[0002] The large street lamp is also known as a floor-standing eye protection lamp, a vertical eye protection lamp, or a sunlight lamp. Because of its tall and square shape, it is very similar to a street lamp, so it is called a "large street lamp". Compared with an ordinary table lamp, the large street lamp has a larger lighting range and better lighting uniformity.

[0003] Most of the existing large street lamps are composed of a relatively large rectangular lamp head, a base, and a lamp post. Among them, the rectangular lamp head is provided with two light sources, a surface light source and a backlight source. The surface light source is used for illuminating the desktop, and the backlight source is used for ambient light illumination, with a relatively high luminous flux and illumination.

[0004] Among them, due to the relatively large overall volume of the large street lamp, during logistics transportation, it is mostly packaged and transported in three parts: the lamp head, the base, and the lamp post. Users need to install it by themselves. The lamp post and the lamp head of the existing large street lamp are installed with the flat end faces aligned. During installation, it is necessary to first place the lamp post on a suitable height and try to keep it parallel to the ground. Then, hold the lamp head vertically and fit it against the end face of the lamp post, and align the 4 connecting holes and connect them with bolts. The entire installation process is mostly in a low squatting position, making the installation of the overall lighting fixture relatively laborious and inconvenient. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] The following further describes the present utility model with reference to embodiments.

[0033] Embodiment:

[0034] The present utility model provides a large street lamp. This solution mainly improves the connection structure design between the lamp head 10 and the lamp post 20 to enhance the portability of lamp body assembly and reduce the difficulty for users to install the lamp.

[0035] Refer to Figures 1-6 , the main structure of the product includes a lamp post 20, which is a hollow rod body with openings at both ends. In this embodiment, the lamp post 20 is a hollow aluminum alloy tube with a rectangular cross-section. The internal screw posts 21 and reinforcing ribs 23 are integrally formed with the rod body.

[0036] It further includes a lamp head 10 for emitting light. The lamp head 10 includes a lamp frame 15 and a back plate 16. Surface light sources 11 and backlight sources 12 are respectively provided on the upper and lower end faces of the lamp head 10. The lamp head 10 is fixed at one end of the lamp post 20. A socket 14 is fixedly connected to one side surface thereof through a connecting portion 13. The socket 14 can be inserted into the inside of the lamp post 20 through the end opening thereof; the connecting portion 13 and the socket 14 are integrally formed with the lamp frame 15. A wire hole 143 is provided on the socket 14. The inside of the lamp post 20 is connected to the inside of the lamp frame 15 through the wire hole 143. A control panel 40 for controlling the surface light source 11 and the backlight source 12 is provided in the middle of the lamp post 20. The wire hole 143 is used for wire connection between the control panel 40 and the surface light source 11 and the backlight source 12.

[0037] It further includes a base 30. The base 30 is a flat plate member, which is fixedly connected to the other end of the lamp post 20 through fastening screws, and uses a large flat support surface to achieve stable floor support for the lamp body.

[0038] A pair of screw columns 21 are formed inside one side of the lamp pole 20 of the present scheme, and reinforcing ribs 23 are distributed on the side surface away from the screw columns 21. At the same time, a notch 22 connected to the opening at its end is opened on the surface, and a cylindrical groove 141 that matches the clearance of the outer side of the screw column 21 is provided on the connector 14, and a connecting hole 142 that matches the inner side of the screw column 21 is provided on the upper side of the cylindrical groove 141; when the main body of the connector 14 is embedded in the lamp pole 20, the cylindrical groove 141 is wrapped around the outside of the screw column 21, which ensures the accurate alignment of the connecting hole 142 and the hole of the screw column 21. At the same time, the plug-in cooperation of the axial holes of the two makes the insertion and plugging of the connector 14 more stable.

[0039] When the main body of the socket 14 is embedded in the lamp pole 20, the connection part 13 is engaged with the notch 22, and a limiting groove 131 is provided on the connection part 13, and the edge of the notch 22 is engaged with the limiting groove 131. When the lamp holder 10 is embedded in the end of the lamp pole 20 and is initially plugged in and fixed before screws are used, the engagement and contact design between the limiting groove 131 and the edge of the notch 22 can be used to facilitate the installation of the lamp pole 20 in an inclined state, and the lamp holder 10 can be initially plugged in and fixed. The user does not need to hold the lamp holder 10 by hand, and it can also maintain a good connection at the end of the lamp pole 20 without shaking or falling off, which is convenient for the user to free up his hands for subsequent screw tightening operations.

[0040] During installation, the user can stand and tilt one side of the lamp pole 20 to install the lamp holder: 10, and insert the socket 14 and the connecting part 13 of the lamp holder: 10 into the end. The lamp holder: 10 uses the contact between the socket 14 and the inner wall of the lamp pole 20, and the bite contact at the connecting part 13, so that the main body of the lamp holder: 10 and the lamp pole 20 can be reliably initially fixed; at the same time, using the cylindrical groove 141 on the connecting seat that is clearance-matched with the screw column 21, after initial fixation, the connecting hole 142 is accurately aligned with the screw hole, and the user can easily install the fastening screw through the connecting hole 142. The installation is convenient and efficient, which greatly reduces the installation difficulty of the user.

[0041] The following is a preferred specific implementation of this product:

[0042] In order to further improve the convenience of plugging the socket 14 and the stability of the socket 14 against the inner wall of the lamp pole 20 after plugging, the side of the socket 14 is designed to be an inclined surface that is inwardly contracted from top to bottom. The inclined surface is convenient for demoulding the mold on the one hand, and convenient for guiding the plugging into the inner side of the lamp pole 20 on the other hand. At the same time, a limiting protrusion 144 is fixed on the surface of the side with the cylindrical groove 141, and the lower side of the limiting protrusion 144 is cut with an oblique angle. The role of the limiting protrusion 144 is that after the socket 14 is embedded in the lamp pole 20, it can be tightly against the inner wall of the lamp pole 20, and further because the main body of the lamp head 10 is too heavy to be suspended in the air, it causes the insertion to fall off.

[0043] In order to achieve connection limit and maintain the aesthetics at the end face, on the side of the socket 14 where the connection hole 142 is provided, an outwardly expanding planar stop 145 is formed. When the main body of the socket 14 is embedded inside the lamp post 20, the planar stop 145 fits against the end face of the lamp post 20. When the lamp head 10 is fastened by screwing to the screw post 21, the planar stop 145 plays a role of limiting and stopping.

[0044] The reinforcing rib 23 of the lamp post 20 is cut at the notch 22. To avoid interference, a corner groove 132 for avoiding the reinforcing rib 23 is communicated with the limiting groove 131. The reinforcing rib 23 at the cross-section is embedded in the corner groove 132. At the same time, the corner groove 132 also provides a certain limiting and positioning function between the socket 14 and the lamp post 20.

[0045] In order to simplify the assembly of the backlight, preferably in this embodiment, the backlight source 12 is a light strip distributed around the edge of the lamp frame 15. An annular groove 17 is formed at the edge of the lamp frame 15. The light strip is embedded in the annular groove 17, and the back plate 16 presses and prevents the inner ring part of the light strip from coming off.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
