Description

Technical Field

[0001] The present disclosure relates to the technical field of lighting, and in particular to an omnidirectionally adjustable lighting device and a projection lamp. Background Art

[0002] Currently, lighting fixtures adjust their illumination direction by adjusting the radiator, which is connected to a wire. When rotating the illumination direction, a stopper is required to prevent the wire connected to the radiator from getting tangled or broken. However, it is impossible to achieve full adjustment of the illumination direction of the lighting fixture.

[0003] Existing technology, such as Chinese patent number CN 211716377 U, discloses a lighting lamp with a 360-degree adjustment mechanism. By moving the front ring of the lamp body, it is placed in a floating state in the spherical space formed between the fixed surface ring and the lamp body cover, thereby ensuring that the space inside the front ring of the lamp body and the fixed surface ring can rotate arbitrarily around the center of the sphere, thereby achieving free adjustment of the lamp at various angles on the circumference and ensuring that the optical components in the front ring of the lamp body can illuminate without blind spots when powered on.

[0004] Although the above-mentioned 360-degree adjustment mechanism realizes 360-degree illumination without blind spots, the radiator is still installed with the front ring of the lamp body through the connecting seat, so when the front ring of the lamp body is rotated to adjust the illumination angle, the radiator rotates accordingly. Since the radiator is relatively heavy, the damping force is large, making the adjustment of the lamp difficult, and even causing the problem of damping failure, and the reliability of use is poor. Utility Model Content

[0011] In one embodiment, the omnidirectional adjustable lighting device further includes a damping assembly, and the damping assembly is arranged between the fixed surface ring and the spherical rotating adjustable surface ring.

[0012] In one embodiment, the damping assembly includes a plurality of damping protrusions, and each of the damping protrusions is arranged at intervals on the fixed surface ring.

[0013] In one embodiment, the damping bumps are rubber damping bumps, silicone damping bumps, or polyurethane damping bumps.

The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0033] like Figures 1 to 5As shown, an omnidirectional adjustable lighting device 10 of an embodiment includes a shell 400, a heat sink 500, a light source assembly 600 and a fixed surface ring 200. The light source assembly 600 includes a lens 610 and a light source accessory 620. A accommodating cavity 410 is formed in the shell 400. The light source accessory 620 is arranged in the accommodating cavity 410. The heat sink 500 is arranged in the light source accessory 620. The heat sink 500 is formed with a snap-fit ​​groove 510. The fixed surface ring 200 is arranged in the snap-fit ​​groove 510. The omnidirectional adjustable lighting device 10 also includes a rotary adjustment surface ring. The rotary adjustment surface ring is a spherical rotary adjustment surface ring 100. The spherical rotary adjustment surface ring 100 is rotatably arranged on the fixed surface ring 200. The spherical rotary adjustment surface ring 100 is formed with an accommodating cavity 110. The lens 610 is arranged in the accommodating cavity 110.

[0034] It can be understood that since the light source accessory 620 is arranged in the accommodating cavity 410 of the shell 400, and the radiator 500 is arranged in the light source accessory 620, the radiator 500 is fixedly installed in the accommodating cavity 110; since the fixed surface ring 200 is arranged in the snap-fit ​​groove 510 of the radiator 500, the fixed surface ring 200 can be fixedly installed on the radiator 500, so that the radiator 500 and the fixed surface ring 200 are fixedly installed in the accommodating cavity 110.

[0035] It can be understood that since the rotary adjustment surface ring is a spherical rotary adjustment surface ring 100, the spherical rotary adjustment surface ring 100 can realize all-round adjustment of the projection direction of the lighting device 10; since the lens 610 is arranged in the accommodating cavity 110, the spherical rotary adjustment surface ring 100 is rotatably arranged on the fixed surface ring 200, so that the lens 610 can rotate all-round around the fixed surface ring 200 along with the spherical rotary adjustment surface ring 100, thereby realizing the adjustability of the all-round projection of the light source accessory 620 through the lens 610; and since the lens 610 is lighter than the radiator 500, when the direction of the spherical rotary adjustment surface ring 100 is rotated to adjust, the damping force of the rotation is small, which is convenient for the adjustment of the lamp and avoids the occurrence of damping failure, thereby realizing all-round lighting adjustment of the projection lamp and having good reliability in use.

[0036] It can also be understood that the radiator 500 is provided on the light source accessory 620, so that when the light source accessory 620 is in use, the fixedly installed radiator 500 can dissipate the heat of the light source accessory 620 as quickly as possible, ensuring the normal use of the light source accessory 620, thereby increasing the service life of the projection lamp.

