I see that few companies are trying to integrate the Hardware required to drive CFL and the communication module together in the existing small base of the CFL bulb, If we think outside the box and have this hardware external to CFL/LED bulbs, then it will be easy to maintain/upgrade the hardware and also the initial/replacement cost of the bulb will be cheaper.
Any thoughts on this?
The problem is the screw-in bulb form factor. Shoehorning a power converter and heat-sink into a standard size bulb will continue to yield substandard replacements. The I/O for traditional bulbs is inadequate (dimmers and 3-way switches) to make significant improvements in usability. The power supplies need to be made more reliable and their heat positioned away from the LED module. The fixture needs to provide the heat sink for the LED. I have seen some of this with integrated LED pot-lights, and some desk lamps, but not in other built-in lights for consumers. The problem is that the fixture industry does not see themselves in the electronics industry. Second is that for long-lived fixtures, the consumable replacements are not standardized - should there be separate power supply and LED replacement options?
Lighting research and adoption by the society is very slow I agree with Himanshu Gupta' comment. Event today still at most of the places we see the conventional switches, none of the affordable and reliable replacement of the mechanical switches are there in the market today. Yes but it is equally true to have development, so the show must go on.
Why not a single adjustable light bulb? Today we buy 40, 60, 75, 100, and 150 watt light bulbs. Why not a single bulb with a base switch to set the desired output? It could even have a second switch to set the desired color temperature. Then a single bulb could fill all applications in legacy light fixtures and avoid the need to warehouse a variety or depend upon unreliable "three way" switches. One challenge is device footprint. The high wattage (CFL and LED) bulbs are too big to fit into many light fixtures. Once size and cost are reduced, the "one bulb fits all" can become a reality.
There are a couple of questions needed to be addressed before next generation lighting solution becoming widely adopted.
1) Price is always the main driver. Price/ Lumen is a good way to look at it. However, if the price of LED lighting is not getting closer to the price of CFL, the adaptation will be very slow.
2) Life time of the product is another driver. Compared to incandescent light bulb, CFL last 3-5 times as much. The price reflects that properly. CFL does take 3-5 years for the crowd to adopt. The adaption in the States doesn't really take off until PG&E heavily subsidize few years ago. LED lighting is claim to be lasted 10 times longer than incandescent light bulb. Now, consumers will be more than happy to see a proof.
3) Availability of different lumen bulbs is important to the market. I used different brightness in different area. For example, I would like the den to be bright so that I can read and work better. I prefer to have my living room a little bit dimmer in addition to that I am able to control the brightness. Dimmable light bulb is a must. The last time I checked, LED light bulb has 40W equivalent incandescent light bulb. Where is the 100W equivalent?
4) If the BOM cost is heavily driven by the power electronic of an LED light bulb, shall the form factor and the presentation of the product be changed so as to increase the rate of adaptation?
"Intelligent lighting parameters should enable the user to adjust the quality, the quantity and the direction of light."
...sounds interesting...I get "the quantity", "the direction", but what is it meant by "adjust the quality" of light? Color?
