Abstract:
1. A linear light source comprising: a square rod-shaped wiring board having a component side; a plurality of light emitting elements which are arranged on the component side of the wiring board at certain intervals along the longitudinal direction of the wiring board and die-bonded thereto; and a plurality of reflectors which are arranged at both sides of each of the light emitting elements on the component side of the wiring board such that the reflectors and the light emitting elements are arranged alternately; wherein adjacent two reflectors have opposing surfaces facing each other with the light emitting element sandwiched therebetween, the opposing surfaces of the reflectors are inclined such that the distance between the opposing surfaces increases in the direction of light emitted out of the light emitting element, and open-ended channels are formed, each of which is defined by the component side of the wiring board and the adjacent two reflectors arranged at both sides of each of the light emitting elements.
