Installation-free freely-combined type light-emitting mark

Abstract

The invention relates to the technical field of identification equipment, and discloses an installation-free free combined type light-emitting identification which comprises a main body frame, a rectangular through hole is formed in the top of the main body frame, a supporting plate is fixedly installed in the rectangular through hole, and power supply plates are fixedly installed on the positions, close to the two sides, of the back face of the supporting plate. A stepped power supply method is adopted by a power supply board, and voltage provided by a power supply head is sequentially increased from top to bottom, so that the larger the size of the LED identification device is, the larger the number of jacks spanned by the LED identification device in the vertical direction is, and the larger the voltage provided by the device to the two ends of the LED identification device is; according to the LED identification device, the voltage provided by the LED identification device is a constant value no matter how large the size of the LED identification device is, so that the voltage shared by the LED light beads in the LED identification device is reduced and the brightness is reduced, and the LED identification device can fully ensure that the brightness of the LED light beads in the LED identification device with a relatively large size is kept normal.

Description

technical field [0001] The invention relates to the technical field of identification equipment, in particular to an installation-free and freely combined luminous identification. Background technique [0002] Luminous signs are a very common device in daily life. They can be seen in advertisements, warning signs and installations. Most of today's luminous signs are composed of LED light beads, which have high brightness and long service life. Long and other advantages, the light beads are generally connected in series and energized. An existing installation-free free combination luminous sign adopts a hot-swappable method to realize the function of installation-free. The positive power supply strip and the negative power supply strip are arranged at intervals, and the LED light panels with plugs are respectively connected to the positive power supply strips and the negative power supply strips, so as to directly light up the LED light panels. This way of luminous signs is e...
