20090003010 | VEHICLE LAMP - A vehicle lamp includes a convex lens and a light emitting device. Light directly reaching a rear surface of the convex lens from the light emitting device is deflected through the convex lens to form a light distribution pattern having a horizontal cutoff line and an oblique cutoff line. The light emitting device includes a light emitting chip having a rectangular light emitting surface oriented to face the rear surface of the convex lens, and a corner of the rectangular light emitting surface is disposed on a rear focal point of the convex lens. A front surface of the convex lens includes a horizontally diffusing region which diffuses a part of the light in the horizontal direction, and an obliquely diffusing region which diffuses another part of the light toward the self lane side in an oblique direction forming an upward angle with respect to the horizontal plane. | 01-01-2009 |
20110063865 | LIGHT EMITTING MODULE AND VEHICLE LAMP - A light emitting module includes: a circuit board having a shape in which an outer peripheral edge of the circuit board corresponds to an outer peripheral edge of the circuit board before rotating the circuit board about a center point by an angle of 90 degrees in a direction orthogonal to a thickness direction of the circuit board; a semiconductor light emitting element; and a first and second electrodes that are formed on the circuit board at positions symmetrical to each other with respect to the center point. | 03-17-2011 |
20120287658 | VEHICLE LAMP - A vehicle lamp includes: an LED mount on which an LED is placed; an attachment that fixes the LED to the LED mount; a power supply that supplies power to the LED; a first optical member that controls light emitted from the LED; and a second optical member that controls light emitted from the first optical member. The power supply and the first optical member are provided at the attachment. | 11-15-2012 |
20140092618 | OPTICAL UNIT - An optical unit includes a lens through which light emitted from a light source enters from behind and the light emits frontward as an irradiation beam. A rotation lens moves periodically, and a front part is scanned with the irradiation beam, so that a predetermined irradiated region can be formed. The rotation lens may be configured such that the lens rotates about a rotation axis connected to a drive part and such that the direction of light, which emits from the light source and is then refracted when the light passes through the lens, varies periodically. | 04-03-2014 |

20140340909 | LAMP UNIT AND LIGHT DEFLECTING DEVICE - A light deflecting device includes a micro-mirror array and a transparent cover member arranged in front of a micro-mirror array reflective surface. Each of a plurality of mirror elements of the micro-mirror array is selectively switched between a first reflecting position in which the mirror element reflects light such that the reflected light is effectively used as part of a predetermined light distribution pattern, and a second reflecting position in which the mirror element reflects light such that the reflected light is not effectively used. The cover member is configured such that a second angle formed between a mirror element reflective surface when the mirror element is in the second reflecting position and a cover member surface is smaller than a first angle formed between the mirror element reflective surface when the mirror element is in the first reflecting position and the cover member surface. | 11-20-2014 |
20150085514 | VEHICLE HEADLAMP - A vehicle headlamp includes a light source, a projection optical member, and a light deflector. The projection optical member projects incident light ahead. The light deflector is disposed on an optical axis of the projection optical member and includes plural optical devices which are individually switchable between (i) a first state in which light emitted from the light source is reflected to a direction other than a direction toward the projection optical member and (ii) a second state in which the emitted light is reflected toward the projection optical member. An angle between a normal line to a center portion of each optical device when each optical device is in the first state and the optical axis is smaller than that between a normal line to the center portion of each optical device when each optical device is in the second state and the optical axis. | 03-26-2015 |
20150092435 | VEHICLE HEADLAMP - A vehicle headlamp includes a light source, a projection optical member, a light deflector, and a tube shaped housing. The projection optical member projects light, which is incident on the projection optical member, ahead. The light deflector includes a plurality of optical devices that are arrayed. The optical devices are individually switchable between a first state and a second state. In the first state, the optical devices reflect light emitted from the light source to a direction other than a direction towards the projection optical member. In the second state, the optical devices reflect the emitted light towards the projection optical member. The light deflector is disposed inside the housing. The projection optical member is disposed in an opening portion of the housing. A first portion, of the housing, intersecting a path of a light beam incident on the light deflector is transparent. | 04-02-2015 |
