Light Emitting Diode

LIGHT EMITTING DIODES Light Emitting Diodes ar electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one mien only. The disco rattling of light emitting diodes we believe was an accident some while around 1907 when a diode in an early radio transmitter was noticed to smooth when in use. In layaboutdescent bulbs use resistance in a strand to impede the flow of electricity, heating up to a degree which emits light.It takes steep amounts of energy to do this and the filament burns out in time and high levels of wasted energy be given off in the form of heat. Quite a green product from a manufacturing and chemic/recyclable point of view. CFL energy savers, fluorescent tubes and many an(prenominal) opposite stuffy lamps use higher frequency alternating online to excite pernicious chemicals to emit light. One 5 foot 1,5meter tube contains enough atomic numb er 80 to contaminate a swimming pool. Billions have been dumped into waste disposal. Heavy coat poisons have a cumulative effect.In the long term these cannot be a fix for the energy crisis we face today. They are poisoning our earth and in like manner us directly through the victuals chain and locally with venting of malign UV. So Energy savers are in the writers opinion very dangerous and should be banned. Aquifers for example may soon be or may already have been rendered unusable. Cape Town for example has piss shortages in summer, plainly our municipal uncontrolled dumps are seance on top of these aquifers. With poison being cumulative up the food chain, we worry about the safety of this water.A lot of our vegetables are grown in this demesne, using this aquifer water. Has this water or these vegetables been tested? light-emitting diode lighting uses less(prenominal) energy than most other lighting sources, with up-to-date commercially getable product generation produ cing 90 or more lumens per watt and doing so with a good cause factor. Initial start up current is not high so production capacity of electricity can be reduced. Led lighting can give the illusion of inseparable light and thus the lit area may not be so obvious as with the predominantly yellow wash from other technologies.However, this warm effect can be created with the appropriate (warm) colour dental plate choice of guide. (Kelvin scale) take lamps can be made to any particularised colour from infra-red to ultra violet for specific requirement. For example, the pure white, 5000-6000K or daylight white 6000-7000k (slightly blue to look at) will greatly enhance consider of detail, help old tired eyes with reading and greatly improves CCTV photographic camera image quality. The limited white light band emitted by light-emitting diode luminaries with very little long wavelength red light content, does not job off glass for example so that CCTV cameras will view inner of ve hicles for example.Visual quality control of food products and manufactured goods is enhanced. Finishing lines for the automotive intentness will clearly show up any blemishes for example. LED useable life span is longer than most other forms of lighting. Actually LED life is governed more by the mains spot supply conversion components that squeeze them. The LED component should be good for 50 000 hours with acceptable issue of output , however the lamp will be limited by the lifespan of the driver which is likely to be 20 to 30 000 hours. The driver converts your stimulus mains Alternating Current to Direct Current.The led itself being a diode, exceeds on low DC voltage. I prefer constant voltage power supplies to drive LEDs as opposed to constant current drivers. Constant current drivers are a little more energy efficient but we have found in practice that they cause the LED to mesh too hot for our liking and in some circumstances dont strike the current fast enough and pop the led. Constant voltage spank mode power supplies have a wide stimulation voltage tolerance, are very efficient and have internal short circuit, temperature and pluck protection circuits with automatic recovery.Conventional low voltage down lights for example in the main use copper wound transformers. Output voltage of transformers follow the input voltage. These type of transformers are around 50% efficient so it takes approx 75watts to guide on a 50watt lamp. This could be replaced by a 6watt LED lamp that would use 7watts pickings the power supply in to account. Power factor would be improved. LEDs run extremely cool relative to conventional lamps so can withal save on air conditioning. A fluorescent or incandescent lamp in a fridge is effectively having a fire at bottom a fridge.High power LEDs do run hotter, but not more or less as hot as metal halide, fluorescent, HPS or incandescent. LED lamps are recyclable and contain no harmful toxins. In addition to this the manufacturing cultivate of this produces less carbon emissions than some other older type of lamps. No hazardous substance disposal procedure required. They will have relatively high recycle value and can achieve Restriction of violent Substances certification. The light output is colour specific, which does not degrade over time. strange most other light sources, they emit very low levels of harmful UV and infra-red rays.For food processing areas, our lamps, if broken, will not contaminate the area and can be made with PVC or poly carbonate covers so no broken glass issues either. (food production plants) LED is available in many guises, so most of your old fittings can be retrofitted with LED to minimize cost and waste. (tubes, bulkheads, downlights etc) LED lighting is directional, so light pollution in to neighbouring areas can be contained. This also allows for much lower power for example in the case of reading lamps. (task lighting).Less confusion blinding shadow creat ures, less attraction and little or no killing of insects. The acres Power team appeals to you to support the growing LED lighting manufacturing which is open to all, unlike the conventional lighting industry which is dominated by wealthy giant corporations who all helped in getting us in to this trouble in the first place. We have been working with LED engineering specifically for 4 historic period now and have identified many top quality reliable products and technologies. These products exceed our expectations and do more than on the dot the job in hand.This technology has leaped in the last few years and continues to move forward. Our dedicated team consists of the founder with 35years owned business get wind in the electronics industry an experienced QS , our marketing relationship manageress with a sub judice degree and our in-training technicians and support staff. EarthPower has quickly become a strong substantially know brand. We may not be the first to offer LED lig hting in South Africa, but we are one of the pioneers and with 4 years dedication, one of the most experienced. Remember, we are all the incumbent custodians of our planet.
