[0002] A floodlight is a light source that can illuminate evenly in all directions. It produces highly diffuse, non-directional light, and produces soft and transparent shadows. When used to illuminate objects, the speed at which the illumination fades is much slower than when using a spotlight. Floodlights are widely used in billboards, roads, railway tunnels, bridges, culverts, squares, buildings and other scenes.

[0003] The beam angle of a floodlight directly affects its lighting range, and further affects the lighting effect. The beam angles of existing floodlights are mostly fixed, and the beam angle cannot be adjusted, which limits the use scenarios of the floodlights. Utility Model Content

[0034] In the claims, specification and the above drawings of the utility model, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.

[0035] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0036] In the claims, specification and the above-mentioned drawings of the utility model, if the term "bonding connection" is used, its implementation methods include but are not limited to bonding after bonding, welding after bonding, connecting through threaded connectors after bonding, etc.

[0037] Please also read Figures 1 to 7 Now, the floodlight provided by the utility model is described. The floodlight comprises a housing 1, a lighting assembly 2, an elastic stop assembly 3 and an adjustment assembly 4; the lighting assembly 2 comprises a lens 210 disposed in the housing 1 and movable along the front-back direction, and also comprises a light source 220 disposed at the rear side of the lens 210 and fixed to the housing 1; the elastic stop assembly 3 is disposed between the housing 1 and the lens 210, and is configured with a preload force for making the lens 210 move backwards and close to the light source 220; the adjustment assembly 4 comprises a rotating shaft 410 and a cam 420, the rotating shaft 410 is disposed perpendicular to the front-back direction and is rotatably connected to the housing 1; the cam 420 is coaxially fixed to the rotating shaft 410, and the outer profile of the cam 420 can abut against the rear side of the lens 210.

[0038] In this embodiment, a connecting bracket 5 is provided on the outer side of the housing 1, and the connecting bracket 5 can realize the connection between the floodlight and the installation base 211 (such as a wall or a column).

[0039] In this embodiment, the light source 220 includes a light source board and a plurality of point light sources arranged on the front side of the light source board, and the implementation of the point light source includes but is not limited to LED point light sources. It should be noted that the rotating shaft 410 and the cam 420 need to be staggered with the light source 220 to avoid affecting the light output of the light source 220; specifically, the cam 420 is staggered with the light source 220 in the axial direction of the rotating shaft 410, and the rotating shaft 410 can be arranged at the rear side of the light source 220, or the rotating shaft 410 is shorter and is also staggered with the light source 220 in its own axial direction.

[0040] The radius of the cam 420 corresponding to the contact point between the outer contour surface of the cam 420 and the lens 210 is defined as the adjustment radius. In this embodiment, the smaller the distance between the lens 210 and the light source 220 (i.e., the smaller the adjustment radius), the larger the beam angle; the larger the distance between the lens 210 and the light source 220 (i.e., the larger the adjustment radius), the smaller the beam angle. Figure 4 Taking perspective as an example, Figure 4 The beam angle in the middle value is at an intermediate value. By rotating the rotating shaft 410 clockwise, the cam 420 is driven to rotate clockwise, the adjustment radius is gradually reduced, and the lens 210 is gradually moved backward to increase the beam angle; by rotating the rotating shaft 410 counterclockwise, the cam 420 is driven to rotate counterclockwise, the adjustment radius is gradually increased, and the lens 210 is gradually moved forward to reduce the beam angle.

[0041] In this embodiment, the lens 210 has a base 211 and a lens 210 body. The lens 210 body corresponds to the aforementioned point light source one by one. The lens 210 body is arranged on the base 211, and the rear side surface of the base 211 abuts against the cam 420. The elastic stopper provides a backward elastic force to ensure that the lens 210 can abut against the outer profile surface of the cam 420 during the forward and backward movement of the lens 210, so that the lens 210 maintains position stability in a direction perpendicular to the forward and backward direction, avoids the lens 210 body and the point light source from being misaligned, and thus ensures the lighting effect.

