| 20090109692 | Light Fixture with Removable Lamp Housing - A lighting fixture having a socket housing and a removable lamp housing. The socket housing includes a socket for receiving a lamp and for connecting the lamp to a power supply. The lamp housing has a first end for emitting light from the lamp and a second end that is removably coupled to the socket housing. The lamp housing least partially encloses the lamp when connected to the socket housing. The second end of the lamp housing is wider than the lamp, so as to allow the lamp housing to be removed from the socket housing without first removing the lamp from the socket. Removing the lamp housing from said socket housing substantially exposes the socket to view and allows for installation of a lamp into the socket without having to re-position or re-aim the track light fixture. | 04-30-2009 |

| 20090109694 | Light Fixture with Lamp Adjustment Assembly - A lamp adjustment assembly for a light fixture includes a socket platform having a base and hollow neck. A socket mounts to the base. The interior of the hollow neck includes at least three spaced-apart cam followers. A cam having spiral grooves includes a first portion that fits at least partially within the interior of the hollow neck. The cam followers mate with the grooves. An adjustment knob is coupled to a second portion of the cam and rotatably coupled to a socket housing that at least partially encloses the lamp adjustment assembly. Alignment wings extend from the base of the socket platform and are sized to fit within slots in the interior of the socket housing. The slots prevent the socket platform from rotating and limit the linear range of motion of the socket platform. A spring applies force to the base and the adjustment knob. | 04-30-2009 |

| 20090085927 | LIQUID DISPLAY DEVICE DRIVING METHOD - The present invention directs to a liquid crystal display device driving method, comprising: compensating data line input voltages according to gate line numbers in which respective TFTs of a liquid crystal panel exist, and outputting the compensated data line input voltage to the liquid crystal panel. The present invention firstly compensates the input voltages according to the gate line numbers in which respective TFTs of the liquid crystal panel exist, and then outputs the compensated input voltages to respective lines of TFTs. The input voltages are gradually increased as the gate line numbers increasing, so as to ensure charging amount of pixels on all gate lines. A charging delay problem due to load difference between a near end and a far end of a high resolution and large size panel is resolved, the uniformity of the panel is ensured, and the display quality of image is improved. | 04-02-2009 |
| 20090243986 | DRIVING METHOD, COMPENSATION PROCESSOR AND DRIVER DEVICE FOR LIQUID CRYSTAL DISPLAY - The invention relates to a driving method, compensation processor and driver device for liquid crystal display. The driving method includes steps of receiving data signal of a present frame; obtaining an average brightness value of the present frame; comparing the previous frame with the present frame, and when the difference between the average brightness values is larger than or equal to a set threshold, generating at least two back light driver pulse signals of which the duty ratios gradually changing, and outputting them to drive the back lights. The compensation processor includes a data analysis module, a data compensation module, a back light linear filtering module and a pulse generator module. The driver device employs the compensation processor of the present invention. The present invention employs the technical means of generating a plurality of back light driver pulse signals, realizes the gradual changing of the brightness of the back lights, and overcomes the picture flickering problem due to the sudden changing of the brightness of the back lights, thus improving the display effect of the LCD. | 10-01-2009 |
