led Downlight Is the application of new LED lighting improvements developed on the basis of the traditional lamp products, comparison with the traditional downlight LED downlight Has the following advantages: energy saving, low-carbon, longevity, color is good, fast response. LED downlight design more beautiful light, can reach to maintain the overall architectural unity and perfect installation, does not destroy the lighting setup, light hidden architectural interior light source is not exposed, no glare, the human visual effects gentle, even.
led Downlight Features: maintain the overall architectural unity and perfect, and does not destroy the lighting setup, light hidden architectural interior light source is not exposed, no glare, the human visual effects gentle, even.
LED Downlight Energy conservation: the same brightness power consumption for the general energy-saving lamps 1/4 .
LED Downlight Section Environmental protection: no mercury and other harmful substances, environmental pollution (experts pointed out: a fluorescent lamps containing mercury can contaminate 180 tons of water).
LED Downlight Section Economy: because saving can reduce electricity costs, a year and a half recoverable lighting costs a household electricity savings of tens of dollars a month.
LED Downlight Section Low Carbon: the power to reduce carbon emissions equivalent.
LED Downlight Section longevity: LED lamp life of 50,000 hours, six hours a day, is 20 years of life.
1, Energy: White LED Downlight The energy consumption of incandescent lamp 1/10, energy-saving lamps 1/4, LED theoretical life of over 100,000 hours, for ordinary home lighting can be described as 'once and for all'.
2, You can work at high speed: energy-saving lamps or if you frequently start off the filament will be black soon damage ,but LED Downlight will not.
3, Solid package, are cold-light source type. So it is very easy to transport and install, can be installed in any micro-and closed equipment, not afraid of vibration, the main consideration is the heat.
4, LED lighting Technology is the rapid progress, its luminous efficiency is astounding breakthrough, prices have also been reduced. A white LED lamps into the family era is rapidly approaching.
5 , Environmental protection, no mercury (Hg) and other environmentally harmful substances, will not cause damage to the environment. LED lamp assembly parts can be very easy disassembly, recycling manufacturers can not be recovered by others. LED does not contain infrared, ultraviolet, so the insects do not move .
6, Fast response: LED Downlight Day fast response, completely eliminating the traditional high pressure sodium lamp starter long process shortcomings.
Summary: Obviously, as long as LED lighting With the continuous improvement of costs and reduce led technology. Energy-saving lamps and incandescent lamps will certainly be replaced by LED lamps. Current national energy-saving lighting and more attention to environmental issues, has been vigorously promoting the use of LED lighting The particular government street reconstruction project is the first LED lights, LED lights visible on the specified starting LED lighting Alternative energy-saving lamps, incandescent momentum.
1` led Downlight According to size, it can be divided into 2-inch, 2.5-inch, 3-inch to 8-inch, general downlight size relationship between the two figures, an outer diameter, a size that is opening, that is, when the ceiling construction dig the holes.
2` Press led Downlight Lamp beads used classification, can be divided into high-power lamp beads, low-power integrated lamp beads lamp beads and three.
3` led Downlight General fog mask, but matte effect is to reduce the cost of light, so there are some downlights made transparent cover .
led Downlight how to choose:
select led Downlight Mainly from the following three aspects to consider:
1 See the lighting used radiator : Cooling speed determines the whole lamp light failure degree and life, high temperature heat sink is too small will accumulate inside the lamp bead work long hours under high temperature, the light fades quickly, life is very short Division I used. radiator shell are thick material, in order to ensure heat dissipation.
2 See lamps drive Power supply (commonly known as the transformer): Transformer also determines the quality of life of the whole lamp, lamp beads used for more than 50,000 hours no problem, but if the transformer bad words, whole bright lights can not afford it. The transformer used in electronic components, the design determines the efficiency of the transformer , power factor, stability, temperature rise, service life. Our drivers are used in a wide voltage drive, the output current and voltage stability.
3 Learn lamp beads brand and packaging : Lamp bead quality decides the lamp lighting effects, a key factor in quality lamp beads, cooling and other packaging technology affect lamp bead chip has the United States chip, Taiwan chip, domestic chip, etc. Different brand, price difference is bigger, lighting effects are also big differences. . Our used light sources are all well-known international brands.
