Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, specifically to an outdoor camping light. Background Technology

[0002] Outdoor camping lights are used to provide a light source outdoors and generally need to have two lighting capabilities. The first is focused lighting, which generally functions like a flashlight, concentrating the light on a small area. The second is area lighting, which typically involves passing the light from the LED through a lens to create a localized lighting effect.

[0003] The existing outdoor camping lights have unreasonable optical path structure designs for spotlighting and area lighting. Spotlighting suffers from halo and scattering problems, while area lighting using fogging lamp lenses has insufficient light intensity. These issues urgently need to be improved. Utility Model Content

[0004] To address the problems existing in the prior art, this application aims to provide an outdoor camping light. This application offers better focused lighting effects, and its area lighting has the advantages of being uniform, soft, and having sufficient light intensity.

[0005] An outdoor camping light as described in this application includes:

[0006] A lamp head assembly includes a first housing, a first light-emitting element, a second light-emitting element, a focusing element, and a light-transmitting sheet. The light-transmitting sheet is embedded in the end of the first housing. The first light-emitting element and the focusing element are both disposed within the first housing and correspond to the light-transmitting sheet. The focusing element has a partially elliptical structure and has a first end face and a second end face parallel to the plane of the light-transmitting sheet. The first end face passes through the focal point of the ellipse and is parallel to the minor axis of the ellipse. The second end face passes through the minor axis of the ellipse. The middle portion of the first end face is recessed towards the second end face to form a partially spherical first groove, and the inner surface of the first groove is a first spherical surface. The middle portion of the second end face is recessed towards the first end face to form a second groove. The side of the second groove near the first end face protrudes away from the first end face to form a second spherical surface, and the radius of the first spherical surface is smaller than the radius of the second spherical surface. The first light-emitting element is disposed within the first groove.

[0007] A lamp barrel assembly, one end of which is connected to the lamp head assembly, and the second light-emitting element is disposed on the side close to the lamp barrel assembly;

[0008] A tail assembly is connected to the end of the lamp tube assembly that is away from the lamp head assembly.

[0009] Preferably, the lamp assembly includes an outer lamp, a light guide tube, and several sets of refractive lens groups, wherein both the outer lamp and the light guide tube are made of light-transmitting material;

[0010] The light guide tube is sleeved inside the outer lamp tube, forming an outward light path between the outer lamp tube and the light guide tube. The second light-emitting element includes an inner ring lamp bead and an outer ring lamp bead. The inner ring lamp bead is arranged corresponding to the light guide tube, and the outer ring lamp bead is arranged corresponding to the outward light path. Several sets of refractive lens groups are arranged corresponding to the inner ring lamp bead. Each refractive lens group includes a first refractive surface and a second refractive surface. The first refractive surface is inclined to the plane where the inner ring lamp bead is located, and the horizontal projection surface of the first refractive surface at least partially coincides with the inner ring lamp bead. The second refractive surface is parallel to the first refractive surface and is arranged on the side of the inner ring lamp bead away from the first refractive surface. The refractive lens group is used to refract the emitted light from the inner ring lamp bead into the interior of the light guide tube.

[0011] Preferably, the light guide tube has a focusing structure at a position corresponding to the outer ring lamp beads, and the focusing structure is a spherical part that protrudes away from the outer ring lamp beads.

[0012] Preferably, both the inner and outer surfaces of the light guide tube are formed with a diffuse reflection structure, the diffuse reflection structure including multiple sets of convex and concave ridges arranged alternately along the circumference of the light guide tube.

[0013] Preferably, the lamp head assembly further includes a lamp main board, an indicator light, control buttons, and a control board. The lamp main board is electrically connected to the first light-emitting element and the second light-emitting element, respectively, and the control board is electrically connected to the lamp main board, the indicator light, and the control buttons, respectively.

[0014] Preferably, the control button is located on the outer side of the first housing, and a waterproof sheet is provided on the control button;

[0015] A first sealing ring is provided at the connection between the light-transmitting sheet and the first housing.

[0018] Preferably, a waterproof cotton is provided between the bracket nut and the second housing.

[0019] Preferably, a lifting ring is provided on the end face of the second housing away from the lamp assembly.

[0020] The outdoor camping light described in this application has the advantage that by setting a light-concentrating element that is partially elliptical, the first light-emitting element is placed at the focal point of the light-concentrating element, and the light is concentrated by the first spherical surface and the second spherical surface, so that the light-concentrating element can effectively concentrate the light emitted by the first light-emitting element and achieve a more concentrated lighting effect.

