Description

Technical Field

[0001] This utility model belongs to the field of lighting fixture technology, and in particular to a lamp with an adjustable lamp head angle. Background Technology

[0002] Lighting fixtures are a general term for lighting tools. They are devices that can transmit, distribute, and change the distribution of light sources and are widely used in daily life.

[0003] However, in most existing technologies, the lamp head and the mounting bracket are fixedly connected, and the lamp head angle is not adjustable, causing great inconvenience to users. Even if some lamps have lamp head adjustment functions, their structures are complex, the production processes are numerous, and the manufacturing costs are high.

[0004] For example, in the utility model patent with publication number CN218544142U, the lamp head angle of the lighting lamp is adjusted by means of the lamp head bracket, bolts, positioning rubber parts, and wing nuts. This not only has a complex structure and high manufacturing cost, but also requires cumbersome installation. Based on this, we propose a lighting fixture with an adjustable lamp head angle to solve this problem. Summary of the Invention

[0005] In view of this, the present invention provides a lamp with an adjustable lamp head angle to solve the above problems.

[0006] A lamp holder with an adjustable lamp head angle includes a lamp holder, a lamp body assembly placed on the lamp holder, and a rotating fixing member passing through the lamp holder and the lamp body assembly. The lamp holder includes a lamp holder housing, which includes a lamp holder body, a mounting surface on the lamp holder body, and a first insertion hole formed on the mounting surface for the rotating fixing member to pass through. The mounting surface is an inwardly concave hemispherical surface, and its cross-section along the alignment direction of the lamp holder body and the mounting surface is a semi-circular arc. The central axis of symmetry of this semi-circular arc intersects with the semi-circular arc to form an intersection point. The first insertion hole is located on the side of the mounting surface and is spaced apart from the intersection point. The lamp body assembly includes a lamp housing assembly and a light source assembly located within the lamp housing assembly. The lamp housing assembly includes a lower lamp housing and an upper lamp housing connected to the lower lamp housing. The lower lamp housing includes a lamp housing body and a second insertion hole disposed on the lamp housing body. The lamp housing body has a semi-circular cross-section along the direction of the lamp holder body and the mounting surface. The second insertion hole is disposed on the lamp housing body and is spaced apart from the intersection of the lamp housing body's central axis of symmetry with the lamp housing body. The rotating fastener includes a screw passing through the first insertion hole and the second insertion hole, a fixing sleeve sleeved over the screw, and a sealing ring located between the screw and the fixing sleeve. The screw and the fixing sleeve are disposed opposite to each other, and the screw and the fixing sleeve cooperate to fix the lamp body assembly to the lamp holder. The sealing ring is made of an elastic material.

[0007] Furthermore, the lamp holder also includes a cover connected to the lamp holder housing. The cover is used to support the lamp holder housing and is a circular plate. The cover includes two receiving grooves formed on the cover, two fixing components respectively mounted on each receiving groove, and a plugging protrusion located on the cover. The cover can be fixedly connected to the lamp holder housing by screws.

[0008] Furthermore, the lamp holder body is a cylindrical structure with a sealing edge around its perimeter to form a sealed space with the cover to isolate external dust. The lamp holder body also includes an insertion groove on the sealing edge to facilitate quick positioning of the lamp holder housing on the cover.

[0009] Furthermore, each of the fixing components includes a magnetic suction member mounted on the receiving groove and a fastening cover clamped to the outside of the magnetic suction member. The magnetic suction member is used to attract and fix the lamp with adjustable lamp head angle to a magnetic wall or ceiling to facilitate the installation of the lamp. The fastening cover is used to protect and install the magnetic suction member and covers the outside of the magnetic suction member.

[0010] Furthermore, the outer surface of the lamp housing body is a hemispherical surface, and the shape of the outer surface of the lamp housing body is adapted to the shape of the mounting surface, and the lamp housing body is tightly fitted to the mounting surface.

[0011] Furthermore, the second socket is located at the midpoint between the outer edge of the lamp housing body and the center of the housing, and is correspondingly positioned to the first socket.

[0012] Furthermore, the lamp with adjustable lamp head angle also includes a lampshade assembly connected to the lamp body assembly for protecting the light source assembly. The lampshade assembly includes a dustproof plate connected to the upper lamp housing and a waterproof cover connected to the dustproof plate. The dustproof plate is used to facilitate the entry of external dust into the upper lamp housing, and the waterproof cover is used to prevent external water from entering the upper lamp housing. Both the dustproof plate and the waterproof plate are fixed to the upper lamp housing by adhesive.

[0013] Furthermore, the fixing sleeve is a hollow cylindrical sleeve with one end open, and the outer ring radius of the cylindrical sleeve is approximately equal to the hole radius of the first insertion hole and the hole radius of the second insertion hole, so that the screw and the fixing sleeve are precisely fitted and fixed in the first insertion hole and the second insertion hole.

