The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] The utility model provides an LED lamp with adjustable light distribution. Figure 1 A cross-sectional schematic diagram of an LED lamp with adjustable light distribution according to an embodiment of the utility model is shown, Figure 1 As shown, the LED lamp with adjustable light distribution includes a lamp body 1 and a substrate 2, the substrate 2 is detachably connected to the lamp body 1, a plurality of LEDs 3 are arranged on the substrate 2, a lens 4 is arranged on one side of the substrate 2 located at the LED 3, and a movable component 5 for adjusting the relative position of the lens 4 and the LED 3 is arranged on one side of the lens 4.
[0029] Specifically, the LED 3 is fixed on the substrate 2, and the LED 3 and the substrate 2 are combined and fixed on the lamp body 1. A cover 6 is also included, and the substrate 2 is detachably connected to the lamp body 1 through the cover 6. A groove 7 is provided on the cover 6, and a sealing ring 8 is provided in the groove 7. The sealing ring 8 includes a cover waterproof ring 81 and a lens waterproof ring 82.
[0030] In this embodiment, refer to Figure 1 and Figure 2 The groove 7 is provided with two lines, and the cover waterproof ring 81 and the lens waterproof ring 82 are embedded in the groove 7. The cover waterproof ring 81 and the convex ribs provided on the lamp body 1 form a waterproof effect on the lamp body 1, and the lens waterproof ring 82 and the light-emitting surface of the lens 4 form a waterproof effect. With this design, the sealing ring 8 plays a waterproof role on the lamp body 1 as a whole, ensuring that the overall airtightness of the lamp body 1 is good, and effectively delaying the service life of the lamp.
[0031] Furthermore, the lens 4 is located on one side of the substrate 2, and the LED 3 is located in a cavity between the lens 4 and the light source substrate 2. The lens 4 includes a plurality of lens units 41 and a connecting portion 42, and the connecting portion 42 is arranged around the lens unit 41, and the lens 4 is mounted on the lamp body 1 through the connecting portion 42. The lens 4 of this design adopts a special design, and the purpose of switching the light type of the wall lamp can be achieved by only slightly adjusting the relative position of the lens 4 and the LED 3.
[0032] Specifically, refer to Figure 2 and Figure 3, a plurality of lens units 41 are arranged at intervals, the lens units 41 are arranged in a strip shape, and the inner surface section and the outer surface section of the lens unit 41 are arranged as free curves. Among them, the outer surface of the lens unit 41 is arranged as a convex light exit surface, and the inner surface of the lens unit 41 is arranged as a reverse curved light entrance surface.
[0033] In this embodiment, the lens 4 is composed of a lens unit 41 and a connecting portion 42. The lens unit 41 is a strip-shaped structure, and the connecting portion 42 is located around the lens unit 41 to fix the assembly. The cross-sections of the inner and outer surfaces of the lens unit 41 are both free curves. The outer surface is the light-emitting surface, which is convex in shape, and the inner surface is the light-entering surface, which is inverted in shape.
[0034] There is a point on the light incident surface curve where the curvature changes positively and negatively. On both sides of this point, the curvature of the curve changes positively and negatively. With this point as the boundary, the left side of this point is called the left half of the light incident surface, and the right side of this point is called the right half of the light incident surface. When LED3 and lens 4 move relative to each other in the horizontal direction, the light emitted by LED3 is incident on different positions of the free curve of the light incident surface of lens 4. If more light is incident on the left half of the free curve, the light is deflected at a large angle, forming a large-angle deflected light. If more light is incident on the right half of the free curve, the light is deflected at a small angle, forming a small-angle deflected light.
[0035] Embodiment 1:
[0036] Reference Figure 1 and Figure 3 The moving assembly 5 includes a control rod 51, a gear 52 and a rack 53. The control rod 51 is rotatably connected to the lamp body 1, the gear 52 is fixedly connected to the control rod 51, and the rack 53 is arranged on the connecting portion 42 on one side of the lens 4. The control rod 51 is used to control the coordination of the gear 52 and the rack 53 to adjust the relative position of the lens 4 and the LED 3, which is simple and efficient.
[0037] Embodiment 2:
[0038] The moving assembly 5 includes a control rod 51 and two sets of matching gears 52. The control rod 51 is rotatably connected to the lamp body 1, one set of gears 52 is fixedly connected to the control rod 51, and the other set of gears 52 is arranged on the connecting portion 42 on one side of the lens 4. The control rod 51 is used to control the matching of the two sets of gears 52 to adjust the relative position of the lens 4 and the LED 3. The matching structure of the two sets of gears 52 is stable, practical and efficient.
[0039] Furthermore, the lens 4 is provided with a plurality of positioning convex points 9, and the corresponding positions of the substrate 2 are provided with limiting grooves 10 that cooperate with the positioning convex points 9. With this design, the positioning convex points 9 on the lens 4 cooperate with the groove positions on the substrate 2 to correct the non-parallel movement of the lens 4 when moving forward and backward, and at the same time play a limiting role.
[0040] The technical solution of the utility model can adjust the relative positions of the lens 4 and the LED 3 by controlling the moving component 5, so as to switch the light pattern of the wall lamp without replacing the lens 4, which greatly reduces the potential safety hazard in operation. There is no situation in which the LED 3 is damaged due to the need to replace the lens 4, and the inventory pressure can be effectively alleviated. The light pattern switching is achieved by moving in the horizontal direction, which is convenient for terminal operation.
[0041] It should be noted that, in this embodiment, referring to Figure 3 The moving assembly 5 includes a control rod 51, a gear 52 and a rack 53. The LED 3 and the lens 4 have a mechanism similar to the gear 52 to cooperate with the control rod 51. The control rod 51 also has a mechanism similar to the gear 52 to cooperate with the lens 4. The lens 4 has a positioning protrusion 9 that cooperates with the limiting groove 10 on the substrate 2 to correct the non-parallel movement and limiting effect of the lens 4 when moving forward and backward. By rotating the control rod 51, the lens 4 is pressure-rubbed with the lens waterproof ring 82 when moving horizontally, which protects the lens 4 from waterproof failure when moving horizontally. The control rod 51 has multiple mechanisms similar to the gear 52 to drive the lens 4 to move horizontally, further correcting the asynchronous effect during movement.
[0042] In other embodiments, the specific structure of the movable component 5 can be designed according to actual needs, as long as the relative position of the lens 4 and the LED 3 can be adjusted, and no specific limitation is made here.
[0043] Further, see Figure 3 and Figure 4 , a rotating part 11 is provided at one end of the control rod 51. The control rod 51 is rotated by the rotating part 11, which is simple and efficient. In this embodiment, the rotating part 11 is configured to be in a "cross" shape, and the control rod 51 can be rotated by a screwdriver. In other embodiments, the rotating part 11 can also be configured as a handle, a rotating shaft, etc., and can be designed according to actual needs, which is not specifically limited here.