[0042] Compared with the prior art, the floodlight provided by this embodiment is that the light emitted from the front side of the light source 220 is emitted forward after being dimmed by the lens 210, and the distance between the lens 210 and the light source 220 directly affects the beam angle; if the beam angle is to be changed, the rotating shaft 410 is rotated to drive the cam 420 to rotate, and the contact point between the outer profile of the cam 420 and the lens 210 changes (i.e., the adjustment radius changes). Under the limiting action of the elastic limiting component 3, the lens 210 can move in the front-to-back direction, thereby changing the distance between the lens 210 and the light source 220, and finally completing the adjustment of the beam angle. The floodlight of this embodiment can adjust the beam angle, and the adjustment structure is simple, and the adjustment operation is also very convenient, which is conducive to expanding the use scenarios of the floodlight and realizing multi-angle and multi-scenario applications.

[0043] See also Figures 4 to 7 In some specific embodiments of the cam 420, a plurality of limiting protrusions 421 distributed along the circumference of the cam 420 are provided on the outer contour surface of the cam 420, and a limiting groove 213 is provided on the rear side surface of the lens 210. The limiting groove 213 selectively engages with one of the limiting protrusions 421 to limit the displacement of the cam 420 in the circumferential direction of the cam 420, and fixes the designated contact point on the cam 420 at the position of the limiting groove 213, so as to avoid the problem that the cam 420 rotates after being adjusted into place, resulting in a change in the beam angle, thereby improving the reliability of applicability. It should be noted that the number of limiting protrusions 421 provided represents the optional adjustment value of the beam angle. The present application exemplarily shows an implementation method in which three limiting protrusions 421 are provided on a cam 420. Figure 4 Taking the viewing angle as an example, the three limiting protrusions 421 correspond to beam angles of 90°, 75° and 50° from left to right respectively; of course, the setting quantity and adjustable angle of the limiting protrusion 421 can be selected according to adjustment needs, and no sole limitation is made here.

[0044] More specifically, in order to facilitate the removal from the limiting groove 213 during adjustment, the edges of the limiting protrusion 421 are all rounded; at the same time, in order to improve the structural strength of the limiting protrusion 421 and avoid its breakage, the limiting boss and the main body of the cam 420 are integrally formed, and the contour of the limiting protrusion 421 on the cross-section perpendicular to the circumference of the rotating shaft 410 is trapezoidal, and the large end of the trapezoid is connected to the main body of the cam 420.

[0045] In some embodiments, two groups of cams 420 are provided, and the two groups of cams 420 are symmetrically disposed on opposite sides of the lens 210. Figures 5 to 7 As shown. Each group has at least one cam 420, and this embodiment exemplarily shows a setting mode in which one group has one cam 420. In this embodiment, the two groups of cams 420 are respectively in contact with the two sides of the lens 210 to balance the force on the lens 210 and prevent the lens 210 from being skewed. At the same time, the two groups of cams 420 also avoid the light source 220 to avoid affecting the light emission of the light source 220.

[0046] In this embodiment, two groups of cams 420 can be arranged on the same rotating shaft 410, and the two groups of cams 420 can be driven to rotate simultaneously by the rotation of the same rotating shaft 410. Alternatively, the groups of cams 420 correspond to the rotating shafts 410 one by one (i.e., one group of cams 420 is arranged on one rotating shaft 410), and the two rotating shafts 410 need to be adjusted at the same time to drive the groups of cams 420 on both sides to rotate; in this embodiment, the rotating shafts 410 on both sides need to be coaxially arranged.

[0047] See also Figures 1 to 7In some embodiments, at least one end of the rotating shaft 410 is fixedly provided with an adjusting button 430, and the adjusting button 430 is exposed outside the housing 1 so as to be adjusted from the outside of the housing 1. In this embodiment, one end of the rotating shaft 410 is arranged opposite to the connecting bracket 5, and the other end is provided with the adjusting button 430, so that the adjustment operation space is larger and the adjustment operation is convenient.

