Abstract
A method of illuminating a commercial vehicle in low-light conditions includes providing a camera monitor system that includes a scattered IR LED with a first beam angle and a focused IR LED with a second beam angle smaller than the first beam angle. The method includes operating the scattered IR LED in a first condition to provide a diffused IR light alongside the commercial vehicle, and operating the focused IR LED in a second condition that is different than the first condition to provide a focused IR light to an end of the commercial vehicle.

A method of illuminating a commercial vehicle in low-light conditions, comprising:
- providing a camera monitor system including a scattered IR LED with a first beam angle and a focused IR LED with a second beam angle smaller than the first beam angle;
- operating the scattered IR LED in a first condition to provide a diffused IR light alongside the commercial vehicle;
- and
- operating the focused IR LED in a second condition different than the first condition to provide a focused IR light to an end of the commercial vehicle.
A camera arm for a vehicle camera monitor system for a vehicle with a trailer, comprising:
- a housing;
- a camera mounted to the housing and configured to provide a field of view along a trailer;
- a scattered IR LED in proximity to the housing and including at least one of a scattered primary optic and a scattered secondary optic configured to deliver a diffused IR light to a first target area, the scattered IR LED has a first beam angle at which the scattered IR LED light intensity reaches 50% of its maximum light intensity;
- and
- a focused IR LED in proximity to the housing and including at least one of a focused primary optic and a focused secondary optic configured to deliver a focused IR light to a second target area, wherein the second target area is of a vertical target area that is a distance of 14 m to 22 m from the focused IR LED configured to be adjacent to an end of a trailer and 0.5 m to 1.5 m from a ground on which the trailer rests and including a portion of the ground and vehicle between the vertical target area and the focused IR LED itself, the focused IR LED has a second beam angle at which the focused IR LED light intensity reaches 50% of its maximum light intensity, wherein at least one of the scattered and focused primary optics and the scattered and focused secondary optics are different than one another to provide the second beam angle smaller than the first beam angle.
