Abstract

A disclosed bus stop arm includes an extendable arm for protruding from a bus and including signage instructing motorists to stop, a socket in the extendable arm for receiving a lamp, and a lamp having a connector configured to be received in the socket. The lamp includes at least two light emitting diodes, the light emitting diodes projecting light in substantially opposite primary directions. A disclosed lamp for a bus stop arm includes a connector configured to fit in a lamp socket on a bus stop arm, and at least two light emitting diodes. The light emitting diodes project light in substantially opposite primary directions.

Claims

1. A bus stop arm, comprising:

an extendable arm for protruding from a bus and including signage instructing motorists to stop;

a socket in the extendable arm for receiving a lamp; and

a lamp having a connector configured to be received in the socket, wherein the lamp includes at least two light emitting diodes, the light emitting diodes projecting light in substantially opposite primary directions.

2. The bus stop arm of claim 1, wherein the socket includes a bayonet socket and the connector includes a bayonet connector configured to be received in the bayonet socket.

3. The bus stop arm of claim 1, wherein the signage includes two opposing surfaces and each of the at least two light emitting diodes projects light in a primary direction substantially perpendicular to a corresponding one of the surfaces.

4. The bus stop arm of claim 1, wherein the lamp includes a printed circuit board connected to the connector, and the at least two light emitting diodes are mounted on opposite sides of the printed circuit board.

5. The bus stop arm of claim 1, wherein the lamp includes a bridge circuit that allows the connector to be connected to the socket in a plurality of configurations.

6. The bus stop arm of claim 1, wherein the lamp includes a voltage regulator that provides a substantially constant voltage to the light emitting diodes.

7. The bus stop arm of claim 1, wherein the lamp includes a flash controller that causes the light emitting diodes to produce flashing light.

8. A lamp for a bus stop arm, the lamp comprising:

a connector configured to fit in a lamp socket on a bus stop arm; and

at least two light emitting diodes, the light emitting diodes projecting light in substantially opposite primary directions.

9. The lamp of claim 8, wherein the connector includes a bayonet connector configured to be received in a bayonet lamp socket on a bus stop arm.

10. The lamp of claim 9, wherein the light emitting diodes are disposed in a spatial relationship to the bayonet connector such that a predetermined orientation of the light emitting diodes is achieved when the bayonet connector is disposed in a bayonet lamp socket.

11. The lamp of claim 8, comprising a printed circuit board connected to the connector, wherein the at least two light emitting diodes are mounted on opposite sides of the printed circuit board.

12. The lamp of claim 8, comprising a bridge circuit that allows the connector to be connected to the lamp socket in a plurality of configurations.

13. The lamp of claim 8, comprising a voltage regulator that provides a substantially constant voltage to the light emitting diodes.

14. The lamp of claim 8, comprising a flash controller that causes the light emitting diodes to produce flashing light.
