What is SMD LED and High Power LED? What are the benefits?

SMD LED stands for surface mount LED. Specifically, it’s a light-emitting diode that is mounted onto and soldered onto a circuit board. An SMD LED is quite small since it has no leads or surrounding packaging that comes with a standard LED. This means it’s best handled, not by a human, but by automated assembly equipment. An SMD LED also has a wide viewing angle, thanks to the fact that it does not have the standard LED’s epoxy enclosure that focuses the beam.

Benefits of SMD LED

The SMD LED gives off very little heat. It also has a low voltage and current requirements. Like a standard light emitting diode, a surface mount LED gives off almost no heat. It also typically has similar low voltage and low current requirements. They are commonly used to indicate device status on computer motherboards, routers, hard drives, USB flash drives and any other application where physical space is at a premium. Computer motherboards, hard drives, routers, flash drives and other applications where there’s no room for larger technology are also common uses.

Others include LCD display backlighting, keyboard lights, and pushbuttons. They’ve also been used for instrument panels in aircrafts. A few manufacturers have created an SMD LED lighting solution by combining it with a resistor, small circuit board, lens and cable to provide and bright, cool LED light that runs on just 12 volts, and which is tiny enough to be mounted almost anywhere, (for instance, to light a cup holder).

There are other, large-scale applications, too. For instance, they are used for indoor display screens. SMD LEDs work well because you can arrange a large number of diodes in tight groups of red, blue and green, generating a large variety of colors. This screen technology, which is now found in stores and malls, is now also popping up in large outdoor displays. More information, please come to lighting wiki here.

SMD LED gives high brightness while it has lower power consumption than of a normal LED light tubes (e.g. dip or cluster led) and traditional light bulbs.  See its features below:


Small Size: SMD LED light source is a very small and light chips enveloped by epoxy resin.

Low Power Consumption: Generally, the voltage per SMD LED is 2-3.6V, current 0.02A-0.03A. It uses very low voltage and current. Power consumption is very low, just equals to 1/8 of incandescent light, 1/4 of traditional light.

Long Life Span: Under proper current and voltage condition, the life span of SMD LED can reach 100,000 hrs.  Compared with the other LED tubes(like Dip LED),the optical decay reduce from 10% to 5% in 1000hrs. Produced by Automatic equipment, via heat emitting technical process, the life span of SMD LED is longer.

High Brightness: Mainly adopted 3528 and 5050 SMD high brightness chip, single SMD LED over 5.5lm/1800MCD.

As above, we have mentioned about SMD 3528 and 5050.  What do they mean and what is the difference between the two?  Let’s see the following:

SMD 3528

consists of one light-emitting chip

dimension of chip : 35 x 28 mm

power: 0.08W/ pearl

SMD 5050

consists of three light-emitting chips

dimension of chip : 50 x 50 mm

power: 0.24W/pearl

Theoretically, SMD5050 is 3 times brighter than SMD3528.

High power light-emitting diodes (LEDs) use from 500 milliwatts to as much as 500 watts in a single package (as per 2012 Q1, only Optogan, Germany has developed a single LED module which can be operated up to 500 watt). Most of the electricity in an LED becomes heat rather than light (about 70% heat and 30% light). If this heat is not removed, the LEDs run at high temperatures, which not only lowers their efficiency, but also makes the LED less reliable. Thus, thermal management of high power LEDs is a crucial area of research and development. It is highly necessary to keep the junction temperature below 120°C to run the LED’s for maximum lifetime.

High-powered LED lights are commonly used in horticultural circles to help in the growing and cultivating of certain plants. In particular, higher-powered LED lights can ensure that sunlight–although artificial–can reach these plants in the winter months and even at night. These artificial light cycles can also trigger specific growth and flowering. Test your high-powered LED light by plugging the power cable into a wall-socket and looking for any obvious signs of light and heat.

Our factory mainly use High Power LED chip course which is the best match for LED car light,the High power chip is highest price and brightest led product’ lighting sources, the price is also geat different!

We have our own led car light factory and profession technology,now we have a large number of stable customers from different countries.If you want to build business relationship with us,we will can give you some suggestions to help you to choose the product markets,If you want to develop other marks,we also can share our experience with you.
