Distant light source that invented by Thomas Edison, 132 years, LED systems come winning consumers and occupying a prominent role in the Brazilian market of lamps. Valued by the balanced energy consumption, this new technology that converts electrical energy into light inside of a solid crystal material still generates a lot of doubt as to the applicability. To clear up any doubts about the LED Lighting expert and Interior Design and responsible for the training center of the Golden Lamps, Leandro de Barros, analyzes some myths and truths surrounding the theme.
LED light bulb does not heat. MYTH. The LED bulb generates thermal temperature during conversion of electricity into light, but does not play the heat to the environment thanks to the aid of sinks that have the ability to remove them. This is one of the aspects that contribute to increase your lifespan. So it is not possible to place the LED luminaire designed for traditional lamp in that it burns.
The LEDs last forever. MYTH. LED lamps have a long life, but in value over time, like any other artificial light source. This light is provided for depreciation by testing for a long period of time, in order to determine when a specific percentage of light is lost. Some factors contributing to the degradation of the luminous flux, as changes in temperature, variation of currents in the fountain and the efficiency of refrigeration systems. When the LED system does not fail, the depreciation of the luminous flux is an important factor to establish the lifetime of the product.
The LEDs do not burn. TRUTH. The product does not burn, but loses the light intensity with time. The LEDs of good specification must 20000 to 50000 hours lifespan, with a loss of 30% luminous flux. The diode lasts, but the components last less. The heat causes degradation of phosphorus in white LEDs causing a depreciation of the brightness and color temperature variation.
With LED Systems are very expensive.TRUTH. However, the return on investment in energy saving and maintenance is fast, there are situations in which the return of this investment can happen in less than a year. Moreover, it should be taken into consideration that the value of the system is already cheaper than a year ago, and the trend is this value further reduce.
There is no LED light bulb in tube. MYTH. Today there are models with similar formats to the tubular lamps with LED technology.
The line PAIR LED replaces some compact fluorescent lamp model. MYTH. The PAIR LED line exists to replace the halogen PAR (retrofit).
All LED system needs power supply. TRUTH. All LED system needs driver, subject to systems plug-in, which now come with built-in driver. The function of the driver is to assist in firing and LED drive, i.e. is a species of power supply, only with low voltages of 12 and 24V. But be careful, each LED system has a supported driver, i.e. with appropriate voltage and current to the system.
The LED can be installed in a common socket. TRUTH. Various models can be installed in standard screw base E27 Brazilian.
The LED can be dimerizado. TRUTH. But not all models available on the market allow the light intensity adjustment.
The LED can be applied anywhere. MYTH. In our days, not always the LED is the best solution. There are technical issues to be considered: Its Color rendering index (CRI) is not high, is between 70 and 80. So the LED is not applicable to all. It’s not ideal, for example, in highlights in clothing store because it has good color fidelity. To decorative lighting he is unbeatable, because it has saturated colors, variety of opening angle and some models allow you to control the colors.
