A wearable portable speaker system for mobile electronic devices having at least one speaker capable of connecting to a mobile electronic device and a fixture for housing the at least one speaker. The fixture is formed as a collar having an opening formed therein and the at least one speaker is housed in the fixture so that an output of the speakers is at least partially directed upwards from a top portion of the fixture.
摘要:
A lighting device and system having at least one circuit, the circuit having at least two LEDs connected in series, parallel or anti-parallel configuration and at least one current limiting diode. The device or system may be driven with AC or DC power and may further include a sensor and polarity switching circuit to utilize all LEDs within the circuit when drive by DC power.
摘要:
An AC-driven LED assembly with discretely packaged LEDs being connected in an AC circuit and being sized preferably substantially 2.5 mm or less in length and width, and more preferably 2.0 mm or less; and being mounted to a substrate at a distance from the other of preferably approximately 3 mm or less, and more preferably 2.0 mm or less.
摘要:
A telephone service provider or alarm company, supplies phone-line-power for auxiliary, backup, and/or emergency lighting in residential, commercial and/or industrial facilities at a reasonable charge in exchange for providing, maintaining and ensuring that lighting service and power will be available when needed such as under power failure situations. A phone-line-driven lighting device includes a sensor capable of detecting a primary power source. Once the sensor senses that the primary power source is not present, circuitry connects the device's phone line terminal to a light producing element, in turn powering the light producing element via a telephone line's DC or AC power. Such a device may include a control circuit which responds to a predetermined phone line signal, thereby controlling the operational state of the device. Such a signal could be broadcast in emergency or other informative situation by the provider of the phone line service.
摘要:
An AC LED package and circuits are disclosed along with an AC LED driver. The AC LED circuit may include as few as one LED or an array of anti-parallel LEDs driven with AC power sources and AC LED drivers at various voltages and frequencies. The AC LEDs are pre-packaged in various forms and materials and designed for mains or high frequency coupling in various forms to AC power sources, inverter type drivers or packages. The AC LED driver is a fixed frequency driver that provides a relatively constant voltage output to different size loads within the wattage limitation of the driver and in some cases is a direct mains power source.

摘要:
An AC-driven LED circuit 10 includes a first basic circuit 12 having a first branch 14 and a second branch 16 which connect at first and second common points 18, 20 wherein the common points 18, 20 provide input and output for an AC driving current. Each circuit branch includes two LEDs 26, 28 or 30, 32 connected in opposing series relationship such that either the output or input of each LED in the branch join at branch junctions 34, 36. Improvement in performance and scalability is provided by adding n diodes to a given basic circuit and x cross connecting circuit branch diodes (40, 44) and providing one or more basic circuits (15) in series and or parallel. The basic circuits can be packaged and incorporated into AC LED lighting elements capable of integration with lighting devices or systems.
