2. One feature I wish my light bulbs could have (without buying a $50 USD Philips Hue) is to automatically shift the color temperature to match the time of day. I use "f.lux" on my PC and I can tune the average color temperature of my monitor at different times of the day. I know scientific research has shown it's best to stay away from blue colored light late at night. For example, I would change all my bulbs in my bedroom and office room to this type if they were not so expensive like Philips Hue. I could probably justify spending $15 USD/bulb for this feature.
The technical hurdles are challenging (to do inexpensively)...How will the bulb know where it is on the planet? How does it know what time it is? A few quick thoughts: It could have some sort of NFC, IR, or some other crude communication interface interface which could program its location and time/date once...but then you need a RTC in the bulb, and I think that's probably a bad idea since I would not suggest putting a battery inside a blazing hot lightbulb. Another idea is to use powerline communication and some centralized hub that plugs into an outlet in your house. But then you need some magnetics and other bulky components to sense that signal. Finally, I wondered if you could use the atomic clock signal that many countries have, i.e. US in Texas (I think) and I think there are a few in China too. But that's never going to be so reliable, and you probably still need to have an RTC + battery.
Honestly, the cheapest/simplest solution to getting communication to a bulb is probably....WiFi or Bluetooth, especially given the low cost nRF chipsets that exist now, as much as I wish that wasn't true.
So, really I've got no good ideas on that, but I do wish that I could just screw in a light bulb and it would automatically change the color temperature perfectly, to match the time and my location. But, I think it's not so simple!
Hi, Tim:
I've discussed this idea with my colleagues, this is a brand new idea for bulb.
But also the most difficulty is how to tell the bulb the time.
1. RTC need an extra power supply...
2. Use low frequency radio to sense the time, the feed back is signal weak after setup in the building...
3. As you mentioned, receive from GNSS satellite , but the receiver/decoder size and cost cannot accept...
We'll continue discuss this topic.I wouldn't worry about having an RTC, or sensing the time. People generally don't need a bright, low colour temperature, or dim high colour temperature light. Which is why I suggested dim to warm, i.e. reducing the colour temperature, along with the light output, to mimick natural light sources such as the sun.

I agree with this approach, but how does the bulb have any concept of knowing what time it is in the first place?

The user sets the brightness and the colour temperature is automatically adjusted. I don't want any fancy AI in a light bulb, even though it would be fun to design.

Are you talking about a bulb which automatically changes color temperature as it is manually dimmed from a wall-plate dimmer?
Interestingly enough, many LEDs do this "naturally" already, i.e. at lower forward current, the color temperature goes down, but usually the shift is probably not much more than 500-750K, IIRC.
I am talking about a bulb which after installation, automatically dims and/or changes color temperature in accordance with the time of day. i.e. At noon, 5000K, at dusk 3500K, at night 2200K, etc. I don't want any human intervention, no programming, no opening an app. So, the bulb itself needs some intelligence to determine when it is day and when it is night.
As Jon Paul suggested, and may very well already exist(!), the bulb can have a light sensor (or two). The bulb can be shut off for a short amount of time, un-noticeably and periodically throughout the day, to make this ambient measurement. I think no need to be scared of 'AI' in this context. The learning algorithm I'm suggesting can probably be run on an 8051, since it will have 10's of minutes to process the data . Basically, depending on the environment, room X's night-time may look different than room Y's night-time. (i.e. In a city, perhaps a streetlight shines in the window at night, but on a farm there is total darkness.) Hard pre-programmed thresholds may give...unexpected results.
Maybe I'm talking out my ass, I don't know. I kinda want to try now though!
No doubt it's possible and would certainly be a fun project, but it isn't something I'd be interested in installing in my house. There's too much scope for it to go wrong. I'd rather have a simple, dumb manual control.
Edison-base bulbs have been around for a while. Staying with a standard interface as the technology advances to new forms of light can be a sensible strategy for domestic purposes, rather than forcing consumers to change sockets when not truly necessary.
but for traditional styles screw-in retrofit lamps are arguably the best option
