Rgb Led Strip Whats it called: when you have LED's on the back of your TV that change color to match whats on the screen?
- I recently installed RGB LED strips behind my tv to reduce eye strain.
- Last year I read about (and saw a movie about) a RGB controller that can change the color of the LED strips to match the image color on your TV in real time, furthermore reducing the strain on the viewers eyes.
Can anyone help me out with tracking down this controller, or information on this technology?
I found out what it's called...
Ambilight ! ...and apparently it's exclusive to Philips TV's at the moment... I hope someone out there can point me in the direction of an aftermarket controller?
I've heard of ambient lighting but not sure if that's quite it

Is there a way to add a second controller to my rf controller?
I have two rgb led strip controllers w/ remotes but I only want to use one remote to control both controllers, which would mean 1 remote controls both led strips
It depends whether the two controllers can be networked or to use the same RF (or IR) codes. If so, one remote can control both. You don't say what you have, but see the link for one brand that specifically mentions networking.
Rgb Led Strip What are the differences between Common Cathode, Common Anode, and Manual Control LED`s?
Looking to build a RGB strip for a light controller (7 color fade, flash... lol). But not sure what LED i`m supposed to be leaning towards... never heard of the term Manual Control LED before now.
Diodes (of which LED's are one type) conduct electricity in only one direction. In the other direction, it stops any electrical flow unless the voltage is so high that it breaks down the diode, damaging it..
So, to get an LED to light up, you need to apply a positive voltage to the anode, and ground to the cathode. Or if you apply ground to the anode, then you must apply a negative voltage to the cathode.
With a modular LED array, you're going to apply switches to one end, to individually control each LED in the array, while the other end will share the common return wire. If you're working with a positive power supply, then you need a Common Cathode array since they will all share the same ground return.
Conversely, if you using a negative voltage, then that will need to be fed individually to each cathode as needed, and the Common Anode will be the shared ground return.
LED's are not, by nature, manually nor automatically controlled. It's the switching circuits designed to address the LED's that will either be automatic or manual. There may be some IC chips that include control circuitry for LED's, but they would be manual (for simplicity of flexibility) unless you design the extra supporting automatic circuitry to augment them.

Light Emitting Diode, or Issuing Diode of Light
Characteristic
LED is a diode semiconductor (junction P-N) that when energized emits visible light for that LED (Issuing Diode of Light).
The light is not monochrome (as in a laser), but it consists of a ghastly band relatively it narrows and it is produced by the energy interacções of the electrão. The process of light emission for the application of a source eléctrica of energy eletroluminescência is called. In any junction P-N polarized directamente, inside of the structure, close to the junction, they happen recombinations of gaps and electrões. That recombination demands that the energy possessed by that electrão, that until then was free, be liberated, what happens in the form of heat or light photons.
In the silicon and in the germanium, that you/they are the basic elements of the diodes and transistors, among other components electrónicos, most of the energy is liberated in the form of heat, being insignificant the emitted (due to opacity of the material) light, and the components that work with larger current capacity gets to need of irradiadores of heat (dissipadores) to help in the maintenance of that temperature in a tolerable landing.
Already in other materials, as the gálio (GaAs) arseneto or the gálio (GaP) fosfeto, the number of light fotões emitted is enough to constitute quite efficient light sources.
The simplified form of a junction P-N of a led demonstrates his/her eletroluminescência process. The material dopante of an area of the semiconductor contains atoms with an electron the less in the valency band in relation to the material semiconductor. In the connection, the íons of that material dopante ("taker" íons) remove electrons of valency of the semiconductor, leaving "gaps", therefore (or holes), the semiconductor becomes of the type P. In the other area of the semiconductor, the material dopante contains atoms with an electron the more than the pure semiconductor in his/her valency strip. Therefore, in the connection that electron is available under the form of free electron, forming the semiconductor of the type N.
The semiconductors can also be of the type compensated, that is, they possess both dopantes (P and N). In this case, the dopante in larger concentration will determine what type belongs the semiconductor. For instance, they are existed more dopantes than they would take to P than of the type N, the semiconductor will be of the type P. That will implicate, however, in the reduction of the Mobility of the Bearers.
The Mobility of the Bearers is the easiness with that loads n and p (electrons and holes) cross the crystalline structure of the material without colliding with the vibration of the structure. As larger the mobility of the bearers, minor will be the loss of energy, therefore lower it will be the resistividade.
In the area of contact of the areas, electrons and gaps if recombinam, creating a fine layer practically exempt of load bearers, the call potential barrier, where we just have the íons "donors" of the area N and the "taker" íons of the area P, that for they present not load bearers "isolate" the other gaps of the material P of the other electrons free from the material N.
