This could be interesting (as I have also been looking for something to reduce CO2 and VOC in the home), but the important part is probably this:
> only require a visible light source that also produces heat—such as a halogen or incandescent bulb—and a lampshade coated with a thermocatalyst.
My read is that you wouldn't be able to do this with an LED, and I only use LED lights around the house. Isn't any heat production from a light is an inefficiency to begin with?
- frereubu 3y agoThe article says that they're "extending the technology so it will also be compatible with LEDs" but as you say it seems to be triggered by heat so I'm not sure how that will work, but it would need to given the phasing out of incandescent (and presumably halogen?) bulbs.
- rantallion 3y agoThe last paragraph explains: > Unlike halogen and incandescent bulbs, however, LEDs release too little heat to activate thermocatalysts. So Kim's team is developing photocatalysts that are stimulated by the near-UV light emitted by LEDs, as well as other catalysts that transform part of the LEDs' visible light output into heat.
- baq 3y agomy LEDs have UV-absorbing coating that emits visible light...
- woadwarrior01 3y agoI've got Philips Hue LED lights around the house, and although the bulb remains relatively cool, the base gets surprisingly hot (75-80C) after they've been on for a couple of hours.
