Analysis of the four core advantages of LED light source DLP splicing unit

As a new large-screen video technology, LED light source DLP splicing products have always been one of the key industrial innovations that the industry pays attention to. The use of next-generation light source LED technology is not only a simple change in light source technology, but will also fundamentally change the practical performance of DLP splicing products and even create many new application modes. So, what unexpected new surprises will the new LED light source DLP splicing products bring to industry customers?

Lower system cost of ownership

The first significant change brought about by the application of LED light source to DLP splicing wall products is the significant reduction in user costs. Although the use of LED technology will increase the initial investment of DLP splicing wall projects by 30%, the life of LED light source reaches 60,000 hours, which is about 20 times that of traditional mercury lamps. In other words, customers will save at least 20 bulb replacement costs during the life of the DLP splicing wall. This cost is not only enough to offset the increase in the cost of DLP splicing units caused by LED technology, but also can "save a considerable amount of investment".

Another feature of LED light source technology is that the three primary colors emit light independently. This makes the DLP projection system no longer need the previous color wheel spectrometer. As a mechanical operation product, the maintenance and replacement frequency of the color wheel is also an important part of the customer's cost. Although the color wheel component is not the core consumable of the DLP splicing wall, the economic benefits of LED light source products without color wheels cannot be ignored.

The long-life LED light source also greatly reduces the maintenance frequency of DLP splicing walls. The annual maintenance quantity can be reduced by at least 50%. This will also serve as an important "money-saving" node and become one of the important added values ​​for customers to purchase LED light source products. In addition, as a highly efficient light source product, LED will also bring higher luminous efficiency and higher light utilization, thus reflecting another "low-cost" characteristic of saving electricity.

Higher system reliability

LED light source products are solid-state cold light source products. They have high working efficiency, low heat generation, and are less likely to be damaged accidentally in a solid state. Traditional mercury lamp light sources are as fragile as ordinary light bulbs. When working at high brightness, the product temperature is extremely high and it is more likely to be damaged, burned or exploded due to accidents. The solid-state luminescence characteristics of LED light sources significantly increase the stability of the light source itself.

Unlike traditional mercury lamp products, LED light sources are driven by low-voltage DC pulses. The power supply does not contain high-voltage and high- current components, so the power supply life and stability are more controllable. Combined with the natural light emission of the three primary colors of the LED light source, there is no need for mechanical color wheel components to split the light, making the LED light source part more stable than traditional mercury lamps in terms of power supply, control and splitting.

[page]The LED light source has the characteristic of independently emitting the three primary colors, so even if a "bulb" fails, the whole machine can still display the picture in a colorless state. This is in stark contrast to the situation that the traditional single-lamp DLP splicing unit cannot work once the bulb burns out. The characteristic of being able to display in a colorless state means that if the light source fails unexpectedly, the LED light source can minimize the loss to the customer to the greatest extent, or even eliminate it. Compared with the simple single-lamp DLP splicing unit, the reliability of LED light source products is closer to that of a dual-lamp backup system.

Green, environmentally friendly and low carbon

LED light source technology is a well-known green environmental protection technology. Its semiconductor process characteristics make it easier to control toxic metals, unlike traditional mercury lamps, which are likely to leak toxic elements inside the mercury lamp once damaged. As a semiconductor component, LED light sources can also be recycled and reused, and the important metal elements can be recycled and reused in the smelting process.

In addition, LED light source products are also light source products with high luminous efficiency.

Under the same brightness conditions, it has lower energy consumption. In addition, LED light sources use digital pulses to emit light, and the three primary colors are independent. Only when the DLP light valve chip DMD needs a certain color of light, the LED light source will work. This is completely different from the continuous ignition working mode of traditional mercury lamps. The characteristics of LED light sources that do not work continuously and only emit valuable light when needed also enable them to better meet the needs of future economic development for low-carbon and environmental protection.

Bright colors and more vivid pictures

LED light source is a typical wide color gamut light source, and its color effect far exceeds that of traditional mercury lamp products. At the same time, the feature of not requiring additional filtering by the color wheel can also ensure that the entire DLP optical system can accurately restore excellent colors. Juyang LED light source DLP splicing products also have 100% EBU color gamut, reaching European broadcast standards. At the same time, with the independent adjustment technology of the seven primary colors of R, G, B, C, M, Y, and W, various mixed colors and detailed colors are more realistic and gorgeous.

Another feature of LED light source is that the fully digital working mode allows the LED light source DLP splicing product to turn off all light sources when projecting black images, and turn off all blue and green light sources when projecting red images... This feature makes the color adjustment of the product more accurate, especially the contrast and layer depth performance have been greatly improved.
