Problems solved by technology

[0006] The above-mentioned low-voltage DC transmission and the limitation of cable transmission current, these two factors limit the length of the cable from the switching power supply cabinet to the lamp. There is internal resistance, and the loss is large when the current is large, and it cannot supply large current to the lamp. It is often necessary to pull several sets of cables to meet the needs of all the lamps on the cable.

Abstract

The invention discloses a device for improving lamp-controlled direct-current power transmission distance and power transmission power, which comprises a light processor, a low-voltage output switching power supply, a multi-core cable, a lamp, a cable, a direct-current booster and a direct-current step-down transformer. According to the invention, direct-current voltage of a cable is increased, and if the transmission is performed with the same power, the transmission current is small, the high-voltage transmission mode can enable the transmission distance to be farther, and if the transmission current is not changed, the transmission power is also greatly improved, so that more lamps can be controlled; the device for improving the lamp-controlled direct-current power transmission distance and the power transmission power has the advantages that the number (cost) of cables can be greatly reduced for direct-current high-voltage power transmission, the cost of cable laying construction is reduced, the construction time is shortened, a plurality of lamps with the same power are supplied, when the direct-current power transmission and distribution voltage is increased by four times, the current is 1/4 of the original current, a cable with a thin wire diameter can be used for power transmission, and the cost of the cable is reduced.

Description

technical field [0001] The invention relates to a transmission power device, in particular to a device for improving lamp-controlled DC transmission distance and transmission power. Background technique [0002] In the lighting control system, due to the limitation of the size of the lamp or the lamp bead itself, it is impossible to place a large switching power supply inside the lamp cavity, and in addition to safety considerations (AC mains is easy to get an electric shock), it is generally used Low-voltage DC input power supply (such as 12V, 15V, 24V and other low-voltage methods, using low-voltage DC transmission). [0003] Please refer to Figure 1, which is a conventional light control cable (low-voltage power and signal) transmission structure, which consists of a light processor 10, a low-voltage output switching power supply 20, and power and signal cables 30 , lamps and lanterns 40 are combined. [0004] The terminal 11 connects the DC power from the switching pow...
