Abstract

The invention discloses a portable LED device and a portable LED system. The LED device comprises a first device, a second device, a light-emitting device, a first rotary connecting device and a control device; and the first device and the second device have similar shapes, the shell of the first device is slightly smaller than that of the second device, the first device is connected with the second device through the first rotary connecting device, and the two devices are used in opened, partial opened and closed states. In the closed state, the first device is positioned in the second device; the light-emitting device is fixedly arranged on at least one surface of the first device, and comprises a PCB board, and at least one group of LED light-emitting diodes, a drive control chip and a constant current drive chip which are arranged on the PCB board; and the control device is arranged on the first device and / or the second device. By adopting the proposal, the LED device has a simple structure, is easy to carry and convenient to fold, and is quite suitable to be used by live demonstration and ordinary workers.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to a portable LED device and a portable LED system. Background technique [0002] Due to the characteristics of LED lighting, high light source, no radiation, and low power consumption, LED semiconductor light sources have been widely used in the field of lighting decoration in recent years. However, at present, when many LED technical staff are doing on-site demonstrations of LED screens, because the existing LED screen demonstration devices are relatively large and inconvenient to carry, various troubles will occur when using them, which is not conducive to the use of ordinary people. . Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a foldable LED device which is simple in structure, convenient to carry. [0004] The technical solution of the present in...
