The Success of the LED Lamp
LED Lighting is more important than you think it is. Start Using Alternative Energy, like Wind Power and Solar, Tidal and even Magmatic.

On September 24, 2009 the DOE announced that Philips Lighting North America was the first to submit lamps in the category to replace the standard 60 W A-19 "Edison screw fixture" light bulb, with a design based on their earlier "EnduraLED" consumer product.
On August 3, 2011, DOE awarded the prize in the 60 W replacement category to Philips bulb after 18 months of extensive testing. The 10-W, 900-lumen Philips bulb was made available to consumers in April 2012.
The same day, CREE demonstrated a prototype lamp producing 1330 lumens with a mere 8.7 W of input power. While the CREE lamp has not undergone DOE reliability testing and no commercial release date was promised, it is an indication that the "21st Century Lamp" performance levels may soon be within reach of commercial products.

The White LED Lamp is a Success today, more and more firms are manufacturing them. Millions are using it and is moving forward taking over the slots once occupied by CFL Lamps.
Still Filament and other Lamps are in use, even i like it much. CFL reliability and quality has improved. Then the LED Lighting has far too many Advantages and will be the Default Lighting Product of the future. It can easily adapt to the 24V Low voltage Standard, with Solar Energy Interface too.
The AC to DC converter can be designed in various ways. The SMPS, the CFL Lamp Driver and this Mains Bulb LED driver all belong to the same Electronic Species.
First the 230V/110V at 50Hz/60Hz mains voltage is converted to DC with a diode bridge and filter cap. Not to forget protection and EMI filter circuits made of passive components.
Then it is an Oscillator that switches at High-Frequency, chops the 200V or 300V DC, say around 200 KHz. Then this AC is Stepped-Down with a High-Frequency Ferrite Transformer. Rectify the AC and use it to drive lamps with the current limit controls. The reliability of power devices and the Isolation in the Small Ferrite Transformer determine the life and safety of the bulb.

We moved from Warm, Soothing and Healthy Edison Filament Lamps to CFL Lamps which are Energy Efficient, Bright but harsh on the Sensitive Eyes.
Energy Efficiency is of paramount importance for this age. Then, the light should be healthy for the eyes too. Eyes are very precious too.
That is the reason we need to Switch to LED lighting. It consumes low power, more reliable than CFL and gives Excellent and Safe Lighting.
LED lighting is expensive, as the Technology is slowly gaining acceptance. Please also bear in mind that low quality and unreliable LED products will also be in the market. In time, things will get seasoned and affordable quality products will be standard in all stores.
You can Contribute by trying them out and experimenting with its applications in home, office, vehicles and helper robots. Only those that design lamps that withstand Surges, Brown-outs, Lightning Strikes, Spikes will Shine just like the Lamp above

A Warm White LED is great Feng Shui for a Hobbyist's Desktop or Workshop. A DIY Table Lamp or a Lathe Lamp with these Warm LEDs create Positive Energy, for not just your Home but for the Entire Neighborhood. This idea, is in the form of riddles in Ancient Chinese Manuscripts, I hope the Yellow Emperor does not see this post.
Yellow Emperor - Known as an early inventor. He holds the patents for The South Pointing Chariot, Diadem, Football, Silks, Dyes and Grain Farming too. A Musical instrument called Guqin too!
LED Lighting is gradually replacing CFL Lamps because they are more frugal in drawing energy and last many years. These have been around for some years and the technology is progressing. Now LEDs which show the illuminated objects in their true colors (like sunlight) are also coming. Due to the green initiatives of many countries, people have become aware and also implementing these solutions. These become a necessity when you start using Solar Panels for Home Power.
The CFL lamps have reduced the use of the Filament Bulb due to lower power consumption. Now LED lamps may have to replace CFL but it is progressing. Few years ago only Conference Rooms, Media Events or Product Exhibits could afford the LED lighting, it was a Novelty. Now LEDs are affordable and Reliable Driver Solutions are also available.
The problem like in most Tech Learning Curves is now the SMPS drivers for these LED Arrays. The LEDs are reliable, but drive systems are still having problems. Cost effective drive systems from make affordable lighting possible. But due to Quality and Reliability issues, system integrators face implementation problems.
When Mitutoyo the maker of the Best Metric Tools started decades ago, it faced a tough market. In those days, Japanese Goods were known as cheap and low quality in Europe and America.
Companies like Mitutoyo, Sony, Misubishi, Hitachi and many more changed the scenario completely. Now Japan is a Symbol of High Quality. Every new firm has to go thru those Stages.
A genuine long term commitment to R&D and Quality will build the reputation of Brands, Firms and entire Regions. Anyway, here are some nice resources to help build Drivers and Systems for LED Lighting.

These Semiconductors and Applications are Excellent, the driver systems have to be engineered and perfected by manufacturing and development. A casual or quick results method will backfire. Hence system integrators start by working closely with the vendor (Vendor Development) of Drive Systems. Finally deliver only systems that are Robust and Burnt in. The other option, work with know friendly customers as a Beta Testing and learning phase, till systems reliable for global deliveries.
