Semiconductor light emitting unit, method for manufacturing same and linear light source

摘要

A semiconductor light emitting unit is provided which comprises: a support 1 formed with longitudinal side walls 15 disposed opposite to each other for forming a pair of light reflective surfaces 9, and a bottom wall 16 connected to longitudinal side walls 15 for forming a mount surface 3 a between light reflective surfaces 9 to form a channel 3 by longitudinal side walls 15 and bottom wall 16 above mount surface 3 a. Formed at either end of channel 3 in the longitudinal direction of support 1 is a vertical opening 18 which serves to directly communicate channels 3 of adjacent light emitting units when plural semiconductor light emitting units are lengthwise arranged, so that there is no lateral side wall 15 obstructing path of light radiated from LED chips 2 toward outside to thereby irradiate uniform light to outside along the longitudinal direction of linear light source.
