FAQ

The number of lights in the LED string
15 lights, 30 lights, and 60 lights refer to the LED band. How many LED components are welded per meter length?
Section LED lantern, no controller, can shine principleTwo now reduced brightness string string
LED string:Light emitting diodes, referred to as LED, are made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
Rated voltage of LED lamp string
LED is a light emitting diode. It can be used for AC and DC. Because of the reverse breakdown voltage of LED, it is very voltage. The single LED current can be connected by a ammeter to the inside. If you look at the rated current of LED, you should look at it
What's the price of the LED light string?
Light guide plate and diffuser plateLED panel lamp manufacturer's production line price is probably between 60-80 yuan (12 pieces). The quality of the light guide plate is one of the most important factors determining the quality of the LED panel lamp. The use of high-quality light guide plate can make the finished LED panel light more uniform. No dark spots, ripples and so forth
I want to do a string of LED lights that can use batteries. About 55 or so. The lights are 5MM blue. How can I work? Urgent urgent!!
If it is a general common blue LED working current is 20 mA, voltage of about 2.5V can be lit, the battery power can be used in parallel, the benefits of this connection is one of the damage does not influence the normal operation of other LED. And each LED string to a current limiting resistor, LED protection lamp, prolong life, calculation formula of the resistance for V / 0.02A=: voltage current resistance: 3V, battery powered =3 / 0.02=150. You want to supply 55 LED batteries to work together, the total current is up to 0.02x55=1.1A, i.e. 1AH (ah) capacity of the battery can work 1 hours or so.
Led full-color light string and how to control wiring
5 line DMX512 full color string, 2Po, 2 access, and access control site
The color temperature of LED light string
Generally speaking, the color temperature is not an indicator of the LED band, but many foreign customers will make a special request because of the use of the environment.
Example: if I want to do a 40 head low voltage lamp string, do 10 lights, 1 loop, transformer is 150MA, then how can I calculate the resistance? The grid is 60 Hz of China's power grid! Give a formula, and then count the examples. What is it?! Thank you
If you direct the transformer to the LED lamp power supply, the life of the LED lamp will be affected, far less than the nominal value.
