Q:LED living room ceiling lamp has sectional dimming and stepless dimming, which is good? What kind of power saving and low energy consumption?
With stepless change have different advantages and disadvantages: fewer people do not have the place closed - sub, but often one easy bad. Although stepless adjustment is the whole electricity, can not take care of a key, but work in LED than rated current under the condition of small life will multiply long, the total life is much longer than the top, like some more light flashlight, only a part of dark light, finally is the bad, and the adjusting method is not a simple resistor in series to reduce the current, so the entire dimming is than full light electricity, similar in principle, with the dimming incandescent lamp so that single from power considerations are similar, but from life, stepless was stronger than the segment.
Q:About LED ceiling lamp contact touch switch ~!
Your touch switch should be controlled by silicon light, and your LED dome light is just ordinary power supply, not dimming power, so it will flash when touching light
Q:How does LED ceiling light distinguish between good and bad?
1 see, LED ceiling lamp appearance, check whether the appearance of defects, the seal is intact, whether there is leakage phenomenon.2, look at the lampshade material, now LED ceiling lamp generally use acrylic cover, rarely use glass, acrylic face mask light transmittance is strong, and unlike glass chimney is so fragile, more light and safe.3, look at the beads, beads is the core part of ceiling lamps, domestic beads, Taiwan has imported and imported beads, domestic cheap, but the quality is not good, some of the LED lamp manufacturers in order to save costs, reduce the price of LED lamp, made of beads, the quality is certainly not guaranteed, Taiwan the relative price of domestic imports of beads beads will be more expensive, but the quality can be guaranteed, the price ratio is relatively cost-effective. Better quality beads imported from abroad, but the price is higher, customer choices. Therefore, customers in the choice of LED lamps, we can not just look at the price, we should choose from the overall cost performance.4, look at the LED ceiling lamp chassis, chassis is best to choose alloy chassis, good heat dissipation, and corrosion resistance.
Q:15 square meters of living with the Duodawa number LED ceiling lamps
Home improvement, if it is led lamps, then 1w/ square meters, that is, the living room 25 flat, choose 25w.But the bedroom can be a little smaller, hit a twenty percent off, or 15 flat, choose 12w.Similarly, the kitchen enlarged 1.1 times, the toilet 0.9 times, the study 2 times.If it is energy-saving fluorescent lamp, then you need to take 3 times.If it's an incandescent lamp, it will take 7.5 times.That is, led: energy-saving fluorescent lamp: incandescent lamp =1:3:7.5.The lamp light absorbing light shade effect, etc. Considering the effect, may need to take the numerical calculation of expansion coefficient of 1.1~1.5.
Q:LED ceiling lamp, thunder will burn it?
Burnt.Leakage protection switch normal, is produced by current flowing through the coil when the leakage magnetic field, electromagnetic induced protection action to cut off the circuit and electrical suffered lightning damage more often because of high voltage caused by lightning.Ordinary leakage protector even closed indoor fundamentally incapable of action, the city power switch into the household, when the voltage is high enough for a lightning invasion of the grid, still can switch between the electrode breakdown and air gap formation pathways, even in the indoor circuit on electric appliances and equipment (think of electrostatic cloud layer on the distance of ground objects so far, lightning can still breakdown discharge, you know how high the lightning voltage).So, the safest way to make lightning weather is to unplug all appliances that need not or may not be used for the time being.
Q:Introduction to the working principle of LED ceiling lamp ballast
Single ballast connection method is divided into:1, do not distinguish between zero FireWire line (ie: FireWire, zero line arbitrary connection).2, distinguish the zero line methodFire line is generally red or white line, zero line is generally black line.
Q:What are the advantages and disadvantages of LED ceiling lamp?
High luminous efficiency, low power consumption, long service life, easy control, free maintenance, safety and environmental protection, is a new generation of cold light, than the tube shaped energy-saving lamp energy saving, high brightness, light cast light, good performance, wide range of operating voltage, the light source through the built-in microcomputer controller, can realize LED seven kinds of color change, color soft, colorful, rich and colorful, low loss, low energy consumption, green environmental protection.
Q:how is the LED ceiling lamp lumens
All theory, laboratory data, it is the actual use effect, good chip LED lamps, the pure three colors illuminate the effect with 2 times its power (it is good lamp) almost ceiling effect. That is to say, the 5W of LED is almost the same as the 10W tube.
Q:Led ceiling lamp is broken. How do you know that the starter is burned or is the LED lamp burning?
Use a good LED light to change the original one, turn on the power, and if it doesn't light, the starter is broken
Q:what are LED ceiling lamp notes
Daily cleaning method for dimming LED ceiling lamps as the ceiling lamps hanging in height, lampshade, lamp is easy to break, so, remove the cap, as far as possible with two people; before the demolition, turn off the power first, do not use wet cloth to scrub the holder, prevent leakage. Ceiling lamps lampshade clean ceiling lamps according to the different materials also have shade, different cleaning methods: cloth shade, first with a small vacuum cleaner dust off the surface, then pour some detergent scrub; if the inside is a paper lampshade material, direct use of detergents should be avoided to prevent breakage, wipe with dry cloth it can be cleaned with a soft cloth dipped in toothpaste; frosted glass lampshade, convex and concave dirt with soft cloth wrapped with a toothpick.
