5050 per meter, 60 beads, led band power consumption is about how much watts?
- The electrical parameters of 5050 beads:1, current: 43-46mA (this is the most ideal driving current); maximum use current can not exceed 60mA;2, voltage 2.8-3.6V (transient voltage not more than 5V beads, or damage or serious damage to the LED lamp to repair);3, the ambient temperature -20 degrees Celsius to +40 degrees Celsius (requirements of thermal design of lamps and lanterns do better, LED lamp pin temperature can not exceed 60 degrees);4. If the current is at 14-20mA, the brightness of each 1mA is reduced by 4%;s
LED lamp with frequency converter burn, what's the matter?
- I don't understand. What you mean is that after the LED light is on, the converter is burned. Or after the inverter is turned on, the LED lamp is burned. Whether it is the kind of situation is very normal, because the inverter and the LED lamp are harmonic source, electromagnetic harmonic generation in its work process, is the main cause of the incident, can choose the inverter input special filter, or the input end of special reactors etc. harmonic suppression devices attempt.s
How many meters does the LED flash band need? A controller?
- The controller is used for receiving signals, and the number of meters does not matter. As long as there is sufficient switching power supply to the lamp band, it is possible to meet the power requirements of the parallel light band. Or, in a certain range of load, you can then connect the signal amplifier, you can use a controller to connect the effect of numerous lights!s
LED lights with 0-10V dimming when flashing what reason?
- After the thyristor is switched on, the circuit is not resistive, and the current oscillation occurs due to the capacitance and inductance. When the current oscillates below the thyristor to maintain the current, the thyristor is switched off and then triggered again.s
LED how is the band embedded in the steps?
- The LED lamp band is embedded on the steps: fixed on the steps with double-sided adhesive or glass adhesive or fixed clip.s
How to solve the problem of LED lamp heating problem?
- Specifically, the heat generated by the LED chip comes out of its metal heat sink, first through the solder to the aluminum substrate PCB, and then through the heat conductive glue to the aluminum radiator. Therefore, the LED hotel engineering lamp heat dissipation actually includes the heat conduction and the heat dissipation two parts. However, the size of LED lamp cooling according to power and place, also have different choices.s
Led how much is the price of the lamp?
- LED lamp belt price is according to its quality to evaluate, poor quality a few dollars a meter, good quality of more than ten dollars a meter, recommend the use of photon lighting technology, LED lamp belt, there is always a LED light belt for you.s
How to fit the proper driving power for the LED light?
- 1, LED lights with the initial launch, because the price of space is relatively large, light manufacturers are using current consistency, high brightness LED chip, such chips current is: 0.02A;Later, because of the price of the lamp, the market competition is fierce, many lamps manufacturers use LED chips which are not high brightness and the current is not consistent. The current of this kind of LED chip is 0.011A.2, so we to the most commonly used 5050 chip as an example, a bulb to calculate power:A grain of 5050 beads by 3 chip parallel voltage: 3.2V; 3 parallel chips