A free electron or a gap can only cross the potential barrier by the application of external (direct polarization of the junction) energy. Here it is necessary to emphasize a physical fact of the semiconductor: in those materials, the electrons can only assume certain levels of energy (discreet levels), being the valency bands and of transport the one of larger energy levels for the electrons occupy.
The area understood among the top of the one of valency and the inferior part of the one of transport is what is called "forbidden band." If the material semiconductor is pure, he/she won't have electrons in that band (then to be called "forbidden"). The recombination among electrons and gaps, that it happens after having won the potential barrier, can happen in the valency band or in the forbidden. The possibility of that recombination to happen in the forbidden band if it owes to the creation of electronic states of energy in that area for the introduction of other sludges in the material.
As the recombination happens more easily in the closer level of energy of the transport band, it can be chosen the sludges appropriately for the making of LEDs, in way they exhibit her/it appropriate bands for the emission of the color of wanted (specific wavelength) light.
Operation
The emitted light is not monochrome, but the colored band is relatively narrow. The color, therefore, dependent of the crystal and of the dopagem impurity with that the component is manufactured.
The led that uses the gálio arseneto emits infra-red radiations. Taking drugs with match, the emission can be red or it yellows, in agreement with the concentration. Being used gálio fosfeto with dopagem of nitrogen, the emitted light can be green or it yellows.
Nowadays, with the use of other materials, it is gotten to manufacture leds that emit light blue, violet and even ultra-violet.
They also exist the white leds, but those are usually issuing leds of blue color, covered with a layer of match of the same type used in the fluorescent lamps, that absorbs the blue light and it emits the white light.
With the barateamento of the price, his/her high income and his/her great durability, those leds become great substitutes for the common lamps, and they should substitute them the medium or long period.
They also exist the called white leds RGB (more expensive), and that are formed by three "chips", a red (red R), a green (green G) and a blue (blue B). A variation of the leds RGB are leds with an integrated microcontrolador, what allows that is obtained a true show of lights just using a led.
He/she is the physical aspect of some leds and his/her electric symbol.
In general, the leds operate with level of tension from 1,6 to 3,3V, being compatible with the circuits of solid state. It is interesting to notice that the tension is dependent of the length of the emitted wave.
Like this, the infrared leds usually work with less than 1,5V, the reds with 1,7V, the yellows with 1,7V or 2.0V, the green ones among 2.0V and 3.0V, while the leds blue, violet and ultra-violet usually need of more than 3V.
The necessary potency is in the typical strip from 10 to 150 mW, with a time of useful life of 100.000 or more hours.
As the led is a junction device P-N, his/her characteristic of direct polarization is similar to the one of a diode semiconductor.
Being polarized, most of the manufacturers adopts an identification "code" for the determination expresses of the terminals THE (anode) and K (cathode) of the leds.
In the round leds, two codes are common: he/she identifies the terminal K as being that close to a small one chamfers in the lateral of the circular base of his/her involucre ("body"), or for being the shortest terminal of the two. Manufacturers that adopt the two identification forms simultaneously exist.
In the rectangular leds, some manufacturers mark the terminal K with a small "enlargement" of the terminal close to the base of the component, or then they leave that shorter terminal.
But, it can happen of the component not to bring any external reference of identification of the terminals. In that case, if the involucre is semi-transparent, it can identify the cathode (K) as being the terminal that contains the wider internal electrode than the electrode of the other terminal (anode). Besides wider, sometimes the cathode is lower than the anode.
The issuing diodes of light are also used in the construction of the alpha-numeric displays.
There is also leds bi-color, that are constituted by two junctions of different materials in a same involucre, so that an inversion in the polarization changes the color of the emitted light of green for red, and vice-versa.
They still exist bicolor leds with three terminals, being one to work the junction doped with material to produce green light, other to work the junction doped with material to generate the red light, and the third party common to the two junctions.
The common terminal can correspond to the interligação of the anodes of the junctions (bicolor leds in common anode) or of their cathodes (leds bi-color in common cathode).
Although it is usually treated by bicolor (vermelho+verde) led, that led type is in the reality a "three-colored" one, since besides the two independent colors, each one generated in a junction, those two junctions can be polarized simultaneously, resulting in the emission of orange light.
Usually, the leds are used in substitution to the signalling lamps or pilot lamps in the panels of the instruments and several apparel. For fixation in those panels, it is common the use of plastic supports with thread.
As the diode, LED cannot receive tension directly among their terminals, once the current should be limited so that the junction is not damaged. Like this, the use of a resistor limitador in series with Led is common in the circuits that use him/it.
To calculate the value of the resistor the following formula it is used: R = (Vfonte-VLED) / ILED, where Vfonte is the available tension, VLED is the correct tension for LED in subject and ILED is the current that he can support with safety.
