AI Technical Summary
When using the thicker etching effect, the light dispersion effect of existing ring indicators is limited and the brightness is sacrificed, resulting in the need to increase the number of LED lights, increasing the cost and occupying circuit board space.
Using side light emitting LEDs, light enters from the front of the outer convex features of the ring-shaped lampshade, and enters the thin-wall display area with a small angle on the outer arc surface, reducing the number of refractions and improving the uniformity of light dispersion.
By reducing the number of refractions and increasing the light guide distance, the uniformity of light dispersion is improved, and a better display effect is obtained, while simplifying the structure and controlling the cost.

The phrase appears in various places in the description and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0023] Reference is made to the Figures 1-3 , which is a schematic structural diagram of a thin-walled annular indicator light in an embodiment of this application;
[0024] A structure of a thin-walled annular indicator light includes a control board upper cover 1, a control board lower cover 3, a power terminal 4, a control board 5, a knob 2, a light-emitting diode, an annular lamp shade 7, a connecting member 8 and a potentiometer 6;
[0025] The control board upper cover 1 is adapted to the control board lower cover 3;
[0026] There is a space inside the control board upper cover 1 and the control board lower cover 3, and the control board 5 is accommodated in the space;
[0027] The power terminal 4 is provided on the control board 5 and recessed and exposed on the control board lower cover 3;
[0028] The knob 2 is provided on the control board upper cover 1 and is protruded;
[0029] The light-emitting diode is provided on the control board 5;
[0030] One end of the potentiometer 6 is connected to the control board 5, and the other end of the potentiometer 6 is connected to the connecting member 8. The potentiometer 6 is snap-connected to the knob 2 through the connecting member 8. There is a cavity between the connecting member 8 and the knob 2, and the annular lamp shade 7 is accommodated in the cavity.
[0031] The knob 2 includes a knob housing 2 which is arranged in a cylindrical structure and nested on the connecting member 8, the annular lamp shade 7 and the potentiometer 6.
[0032] The annular lamp shade 7 is joined to the control board upper cover 1.
[0033] Specifically, in the past designs, usually a wrapping feature was made from the side. However, due to the too large incoming angle and excessive refraction times, the brightness loss was obvious. The light could be obliquely introduced from the outside, increasing the surface roughness of the light guide member, resulting in obvious brightness loss. It was difficult for the light to spread evenly. There would be a high-brightness spot directly above the LED in appearance, and it would appear darker in other places. If a coarser etched pattern effect was applied to the annular lamp shade 7, the effect of light spreading would be improved but limited, and the brightness was sacrificed. The number of LED lights needed to be increased, and the cost and the circuit board space would be affected.
[0034] Therefore, by using side-emitting LEDs, the light enters from the front of the protruding feature on the outside of the annular lamp shade 7 and enters the thin-walled display area through the small angle of the outer arc surface, greatly lengthening the light guide distance and reducing the number of refractions (the angle is small and closer to a straight line), which better improves the uniformity of light spreading. While obtaining a better display effect, the structure is simplified and the cost is controlled.
[0035] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
