Abstract

A plurality of LEDs are provided to an outer edge side of a center position of one main surface of an LED substrate main body in a deviated manner respectively. The wiring part including the connector receiving part and the wiring hole are provided at a position that overlaps the center position of the one main surface side of the LED substrate main body. Since the power feeding part is inserted into the wiring hole, the connection part and the connector receiving part can be easily connected and therefore it becomes possible to ensure ease in assembly. Since the connector receiving part is kept away from each of the LEDs with substantially equal distance so that emitted light is hardly blocked, decrease in uniformity of light distribution can be suppressed.

Claims

1. A lamp including:

an element substrate comprising;

an element substrate main body, a plurality of light emitting elements provided at positions deviating to an outer edge side from a center position of one main surface of the element substrate main body, and

a wiring part having a connection receiving part electrically connected to the light emitting elements and a wiring hole which is formed adjacent to the connection receiving part and is penetrating via the element substrate main body which is provided in a manner that at least a part thereof overlaps the center position of the one main surface side of the element substrate main body;

a radiator having one edge side which is attached to the other main surface side of the element substrate main body of the element substrate while being in close contact with the other main surface side;

a cap attached to the other edge side of the radiator; and

a lighting device stored between the radiator and the cap which includes a power feeder and a connection part connected to a distal end of the power feeder to be connected to the connection receiving part and a power feeding part which can be inserted into the wiring hole for controlling lighting of the light emitting element.

2. The lamp according to claim 1, wherein

the radiator includes an insertion hole where the power feeder of the lighting device can be inserted at a position that corresponds to the wiring hole of the element substrate in a condition where the element substrate main body of the element substrate is attached to one edge side of the radiator.

3. The lamp according to claim 1, including a storage case which insulates the radiator and the cap, the storage case being is provided between the radiator and the cap, for storing the lighting device.

4. The lamp according to claim 3, wherein

the radiator includes the one edge part having a support part where the element substrate is provided and another edge part having a storage concave portion where the lighting device is provided,

the storage case has an aperture that communicates with the storage concave portion and is provided so as to intervene between the lighting device and the storage concave portion of the radiator, and

the radiator includes a thermal conductive member which is provided to thermally connect the lighting device and surface of the storage concave portion of the radiator via the aperture of the storage case.

5. The lamp according to claim 4, wherein

the lighting device is provided in the storage case approximately along the center axis direction of the radiator,

the storage concave portion has a protrusion protruding toward the lighting device in an integrated manner, and

the thermal conductive member connects the lighting device and the protrusion via an aperture.

6. Lighting equipment including:

an equipment main body having a socket; and

the lamp according to claim 1 with a cap which is mounted on the socket.
