摘要： A projection apparatus includes a light source emitting an illuminating beam, a light valve receiving the illuminating beam to create an image beam, and a projection lens system arranged on a path of the image beam for receiving and projecting the image beam onto a screen. The projection lens system includes four lens elements arranged along the optical axis in order from the screen toward the light valve, namely, first, second, third and fourth lens elements respectively having positive, negative, positive and positive refractive power. The four-piece projection lens system satisfies the condition of 0.79

摘要： An LED light converging system includes an LED light source, and first and second lens units aligned in sequence along an optical axis. The LED light source provides source light. The first lens unit has a first focal length, and is disposed forwardly of and is spaced apart from the LED light source by a first distance less than the first focal length such that a virtual image of the source light provided by the LED light source is formed rearwardly of the LED light source. The second lens unit has a second focal length, is disposed forwardly of the first lens unit, and is spaced apart from the virtual image of the source light by a second distance larger than the second focal length such that a real image of the source light provided by the LED light source is formed forwardly of the second lens unit.

摘要： The invention discloses an arrayed light emitting diode (LED) module including multiple LED chips and light-reflecting members. Multiple gaps exist between LED chips adjacent to each other. Each of the light-reflecting members respectively is disposed in one of the gaps. The light-reflecting member reflects the light emitted from the LED chips, to diminish the dark gap shown on the illumination region, further to uniform the brightness distribution of the illumination region.
