When purchasing a projection product, brightness is always a core indicator. The higher the brightness, the better the display effect will be under the influence of the same ambient light. The brightness of many smart projections now exceeds 1000 ANSI lumens, which is nothing compared to traditional **lamp projections. For miniature projections, this is already the current top brightness configuration.

About several brightness concepts of the projector
ANSI lumens: Lumen is a unit that measures the brightness of a projector and refers to the amount of light emitted from the projector; ANSI lumens is a measure of the projector's luminous flux set by the American National Standards Institute. The specific methods are: (1) The distance between the projector and the screen is 2.4 meters; (2) The screen is 60 inches; (3) Measure the illuminance at each of the nine cross points of the screen “Tian†shape with an illuminance meter, and seek The average illumination of 9 points is obtained; (4) The average illumination multiplied by the projected screen area is ANSI lumens.
ANSI lumens 9-point test
ISO lumens: ISO is not unfamiliar to everyone. This is the International Organization for Standardization. It has detailed testing standards for brightness detection.
The ANSI standard was used in many projectors in the early days as well as in European and American manufacturers. The ISO standard is now increasingly used in Japanese manufacturers and new machines.
Where are the micro-projection brightness bottlenecks?
The volume of traditional projectors is generally very large, and the high-voltage lamps inside them have high brightness, large power consumption, and high heat generation, but they also need to reserve enough space for heat dissipation and hang on the top of the house.
At present, the basic micro-projection is LED light source, compared to the brightness of the light bulb is not dominant, and because the LED light emitting unit is dispersed, affecting the LED light source concentration, which makes the LED light source of the micro-projection products in ensuring the brightness Under the premise, smaller body sizes cannot be achieved. It can be clearly seen that, with the brightness of micro-projections ranging from dozens of lumens to the current thousands of lumens, its volume is also increasing.
The other is the microchip used in the chip, most of the micro-projection products used by the DMD chip is Texas Instruments (TI) specifically designed small-scale products, ranging from 0.2 inches to 0.47 inches, can clearly see the four chips from the above figure Specifications. The size of the chip not only limits the resolution but also affects the brightness.
The 0.45-inch chip is currently the mainstream of high-end micro-projection, with a resolution of 1280×800. Many micro-projections with more than 1,000 ANSI lumens at a price of 3,000 yuan are all based on this chip. The 0.47-inch and 0.45-inch chips have the same typical brightness, but it is the only chip currently used for micro-projection resolution of 1080P.
What is the performance of ultra-luxury brightness?
For the micro-projection product F1 just released by the micro-whale some time ago, it uses a 0.45-inch DMD chip and has a brightness of 1200 ANSI lumens. When viewed during the day (sunshine is not direct), the overall brightness is sufficient, and it is not necessary to shave it. .

Although the brightness of micro-projection is already high enough, there is not much problem in the daytime, but if you want to achieve better viewing results, you must certainly do a basic shading work. In the bright light environment, 200 ANSI lumens and 1000 ANSI lumens are also effective. There is not much difference, but in the low-light environment, the advantages brought by higher brightness are obvious.
