LED Downlight Is the application of new type LED lighting products developed on the basis of traditional downlight with traditional contrast LED downlight downlight Provides the following benefits: energy-efficient, low-carbon, long life, good color, high response speed. LED down light design more beautiful and light, installation can keep the overall architectural unity and perfect, without damaging the lighting settings, light source hidden architectural Interior, light exposure, no glare, people's Visual effects soft, uniform.
LED Downlight Feature: maintain the architectural integration and perfection, without damaging the lighting settings, light source hidden architectural Interior, light exposure, no glare, people's Visual effects soft, uniform.
LED tube lamp Energy efficiency: the same brightness power to ordinary energy-saving lamp 1/4 .
LED tube lamp Environmental protection: do not contain mercury and other harmful substances, no pollution to the environment. (Experts say: a fluorescent lamps containing mercury pollution 180 tons of water).
LED tube lamp Economy: power reduces electricity costs 1.5 year may recover the cost of lamps. A family can save electricity to dozens of Yuan a month.
LED tube lamp Low carbon: save electricity equivalent to reducing carbon emissions.
LED tube lamp Longevity: LED lamp life expectancy of 50,000 hours, six hours a day, 20 years of life.
1, Energy-saving: white LED tube lamp Energy consumption for incandescent lamps only 1/10, 1/4 of energy-saving lamps, LED the theoretical life of over 100,000 hours of normal household lighting ' once and for all.
2, Can work at high speed: energy saving lamps if filament will be blackened for startup or shutdown of frequently soon damaged But LED tube lamp Will not.
3, Solid package belongs to the cold light source type. So it's very easy to transport and install, devices which can be installed in any small and closed, not afraid of vibration, the main consideration is heat dissipation.
4, LED lamps Technology is rapidly changing in progress, its luminous efficiency is amazing breakthrough, the price has been reduced. A white-light LED lighting into the home is rapidly coming of age.
5 Environmental protection, does not contain mercury (Hg) and other environmentally harmful substances, does not cause damage to the environment. LED lamp Assembly parts can be very easy to disassemble without the manufacturers recycling can be reclaimed by others. LED does not contain an infrared, ultraviolet radiation, so there's no bug.
6, Fast response: LED tube lamp Fast response, total elimination of the shortcomings of traditional process of high pressure sodium lamp Starter long.
Summary: it is clear that as long as the LED lamps As led technology continues to improve and reduce the cost. Energy-saving lamps and incandescent lamps will be replaced with LED lamps. Current national energy-saving lighting and environmental issues more seriously, has promoted the use LED lamps ... Especially reconstruction Street project is first and foremost the Government LED lights, indicating LED Street lamp visible LED lamps Alternative energy-saving lamps, incandescent momentum.
1` LED Downlight By size, can be divided into 2-inch, 2.5-inch, 3-inch to 8-inch, General downlight is the relationship between two numbers, one is the Od, is a hole size, excavated during construction of the ceiling which is size.
2' press LED Downlight Led by classification, can be divided into high power led, power led and integrated led three.
3` LED Downlight Mask is generally fog, but fog is at the cost of reduced efficiency, therefore, has also made transparent part downlight cover .
LED Downlight How to select:
Choose LED Downlight In the following three aspects to consider:
1 See lamp radiator : Thermal determines the whole lamp lumen maintenance and life inside the radiator is too small can cause heat build-up in the light. Working lights at high temperatures for a long time, light fades quickly, have a short life. Division I the heat sinks are thick with shell material, to ensure the heat.
2 And see lamps Drive Power supply (commonly known as transformers): Lamp life depend on quality of transformer, led more than 50,000 hours of use is no problem, but the transformer if it breaks, the whole lamp will light up. Transformers used in electronic components, design determines the efficiency of transformers, power factor, stability, temperature rise, life. Our drive for wide voltage, output current and voltage stability.
3 About led branding and packaging : The LED lamp quality light lighting effect, package process affect the LED lamp quality, cooling, and other key factors. Led chips United States chip, Taiwan chip, homemade chips. Different brands, price differences, and also has great lighting effects. Our light is an internationally renowned brand of light.
