Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and particularly to a street lamp. Background Art

[0002] The Illuminating Engineering Society of North America (IESNA) defines road and area lighting equipment according to the photometric characteristics of lamps, the distance at which 50% of the maximum light intensity irradiates the road surface, and the maximum light intensity value, including several lighting requirements such as type1, type2, type3, and type4. Among them, type1 means that the lateral road width covered by the street lamp lighting is within 1.0 times the height of the lamp; type2 means that the lateral road width covered by the street lamp lighting is between 1.0 and 1.75 times the height of the lamp; type3 means that the lateral road width covered by the street lamp lighting is between 1.75 and 2.75 times the height of the lamp; type4 means that the lateral road width covered by the street lamp lighting is more than 2.75 times the height of the lamp. Most existing street lamps have only one light-emitting angle and can only meet one of the lighting requirements of type1, type2, type3, and type4. In order to meet more than two lighting requirements, the existing technology generally adopts a high-cost electronically controlled dimming method, or adopts the method of manually replacing the lens, or adopts multiple lenses to match the lamp board to achieve the switching of the light-emitting angle. These solutions are all high in cost and low in cost performance. Summary of the Invention

[0003] An object of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a low-cost street lamp.

[0004] The street lamp according to an embodiment of the present invention includes a lamp housing, and a carrier board, a light-transmitting panel, a lamp board, a supplementary light component, and a controller respectively disposed in the lamp housing. The supplementary light component includes a plurality of supplementary light strips. A plurality of spaced convex strips are provided on the carrier board, and the upper surface of the convex strip is inclined. The lamp board is disposed on the surface of the carrier board, and the supplementary light strips are respectively attached to the upper surface of the convex strips; a plurality of convex ribs are provided on the light-transmitting panel, and the plurality of convex ribs correspond to the plurality of convex strips one by one. A groove is provided at the bottom of the convex rib to match the corresponding convex strip. The upper surface of the convex rib is inclined and parallel to the upper surface of the convex strip. Lenses are respectively provided on the surface of the light-transmitting panel and the upper surface of the convex rib to correspond to the lamp beads on the lamp board and the supplementary light component; the controller is electrically connected to the lamp board and the lamp strip respectively to control the on / off states of the lamp board and the plurality of supplementary light strips respectively, so as to achieve multiple light outputs.

[0005] According to some embodiments of the present invention, the lenses on the light-transmitting panel and the lenses on the convex ribs have the same specifications.

[0006] According to some embodiments of the present invention, the inclination directions of the upper surfaces of the plurality of the convex strips are the same, and the inclination directions of the upper surfaces of the corresponding plurality of the convex ribs are the same.

[0007] According to some embodiments of the present invention, the range of the inclination angle δ of the upper surface of the convex strip is 0 < δ < 90°, and the range of the ratio Q of the number of the lamp beads of the supplementary light assembly to the number of the lamp beads of the lamp board is 10% to 50%.

[0008] According to some embodiments of the present invention, Q = 30%.

[0009] According to some embodiments of the present invention, on the basis of only lighting the lamp board to achieve type 2 light output, when δ = 20°, lighting both the lamp board and the supplementary light assembly can achieve type 3 light output; when δ = 30°, lighting both the lamp board and the supplementary light assembly can achieve type 4 light output.

[0010] According to some embodiments of the present invention, when δ = 25°, lighting the lamp board and lighting the supplementary light assembly with 30% brightness can achieve type 3 light output; lighting the lamp board and lighting the supplementary light assembly with 100% brightness can achieve type 4 light output.

[0011] According to some embodiments of the present invention, lighting the supplementary light assembly with 30% brightness includes only lighting 30% of the supplementary light strips, and the brightness of all the supplementary light strips is 30% respectively.

[0012] According to some embodiments of the present invention, the lamp housing includes a first groove and a second groove. The controller and the carrier board are arranged in the first groove. The light-transmitting panel is used to cover the opening of the first groove. A power supply is arranged in the second groove, and a power supply cover for covering the second groove is further arranged on the lamp housing.

[0013] According to some embodiments of the present invention, it further includes an induction component electrically connected to the controller, and a through hole is arranged on the power supply cover for installing the induction component.

[0014] The street lamp according to the embodiment of the present invention has at least the following beneficial effects: The LED lamp beads on the lamp board arranged on the surface of the carrier board form basic light output through the lenses on the light-transmitting panel. Since the upper surface of the convex strip is inclined and the upper surface of the convex rib is inclined, the supplementary light strips arranged on the convex strip are inclined to irradiate through the lenses on the convex rib, forming deflected light output at a certain angle, so that the irradiation range is wider; the controller can form a variety of light output combinations by controlling the basic light output + the deflected light output on any convex strip; when there are more supplementary light strips, the deflected light output is stronger. Combined with the basic light output, without replacing the lenses or combining multiple specifications of lenses together, various lighting requirements can be met, which is convenient for dimming and reduces the cost at the same time.

