Abstract

The invention discloses an LED display lamp with the adjustable lighting area. The LED display lamp includes an LED lamp base, a hose and a lamp holder, the bottom end of the hose is connected with the LED lamp base, the top end of the hose is connected with the lamp holder, a stabilizing box is arranged on the lamp holder, two fixing plates are arranged on the surface of the left side of the stabilizing box, a rotating rod is arranged between the two fixing plates, rotating columns are arranged at the front end and the rear end of the rotating rod correspondingly, a moving column in the widthdirection is arranged on the lower side of the stabilizing box, limiting columns are arranged at the front end and the rear end of the moving column correspondingly, the rotating rod is provided witha shielding cloth, and the moving column is internally and symmetrically provided with a first moving block and a first spring; and the moving column is moved, the shielding cloth is pulled, the shielding cloth shields the lighting surface of the lamp holder, the lighting area is reduced, a wire connected to the LED lamp base is wound around the outer side of a winding column, an overturning cover is rotated and matched with the upper surface of a limiting box, a limiting rod is embedded into a limiting hole to stabilize the overturning cover, and thus the wire cannot leak out of the limitingbox due to looseness.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to an LED display lamp with an adjustable illuminated area. Background technique [0002] LED, light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, and the other end is the negative pole. , the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. LED lights have the advantages of energy saving, longevity, and environmental protection, but LED lights cannot moderately adjust the lighting area and lighting range, and LED lights are not in use. Its wires can be accidentally pulled and are easily damaged. [0003] The lighting area and lighting range of existing LED lights are difficult to adjust. Therefore...
