Description

Technical Field

[0001] The present invention relates to the field of lighting devices, and particularly to an adjustable eccentric embedded spotlight. Background Art

[0002] An embedded spotlight is a lighting fixture embedded in a ceiling. Generally, an embedded spotlight includes a lamp body and a reflecting cup rotatably arranged on the lamp body. The light emitted by the lamp body is converged by the reflecting cup and then emitted. By rotating the reflecting cup, the light-emitting direction of the embedded spotlight can be adjusted.

[0003] When adjusting the light-emitting direction of the embedded spotlight, as the reflecting cup rotates, a part of the light emitted by the lamp body cannot enter the reflecting cup, and thus cannot provide illumination for the user, resulting in a decrease in the luminous flux of the reflecting cup, which not only wastes the light emitted by the light-emitting component but also affects the lighting effect of the embedded spotlight. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide an adjustable eccentric embedded spotlight to solve one or more problems in the prior art.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] An adjustable eccentric embedded spotlight includes a first reflecting cup and a bracket that are rotatably engaged. The axis of rotation of the bracket relative to the first reflecting cup is perpendicular to the axis of the first reflecting cup. A lamp body for emitting light is movably arranged on the bracket so that the light emitted by the lamp body points to the proximal end of the first reflecting cup.

[0007] Further, the lamp body includes a light source and a second reflecting cup. The second reflecting cup is used for gathering the light emitted by the light source and guiding the light of the light source to the proximal end of the first reflecting cup.

[0008] Further, the lamp body includes a housing and a base. The housing is provided with a groove for accommodating the light source and the second reflecting cup. The base is connected to the notch of the groove to lock the light source and the second reflecting cup.

[0009] Further, the base and the housing are fixedly connected or detachably connected.

[0010] Further, a first avoiding portion is provided on the proximal end of the first reflecting cup to facilitate the light of the light-emitting component to enter the first reflecting cup.

[0011] Further, it further includes a first ring body. The first reflecting cup is connected to the first ring body, and the bracket is rotatably mounted on the first ring body.<L

[0012] Further, a second ring body is provided on the first ring body. The bracket is rotatably mounted inside the second ring body. The lamp body is slidably engaged with the bracket. A second avoidance portion is provided on the second ring body for the lamp body to slide relative to the bracket.

[0013] Further, a first hole is formed in the bracket, and a first connecting member is slidably disposed in the first hole. The first connecting member is connected to the lamp body.

[0014] Further, the bracket is provided with a second hole, and a third hole is formed in the second ring body. A second connecting member is passed through between the second hole and the third hole. The bracket and the second ring body are rotatably engaged through the second connecting member.

[0015] Further, the second ring body is detachably connected with a cover body, and the cover body covers the second connecting member.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0017] (1) After the first reflecting cup rotates relative to the lamp body, the position of the lamp body on the bracket is adjusted, so that the light emitted by the lamp body points to the first reflecting cup. The first reflecting cup can gather and emit the light emitted by the lamp body, increase the luminous flux of the first reflecting cup, reduce the waste of the light emitted by the lamp body, and ensure good lighting effect of the embedded spotlight after the first reflecting cup rotates.

[0018] (2) By using the second reflecting cup, the light emitted by the light source can be gathered in advance, and the light emitted by the light source is guided by the second reflecting cup to the first reflecting cup, which can increase the luminous flux of the first reflecting cup and reduce the waste of the light emitted by the lamp body.

[0019] (3) A first avoidance portion is provided on the first reflecting cup. After the bracket rotates and the lamp body moves relative to the bracket, the light emitted by the lamp body points to the first reflecting cup. The first avoidance portion is provided to facilitate the light emitted by the lamp body to enter the first reflecting cup, thereby increasing the luminous flux in the first reflecting cup.

[0020] (4) A second avoidance portion is provided on the second ring body. After the bracket rotates, the lamp body slides relative to the bracket. By providing the second avoidance portion, the second ring body can be prevented from interfering with the sliding of the lamp body. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the following further details an adjustable eccentric embedded spotlight proposed by the present invention in conjunction with the attached drawings and specific implementation manners. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the attached drawings are in a very simplified form and all use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the implementation manners of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and understandable, please refer to the attached drawings. It should be noted that the structures, scales, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed by the present invention.

