Technical Field

[0001] The utility model relates to the field of lighting devices, in particular to an economical street lamp with a compact structure. Background Art

[0002] Street lamps are one of the most common lamps in people's daily lives, especially in some prosperous cities. In order to enable people to carry out outdoor activities at night, a large number of street lamps need to be put into use outdoors to maintain the normal outdoor activities of most people at night. However, a large number of street lamps are also accompanied by a series of problems.

[0003] For example, there is the problem of street lamp manufacturing cost. Most general street lamps have a single cavity structure inside the lamp housing, and the sizes of the two ends of the cavity are basically the same. In fact, after the light source, battery and intelligent control device are installed, there is still a lot of space inside the lamp. The space inside the lamp housing cannot be reasonably utilized. Too much surplus space inside the lamp housing will make the compactness of the lamp structure defective, and also reflects the phenomenon that there are too many materials used in the manufacturing of the lamp housing, which is undoubtedly a waste of production costs. Due to the waste in production costs, the increase in the manufacturing cost of the lamp will also indirectly affect the price of the lamp, resulting in a decrease in the economic benefits of the street lamp when in use; some other street lamps will be equipped with a lens of the same size as the lamp housing to ensure the overall sealing performance of the lamp. Therefore, when there is a problem with the internal components of the lamp, the lens and the lamp need to be separated for maintenance inside the lamp, which is complicated to operate.

DETAILED DESCRIPTION

[0029] The utility model discloses an economical street lamp with compact structure. Figures 1 to 3As shown in combination, the street lamp includes a lamp housing 1, and a first cavity 2 and a second cavity 3 with different spatial volumes are respectively provided at both ends of the lamp housing 1. The lamp housing 1 outside the first cavity 2 and the lamp housing 1 outside the second cavity 3 are transitioned by an arc surface. A lamp pole joint 4 is integrally formed at one end of the lamp housing 1, and the lamp pole joint 4 is connected to the first cavity 2 through a through-wire joint 6 arranged on the wall of the lamp housing 1. A battery device 7 is provided in the first cavity 2, and a cover plate 8 is detachably connected to the opening side of the first cavity 2. A light source PCB 9 with a plurality of lamp beads inlaid on the surface is provided in the second cavity 3, and a lens 10 fixedly connected to the lamp housing 1 is provided on the outside of the light source PCB9.

[0030] It should be noted that the lamp housing 1 is provided with a first cavity 2 and a second cavity 3 of two different spatial volumes. The first cavity 2 with a larger spatial volume is used to install a battery device 7, and can also be used to install intelligent control components, such as a control base, a camera 18 base, a light controller 19, a single-ended controller, a respirator, a lightning arrester, etc., while the second cavity 3 with a smaller spatial volume can be used to install a light source PCB 9 inlaid with a number of lamp beads; the two cavities for installing lamp components provide different spaces for installing components, so a suitable cavity can be selected for installation according to the actual space requirements of the installed components, so that the internal space of the lamp housing 1 is reasonably utilized; and the method of setting two different cavities inside the lamp housing 1 can divide the space of the lamp housing 1 into areas, and a certain type of lamp components will be installed in the designated area, so that a modular structural design of the lamp can be realized. During assembly and maintenance, relevant personnel can perform corresponding operations according to the area where the components are located, which can achieve the effect of simplifying assembly and maintenance operations.

[0031] At the same time, the two spaces in the lamp housing 1 have different volumes, and the shape and structure of the lamp housing 1 are changed. The shape of the lamp housing 1 is adjusted based on the space requirements for component installation, and the structure of the lamp housing 1 is more reasonably utilized, thereby reducing the manufacturing cost of the lamp housing 1. The contour shapes at both ends of the lamp housing 1 are different and are transitioned through an arc surface, so that the wind resistance is smaller when the lamp is set at a high place. The outer contour of the lamp housing 1 can also guide rainwater falling on the top of the lamp, so that the rainwater quickly flows to the lamp and does not accumulate on the top surface of the lamp housing 1, thereby preventing rainwater accumulated on the surface of the lamp housing 1 from eroding the outer shell and flowing into the inside of the lamp housing 1 through the gap.

[0032] In addition, the integrated design of the lamp pole joint 4 and the lamp housing 1 ensures that the structure of the lamp housing 1 already has the structure for connecting to the lamp pole during production, and there is no need to perform external connection operation of the lamp pole joint 4. The lamp pole joint 4 is connected to the first cavity 2 through the wire joint 6, so that the power transmission line in the lamp pole is introduced from the lamp pole joint 4 to the inside of the lamp; the structure of the lamp housing 1 is more in line with actual production and use requirements, and the structure of the lamp housing 1 is more reasonably utilized, so that the volume of the lamp can be smaller and the internal structure of the lamp is more compact, thereby reducing the manufacturing cost of the lamp, and the production and use of the lamp are more economical.

[0033] As a further preference of the above embodiment, Figure 4 As shown, the side wall of the lamp pole joint 4 is provided with at least one first matching hole 12 for installing the positioning member 11.

[0034] Among them, when lamp poles with different radial sizes are installed into the lamp pole joint 4, the lamp poles installed in the lamp pole joint 4 can be positioned by installing positioning parts 11 such as screws and pins into the first matching hole 12. The part of the positioning part 11 extending into the first matching hole 12 compensates for the size of the lamp pole in the radial direction of the first matching hole 12, and presses on the side wall of the lamp pole, so that the position of the lamp pole is fixed between the inner wall of the first matching hole 12 and the positioning part 11, so that the lamp can be installed and fixed on lamp poles with different radial sizes, thereby improving the ability of the lamp to adapt to lamp pole installation.

