Light Guide Film (LGF)
Light Guide Film (LGF) is a thin film backlighting technology that will direct light produced by side-firing or right-angle LEDs across the area that needs to be backlit.
The advantage of LGF is that the film can be fabricated into almost any shape, providing consistent backlighting across one or more areas within the switch.
Multiple LGF films can be used within one application to provide discrete backlighting to different graphic features.
Different colored LEDs can be used to achieve unique lighting effects or white LEDs can be used to light different printed graphics on the overlay.
Although Light Guide Film can be more expensive than other backlighting technologies (below), it has several advantages:
1.The LGF is extremely thin so it can be incorporated into membrane switches that can’t exceed a certain thickness (i.e. small, lighter devices)
2.LGF has limited impact on the tactile feel of buttons.
3.LGF can provide even backlighting across large and small areas, including applications where the light remains on while the switch is powered.
Electroluminescent (EL) Lighting EL
EL lamps contain phosphors, which convert electrical energy directly into light energy. The high efficiency of this conversion minimizes power consumption and losses due to heat or IR emissions. EL backlighting devices consequently consume relatively little power under normal operation. They are best suited for low and no light applications where the backlight is not always on, because the phosphors tend to decay with extended use at high voltages and frequencies. The useful life of an EL lamp will vary depending on the quality of the phosphors and how hard the lamp is being driven.
Some additional features and design considerations for EL lamps are:
EL lamps consume very little power
Provides uniform, balanced backlighting of the entire membrane switch area
Requires a DC to AC inverter to operate
Thin profile and durability make it suitable for most membrane switch constructions
