Light emitting diode based products

Various exemplary implementations of light emitting diode (LED) based illumination products and methods are disclosed including, but not limited to, glow sticks, key chains, toys, balls, various game accessories, light bulbs, night lights, wall lights, wall switches, wall sockets, wall panels, modular lights, flexible lights, automotive lights, wearable accessories, light ropes, decorative lights such as icicles and icicle strings, light tubes, insect control lights and methods, and lighted air fresheners/scent dispensers. Any of the foregoing devices may be equipped with various types of user interfaces (both “local” and “remote”) to control light generated from the device. Additionally, devices may be controlled via light control information or programs stored in device memory and/or transmitted or downloaded to the devices (e.g., devices may be controlled individually or collectively in groups via a network, glow sticks or other products may be downloaded with programming information that is stored in memory, etc.). Devices also may include sensors so that the generated light may change in response to various operating and/or environmental conditions or a user input. Various optical processing devices which may be used with any of the devices (e.g., reflectors, diffusers, etc.) also are disclosed.

LED retrofit lamp

An LED lamp for mounting to an existing fluorescent lamp fixture having a ballast assembly including ballast opposed electrical contacts, comprising a tubular wall generally circular in cross-section and having tubular wall ends with one or more LEDs positioned within the tubular wall between the tubular wall ends. An electrical circuit provides electrical power from the ballast assembly to the LED(s). The electrical circuit includes at least one metal substrate circuit board and means for electrically connecting the electrical circuit with the ballast assembly. The electrical circuit includes an LED electrical circuit including opposed electrical contacts. Each metal substrate circuit board supports and holds the one or more LEDs and the LED electrical circuit. Each metal substrate circuit board is positioned within the tubular wall between the tubular wall ends. At least one electrical string is positioned within the tubular wall and generally extends between the tubular wall ends. One or more LEDs are in electrical connection with at least one electrical string and are positioned to emit light through the tubular wall. Means for suppressing ballast voltage is included. The metal substrate circuit board includes opposed means for connecting the metal substrate circuit board to the tubular wall ends, which include means for mounting the means for connecting, and the one or more metal substrate circuit boards.

Retrofit LED lamp for fluorescent fixtures without ballast

An energy saving device for an LED lamp mounted to an existing fixture for a fluorescent lamp where the ballast is removed or bypassed. The LEDs are positioned within a tube and electrical power is delivered from a power source to the LEDs. The LED lamp includes means for controlling the delivery of the electrical power from the power source to the LEDs, wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such means for controlling includes means for detecting the level of daylight in the illumination area of said least one LED, in particular a light level photosensor, and means for transmitting to the means for controlling relating to the detected level of daylight from the photosensor. The photosensor can be used in operative association with an on-off switch in power connection to the LEDs, a timer, or with a computer or logic gate array in operative association with a switch, timer, or dimmer that regulates the power to the LEDs. An occupancy sensor that detects motion or a person in the illumination area of the LEDs can be also be used in association with the photosensor and the computer, switch, timer, or dimmer, or in solo operation by itself. Two or more such LED lamps with a computer or logic gate array used with at least one of the lamps can be in network communication with at least one photosensor and/or at least one occupancy sensor to control the power to all the LEDs.

Linear lighting apparatus and methods

Linear lighting systems and methods. In one example, two or more lighting elements having an essentially linear or curvilinear shape are coupled together to form a lighting system. Each lighting element includes a group of LEDs arranged so as to illuminate the essentially linear or curvilinear shape of the lighting element. Each element may include LEDs to generate the same color light, and/or LEDs to generate light of different colors. Additionally, each element may include one or more controllers to control the LEDs so as to create a variety of temporal and/or color-oriented lighting effects. The controller(s) may employ one or more of a variety of control techniques to control the LEDs, such as those involving analog control signals or pulse-width modulated (PWM) control signals. The lighting elements of the system may each be configured as a “stand alone” unit working within the system, producing respective lighting effects that may or may not be coordinated with each other. Alternatively, two or more elements of the system may be configured as addressable lighting elements to facilitate coordination of the elements as a networked lighting system. Any of the foregoing linear lighting systems may be used in a variety of interior or exterior, as well as direct or indirect, lighting applications. In one example, such lighting systems are particularly well-suited as replacements or substitutes for neon lighting installations.
