Samsung Enhances Chip-Scale LED Package Lineup with Industry’s Highest Luminous Efficacies Samsung achieved the industry’s highest light efficacies for its fillet-enhanced chip-scale package (FEC) LED lineup – LM101B, LH181B and LH231B.
In the early stages, CSP (chip-scale package) LEDs had not been widely used due to relatively lower efficiency level compared to conventional LED packages. The new upgrade… |

JK Flip-Flop: Circuit, Truth Table and Working The term digital in electronics represents the data generation, processing or storing in the form of two states. The two states can be represented as HIGH or LOW, positive or non-positive, set or reset which is ultimately binary. The high is 1 and low is 0 and hence the digital technology is expressed as series of 0’s and 1’s. An example is 011010 in which each term… |

Simple Air Flow Detector Circuit Detection of air flow is useful in many projects and applications. Here we are building a very simple circuit to detect the air flow presence. This circuit doesn’t require any fancy stuff like Resistance Temperature Detector (RTD) or Zener diode etc. Here we are using a simple AC bulb filament with some cheap component to detect the air. This is very interesting project… |
