Multicolored LED vehicle interior light
View Patent ↗A multicolored LED vehicle interior light is described. In various implementations, a switch is used to select one of a plurality of LED lights, in which one light is of a color, such as red, which is suitable for preserving night vision.
1. An aircraft cockpit light comprising:
a housing comprising a generally frusto-conical exterior portion and a lip that is disposed annularly about a first end of the frusto-conical portion;
a rotating bezel attached to a second end of the frusto-conical portion;
a lens coupled to the bezel;
a plurality of light-emitting diodes disposed such that, when illuminated, light from the light-emitting diodes passes through the lens and is focused thereby, wherein the plurality of light-emitting diodes includes a first light-emitting diode and a second light-emitting diode, wherein each of the first and second light-emitting diodes emit light of a different color from the other; and
a switch coupled to the bezel, wherein when the bezel is rotated to a first position, the switch permits current to flow to the first light-emitting diode, but not to the second light-emitting diode, and when the bezel is rotated to a second position, the switch permits current to flow to the second light-emitting diode, but not to the first light-emitting diode.
2. The light of claim 1 , wherein the light is disposed within an aircraft cockpit.
3. The light of claim 1 , wherein the first light-emitting diode emits red light when illuminated and the second light emitting diode emits white light when illuminated.
4. The light of claim 1 , wherein the first light-emitting diode emits a light that is suitable for preserving night vision.
5. The light of claim 1 , further comprising an input unit electrically coupled to the switch.
6. The light of claim 5 , wherein when the bezel is rotated to the first position, the switch creates an electrical path between the input unit to the first light-emitting diode.
7. The light of claim 6 , wherein when the bezel is rotated from the first position to the second position, the switch breaks the electrical path between the input unit and the first light-emitting diode and creates an electrical path between input unit and the second light-emitting diode.
8. The light of claim 7 , wherein the first light-emitting diode emits red light when illuminated and the second light emitting diode emits white light when illuminated.
9. The light of claim 8 , wherein the light is disposed within an aircraft cockpit.
10. The light of claim 9 , wherein the first light-emitting diode emits red light when illuminated and the second light emitting diode emits white light when illuminated.
11. A lighting system comprising:
an aircraft cockpit;
a reading light disposed within the aircraft cockpit, the reading light comprising:
a housing comprising a generally frusto-conical exterior portion and a lip that is disposed annularly about a first end of the frusto-conical portion:
a rotating bezel attached to a second end of the frusto-conical portion;
a lens coupled to the bezel;
a plurality of light-emitting diodes disposed such that, when illuminated, light from the light-emitting diodes passes through the lens and is focused thereby, wherein the plurality of light-emitting diodes includes a first light-emitting diode and a second light-emitting diode, wherein each of the first and second light-emitting diodes emit light of a different color from the other, wherein the second light-emitting diode emits light of a color that inhibits the loss of night vision; and
a switch coupled to the bezel, wherein when the bezel is rotated to a first position, the switch permits current to flow to the first light-emitting diode, but not to the second light-emitting diode, and when the bezel is rotated to a second position, the switch permits current to flow to the second light-emitting diode, but not to the first light-emitting diode.
12. The lighting system of claim 11 , wherein the first light-emitting diode emits red light when illuminated and the second light emitting diode emits white light when illuminated.
13. An aircraft cockpit light comprising:
a rotating bezel;
a lens coupled to the bezel;
a plurality of light-emitting diodes, consisting of a red light-emitting diode and a white light-emitting diode, the red and white light-emitting diodes disposed such that, when illuminated, light from the light-emitting diodes passes through the lens and is focused thereby; and
a switch coupled to the bezel, the bezel having a first position and a second position, wherein when the bezel is rotated to the first position, the switch permits current to flow to the red light-emitting diode, but not to the white light-emitting diode, and when the bezel is rotated to the second position, the switch permits current to flow to the white light-emitting diode, but not to the red light-emitting diode.
