Title:
ANTI-IMPACT AND AUTOMATIC FLOW-SPLITTING LED UNDERWATER LAMP
Document Type and Number:
WIPO Patent Application WO/2022/141357
Kind Code:
A1
Abstract:
An anti-impact and automatic flow-splitting LED underwater lamp, comprising an LED lamp (1), an anti-impact structure sleeved on the LED lamp (1) and rotating about same, and a mounting base (4) for fixing the LED lamp (1). The anti-impact structure comprises a flow splitting structure (2). The flow splitting structure (2) comprises a sleeve (21) sleeved on the LED lamp (1) and a plurality of special-shaped flow guide pieces (22) disposed on the sleeve (21). The plurality of special-shaped flow guide pieces (22) are uniformly arranged on the outer wall of the sleeve (21) in an array using an axis of the sleeve (21) as a polar axis. The special-shaped flow guide pieces (22) are arranged in the axial direction of the sleeve (21). Inner recessed surfaces (221) are provided on one side of the special-shaped flow guide piece (22), and outer protruding surfaces (222) are provided on the other side of the special-shaped flow guide piece (22). The sum of the impact force borne by all the inner recessed surfaces (221) of the special-shaped flow guide piece (22) is greater than the sum of the impact force borne by all the outer protruding surfaces (222) to push the flow splitting structure (2) to rotate, thereby changing the direction of the water flow impact so as to realize automatic flow splitting. According to the anti-impact and automatic flow-splitting LED underwater lamp, the impact of water flow on the LED deepwater lamp is reduced, the service life of the LED deepwater lamp is prolonged, the maintenance and replacement are convenient, rapid, and simple, and the influence of aquatic plants on the normal illumination of the LED deepwater lamp is reduced.