[0014] Furthermore, the light source assembly includes a charging plug, a circuit board connected to the charging plug, a power supply connected to the circuit board, and a light source connected to the power supply.

[0015] Furthermore, the distance between the second socket and the intersection of the central axis of symmetry of the lamp housing body and the lamp housing body is equal to the distance between the first socket and the intersection of the axis of symmetry.

[0016] Compared with existing technologies, the adjustable lamp head angle lamp provided by this utility model uses a rotating fixing component to fix the lamp body assembly to the lamp holder. The rotating fixing component includes a screw passing through the first and second insertion holes, a fixing sleeve sleeved over the screw, and a sealing ring made of elastic material such as plastic located between the screw and the fixing sleeve. The screw and the fixing sleeve are arranged opposite each other to fix the lower lamp housing to the mounting surface. The user can manipulate the lower lamp housing according to their needs, causing the sealing ring to elastically deform and allowing the lower lamp housing to rotate around the central axis of the screw and the fixing sleeve to adjust the illumination position of the light source assembly. This utility model uses only the screw, the fixing sleeve, and the sealing ring to fix the lower lamp housing to the mounting surface, and the position of the lower lamp housing on the mounting surface can be adjusted by hand, thus achieving free adjustment of the lamp head angle. It has a simple structure and strong practicality. Attached Figure Description

[0026] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0027] like Figures 1 to 9The diagram shown is a structural schematic of a lamp with an adjustable lamp head angle provided by this utility model. The lamp with an adjustable lamp head angle includes a lamp holder 10, a lamp body assembly 20 located on the lamp holder 10, a lamp cover assembly 30 connected to and protecting the lamp body assembly 20, and a rotating fastener 40 located between the lamp holder 10 and the lamp body assembly 20. The lamp with an adjustable lamp head angle also includes other functional modules, such as a charging device connected to the lamp, etc., which should be known to those skilled in the art and will not be described in detail here.

[0028] like Figure 3 As shown, the lamp holder 10 includes a lamp holder housing 11 and a cover 12 connected to the lamp holder housing 11.

[0029] like Figure 4 As shown, the lamp holder housing 11 includes a lamp holder body 111, a mounting surface 112 located on the lamp holder body 111, and a first insertion hole 113 opened on the mounting surface 112.

[0030] The lamp holder body 111 is a cylindrical structure with a sealing edge 1111 surrounding it to form a sealed space with the cover 12 to isolate external dust. The lamp holder body 111 also includes an insertion groove 1112 provided on the sealing edge 1111 to facilitate quick positioning of the lamp holder housing 11 on the cover 12.

[0031] like Figure 5 As shown, the mounting surface 112 is used to place the lamp body assembly 20, and it is an inwardly concave hemispherical surface. The cross-section of the mounting surface 112 along the arrangement direction of the lamp holder body 111 and the mounting surface 112 is a semi-circular arc, and the central axis of symmetry of the semi-circular arc intersects with the semi-circular arc to form an intersection point 100 of the axis of symmetry.

[0032] The first insertion hole 113 is used to pass through the rotating fixing member 40. It is a circular through hole, and the first through hole 113 is located on the side of the mounting surface 112 and not on the intersection point 100 of the axis of symmetry. That is, the first through hole 113 is spaced apart from the intersection point 100 of the axis of symmetry. The position of the first insertion hole 113 can also be designed according to actual needs. Specifically, if the first insertion hole 113 is closer to the intersection point 100 of the axis of symmetry, the rotation angle of the lower shell 211 on the mounting surface 112 is smaller. If the first insertion hole 113 is farther away from the intersection point 100 of the axis of symmetry, the rotation angle of the lower shell 211 on the mounting surface 112 is larger.

[0033] like Figure 3As shown, the cover 12 is used to support the lamp holder housing 11, and it can be a circular plate. The cover 12 includes two receiving grooves 121 formed on the cover 12, two fixing components 122 respectively mounted on each receiving groove 121, and a plugging protrusion 123 located on the cover 12. The cover 12 can be fixedly connected to the lamp holder housing 11 by screws.

[0034] Each of the receiving slots 121 is used to accommodate the fixing component 122, which is formed on the side of the plate 11 facing the lamp holder housing 11.

[0035] Each of the fixing components 122 includes a magnetic member 124 mounted on the receiving groove 121, and a fastening cover 125 clamped to the outside of the magnetic member 124.

[0036] The magnetic attachment 124 is used to attach and fix the lamp with adjustable lamp head angle to a magnetic wall or ceiling for easy installation. The magnetic attachment 124 can be a magnet or other magnetic attachment.

