Abstract

An operatory light may comprise a bulb that includes a light emitting diode (LED) module positioned such that when the bulb is installed into a socket of the operatory light and powered, none of the light emitted from the LED is directed directly toward a lens of the operatory light, and only reflected light passes through the lens of the operatory light.

First claim

What is claimed is:

1 . An operatory light comprising:
a bulb that includes an LED module positioned such that when the bulb is installed into a socket of the operatory light and powered, none of the light emitted from the LED module is directed directly toward a lens of the operatory light, and only reflected light passes through the lens of the operatory light.

2 . The operatory light of claim 1 , further comprising a heat sink coupled to the LED module.

3 . The operatory light of claim 2 , further comprising control circuitry located within a cavity of the heat sink.

4 . The operatory light of claim 2 , wherein the heat sink further comprises a plurality of fins.

5 . The operatory light of claim 2 , wherein the bulb further comprises:
a base coupled to the heat sink via a plurality of legs, wherein the base of the bulb is installed into the socket of the operatory light

6 . A bulb comprising:
an LED module positioned on a heat sink; and a base connected to the heat sink and configured to couple with a socket of an operatory light; and wherein the LED module is oriented to direct light toward the base.

7 . The bulb of claim 6 , further comprising control circuitry located within a cavity of the heat sink.

8 . The bulb of claim 6 , wherein the heat sink further comprises a plurality of fins.

9 . The bulb of claim 6 , wherein the base is connected to the heat sink via a plurality of legs.
