Whatis LGF Dome Array and How does it work ?
LGF metal dome array , which full name is Light Guide Film , it is a new design . which used to replace LED in function , in comparsion with LED , lighting Uniformity; When we add a LGF on current normal double layer or EMI dome array, it becomes a LGF dome array. It can achieve great result of light distribution.see from the design , the light under keypad is coming from the LED on PCB motherboard. We need to put about 8-10 pieces LED on each board, but if the design changed to use LGF, then we can save several LED, as well as SMT fee.
What is the LGF DESIGN PRINCIPLE& What is the Advantage ?
LGF, at least one surface out of front and rear surfaces of the light guide film is formed with a pattern such that density increases as distanced from a light source to allow light to be uniformly supplied to the keypad, or is concentratively formed with a pattern at a particular region of the light guide film to allow the light to be concentratively supplied to a particular region of the keypad.
