It's green time!Now is the time for us to not just laugh at how many people we need to change bulbs.Lighting consumes 20% of our home energy and 30% of our work power.Light-LEDs (LEDs) are a 45-year-old technology that provides n thermal outputs with an average of 32 lumens that burn about 50 times as long as ordinary incandescent lamps.According to the Department of Energy, LED lighting can reduce energy consumption in the United States.S.By 2025, energy consumption was reduced by 29%, and in the process our national energy bill was reduced by $125 billion.Recent university research and other advances have helped led replace incandescent lamps in the next five to seven years.In the past few years, the light output of each chip has increased.Once you get more light from the chip, the cost will drop from the light it produces.There are three main lamps: Incandescent Lamp, fluorescent lamp and LED lamp.The LED is a fluorescent bulb or mercury bulb because the incandescent lamp is a fluorescent bulb in terms of energy saving, duration and cost.Light-LEDs are not a new technology (1970 seconds ).The Led has the advantages of small size, long lamp life, low thermal output, energy saving and durability.They also allow for extraordinary design flexibility in discoloration, dimming and distribution by combining these small tuples into the desired shape, color, size and Lumen package.LEDs have evolved from being used as indicator lights and digital displays to a range of innovative and new applications, including accent lights, mission lights, traffic lights, signage, outdoor lighting and lighting --lighting.LEDs have many useful applications that are about to revolutionize many new light sources.The emergence of great visible/White LED awakens new savings in the lighting industry, reduces heating costs and minimizes the possibility of maintenance using this light source.At present, white light emitting diodes can produce enough lumen output to compete with many common light sources.LEDs are solid-state semiconductor devices, and their LED lighting occurs when semiconductor crystals are excited to produce visible light.When the LED unit is powered on, the power supply converts the AC voltage to sufficient DC voltage to illuminate the diode semiconductor crystal.The LED is sealed in a transparent or diffuse plastic lens that can provide an angle distribution of a range of light.Low Led efficiency-voltage, low-Current equipment and efficient light sources.Phillips Lighting notes that 1993 LEDs are needed in 200, while only 18 LEDs today achieve the same performance and are expected to be further reduced to only 10.Progress continues.The effect of up to 100 LPW has been achieved under laboratory conditions.According to Steve Johnson, head of the Lighting Research Group at Lawrence Berkeley National Laboratory, it is not realistic to expect the efficacy of solidsNational sources to achieve 150-In the coming decades, 200 lumens per watt.Currently, a number of manufacturers have provided a range of LED fixtures for replacement of MR16 lamps, display lighting, Bay lighting, underwater lighting, building details and other applications.Designers should carefully consider the necessary lumen packaging, light source brightness, viewing angle and color rendering when considering the use of this technology.Led becomes very attractive.Since the demand for these lights is to save more energy, more supplies are needed to keep us out of the dark.
