Linear lamp replacement

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.
