20130182425 | LAMP AND LIGHTING APPARATUS - A lamp according to the present invention includes: a line portion which blocks a part of light proceeding from a light emitting unit in a direction perpendicular to a tube axis direction; and a raised portion which blocks the light proceeding from the light emitting unit in the direction perpendicular to the tube axis direction that is not blocked by the line portion. The raised portion has an end portion having a linear shape in the tube axis direction, the end portion being an end portion of a section of the raised portion that blocks light. | 07-18-2013 |
20140177240 | LIGHTING DEVICE AND LIGHT-EMITTING MODULE - A lighting device pertaining to one aspect of the present invention includes a mount, a light-emitting module, and a substrate holder. The light-emitting module is mounted on a main surface of the mount, and the substrate holder covers a portion of the light-emitting module and is connected with the mount. The light-emitting module includes a substrate, a plurality of light-emitting elements, a sealant and a padding. The padding is provided on a first main surface of the substrate. The light-emitting module is mounted on the main surface of the mount such that a second main surface of the substrate comes into contact with the main surface of the mount, and the light-emitting module is fixed to the mount by pressure applied from the substrate holder via the padding brought into contact with the substrate holder. The padding is made of a same material as the sealant. | 06-26-2014 |
20140204560 | ILLUMINATION LIGHT SOURCE AND LIGHTING APPARATUS - An LED unit which serves as an illumination light source includes: a mounting board on which a light-emitting element, which emits light frontward, is provided; a support disposed behind the mounting board; and a case disposed so that the mounting board is sandwiched in a longitudinal direction by the case and the support. The case includes a restricting portion which restricts sideward movement of the mounting board. | 07-24-2014 |
20140204561 | ILLUMINATION LIGHT SOURCE AND LIGHTING APPARATUS - 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. | 07-24-2014 |
20140204562 | ILLUMINATION LIGHT SOURCE AND LIGHTING APPARATUS - An LED unit which serves as an illumination light source that is attached to lighting equipment includes: a light-emitting element; a circuit board provided in a drive circuit which drives the light-emitting element; a case inside of which the circuit board is disposed; and a connecting component at least a portion of which is disposed inside the case, for electrically connecting the lighting equipment and the drive circuit. The case includes a positioning portion which determines a position of the circuit board, and the circuit board includes an opening into which the connecting component is inserted, and which determines the position of the circuit board by way of the rim of the opening abutting the positioning portion. | 07-24-2014 |
20140204594 | ILLUMINATION LIGHT SOURCE AND LIGHTING APPARATUS - An illumination light source which attaches to a lighting fixture by being rotated in a predetermined rotational direction R, the illumination light source including: a light-emitting unit (LED module), a case which includes a first opening and houses the light-emitting unit; and a translucent cover provided over the first opening, wherein the translucent cover includes a plurality of projecting portions provided at predetermined intervals in the rotational direction R, and the plurality of projecting portions each include a plurality of projections provided at a predetermined distance from each other in the rotational direction R and including a flat surface facing a direction opposite the rotational direction R. | 07-24-2014 |
20150085495 | LAMP AND LIGHTING APPARATUS - A lamp including: a reflecting mirror; a case inside which the reflecting mirror is entirely or partially disposed, and which has an opening formed therein; and a light-transmissive cover covering the opening of the case. The reflecting mirror includes a case-side reflecting mirror connecting part for connecting with the case, and the case includes a mirror-side case connecting part which connects with the case-side reflecting mirror connecting part. The case further includes a cover-side case connecting part for connecting with the light-transmissive cover, and the light-transmissive cover includes a case-side cover connecting part which connects with the cover-side case connecting part. The light-transmissive cover further includes a mirror-side cover connecting part for connecting with the reflecting mirror, and the reflecting mirror further includes a cover-side reflecting mirror connecting part which connects with the mirror-side cover connecting part. | 03-26-2015 |
