Description

Technical Field

[0001] The utility model relates to the technical field of floodlights, and specifically, to an LED module type floodlight. Background Art

[0002] An LED module type floodlight is a lighting device with an LED as the light source, usually used for indoor and outdoor lighting and decoration, and has the characteristics of high efficiency, low energy consumption and long service life.

[0003] In order to ensure that the light projection angle of the existing LED floodlight can be adjusted, a clamping tooth and an abutting tooth are arranged between the light-emitting component and the support frame. On the basis that the angle between the light-emitting component and the support frame can be adjusted by connecting the clamping tooth and the abutting tooth, it is ensured that a self-locking is formed between the light-emitting component and the support frame after the light-emitting component and the support frame are adjusted to a proper angle.

[0004] Although this can achieve the adjustable rotation angle between the light-emitting component and the support frame and the self-locking of the adjustment result, there are still the following problems: Since there is still a possibility of rotation between the light-emitting component and the support frame, if the floodlight is collided or dropped during use, the rotation angle between the light-emitting component and the support frame may change, resulting in the deviation of the light projection position of the floodlight. Content of the Utility Model

[0005] The utility model provides an LED module type floodlight, which solves the problem that it is difficult to fix the light projection angle of the floodlight in the prior art and improves the practicability of the device.

[0006] The technical solution of the utility model is as follows:

A first locking structure for restricting the rotation between the support frame and the light-emitting component is arranged on the light-emitting component. A second locking structure for cooperating with the first locking structure is arranged on the support frame. A control structure for controlling the first locking structure to approach or move away from the second locking structure is further arranged between the light-emitting component and the support frame.

[0009] Further, the cross-section of the support frame is a "冂"-shaped structure and includes a first rotating rod and a second rotating rod.

[0012] Furthermore, the control structure includes a control rod, a limiting bolt is fixed on the second spring sheet, the first connecting plate and the first spring sheet are both provided with connecting holes slidably connected to the limiting bolt, the limiting bolt is fixed with a rotating hole rotatably connected to the control rod at the end away from the first spring sheet, a limiting member is fixed at the end of the control rod, the limiting member is rotatably connected to the rotating hole, and the limiting member abuts against the first spring sheet.

[0013] Furthermore, the limiting member is provided with a first limiting surface and a second limiting surface, and the distance between the first limiting surface and the rotation center of the rotating hole is greater than the distance between the second limiting surface and the rotation center of the rotating hole.

[0014] Furthermore, a plurality of heat dissipation fins are fixed to the end of the light emitting component close to the power supply component, and the cross section of each heat dissipation fin is an isosceles trapezoidal structure.

[0015] The working principle and beneficial effects of the utility model are:

The utility model has a more stable structure and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0028] As Figure 2 to Figure 6 shown, this embodiment proposes an LED module type floodlight, and its structure includes a light-emitting component 1. The power supply component 2 in this embodiment is fixedly arranged on the light-emitting component 1 to supply power to the light-emitting component 1. The support frame 3 is rotatably arranged on the light-emitting component 1. The first locking structure is arranged on the light-emitting component 1 to limit the rotation of the support frame 3 and the light-emitting component 1. The second locking structure is arranged on the support frame 3 to cooperate with the first locking structure. The control structure is arranged between the light-emitting component 1 and the support frame 3 to control the first locking structure to approach the second locking structure or control the first locking structure to move away from the second locking structure. The light-emitting component in this embodiment is an LED lamp component of the LED module type. Among them, the LED lamp component is a prior art and will not be elaborated in this embodiment.

[0029] A number of heat dissipation fins 13 in this embodiment are fixedly arranged at the end of the light-emitting component 1 close to the power supply component 2. The cross-section of each heat dissipation fin 13 is an isosceles trapezoid structure, which is used to make the heat dissipation fin 13 not easy to bend relative to the light-emitting component 1 and increase the stability of this structure. The design of the heat dissipation fin 13 increases the external leakage surface area of the light-emitting component 1, making the heat dissipation ability of the light-emitting component 1 stronger.

[0030] The cross-section of the support frame 3 in this embodiment is a "冂" - shaped structure and includes a first rotating rod 31 and a second rotating rod 32. A connecting rod 33 is fixed between the first rotating rod 31 and the second rotating rod 32. Such a design enables the support frame 3 to complete the adjustment of the angle of the installation and light projection position of the light-emitting component 1 with the smallest manufacturing volume. A first connecting plate 14 and a second connecting plate 15 are fixedly arranged at both ends of the light-emitting component 1. A first rotating member 11 is fixedly arranged on the first connecting plate 14, and a second rotating member 12 is fixedly arranged on the second connecting plate 15. The first rotating rod 31 is rotatably connected to the first rotating member 11, and the second rotating member 12 is rotatably connected to the second rotating rod 32. Such a design ensures that the angle between the support frame 3 and the light-emitting component 1 is adjustable, and the light projection position can be changed by rotating the support frame 3 through the light-emitting component 1.

