SummaryLast days,I bought a new house and I am considering how to decorate it. when thinking about wall-lighting sconces.My project is to place an array of LED strips on the walls,covered with translucent(or in some cases,opaque!) Yeah,Plexiglas plates mounted a few centimetres away. That's the plan anyway...PreparationAt first, I need a 18W power supplies small enough to fit into an electrical box.Finally,I chose a power supply.This product could provide a full 1.5A without collapsing.Howev ...
SummaryAs we all known,better knowledge of the absorption and scattering of light inside the LED,the performance of white LEDs can be improved.Yeah,LEDs can be made even more efficient and powerful.When in May,2017,researchers who from the University of Twente and Philips Lighting have developed a new method which can lead to efficiency improvement and powerful design tools. They found a detailed way to describe the light that stays inside the LED by absorption and scattering. This is very valua ...
SummaryChristmas is coming,as well as the New Year's Day. In keeping with the festive lighting of the holiday season,there are various LED lighting architecture in the world. Now let me take you to tour the landmarks lit with LEDs. In the touring of this LED architecture, I will also introduce how this landmarks be done. Well,these These attention grabbing displays are dependent on products that can deliver a wide range of colors, and a control scheme that allows lighting designers to f ...
SummaryAs is known,one of the main barriers to a wider adoption of OLED technology resides in its lack of efficiency compared to fluorescent lamps or Light-emitting diodes(LED).  The SOLED project hoped to solve this problem using chiral organic semiconductor structures. The difference is undisputable: when put side by side with an LED display (display modules), its OLED counterpart will stand out thanks to its sharper images, better contrast and crisp colours.BodyEnergy efficiency, however ...
SummaryAs we all know,in case of macro photography or close-up portraits,the availability of a proper lightning source can dramatically improve the final result.  For this a soft light, possibly white, not a flash is essential.  The LED ring project we are presenting is not only useful for still photography but can be used for video and stop-motion animations.Project GoalsSome years ago I started a similar design of a non-portable, white ring light based on a small round neon tube, but ...
Article provided by University of Illinois at Urbana-ChampaignArticle edit by kynixA new methord to make Green LEDs more brighter and more efficient have been developed by researchers who at the University of lllinois at Urbana Champaign. Researchers have created gallium nitride(GaN) cubic crystals grown on a silicon substrate that are capable of producing powerful green light for advanced solid-state lighting. "This work is very revolutionary as it paves the way for novel green w ...
There are a good news that ERP Power LLC,one of the leading provider of small,smart and connected LED drivers for the lighting industry,lanched the world's smallest programmable output drivers with wireless communication for indoor lighting applications on 25.Oct.,2017 and demonstrated it on 27-30th,Oct.,2017 at Hongkong.According to Michael Archer,the CEO of ERP,"ERP is accelerating the Internet of Lights by embedding intelligence, connectivity and dimming into a very small footprint,e ...
As one of the electornic hobbier,I like to make all kinds of electronic projects. Every time I ended an electronic project and saw my trophy,I am so happy and perfectly satisfied.Today I wolud like to share an electronic about LED motorcycle helmet. The costs of helmet you made by yourself are less and meaningful. Now let me introduce it step-by-step.Parts we need:Helmet ( any kind you like)LED RGB Addressable StripQduino MiniLiPo BatteryBattery ChargerString or threadTapeHot GlueSoldering kitWi ...
The global lamp market has undergone tremedous changes over the last several years. Even government regulation,declining packaged LED and other component prices, and technological advancements have all played a major role in the continued penetration of LED into the overall market. Obvioulsy, LED lamps are the future of lighting, and there is a new invention using LEDs has been pushing out that Osram,a lighting company that offers innovative and sustainable lighting solutions, has revealed  ...
A few months ago,I have see an article about desinging a nixie tube clock with an ATmega328 and ESP8266,and I had a big interest in it and I made one immediately according to the article's step.The ESP8266 connected to a Network Time Protocol (NTP) server was cheaper to implement than using an RTC due to the discrepancies between the defined clock speed and actual clock speed.You can see the picture,nixie tubes came into existence during the time of vacuum tubes and before LEDs (at least in  ...
There is no doubt that the use of LCD headlamp is a succcessful further step towards digitalizing lighting. LCD headlamp which enables complex functions will also be relevant to autonomous driving.Let's talk something about the following research project about developing a headlamp basics on a LCD (  Full name is Liquid Crystal Display )which made by HELLA and seceral partners.This technology is an good example already known in the home entertainment field.About The ProjectIn the contex ...
Today I want to share an LED strobe design project I found in electronic-lab, which you can do it by yourself. Strobe provides regular flashes of light. Usually Strobes are designed using Xenon Tubes. Here is LED based simple solution that can be used as strobe for entertainment and events and also as warning signals. Project is based on PIC16F1825 micro-controller with two digit frequency display.Project provides TTL output signal, frequency 1Hz-25Hz, Tact switches provided to set the frequency ...
Today I want to share a project of making a simple automatic street light controller using relay and LDR I found in circuitdigest with you.You have seen street light which automatically gets turned on in the night and gets turned off in the morning or day time, there are sensors who senses the light and control the light accordingly. These Street lights are an important project in smart cities.So here in this project, we are going to make a Simple Automatic Street Light Controller Using Relay an ...
When designing a custom lighting solution, there are many different goals to take into consideration. One of the most essential may be reducing the power supply needs of the system. Doing so can provide further benefits, such as improving reliability and expected shelf life, and reducing space and size constraints. Benefits often come with tradeoffs; traditionally, when you reduce power you may need to reduce brightness at the same time.The good news is that this doesn’t always have to be the ca ...
The US Department of Energy (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) has detailed a living laboratory test of solid-state lighting (SSL) and controls on a 40,000-ft2 floor in a New York commercial office building. Berkeley Lab worked with the Building Energy Exchange (BEEx) on the LED lighting project that also included comprehensive light and occupancy sensors along with connected window shade controls. Berkeley Lab believes the work will speed market adoption of sma ...
