How To Select A Best Outdoor LED Displays?


You must consider below factors before buy an outdoor LED displays.

-Display installed outdoors, often sun and rain, wind and dust cover, poor working conditions. Electronic devices are wet or damp can cause serious short circuit or even a fire, causing failure or fire, resulting in losses;

-The display may be caused by the strong electric magnetic lightning attacks;

-The ambient temperature varies greatly. Display work itself must produce some heat, if the ambient temperature is too high heat and poor, IC may not work properly, or even burned, so that the display system does not work;

-Wide audience, sight distance requirements far, wide vision requirements; ambient light changes, in particular, may be subject to direct sunlight.

Therefore, the LED screen have to meet the following requirements;

1. The housing of Screen must be strictly waterproof; Screen body have good drainage measures in the event of a smooth water discharge;

2. In the display and buildings to install lighting protection devices, Display main body and cover a good grounding, grounding resistance is less than 3 ohms, so that large currents caused by lightning discharge;

3. Install ventilation cooling, so that the internal temperature of the screen body -10 ~ 40 between. Screen behind the top of the installed fan, exhaust heat;

4.Selection of the operating temperature between -40 ~ 80 , industrial-grade IC chip to prevent winter temperature is too low so that the display can not be started. ;

5.In order to ensure a strong ambient light visible case of long-distance, you must use high brightness light-emitting diodes;

6.Display media use the new wide angle tube, wide viewing angle, color pure, coherent and coordinated, life of more than 10 million hours. The outer display media packaging for the cover along with the most popular square tube, silicone seals, no metal assembly; their exquisite appearance, durable, with anti-sunlight, dust, waterproof, anti-high temperature, anti-short circuit.

Why people like LED time and temperature display so much?


A digital clock is a type of clock that displays time and temperature digitally. Among the many digital clocks, the most representative digital clocks should be LED digital clock which uses seven-segment LED (light-emitting diodes).Seven-segment LED displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying numerical information. It is available for Interior and Exterior use, provides a modern and precise way of displaying time and temperature, and is suitable for a wide range of applications from the most demanding of areas to the most prestigious of locations.

Here are some instructions that may help you to understand why people LED like LED time and temperature display.

1, Easy to operate:

Some people find difficulty in setting the time in some designs of digital clocks being some designs make more functions on the buttons. On the contrary, time and temperature sign only have four buttons to set time, temperature, date etc so it is very easy to operate.

2, Attractive looking:

For interior use, the case is made of black aluminum which resists dust. For exterior use, the case is made of black iron which resists water and dust.

3, Multi-FunctionsThe main function is to display time and temperature. For time, as you know, there are two timing formats. One is 24 hours format; the other is 12 hours format (Use in the United States and a few of other countries).If you require, it can work both in 12 hours and 24 hours. For temperature, there are two temperature formats; One is Celsius; the other is Fahrenheit. So you should confirm which temperature you want before you buy. What is more, it is also available add extra functions such as countdown and count-up, date, etc.

4Other factors:

Size optional: Indoor digit height options: 1.8”, 2.3”, 3’’, 4”, 8”;

Semi-outdoor and Outdoor digit height options: 5”, 6’’, 8”, 10’’, 12”, 16”, 18”, 24”, 27”, 36” Etc.

Color optional: Red, Yellow (Amber), Green, Blue, White Etc.

Time format optional: HH:MM, MM:SS, HH:MM:SS Etc.

A guide to LED countdown timer/LED digital clocks

LED countdown timer is most for commercial usage. This article is brief introducing the feature and function of the LED countdown timer.

A LED countdown timer is one types of LED digital clocks which makes of seven-segment LED (light-emitting diodes) or dot-matrix display.

2, Count-up: As you activate “count-up”, timer will start to count-up. Once the countdown reaches to 99:59(MM:SS) or 99:59:59(HH:MM:SS). The inner buzzer will sound about five seconds, and then it stops automatically.

3, Reset: There are two reset optional. One is reset to 00:00 or 00:00:00; the other is reset to preset time. Press “Reset”, the timer stop countdown or count-up. And then reset to 00:00 or 00:00:00 or preset time.