Typically, big (of approximately 5 diameter mm, when round) LEDs work with currents of the order from 12 to 30 MA and the small (with approximately 3 diameter mm) ones operate with the half of that value.
Like this:
We adopted I1 = 15 MA and I2 = 8 MA, Vfonte = 12 V, VLED = 2 V:
R1 = (12 - 2)/0,015 = 10/0,015 = 680*
R2 = (12 - 2) /0,008 = 10/0,008 = 1K2*
We approximated the results for the closer commercial values.
LEDs don't support reverse (Vr) tension of significant value, could deteriorate them with only 5V of tension in that sense.
Therefore, when fed by tension C.The., LED be accompany of a diode rectifier in antiparalelo (inverted polarity in relation to LED), with the purpose of driving the semi-cycles us which him - LED - it is in the cut, limiting that reverse tension around 0,7V (tension direct maxim of the diode), a value sufficiently low so that his/her junction doesn't deteriorate.
It can also be adopted a connection in series between the protection diode and LED.
Rgb Led What is the piece of electronics that limits voltage? Like a 14 volt car still producing only 12 volts?
Like if I ran a wire to some RGB LED's. I dont want the voltage to change on the line out to them, so how do I just always limit the voltage to 12 volts? I know this is possible. I have seen the electronics before, I just dont remember the name!
Well, the issue isn't voltage with LEDs but rather current. The current to an LED must be limited using resistors. An LED can care less of the voltage as the resistor will take care of this.
Hit me up with some info and I can get you on the right track.

Spinning LED-Ball (RGB)
High-Power LED Wall-Pak Luminaire Reduces Cost of Wall Washing and Security Lighting
TORRANCE, CA—October 1, 2009—LEDtronics® announces its first series of energy-efficient LED replacements of wall-pak luminaires for wall washing and security lighting. The high-power WWL20-24X2W-XPW-001W floodlight runs on a wide range of voltages, from 100 to 277VAC, consuming only 56 watts of power. Easily mountable on walls, ceilings or floors indoors or outdoors, the LEDtronics wide-beam and weatherproof Wall-Pak is made of die-cast aluminum housing and high-impact, heat-resistant polycarbonate lens, efficiently designed to dissipate heat and distribute light evenly.
This all-weather luminaire offers an extended LED lamp life, maintenance-free operation, long-lasting durability, major energy savings, and reduced light pollution, all translating into reliability, ecological sustainability and sizable budget savings.
Standard wall-pack luminaires are notorious for reduced control of light output because of their poor optical configuration, contributing to light pollution, wasted uplight and a shallow light projection. The high-power LEDtronics Wall-Pak’s design achieves a much more efficient illumination coverage — The optical center of the lens is aligned with the lamp source for an even symmetrical distribution of light that redirects light to minimize glare. It effectively sends a wide-focused circular beam of around 85 degrees that spreads 157 degrees vertically and 38 degrees horizontally.
The LEDtronics WWL20-24X2W-XPW-001W floodlight boasts an outstanding color quality, a 6000K pure-white light with 2,777 lumens of brightness. It uses 24 highest-grade CREE XR-E LEDs that meets LM-79/LM-80 requirements, and incorporates a ballast of 0.99 power factor that supplies constant-current power. Its one-piece silicone gasket seals housing and lens frame, locking out moisture and dust, and the all-weather housing is finished with durable, rust- and corrosion-proof architectural bronze.
Because LEDs have no filament, their solid-state design renders them impervious to shock, vibration, frequent switching and environmental extremes. With an average lifespan of more than 50,000 hours (5.7-plus years), white LED bulbs operate more than 20 times longer than the equivalent incandescent bulb! Unlike compact fluorescents, LEDs contain no harmful mercury, and because they do not emit large amounts of heat, UV or infrared light, they protect what they are illuminating. The fact that they run remarkably cool also means they greatly reduce the fire hazard normally associated with the use of incandescent lamps.
The energy-efficient LEDtronics Wall-Pak floodlight provides a controlled, directional light that is perfect for use in parking areas, building entrances, perimeter security lighting; signage illumination and architectural accent; walkways, stairwells and corridors; loading platforms and recreational areas. Since LED lights are 300% more efficient than compact fluorescent lamps, this wall fixture is most suitable for operating on an alternative or renewable energy resource such as solar or wind power.
Additionally, since it produces no harmful ultraviolet or infrared radiation, it reduces light pollution, while its efficient light output makes it compatible with the international “Dark Skies” initiative.
The LEDtronics WWL20-24X2W-XPW-001W LED Wall-Pak luminaire is backed with a 5-year no-fail warranty.
