Less lights is always a matter of less photons, not less powerful or less bright photons, even with incandescent bulbs, it always only changes how regularly a photon is emitted.įor the color, we combine several LEDs of different colors so their combinations can achieve the colors we need. It effectively turns the LED on to emit a few photons, then turn it off to stop the photons flow, then on again, … LED controllers (inside your Hue bulbs, not the Bridge) are doing exactly the same thing, but over such a short interval that you don’t see it blinking. If you want 50% light, you leave it on a half hour, and turn it off the next half hour, if you want 25% light, you leave it on a quarter hour and turn it off for the next 45 minutes. If you want 100% light, you leave the bulb turned on the whole hour. Imagine you have a light switch and have to control how much light you get in a room over a period of 1h, but have no way to dim the light bulb. Pretty simple, to control the brightness, we use what we call pulse-width modulation (PWM), which basically means we quickly alternate between it being on and off, with different time lengths, to change the quantity of photons it emits during the same time interval. So how do these LEDs we have in bulbs and strips emit several colors and handle brightness? While not strictly monochromatic, the emitted light spectrum is very narrow, and cannot be changed, a LED can only emit a single color.Īs for the brightness of an LED, it depends on the band gap again, either the voltage is sufficient for an electron to cross the junction and a photon is emitted to release the energy used to cross it, or the voltage isn’t sufficent and nothing happens.Ī single LED module always emits the same color, and is an on/off process – it emits photons or doesn’t, there are no “less bright” photons. The light wavelength depends only on the junction band gap, which depends on the materials used. LEDs are electronic components that spit out photons when electrons change their power level when crossing their junction. The long explanation (but still highly simplified, hopefully still understandable): The following explanation is based on my current understanding of LED technology and matches usual recommendations about LEDs lifespan. It brings entertainment via our TVs to a whole new level.”
RASPBERRY PI HUE SYNC MOVIE
“This innovative app offers our users a new way of experiencing TV content by immersing themselves in their favourite movie or game. “We’re excited to bring the Philips Hue Sync TV app to Samsung TVs together with Philips Hue,” says James Pi, Head of Experience Planning Group, Visual Display Business at Samsung Electronics. And unlike many other current app solutions, Philips Hue does without a subscription model for the Sync TV app, so you only have to pay once. Of course, that’s a lot of money, but you also have to keep an eye on the relation: For the Hue Play HDMI Sync Box, you have to put 269.99 euros on the table the box is rarely available in stores for less than 200 euros. However, there is a big catch: the app is not free.ġ29.99 euros are due for installation. The Philips Hue Sync TV app will be able to be installed directly on TVs from 5 January, with support for Samsung Smart TVs built in 2022 (Q60 model and above). The Philips Hue Sync TV app for Samsung has a catch
We are proud to offer more immersive and personalized experiences with our new Philips Hue Sync TV app and look forward to bringing this new way to enable surround lighting to living rooms across the world,” says Jasper Vervoort, Business Leader Philips Hue at Signify. It does not store any personal data.“This is an incredible milestone in Philips Hue’s home entertainment journey and our ever-evolving partnership with Samsung.