[0028] In order to more clearly describe the above-mentioned embedded spotlight, the present invention defines the terms "proximal end" and "distal end". Specifically, the "proximal end" represents the end that the light emitted by the lamp body passes through first; the "distal end" represents the end that the light emitted by the lamp body passes through later. Taking Figure 3 or Figure 4 as an example, the upper side in the figure is the proximal end, and the lower side in the figure is the distal end.

[0029] Embodiment

[0030] Please refer to Figures 1 to 4, the present application provides an adjustable eccentric embedded spotlight, which includes a first ring body 1 and a second ring body 2 that are detachably connected. The axis of the first ring body 1 coincides with the axis of the second ring body 2. The first ring body 1 is integrally formed with a first reflector cup 11, and the axis of the first reflector cup 11 coincides with the axis of the first ring body 1. A bracket 4 is rotatably mounted on the second ring body 2, and the rotation axis of the bracket 4 is perpendicular to the axis of the second ring body 2. A lamp body 5 is slidably provided on the bracket 4. A light source 52 for emitting light is installed in the lamp body 5. The sliding direction of the lamp body 5 is perpendicular to the rotation axis between the bracket 4 and the second ring body 2, and the sliding direction of the lamp body 5 is also perpendicular to the axis of the lamp body 5.

[0031] The lamp body 5 includes a housing 51 and an annular base body 54. A receiving groove (not shown in the figure) for receiving the light source 52 is formed on the far end surface of the housing 51. A second reflector cup 53 is further provided in the receiving groove. The second reflector cup 53 is used to guide the light emitted by the lamp body 5 to be emitted along the axis of the lamp body 5. The proximal end of the second reflector cup 53 presses the light source 52 against the bottom of the receiving groove. The base body 54 is located at the mouth of the receiving groove and is bolted to the housing 51. The base body 54 presses against the distal end of the second reflector cup 53 to lock the position of the second reflector cup 53. In addition, the base body 54 can also be fixed to the housing 51 by bonding.

[0032] Please refer to Figure 3 and Figure 4 , the lamp body 5 is slidably arranged on the bracket 4 through the base body 54. Two first holes 42 are formed on the bracket 4. The length directions of the two first holes 42 are parallel to each other. A first connecting member (not shown in the figure) is slidably arranged in the first hole 42. The first connecting member is a bolt. The proximal end of the bolt is a threaded end. The proximal end of the bolt passes through the first hole 42 and is bolted to the base body 54. When the proximal end of the bolt is bolted to the base body 54, the cap body of the bolt presses against the distal end surface of the bracket 4. The first connecting member can be used to slidably mount the lamp body 5 on the bracket 4 and prevent the lamp body 5 from detaching from the bracket 4.

[0033] Please refer to Figure 3 and Figure 4 , two support plates 41 are formed on the distal end surface of the bracket 4. Second holes 43 are formed on both support plates 41. The second holes 43 are threaded holes. Two third holes 23 are formed on the side wall of the second ring body 2. The two third holes 23 are symmetric about the axis of the second ring body 2. When the bracket 4 is installed in the second ring body 2, the two second holes 43 are respectively aligned with one third hole 23. A second connecting member (not shown in the figure) is passed through between the second hole 43 and the adjacent first hole 42. The second connecting member is a bolt. The threaded end of the second connecting member passes through the third hole 23 and is in threaded cooperation with the second hole 43. The bracket 4 is rotatably mounted on the second ring body 2 through the two support plates 41.

[0034] Please refer to Figure 3 and Figure 4, two cover bodies 24 are detachably connected to the outer side surface of the second ring body 2. The two cover bodies 24 respectively cover the two second connecting members to prevent the second connecting members from falling off. Three second clamping blocks 241 are formed on the cover body 24, and second clamping grooves are formed on the outer side surface of the second ring body 2. The second clamping blocks 241 and the second clamping grooves form a cantilever clamping structure. By fitting the second clamping blocks 241 into the second clamping grooves, the cover body 24 can be detachably connected to the outer side surface of the second ring body 2.

