How to choose right?

Viewing Distance

The distance between your led clock and its viewers is the most important factor in determining the types of LED sign you need. Longer distances require less resolution, and shorter distances require higher resolutions. If you are standing 60 feet away from a led sign, the letters need be about our Godrelish 2 inches to be legible; If you are standing 180 feet away from a led sign, the letters need be about our godrelish led 6 inches to be legible. The rule is that you need 1 inch for every 30 feet of viewing distance.

Brightness

When purchasing an outdoor-bright LED sign, it is important to understand that there are major differences between LED sign systems. our godrelish an outdoor-bright sign must have at least 5000 NITS of brightness to be seen in the daylight sun.godrelish led signs typically exceed this standard by a long shot. Contrast ration is another important factor in overall brightness, and refers to the difference between levels of blacks compared to the level of whites in the sign, Things like reflective surfaces, glare from the sun, and dimming all affect contrast ratio.Our godrelish LED sign meet the international standard, 10/1. To optimize the contrast ratio and overall brightness, features a unique louver system to shade each individual diode from the glare of the sun. The louvers were computer modeled to optimize the view from onlookers below while blocking the maximum amount of sun from all sides. No other system on the market offers this unique, individual diode shading. Together with the high-density array

Viewing Angles

Diodes are capable of outputting light at a variety of angles. Diodes can put out a single, narrow beam of light like a flashlight, or they can output a wide array across a room like a light bulb. Diodes output about the same amount of light no matter what type they are-but the “high-beam” diodes with a narrow angle focus more light into one small spot, whereas the “wide angle’ diodes spread their light across the horizon. So, if you were to stand in front of a sign made from “high-beam” diodes with narrow viewing angles, you would see an extremely bright led sign if you stood directly in front of it, but the minute you walked away from the small spot light of it’s focus, you would see nothing but black. On the other hand, if you were to build a led sign with lots of “wide angle” diodes, you could move around and to the side of led sign, and still see a great image. Godrelish led signs use wide viewing angle diodes,with super wide viewing angles up to 140 degrees. Together with the high density of diodes, our godrelish led signs are both bright and have wide viewing angles at the same time.