[0028] Referring to Figures 1 to 8 , a street lamp of the present invention includes a lamp housing 10, a carrier board 11, a light-transmitting panel 12, a lamp board 20, a supplementary lighting component, and a controller respectively arranged in the lamp housing 10. The supplementary lighting component includes a plurality of supplementary light bars 21. A plurality of spaced convex strips 13 are provided on the carrier board 11. The upper surface of the convex strip 13 is inclined. The lamp board 20 is arranged on the surface of the carrier board 11, and the supplementary light bars 21 are respectively attached to the upper surface of the convex strip 13 in one-to-one correspondence; a plurality of convex ribs 14 are provided on the light-transmitting panel 12. The plurality of convex ribs 14 correspond to the plurality of convex strips 13 one-to-one. A groove is provided at the bottom of the convex rib 14 to match the corresponding convex strip 13. The upper surface of the convex rib 14 is inclined and parallel to the upper surface of the convex strip 13. Lenses 15 are respectively provided on the surface of the light-transmitting panel 12 and the upper surface of the convex rib 14 to correspond to the lamp beads on the lamp board 20 and the supplementary lighting component; the controller is electrically connected to the lamp board 20 and the supplementary light bars 21 respectively to control the on / off states of the lamp board 20 and the plurality of supplementary light bars 21 respectively, so as to realize multiple light emissions. The LED lamp beads on the lamp board arranged on the surface of the carrier board form a basic light emission through the lenses on the light-transmitting panel. Since the upper surface of the convex strip is inclined and the upper surface of the convex rib is inclined, the supplementary light bars arranged on the convex strip are inclined to irradiate through the lenses on the convex rib, forming a deflected light emission at a certain angle, so that the irradiation range is wider; the controller can form multiple light emission combinations by controlling the basic light emission + the deflected light emission on any convex strip (specific light emission combinations can be seen in the specific embodiments below).

[0029] In some embodiments, the lenses 15 on the light-transmitting panel 12 and the lenses 15 on the convex ribs 14 have the same specifications. When there are more supplementary light bars, the deflected light emission is stronger. Combined with the basic light emission, without replacing the lenses or combining multiple specifications of lenses together, various lighting requirements can be met, which is convenient for dimming and reduces the cost at the same time.

[0030] Furthermore, the inclination directions of the upper surfaces of the plurality of convex strips 13 are the same, and the inclination directions of the upper surfaces of the corresponding plurality of convex ribs 14 are the same, so that the directions of the deflected light emissions are the same, increasing the deflection angle.

[0031] Such as Figure 2, the lamp housing 10 includes a first groove (not labeled in the figure) and a second groove 16. The controller and the carrier board 11 are arranged in the first groove, and the light-transmitting panel 12 is used to cover the opening of the first groove. A power supply 17 is arranged in the second groove 16, and a power supply cover 18 for covering the second groove 16 is further arranged on the lamp housing 10. It further includes an induction component 19 electrically connected to the controller, and a through hole 181 is arranged on the power supply cover 18 for installing the induction component 19.

[0032] In some embodiments, it further includes a rotating arm 32 assembly arranged on the side of the lamp housing 10. The rotating arm 32 assembly includes a joint 31 for fixing and a rotating arm 32 rotatably connected to the joint 31. The rotating arm 32 is connected to the lamp housing 10, which is convenient for mechanically adjusting the angle of the lamp body to meet more irradiation requirements.

[0033] Preferably, the inclination angle δ of the upper surface of the rib 13 ranges from 0 < δ < 90°, and the ratio Q of the number of lamp beads of the supplementary lighting component to the number of lamp beads of the lamp board ranges from 10% to 50%.

[0034] Taking Q = 30% as an example, in the first embodiment: on the basis of only lighting the lamp board 20 to achieve type 2 light output (such as Figure 5 ), when δ = 20°, both the lamp board 20 and the supplementary lighting component are lit to achieve type 3 light output (such as Figure 6 ); when δ = 30°, both the lamp board 20 and the supplementary lighting component are lit to achieve type 4 light output (such as Figure 7 ). From Figure 5 , Figure 6 and Figure 7 , it can be seen that as the deflection angle increases, since the light irradiates farther, the illuminance at the near distance decreases in turn.

[0035] In the second embodiment, δ = 25° is selected (for convenient production and processing). According to practice, when the lamp board 20 is lit and the supplementary lighting component is lit at 30% brightness, type 3 light output can be achieved; when the lamp board 20 is lit and the supplementary lighting component is lit at 100% brightness, type 4 light output can be achieved. Among them, the supplementary lighting component being lit at 30% brightness means that only 30% of the supplementary lighting strips 21 are lit, or the brightness of all the supplementary lighting strips 21 is 30% respectively. It can also be that some of the supplementary lighting strips are lit at 100% and some are dimmer, so that the overall brightness of the supplementary lighting component reaches 30%.

[0036] As Figure 8 shows, it can be seen that the horizontal distances of the three types of light output of Type2, Type3, and Type4 decrease in turn, the vertical distances increase in turn, and the light output areas increase in turn. It also further proves that the deflection angle of the supplementary lighting component gradually increases.

[0037] Those skilled in the art can easily understand that, on the premise of no conflict, the above preferred methods can be freely combined and superimposed.

[0038] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or directly or indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
