Abstract
It is an object of the present invention to provide a light source unit enabling cost reduction. A light source unit of the present invention includes a plurality of LEDs 16, and an elongated LED board 17 having a plurality of arranging portions 18 on which each LED 16 is arranged, and a plurality of connecting portions 19 connecting the adjacent arranging portions 18. Each connecting portion 19 has a width smaller than a width of each arranging portion 18 in a short direction of the LED board 17.
Claims13
A light source unit comprising:
- a plurality of light sources;
- and
- an elongated board including a plurality of first portions and a second portion, each of the plurality of first portions including at least one of the plurality of light sources thereon and the second portion is provided between two adjacent ones of the plurality of first portions, wherein
- the elongated board has an outer shape including first widths in a latitudinal direction of the board crossing the plurality of first portions as seen in a plan view and a second width in the latitudinal direction of the board crossing the second portion as seen in a plan view, the second width being smaller than each of the first widths;
- and
- the second portion has a length greater than a length of each of the plurality of first portions in a longitudinal direction of the board.
A light source unit comprising:
- a plurality of light sources;
- and
- an elongated board including a plurality of first portions and a second portion, each of the plurality of first portions including at least one of the plurality of light sources thereon and the second portion is provided between two adjacent ones of the plurality of first portions, wherein
- the elongated board has an outer shape including first widths in a latitudinal direction of the board crossing the plurality of first portions as seen in a plan view and a second width in the latitudinal direction of the board crossing the second portion as seen in a plan view, the second width being smaller than each of the first widths;
- and
- the board includes an outer shape such that, when one board is rotated by 180 degrees, each of the plurality of first portions of another board that is not rotated is fitted between the plurality of first portions of the rotated one board.
A method of manufacturing an elongated board used for a light source unit, comprising:
- dividing one rectangular board base material to form a plurality of elongated boards used for a light source unit, each of the plurality of elongated boards including a plurality of first portions and a second portion, each of the plurality of first portions includes a light source thereon and the second portion is provided between two adjacent ones of the plurality of first portions;
- wherein
- the second portion has a width smaller than a width of each of the plurality of first portions in a latitudinal direction of the board as seen in a plan view, and
- the dividing step including dividing the board base material into at least a first board and a second board such that each of the plurality of first portions of the second board adjacent to the first board is located between two adjacent ones of the plurality of first portions of the first board.
