What is LED Light Source |

A light-emitting diode (LED) is a semiconductor light source, which is widely used in LED lights today. SMD LED is one of the LED encapsulation, which is widely applied in LED tube lights. This article will give an introduction to the LED, concerning the development of LED; structural components of LEDs, types of SMD LEDs, and application of LEDs.

History and Development of LEDs

    When talking about of LED, we can get the general idea of LED phenomenon in our daily life. It occurred to us as indicator light on the flashlight and LED on display board for the first time. It is small in dimension and glows yellow light. SMD and DIP are two typical different ways of LEDs encapsulation. DIP(dual in-line package) LED is the previous LED encapsulation with the advantage of high brightness and corrosion resistance. SMD(surface mounted device) is the advanced technique to solve the inconsistancy and high failure rates of DIP. SMD LEDs bear well consistancy and stability, for the automatic process and high assembly density. As a general rule, DIP LEDs are used in outdoor lighting, while SMD LEDs are applied in indoor illumination.This is the basic knowledge of LEDs we keep trace of LEDs application in the past. (Shenzhen Syhdee Manufactory Co. Ltd.)Our company adopts SMD LEDs as LED tube light source, so SMD LEDs shall be introduced as bellow:

Constitution of LEDs

    LEDs consist of five main parts: LED holder, LED chip, silicon and gold leading wire. 

    LED holder is the cover that stands the LED chip and prevents the inner structure from corrosion and drop. LED holder is made up of copper raw material with good conductivity and heat sink. Phosphor is used in LED for lighting. Phosphor with best quality can lessen the light failure and extend lifespan. LED chip is the core of LED. According to the dimension, LED chip size varies from 7×15", 9×15", 9×20", 9×25". High quality LED chip can assure the LED lights efficiency. 

LEDs: SMD 2835&SMD 3528

SMD 2835 and SMD 3528 are the two LED dimensions used in LED tube lights. LED SMD 3528 can glow 24-26lm with 60mA driver current while LED SMD 3528 8-9lm with 20mA current. Compared with SMD 3528 and SMD 2835, the latter of which possesses wider luminous surface and heat-dispersing surface with higher current, thus making LED SMD2835 the good demand of more customers. However, SMD3528 has long history of lifespan warranty. In the governmental project, LED SMD3528 is accepted by LED tube replacement contractors.

Smart Lighting: New Experience for LED Lighting

In the 21st century, it is an epoch-making event for the biggest revolution in mobile phone. Smart phone changed the way we used generally with finger clicking on the phone keyboard instead of screen touching. Likewise, LED lighting, as the emerging industry, is changing the way we experience it .

Smart Lighting: New Concept, New Way

Smart lighting is no longer a new concept for us. What is smart lighting? Applying new technology to LED lighting to control LED lighting procedures, we can make sure less energy , more effectiveness. Moreover, smart lighting allows users to both use and feel the way, which can benefit our health and mood. This is a new way for our LED lighting experience.

Smart Lighting Technology 

Power line Carrier technology: Power line Carrier technology is one that adopts traditional wires to deliver signals and data. Compared with the wireless way, power line carrier has its advantage, which could apply the set line system without any changes and make sure the stability of signal input. Applying power line carrier technology on LED lighting is one way that employed the conventional line setting advantage.

Buss Technique: Buss technique refers to one way that combine all the components with the buss line, which is the passage for data delivery, exchange, share and control. It was applied in LED lighting on the purpose of taking charge of the whole wiring system automatically and intelligently.

Wireless Communication Tech: To solve the disadvantage of wiring communication, wireless communication is one virtual tech that delivers and exchanges the data signal by electromagnetic signals, which can achieve remote-control function.

Smart lighting combines the three multiple high techniques with LED lighting techniques to make smart LED lighting come true.

Smart Lighting Application

For several years development, smart LED lighting had been used in commercial lighting and office lighting. Household lighting will be the next milestone.
