LED Lamp [pic] An LED lamp (or LED light bulb) is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. LED lamps offer long service life and high energy efficiency‚ but initial costs are higher than those of fluorescent and incandescent lamps. Chemical decomposition of LED chips reduces luminous flux over life cycle as with conventional lamps. Commercial LED lighting products use semiconductor light-emitting diodes. Research into organic LEDs (OLED)‚

WAYS TO REDUCE THE EFFECTS OF GLOBAL WARMING Global Warming refers to the gradual increase in the Earth’s temperature as a result of the growing concentration of human induced green house gases which are carbon dioxide‚ chlorofluorocarbons and hydro fluorocarbon in our atmosphere. Global warming can be caused by the use of fossil fuels‚ and industrial or agricultural processes. Man-made emissions are adding to the amount of carbon dioxide already being naturally released. These

Application of Organic Light Emitting Diode (OLED) for Display Systems: Advanced Characteristics and Possible Solutions to Challenges 1. Introduction The first organic light emitting diode (OLED)‚ which was an innovatory of electroluminescence that emits light using organic materials‚ was reported in 1987 (Tang & VanSlyke‚ 1987). OLED displays are constructed by surrounding a glass or plastic substrate with organic compounds that emit light when current passes through them (Askari‚ 2014). Continuous

PROPERTIES AND CHARACTERISTICS OF COMMON INDUSTRIAL MATERIALS “LCD‚ LED & CRT” LCD COMPOSITION A liquid-crystal display (LCD) is a flat panel display‚ electronic visual display‚ or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden‚ such as preset words‚ digits‚ and 7-segment displays

engineer named Bertho Stoltiens shared his shiny earrings Blinkring designed‚ The earrings have a diameter of about 31mm eardrop‚ the total number of 12 LED were set in a circle above. This concept of the earrings is based on standard Cr2032 button-type battery with a slightly larger circular printed circuit board (PCB)‚ the operation of the LED parts required is a small circle on the board outside the battery. Stoltiens came across a number of challenges when carrying out the design case，because
