1 thousand lumens LED projection listed
In 2009, LED light sources are used more and more in the projector market, from ultra-portable projectors up to 1 kilogram to pico projectors with a brightness of only 15 lumens, weighing only about 100 grams, and brightness of 800 lumens, and using 1920 Full HD projectors with 1080 resolutions have already had good product launches. However, the brightness of these products is always difficult to meet the needs of users. The ultra-portable projector with only 150 lumens can only project large screens in a darker environment. The price of Lixun H9080FD with a brightness of 800 lumens is as high as 150,000 yuan. For the majority of consumers, it is still unbearable. So, is there a projector that uses LED light source, which can balance performance and cost performance, and become a product that consumers can afford?
At the beginning of 2010, at the Consumer Electronics Show in the United States, Samsung released the SP-F10M LED light source projector with a brightness of up to 1000 lumens. It surpassed the H9080FD launched by Lixun in 2009 and became the brightest LED light source projector in the industry. Recently, Samsung's projector has been released in China and will soon meet with domestic consumers.
The Samsung SP-F10M projector has a range of 115.6% NTSC color gamut, which allows us to see the huge advantages of LED light source. At the same time, only 158 watts of power and 30,000 hours of light source life make it far beyond the adoption. A projector for traditional light sources.
With the inherent advantages of LED light source, can this product subvert the entire projector industry, so that the traditional light source projector has no way to escape? And whether the launch of this product will make LED light source projector become the mainstream of the market? Below, The author analyzes the following in various aspects, whether the LED light source projector will become the mainstream in the future.
Technology: Multiple advantages lead the traditional light source
Many years ago, LED light sources were highly anticipated. At that time, many people in the industry predicted that LEDs would replace traditional light sources in various fields. What exactly is the LED light source?
LEDs are light-emitting diodes, which are solid-state semiconductor devices that convert electricity directly into light. It has many features such as small size, low power consumption, long service life, low heat dissipation, wide color gamut, etc. These features are also the best choice for becoming a new light source for projectors.
The LED light source is applied to the projector. With the advantages of small size and low heat dissipation, the structure of the projector can be greatly simplified and the volume can be greatly reduced. From the projectors launched in these two years, we can see that the projector with LED light source can be reduced to only 90 grams, and the miniature projection module can be built into handheld devices such as mobile phones and digital cameras. Ultra-portable projectors under 1 kg have become a good choice for personal entertainment.
The LED light source is used in the projector, and the biggest feature is the long life. We all know that the traditional projector has a lamp life of only 3,000 hours, and in the low brightness mode, it can only reach 6000 hours. At the same time, the price of the light bulb is also very expensive, generally around 1000-2000 yuan. It is no wonder that many friends are thinking about buying a projector. They will ask the question "Is the bulb very expensive?" The life of the LED light source is very long. In theory, The longest can last up to 100,000 hours, and the latest Samsung F10M has a lifespan of 30,000 hours, which means that when you buy this projector, you don't need to replace the bulb at all.
In addition, for the projector, the color of the picture is also very important. The color saturation of traditional projectors is generally below 80% of the NTSC color gamut, and the color of the home machine will be slightly better, and the use of LED light sources will greatly increase the color gamut range. In particular, the LED light source of the three primary colors is used, so that the red, green and blue colors have 256 levels of gray and are randomly mixed, and 256×256×256=16777216 colors can be produced. The color saturation of the Samsung F10M we tested reached 115.6% of the NTSC color gamut, which greatly exceeded the color gamut of traditional light sources.
These are just the most important advantages of LED light sources. In addition, the characteristics of mercury-free environmental protection and low power consumption have made it the mainstream light source technology in the future.
Vendor: Lowering costs will disrupt the market
From the manufacturer's perspective, the wide application of LED light source projectors will bring huge development in the projector market. We can see that the current manufacturers of LED light source projectors include Samsung, Lixun, LG, BenQ, Optoma and other manufacturers, especially Samsung and Lixun, both of which are entering the projector market for a few years. With the innovation of technology, it has become the mainstream manufacturer in the projector industry in a short time.
The traditional mainstream projector brand has very few applications for new light sources. At present, there are few products that use LED light sources, and the brand effect and market share in the market are in the overall situation. Although the life of the traditional light source is extended by energy-saving technology, the longest life in the low-light mode is only 6,000 hours.
At the same time, due to the inherent disadvantages of the traditional light source, it is difficult to greatly improve the color saturation. At present, the traditional projector we have evaluated can only achieve 80% NTSC color in the color saturation test. The domain range is difficult to compete with LED light sources in this respect.
Of course, LED light sources also have their own flaws. First of all, the traditional projector uses a point source, which can greatly improve the energy efficiency of the light, and the LED is a surface light source. How to make the light source increase the luminous flux per unit area is a problem that various manufacturers need to solve. We can see that the LED projector with the highest brightness on the market currently has the latest Samsung F10M, but it has only 1000 lumens, while the traditional business projector can easily reach 2000 lumens above brightness. The mainstream products in the market are also at the level of 3000-4000 lumens. In terms of brightness, LED light source projectors still need to be upgraded.
Second, price is the biggest barrier affecting LED light source projectors. We know that in 2009, the world's first 1080p full HD LED projector H9080FD with a brightness of 800 lumens was sold for up to 150,000 yuan. In this year, it is ready to launch a model with only half the price, but the price of 75,000 yuan. It is also unbearable for the average family. Samsung's latest F10M has not yet finalized the price, but its price will be much higher than traditional projector products. Therefore, the price also determines whether the LED light source projector can be quickly popularized.
Consumer: Low cost of use as an alternative to TV
From the user's point of view, the LED light source is an excellent choice for the projector to become a mass consumer product. Through the author's interviews with some consumers, people often hear some concerns about the cost of the projector.
The problem of traditional projector lamp life has been the biggest bottleneck in its development many years ago. At present, the life of a conventional projector is 3000-4000 hours, and the price of a light bulb is as high as 1000-2000 yuan. Although the current price of some entertainment projectors has dropped to about 3,000 yuan, the cost of replacing the bulbs after one or two years of use has discouraged many consumers.
Not only that, in the article of our Zhongguancun online projector channel, the feasibility of replacing the TV with the projector has also been analyzed from many angles, and the problem of the later cost has become the most important reason why the projector can not replace the TV. In the past, ultra-portable LED light source projectors have lower brightness, generally 200 lumens, and it is difficult to compare with TV in a bright living room environment.
Samsung's LED light source projector with a brightness of 1000 lumens completely solves this problem. The battery life of up to 30,000 hours solves the problem of post-use cost, allowing users to use it like a TV for a long time without worrying about lamp life. . At the same time, the brightness of up to 1000 lumens, even higher than the brightness of some high-end cinema projectors, is completely problem-free in a bright living room environment.
Samsung's latest release of 1000 lumens LED light source projector, the industry for its attention, this product also surpasses the traditional polymer machine bottleneck in many technologies. In this paper, the author analyzes the impact of high-brightness LED light source projectors on the traditional projector industry from the aspects of technology, industry and consumer demand, which will also make the projector industry change in the future. For consumers, high-brightness LED light source projectors can easily project more than 100 大 large screens without worrying about the cost of later use, which will have a significant impact on the future home appliance market.
