Brightness: usually expressed in cd/m². Different medical devices have different requirements for backlight brightness. For example, the brightness of medical film viewing lamps can reach more than 4000cd/m² to clearly display X-ray image details. Generally, the brightness of LED backlights is between 300cd/m²-4500cd/m², or even higher.
Color temperature: The unit is K (Kelvin). The color temperature of CCFL backlights is usually above 10000K, which is suitable for viewing X-RAY films. The color temperature of LED backlights can be customized according to needs. Common ones are above 6500K, and there are also products that can reach 10000K. High color temperature can make the image clearer and sharper.
Working voltage and current: There are differences in backlights of different types and sizes. For example, the operating voltage of some small LED backlight sources may be 2.9V-3.1V, and the operating current is 15-20mA. The driving voltage of CCFL backlight sources needs to be converted from 5-48Vdc DC voltage to AC high voltage through an inverter.
Thickness: To meet the demand for thinner and lighter medical equipment, the thickness of backlight sources is constantly decreasing. For example, the widest part of Lumex's Quantum Brite flexible LED backlight source is only 0.6mm, which is 88% thinner than the standard 5mm thick LED backlight source.

Size and shape: The size can be customized according to the needs of medical equipment display screens. Common ones include 4.8-inch backlights for small handheld devices and more than 20-inch backlights for large displays. In terms of shape, in addition to conventional rectangles, there are also round and special shapes. For example, flexible LED backlights can be designed into various shapes according to the shape of the equipment, which are suitable for indicator lights, logo decorations and display components of various equipment such as medical radiation equipment, monitors, defibrillators, and infusion pumps.
Luminous color: mainly white, blue, green, red, etc. White light is more commonly used for display backlight to provide clear visual effects; blue light and green light are often used for indicator lights, and different colors can represent different working states or warning information. For example, the EL backlight of Canhui Optoelectronics has a variety of colors to choose from, such as blue-green light, red, yellow, and white.

Application scenarios:
Intensive Care Unit (ICU) equipment: The ambient light in the ICU is usually dim to take care of the patient's rest. Backlights are used in monitors, ventilators and other equipment, allowing medical staff to clearly see the equipment parameters and operation interface in a dim environment to ensure timely and accurate operation.
Diagnostic equipment: such as ultrasound machines, clear interface display is essential for accurate diagnosis. Backlight makes screen images and operation buttons more eye-catching, allowing doctors to quickly obtain information and improve diagnostic efficiency and accuracy.

Operating room equipment: During surgery, doctors need to focus on the surgical area, and the equipment backlight needs to provide soft and clear light without glare to avoid affecting the doctor's vision. For example, the backlight of the surgical lamp can help doctors clearly view the control panel and adjust the lighting parameters.
Material and safety: The backlight shell and internal components are usually made of environmentally friendly and non-toxic materials that meet relevant standards of the medical industry. For example, LED medical film viewing lamps use solid light, non-glass tube shells, no need for inflation, not easy to break, strong shock resistance, and no mercury in the light source. Waste can be recycled, which is conducive to environmental protection. In addition, some backlight sources also use antibacterial materials to facilitate cleaning and disinfection, prevent cross infection, and meet the hygiene requirements of the medical environment.
