As LED projectors gradually enter the era of high-definition brightness, they are one step closer to Pu. As an emerging product of the projection industry, many consumers are not very familiar with LED projectors, and they will encounter various problems when purchasing. Especially in the face of the different performance parameters of different types and different models, how can I find a machine that suits me and not be misled by propaganda? Next, let the author say in detail.

Volume: "mini" and "portable" are not the same
Since the beginning of the market, LED projectors have been collectively referred to as pico projectors, also known as pocket projectors. Nowadays, with the continuous improvement of brightness, the size of LED projectors has also increased. It cannot be generalized as a miniature projector. Some bright LED projector products are more accurately called portable projectors.

However, they all have the common feature of making the traditional large-scale projector compact, portable, miniaturized, entertaining, and practical, making projection technology closer to life and entertainment.
However, with the increase of manufacturers and the variety of products, some manufacturers do not have a very accurate classification. For example, the 500-lumen LED projectors introduced on the market in 11 years are larger than the LED projectors listed in previous years. They are not only pockets, but also larger than the palms. They are only suitable for backpacks and handbags. They are not collectively referred to as pico projectors and can only be referred to as portable LED projectors. Therefore, when purchasing a high-brightness LED projector, be sure to find out the size of the machine in order to buy a product that is suitable for your own.
Technology: Display DLP as the main light source with LED as the main
At present, the micro-projector technology can be classified from two aspects: one is divided into LED and laser light source from the perspective of light source; Secondly, it is divided into LCoS technology and DLP technology from the perspective of display chip, wherein the implementation of color by LCoS is divided into color sequence Type and color filter type. However, from the products launched by manufacturers in recent years, LCoS display technology is rarely seen. Therefore, at the time of purchase, the LED projector with only DLP display technology is selected, and the chip has been upgraded to the HD level.
In terms of light source, LED light source is still the main one. It has the advantages of easy control, low-voltage DC drive, rich color performance after combination, and long service life. Especially the life expectancy has reached 30,000 hours this year. In addition, cost, efficiency, industry chain, and so on, are already very mature, so LED has become a push for manufacturers, and the market is also dominated by LED light source products. As for the laser light source, not only does the color not reach a good balance, but also the safety is problematic, so the product is relatively rare, and it does not need to be included in the reference object.
Project lamps is based on the actual needs of the project, customized for the specific lighting products, it plays decorative effect, also known as non-standard lamps, decorative lamps, custom lamps and so on. Engineering lamps feature with custom, long production time, high production technology, strong professionallity , weak liquidity, highly difficult installation, after-sales service and so on.