[0035] Specifically, for the second clamping block 241 and the second clamping groove, the cantilever clamping structure means that the second clamping block 241 is made of a material with resilience, such as plastic. The second clamping block 241 includes an integrally formed block body and a protruding portion. When the second clamping block 241 cooperates with the second clamping groove, the protruding portion is embedded in the second clamping groove. If the second clamping block 241 needs to be taken out, it is necessary to force the block body to deform so that the protruding portion can smoothly slide out of the second clamping groove.

[0036] When the axis of the lamp body 5 coincides with the axis of the first reflecting cup 11, the axis of rotation of the bracket 4 relative to the second ring body 2 coincides with the axis of the lamp body 5; the direction of sliding of the lamp body 5 relative to the bracket 4 is perpendicular to the axis of the first reflecting cup 11.

[0037] Please refer to Figures 2 to 4 , when the bracket 4 deflects, the lamp body 5 slides on the bracket 4 and will be interfered by the side wall of the second reflecting cup 53. Therefore, a second avoiding portion 21 is formed at the proximal end of the second reflecting cup 53 to avoid the lamp body 5, which can increase the sliding range of the lamp body 5 and ensure that after the bracket 4 deflects, the lamp body 5 can slide to the position where the axis of the lamp body 5 points to the proximal end of the first reflecting cup 11.

[0038] Please refer to Figures 2 to 4 , when the axis of the lamp body 5 points to the proximal end of the first reflecting cup 11, a part of the light emitted by the lamp body 5 will fall on the outer side surface of the first reflecting cup 11. In order to increase the luminous flux of the first reflecting cup 11, the proximal end of the first reflecting cup 11 is inclined to form a first avoiding portion 111, which can increase the opening of the proximal end of the first reflecting cup 11 to facilitate the light emitted by the lamp body 5 to enter the first reflecting cup 11.

[0039] Please refer to Figure 3 and Figure 4 , three first clamping blocks 112 are formed on the outer side surface of the first reflecting cup 11, and three first clamping grooves are formed on the inner wall of the second ring body 2. The first clamping blocks 112 and the first clamping grooves form a cantilever clamping structure with reference to the second clamping blocks 241 and the second clamping grooves. By fitting the first clamping blocks 112 into the first clamping grooves, the detachable connection between the first ring body 1 and the second ring body 2 can be realized.

[0040] Please refer to Figure 3 and Figure 4, a third ring body 3 is further sleeved outside the second ring body 2. Three third card slots are formed on the inner wall of the third ring body 3, and three third card blocks 22 are formed on the side surface of the second ring body 2. The third card block 22 and the third card slot form a cantilevered clamping structure with the second card block 241 and the second card slot. The detachable connection between the second ring body 2 and the third ring body 3 can be realized through the engagement of the third card block 22 and the third card slot.

[0041] Please refer to Figure 3 , a circular flanging 31 is formed at the distal end of the third ring body 3, and an elastic shrapnel 32 is detachably connected to the outer side surface of the third ring body 3.

[0042] Working principle:

[0043] After the embedded spotlight is installed, when the light output direction needs to be adjusted, the second ring body 2 can be controlled to rotate relative to the lamp body 5 to adjust the light output direction of the embedded spotlight. Subsequently, the first ring body 1 is removed. The operator passes a tool or directly puts a hand through the third ring body 3 and extends into the second ring body 2 to slide the lamp body 5. The position of the lamp body 5 is adjusted so that when the first ring body 1 is reinstalled on the second ring body 2, the axis of the lamp body 5 points to the proximal opening of the first reflector 11. Then the light emitted by the lamp body 5 can smoothly converge into the first reflector 11. This method increases the luminous flux of the first reflector 11, reduces the waste of the light emitted by the lamp body 5, and ensures good lighting effects of the embedded spotlight after the first reflector 11 rotates.

[0044] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0045] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
