Abstract
A vehicle lighting assembly includes a housing, a circuit board, and a lens. The circuit board is disposed within the housing and includes a turn signal light source configured to emit yellow-green colored light at a peak intensity in a range of about 500 nm to about 570 nm. The lens is coupled to the housing. The lens is a single-color optical filter configured to shift the yellow-green colored light emitted from the turn signal light source to a range of about 588 nm to about 592 nm.
Claims18
A vehicle lighting assembly, comprising:
- a housing;
- a circuit board disposed within the housing and including a turn signal light source configured to emit yellow-green colored light at a peak intensity in a range of about 500 nm to about 570 nm;
- and a lens coupled to the housing, wherein the lens is a single-color optical filter configured to shift the yellow-green colored light emitted from the turn signal light source to a range of about 588 nm to about 592 nm, further comprising a brake light source coupled to the circuit board and configured to emit red colored light at a peak intensity in a range of about 612 nm to about 630 nm;
- wherein the lens is configured to allow the red colored light emitted from the brake light source to pass through the lens without a substantial shift in color.
A method of illuminating a vehicle lighting assembly, comprising:
- emitting yellow-green colored light at a peak intensity in a range of about 500 nm to about 570 nm from a turn signal light source coupled to a circuit board of the vehicle lighting assembly;
- and filtering the yellow-green colored light through a single-color optical filter to shift the yellow-green colored light emitted from the turn signal light source to a range of about 588 nm to about 592 nm, further comprising emitting red colored light at a peak intensity in a range of about 612 nm to about 630 nm from a brake light source coupled to the circuit board;
- wherein the single-color optical filter is configured to allow the red colored light emitted from the brake light source to pass through the lens without a substantial shift in color.
A vehicle taillight assembly, comprising:
- a housing;
- a circuit board disposed within the housing, the circuit board including a turn signal light source configured to emit yellow-green colored light at a peak intensity in a range of about 500 nm to about 570 nm and a brake light source configured to emit red colored light at a peak intensity in a range of about 612 nm to about 630 nm;
- and
- a single-color optical filter coupled to the housing and configured to shift the yellow-green colored light emitted from the turn signal light source to a range of about 588 nm to about 592 nm through the filter and allow the red colored light emitted from the brake light source to pass through the filter without a substantial shift in color.
