On July 20th, Texas Instruments DLP Products Division displayed the latest affordable 3D projectors in Beijing. In addition, in order to meet the growing demand for projections in teaching and conferences, Texas Instruments DLP Products recently demonstrated the world's first high-brightness bulb-free data projector at the "InfoComm2009 Exhibition" in the United States. It is reported that the brightness of this product can be It reaches 1000 lumens and is suitable for small and medium-sized conference rooms with an area of ​​about 20 inches.
Light projection technology company Wavien has developed a new LED projection technology that uses a 50 watt white LED light source to boost brightness to 200 ANSI lumens. The technology is mainly used in pico projectors and has begun mass production. The new technology can double the brightness of existing LED light source technology and reduce the cost of the projection light source. Wavien said they will not give up their efforts on LED products, and next year they will introduce products with brightness exceeding 300 ANSI lumens.
In the home theater market, Lixun's first high-definition LED home theater projector, the H9080FD, replaces the color wheel and projection bulb in a traditional DLP projector with the PhlatLight PT120 LED chipset and the OSRAM REPCURF9030A drive component. Since there is no high heat problem of the projection bulb, it can be turned on and off like ordinary household appliances, without preheating and cooling, and the service life can reach more than 10 years.
In 2008, Optoma launched the world's first DLP pico projector equipped with LED tri-color light source output - PK-101, weighing only 80g (without battery), can be connected to mobile phones, MP4 and other multimedia devices, users can drink coffee Briefing presentations on the office and official vehicles.
Considering the needs of business and individual users, LED light source has begun to be applied to mini projectors and has become the ultimate device for digital lifestyle. It is only slightly larger than the palm of your hand. You can carry out various business presentations with you, or put them on your hands. A display terminal for home entertainment in the bedroom.
DBS diode series patch rectifier bridge stack is composed of 4 rectifier diodes connected and packaged in the form of a bridge full-wave rectifier circuit, which belongs to a full bridge. There are four lead-out pins, the connection point of the negative poles of the two diodes is the "positive pole" of the DC output terminal of the full bridge, and the connection point of the positive poles of the other two diodes is the "negative pole" of the DC output terminal of the full bridge. Reverse repetitive peak voltage range: 50V~1000V, average rectified output current 0.8A~1.5A: forward non-repetitive surge current 30A (60Hz sine wave, one cycle, Tj=25°C). For specific parameters, please refer to the specification or consult online customer service.