[0037] In one embodiment, the fixed face ring 200 is welded to the heat sink 500, and the outer wall of the heat sink 500 abuts the inner wall of the accommodating cavity 410. It can be understood that the fixed face ring 200 is welded to the heat sink 500, so that the fixed face ring 200 and the heat sink 500 are an integrated structure, and the outer wall of the heat sink 500 abuts the inner wall of the accommodating cavity 410, so that the heat sink 500 is in contact with the housing 400. Since the housing 400 is in contact with the external air, the heat generated when the light source accessory 620 is in use can be conducted to the heat sink 500 through the fixed face ring 200, and then conducted to the housing 400 by the heat sink 500, and finally dissipated into the air, ensuring that the heat sink 500 can dissipate the internal heat outward through the housing 400, thereby ensuring that the heat sink 500 is fixed and does not affect the heat dissipation effect of the projection lamp.

[0038] In one embodiment, the spherical rotating adjustment surface ring 100 and the fixed surface ring 200 are spherical structures, and the outer wall of the spherical rotating adjustment surface ring 100 rotates and abuts against the inner wall of the fixed surface ring 200. It can be understood that the spherical rotating adjustment surface ring 100 and the fixed surface ring 200 are spherical structures to ensure that the outer wall diameter of the spherical rotating adjustment surface ring 100 and the inner wall diameter of the fixed surface ring 200 are compatible; because the outer wall of the spherical rotating adjustment surface ring 100 rotates and abuts against the inner wall of the fixed surface ring 200, the spherical rotating adjustment surface ring 100 can rotate in all directions relative to the fixed surface ring 200, thereby achieving all-round lighting adjustment of the projector.

[0039] In one embodiment, a light exit hole 120 is formed in the middle of the spherical rotating adjustment ring 100. A lens 610 is protruded from the light exit hole 120 on a side facing away from the light source assembly 620. Light from the light source assembly 620 passes through the lens 610 and exits from the light exit hole 120. It is understood that because the lens 610 is protruded from the light exit hole 120 on a side facing away from the light source assembly 620, on the one hand, when light from the light source assembly 620 is emitted, the light passes through the lens 610 and can exit from the light exit hole 120, thereby ensuring the effectiveness of light emission. On the other hand, compared to a case where the heat sink 500 is mounted on the spherical rotating adjustment ring 100, the lens 610 is lighter in weight, resulting in less damping force. This reduces the possibility of damping failure when the spherical rotating adjustment ring 100 is rotated to adjust the angle, thereby achieving all-round lighting adjustment of the projector lamp and improving reliability.

[0040] In one embodiment, the omnidirectionally adjustable lighting device 10 further includes a damping assembly disposed between the fixed surface ring 200 and the spherical rotating adjustable surface ring 100. It will be appreciated that the damping assembly disposed between the fixed surface ring 200 and the spherical rotating adjustable surface ring 100 makes the spherical rotating adjustable surface ring 100 more stable and controllable during rotation, reduces shaking or instability of the lens 610 during rotation, and thereby improves the controllability of adjusting the illumination direction of the projector.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, the damping assembly includes multiple damping protrusions 310, each of which is spaced apart on the fixed surface ring 200. It will be appreciated that the multiple damping protrusions 310 spaced apart on the fixed surface ring 200 improve the stability of the damping assembly. On the one hand, when the multiple damping protrusions 310 rotate in contact with the spherical rotating adjustment surface ring 100, the friction generated provides resistance to the rotation of the spherical rotating adjustment surface ring 100, thereby slowing down the rotation of the spherical rotating adjustment surface ring 100 and making the rotation process smoother. On the other hand, the multiple damping protrusions 310 provide a sense of positioning, allowing the operator to more accurately perceive and control the rotation angle and position of the spherical rotating adjustment surface ring 100. By adding multiple damping protrusions 310, the shaking and instability of the spherical rotating adjustment surface ring 100 during rotation is reduced, making it easier to adjust the angle of the projector and thus achieving full adjustment of the projection direction.

[0042] In one embodiment, the damping bumps 310 are rubber, silicone, or polyurethane damping bumps. As will be appreciated, rubber, silicone, and polyurethane have excellent damping properties and wear resistance, effectively increasing the force applied during adjustment of the damping bumps 310 and ensuring smooth rotation of the spherical rotary adjustment ring 100. When selecting the damping bumps 310, consideration must be given to their damping coefficient, wear resistance, and corrosion resistance. Therefore, those skilled in the art can select suitable damping bumps 310 based on actual circumstances.

