A reflector device to be utilized with light emitting diodes (LEDs), and particularly with high-flux LEDs. In the reflector structure individual reflector portions surround at least one LED. Light output from each individual LED is reflected by sloping walls of each individual reflector portion and is redirected. As a result, light that may otherwise be lost is redirected to a more useful direction. Each individual reflector portion can have a cross-section of a conic shape, a complicated curve, and can also be oval in shape. A light device is realized by utilizing such a master reflector with an LED light source.

Combined lens for clearance sidemarker and identification lamp

Lens for clearance sidemarker and identification lamp

The present invention provides for a lamp assembly which can be utilized in overhead signaling or lighting applications such as in traffic signal lamps or illuminated overhead road signs. The assembly includes a lens that optimizes and redirects light in a desirable direction in order to meet certain regulations. The lens of the present invention is designed to power portions of light emitted from an LED while allowing other portions to pass through the lens unaided. The lens of the present invention works in combination with specific LEDs to efficiently redirect light emitted from the LEDs. The assembly includes a circuit board including a plurality of rows of LEDs and the lens, which has an exterior surface and an interior surface. The interior surface of the lens comprises a plurality of rows of horizontal bands with a single band being associated with a row of the LEDs. Each of the bands has an upper region and a lower region used to redirect some light rays downward, allow some rays to travel uninterrupted and redirect some light horizontally.

The present invention relates to an LED-illuminated lamp assembly which includes a lens that is capable of directing light from the LEDs both horizontally and vertically. The taillight mode is also directed slightly upward so as to comply with applicable lighting regulations. The lamp assembly also includes a current regulating assembly which is mounted within the housing and attached to a power source for providing current to LEDs positioned within the housing. The LEDs are mounted on an LED board assembly. The current regulating assembly is capable of maintaining steady current through the LEDs independent of the power source voltage so as to prevent an overheating of the LEDs at higher than normal voltages and to provide constant, non-flickering light output with varying input voltages.
