DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0034] The invention discloses a light-emitting module projection angle adjustment structure, which comprises a side cover, an inner cover arranged at the upper end of the side cover and a light-emitting module arranged above the inner cover; a guide rail is arranged on the inner cover, and a running component matching the guide rail is arranged at the bottom of the light-emitting module; the light-emitting module is driven by an adjustment mechanism.

[0035] If the inner cover has an oblong arc surface or an elliptical arc surface, the guide rail is located in the long axis direction or the short axis direction of the oblong arc surface or the elliptical arc surface. For example: the inner cover is a semi-oblong spherical shell, and the oblong arc surface is the inner side surface of the semi-oblong spherical shell. Figure 1 As shown, the guide rail of the light emitting module is arranged on the long axis of the long arc surface. Since the guide rail is adjusted to be longer on the long axis, it has the advantage of adjusting the direction angle. Fig. 9 , the inner cover is also a semi-prolate spherical shell, and the long arc surface is the inner side surface of the semi-prolate spherical shell, such as Figure 1 As shown, the guide rail of the light-emitting module is arranged on the short axis of the long circular arc surface. Since the guide rail is in the short axis direction, it is convenient to set the strip light and can give play to the advantage of adjusting the direction angle of the strip light. Of course, the present invention can also adopt an elliptical arc surface similar to the long circular arc surface, and the guide rail can be arranged in the long axis direction or the short axis direction of the elliptical arc surface. Its arrangement structure is similar to the long circular arc surface, so it is not repeated. In addition, the long circular arc surface or the elliptical arc surface can also be the inner side surface shape of the square inner cover.

[0036] If the inner cover has a circular arc surface, that is, the inner cover is a hemispherical shell, and the circular arc surface is the inner side surface of the hemispherical shell, then the guide rail can be located in the diameter direction of the circular arc surface. In addition, the circular arc surface can also be the inner side surface shape of a square inner cover.

[0037] See also Figure 1-8 , which is a structural schematic diagram of a preferred embodiment of a projection angle adjustment structure of a light-emitting module of the present invention. As shown in the figure: it includes a side cover 3, an inner cover 12 arranged at the upper end of the side cover 3, and a light-emitting module 1 arranged above the inner cover 12; an adjusting screw 2 is provided, and the adjusting screw 2 is connected to one end of a cross-connecting shaft 6 through an umbrella gear set 4, and the other point of the cross-connecting shaft 6 is connected to one end of a transmission shaft 9, and a sliding nut 7 is screwed on the transmission shaft 9; a guide rail 121 is provided on the inner cover 12, and a running part matching the guide rail 121 is provided at the bottom of the light-emitting module 12, and the light-emitting module 1 is connected to the sliding nut 7 through the inner cover 12 through a connecting mechanism.

[0038] When the present invention is used, the bevel gear set 4 is rotated by adjusting the screw 2 clockwise or counterclockwise, thereby driving the transmission shaft 9 to rotate; the sliding nut 7 is driven by the transmission shaft 9 and moves along the direction of the transmission shaft 9, thereby driving the entire light-emitting module 1 connected thereto to move on the guide rail 121 of the inner cover 12 through the running component, thereby achieving the effect of adjusting the angle of the light-emitting module 1. When the light-emitting module 1 reaches the maximum angle or the minimum angle, the running component reaches the end point of the corresponding direction, and the sliding nut 7 also reaches the end point of the rotating shaft 9. The transmission shaft 9 and the sliding nut 7 are threaded structures. Due to the structure in which the sliding nut 7 and the transmission shaft 9 cooperate, when the light-emitting module 1 is adjusted to a suitable angle, the reverse torque will be very large, so that the light-emitting module 1 can effectively stop at the adjusted light-emitting position.

[0039] Please read further Figure 5 In the present invention, the bevel gear set 4 includes a first bevel gear component and a second bevel gear component, the lower end of the adjusting screw 2 is connected to the first bevel gear component, the first bevel gear component is meshed with the second bevel gear component, and the second bevel gear component is connected to one end of the cross connecting shaft 6 through the connecting shaft 13. Therefore, during adjustment, the transmission shaft 9 can not only rotate, but also swing up and down within a certain range (such as: within a 45° range).

[0040] In the present invention, the connecting shaft 13 passes through the side cover 3, and a waterproof silicone ring 14 is provided between the connecting shaft 13 and the side cover 3 to avoid water leakage and other problems caused by the existence of the adjustment mechanism.

[0041] See also Figure 6-8 The connection mechanism in the present invention includes a module bracket 8 and a module bracket connector 5. The module bracket 8 is arranged at the lower end of the light emitting module 1, and the module bracket 8 passes through the inner cover 12 and is connected to the sliding nut 7 through the module bracket connector 5.

[0042] Furthermore, the portion of the module bracket 8 located above the inner cover 12 is provided with a bearing 11, and the bearing 11 acts as a running component and runs on the guide rail 121. The portion of the module bracket 8 located below the inner cover 12 is also provided with a bearing 11, and the bearing 11 acts as a running component and runs on the guide rail 121. There are two bearings 11 located above the inner cover 12, and one bearing 11 located below the inner cover 12, and the three bearings 11 are arranged in an inverted triangle. This structure can make the light-emitting module 1 run more smoothly on the guide rail 121.

[0043] As an inventive point, there is a spring sheet 11 near the bearing 11 below the inner cover 12. This design takes into account that the inner cover 12 (guide rail 121) may be in an irregular arc shape. The spring sheet 11 contacts the inner cover 12 during walking to avoid unstable walking caused by irregular changes in the shape of the inner cover 12 (guide rail 121).

[0044] The light-emitting module projection angle adjustment structure of the present invention is applied to underground lamps.

Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
