AI Technical Summary
Users need to replace different LEDs to obtain the desired beam angle, which causes inconvenience.
Design an LED lamp that allows switching of the beam angle by setting rotatable first and second working positions on the lamp cover, corresponding to different optical and light-emitting parts respectively. The beam angle can be adjusted by using lenses and light-emitting parts with different frosted/textured designs.
Users can switch the beam angle simply by rotating the lamp cover, which improves ease of use. After switching the beam angle, the emitted light is more uniform and reduces glare.
