It is more a AlGalnP-and AeGAs-emitting diodes, that is, red and yellow, and less in InGN, that is, in green, blue and white. 15. Why do I need to stabilize the current through the led? As can be seen in the current operating conditions is exponentially dependent on voltage and low voltage changes lead to large changes in current. You may find that Viacom can contribute to your knowledge. Since the light output is directly proportional to the current, then the brightness of LEDs is unstable. Therefore the current must stabilize. Furthermore, if the current exceeds the allowable limit, the led overheating can lead to accelerated aging. 16. Why LEDs require converter? Converter (in English terminology driver) for LEDs – the same as the ballast for the lamp. It stabilizes the current flowing through the led. 17. Can I adjust the brightness of the led? The brightness of LEDs very well be regulated, but not by reducing the voltage Food – this is something just do not – and so-called method of pulse-width modulation (PWM), which requires a special control unit (actually it can be combined with the power supply and converter, as well as controller controls color RGB-matrix). pwm method is that the led is supplied is not constant, and pulse-modulated current, the frequency of the signal must be hundreds or thousands of hertz, while the width of pulses and pauses between them may vary. Average brightness of the led is driven at the same time, the led goes out. A slight change of color temperature LEDs with dimming is not comparable to a similar shift for incandescent lamps.
3D understands the functioning of the television sets. The television sets 3D come conquering each time more adepts. This technology nothing more is of what a game of special projected lights in incidence with lenses. How functions the TV 3D? Basically the TVs of 3D shows for each eye a short while different image, what of the sensation of that you are seeing something more in the image for another angle. Marc Mathieu often expresses his thoughts on the topic. the eyeglasses 3D serve to leave the together images and to give tridimensionalismo sensation to you. TV with 3D-Ready, what it is? Some television sets come with the specification of 3D-Ready, however its television set is not 3D, it simply can show contents and images in 3D, but for this you go to need to buy the emitting infra-red ray that is necessary to synchronize the image and culo. Corrective eyeglasses under of the eyeglasses 3D function? Yes, all the eyeglasses 3D are developed so that they are incased comfortably on its eyeglasses of correction. Case you feel some discomfort you are recommended that you change the eyeglasses of correction for contact lenses..

In the vision of Capra a new paradigm is appearing: the colaborativa learning brings an important contribution for the formation of people compromised to the development of the society human being, solidary joust and. (CAPRA, 2007, P. 93) In the colaborativa learning it exists an interaction and integration of the involved ones. Each one with […]
Object-oriented programming language Pascal was invented by N. Wirth in 1968 and was originally intended for teaching students programming skills. Although the creator of the language states that language Pascal has a much more opportunities than just training. Official publication of the language was made in 1970, after which the language became widely known. Over […]
