Since each street lamp is a complete set, it not only includes the light-emitting lamp head, but also the shell and bracket for installing the lamp head. In this way, the cost of increasing the ambient brightness will be relatively high.

The modular splicing LED street light shown in FIG1-12 includes a back plate 1, which is usually made of an alloy material with good thermal conductivity and is a substrate for installing major electrical components. An outer frame 5 is fixedly connected to the edge of the back plate 1. The outer frame 5 is usually not in contact with the major heating components, so it can be made of plastic material to reduce weight and cost. The front of the back plate 1 is fixedly connected to a light-emitting board 2 located in the outer frame 5, which is composed of a plurality of LEDs connected in series and arrayed. The lower end of the outer frame 5 protrudes outward, and resilient locking pieces 8 are provided on both sides of the protrusion to achieve splicing. The main structure is that the upper end of the outer frame 5 is recessed inward, and the inner walls of the recess are provided with holes 507 on both sides for engaging with the locking member 8. The protrusions and recesses at both ends of the outer frame 5 can also fit together. The lower end of the back panel 1 also has a protruding structure aligned with the protrusion at the lower end of the outer frame 5, and the upper end of the back panel 1 also has a concave structure aligned with the recess at the upper end of the outer frame 5. In fact, the outer side surface of the outer frame 5 is aligned with the outer side surface of the back panel 1. The back panel 1 outside the light-emitting panel 2 and inside the outer frame 5 is provided with a connecting hole 101 that runs through the front and rear sides for the bolts to pass through and fix the back panel 1 in the protective shell of the lamp body.

The outer frame 5 includes an inner plug-in horizontal plate 501, which is located at the bottom in the figure. Both ends of the inner plug-in horizontal plate 501 extend upward to form plug-in plates 502. The two plug-in plates 502 are vertical and perpendicular to the horizontal inner plug-in horizontal plate 501. The upper ends of the plug-in plates 502 extend outward to form baffles 503. The two baffles 503 are parallel to the inner plug-in horizontal plate 501. The outer ends of the baffles 503 extend upward to form side plates 504. The side plates 504 are perpendicular to the baffles 503. The upper ends of the side plates 504 extend inward to form stopper plates 505. The baffle plate 503 of another outer frame 5 abuts against each other, the inner end of the limit plate 505 extends downward to form a card plate 506, which can abut against the plug plate 502 of another outer frame 5, and an embedded horizontal plate 508 is provided between the lower ends of the two card plates 506, which can abut against the inner plug horizontal plate 501 of another outer frame 5, and an inner frame 6 is fixedly connected between the inner plug horizontal plate 501 and the inner wall of the plug plate 502, and the inner frame 6 is C-shaped, one side of which is open, and the open side of the inner frame 6 faces the plug plate 502, and the plug plate 502 is used to close the inner frame 6 On the open side, the plug plate 502 is provided with a sliding hole 509 that passes through the inner and outer walls. The locking member 8 includes a locking pin 801 that cooperates with the sliding hole 509 to form a sliding pair. The locking pin 801 can extend out of the sliding hole 509, and the end of the locking pin 801 extending out of the sliding hole 509 is relatively rounded, which is convenient for sliding into the card hole 507. The end of the locking pin 801 located in the inner frame 6 is fixedly connected with a sliding plate 802, and the sliding plate 802 is perpendicular to the locking pin 801. A spring 7 is arranged between the sliding plate 802 and the inner wall of the inner frame 6. In order to ensure the stability of the spring 7, A guide column 601 is fixedly connected between the side wall of the inner frame 6 parallel to the plug plate 502 and the plug plate 502. The guide column 601 is parallel to the locking pin 801. The sliding plate 802 is provided with a guide hole 803 that passes through the left and right sides, which is used to cooperate with the guide column 601 to form a sliding pair, thereby further improving the stability of the sliding plate 802 during movement. The spring 7 is sleeved outside the guide column 601, which is used to provide the sliding plate 802 with a restoring elastic force to move closer to the plug plate 502, so that the locking pin 801 has a normal state of extending out of the sliding hole 509.

The left and right sides of the light-emitting board 2 are connected with second parallel wires 202, which are used to be electrically connected to the metal sleeve on the inner wall of the card hole 507 through the second junction boxes 4. In fact, the first parallel wire 201 and the second parallel wire 202 on the same side are connected in series. Under this structure, multiple LED street lamps are connected end to end and spliced to form a parallel structure.

Working principle: the two locking pins 801 of the first street lamp to be spliced will be electrically connected to the two poles of the power supply respectively, fix the first street lamp in the lamp housing, and then engage the bottom protrusion of the other street lamp with the top groove of the fixed street lamp. When two clicking sounds are heard, it means that the two locking pins 801 have been engaged with the locking holes 507, and the parallel wires inside the still movable street lamp are electrically connected to the parallel wires inside the fixed street lamp. Fix the second street lamp in the lamp housing again, follow this operation, splice enough street lamp units, and finally power on. Since the spliced street lamps are connected in parallel with each other, the voltages at both ends are equal, so they can all work normally. Moreover, the more spliced street lamps are, the greater the power and the greater the brightness of the entire street lamp.
