A comparison between OLD "DIP" leds and NEW "SMT" leds.
SMD leds are the leading technology for LED Displays, now whether it is for indoor or outdoor LED Display/EMC Displays. Check with your manufacturer see if they are still using the old DIP technology or if they have adopted the new technology. In the past, the rule of thumb has been for outdoor LED Displays use DIPS / indoor LED displays use SMD leds, however that has now changed due to improved technology.
DIP LED stands for Dual In-line Package. These leds got their start being used in different technology since the early 1960’s, and are now being used in just about every lighting situation pertaining to technology. SMD stands for Surface-Mount Device, and it is also known as SMT Surface Mounted Technology. As in almost all evolution, SMD leds came about due to devices becoming smaller and the need to be able to have this type of LED fit within the smaller technology. So with that being said, the uses for SMDs have rapidly increased in the first decade of the 21st century. SMD chips allow for improved quality control and offer a product that features better heat dispersion, high lumen output (high lumen flux ) and longer overall life (low optical decay) than its predecessor the DIP LED
Why should we use SMT LEDS over DIP LEDS.
SMDs are light weight.
Have a much wider visual angle which is 140° by 140°.
Color output is much crisper and truer to the intended color along with better color uniformity.
More energy efficient then the DIP (use up to 10 times less power than DIP leds in many cases).
SMDs have a much more natural look and feel of an image on an LED Display being much less pixilated.
