Q:What's the average luminous current of an ordinary LED lamp string?: If the lamp light current series is their rated current,

Q:What is the connection distance of the LED light string?Be specific: The connection distance is 15 meters. If the connection distance is exceeded, the LED light string is easy to heat, and the service life of the LED light string will be affected during use

Q:The number of lights in the LED string: Different LED number of LED light band price is different, and this is also to distinguish LED lamp belt price is an important factor.

Q:The top LED lights always burn the bulb in series: If it is a constant current drive, there is a special adjustment element to adjust the current.

Q:Section LED lantern, no controller, can shine principleTwo now reduced brightness string string: When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

Q:What's the price of the LED light string?: The power supply is also the most important factor affecting the price of LED panel light. The power is not good, directly affect the LED panel lamp life. UL power supply performance is relatively stable. The price is about 53 yuan, TUV power supply price is about 33, and other CE power supply.

Q:Led full-color light string and how to control wiring: Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK

Q:The color temperature of LED light string: Refers to a standard blackbody heating, the temperature rises to a certain degree when starting from the color red - Orange - red - white - blue, gradually changed, a light source and the blackbody with the same color, we will at the time of the absolute temperature blackbody called the color temperature of the light source.

Q:What are the power connections for the LED light string?: If you do not want to use a power to control each LED lamp string, can switch power to buy a relatively large power for the total power supply, then put all LED light on the input power (all parallel wire size is not enough, can also extend) unified by the total power switch.

Q: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.