[0021] Furthermore, by setting a light guide tube with concave and convex surfaces, and in conjunction with components such as an external lamp tube and a refractive lens group, the emitted light from the second light-emitting element can be diffused through the light guide tube and emitted from the external lamp tube, which can soften the outward beam and achieve a uniform and soft area lighting effect, with minimal loss of light intensity and sufficient lighting intensity.

[0038] like Figures 1-4 As shown, an outdoor camping light according to this application includes:

[0039] The lamp holder assembly 10 includes a first housing 101, a first light-emitting element 102a, a second light-emitting element 102b, a focusing element 103, and a light-transmitting sheet 104. The first housing 101 has a hollow cylindrical structure, such as a cylinder, a square prism, or a hexagonal prism. The light-transmitting sheet 104 is embedded at the end of the first housing 101, for example, at the axial position. The first light-emitting element 102a and the focusing element 103 are both disposed within the first housing 101 and correspond to the light-transmitting sheet 104. Specifically, the first light-emitting element 102a and the focusing element 103 are both located at the axial position of the first housing 101.

[0040] Please refer to the detailed information. Figure 4 The light-concentrating element 103 has a partially elliptical structure, similar to a cup. The light-concentrating element 103 has a first end face and a second end face parallel to the plane of the light-transmitting sheet 104. Figure 3 Taking the direction shown as an example, it has an upper end face and a lower end face, with the lower end face located on one side close to the light-transmitting sheet 104 and the upper end face located on the other side.

[0041] The projection of the focusing element 103 in the frontal view direction yields an incomplete ellipse. Please refer to the detailed description. Figure 4 To facilitate the description of the relative positions of the focusing element 103 and the first light-emitting element 102a, the ellipse in which the focusing element 103 is projected is filled with dashed lines. It can be seen that the outer contour of the focusing element 103 overlaps with the ellipse. The first end face passes through the focal point of the ellipse in which the focusing element 103 is located and is parallel to the minor axis of the ellipse. The second end face passes through the minor axis of the ellipse in which the focusing element 103 is located.

[0042] The middle portion of the first end face is recessed towards the second end face to form a partially spherical, for example, hemispherical, first groove, meaning the first groove is located at the focal point of the ellipse containing the light-concentrating element 103. The middle portion of the second end face is also recessed towards the first end face to form a second groove, such as... Figure 3 As shown, the groove is a rectangular channel. The side of the second groove closest to the first end face, i.e., with... Figure 3 Taking the direction shown as an example, the top surface protrudes downwards in a direction away from the first end face, forming a second spherical surface, and the radius of the first spherical surface is smaller than the radius of the second spherical surface. Figure 4 In this case, R1 is less than R2. The first light-emitting element 102a is disposed in the first groove, and the light emission direction is towards the direction of the light-transmitting sheet 104. That is, the first light-emitting element 102a is disposed at the focal point of the ellipse where the light-concentrating element 103 is located. The principle is as follows: Figure 4 As shown ( Figure 4 (The middle arrow indicates the direction of the light) The light source is set at the focal point of the ellipse. The light emitted from the outside of the light source is reflected by the inner wall of the focusing member 103 located on the ellipse and can be emitted along the major axis of the ellipse. In addition, the light emitted from the inside of the light source can also be emitted along the major axis after passing through the two spherical surfaces. This can effectively concentrate the light emitted from the first light-emitting element 102a after passing through the focusing member 103 to form a concentrated beam of light and improve the focused lighting effect.

[0043] Details as follows Figures 5-8 As shown, the lamp assembly 20 includes an outer lamp tube 201, a light guide tube 202, and several refractive lens groups 203. Both the outer lamp tube 201 and the light guide tube 202 are made of light-transmitting materials, such as light-transmitting PC. Please refer to the detailed description. Figure 6 The light guide tube 202 is coaxially arranged with the outer lamp tube 201, and the light guide tube 202 is sleeved inside the outer lamp tube 201. The gap between the outer lamp tube 201 and the light guide tube 202 is the outward light path L. The second light-emitting element 102b is disposed at one end near the outer lamp tube 201. The second light-emitting element 102b includes multiple LEDs, which are circumferentially distributed along the axis of the outer lamp tube 201, including inner ring LEDs and outer ring LEDs. The inner ring LEDs are arranged corresponding to the light guide tube 202, that is, within the horizontal projection of the light guide tube 202, and the outer ring LEDs are arranged corresponding to the outward light path.

