The High-mast Lamp is generally refers to the new lighting device which is composed of the steel taper light pole and the high power combination lamp frame of 15 meters or above.It consists of lamp holder, internal lamp, electric rod body and basic part.Lamp head modelling can according to user requirement, surroundings, lighting need specific and definite;The interior lamps are mainly composed of floodlights and projection lamps. The light source adopts NG400 high pressure sodium lamp, and the lighting radius is 60 meters.The bar body is usually a pyramid structure, which is made of steel plate, with a height of 15 to 40 meters, which consists of two to three sections.

At the Consumer Show in Las Vegas, Sharp and Samsung both launched 8K resolution TV prototypes. A considerable number of experts and TV enthusiasts have stated that high resolution is not the only focus of TV display. In order to produce higher quality products, many parameters are often required to interact with each other. Color gamut, brightness, contrast, and more are all very important. If the resolution has reached a level, these parameters tend to be more important than the resolution.
However, to be sure, the display technology will certainly develop to a degree that our naked eye cannot recognize. For example, Apple introduced the revolutionary Retina retina display technology in 2010. At the time, Steve Jobs proposed a realistic standard for retina. He believes that if it exceeds 300 pixels per inch, the viewing distance is normal. It is not enough for the naked eye to distinguish the picture. According to this standard, the vast majority of screen users in 4K resolution cannot be distinguished. It will be the ultimate human eye.

4K resolution is the limit of the human eye can not identify 4K or more screen
With the 2014 CES show just finished, 4K TV will grow faster than expected. Netflix has already planned to launch some online USB streaming video content this year, and Amazon also announced that it will use 4K HD technology to shoot original dramas this year. Obviously, the days when 4K TV became the master of flat-panel televisions are not far away. In today's 8K technology display screen that has not yet been popularized in 4K TVs, it has already been published. Some people may indicate that the 4K or more screens cannot be adapted to human eyes.