[0043] In one embodiment, the spherical rotating adjustment surface ring 100 slides against the inner wall of the fixed surface ring 200, ensuring the flatness of the inner surface of the fixed surface ring 200, making it easy to install the spherical rotating adjustment surface ring 100 in the fixed surface ring 200, and ensuring the reliability of the installation, so as to ensure that when the outer wall of the spherical rotating adjustment surface ring 100 contacts the inner wall of the fixed surface ring 200, the wear of the fixed surface ring 200 when contacting the spherical rotating adjustment surface ring 100 can be reduced.

[0044] In one embodiment, the spherical rotating adjustment ring 100 is an aluminum alloy, stainless steel, or titanium alloy spherical rotating adjustment ring. It will be appreciated that, due to the excellent strength and wear resistance of aluminum alloy, stainless steel, and titanium alloy, the spherical rotating adjustment ring 100 can maintain contact strength with the fixed ring 200 when in contact, improving the secure installation of the two. Since the spherical rotating adjustment ring 100 and the fixed ring 200 frequently rotate in contact, the aluminum alloy, stainless steel, and titanium alloy can reduce wear during contact, thereby increasing the service life of the omnidirectionally adjustable lighting device 10. Therefore, those skilled in the art can select an appropriate spherical rotating adjustment ring 100 based on actual circumstances.

[0045] Similarly, in one embodiment, the fixed face ring 200 is an aluminum alloy fixed face ring, a stainless steel fixed face ring, or a titanium alloy fixed face ring. As will be appreciated, aluminum alloy, stainless steel, and titanium alloy have excellent strength and wear resistance, thereby increasing the service life of the fixed face ring 200 while also being less prone to deformation, thereby ensuring secure installation of the fixed face ring 200. Those skilled in the art can select an appropriate fixed face ring 200 based on actual circumstances.

[0046] like Figure 4 As shown, in one embodiment, the omnidirectional adjustable lighting device 10 further includes a protective mask 700, which is located above the spherical rotating adjustable surface ring 100. The protective mask 700 is provided with a clearance hole 710 corresponding to the spherical rotating adjustable surface ring 100, and the protective mask 700 is detachably mounted on the housing 400. It is understood that since the protective mask 700 is detachably mounted on the housing 400, the removal and assembly of the protective mask 700 is facilitated. Furthermore, since the protective mask 700 is located above the spherical rotating adjustable surface ring 100, it can prevent the lens 610 installed in the spherical rotating adjustable surface ring 100 from falling, thereby ensuring the reliability of the overall installation. Furthermore, since the protective mask 700 is provided with a clearance hole 710 corresponding to the spherical rotating adjustable surface ring 100, the protective mask 700 is prevented from interfering with the spherical rotating adjustable surface ring 100 and the lens when the spherical rotating adjustable surface ring 100 rotates, thereby improving the reliability of the rotation of the spherical rotating adjustable surface ring 100.

[0047] The present disclosure further provides a projection lamp comprising the omnidirectional adjustable lighting device 10 described in any one of the above embodiments.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1) Since the light source accessory 620 is arranged in the accommodating cavity 410 of the shell 400, and the radiator 500 is arranged on the light source accessory 620, the radiator 500 is fixedly installed in the accommodating cavity 110; since the fixed surface ring 200 is arranged in the snap-fit ​​groove 510 of the radiator 500, the fixed surface ring 200 can be fixedly installed on the radiator 500, thereby realizing that the radiator 500 and the fixed surface ring 200 are fixedly installed in the accommodating cavity 110.

[0050] 2) Since the rotary adjustment surface ring is a spherical rotary adjustment surface ring 100, the spherical rotary adjustment surface ring 100 can realize all-round adjustment of the projection direction of the lighting device 10; since the lens 610 is arranged in the accommodating cavity 110, the spherical rotary adjustment surface ring 100 is rotatably arranged on the fixed surface ring 200, so that the lens 610 can rotate all-round around the fixed surface ring 200 along with the spherical rotary adjustment surface ring 100, thereby realizing the adjustability of the all-round projection of the light source accessory 620 through the lens 610; and since the lens 610 is lighter than the radiator 500, when the direction of the spherical rotary adjustment surface ring 100 is rotated to adjust, the damping force of the rotation is small, which is convenient for the adjustment of the lamp and avoids the occurrence of damping failure, thereby realizing all-round lighting adjustment of the projection lamp and having good reliability in use.

[0051] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
