Description

Technical Field

[0001] The invention relates to the technical field of lighting fixtures, and in particular to a ceiling lamp with a night light. Background Art

[0002] Ceiling lamps are a type of lamp. As the name implies, they are called ceiling lamps because the back of the lamp is relatively flat and the back of the lamp is completely attached to the roof during installation. The light sources of ceiling lamps include ordinary white bulbs, fluorescent lamps, high-intensity gas discharge lamps, halogen tungsten lamps, LEDs, etc. In order to broaden the functions of ceiling lamps, many manufacturers have designed ceiling lamps with backlights or night lights. Ceiling lamps with night lights are also widely used in family homes, hotels, hospitals, nursing homes and other places. For example, in a room, getting up at night to turn on and off the lights may disturb others, while ceiling lamps with night lights can provide soft light, which is convenient for people to move at night without affecting the rest of others.

[0003] For example, the Chinese utility model patent publication number CN211694580U discloses a light guide plate type ceiling lamp with a backlight source, including a ceiling plate with a receiving hole at the lower end, a coupling connection terminal and a driver installed in the receiving hole, a base plate with a convex ring at the upper end, a countersunk hole provided at the lower end of the base plate, a middle hole with two ends connected to the countersunk hole and the inner hole of the convex ring in a one-to-one correspondence, a backlight source provided at the outer periphery of the convex ring, a light-transmitting ring covering the backlight source and detachably connected to the base plate, a reflective paper bonded to the upper end of the countersunk hole, a main light source provided at the side periphery of the countersunk hole, a light guide plate and a diffuser plate located at the lower side of the main light source and bonded to the side periphery of the countersunk hole respectively, a light-transmitting cover covering the diffuser plate and detachably connected to the base plate, and a ceiling plate located in the inner hole of the convex ring and detachably connected to the base plate. The shape of the light-transmitting ring is a cone with a small end located at the upper end. The backlight source is an annular RGB light source bonded to the outer periphery of the convex ring. The LED lamp beads of the annular RGB light source are located on the outer periphery of the annular RGB light source. The LED lamp beads of the annular RGB light source include a plurality of red LED lamp beads, a plurality of green LED lamp beads, and a plurality of blue LED lamp beads evenly spaced along the circumference of the annular RGB light source.

[0004] This backlight ceiling lamp also has the following problems: the light-transmitting ring is detachably connected to the convex ring of the base, and the light-transmitting cover is detachably connected to the lower position of the base. When viewed from the side, the ceiling lamp is divided into an upper and lower part. At the same time, the light-transmitting cover covers the diffusion plate connected to the base. When viewed from the front, the ceiling lamp is divided into an inner and outer part by the inner edge of the light-transmitting cover. The appearance of the entire ceiling lamp is divided, and the appearance is not simple enough; the LED lamp beads on the backlight source are installed on the outer side of the convex ring. In order to make the light emitted by the LED lamp beads more uniform and prevent the generation of light spots, the spacing between adjacent LED lamp beads is small when the lamp beads are arranged, which will result in a large number of lamp beads and increase costs; the light emitted by the backlight source must first pass through the air before it can be irradiated on the light-transmitting ring, resulting in large light losses. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a ceiling lamp with a night light which has a simple appearance, saves lamp beads and has low light loss in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a ceiling lamp with a night light, comprising a lamp housing, the lamp housing having a cavity opening downward, and a main light emitting component is arranged in the cavity; a night light lens is arranged above the lamp housing, and a night light installation mechanism is arranged near the center of the night light lens; a night light light source is arranged at the night light installation mechanism, and the light emitted by the night light light source horizontally penetrates the night light lens and is emitted from the outer side wall of the night light lens; a lampshade is arranged below the lamp housing, and the lampshade comprises a bottom plate and a second annular wall extending upward from the circumference of the bottom plate, and the second annular wall is sleeved on the outer side wall of the night light lens.

[0007] In order to ensure the uniformity of the light emitted from the outer wall of the night light lens even when fewer lamp beads are set, the night light installation mechanism includes a mounting groove arranged in a ring with the center of the night light lens as the center and opening downward, the distance between the mounting groove and the center of the night light lens is N1, the distance between the outer wall of the night light lens and the center of the night light lens is N2, and N1 / N2 is 1 / 3 to 1 / 2. The above scheme increases the path length of the night light light source transmitted in the night light lens. Since the night light source is usually an LED lamp bead, its light-emitting angle is generally around 120 degrees. Therefore, the longer the path of the light emitted by the lamp bead along the radial transmission of the ceiling lamp, the longer the arc length of the outer wall covered when the light emitted by the lamp bead is transmitted to the outer wall of the night light lens, and the larger the central angle of the night light lens corresponding to the arc length, thereby reducing the number of lamp beads.

