Description

Technical Field

[0001] The utility model relates to the field of street lamps, and more specifically, to a double-lamp-head LED street lamp convenient for height adjustment. Background Art

[0002] A street lamp is a lighting fixture used to provide illumination at night or in insufficient light, and is widely used in various places that require lighting, such as urban roads, parks, squares, etc., to ensure the safe passage of pedestrians and vehicles. At the same time, it can also beautify the urban night view and enhance the urban image. With the progress of technology and the improvement of environmental awareness, LED street lamps are more popular and play an increasingly important role in urban lighting.

[0003] The heights of the lamp heads of most existing LED street lamps are fixed and cannot be adjusted according to actual installation needs. This results in insufficient lighting effects in some road areas, such as curves, intersections or sidewalks, and there are lighting blind spots or dark areas, affecting the safety of pedestrians and vehicles. Traditional street lamps are inconvenient to maintain. When a street lamp fails, due to the high and fixed position of the lamp head, it is inconvenient to disassemble, and maintenance personnel need to carry professional tools for high-altitude operations, increasing the difficulty and risk of maintenance.

The first lamp post has a first sliding groove, and a plurality of first sliding seats are installed at the first lamp post. The first sliding seat has a first sliding block adapted to the first sliding groove. The first sliding seat has a first fixing bolt capable of locking the position of the first sliding seat. A plurality of first stud bolts are connected to the first sliding seat. The first LED lamp head is connected to a first substrate. The first substrate has a first stud bolt hole adapted to the first stud bolt. A first nut is installed on the first stud bolt. A plurality of first sliding seats are fixedly connected to the first substrate. The second lamp post has a second sliding groove, and a plurality of second sliding seats are installed at the second lamp post. The second sliding seat has a second sliding block adapted to the second sliding groove. The second sliding seat has a second fixing bolt capable of locking the position of the second sliding seat. A plurality of second stud bolts are connected to the second sliding seat. The second LED lamp head is connected to a second substrate. The second substrate has a second stud bolt hole adapted to the second stud bolt. A second nut is installed on the second stud bolt. A plurality of second sliding seats are fixedly connected to the second substrate.

[0006] Furthermore, two reinforcing connecting plates are connected between the first and second lamp posts. There is a vertical through groove with an open top at the reinforcing connecting plate. A first sliding plate and a second sliding plate are installed at the two reinforcing connecting plates. The first and second sliding plates both pass through the two vertical through grooves. Two first side limiting plates are connected to the first sliding plate, and two second side limiting plates are connected to the second sliding plate. The first sliding plate has a plurality of first threaded holes, and at least one first threaded hole is installed with a first tightening bolt that tightens against the first sliding seat. The second sliding plate has a plurality of second threaded holes, and at least one second threaded hole is installed with a second tightening bolt that tightens against the second sliding seat.

[0007] Thus, the installation stability of the first sliding seat and the second sliding seat is enhanced, and the lamp head is stably installed.

[0008] Furthermore, a top connecting plate is connected to the top end of the second lamp post. The top connecting plate can close the open top of the vertical through groove. The top end of the first lamp post has a plurality of third studs, and the top connecting plate has third stud holes that cooperate with the third studs. A third nut is installed at the third stud.

[0009] Thus, the open top of the vertical through groove is closed.

[0010] Furthermore, the bottom of the top connecting plate has a plurality of positioning posts, and the top end of the reinforcing connecting plate has positioning holes that cooperate with the positioning posts.

[0011] Thus, the top connecting plate is accurately positioned during installation.

[0012] Furthermore, there are four first sliding seats and two second sliding seats, and the height of the first lamp post is greater than the height of the second lamp post.

[0013] Thus, the first LED lamp head and the second LED lamp head are more firmly installed.

[0014] Furthermore, the reinforcing connecting plate extends along the length direction of the first lamp post.

[0015] Furthermore, there are a plurality of first reinforcing ribs between the first substrate and the first LED lamp head, and a plurality of second reinforcing ribs between the second substrate and the second LED lamp head.

[0016] Thus, the first LED lamp head is firmly connected to the first substrate, and the second LED lamp head is firmly connected to the second substrate.
