| 340815730 | With lamp enclosed in transparent housing | 9 |
| 20090195403 | OPTICAL WARNING DEVICE - An optical warning device comprising a light source located within a housing having a wall, a top and a base, the base supporting the light source positioned in front of a reflector to transmit light through a light transmitting surface forming part of the wall of the housing, the top of the housing including an absorber comprising an outwardly facing light shielding surface and an inwardly facing surface profiled to entrap light. | 08-06-2009 |
| 20100007508 | LIGHTING CONTROL HAVING AN IDLE STATE WITH WAKE-UP UPON ACTUATION - A load control device for controlling the amount of power delivered from an AC power source to an electrical load, the load control device comprising a bidirectional semiconductor switch operable to be coupled in series electrical connection between the source and the load, the semiconductor switch having a control input; a controller operatively coupled to the control input of the semiconductor switch for controlling the amount of power delivered to the load; an actuator operatively coupled to the controller such that the controller is operable to determine a desired amount of power to be delivered to the load in response to actuations of the actuator; and a visual display responsive to the controller; wherein the controller is operable to illuminate the visual display to a first intensity upon actuation of the actuator and to subsequently illuminate the visual display to a second intensity less than the first intensity after a predetermined amount of time has elapsed since the actuation of the actuator. | 01-14-2010 |
| 20100109900 | Warning light device having at least two warning lamps - A warning light device having a first warning lamp exhibiting at least one first light unit with at least one first lighting element for visually indicating at least one operating state of a first technical unit having a first electronic control device and having at least one indicating unit for visually indicating at least one operating state, especially several different operating states of the first warning lamp, wherein at least one electronic warning lamp connection is provided for transmitting data and/or control signals at least between the first warning lamp and the indicating unit to provide for the monitoring of several different technical units with considerably less expenditure than in the prior art. This is achieved by the fact the indicating unit is constructed as signaling column having at least one second alternating module with at least one second lighting element. | 05-06-2010 |
| 20140043169 | WARNING LAMP - A warning lamp has a base, a luminous module, a lampshade, and a reflector. The luminous module is mounted in the base and is located in a center segment of the base. The lampshade is combined with the base and has a lucent portion that is formed on a sidewall of the lampshade. The reflector is mounted in the lampshade and has a cone portion protruding toward the luminous module, a first surface facing the lucent portion, and a reflective portion formed on the first surface. The light emitted from the luminous module irradiates the reflective portion. The reflective portion reflects the light emitted from the luminous module to pass through the lucent portion. Accordingly, the warning lamp has a luminous effect in a circular form. | 02-13-2014 |
| 20140062714 | FLASHING DOORBELL SECURITY LAMP - Methods and systems for indicating the presence of a security system on a building are described. Existing security systems do not adequately provide notice to others that a property is protected by a security system. The methods and systems described herein solve this problem by providing a flashing lamp doorbell that may provide notice that a property is protected by a security system, and may optionally convey status information about the current state of the property. | 03-06-2014 |

| 20100117852 | Multi-Function Flare Device for Populated Areas - The invention disclosed herein is a securely attached portable, wearable device to enhance safety, visibility and communication capability of safety personnel when such personal leave their vehicles. The device provided is configured to be securely attached to the wearer, and is capable of emitting variable visual and audio signals actuated by a control panel component which is designed so that the user can activate various options of visual and audio signals while in flight. The device may further include GPS capability for tracking, activation and deactivation functions. | 05-13-2010 |
| 20100265089 | EMERGENCY LOCATION FINDER - A light system for identifying a target location for emergency vehicles, includes an outdoor light fixture and bulb, and an activation mechanism for selecting and changing between a “constant on” mode, a “constant off” mode, and a “blinking” mode. The system may use a dual use smart bulb that functions with standard hardware at the location for constant on and constant off modes, but is activated to emergency blinking mode by another device. The lighting system may be incorporated into or activated by a security or telephone system for alerting a homeowner or security company when an emergency is indicated at the location. | 10-21-2010 |
| 340815750 | Light source modifier | 2 |
| 20080272928 | SIGNALING LIGHT WITH MOTION-SENSING LIGHT CONTROL CIRCUIT - 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. | 11-06-2008 |
| 20090033512 | User Programmable Architecture for Control of a Light Device Used with an Information Handling System Chassis - An information handing system which includes a processor, memory coupled to the processor, a chassis light device and a lighting control system coupled to the processor and the chassis light device. The lighting control system enables customizable control of the chassis light device. | 02-05-2009 |
