Lumens And ANSI Lumens In Projector
By XGIMI Tech - 2022-01
Previously, people determine a bulb's brightness with watts. But in recent times, the lumen is widely used to measure the brightness of light bulbs. Later, as projectors become more and more popular, ANSI lumen occurs. Both lumen and ANSI lumen determine the level of brightness you want or are available.
In this article, you'll learn what are lumen and ANSI lumen, and how many ANSI lumens you'll need for your projector.
What Are Lumens And ANSI Lumens
A lumen is a standard unit of luminous flux (also known as brightness) used in physics to describe the luminous flux of a light source. The lumen may be thought of as a measure of the total quantity of visible light emitted from a source in a particular beam or angle. Simply put, lumens are the unit of measurement that shows how strong or intense a light source is.
The ANSI American National Standards Institute (ANSI) lumen is often used to evaluate projector brightness. ANSI lumens are measured using smarter methods that involve many variables. While the measurements are actually much more complicated, you will find that the ANSI Lumens Measurement Method has several elements that help provide a more accurate value.
Lumens And ANSI Lumens Measurement
The mortal eye is sensitive to three wavelength ranges of light, each corresponding to the peak event of retinal photopsin colors red (R 560 nm), green (G 530 nm), and blue (B 430 nm). This is the base for RGB- grounded color videotape systems.
Consider putting the light 0.30 measures down from a flat wall on which we will draw a 0.09 cadence forecourt, this surface emits one lumen per square bottom of illumination.
The equation between ANSI lumens and Lumens: LED Lumens value / 2.4=ANSI lumens.
XGIMI's projectors use ANSI lumens.
Why Are Lumens important?
Without enough light output, a projector can't display brilliant pictures. Images will appear muddy and fuzzy if the light output is too low, even if you decrease the lights in the room to compensate.
Look for the ANSI (American National Standards Institute) Lumen rating on a projector's light to see whether it has the necessary brightness for your needs. It will inform you of the maximum amount of light the projector is capable of producing. Projectors with 1,000 ANSI lumens or more are generally appropriate, although other considerations such as ambient light, screen distance or size, and room size will also influence whether less or more lumens are required.
Factors affecting ANSI Lumens in Projector
ANSI Lumens is a standard measurement of projector brightness, which determines how bright the image will appear on the screen. This measurement is determined by the American National Standards Institute (ANSI), which specifies the brightness level of a projector based on a specific test pattern. The brightness level is calculated by taking the average of nine different measurement points on the screen. There are several factors that affect ANSI Lumens in a projector, including:
1. Lamp brightness: The brightness of the projector lamp is one of the most critical factors that affect ANSI Lumens. The brighter the lamp, the higher the ANSI Lumens. Most projector manufacturers specify the lamp brightness in their product specifications.
2. Projector optics: The optical design of the projector also affects ANSI Lumens. The quality of the lens, the size of the lens, and the number of lenses in the projector all have an impact on the brightness of the image. A high-quality lens will produce a brighter image than a lower quality lens.
3. Screen size and distance: The size of the screen and the distance between the projector and the screen also affect ANSI Lumens. The larger the screen size, the more ANSI Lumens are needed to produce a bright image. Similarly, the farther the projector is from the screen, the more ANSI Lumens are needed to produce a bright image.
4. Ambient light: The amount of ambient light in the room also affects ANSI Lumens. The brighter the room, the more ANSI Lumens are needed to produce a bright image. If the room is too bright, it can wash out the image, making it difficult to see.
5. Color and contrast: The color and contrast of the image also affect ANSI Lumens. Brighter colors and higher contrast images require more ANSI Lumens to produce a bright image.
In conclusion, ANSI Lumens is an essential measurement in projectors that determines how bright the image will appear on the screen. The factors mentioned above, including lamp brightness, projector optics, screen size and distance, ambient light, and color and contrast, all have an impact on ANSI Lumens. Therefore, it's crucial to consider these factors when selecting a projector for your needs.
How Many Lumens/ANSI Lumens Are Needed For An Indoor And Outdoor Project?
When determining how many ANSI lumens to utilize, there are three factors to consider, namely:
• Ambient Light
• Screen Size
Locations: Decide where you would like to use your projector. Outdoor projectors often have lower brightness when compared to home projectors. That's because higher brightness generates more heat, and a larger space for dissipating the heat will be needed, thus making it less portable for a projector.
Ambient Lighting: Ambient light is really one of the most important considerations when purchasing a projector. The amount of natural light entering the room where the projector will be used is called ambient light.
Low Ambient Light Environments: If you'll be using your projector in a dark room or one with low ambient light, any ANSI lumens rating will suffice. You might choose projectors with low ANSI lumen ratings if you can manage the ambient light in your room using window coverings or by turning off artificial light sources. In low ambient light conditions, projectors with 300 to 600 ANSI lumen ratings will suffice.
Low to Medium Ambient Light Situations: People installing projectors in medium ambient light environments will require models with a greater brightness rating than those listed above. Depending on additional criteria, such as the size of the projected images and the distance between the projection screen and the projector, the brightness of these projectors can range from 600 to 2,000 ANSI lumens.
Medium to High Ambient Light Environments: To project viewable imagery in areas such as auditoriums, public venues, or workplaces with glass windows without shades, projectors with high brightness are required. These areas have a lot of ambient light, thus a projector with a strong light source that can counterbalance the influence of said ambient light is required. For strong ambient light environments, a projector with at least 2,000 ANSI lumens rating may be necessary.
Screen Size: The larger the screen is, the higher the brightness needed. If you prefer a large screen size, ie. 200", it's definitely recommended to get a projector with higher ANSI lumens.
To learn more about the number of lumens/ANSI lumens required for a project. The table chart below is some advice for choosing the suitable ANSI lumens for your projector:
|Ambient Light||ANSI Lumens|
|Indoor low ambient light||300-600 ANSI lumens|
|Indoor medium ambient light||600-1600 ANSI lumens|
|Indoor high ambient light||1600-2500 ANSI lumens|
|Outdoor low ambient light (ex. camping in dark woods)||200-500 ANSI lumens|
|Outdoor medium ambient light (ex. backyard with some street lights)||600-1000 ANSI lumens|
|Outdoor high ambient light (ex. midday with sunlight)||>1000 ANSI lumens|
