The multi-lamp projection display apparatus includes a plurality of detachable lamp boxes each having a lamp used as a light source and a memory; and a control device configured to assign an address of the memory in each of the lamp boxes in accordance with an attaching position of the lamp box and write information into the memory. | 05-14-2009 |
| 20110090470 | LED NIGHT LIGHT WITH PROJECTION FEATURE - An LED night light for night time or dark area use may be arranged as a plug-in wall outlet night light or a direct current that includes projection features to project an image, message, data, logo, and/or time on a ceiling, walls, floor, or other desired surface. The LED night light incorporates optics selected from an optics-lens, convex lens, concave lens, openings, cut-outs, film, grating means, and/or hologram means to create the preferred image and project it to a desired location. | 04-21-2011 |
| 20120008108 | PROJECTION DISPLAY DEVICE - A projection display device includes: a light source; a rod-type integrator which unifies light emitted from the light source in intensity distribution; an imager which modulates the light emitted from the integrator; and an optical axis adjuster for adjusting an optical axis of the light source with respect to an incidence plane of the integrator. In this arrangement, the integrator has the incidence plane formed in the shape of a rectangle and inclines around an optical axis of the integrator with respect to an installation surface of a main body cabinet in which the light source is disposed. In addition, the optical axis adjuster shifts the light source relatively with respect to the incidence plane in a direction parallel to a shorter side of the incidence plane. | 01-12-2012 |
| 20120127439 | PROJECTION APPARATUS, ILLUMINATION MODULE AND BRIGHTNESS ADJUSTING METHOD FOR THE PROJECTION APPARATUS - A projection apparatus, an illumination module and a brightness adjusting method for the projection apparatus are provided. The projection apparatus comprises the illumination module and the actuator. The illumination module comprises a luminous element. First, the actuator drives the luminous element to move from the first position to the second position to detect the first brightness and second brightness generated by the luminous element. When the first brightness is higher than the second brightness, the actuator is adapted to drive the luminous element to the first position. Thereby, the brightness of a projection image generated by the projection apparatus can be adjusted to an optimal value. | 05-24-2012 |
| 20130003027 | PROJECTION APPARATUS AND LIGHT SOURCE ADJUSTING METHOD THEREOF - A projection apparatus including a digital micro mirror device (DMD), a light source, a lens, a photoelectric conversion device, a decision device and an adjustment module is provided. When the DMD is switched to a first operating state, the DMD reflects a light beam emitted by the light source to the lens. When the DMD is switched to a second operating state, the DMD reflects the light beam to the photoelectric conversion device. The photoelectric conversion device generates a signal value according to a light intensity of the light beam. The decision device compares the signal value with a predetermined value. When the signal value is smaller than the predetermined value, the decision device generates a driving signal value. The driving signal value is used for driving the adjustment module to sequentially adjust a position of the light source along a plurality of axes. | 01-03-2013 |
