If you ask everyone what new appliances you need to buy in your living room, your first reaction must be television, not a projector, and not a LED smart projector. Indeed, unknowingly, television has been entering Chinese families for decades. It almost completely occupied everyone's living room. Although projectors have been the subject of debate since the introduction of projectors, projectors have always been at a disadvantage.
If only from the point of view of function, there is no problem for the projector to access the TV signal through the set-top box. Especially with the development of technology, many projectors have their own intelligent systems, and they can watch television programs by connecting to the network. From the display size, the visual impact of a 100-inch screen is unmatched by the TV. Its display area is equivalent to four 50-inch TVs.
Home projectors do have the advantage of easily projecting large screens and are not inferior to TVs in functionality, but why haven't they been able to replace TVs? In my opinion, early projectors have the following disadvantages compared to television: high prices, high installation costs, high maintenance costs, and low lamp life.
However, since the application of LED light sources in the field of projectors, with the continuous improvement and progress of projection technology, many micro-projectors have broken the monopoly position of traditional projectors, creating a new era of projection without replacement of light bulbs. Gradually solved the above deficiencies with respect to television.
However, there is an important shortcoming for projection to replace TV, which is low brightness. The LED projector brightness refers to the light output of the LED projector and is expressed in terms of luminous flux (the energy that the light source radiates out of the surrounding space per unit time to generate a sense of the human eye). The unit is lumens. For projectors, the higher the number of lumens, the stronger the brightness. The LED projector is difficult to meet the bright environment display requirements due to its brightness, making it more suitable for use in some dark fields.
Although from the end of 2015, the mainstream LED smart projection increased from the previous 300-400 lumens to 550 lumens, although to a certain extent, to enhance the relatively low brightness of the projector relative to television, but the objective exists. Until this year Cool LeTV launched a new flagship S3 smart projector, "the world's first ultra-thousands of lumens of LED smart micro-projection."
Whether this S3 can really reach thousands of lumens, the author has always been in doubt, but after the confirmation of the industry experts, as early as before the release of S3, Cool LeTV came to send new products to Beijing "national digital audio and video and multimedia product quality supervision and inspection Center" test brightness message. After nearly a week of comprehensive testing, the National Audio Video Testing Center finally showed the test results and certificates. The certificate showed that the brightness of the S3 engineering prototype was: 1,081 ANSI lumens, which was indeed worthy of the "Truely Thousand Lumens.
The S3's 1081 ANSI lumens are fully enough to compete with the light bulbs, so the ultra-thousand-lumen cool music as the S3 claims that the smart projection that can be seen during the day is indeed not exaggerated.
Then we searched for the page of Coolcore's crowdfunding in Jingdong. From the 13th of this month, we raised funds in Jingdong. After more than ten days, we have already reached more than 7 million, but we are not surprised to think about it. The ultra-thousand-luminous LED intelligent micro-projection, once sounded, can instantly attract the attention of a large number of fans, not to mention the ultra-low-priced crowdfunding of 1999-2999 with ultra-turbulent lumens and all-around configuration.

An evacuated tube is two glass tubes, one within the other, joined at each end. The space between these tubes is evacuated so the space is under a vacuum seal. Vacuums are excellent insulators (think thermos.) The inner tube is coated with a selective coating that converts light into heat.
Guaranteed for fifteen years (the longest warranty on the market) Linuo tubes are made from high quality borosilicate glass and are fused together. This provides an all glass seal. The Linuo evacuated tube uses a unique three layer selective coating instead of the standard single al-n/al coating. It consists of an infrared emission layer, an absorption layer and an anti-reflective layer, giving a much improved performance.
