After receiving the aforementioned working power, the aforementioned execution unit 12 transmits the generated LED-ID signal to the aforementioned register unit 13. The aforementioned register unit 13 then performs format conversion and buffering on the LED-ID signal, and transmits the format-converted and buffered LED-ID signal to the aforementioned plurality of dual-color temperature LED lamp cores and modulation drive circuit units 2 through the aforementioned connection unit 14.

[0076] Furthermore, in order to activate the guiding device based on dual-color temperature LED array lighting fixtures, such as Figure 3 As shown, Figure 3This is a circuit diagram of the LED-ID information pre-setting main control circuit board in the second embodiment of the guiding device based on dual-color temperature LED array lamps proposed in this utility model. In this embodiment, the above-mentioned starting unit includes: DC power socket J1, fuse F, self-locking switch SW, first resistor R1, LED indicator D, and linear regulator WY;

[0077] It should be noted that the aforementioned DC power socket J1 can be any DC power input used to provide repeatedly pluggable, fixed-polarity, and externally disconnectable / internal-reversible power supply to guiding equipment based on dual-color-temperature LED array lighting fixtures.

The third end of the aforementioned DC power socket J1 is connected to the first end of the aforementioned self-locking switch SW. The second end of the aforementioned fuse F is grounded. The second end of the aforementioned self-locking switch SW is connected to the first end of the aforementioned first resistor R1 and the first end of the aforementioned linear regulator WY.

[0101] It should be noted that the aforementioned external power supply can be a 5V external power supply. This means that the external power supply can be obtained from the 12V to 5V converter of the motherboard power supply, or it can be obtained by connecting to an external 5V power supply.

[0102] It should also be emphasized that, in this embodiment, the first voltage regulator chip U2 and the second voltage regulator chip U3 can each supply power to the first transistor Q1 and the second transistor Q2 independently. Since the lamp core includes two LED beads, and only one LED bead can be lit at a time, in certain specific situations, using only one voltage regulator chip to supply power to both transistors at the same time can save components and reduce costs.

The LED-ID signal also travels from the second three-terminal connector J3 through the first voltage regulator chip U2 and the fourth resistor R4 to the lamp core 22. The LED-ID signal travels from the second three-terminal connector J3 through the second voltage regulator chip U3 and the fifth resistor R5 to the lamp core 22. The LED-ID signal travels from the second three-terminal connector J3 through the inverter 211, the third resistor R3 and the second transistor Q2 to the lamp core 22.
