Linear lamp replacement
A lighting apparatus is provided having one or more light emitting diodes arranged in a row. The light emitting diodes may be supported by an elongated body. The elongated body may comprise an optical element formed from an at least partially optically transmissive material. The lighting apparatus has two ends and may have electrical connectors at the ends.
1. A lighting apparatus comprising:
a plurality of light emitting diodes arranged in one row and extending along an elongated body;
wherein the elongated body comprises an optical element formed from an at least partially optically transmissive material supporting the light emitting diodes;
wherein the at least partially optically transmissive material comprises a phosphor proximate to the light emitting diodes configured to convert a portion of the light emitted by the light emitting diodes to a longer wavelength;
wherein the lighting apparatus contains exactly two ends with electrical connectors at each end;
wherein the sides of the elongated body are exposed to an ambient environment and are free of fins or protrusions in the exterior of the body;
wherein the elongated body transfers heat from the light emitting diodes to the ambient environment through the at least partially optically transmissive material;
wherein the light emitting diodes are in direct contact with the at least partially optically transmissive material; and
wherein at least one of the light emitting diodes is configured to produce light in the visible range, the ultraviolet range, or the near infrared range, or a combination thereof.
2. The lighting apparatus of claim 1 wherein at least one of the light emitting diodes is configured to emit a color temperature that is different from the other light emitting diodes.
3. The lighting apparatus of claim 2 wherein the color and proportion of different groups of light emitting diodes is configured to achieve a desired correlated color temperature (CCT).
4. The lighting apparatus of claim 1 wherein at least one of the light emitting diodes is configured to emit blue light.
5. The lighting apparatus of claim 1 wherein at least one of the light emitting diodes is configured to emit white light.
