A light emitting diode (LED) module with improved thermal characteristics is provided. The module includes an LED, a first circuit board, a second circuit board, a lower insulator, an upper insulator, a lower contact, upper contacts, and a heat sink. Preferably, the heat sink comprises an outer housing and a contact ring. The LED and the heat sink are attached to the first circuit board via solder. In addition to serving as a substrate for the LED, the first circuit board (which contains a plurality of thermally conductive layers connected by vias) facilitates the transfer of heat away from the LED to the heat sink. The module also has improved mechanical and electrical properties, including redundant electrical connections, stable mechanical connections, and a shock-absorbing lower contact. The lower insulator can also be configured to prevent misalignment of the power source with the lower contact when the module is used in a flashlight or other lighting device.

An illumination apparatus includes a light-emitting element, a first lens, and a second lens. The first lens faces the light-emitting element, and has a radiation port from which a light beam is radiated, a first incident surface, a second incident surface, a first reflection surface, and a second reflection surface. The second lens faces the radiation port. The first incident surface faces the light-emitting element, and guides a light beam from the light-emitting element to the radiation port. The second incident surface guides a light beam not passing through the first incident surface to a direction toward the outer periphery of the first lens. The first reflection surface reflects a light beam from the second incident surface to guide the light beam to the radiation port. The second reflection surface reflects a light beam passing through the first incident surface and then deviating from the direction toward the radiation port, and a light beam reflected on the first reflection surface and then deviating from a direction toward the radiation port, to guide these light beams to the radiation port.

An accent lamp (10) having a solid state light source (4), such as LEDs, is attachable to a rear surface of an automotive headlamp (40) opposite the light-generating capsule (44). Accent lamp (10) has first retaining member (20), such as a clamp, formed above printed circuit board (8) on which LED (4) is mounted. Headlamp base (60) defines light passageway (45), formed as a light guide (42), extending from outermost peripheral surface (63) to an upper surface (61) on which lamp capsule (44) is retained. Accent lamp (10) is readily detachably mounted to headlamp (40), preferably by resilient first and second retaining members (20, 24), and, when mounted, can be biased to promote optical coupling of light source (4) to light guide (42).

In the event that a predetermined illuminance is obtained by illuminating a certain area with light of a first light quantity, an illumination control system illuminates the area with light of a second light quantity which is larger than the first light quantity at a period, and at periods which follow the period, the illumination control system illuminates the area with light of a third light quantity of light which is smaller than the first light quantity.

A motor vehicle headlamp includes numerous semiconductor light sources disposed in a matrix, which can be activated individually for emitting light, numerous primary lenses disposed in a matrix, allocated to the semiconductor light sources, for bundling the light emitted by the semiconductor light sources and for generating a primary light distribution on light exit surfaces of the primary lenses, and a shared secondary lens for projecting the primary light distributions as secondary light distributions onto a roadway in front of the motor vehicle, such that the secondary light distributions illuminate a high-beam region. To reduce the structural height of the secondary lens without losses in terms of efficiency, the motor vehicle headlamp includes a cylindrical lens having a cylinder axis disposed in the beam path of the light module between the primary lenses and the secondary lens that is oriented such that it is substantially horizontal.
