Description
Technical Field
[0001] The utility model relates to the technical field of lamps, in particular to a ceiling lamp and a lighting system provided with the ceiling lamp. Background Art
[0002] At present, in order to solve the problem of facial shadows caused by the light projected by the LED light source to the lampshade being blocked by the internal shielding of the lamp, there are usually three solutions for the surface-emitting lamps (such as ceiling lamps and panel lamps) on the market:
[0003] The first one is to raise the lampshade of the lamp, which is a commonly used solution. However, raising the lampshade will make the lamp look heavy, which will not only affect the overall appearance of the product, but also increase the packaging and transportation costs.
[0004] The second method is to increase the haze of the lampshade. This solution has a low implementation cost and although it can improve the uniform illumination effect of the LED light source to a certain extent, it will cause a significant decrease in the light parameter performance of the lamp.
[0005] The third method is to reduce the height of the outer shell of the internal covering of the lamp (such as the outer shell of the power supply). However, this solution requires that the driving power module of the power supply adopts smaller components to reduce the overall height of the driving power module, thereby indirectly reducing the height of the outer shell, resulting in a significant increase in the production cost of the power supply. Summary of the invention
[0006] In order to solve the above problems, the main purpose of the utility model is to provide a ceiling lamp which can make the light spot on the face even and bright, has excellent light parameter performance and low production cost.

[0009] As can be seen from the above, by setting the lifting step, the lifting step can raise the light-emitting surface of the LED light source (that is, make the lamp beads of the LED light source closer to the face of the lampshade), so as to indirectly reduce the shielding height of the power supply, thereby reducing the shielding range of the light emitted by the LED light source by the power supply; in addition, with the design of the sunken recessed position of the sunken step portion in the middle of the lifting step, the spatial structure of the chassis can be more fully utilized to further reduce the shielding range of the light by the power supply while keeping the height of the power supply unchanged; furthermore, since the luminous intensity of the LED light source is mostly concentrated within a 90° cone angle, a chamfered surface is provided on the outer shell of the power supply to realize a light-shielding design on the edge side of the outer shell near the LED light source, thereby solving the problem of shielding the light emitted by the LED light source when the edge side of the outer shell near the LED light source is at a right angle, thereby preventing shadows from being generated on the face of the lampshade and improving the lighting effect of the ceiling lamp.

[0012] A further solution is that the angle between the chamfered surface and the height direction of the chassis is between 30° and 80°.
[0013] It can be seen from the above that, when the internal space structure of the housing allows, better light shielding can be achieved by increasing the inclination angle of the chamfered surface, so as to minimize the shielding range of the power supply on the light emitted by the LED light source.

