Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an advertising lamp with a DC to DC wide voltage input. Background Art

[0002] Currently, advertising diffuse light strips and square light inputs need to be powered by AC220V. One way is to directly connect to AC220V power supply, and the other way is to connect to AC220V and then connect a power supply (transformer) to convert AC220V into a fixed DC voltage (the input only supports a fixed voltage value); no matter which power supply method is used, AC220V voltage is required.

[0003] Since many places cannot be connected to AC220, they can only use portable power banks or batteries for power supply. However, the output voltage of portable power banks and batteries fluctuates greatly and is very unstable, and it is very easy to have undervoltage (the light bar becomes dim) or overvoltage (the light bar burns out). For this reason, a DC to DC wide voltage input advertising light is provided. The input is DC to DC, and the output is constant current. It does not need to be connected to AC220V. It is safe and stable and is widely used in mobile light boxes, underground and coal mine light boxes and other scenes. Utility Model Content