[0031] In this embodiment, the first spring sheet 41 and the second spring sheet 42 are fixedly arranged on both sides of the connecting rod 33, the first spring sheet 41 is arranged on one side of the first connecting plate 14, and a distance is provided between the other end of the first spring sheet 41 and the first connecting plate 14, the second spring sheet 42 is arranged on the other side of the first connecting plate 14, and a distance is provided between the other end of the second spring sheet 42 and the first connecting plate 14, and the second locking structure includes a first locking member 411 and a second locking member 421, the first locking member 411 is fixedly arranged on one side of the first spring sheet 41 close to the first connecting plate 14, and the second locking member 421 is fixedly arranged on one side of the second spring sheet 42 close to the first connecting plate 14. Under normal conditions, the elasticity of the first spring sheet 41 and the second spring sheet 42 ensures that there is a certain distance between the first spring sheet 41 and the second spring sheet 42 and the first connecting plate 14, so that the first locking member 411 and the second locking member 421 are away from the first spring sheet 41, so that under normal conditions, the support frame 3 rotates relative to the light-emitting assembly 1.

[0032] In this embodiment, the outer surface of the first locking member 411 is a cylindrical structure, the mounting groove 4111 is provided on the first locking member 411, a plurality of first mounting teeth 4112 are fixedly provided on the inner wall of the mounting groove 4111, and the second locking member 421 has the same structure as the first locking member 411. The first locking structure includes a first gear 141 and a second gear 142, which are respectively fixedly provided on both sides of the first rotating rod 31. The first gear 141 meshes with the first mounting teeth 4112 on the first locking member 411, and the second gear 142 meshes with the first mounting teeth 4112 on the second locking member 421. With such a design, when the support frame 3 is rotated to a suitable angle relative to the light-emitting component 1, the first gear 141 on the first locking member 411 meshes with the first mounting teeth 4112, so that the support frame 3 cannot rotate relative to the light-emitting component 1.

[0033] The control structure in this embodiment includes a control rod 5, a limiting bolt 6 fixedly arranged on the second elastic sheet 42, and a connecting hole 143 arranged on the first connecting plate 14 and the first elastic sheet 41, which are slidably connected with the limiting bolt 6. The rotating hole 61 is fixedly arranged at the end of the limiting bolt 6 away from the first elastic sheet 41, and is rotatably connected with the control rod 5. The limiting member 51 is fixedly arranged at the end of the control rod 5, the limiting member 51 is rotatably connected with the rotating hole 61, and the limiting member 51 abuts against the first elastic sheet 41. When the control rod 5 rotates to drive the limiting member 51 to rotate, the limiting bolt 6 is driven to slide by the abutment of the limiting member 51 at different positions with the first elastic sheet 41, so that the first gear 141 is meshed with the first mounting tooth 4112 or the first gear 141 is away from the first mounting tooth 4112, so that the support frame 3 can achieve two states of rotation relative to the light-emitting component 1 and self-locking relative to the light-emitting component 1.

[0034] In this embodiment, the first limiting surface 511 and the second limiting surface 512 are arranged on the limiting member 51, and the distance between the first limiting surface 511 and the rotation center of the rotating hole 61 is greater than the distance between the second limiting surface 512 and the rotation center of the rotating hole 61. When the first limiting surface 511 abuts against the first spring sheet 41, since the first limiting surface 511 is far away from the center of the rotating hole 61, the first spring sheet 41 and the second spring sheet 42 are driven to move closer to the first connecting plate 14, so that the rotation between the light-emitting component 1 and the support frame 3 is stopped; and when the second limiting surface 512 contacts the first spring sheet 41, since the second limiting surface 512 is close to the center of the grasping hole, the first spring sheet 41 and the second spring sheet 42 are both moved away from the first connecting plate 14, so that the light-emitting component 1 can rotate relative to the support frame 3. The first limiting surface 511 and the second limiting surface 512 abut against the first spring sheet 41, so that the control rod 5 is not easy to rotate when abutting.

[0035] The working process of this embodiment is as follows: when it is necessary to adjust the angle between the light-emitting component 1 and the support frame 3, first rotate the control lever 5 to make the second limiting surface 512 contact with the first spring piece 41. At this time, the first spring piece 41 and the second spring piece 42, under the action of their own elastic force, make the first gear 141 and the second gear 142 move away from the first mounting tooth 4112 wheel, and then adjust the rotating support frame 3 to ensure that the light-emitting angle of the light-emitting component 1 is at a suitable position. Finally, rotate the control lever 5 in the opposite direction to make the first limiting surface 511 contact with the first spring piece 41, so that the first gear 141 and the second gear 142 are both engaged with the first mounting tooth 4112 wheel, ensuring that the rotation angle of the light-emitting component 1 and the support frame 3 is fixed.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