[0008] Preferably, the position of the night light lens corresponding to the mounting groove is provided with a convex ring extending upward, and the convex ring is provided with a clamping seam connected to the mounting groove, and the night light source is inserted into the clamping seam. With the above solution, the convex ring increases the thickness of the night light lens at the mounting groove, and compensates for the loss of structural strength caused by the opening of the mounting groove; at the same time, the clamping seam provided in the convex ring allows the night light source to be directly inserted into it, avoiding the use of traditional bonding methods to fix the night light source, and reducing the difficulty of assembly.

[0009] Preferably, the upper edge of the outer side wall of the night light lens is provided with a flange extending radially outward and obliquely upward along the night light lens; the inner side wall of the second ring wall is provided with a slot, and the flange is snapped into the slot. The above solution simplifies the structure and assembly difficulty of the ceiling lamp.

[0010] Preferably, a convex ring is provided at the upper end of the lamp housing, and at least two first connection holes are provided on the side wall of the convex ring; a clearance hole is provided at the center of the night light lens, which penetrates from top to bottom and allows the convex ring to pass through, and the hole wall of the clearance hole extends radially inward along the night light lens to have a connection block that can be plugged into the first connection hole. The above scheme is adopted to realize the connection between the lamp housing and the night light lens, and this connection method does not require the aid of other structures, and is convenient and fast when connected; the connection position of the first connection hole and the connection block is located in the clearance hole, and the first connection hole and the connection block are both far away from the transmission path of the light source of the night light, so the connection method in this embodiment will not affect the light transmission of the night light source.

[0011] Preferably, the outer periphery of the convex ring of the lamp housing is concave downward to form a concave cavity; the inner groove wall of the installation groove has a retaining rib extending downward, the retaining rib is located in the concave cavity, and the night light source is attached to the inner groove wall of the installation groove and the retaining rib. The concave cavity is used to provide a space for installing the night light source, and is conducive to the deformation of the lamp housing so as to insert the connecting block into the first connecting hole.

[0012] Preferably, the connection block is provided with a first vertically arranged screw hole, the lamp housing is provided with a first connecting hole, and a screw passes through the first connecting hole and is connected to the first screw hole to connect the night light lens to the lamp housing. The above solution can increase the firmness of the connection between the night light lens and the lamp housing.

[0013] Preferably, the ceiling lamp with night light also includes a mounting plate arranged above the lamp housing for connecting to the ceiling, and a plurality of first connecting plates are arranged at intervals on the outer periphery of the mounting plate, and the first connecting plates extend downward from the outer periphery of the mounting plate first, and then extend radially outward along the mounting plate; the wall of the yield hole extends radially inward along the night light lens to have second connecting plates corresponding to the same number of the first connecting plates, and the first connecting plates are partially accommodated in the concave cavity 12a below the second connecting plates. The above scheme simplifies the connection between the mounting plate and the night light lens.

[0014] Preferably, the ceiling lamp with night light further comprises a light shielding sheet, which is located above the night light lens and is used to block light from being emitted from the upper surface of the night light lens. By adopting the above solution, light loss is reduced.

[0015] Preferably, the ceiling lamp with night light also includes a light shielding ring, which includes a first ring portion arranged horizontally and a second ring portion extending downward from the outer edge of the first ring portion, the first ring portion is located above the night light lens, and the second ring portion is located on the outer side wall of the second ring wall to block light from being emitted from the outer side wall of the second ring wall. With the above solution, the light shielding ring blocks the light emitted from the outer side wall of the second ring wall of the lampshade, allowing the light to pass through the lampshade to the front, forming an effect in which the light in the outer circle is brighter and gradually darkens in the middle, and the light effect is beautiful.

[0016] Compared with the prior art, the advantages of the present invention are: the night light lens is arranged above the lamp shell, the lampshade is directly mounted on the outer side wall of the night light lens, and the lampshade completely wraps the lamp shell and the night light lens inside the lampshade, so that the appearance of the ceiling lamp with night light is more concise; the light emitted by the night light light source passes through the night light lens horizontally, and since the light conduction effect of the night light lens is better than that of the air, the loss in the light transmission process is small, so the number of lamp beads can be reduced.

