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 lamps, a lamp is broken, you can use the short circuit
Led ceiling lamps, a lamp is broken, for the parallel circuit, short circuit breaker can not, can. For a series of circuit systems, a short connection makes the light available. However, due to the circuit in this connection, because the LED is short, the current of this road will become larger, the lights will be brighter, but the life is not long, easy to damage. It's better to change the bad one and change it to a good LED.
Q:LED ceiling lamp, why is it bright after closing the switch?
After the switch is slightly bright, the built-in switch power supply has leakage phenomenon, replace a new power supply
Q:How many tiles are there in the bedroom?
I suggest the landlord to buy 18W-20WLED ceiling lamp, LED ceiling lamp energy-saving than energy-saving lamps, long life, no flash and so on. Or buy advanced intelligent remote control LED ceiling lamp, can mix temperature, brightness (also quite a number of Watts), and also do not have to fear the number of watts to buy inappropriate, and then transferred to their own comfortable number of tiles on it.
Q:About LED ceiling lamp contact touch switch ~!
It should be incompatible. It is better to choose touch switch with relay output. It's always bright, indicating leakage.
Q:what are LED ceiling lamp notes
The installation of the product must be certified professional electrician, do not suggest private disassembly and assembly
Q:Led ceiling lamp is broken. How do you know that the starter is burned or is the LED lamp burning?
LED light does not have a starter, but has a constant current source power supply.Remove the LED light, and then output a resistor with the same power as the LED lamp at the output of the power supply. Then measure the voltage at the two ends of the power supply, which means that the LED light is out of order.
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:how is the LED ceiling lamp lumens
Because of the luminous angle and so on, luminous flux is not the only standard to measure the energy saving of lamps and lanterns. We usually use light distribution and vertical illuminance to measure the substitution ratio between two lamps
Q:My LED ceiling lamp is flashing continuously when I open it. What's the reason?
Nominal 18*1, not LED, see how much no-load voltage.In accordance with the 18*3.3=60V, then the minimum load of 65V in order to properly lit the 18 string of lights. Your new power supply is nominal 40-65V, which is the maximum limit of your power supply. The voltage is low and the light is not normal.As you said, the early stages were normal, and the components of the internal voltage control were faulty. Your actual lamp on the LED lamp may be relatively high voltage (normal LED lamp in 2.8-3.4V).You need to buy the nominal output voltage of 70V (assuming the lamp voltage is 3.4V, the total voltage is 3.4*18=61.2V, +5V=66.2V. This extra 5V is used to adjust the current change after the LED total voltage change, and the constant current 350mA drive power can be substituted.
