Detailed ways

In order to facilitate the understanding of the present application, the LED street lamp will be described in a more comprehensive manner with reference to the relevant drawings. Some examples of LED street lights are shown in the drawings. However, LED street lights can be implemented in many different forms, and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the LED street lamp more thorough and comprehensive.

It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also be present. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only, and are not meant to be the only embodiments.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of this application. The terminology used in the description of the LED street lamp herein is only for the purpose of describing specific embodiments, and is not intended to limit the application. The term "and/or" as used herein includes any and all combinations of one or more related listed items.

As shown in FIG. 1, this embodiment discloses an LED street lamp. The LED street lamp includes a lamp body 1 and a light sensing controller installed on the lamp body 1. The light sensing controller includes a light controller 2, a light control socket 3 and a sealing ring. The sealing ring includes a sealing ring body 41, the middle part of the sealing ring body 41 has a mounting hole 40 for installing the light control socket 3, and the sealing ring body 41 has opposite lower end surfaces and upper end surfaces. When installing, first put the sealing ring body 41 on the outside of the light control socket 3, the sealing ring body 41 wraps the light control socket 3, and the lower end of the light control socket 3 extends beyond the lower end surface of the sealing ring body 41. Then the light control socket 3 and the sealing ring are integrally installed on the lamp body 1, and finally the light control 2 is installed on the light control socket 3. The light control 2 is also sleeved outside the sealing ring body 41 and can seal the sealing ring The upper end surface of the body. The light controller 2 can rotate 360 degrees.

As shown in Figures 1 and 2, the outer periphery of the sealing ring body 41 is provided with three annular waterproof skirts 42.

It should be noted that in other embodiments, the ribs 43 may be further provided with more, for example, three or more than three.

In this embodiment, the cross-sectional shape of the annular rib 43 is a triangle. The rib 43 can be deformed to a certain extent after installation. It should be noted that in other embodiments, the cross-section of the ring-shaped rib 43 may also have various shapes such as a circle, an arc, or a square.

In some embodiments, the annular waterproof skirt 42 may be an annular protrusion extending radially outward from the outer peripheral wall of the seal ring body. As can be seen from Figures 1 and 3, the mounting hole 40 includes a first hole section communicating with the upper end surface and a second hole section communicating with the lower end surface. The diameter of the first hole section is larger than the diameter of the second hole section, thereby A shoulder 46 is formed between the first hole section and the second hole section. The shoulder 46 is provided with a notch 44 for the screw 5 to pass through. In addition, the light hole socket 3 includes a ring seat 30 that can rest on the shoulder 46, and the ring seat 30 is provided with a fastener fixing hole for the screw 5 to pass through. Opposite the notch 44.

In some embodiments, the lamp body is further provided with an annular boss 10, the lower end surface of the sealing ring body 41 is arranged on the annular boss 10, and the lower end of the light hole socket 3 passes through the central hole of the ring boss 10. Extend into the lamp body 1. The annular boss 10 is also correspondingly provided with a threaded hole 101 for mounting the screw 5.

In this embodiment, the light sensor includes two screws 5, the shoulder 46 of the sealing ring body 41 is provided with two notches 44, correspondingly, the ring seat 30 of the light control socket 3 is also provided with two tightening Fixing holes for the firmware, the lamp body 1 is provided with two threaded holes 101, and the screws 5 are screwed into the lamp body 1 after passing through the fastener fixing holes on the light control socket 3 and the notches 44 on the sealing ring body 41 in turn The upper threaded hole 101 realizes the installation and fixation of the entire assembly.

The above-mentioned embodiments only express several implementation manners of the present application, and their description is relatively specific and detailed, but they should not be interpreted as a limitation on the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can be made, and these all fall within the protection scope of this application.
