| 20120169233 | DRIVING APPARATUS FOR FLUORESCENT TUBE AND METHOD THEREOF AND ILLUMINATION APPARATUS USING THE SAME - A driving apparatus for a fluorescent tube and a method thereof and an illumination apparatus using the same are provided. The driving apparatus stops providing power, when a fluorescent tube has broken, to both ends of the broken fluorescent tube regardless of whether a power switch related to the fluorescent tube is in ON or OFF state, and thus making sure that a person is under a safety condition without getting an electric shock during replacing the broken fluorescent tube; moreover, the driving apparatus automatically detects the newly installed fluorescent tube and automatically light up the newly installed fluorescent tube after the broken fluorescent tube is replaced and it is unnecessary to switch the power switch related to the fluorescent tube anymore, and thus avoiding a potentially hazard for the person who climbs up and down a ladder repeatedly. | 07-05-2012 |
| 20080297053 | METHOD FOR CONTROLLING DUAL LAMP MODULE - A method for controlling a dual lamp module applied to a projection apparatus is provided. The dual lamp module includes a first lamp and a second lamp. The method for controlling a dual lamp module includes providing a first operating power to the first lamp, and then determining whether the first lamp is turned on or not. If the first lamp fails to be turned on, stopping providing the first operating power to the first lamp, and providing a second operating power to the second lamp. The second operating power is greater than the first operating power. | 12-04-2008 |
| 20120274212 | LED MODULE AND LED LIGHT STRING USING THE SAME - The present invention provides an LED moudle and an LED light string using the same. The LED module has an input terminal, an output terminal, a primary LED, a spare LED and a switching module. The switching module controls the spare LED to be switched off while the primary LED is switched on; and controls the spare LED to be switched on while the primary LED is burned out. Hence, the present invention extends a service life of the LED light string using the LED modules in the backlight module. | 11-01-2012 |
| 20120326609 | MULTIPLE LAMP LIGHTING LEVEL BALLAST FOR SERIES CONNECTED LAMPS - A ballast that selectively operates multiple lamps is provided. The ballast includes a switching network, capable of operating in a number of switching configurations. The ballast also includes a control circuit, and two lamp control switches. The control circuit is connected to the switching network, and provides respective control signals via respective output terminals as a function of the switching configuration of the switching network. Each lamp control switch is in parallel with its lamp and is connected to a respective output terminal. The first lamp control switch is connected to a ballast power supply, and either provides power to the first lamp or does not, depending on the first control signal. The second lamp control switch is connected to the first lamp control switch and to ground, and either provides power to the second lamp or does not, depending on the second control signal. | 12-27-2012 |
| 315090000 | Plural load devices with selective substitution of load device or electrode | 4 |
| 20100156298 | LED Lighting Arrangement - An LED lighting arrangement comprising at least one LED, for producing light is disclosed. A power supply provides power for the at least one LED. At least one control circuit is coupled to the at least one LED in a way that directly or indirectly uses, to power the at least one control circuit, one or more forward voltage drops across the at least one LED. Beneficially, one or more additional control circuits can be added without redesign of the power supply for the at least one LED. | 06-24-2010 |
| 20100117539 | LAMP OPERATION DEVICE AND IMAGE DISPLAY DEVICE - A lamp operation device includes a mode setting part that sets an operation mode for lamps, and a lamp operation part that controls switching between the lamps in accordance with the set operation mode. The lamp operation part includes a process corresponding to a manual switching mode in which a lamp selected by a user is set as an illumination lamp, and a process corresponding to an automatic switching mode in which the plurality of lamps is automatically set in sequence as an illumination lamp. In the automatic switching mode, after one lamp has been set as the illumination lamp, cumulative illuminating time (amount of change) of the lamp is measured. Then, the illumination lamp is switched to the other lamp, depending on whether a measurement result has exceeded predetermined threshold time. | 05-13-2010 |
| 20110316422 | FAILURE MITIGATION IN ARRAYS OF LIGHT-EMITTING DEVICES - In accordance with certain embodiments, an illumination system comprising a plurality of power strings features elements facilitating compensation for failure of one or more light-emitting elements connected along each power string. | 12-29-2011 |
| 20080231196 | Light source of side-edge type LED backlight unit - A light source of side-edge type light-emitting diode (LED) backlight unit for using in a liquid crystal display (LCD) comprises a substantial LED bar, at least one primary LED set preset as the light source of the LCD, and at least one backup LED set. The primary LED set(s) and backup LED set(s) are composed of a plurality of LED and disposed at the LED bar, and a backup LED set will be enlightened and substituted for one primary LED set as the light source when the primary LED set is broken-down so that the light source for the LCD is maintained at constant levels. | 09-25-2008 |
