Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of LED lamps, in particular to a rotating LED ring lamp based on the DMX512 data protocol. Background Art
[0002] The principle of LED light emission is based on the potential barrier formed by the terminal voltage of the PN junction. When a forward bias voltage is applied, the potential barrier drops, causing the majority carriers in the P and N regions to diffuse toward each other, thereby emitting light. Existing LED lamps highlight different styles of LED lamps through the design of lamp housings with different shapes. By combining lights of different colored LEDs and connecting to a lighting controller, they output lighting effects based on the DMX512 data protocol. "Light walls" arranged in light strips or matrices, under the control of the DMX512 data protocol, can produce effects such as flashing and flowing lights. Existing LED ring lights are generally used only for general lighting. A few incorporate DMX512 data protocol control, but these LED ring lights are fixed and lack the ability to simultaneously output lighting effects and adjust the position of the LED ring lights. Utility Model Content

[0005] Furthermore, the LED ring light includes a ring light shell, an LED light strip, and a ring light cover. A groove is provided along the outer wall of the ring light shell. The LED light strip is pasted in the groove to form a circular light strip. The ring light cover is snap-connected to the ring light shell.