[0037] The fastening cover 125 is used to protect and install the magnetic suction member 124, and it covers the outside of the magnetic suction member 124. The fastening cover 125 can be a rectangular cover with a hollow interior and one open side. The fastening cover 125 fastens to the receiving groove 121, and the outer edge of the fastening cover 125 fits precisely into the gap between the magnetic suction member 124 and the receiving groove 121, and is tightly fitted, thereby fixing the magnetic suction member 124 to the cover body 12 to prevent the magnetic suction member 124 from falling off during the movement of the lamp. In addition, the fastening cover 125 is made of metal materials such as iron, which can gather the magnetic lines of force of the magnetic suction member 124, thereby enhancing the overall magnetism of the fixing component 122 and improving its attraction force. The working principle of the fastening cover 125 made of metal gathering the magnetic lines of force of the magnetic suction member 124 is itself existing technology and will not be described in detail here.

[0038] The insertion protrusion 123 is used for the lamp holder housing 11 to be quickly positioned on the cover 12, and its size and shape are adapted to the size and shape of the insertion groove 1112.

[0039] The lamp body assembly 20 includes a lamp housing assembly 21 and a light source assembly 22 located within the lamp housing assembly 21.

[0040] like Figure 7 As shown, the lamp housing assembly 21 includes a lower lamp housing 211 and an upper lamp housing 212 connected to the lower lamp housing 211.

[0041] like Figure 6As shown, the lower lamp housing 211 includes a lamp housing body 2111 and a second insertion hole 2112 formed on the lamp housing body 2111 for the rotating fixing member 40 to pass through. The lower lamp housing 211 may also be provided with a charging port for charging the light source assembly 22 and a fixing component for fixing the light source assembly 22, etc., which should be well known to those skilled in the art.

[0042] The outer surface of the lamp housing body 2111 is a hemispherical surface, and the shape of the outer surface of the lamp housing body 2111 is adapted to the shape of the mounting surface 112. The lamp housing body 2111 is in close contact with the mounting surface 112. The cross-section of the lamp housing body 2111 along the arrangement direction of the lamp holder body 111 and the mounting surface 112 is a semi-circular arc.

[0043] The second socket 2112 is formed on the lower lamp housing 211, and the second socket 2112 is not located at the intersection of the central axis of symmetry of the lamp housing body 2111 and the lamp housing body 2111; that is, the second socket 2112 is also spaced apart from the intersection point. Preferably, the distance of the second socket 2112 from the intersection point is equal to the distance of the first socket 113 from the intersection point 100 of the axis of symmetry, so that the lamp housing body 2111 and the lamp holder housing 11 can completely overlap, achieving the purpose of folding the lamp.

[0044] like Figure 7 As shown, the upper lamp housing 212 is used to support and fix the lamp shade assembly 30, and the upper lamp housing 212 can be a circular cover. The upper lamp housing 212 can be screwed onto the lower lamp housing 211, forming a relatively sealed cavity between the two to house the light source assembly 22.

[0045] like Figure 7 As shown, the light source assembly 22 includes a charging plug 221, a circuit board 222 connected to the charging plug 221, a power supply 223 connected to the circuit board 222, and a light source 224 connected to the power supply.

[0046] The charging plug 221 is used to charge the power supply 223, and the charging plug 221 is fixedly connected to the circuit board 222.

[0047] One side of the circuit board 222 is connected to the charging plug 221, and the other side is connected to the power supply 223. The circuit board 222 also has some electronic components, such as resistors, capacitors, and transistors. The circuit on the circuit board 222 is used not only to convert mains power into power that can charge the power supply 223, but also to enable the power supply 223 to provide suitable power to the light source 224. This is existing technology and will not be described in detail here.

[0048] The power supply 223 is electrically connected to the circuit board 222. The power supply 223 can be a rectangular battery block. One side of the power supply 223 is connected to the circuit board 222, and the other side is connected to the light source 224. During charging, the power supply 223 converts external electrical energy into its stored chemical energy; during discharging, the power supply 223 converts its stored chemical energy into electrical energy for the light source 224. The power supply 223 can also charge and discharge simultaneously; no specific limitation is made to its usage here.

[0049] The light source 224 is electrically connected to the power supply 223 and is used for illumination. It is conceivable that, in order to dissipate heat from the light source 224, a heat sink, made of metal, is also provided on the light source 224.

[0050] like Figure 8 As shown, the lampshade assembly 30 is used to protect the light source assembly 22, and includes a dustproof plate 31 connected to the upper lamp housing 212 and a waterproof cover 32 connected to the dustproof plate 31.

[0051] The dustproof plate 31 is used to prevent external dust from entering the upper lamp housing 212, thereby causing unnecessary impact on the light source assembly 22. It can be fixed to the upper lamp housing 212 by adhesive.

[0052] The waterproof cover 32 is used to prevent external water from entering the upper lamp housing 212, thereby affecting the normal use of the lamp body assembly 20. It can be fixed to the upper lamp housing 212 by adhesive.

