Abstract

Aspects of the present application relate to a bypass switch for a lamp, such as a surgical or diagnostic lamp. When activated, the bypass switch may act to allow electric power to bypass elements of a control board so that the electric power is provided to the plurality of lamp elements.

Claims

1. A lamp assembly comprising:

a plurality of light sources;

a source of electrical power;

a control board;

a fuse board configured to provide, in accordance with control signals received from the control board, the electrical power, received from the source of electrical power, to the light sources; and

a bypass switch configured to, responsive to activation, transmit an override signal to the fuse board;

wherein the fuse board is configured to, responsive to receipt of the override signal, provide the electrical power, received from the source of electrical power, to the light sources without regard to the control signals received from the control board.

2. The lamp assembly of claim 1 wherein the control board is configured to:

generate, based upon user manipulation, the control signals; and

transmit, to the fuse board, the control signals.

3. The lamp assembly of claim 2 wherein the control signals comprise pulse width modulation signals.

4. The lamp assembly of claim 3 further comprising a light ring wherein the bypass switch is configured to, responsive to activation, provide electrical power to the light ring.

5. The lamp assembly of claim 1 wherein the bypass switch further comprises a button for selective activation of the bypass switch.

6. The lamp assembly of claim 1 further comprising a lamp head, wherein the light sources are mounted within the lamp head.

7. The lamp assembly of claim 6 further comprising a swing arm configured to support the lamp head.

8. The lamp assembly of claim 7 wherein the button is mounted to the swing arm.

9. The lamp assembly of claim 8 wherein the light ring surrounds the button.