[0035] As a further preference of the above embodiment, Figure 1 As shown, the cover plate 8 is made of foamed silicone, and each corner of the cover plate 8 in the circumferential direction is fixedly connected to the lamp housing 1 outside the first cavity 2 through a connecting piece 13 .

[0036] Among them, when the cover plate 8 is arranged at the open end of the first cavity 2 for sealing, the cover plate 8 material has the characteristics of ductility, high temperature resistance, tear resistance and strong fire resistance. When a smaller number of connecting parts 13 are used to fix the cover plate 8, it can also effectively play a sealing role on the first cavity 2, and can also reduce the weight of the cover plate 8, and the operation when fixing the cover plate 8 is more convenient.

[0037] As a further preference of the above embodiment, Figure 3 and Figure 5 As shown in the combination, the wall surface of the lamp housing 1 outside the first cavity 2 is provided with a first sealing groove 14 surrounding the first cavity 2, and a first sealing ring 16 with the same shape as the first sealing groove 14 is provided in the first sealing groove 14, and the cover plate 8 is located on the outside of the first sealing ring 16 and presses the first sealing ring 16 in the first sealing groove 14.

[0038] The first sealing ring 16 can enhance the sealing performance of the edge of the cover plate 8 when the cover plate 8 is fixed to the lamp housing 1, thereby preventing foreign objects from entering the first cavity 2 through the edge of the cover plate 8 and causing damage to components in the first cavity 2.

[0039] As a further preference of the above embodiment, Figure 5 As shown, the cover plate 8 is provided with a second matching hole 17, and the second matching hole 17 is matched with a camera 18 by means of threaded matching.

[0040] Among them, the setting of the camera 18 can facilitate relevant personnel to observe the environment around the lamp, so as to adjust the working state and lighting effect of the lamp according to the environment around the lamp, so that the use of the lamp can better meet the actual needs of its surrounding environment.

[0041] As a further preference of the above embodiment, Figure 2 As shown, the lamp housing 1 outside the first cavity 2 is provided with a light controller 19 .

[0042] Among them, the setting of the light controller 19 allows the lamp to adjust its own start and stop and light intensity adjustment operations according to the light intensity of its surrounding environment, so that the use of the lamp is more in line with the actual needs of its surrounding environment and the economic benefits of the lamp are higher.

[0043] As a further preference of the above embodiment, Figure 6 As shown, a plurality of heat dissipation fins 20 are provided on the inner wall of the lamp housing 1 outside the battery device 7 .

[0044] Among them, the battery device 7 will generate heat energy during the use of the lamp. Excessive heat energy has a certain impact on the performance and service life of the battery device 7. The setting of the heat dissipation fins 20 can increase the inner wall surface area of ​​the lamp housing 1 around the battery device 7, thereby quickly conducting the heat energy emitted by the battery device 7 to its surroundings, and then dissipating the heat of the battery device 7 to maintain the normal operation of the battery device 7.

[0045] As a further preference of the above embodiment, Figure 7 As shown, a heat dissipation structure 20 with a grid-shaped cross section is disposed in the second cavity 3 , and the light source PCB 9 is fixed on the outside of the heat dissipation structure 20 .

[0046] Similarly, when the lamp is working, the light emitted by the light source will also generate heat energy, and the temperature in the space around the light source PCB9 will rise, which is not conducive to the structural maintenance of the light source PCB9 and the lamp beads. The setting of the heat dissipation structure 20 can expand the inner wall surface area of ​​the lamp housing 1 around the light source PCB9, thereby quickly dissipating the heat energy around the light source PCB9, realizing the heat dissipation of the light source PCB9, and allowing the light source of the lamp to work stably.

[0047] As a further preference of the above embodiment, Figure 8 and Fig. 9 As shown in the figure, a second sealing groove 21 is arranged around the edge of the lens 10 , a second sealing ring 22 having the same shape as the second sealing groove 21 is arranged in the second sealing groove 21 , and the lens 10 presses the first sealing ring 16 against the lamp housing 1 .

[0048] Among them, since the lens 10 is connected to the lamp housing 1 with a detachable connection structure, there may be a gap between the edge of the lens 10 and the lamp housing 1, which may cause foreign objects to enter the space where the light source PCB9 is located and affect the normal operation of the light source PCB9. Therefore, a second sealing ring 22 is arranged at the edge of the lens 10 to enhance the sealing performance of the edge of the lens 10, and seal the gap between the edge of the lens 10 and the lamp housing 1, thereby ensuring that the lens 10 forms a good seal with the light source PCB9 after being installed in the lamp housing 1.

[0049] As a further preference of the above embodiment, Fig.10 As shown, the edges of the lamp housing 1 outside the second cavity 3 and the arc surface are transitioned through fillets 23, the contour cross-section of the fillet 23 is U-shaped, and the wall surface of the lamp housing 1 outside the first cavity 2 is an inclined surface 24 that gradually moves away from the center of the first cavity 2 from high to low, and the two ends of the inclined surface 24 are respectively connected to the two ends of the fillet 23.

[0050] Among them, through the setting of the rounded corners 23 and the inclined surface 24, when rainwater falls on the top surface of the lamp, the rounded corners 23 and the inclined surface 24 can guide the rainwater, so that the rainwater quickly flows out from the bottom surface of the lamp housing 1 to the outside of the lamp as a whole, further reducing the rainwater accumulated on the surface of the lamp housing 1 from eroding the outer shell and flowing into the interior of the lamp housing 1 through the gaps.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
