Headlight apparatus

A headlight apparatus configured to irradiate illumination light onto a road surface on which a vehicle travels includes a visible radiation lighting unit and a projector lens. The visible radiation lighting unit generates illumination light. The projector lens is provided on an optical axis of the visible radiation lighting unit, and is configured to distribute and project the illumination light irradiated from the visible radiation lighting unit. The visible radiation lighting unit has an LED, a liquid crystal display panel, and a shutter. The LED emits light. The liquid crystal display panel controls light distribution of the illumination light emitted from the LED. The shutter is provided between the liquid crystal display panel and the projector lens, and is configured to shield the liquid crystal display panel from solar light that enters through the projector lens.

LED lamp

An LED lamp includes a lamp base for insertion into a reflector of an automotive front lighting assembly; a panel extending from the lamp base with a first vertical side facing into one half of the reflector and a second vertical side facing into the other half of the reflector; a primary light source including a set of LED dies on each vertical side of the panel; a two-part shield including a first shield half shielding the LED dies on the first vertical side of the panel and a second shield half shielding the LED dies on the second vertical side of the panel. The two-part shield essentially has the form of a shield in a functionally equivalent filament lamp for providing a low beam. A lighting arrangement includes such an LED lamp; a reflector to receive the lamp; and an electrical interface for connecting to a controller.
