Abstract

The present invention discloses an on-site programmable LED drive power. The on-site programmable LED drive power comprises power input lines, power output lines and signal lines. The power input line receives AC (Alternating Current) power input; a power output end receives or outputs electric energy; the signal line transmits communication signals between the LED drive power and other devices; when the LED drive power is in a power mode, the power output line is connected with a power input end of LED lamps; when the LED drive power is in a programming mode, the power output line and the signal line are connected with a programmer; the programmer provides electric energy to a power supply circuit through the power output line; and the programmer carries out signal communication with a signal processing circuit through the signal lines.

Description

Technical field [0001] The invention relates to the technical field of LED driving, in particular to an LED driving power supply capable of field programming. Background technique [0002] LED is a low-voltage unidirectional conductive device driven by current. In actual production and use, it must be provided with a suitable driving voltage and current to ensure normal operation, so it is necessary to provide a driving power source for it. Such as figure 1 As shown, the input of the LED driving power supply 102 is connected to the L and N poles of the alternating current 101, and the output is connected to the LED lamp 103. The LED driving power supply 102 provides the LED lamp 103 with the required DC current and voltage values. [0003] The LED driving power supply provided by the prior art has the following problems: According to the input current and voltage requirements of different LED lamps, special design and testing must be carried out. At the same time, the existing LE...
