What are the terms of the LED power supply for lighting?

Introduction: LED drive power supply is to convert the power supply to a specific voltage and current to drive the LED light power converter. The following LED power manufacturers to sort out the specific terms on the LED driver power supply, so that we can more easily understand the LED driver power supply.

What are the terms of the LED power supply for lighting?

1, LED driver for lighting lightingLEDDriver

LED control and power supply device for lighting.

2, rated rating

The specific value of the drive under the specified operating conditions, which is specified in this specification or by the manufacturer or seller.

3, rated input voltage inputvoltagerating

The specific input voltage of the driver under the specified operating conditions, which is specified in this specification or by the manufacturer or seller. This specification takes 220V.

4, rated output power outputpowerrating

The specific output power of the drive under specified operating conditions, which is specified in this specification or specified by the manufacturer or seller.

5, start time turnONtime

The AC power supply is connected to a constant current output rated current (or constant voltage output rated voltage) of 90% of the established time period.

6, overshoot amplitude overshoot

The phenomenon that the output DC voltage or current exceeds the stable value caused by the transient change of a certain amount of influence. Overshoot amplitude is the maximum amplitude of the output current or deviation from the stable value.

7, load regulation loadSTability

The relative change of the output current (or the output voltage of the constant voltage driver) caused by the change of the load due to the change of load.

8, input voltage adjustment rate voltagestability

The relative variation of the output current of the constant current driver (or the output voltage of the constant voltage driver) is caused by the change of the input voltage when all the other variables remain unchanged.

9, output voltage ripple and noise OutputRipple&Noise

The peak value of the AC component included in the output DC voltage.

10, the input current inputinrushcurrent

When the power is turned on, the maximum instantaneous current value of the AC input circuit.

11, the highest shell temperature maximumcasetemperaturetc

Maximum surface temperature of the housing when the driver is in operation.

12, the maximum ambient temperature maximumambienttemperature

Maximum ambient temperature to ensure normal operation of the driver.

13, creepage distance creepagedistance

The shortest path between the two conductive parts along the insulating surface or between the conductive part and the device protection interface.

14, electrical gap ELectricalclearance

The shortest distance between two conductive parts or between the conductive part and the protective interface.

15, dielectric strength dielectricstrength

Dielectric strength refers to the medium voltage, when the voltage exceeds a certain limit, the dielectric current increases rapidly, the dielectric properties of the dielectric is damaged, this phenomenon is called dielectric breakdown, then the voltage is called the breakdown voltage, the corresponding electric field strength is called dielectric strength.

16, double insulation doubleinsulation

Insulation consisting of basic insulation and additional insulation.

17, strengthen insulation reinforcedinsulation

A single insulation structure, which provides protection against electric shock in the event of a double insulation. Note: the "insulation structure" of this predicate does not refer to the insulation must be a homogeneous whole. The insulation structure can be composed of several insulating layers which cannot be tested separately, such as additional insulation or basic insulation.

18, flashover flashover

The destructive discharge of a gas or liquid medium along an insulating surface at high voltage. The discharge voltage is called the flashover voltage. After flashover, the voltage between the electrodes decreases rapidly to zero or close to zero. The spark or arc in the flashover channel causes the surface of the insulation to overheat and cause damage to the surface. Flashover along insulator surface.
