VCC's LPX Series lightpipes are designed to provide a method of transmitting the light from a circuit board surface mounted LED to a display panel. In addition, they are capable of blending the colours of new multicolour LEDs. They are available with three display lens shapes and produce up to 160° viewing angle.
Recent technological advances by the LED manufacturers of surface mount LEDs include multichips, increased brightness and lower power usage. Due to their new super small package size, designed for pick-and-place assembly equipment, these LEDs are not suitable for front panel displays.
Current methods of transmitting the light of a surface mount LED on a PCB to a front panel are less than acceptable aesthetically and physically. Lightpipes are typically attached to the PCB by moulded plastic pegs. These are quite fragile and, being attached to the PCB prior to final chassis assembly, care must be exercised to prevent damage. Alignment to the panel cutout during final assembly also causes difficulties.
The LPX Series 4 mm lightpipes are designed for use with both vertical and horizontal surface mount LEDs while their physical attachment is made directly to the display panel. Combining the physical attachment advantage with the fact that the lightpipe is available in 81 lengths, the designer has much freedom in the positioning of the circuit board within the chassis. These features allow for easy board insertion in final assembly or removal for inspection and repair.
Further, the display lens is designed as low profile with fresnel rings in three different styles; round, square and rectangular. The lens will disperse the light up to 160°. The light receiving end of the lightpipe has a concave surface designed to be positioned in front of the horizontal surface-mounted LED or directly over the top of the vertical surface-mounted LED.
The lightpipes are tubular in shape, moulded from an optical grade of acrylic plastic for clarity with highly polished surfaces for optimum light refraction and transmission. The LPX is secured directly to the display panel by means of a retaining clip or grommet.
