LED reflector optic for an automotive headlight

摘要

The present disclosure is directed to an automotive headlight. In one embodiment, the automotive headlight includes one or more first light emitting diodes (LEDs) and one or more second LEDs, wherein the one or more second LEDs are positioned at about 180 degrees with respect to the one or more first LEDs, wherein the headlight optical axis is about −90 degrees with respect to a LED optical axis of the one or more first LEDs, at least one first reflector, wherein the at least one first reflector redirects light from the one or more first LEDs to an angle of about −90 degrees with respect to a LED optical axis of the one or more first LEDs and at least one second reflector, wherein the at least one second reflector redirects light from the one or more second LEDs to an angle of about −90 degrees with respect to the LED optical axis of the one or more first LEDs.

主权项

1. An automotive headlight, comprising:
one or more first light emitting diodes (LEDs) comprising one or more low beam LEDs and one or more high beam LEDs; one or more second LEDs, wherein the one or more second LEDs are positioned on an opposing side of the one or more first LEDs, wherein the one or more first LEDs and the one or more second LEDs each has a respective optical axis that is approximately perpendicular to a headlight optical axis; at least one first reflector, wherein the at least one first reflector redirects light from the one or more first LEDs in a direction of the headlight optical axis, wherein the at least one first reflector has an average radius of curvature in a horizontal axis that is at least five times greater than an average radius of curvature in a vertical axis; and at least one second reflector, wherein the at least one second reflector redirects light from the one or more second LEDs in a direction of the headlight optical axis.
