In general, the cooler the environment, the higher an LED's light output will be. Higher temperatures generally reduce light output. In warmer environments and at higher currents, the temperature of the semiconducting element increases. The light output of an LED for a constant current varies as a function of its junction temperature. Figure 9 shows the light output of several LEDs as a function of junction temperature. The temperature dependence is much less for InGaN LEDs (e.g., blue, green, white) than for AlGaInP LEDs (e.g., red and yellow).

Any businesses or organizations with access to vehicle or pedestrian traffic can use LED signs to promote events and products, and increase their interaction with consumers. Many already invest in more traditional advertising to reach potential customers. Advertising with an LED sign is less expensive, and more responsive and flexible.

The sign is programmed with software that allows the user to create, schedule and update messages. The sign owner can choose and arrange text and images for each sign message. Once created, messages, also referred to as content, can be scheduled and updated right away, or can be pre-scheduled weeks or months in advance.

Many businesses struggle to get results from traditional advertising media like newspaper, radio and television. An outdoor digital sign offers the most cost-effective tool for delivering vibrant, eye-catching advertising to customers.
We will help you make the right decision through our 10 steps:

Pixel Pitch measures the distance between each cluster of LED diodes. The closer the spacing, the tighter the resolution and the higher the image quality. Highly detailed product photos viewed up-close by pedestrians or slow-moving traffic work best at a higher resolution. Signs installed farther from traffic or higher above grade can be a lower resolution.

You are very lucky to read this article if you need very high brightness LED billboard. Nowadays in LED display industry, most of outdoor led displays are made by SMD technology, it is produced by the machine, better color uniformity to show the videos and images than DIP. But why there are still some customers are fall in love with Outdoor DIP technology? There are some of our researches as below.

An LED (light emitting diode) is an efficient, effective and ultrabright alternative to incandescent light bulbs. Unlike traditional bulbs, LEDs do not burn out, instead they dim slowly over a longer period of time, typically lasting 100,000 hours, or over 11 years.
