Led (Light emitting diodes) stands for light-emitting diodes. In recent years they have become increasingly led art popular and high quality. LED lighting is an attractive alternative to conventional lighting with incandescent or fluorescent lighting (as in both residential and industrial applications). The reasons for this are that these lights are energy efficient, have a longer life, are small in size, can be controlled by dimmer generate led art relatively little heat, rarely fail, resist shock, work well at low temperatures, their light can be easily focused, contain no toxic elements mercury, unlike other energy efficient lighting. led art A wide variety of Led lighting company offers a "Bull-Lighting" Ltd. and e exclusive distributor led art of branded products "LB Light" for Bulgaria.
Colored and white LEDs LEDs can be red, green, blue or amber. The color of the LED light is determined by the materials used to manufacture the LEDs. For example, the red LED is made of chemical elements of aluminum, gallium and arsenic. White LEDs are created by covering a blue LED with yellow phosphor coating.
LED brightness A single powerful LED diode can produce about 80 lumens of light. For comparison, a standard 60W incandescent bulb produces about 900 lumens. Thus, a LED diode produces only about 1/11-ta the brightness of 60W bulb. To produce enough light LED lighting should contain groups of LEDs. However, LEDs have a bright future because the past 2 years have doubled their lumens.
LED color temperature light sources below 3200 Kelvin led art (3200K), are considered "warm" while those above 4000K are considered "cool." For comparison, a standard light bulb is 2800K. Color temperature of a light source is not related to how much he is hot or how much heat removed. The white LEDs vary in color temperature. This is because most of them are generated by placing the yellow phosphorus on blue LEDs.
LED color recognition Index color recognition (Color rendering index - CRI) is the ability of a light source to reproduce colors more accurately. CRI scale running from 1 (low-pressure sodium) 100 (Sun). Index CRI of 75 is considered good, CRI of 85 is considered very good, CRI 95 is considered excellent, and of course CRI 100 is considered perfect. LEDs in warm white are available from 2009 CRI 80.
LED efficacy As with all light sources, the efficiency of LEDs is measured in lumens / watt (the amount of light produced by one unit of power). Warm white LEDs produce led art between 25-44 lumens per watt while cool white LEDs are more efficient from 47 to 64 lumens led art per watt. For comparison - the ordinary light bulb generates about 10-18 lumens led art per watt, while compact fluorescent bulbs produce 35-60 lumens per watt.
LED power supply LED lights require an electronic power supply that transforms led art electricity from the grid in the appropriate voltage (typically between two and four volt LED-s with high brightness) and current (typically 200 to 1000 mA / mA). Additional power can also include controllers for dimming or color correction.
LED heat is a myth that LEDs do not generate heat. In fact, all light sources produce one and LED lighting is no exception. Thus, it is important for projector lighting to take this into account in order to adequately dissipate the heat that they generate.
LED lifetime LEDs do not burn as ordinary light bulbs. Instead, they gradually reduce the intensity of light, until you stop do not emit enough light to be useful. For an LED is generally believed that it is no longer useful when emit only 70% of the original light. Some LEDs may have a lifetime of more than 100 000 hours, but normally it is only perfect laboratory. In the real ones - most LEDs have a lifespan of up to 60,000 hours.
OLED OLED-off is OLEDs, led art which contains carbon. OLED-s typically manufactured as lightweight and flexible sheets. Today, those LEDs operate at a significantly lower efficiency of inorganic (crystalline) LEDs. They usually generate less light on a particular area than inorganic.
IR and UV radiation white LEDs do not emit infrared radiation, or heat radiation as obinovenite light bulbs. led art Also not present led art ultraviolet radiation (UV rays) having led art luminescent bulbs.
