Lighting elements with white-color indicator
Apparatus and associated methods relate to providing clear indication of a color of a white-color light of a lighting element. To do so, a white-color indicator is affixed to the lighting element, which has a base, an illumination element, and a lens extending from the base and with the base surrounds the illumination element. The base of the lighting element is configured to physically and electrically connect with a socket of a lighting display. The illumination element is configured to provide white-color light in response to the base receiving electrical power from the socket. The lens is configured to transmit the white-color light of the illumination element therethrough. The white-color indicator is of a color that indicates the color of the white-color light of the illumination element, thereby providing clear indication of the color of the white-color light of the lighting element.
1. A lighting element with white-color indicator, the lighting element comprising:
a base configured to mechanically and electrically connect with a socket:
an illumination element configured to provide white-color light of a chromaticity of white color in response to the base receiving electrical power from the socket;
a lens extending from the base, the lens together with the base surrounding the illumination element, the lens configured to transmit the white-color light of the illumination element therethrough; and
a white-color indicator comprising an elastic band circumscribing either the base or the transparent lens, the elastic band of a color that indicates the chromaticity of the white-color light of the illumination element.
2. The lighting element of claim 1 , wherein the white-color indicator is a warm color so as to indicate a warm color of the white-color light.
3. The lighting element of claim 1 , wherein the white-color indicator is a cool color so as to indicate a cool color of the white-color light.
4. The lighting element of claim 1 , wherein the white-color indicator is white so as to indicate a pure white color of the white-color light.
5. The lighting element of claim 1 , wherein:
the white-color light of the illumination element has an (x WHITE-COLOR , y WHITE-COLOR ) chromaticity on an xy-chromaticity diagram;
the white-color indicator has a color having an (x INDICATOR , y INDICATOR ) chromaticity on the xy-chromaticity diagram; and
the (x WHITE-COLOR , y WHITE-COLOR ) chromaticity and the (x INDICATOR , y INDICATOR ) chromaticity lie on a vector in the xy-chromaticity diagram that includes a (x PURE-WHITE , y IPURE-WHITE ) chromaticity of pure white.
6. The lighting element of claim 5 , wherein the (x INDICATOR , y INDICATOR ) chromaticity of the color indicator lies on a point at a peripheral boundary of the xy-chromaticity diagram.
7. The lighting element of claim 6 , wherein the (x INDICATOR , y INDICATOR ) chromaticity of the is given by:

8. The lighting element of claim 1 , wherein the white-color indicator is visible when the lighting element is physically and electrically connected to the socket.
9. The lighting element of claim 1 , wherein the elastic band is located proximate an interface between the transparent lens and the base.
10. The lighting element of claim 1 , wherein the elastic band contacts mating surface of the lighting element in an uninterrupted fashion around the lighting element, thereby forming a sealed interface therewith.
11. The lighting element of claim 10 , wherein the elastic band is configured to contact a mating surface of the socket in an uninterrupted fashion when the lighting element is physically and electrically connected thereto, thereby forming a sealed interface therewith.
12. The lighting element of claim 11 , wherein the elastic band is configured to inhibit water ingress into the socket when the lighting element is physically and electrically connected thereto.
13. The lighting element of claim 11 , wherein the elastic band is configured to facilitate retention of the lighting element when the lighting element is physically and electrically connected to the socket.
14. The lighting element of claim 1 , wherein the lens is transparent such that the color of the white-color light of the illumination element is unchanged by transmission therethrough.
15. A method of indicating a color of a white-color light of a lighting element, the method comprising:
providing a lighting element having a base, an illumination element, and a lens extending from the base, the lens together with the base surrounding the illumination element, the base configured to mechanically and electrically connect with a socket, the illumination element configured to provide white-color light of a chromaticity of white color in response to the base receiving electrical power from the socket, and the lens configured to provide transmission of the white-color light of the illumination element therethrough; and
circumscribing the lighting element with a white-color indicator comprising an elastic band circumscribing either the base or the transparent lens, the elastic band of a color that indicates the chromaticity of white-color light of the illumination element.
16. The method of claim 15 , wherein the white-color indicator is a warm color so as to indicate a warm color of the white-color light.
17. The method of claim 15 , wherein the white-color indicator is a cool color so as to indicate a cool color of the white-color light.
18. The method of claim 15 , wherein the white-color indicator is white so as to indicate a pure white color of the white-color light.
