A lamp for a vehicle includes an array module including a plurality of micro Light Emitting Diode (LED) chips. The array module includes a plurality of regions, where each region includes one or more arrays. Each array includes at least a portion of the plurality of micro LED chips. At least one of the plurality of regions includes arrays that are stacked to each other, where a number of arrays stacked at a first region among the plurality of regions is different from a number of arrays stacked in a second region among the plurality of regions.

Improved light emitting diode (LED) vehicle headlamps having a dedicated daytime running lamp (DRL) component are described. In various embodiments, a combination Low Beam/DRL headlamp is provided, which uses pulse width modulation (PWM) detection to determine which of the two internal LED light sources (Low Beam or DRL) is powered on. If the Low Beam/DRL headlamp detects a PWM signal on the Low Beam voltage input then it switches to drive the DRL LEDs. If, alternatively, it detects a steady state input voltage then it switches to drive the Low Beam LEDs.

A lighting device for vehicles having a housing, in which a light source unit for emitting a light beam and an optical unit associated with the light source unit for generating a predetermined light distribution are disposed, with a cover plate closing an opening of the housing and with a cooling element for dissipating heat from the light source unit. The cooling element is associated with a heat-dissipating optical element of the optical unit. A dividing wall separating the housing into a first chamber and into at least a second chamber is provided, wherein in the first chamber, the first cooling element associated with the light source unit, and in the second chamber, the second cooling element associated with the heat-dissipating optical element of the optical unit are arranged.

An optical unit includes a light source and a rotary reflector that rotates about an axis of rotation while reflecting light emitted from the light source. The rotary reflector is disposed such that the axis of rotation of the rotary reflector intersects a horizontal plane.

Provided is an LED lamp for prevention of freezing, comprising: a housing opened at a front side thereof; an LED unit disposed inside the housing; a lens mounted at the opened front side of the housing and configured to allow lighting light emitted from the LED unit to transmit therethrough; a heating member disposed at the rear side of the lens and configured to generate heat by being supplied with power; a sensor unit disposed at the inside of the housing and configured to sense the internal temperature of the housing; and a control unit configured to control the power supplied to the heating member depending on the internal temperature of the housing, sensed by the sensor unit.

The present invention relates to a lamp, including a half mirror having upper and lower surfaces to reflect a part of light incident on the lower surface and discharge another part to outside, a first reflector located below the half mirror to be vertically spaced so as to face the lower surface of the half mirror, a plurality of light sources to emit light between the half mirror and the first reflector, and a second reflector located between the light sources to reflect at least some of incident light, wherein the half mirror and the second reflector face each other, such that light emitted from a part of the light sources is repeatedly reflected between the half mirror and the second reflector, and wherein the first and second reflectors face each other, such that light emitted from the remaining light source is repeatedly reflected between the first and second reflectors.

A reflecting device includes at least one reflecting cavity corresponding to at least one light source. A first reflecting cavity located at an extremity of the reflecting device includes a first reflecting part, able to receive incident light from the light source corresponding to the first reflecting cavity, and reflect this light towards the second reflecting part. A second reflecting part adjoins the first reflecting part is able to reflect the reflected light from the first reflecting part towards the outside of the first reflecting cavity. The first reflecting cavity at the extremity of the reflecting device may include a first reflecting part and a second reflecting part, which are able to subject light rays from the light source to double reflection. This can considerably increase the design flexibility of the first reflecting cavity.