[0044] Several sets of refractive lens groups 203 are arranged corresponding to the inner ring lamp beads. Specifically, the refractive lens group 203 includes a first refractive surface and a second refractive surface. The first refractive surface is inclined to the plane where the inner ring lamp beads are located, with a specific inclination angle of 45°. The horizontal projection surface of the first refractive surface, that is, the projection surface on the plane where the inner ring lamp beads are located, at least partially coincides with the inner ring lamp beads, so as to reflect the emitted light from the inner ring lamp beads. The second refractive surface is arranged on the side of the inner ring lamp beads away from the first refractive surface. The second refractive surface is used to reflect the light reflected by the first refractive surface again, so that the light enters the cylinder wall of the light guide tube 202.

[0045] Furthermore, such as Figure 7 As shown, the light guide tube 202 has a focusing structure 2021 at a position corresponding to the outer ring lamp beads. The focusing structure 2021 is a spherical part protruding away from the outer ring lamp beads, specifically a hemisphere. The spherical surface focuses the light on the structure of the outer ring lamp beads, so that the emission direction of the outer ring lamp beads is as close as possible to the axial direction of the light guide tube 202.

[0046] like Figure 7 , Figure 8 As shown, both the inner and outer surfaces of the light guide tube 202 have diffuse reflection structures 2022. The diffuse reflection structure 2022 includes multiple sets of alternating convex and concave surfaces arranged along the circumference of the guide tube. Specifically, the convex surfaces on the outer surface of the light guide tube 202 refer to the edge structures formed by protruding outwards along the circumference, while the concave surfaces refer to the edge grooves formed by indentation in the circumference. This creates an alternating distribution of convex and concave surfaces. The diffuse reflection structure 2022 on the inner surface can be understood by referring to the structure on the outer surface, and will not be elaborated further here. The aforementioned diffuse reflection structure 2022 allows light entering the light guide tube 202 to be reflected at a certain angle in the circumference. Combined with the reflection from the outer light tube, this forms a diffuse reflection effect with multiple sets of convex and concave surfaces, achieving the purpose of soft and uniform emitted light.

[0047] Furthermore, in this embodiment, the lamp head assembly 10 also includes a lamp main board 105, indicator lights 106, control buttons 107, and a control board 108. The lamp main board 105 is electrically connected to the first light-emitting element 102a and the second light-emitting element 102b, respectively, and is used to control the light-emitting action of the light-emitting elements. The control board 108 can be a commonly used control main board, such as an MCU. The control board 108 is electrically connected to the lamp main board 105, indicator lights 106, and control buttons 107, respectively, and is used to control the operation of actuators such as light-emitting elements and indicator lights 106 according to the instructions input by the control buttons 107. A baffle 111 is provided between adjacent indicator lights 106 to separate adjacent indicator lights 106.

[0048] Battery 6 is located inside the lamp tube and is used to provide electrical power.

[0049] Furthermore, in this embodiment, the control button 107 is disposed on the outer side of the first housing 101, and the control button 107 is covered with a waterproof sheet 109. In other optional embodiments, a waterproof ring 112 is provided at the opening of the first housing 101 to prevent rainwater from entering the first housing 101.

[0050] A first sealing ring 110, specifically an O-ring, is provided at the connection between the light-transmitting sheet 104 and the first housing 101 to prevent water from entering the light-transmitting sheet 104.

[0051] Furthermore, in this embodiment, a second sealing ring 4 is provided at the connection between the lamp tube assembly 20 and the lamp head assembly 10, and a third sealing ring 5 is provided at the connection between the lamp tube assembly 20 and the lamp tail assembly 30. Both are O-ring rubber rings, which can prevent water from entering at the connection.

[0052] Furthermore, in this embodiment, as Figure 9 As shown, the lamp tail assembly 30 includes a second housing 301 and a bracket nut 302 for connecting to an external bracket. The bracket nut 302 is embedded in the end face of the second housing 301 away from the lamp tube assembly 20. The bracket nut 302 can be bolted to the external bracket, allowing the outdoor camping lamp to stand upright on the bracket for easy installation. Furthermore, a waterproof cotton 303, such as EVA cotton, is provided between the bracket nut 302 and the second housing 301 to prevent water from entering the second housing 301 through the bracket nut 302.

[0053] Furthermore, in this embodiment, a lifting ring 304 is provided on the end face of the second housing 301 away from the lamp tube assembly 20. One end of the lifting ring 304 is hinged to the second housing 301, which facilitates the hoisting of the outdoor camping light.

[0054] This application has better focused lighting effect, and the area lighting has the advantages of being uniform, soft, and having sufficient light intensity.
