SIGNALING LIGHT WITH MOTION-SENSING LIGHT CONTROL CIRCUIT
First Claim
Patent Images
1. A portable light comprising:
- a housing configured for holding a lighting element and a portable power source; and
an electrical circuit coupled to the housing, the circuit configured for sensing motion of the housing and causing the lighting element to emit light in response to movement of the housing in a first direction and to switch off or dim in response to movement of the housing in a second direction opposite to the first direction.

Abstract
A signaling light, such as a wand light or flashlight, includes a motion sensor coupled to a controller for lamp intensity. When the light is moved in a first direction, the lamp is powered at a baseline intensity. When the light is moved in a second direction generally opposite the first direction, the lamp is switched off or dimmed. When swung in a back-and-forth motion, the light as controlled by the controller thereby appears to move in only one direction, thereby providing a signal indicating a direction of motion.

14. A method of using a portable light as a signaling device indicating a signaled direction comprising:
-
alternatively moving a portable light in first direction and a second direction opposite to the first direction to indicate a signaled direction generally in the direction of the first direction; and operating a circuit coupled to the portable light, the circuit operative to sense the first and second directions of movement of the portable light and to cause the portable light to emit light in response to movement of the housing in the first direction and to switch off or dim in response to movement of the housing in the second direction - View Dependent Claims (15, 16, 17)

18. A circuit assembly for controlling light emitted from a portable light, the assembly comprising:
-
a substrate; an electrical circuit coupled to the substrate and configured for causing a light connected to the electrical circuit to emit light in response to movement of the substrate in a first direction and to switch off or dim in response to movement of the substrate in a second direction opposite to the first direction. - View Dependent Claims (19, 20, 21, 22)
