Illumination light source and lighting apparatus
View Patent ↗An LED unit which serves as an illumination light source includes: a light-emitting element; a circuit board provided in a drive circuit which drives the light-emitting element; a lead wire electrically connecting the light-emitting element and the drive circuit; and a case including a first opening which is an elongated opening into which the lead wire is inserted. The circuit board includes a second opening which is an elongated opening into which the lead wire is inserted, and the first opening and the second opening are disposed so that a straight line extending in a lengthwise direction of the first opening and a straight line extending in a lengthwise direction of the second opening three-dimensionally cross each other.
1. An illumination light source comprising:
a light-emitting element;
a circuit board provided in a drive circuit which drives the light-emitting element;
a lead wire electrically connecting the light-emitting element and the drive circuit; and
a case including a first opening which is an elongated opening into which the lead wire is inserted,
wherein the circuit board includes a second opening which is an elongated opening into which the lead wire is inserted, and
the first opening and the second opening are disposed so that a straight line extending in a lengthwise direction of the first opening and a straight line extending in a lengthwise direction of the second opening three-dimensionally cross each other.
2. The illumination light source according to claim 1 ,
wherein the case further includes a third opening which is an opening connected to the first opening, for guiding the lead wire from outside to the first opening.
3. The illumination light source according to claim 2 ,
wherein the third opening is disposed at a position that does not overlap with the second opening, when seen from a plan view direction of the circuit board.
4. The illumination light source according to claim 2 ,
wherein the first opening and the third opening make up an L-shaped cut-out formed in the case.
5. The illumination light source according to claim 1 ,
wherein the second opening is a linear cut-out formed in the circuit board.
6. The illumination light source according to claim 1 ,
wherein the circuit board further includes a fourth opening which is an opening connected to the second opening, for guiding the lead wire from outside to the second opening.
7. A lighting apparatus comprising:
the illumination light source according to claim 1 ; and
lighting equipment to which the illumination light source is attached,
wherein the lighting equipment includes:
a main body configured to cover the illumination light source; and
a socket attached to the main body, for supplying power to the illumination light source.
8. The illumination light source according to claim 1 , wherein the circuit board is accommodated within the case.
9. The illumination light source according to claim 1 , wherein the lengthwise direction of the first opening is oriented parallel to a planar surface of the case and a lengthwise direction of the second opening is oriented parallel to a planar surface of the circuit board.