[0048] In some embodiments, an adjustment hole 101 is formed on the side wall of the shell 1 (specifically, the side wall of the main shell 110), and the adjustment button 430 is passed through the adjustment hole 101. The adjustment hole 101 and the adjustment hole 101 are both coaxially arranged with the rotating shaft 410; a damping ring 6 is provided between the adjusting button 430 and the adjusting hole 101, and the damping ring 6 is respectively abutted against the inner walls of the adjusting button 430 and the adjusting hole 101. By cooperating with the adjustment hole 101 and the damping ring 6, the displacement of the adjusting button 430 can be effectively limited in the radial direction of the rotating shaft 410, thereby ensuring the stability of its position and the sealing of the assembly of the adjusting button 430 and the outer shell 1; at the same time, the damping ring 6 plays a role of damping limit between the outer shell 1 and the adjusting button 430. When the adjusting button 430 drives the rotating shaft 410 to rotate a certain angle, if the screwing force is removed, the adjusting button 430 and the rotating shaft 410 can be fixed in this position and will not rotate easily, which is conducive to maintaining the position stability of the rotating shaft 410 and the cam 420, and ultimately ensuring the reliability of the beam angle adjustment.

[0049] In specific implementation, in order to enhance the damping effect, a plurality of mounting ring grooves are coaxially arranged on the outer peripheral surface of the adjusting button 430 , and a plurality of damping rings 6 are provided, which are snap-fitted into the corresponding mounting ring grooves one by one to increase the damping contact area with the inner wall of the adjusting hole 101 .

[0050] On the basis of setting the adjustment button 430, participating Figure 2 and Figure 3 The housing 1 also includes an axial limit member 130, and a limit ring groove 431 is formed on the outer peripheral surface of the adjusting button 430. The axial limit member 130 is fixed to the housing 1 and extends into the limit ring groove 431 to limit the displacement of the adjusting button 430 in the axial direction of the rotating shaft 410, thereby preventing the adjusting button 430 from falling off the housing 1 and maintaining the stability of the position in the opening direction of the adjusting hole 101.

[0051] Specifically, the axial limit member 130 is a bent plate-shaped component, one side of which is fixedly connected to the shell 1 by a fastener, and the edge of the other side is formed with an arcuate edge 131 that is adapted to the limit ring groove 431. The arcuate edge 131 enables the axial limit member 130 to have a clamping adaptation area with the limit ring groove 431.

[0052] In some specific embodiments of the adjusting button 430, an adjusting groove 432 is formed on the outer side of the adjusting button 430, and a tool can be inserted into the adjusting groove 432, and the adjusting button 430 can be screwed by the tool. This design method can prevent the axial end surface of the adjusting button 430 from protruding from the side wall surface of the housing 1, and prevent the adjusting button 430 from being rotated by friction and collision in the non-adjustment state, thereby ensuring the reliability of use. In specific implementation, the shape of the adjusting groove 432 includes but is not limited to a "I"-shaped groove, a "X"-shaped groove, etc., which can meet the function of insertion and torque transmission.

[0053] Of course, the adjustment button can also be extended out of the housing 1 so that the operator can directly grasp the outer surface of the adjustment button 430 for adjustment. The specific implementation method will not be repeated here.

[0054] See also Figure 1 and Figure 3 In some embodiments, an angle adjustment mark 102 (including multiple angle values) corresponding to the adjustment button 430 is provided on the housing 1, and a corresponding pointing mark is formed on the adjustment button 430. When the pointing mark corresponds to one of the angle adjustment marks 102, it means that the beam angle is adjusted to the value corresponding to the angle adjustment mark 102, and the current state of the cam 420 can be intuitively displayed, which is convenient for the operator to judge whether the adjustment is in place. The angle adjustment mark 102 can be in the form of numbers, graphics, etc., and is not limited here. In addition, the pointing mark can be an icon formed separately on the adjustment button 430, or it can be a directional mark composed of a special shape of the adjustment slot 432 (for example, one end of the "I"-shaped slot in the figure can be used as a direction for the angle adjustment mark 102).

