What are the Basics of LED Lighting? 

13 Dec 2019

LED is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. They do a lot of different jobs and are suitable for many LED lighting applications. Besides, they form numbers on digital clocks(SMD), transmit information from remote controls, light up watches and tell you when your appliances are turned on. When they are collected, they can form images on an advertising display board or illuminate a traffic light. 

What is an LED?
An LED is a type of diode that turns electrical energy into light. A diode is an electrical component that only works in one direction. An LED is an electrical component that emits light when electricity flows through in one direction, from the Anode (positive side) to the Cathode (negative side).

LED Types
In general, 5mm Oval LED and surface mount LED chip are the main types. 

A. 5mm Oval LEDs


5mm Oval LEDs are diodes inside a 5mm diameter lens with two thin metal legs on the bottom. They are used in broad applications where a lower amount of light is required, such as commercial lighting, architectural lighting, LCD TV/monitor backlights, etc. It runs at a much smaller drive current max. 30mA, while the surface mount LED chip requires at least 350mA. Zhongshan Goodchip Lighting specializes in producing all kinds of high-grade LEDs. All Oval LEDs are available in sizes of 3mm, 5mm and different colors. OEM orders are welcomed. 
B. Surface Mount LEDs (SMD)

Surface Mount LEDs are diode(s) that can be placed on a circuit board with a silicon dome over the diode to protect it. It is a high power LED lights. With no wires, these devices provide less fuss and with seamless application. Instead, SMDs have tiny metallic contacts that can be directly soldered to circuit boards. Goodchip's LEDs are energy efficient and provide a superior lighting experience. With a vast selection, class A quality, high reliability, the prolonged lifespan of up to 30,000 to 50,000 hours and excellent performance of waterproof, dustproof and UV-proof, Goodchip's SMD LEDs are sure to meet the specifications of your application. Our SMD LED product offering is most commonly used for the landscape lighting industry, plant grow light and more.
We have to say, though LEDs are in small form, they produce massive light while maintaining fantastic efficiency. LEDs are the unsung hero in the electronics world. They have the advantages listed as followed:


 1. Low voltage and current to drive the LED.
Voltage range – 1 to 2 volts. Current – 5 to 20 milliamperes.
2. High intensity, good consistency, low decay 
3. Fast response time – only about 10 nanoseconds without any heating or warmup time
4. Miniature in size and therefore lightweight.
5. Have a rugged construction and hence can withstand shock and vibrations.
6. Long lifespan of 30000-50000hours.  

The above information should give you a primary understanding of LEDs and what to look for, but if you have more questions or would like more info on a specific product, we are here to help. Just contact Goodchip today to chat with our Tech Support Team.
