Cool music does not stand in the field of smart micro-investment, relying on the tenth day, the product quality and user experience in the first ingenuity. It took less than a month to go public, and Cool Music regards the R4 as a dragon, rolling in the sea of the smart micro-investment industry and turning it over! In addition to the 1920*1080P physical resolution (rectangular pixels) and the 880 ANSI clear highlight experience, there is also a stunning effect of Cora's unmatched optical technology.
In the visual world of cool music, the color is rich and real, can restore the original authenticity of the image to the maximum extent, and naturally, the new fever-class family intelligent micro-projection hospital R4 series, spare no effort to "full HD universal" and "Real Vision" as the main game!
The ultimate reality of the R4, first of all thanks to the new lens design. This time, Cool LeTV invited senior optical expert Ma Yongzhen. Since the beginning of his career, Mr. Ma Lao has always insisted on using pure light to restore the essence of the world and coincides with the concept of Cool LeTV.
Mr. Ma Yongzhen used to be the senior optical expert of Lida Optoelectronics of the former China National Optical Group. He is also an optical core designer of a number of film engineering machines and professional projectors at home and abroad. He is a pioneer in the optical research field of projectors!
At the beginning of the lens design, Mr. Ma Lao has considered the problem of thermal defocusing, virtual focus, and running coke of the intelligent micro projector, so he chose a very good heat resistant all-glass lens on the material, a total of 7 combinations Each piece has been artificially polished and polished, the light transmission performance is excellent, and the control of distortion and edge sharpness is very good in imaging. Compared to the lenses using resin lenses, there is absolutely no picture distortion, and the phenomenon of thermal defocusing is eliminated.
In addition, Mr. Ma Yongzhen also equipped the lens with a precision-milled all-metal lens barrel, connecting the R4 body and lens, making the lens more robust and reducing the number of repeated focusing, and at the same time effectively reducing the light source light scattering, so that every beam of light gets Take advantage of.
This high-performance, short-throw lens also ensures a 1.2:1 throw ratio and can easily project a large 100-inch screen at a distance of just 2.53 meters. This time, Cool LeTV's cooperation with Mr. Ma Yongzhen has opened a new product model and I believe that it will appear more and more in the following cool LeTV products.
But relying solely on the lens, it is not enough to guarantee the R4's screen effect. In the light source and optical channel, R4 has also made innovations: 8A high-current LED light source, high efficiency and high density to ensure high brightness, overcurrent drive technology to fully protect the circuit, more importantly, the first to adopt the new RGGB four-channel design, relative In the RGB three-channel projector, a more light source base color, making the picture more colorful, wide and accurate, given the high brightness of R4 880ANSI lumens, the actual brightness performance is far more than 1000 lumens level of intelligent micro-projection!
In order to ensure the sense of reality, Cool Lexus has also put in as many as 11 image optimization technologies for R4. The application of HDR high dynamic range technology has improved the range of R4's launch screen color. The dark contrast is obviously rich and the visual is restored. The most real feelings.
Cool music as the R4 series of optical world, enough to use high-definition, highlight, real, rich to describe, this is cool music as smart micro-investment in the world of masterpieces and pride. Do you enjoy the best image quality and color performance, not every user's dream?