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 7The preferred embodiment of the ceiling lamp with night light of the present invention is shown, which comprises a lamp housing 1, a main light emitting assembly, a night light lens 3, a night light source 4, a lampshade 5, a mounting plate 6, a shading sheet 7, a shading ring 8 and a power supply board 9. The main light emitting assembly is arranged inside the lamp housing 1, and the night light lens 3 and the night light source 4 are arranged on the back of the lamp housing 1.

[0026] like Figures 2 to 4 As shown in Figures 6 and 7, the lamp housing 1 includes a housing top 101 and a first annular wall 102 extending downward from the outer edge of the housing top 101, and the housing top 101 and the first annular wall 102 together enclose a cavity 1a with a downward opening; a main light emitting assembly is provided in the cavity 1a, and the main light emitting assembly includes a main light source 21 arranged on the inner side of the first annular wall 102, a light guide plate 23 arranged horizontally in the cavity 1a and corresponding to the position of the main light source 21, and a reflective paper 22 arranged above the light guide plate 23; the light emitted by the main light source 21 passes through the light guide plate 23 and is emitted downward.

[0027] like Figures 2 to 4 As shown, the center of the shell top 101 is upwardly protruding to form a convex ring 11, and the outer periphery of the convex ring 11 is concave downward to form a concave cavity 12a, and at least two first connection holes 100 are provided on the side wall of the convex ring 11. The night light lens 3 is annular and is horizontally arranged above the lamp housing 1; a clearance hole 34 is provided at the center of the night light lens 3, which passes through the convex ring 11 of the lamp housing 1, and the hole wall of the clearance hole 34 extends radially inward along the night light lens 3 to form a connecting block 341 that can be plugged into the first connecting hole 100. Align the connecting block 341 with the first connecting hole 100, and forcefully squeeze the connecting block 341 on the night light lens 3 into the first connecting hole 100 to achieve the connection between the lamp housing 1 and the night light lens 3. This connection method does not require the use of other structures, and the connection is convenient and quick. In this embodiment, the presence of the convex ring 11 and the concave cavity 12a makes it easy for the shell top 101 to deform and thus facilitates the insertion of the connecting block 341 into the first connecting hole 100.

[0028] like Figures 4 to 7 As shown, the lower surface of the night light lens 3 is provided with a mounting groove 31 with an opening downward, and the mounting groove 31 is arranged in a ring shape with the center of the night light lens 3 as the center of the circle, and the night light light source 4 is arranged in the mounting groove 31; the distance between the mounting groove 31 and the center of the night light lens 3 is N1, and the distance between the outer wall of the night light lens 3 and the center of the night light lens 3 is N2, and N1 / N2 is 1 / 3 to 1 / 2. The above scheme increases the path length of the night light light source transmitted in the night light lens 3. Since the night light source is usually an LED lamp bead, its light emitting angle is generally about 120 degrees. Therefore, the longer the path of the light emitted by the lamp bead along the radial transmission of the ceiling lamp is, the longer the arc length of the outer wall covered when the light emitted by the lamp bead is transmitted to the outer wall of the night light lens 3, and the larger the central angle of the night light lens 3 corresponding to the arc length, so that the number of lamp beads can be reduced.

[0029] The position of the night light lens 3 corresponding to the mounting groove 31 is provided with a convex ring 32 extending upward, and a snap joint 321 communicating with the mounting groove 31 is provided on the convex ring 32; the night light source 4 includes a light strip 41 and lamp beads 42 arranged on the outer wall of the light strip 41, the light strip 41 is accommodated in the mounting groove 31, and the upper end of the light strip 41 is snapped into the snap joint 321, and the lamp beads 42 are just facing the night light lens 3, so that the light emitted by the lamp beads 42 directly enters the night light lens 3 horizontally. In the above scheme, the convex ring 32 increases the thickness of the night light lens 3 at the mounting groove 31, and compensates for the loss of structural strength caused by the opening of the mounting groove 31; at the same time, the snap joint 321 provided in the convex ring 32 allows the night light source 4 to be directly plugged into it, avoiding the use of traditional bonding to fix the night light source 4, and reducing the difficulty of assembly.