[0053] like Figure 9 As shown, the rotating fastener 40 is used to connect and assemble the lamp body assembly 20 and the lamp holder 10. It includes a screw 41 that passes through the first socket 113 and the second socket 2112, a fixing sleeve 42 that is sleeved on the screw 41, and a sealing ring 43 located between the screw 41 and the fixing sleeve 42.

[0054] The screw 41 is used to cooperate with the fixing sleeve 42 to fix the lamp body assembly 20 to the lamp holder 10, and passes through the mounting surface 112 and the lower lamp housing 211. The screw 41 includes an end (not shown), which may be a screw head, which abuts against the lower housing 211 to facilitate fixing the lower housing 211 to the mounting surface 112.

[0055] The fixing sleeve 42 passes through the lower lamp housing 211 and the mounting surface 112 and is fitted over the screw 41. The fixing sleeve 42 and the screw 41 are arranged facing each other and threaded together. The fixing sleeve 42 can be a hollow cylindrical sleeve with one end open, and the outer radius of the cylindrical sleeve is approximately equal to the radius of the first insertion hole 113 and the second insertion hole 2112, so that the screw 41 and the fixing sleeve 42 are tightly fitted and fixed in the first insertion hole 113 and the second insertion hole 2112. The fixing sleeve 42 also includes a stop 421, which is used to abut against the mounting surface 112 to facilitate the fixing of the lower lamp housing 211 onto the mounting surface 112 with the screw 41. The stop 421 can be a ring, and the radius of the ring is larger than the radius of the first insertion hole 113.

[0056] The sealing ring 43 is used to facilitate the adjustment of the lamp body assembly's position on the lamp holder 10. It is a ring made of elastic material such as plastic. Specifically, because the sealing ring 43 is made of elastic material, it has elasticity, allowing for movement between the lower housing 211 and the mounting surface 112, enabling the lower housing 211 to be adjusted on the mounting surface 112 according to later needs. Furthermore, the sealing ring 43 can also fill the gap between the screw 41 and the fixing sleeve 42. Located between the screw 41 and the fixing sleeve 42, the sealing ring 43 fills the unavoidable gaps that exist during the connection and assembly, preventing external water or dust from entering the lower lamp housing 211 and affecting the light source assembly 22.

[0057] like Figure 8As shown, during assembly, simply screw the screw 41 into the fixing sleeve 42. When the end of the screw 41 abuts against the lower housing 211, and the top 421 of the fixing sleeve 42 abuts against the mounting surface 112, and since the screw 41 and the fixing sleeve 42 are positioned opposite each other, the lower housing 211 and the mounting surface 112 abut against each other and are fixed, thus fixing the lamp body assembly 20 onto the lamp holder 10. When it is necessary to adjust the illumination position of the light source assembly 22 according to actual needs, simply move the lower lamp housing 211 by hand. The lower lamp housing 211 can then rotate around the central axis of the screw 41 and the fixing sleeve 42. During this rotation, the sealing ring 43 will undergo elastic deformation to absorb the displacement of the lower lamp housing 211. At this time, the screw 41 and the fixing sleeve 42 still connect and fix the lower lamp housing 211 to the mounting surface 112, so that after the rotation is completed, the lower lamp housing 211 remains tightly connected and fixed to the mounting surface 112. When the central axis of the lamp housing assembly 20 does not coincide with the central axis of the lamp holder 10, the light emission direction of the lamp housing assembly 20 will not coincide with its central axis. Then, the angle between the light emission direction and its central axis can be adjusted according to actual needs, thereby achieving the purpose of adjusting the light emission direction.

[0058] Compared with the prior art, the lamp with adjustable lamp head angle provided by this utility model fixes the lamp body assembly 20 to the lamp holder 10 through the rotating fixing member 40. The rotating fixing member 40 includes a screw 41 passing through the first insertion hole 113 and the second insertion hole 2112, a fixing sleeve 42 sleeved on the screw 41, and a sealing ring 43 made of elastic material such as plastic located between the screw 41 and the fixing sleeve 42. The screw 41 and the fixing sleeve 42 are arranged opposite to each other to fix the lower lamp housing 211 on the mounting surface 112, and the lower lamp housing 211 can be moved according to the user's actual needs, so that the sealing ring 43 elastically deforms, and the lower lamp housing 211 rotates around the central axis of the screw 41 and the fixing sleeve 42 to adjust the illumination position of the light source assembly 22. This utility model can fix the lower lamp housing 211 to the mounting surface 112 using only the screw 41, the fixing sleeve 42 and the sealing ring 43. The position of the lower lamp housing 211 on the mounting surface 112 can be adjusted by manually moving the lower lamp housing 211, thereby realizing the free adjustment of the lamp head angle. It has a simple structure and is highly practical.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