[0055] In some embodiments, the housing 1 may be Figures 1 to 4 In the structure shown, the housing 1 includes a main housing 110 and a light-transmitting cover 120. The light-transmitting cover 120 is covered at the front opening of the main housing 110 to ensure the sealing of the housing inner cavity and to transmit the light emitted through the lens 210 forward. Based on this, in order to achieve size optimization in the direction perpendicular to the front-back direction and simplify the structure of the elastic limit assembly 3, the elastic limit assembly 3 includes a plurality of elastic members 310. The elastic members 310 are arranged between the light-transmitting cover and the lens 210. The plurality of elastic members 310 are symmetrically distributed on opposite sides of the lens 210 to ensure that the lens 210 is evenly stressed and avoid the lens 210 from being skewed. In this embodiment, two groups of elastic members 310 are provided and are distributed on both sides of the front of the lens 210 along the axial direction of the rotating shaft 410.

[0056] In this embodiment, the light-transmitting cover 120 may be a flat plate-shaped member (eg Figures 1 to 4 As shown), it can also be a spherical plate, a corrugated plate-shaped component, etc., which is not limited here.

[0057] See also Figures 2 to 5 In some specific embodiments of the elastic member 310, the elastic member 310 includes an integrally arranged connecting piece 311 and two spring pieces 312. The connecting piece 311 is fitted and connected to the front side of the lens 210. The rear ends of the two spring pieces 312 are respectively connected to the two ends of the connecting piece 311, and the front ends of the two spring pieces 312 are respectively in contact with the light-transmitting cover 120. The connecting piece 311 is a strip-shaped piece, and the elastic member 310 is in a long strip shape as a whole. The two spring pieces 312 enable the same elastic member 310 to have two elastic support points, and the size of a single elastic member 310 in the front-to-back direction is compressed. At the same time, the integration of the elastic support points is also realized, which simplifies the structure of the elastic member 310 and reduces the number of elastic members 310.

[0058] In some specific embodiments of the spring 312, such as Figures 2 to 4 As shown, the front part of the spring piece 312 is bent and arched forward, and the front side of the arched area abuts against the light-transmitting cover 120. More specifically, the rear end of the spring piece 312 is a straight sheet, and in the long axis direction of the connecting piece 311, the distance between the two oppositely arranged spring pieces 312 gradually increases from the back to the front, so that the elastic member 310 itself maintains a certain rigidity, thereby effectively limiting the tendency of the lens 210 to move forward.

[0059] In the specific embodiments of the spring piece 312 shown in other figures, the spring piece 312 is bent as a whole into an "S" shape and extends in the front-to-back direction to form a spring piece 312 structure similar to a compression spring.

[0060] In a specific implementation, a positioning groove 215 is provided on the front side of the base 211 , and the connecting piece 311 is placed in the positioning groove 215 to limit the displacement of the elastic member 310 in a direction perpendicular to the front-rear direction.

[0061] In some embodiments, see Figure 2 and Figure 3 A heat dissipation boss 111 is formed in the main housing 110, and the light source 220 is connected to the heat dissipation boss 111. A guide column 112 is also provided on the front side of the heat dissipation boss 111, and a guide hole 214 is provided on the lens 210 to slide forward and backward with the guide column 112. The light source board of the optical element is connected to the front side of the heat dissipation boss 111, and the main housing 110 (including the heat dissipation boss 111) is integrally formed with a material with high thermal conductivity (such as aluminum alloy) to ensure the heat dissipation requirements of the optical element.

[0062] Based on the above embodiments, see Figure 2A shaft 410 accommodating groove 113 for accommodating the shaft 410 and a cam 420 accommodating groove 114 for accommodating the cam 420 are formed on the heat dissipation boss 111 to ensure that the light source component 220 can effectively fit on the front side of the heat dissipation boss 111; and the light source component 220 cooperates with the shaft 410 accommodating groove 113 and the cam 420 accommodating groove 114 to limit the shaft 410 and the cam 420 in the radial direction of the shaft 410, thereby reducing the number of components set for positioning the shaft 410. It should be noted that since the outer diameter of the cam 420 is larger than the outer diameter of the rotating shaft 410, the depth and width of the cam 420 receiving groove 114 are also larger than the depth and width of the rotating shaft 410 receiving groove 113. In the radial direction of the rotating shaft 410, a step is formed between the cam 420 receiving groove 114 and the rotating shaft 410 receiving groove 113, which can axially limit the cam 420 and the rotating shaft 410 assembled into one.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
