Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically to a dual-source searchlight for night navigation lighting. Background Technology

[0002] Existing searchlights used in special occasions mostly emit light directly after the light source is diffused through a lens, resulting in high light loss and low utilization of the generated light. Some lamps also add a reflector cup around the light source for focusing. The cup has a tapered cylindrical structure and is placed around the light source to reflect the lateral diffused light, causing it to be emitted through the lens. However, the light utilization rate of this method can only reach 50%-60%, resulting in high light loss and poor overall lighting effect. In addition, existing searchlights are difficult to flexibly adjust the illumination angle and quickly switch between dual light sources.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a searchlight for illumination [CN202323255328.1], which includes a lampshade with a light-transmitting plate. Inside the lampshade, there is a first light source group and several second light source groups surrounding the first light source group. The first light source group includes an electric light source one, a reflector cup one for receiving and reflecting the light emitted by the electric light source one, and a plano-concave lens for reflecting the light emitted by the reflector cup one. The second light source group includes an electric light source two, which has a double reflector cup. The double reflector cup includes a reflector cup two that partially covers the electric light source two. The reflector cup two has a reflective surface two facing the electric light source two. The reflective surface two reflects the light emitted by the electric light source two to its side and rear and converges into several virtual light-emitting points. The second light source group also includes a reflector cup three for receiving the virtual light-emitting points. The reflector cup three has a reflective surface three that directly reflects the virtual light-emitting points out of the light-transmitting plate.

[0004] The above solution has solved the problems of high light efficiency loss and poor lighting effect of existing searchlights to a certain extent. However, the solution still has many shortcomings, such as difficulty in flexibly adjusting the searchlight angle and quickly switching between dual light sources. Summary of the Invention

[0018] In the aforementioned dual-light source searchlight for night navigation illumination, the positioning lamp holder is provided with a strip-shaped lifting groove, and the rotating adjustment rod is set in the strip-shaped lifting groove.

[0019] In the aforementioned dual-source searchlight for night navigation illumination, a switching adjustment switch is located on the outer circumference of the threaded connector, and the switching adjustment switch is connected to a switch connection wire passing through the threaded connector.

[0020] In the aforementioned dual-source searchlight for night navigation lighting, one end of the switch connection line is connected to an external power supply, and the other end is respectively provided with a first power supply branch line connected to the first lamp tube and a second power supply branch line connected to the second lamp tube.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-6 As shown, a dual-source searchlight for night navigation includes a positioning lamp holder 1. The upper end of the positioning lamp holder 1 is connected to an annular lamp tube structure 3 via a rotating adjustment component 2. The annular lamp tube structure 3 has two semi-circular light source reflectors 4 arranged on its inner circumference. An adjustment seat structure 5 is provided between the bottom of the positioning lamp holder 1 and the positioning lamp holder 1. A conversion adjustment switch 6 is provided on the upper end of the adjustment seat structure 5 and is connected to the annular lamp tube structure 3.

[0031] The ring-shaped lamp tube structure 3 includes a lamp tube body 31, in which a first lamp tube 32 and a second lamp tube 33 are respectively arranged. The outer wall of the lamp tube body 31 is provided with a first on / off switch 34 connected to the first lamp tube 32 and a second on / off switch 35 connected to the second lamp tube 33. The first on / off switch 34 and the second on / off switch 35 are connected to the internal power supply 37.

[0032] The light sources of the first lamp tube 32 and the second lamp tube 33 are focused by the reflector 4 and emitted to achieve the function of night navigation lighting.

[0033] As can be seen, a vent valve 36 is provided at the lower end of the lamp body 31.

[0034] The vent valve 36 maintains the air pressure balance inside and outside the lamp body 31 through gas flow, preventing damage to components due to temperature changes.

[0035] Furthermore, each of the light source reflectors 4 has an L-shaped limiting part 41 on one side that is close to the other, and the limiting part 41 has a linkage connection hole 42.

[0036] Furthermore, the rotation adjustment assembly 2 includes a rotation adjustment rod 21 disposed on the positioning lamp holder 1. One end of the rotation adjustment rod 21 is disposed on the outer wall of the positioning lamp holder 1 and the other end passes through the inner wall of the lamp tube body 31 and is respectively connected to the corresponding light source reflector 4.

[0037] The reflection angles of the two light source reflectors 4 can be adjusted separately by rotating the adjustment rod 21 to meet the needs of multi-angle illumination.

[0038] Specifically, a positioning plate frame 22 is connected to the inner wall of one end of the positioning lamp holder 1. The outer wall of the positioning plate frame 22 is provided with an arc-shaped rotation stroke limiting groove 23. A limiting rod 24 is provided on the positioning lamp holder 1. One end of the limiting rod 24 has a rotating knob 25 and the other end is located in the rotation stroke limiting groove 23.

[0039] The rotation stroke limiting groove 23 is provided with several threaded positioning holes, which are used to adjust the rotation angle and then tighten the limiting rod 24 to fix it.

[0040] The rotational travel limit groove 236 is used to limit the rotational adjustment range of the positioning lamp holder 1.

[0041] More specifically, the adjustment seat structure 5 includes an adjustment knob 51 located at the bottom of the positioning lamp holder 1, a threaded adjustment hole 52 at the upper end of the adjustment knob 51, a threaded connector 53 at the bottom of the lamp body 31, and a threaded lifting rod 54 at the lower end of the threaded connector 53 corresponding to the threaded adjustment hole 52.

[0042] By rotating the adjustment knob 51, the internal threaded adjustment hole 52 of the adjustment knob 51 is linked with the threaded lifting rod 54 to achieve the height adjustment of the lamp body 31.

[0043] In detail, the positioning lamp holder 1 is provided with a strip-shaped lifting groove 55, and the rotating adjustment rod 21 is set in the strip-shaped lifting groove 55.

[0044] Preferably, the changeover adjustment switch 6 is located on the outer side of the threaded terminal 53, and the changeover adjustment switch 6 is connected to the switch connection line 61 that passes through the threaded terminal 53.

[0046] The internal power supply 37 is connected in series with the first on / off switch 34 and the second on / off switch 35 to provide independent on / off control function.

[0047] The switching switch 6 is used to switch the power supply between the first lamp tube 32 and the second lamp tube 33.

[0048] In summary, the principle of this embodiment is as follows: by rotating the adjustment knob 51, the height of the lamp body 31 can be adjusted in conjunction with the threaded lifting rod 54. Secondly, the light source can be switched using the conversion adjustment switch 6. During the switching process, due to the internal power supply 37 and the first on / off switch 34 and the second on / off switch 35, the light source can be switched without interrupting the power supply. Furthermore, the angles of the two light source reflectors 4 can be independently adjusted by rotating the adjustment rod 21, and the overall illumination angle of the positioning lamp holder 1 can be adjusted by the limiting rod 24, resulting in good performance.