[0030] A retaining rib 342 extends downward from the inner groove wall of the installation groove 31 . The retaining rib 342 is located in the concave cavity 12 a . The light strip 41 is attached to the inner groove wall of the installation groove 31 and the retaining rib 342 .

[0031] The lampshade 5 is arranged below the lamp housing 1, and includes a bottom plate 51 and a second annular wall 52 extending upward from the circumference of the bottom plate 51, and the second annular wall 52 is sleeved on the outer wall of the night light lens 3. In order to simplify the structure and assembly difficulty of the ceiling lamp, in this embodiment, the upper edge of the outer wall of the night light lens 3 is provided with a flange 33 extending upward and obliquely outward along the radial direction of the night light lens 3; the inner wall of the second annular wall 52 is provided with a slot 521, and the flange 33 is snapped into the slot 521. The light emitted by the night light source 4 passes through the night light lens 3 horizontally and is emitted from the outer wall of the night light lens 3, and then is emitted from the second annular wall 52.

[0032] The ceiling lamp with night light also includes a mounting plate 6 arranged above the lamp housing 1 for connecting with the ceiling. A plurality of first connecting plates 61 are arranged at intervals on the outer periphery of the mounting plate 6. The first connecting plates 61 extend downward from the outer periphery of the mounting plate 6 first, and then extend radially outward along the mounting plate 6. The wall of the hole 34 of the clearance hole 34 extends radially inward along the night light lens 3 to have second connecting plates 344 with the same number and positions as the first connecting plates 61. The first connecting plates 61 are partially accommodated in the concave cavity 12a below the second connecting plates 344. The mounting plate is arranged in the clearance hole 34, which reduces the thickness of the ceiling lamp with night light. At the same time, the second connecting plate 344 arranged on the clearance hole 34 simplifies the connection method between the mounting plate 6 and the night light lens 3. The second connecting plate 344 and the connecting block 341 both extend radially inward from the wall of the clearance hole 34, and the second connecting plate 344 is connected to the connecting block 341.

[0033] The connection block 341 in this embodiment is hollow inside to form a mounting cavity 341a, and a vertically arranged first screw hole 343 is provided in the mounting cavity 341a. A first connecting hole 100 is provided on the lamp housing 1, and a screw passes through the first connecting hole 100 and is connected to the first screw hole 343, thereby connecting the night light lens 3 to the lamp housing 1. The above scheme can increase the firmness of the connection between the night light lens 3 and the lamp housing 1. A vertically arranged second screw hole 345 is also provided in the mounting cavity 341a, and a second connecting hole 91 is provided on the power board 9. A screw passes through the second connecting hole 91 and is connected to the second screw hole 345, thereby connecting the night light lens 3 to the power board 9.

[0034] The ceiling lamp with night light also includes a shading sheet 7 and a shading ring 8. The shading sheet 7 is located above the night light lens 3 and is used to block light from being emitted from the upper surface of the night light lens 3. The above scheme is adopted to reduce light loss. The shading ring 8 includes a first ring portion 81 arranged horizontally and a second ring portion 82 extending downward from the outer edge of the first ring portion 81. The first ring portion 81 is located above the night light lens 3, and the second ring portion 82 is located on the outer side wall of the second ring wall 52 and is used to block light from being emitted from the outer side wall of the second ring wall 52. With the above scheme, the shading ring 8 blocks the light emitted from the outer side wall of the second ring wall 52 of the lampshade, so that the light passes through the lampshade to the front, forming an effect in which the light in the outer circle is brighter and gradually darkens in the middle, and the lighting effect is beautiful.

[0035] In this embodiment, the assembly process of the ceiling lamp with night light is as follows: place the mounting plate 6 above the lamp housing 1, place the first connecting plate 61 on the mounting plate 6 in the concave cavity 12a and make the first connecting plate 61 away from the first connecting hole 100 on the convex ring 11, insert the night light source 4 into the mounting groove 31 on the night light lens 3, and then place the night light lens 3 above the lamp housing 1, and forcefully snap the connecting block 341 into the first connecting hole 100 to complete the connection between the mounting plate 6, the lamp housing 1 and the night light lens 3; perform screw connections as needed, and then install the main light emitting assembly. The main light emitting assembly belongs to the prior art and will not be described in detail; snap the lampshade 5 into the flange 33 on the night light lens 3 to complete the assembly.
