Combination of laser and LED projection industry innovation again - Projector - Education Industry

After years of development, Projector Walk today Technology Each passing day, but still there are many technical bottlenecks. As Projection Traditional machine Light source Factors, both brightness and color or power consumption and other aspects, has been unable to reach a higher altitude, therefore, solid-state lighting revolution has arrived.

Solid state light source is a revolution in lighting technology, is a development by leaps and bounds, but also future trends. Recently the LED light source and the extremely strong partner with a laser light source, in today's projector industry is deeply significant, it should be said LED light source and laser source as the two solid-state light source Technology Each has its own advantages and applications, LED light source can be Projector Sizes smaller, more Environmental protection . However, LED products have their limitations. For example, in Projector The most important Technology Index Brightness Output, luminous flux, the current widespread use of LED lighting products that are not high, and therefore limits the range of applications, only suitable for use in small scenes.

Laser light source as the crystal / semiconductor structure of the high points of cold light source, the color purity, luminous efficiency, luminous efficiency, long life, low attenuation and low power consumption, low heat, high security and other aspects much better than the xenon light source, only constrained by the current high cost of a larger one-off capital investment, has not yet been widely used.

LED compared to traditional light sources, which has been characterized by small size, much smaller than our common Projector Are often used UHP light source or light or metal halide light source UHE, even made Projector Light source, is still much smaller. This is also the use of LED light projection product usually leaves us with a small, portable, mini and so the main reason.

The same time, LED light is cold light source, such as in the work does not produce as high-energy metal halide lamp, the lamp module and cooling systems can significantly reduce compared to the original, coupled with relatively simple optical structure design, not only reduce its volume, but also simplifies the internal structure of the product. Projection products using traditional light bulb is turned on will take some warm-up time, thermal shutdown power to continue for some time; the LED does not require preheating time and power can do that is light, but after having to wait for cooling power, so use LED light source Projector Products which means that the light can do that off Jimie, giving the user brings great convenience.

On Projector Have some understanding friends know Projector Bulb is a Consumables , And Printer The cartridge is similar with the use of replacement needs, and often their life and the price is not proportional. That is, no matter how much money you spend the Projector In the use of 2000-3000 hours, you have to change Projector Light bulb for, and pay a lot of money costs. The LED life of up to thousands of hours, some even more than 100,000 hours. Meanwhile, LED light source than the traditional cost to be much lower. According to insiders, with LED light source produced Projector Bulb 1 Lumen Costs less than one yuan, not only reduced lighting costs, as savings in cooling system, to streamline the optical structure, the total cost can be well controlled, and even light users need to be replaced, no need for this excessive spending . It can be said with LED light source, whether front-or post-maintenance, that the user can save a small fortune in costs.

Have to mention is that both the traditional light bulbs contain harmful mercury, although its content is very low, but still more or less harm to the human body; the LED light source will not contain any harmful elements, from this point of view, LED is the real environmental protection.

Although the LED as Projector Light the many advantages, but it also has obvious flaws. Brightness Is plagued LED Projector One of the biggest problems spread. Although the market has Brightness Up to 1000 Lumen The LED above Projector Products, but this Brightness For everyday use, particularly for business applications are far from adequate; and even Brightness Relatively low LCD Projector Its usually easy to break 2000 Lumen Compared to the LED light source, clearly advantages to much more.

Two new light source for a time became the focus of the projection industry, manufacturers have also usher in a new industry is the era of struggle, but at this time Casio has subvert the traditional, to create a leap of more products.

Not long ago, the show at the CES, Casio once again fantastic and the launch of the world's first mercury-free high Brightness Projector , And these new products is the first time with a mixed source.

Currently, high-pressure mercury lamp is 2000 Lumen Above Brightness Projector The main light source, in order to reduce the environmental impact of high-pressure mercury lamp, Casio laser Technology And the LED light source Technology Mixed for DLP Projector R & D and manufacturing, and ultimately 2000-3000 Lumen High Brightness .

This mixed light source is an absolutely innovative Technology , Up to 20,000 hours of their life, and effectively solve the LED light source can not provide high Brightness The output of the problem.

Combination of two new light sources, can be the perfect blend of the advantages of both, which we knew nothing, but at least you can see, now the darling of the largest light projection?? LED light source, its largest disadvantage has been reversed, and the life of its greatest strengths is also, as started for, these two points alone, we have to look forward to its real published.
