Description

Technical Field

[0001] The invention relates to the technical field of lamps, in particular to a street lamp. Background Art

[0002] The Illuminating Engineering Society of North America (IESNA) defines road and regional lighting equipment according to the photometric characteristics of the lamp, the distance at which 50% of the maximum light intensity is irradiated to the road surface, and the maximum light intensity value, including type 1, type 2, type 3, and type 4 lighting requirements. Type 1 refers to the road width covered by street lighting within 1.0 times the height of the lamp, type 2 refers to the road width covered by street lighting between 1.0 and 1.75 times the height of the lamp, type 3 refers to the road width covered by street lighting between 1.75 and 2.75 times the height of the lamp, and type 4 refers to the road width covered by street lighting more than 2.75 times the height of the lamp. Most of the existing street lamps have only one luminous angle, which can only meet one of the lighting requirements of type 1, type 2, type 3, and type 4. In order to meet more than two lighting requirements, the existing technology generally uses a high-cost electric control dimming method, or adopts a manual lens replacement method, or uses multiple lenses to match the light board to achieve the switching of the luminous angle. These solutions are all costly and cost-effective. Summary of the invention

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

[0028] Reference Figures 1 to 8 The present invention discloses a street lamp, comprising a lamp housing 10, a carrier plate 11, a light-transmitting panel 12, a light board 20, a fill light assembly and a controller, wherein the fill light assembly comprises a plurality of fill light strips 21, a plurality of convex strips 13 arranged at intervals on the carrier plate 11, the upper surface of the convex strips 13 is inclined, the light board 20 is arranged on the surface of the carrier plate 11, and the fill light strips 21 are attached to the upper surface of the convex strips 13 one by one; a plurality of convex ribs 14 are arranged on the light-transmitting panel 12, and the plurality of convex ribs 14 are attached to the upper surface of the convex strips 13. 4 corresponds to the multiple convex strips 13 one by one, the bottom of the convex rib 14 is provided with a groove 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, and the surface of the light-transmitting panel 12 and the upper surface of the convex rib 14 are respectively provided with lenses 15 to correspond to the lamp beads on the light board 20 and the fill light assembly; the controller is electrically connected to the light board 20 and the fill light strip 21 respectively to control the light board 20 and the multiple fill light strips 21 to respectively control the light on and off states of each, so as to achieve multiple light outputs. The LED lamp beads on the light board arranged on the surface of the carrier board form basic light output through the lens on the light-transmitting panel. Due to the inclination of the upper surface of the convex strip and the upper surface of the convex rib, the fill light strip arranged on the convex strip is inclined to irradiate through the lens on the convex rib, forming a certain angle of deflected light output, so that the irradiation range is wider; the controller can form multiple light output combinations by controlling the basic light output + the deflected light output on any convex strip (see the specific embodiment below for the specific light output combination).

[0029] In some embodiments, the lens 15 on the light-transmitting panel 12 has the same specifications as the lens 15 on the convex rib 14. When there are more fill light strips, the deflected light is stronger. When combined with the basic light, there is no need to replace the lens or combine lenses of multiple specifications together to meet various lighting requirements, which facilitates dimming and reduces costs.

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

[0031] like Figure 2The lamp housing 10 includes a first groove (not numbered in the figure) and a second groove 16. The controller and the carrier board 11 are arranged in the first groove. 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. The lamp housing 10 is also provided with a power supply cover 18 for covering the second groove 16. The lamp housing 10 also includes an induction component 19 electrically connected to the controller. The power supply cover 18 is provided with a through hole 181 for installing the induction component 19.

[0032] In some embodiments, a rotating arm 32 assembly is further included 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 to facilitate mechanical adjustment of the angle of the lamp body to meet more illumination requirements.

[0033] Preferably, the inclination angle δ of the upper surface of the convex strip 13 is in the range of 0<δ<90°, and the ratio Q of the number of lamp beads in the fill light assembly to the number of lamp beads in the light board is in the range of 10% to 50%.

[0034] Taking Q=30% as an example, in the first embodiment: on the basis of only lighting the light board 20 to realize type 2 light output (such as Figure 5 ), when δ = 20°, the light board 20 and the fill light component are both bright and can achieve type 3 light output (such as Figure 6 ); When δ = 30°, the light board 20 and the fill light assembly are both bright and can 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, the illumination at nearby locations decreases as the light irradiates farther away.

[0035] In the second embodiment, δ=25° is selected (for ease of production and processing). According to practice, when the light board 20 is on and the fill light component is on at 30% brightness, type 3 light emission can be achieved; when the light board 20 is on and the fill light component is on at 100% brightness, type 4 light emission can be achieved. The fill light component is on at 30% brightness, which means that only 30% of the fill light strips 21 are lit, or the brightness of all fill light strips 21 is 30%. Alternatively, some fill light strips are 100% bright, and some fill light strips are dimmed, so that the overall brightness of the fill light component reaches 30%.

[0036] like Figure 8 As shown, it can be seen that the lateral distance of the three types of light output, Type 2, Type 3, and Type 4, decreases successively, the longitudinal distance increases successively, and the light output area increases successively. This also further proves that the deflection angle of the fill light component increases gradually.

[0037] It is easy for those skilled in the art to understand that the above preferred embodiments can be freely combined and superimposed without conflict.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
