LPCM Low Profile, Panel Flush Light Pipes VCC LPCM Series Low Profile, Panel Flush Light Pipes are the first light pipes to be offered by VCC which can be directly mounted to the board. These light pipes transmit from the SMD LED right to the front of a panel. The LPCM series features a low profile with a panel flush design that blends in until light is emitted. The light pipes are available in standard lengths of .300' to 1.20' and are made of an optical grade acrylic for maximum light transmission. These light pipes allow for easy panel removal, offer efficient production assembly, and will mate to any PCB using SMD 4 (sold separately).
