Another major factor for choosing an LED projector is that its engineering supports a more compact design than traditional projectors, with smaller form factors that allow some LED projectors to be portable. This is further complemented by the fact that LED lights are less susceptible to the effects of environmental factors (such as dust) than traditional bulbs and also do not emit heat so that cooling is not a factor. When combined, these three factors make the technology behind LED projectors ideal for designing portable projectors for outdoor use.

Bright-field microscopy

In our time, movies have become a necessary staple of life. Given this, how to get the most precise and accurate colors out of our audio-video equipment has become a question of growing importance. With all this in mind, what exactly is color accuracy? Is color accuracy just a wide color gamut? And finally, how to we achieve color accuracy?

In terms of the quality of LED projectors, the color range of the LED lights used in LED projectors tend to cover, if not eclipse, the entire REC. 709 color gamut used in high-definition video. This means purer, more saturated colors with greater color contrast when compared to the lamps used in traditional projectors, making LED projectors ideal for watching Blu-Ray movies or playing video games with artificially vivid colors.

For our LED projectors in general, BenQ offers an auto color calibration feature that allows for more consistent color during the inevitable decay of the LEDs over the course of the projector’s lifespan. Normally as projector use continues, the LED lights in the projector tend to deteriorate unevenly so that one light (usually the red LED) might deteriorate far more rapidly than the others, causing a greenish-blue tint to the resulting image. BenQ’s auto color calibration prevents this phenomenon by adjusting the other LEDs accordingly, ensuring a consistency in color throughout the lifespan of the projector.

True colors evoke feelings of sorrow, joy, romance and thrills by preserving the original image. BenQ home cinema projectors embody our belief to “Convey the truest color and impart the deepest feelings to the viewer.”

An additional plus to using an LED projector is due to its use of LED lights that there is no warm-up period when turning on an LED projector. Instead the video is able to be shown at its set brightness.

Like all other industries that deal with lighting, the projector industry has spent the last decade embracing the use of LEDs in their products in order to take full advantage of the benefits that the now widespread technology offers. Yet while some consumers are just now getting introduced to projectors that use LED lights, the industry itself is already taking the next step in improving upon the design of LED projectors with the release of 4LED projectors. But what exactly are 4LED projectors?

This document provides information about bright field microscopes. It describes how bright field microscopes work by using light to illuminate specimens on a slide, which appear dark against a bright background. It outlines the basic components of a microscope like the stage, objectives, and eyepieces. The document discusses using bright field microscopy to view stained specimens and provides tips for microscope care, setup, use, and troubleshooting common problems.Read less

Simply put LED projectors are projectors whose light sources are LED lights assembled on chips. Whereas traditional projectors use a single incandescent bulb as their light source whose light is then passed through a colour wheel to produce its primary colours, LED projectors use individual lights for each primary colour. The most common type of LED projector on the market that uses this type of design is the 3LED projector, which we will discuss later.

Given all of this, what makes BenQ’s 4LED projectors stand out from the crowd? Beyond the benefits of LED technology discussed above, BenQ offers a slate of features which help optimize the LED projector viewing experience.

As mentioned above, the majority of LED projectors on the market are what we call 3LED projectors. 3LED projectors are projectors whose light sources are individual LED lights for each of the three primary colors in the RGB color system: red, green, and blue. These lights then combine in some variation to construct all the colors in an image and are then directed towards the projector lens. The development of 4LED projectors is directly related to this concept as it is the next step in LED projector technology meant to improve upon the brightness and color saturation of the 3LED design.

By definition 4LED projectors are LED projectors that add an additional “pump” LED to the 3LED ecosystem whose light is also to amplify the overall output of green light. By adding this separate light, the output of light increase in overall brightness when compared to a 3LED projector. This type of design also helps keep the surface area of the original three LEDs unchanged thereby avoiding both the need to significantly increase the projector size to accommodate larger LEDs and the additional heating that would be produced by those LEDs which would otherwise affect the LED’s lifespan.

Knowing what distinguishes LED projectors from traditional projectors, what are the benefits of using an LED projector? Some of the main benefits of using an LED projector are the same one’s users of household light bulbs are familiar with: their outstanding lifespan and energy efficiency. On average, an LED projector provides up to 20,000 hours of use under normal settings while hitting up to 30,000 hours of use if projecting under energy-saving modes. This is almost 10 to 15 times the lifespan of a traditional projector’s lamp, helping LED projectors avoid the maintenance costs associated with lamp replacement.