[0038] Ceiling lamp embodiment
[0039] Combination Figure 1 and Figure 2 The ceiling lamp 100 includes a chassis 1, an LED light source 2, a light source cover 3, a connection terminal 4, a power supply 5 and a lampshade 6.
[0040] Combination Figures 3 to 6 The chassis 1 has a receiving position 11, and a raised step 12 is formed at the bottom of the receiving position 11 protruding toward the opening of the receiving position 11, and a sunken step portion 121 is formed in the middle of the raised step 12. The sunken step portion 121 is recessed at the top of the raised step 12 away from the opening of the receiving position 11, and a sunken recess 1211 is formed at the bottom of the sunken step portion 121 away from the opening. The raised step 12 can serve as a reinforcing rib structure to ensure that the overall structural strength of the chassis 1 meets the use requirements, and to simplify the structure of the chassis 1 to the maximum extent, so that the wall thickness of the chassis 1 is as small as possible, so as to facilitate the lightweight design of the ceiling lamp 100, save the material usage of the chassis 1, and reduce the production cost.
[0041] Preferably, in the height direction of the chassis 1, the first bottom surface of the sunken recess 1211 is flush with the second bottom surface of the chassis 1, so that the chassis 1 after installation can better fit the wall, and better avoid deformation of the chassis 1 during installation. At the same time, the strength of the chassis 1 after installation is also guaranteed, and the chassis 1 is prevented from being deformed due to the squeezing force during the connection between the ceiling lamp 100 and the external power supply cable. Of course, as another optional solution, in other embodiments, the first bottom surface of the sunken recess 1211 can also be located between the top surface of the raised step 12 and the second bottom surface of the chassis 1.
[0042] A connection slot 111 is provided at the bottom of the accommodation position 11, and the connection slot 111 passes through the bottom wall of the chassis 1. Preferably, the connection slot 111 is located between the side wall of the chassis 1 and the raised step 12. Of course, as another optional solution, the connection slot 111 can also be provided at the bottom of the sinking step 121. The connection slot 111 can be used for conventional connection when the chassis 1 is installed, so that the chassis 1 can be fixed to the wall through a second locking member (such as a bolt).
[0043] Preferably, as in the present embodiment, since the connection slot 111 is located between the side wall of the chassis 1 and the raised step 12, in order to facilitate the construction personnel to fix the chassis 1 at a single point when installing the chassis 1 and prevent the chassis 1 from being deformed when the construction personnel drill holes by themselves, a reserved hole 1212 is provided at the bottom of the sinking step 121, and the reserved hole 1212 is preferably a blind hole. The reserved hole 1212 is set as a blind hole, so that when the construction personnel do not use the reserved hole 1212, external dust will not enter the chassis 1 through the reserved hole 1212, effectively preventing external dust from contaminating the LED light source 2 and the lampshade 6, etc., thereby ensuring the lighting effect of the ceiling lamp 100.
[0044] The reserved hole 1212 is formed by protruding from the bottom of the sinking step portion 121 to the opening of the accommodation position 11; preferably, the reserved hole 1212 includes a countersunk portion 12121 and a guide portion 12122, and the countersunk portion 12121 is located between the sinking step portion 121 and the guide portion 12122, that is, the guide portion 12122 protrudes from the bottom of the countersunk portion 12121 to the opening of the accommodation position 11. The guide portion 12122 is preferably in an inverted cone shape; in addition, in the height direction of the chassis 1, the bottom end of the guide portion 12122 is preferably flush with the second bottom surface of the chassis 1, and the height H of the guide portion 12122 is preferably between 0.3 mm and 1 mm. This design can ensure that the chassis 1 fits the wall after installation, and effectively prevents the sinking step portion 121 and / or the countersunk portion 12121 from being deformed after the reserved hole 1212 is pierced by the pointed tail self-tapping screw. Among them, as another optional scheme, in other embodiments, in the height direction of the chassis 1, the third bottom surface of the countersunk portion 12121 is flush with the second bottom surface of the chassis 1, and the height H of the guide portion 12122 is preferably also between 0.3 mm and 1 mm.
[0045] Through the structural design and position design of the reserved holes 1212, the reserved holes 1212 on the chassis 1 can guide the construction workers to drill holes on the chassis 1 regularly, thereby avoiding deformation of the chassis 1 after drilling, protecting the chassis 1, and ensuring the heat dissipation of the LED light source 2, thereby avoiding the ceiling lamp 100 from freezing. When the construction workers install the chassis 1, they can choose to use the connecting slot hole 111 for conventional installation, or use the reserved hole 1212 to fix the chassis 1 at a single point first; when the construction workers choose to use the reserved hole 1212, the construction workers can apply pressure to the reserved hole 1212 by controlling the pointed tail self-tapping screw, so that the pointed tail self-tapping screw pierces the reserved hole 1212 and is fixedly connected to the wall, thereby completing the fixed connection between the chassis 1 and the wall; in addition, since the reserved hole 1212 is set to an inverted cone shape, during the process of the pointed tail self-tapping screw applying pressure and piercing the reserved hole 1212, the inverted cone-shaped reserved hole 1212 can guide the pointed tail self-tapping screw, so that the pointed tail self-tapping screw can better pierce the reserved hole 1212 and be fixedly connected to the wall, thereby preventing the chassis 1 from being deformed under the pressure of the pointed tail self-tapping screw.
[0046] The LED light source 2 is installed on the top of the raised step 12; preferably, the raised step 12 includes a first step portion 122 and a second step portion 123, the second step portion 123 is connected between the bottom of the accommodating position 11 and the first step portion 122, and the width of the second step portion 123 is greater than the width of the first step portion 122. This design is conducive to increasing the structural strength of the raised step 12, so that the raised step 12 can better carry the power supply 5 installed in the sunken recess 1211.
[0047] Furthermore, a positioning bone position 1221 and a first connection hole 1222 are formed on the top of the first step portion 122, and the LED light source 2 has a positioning slot 21 and a second connection hole 22. The positioning bone position 1221 is preferably truncated, and the first connection hole 1222 preferably passes through the first step portion 122; the positioning bone position 1221 is used to engage with the positioning slot 21 to position and limit the installation of the LED light source 2, and also enables the first connection hole 1222 to match and communicate with the second connection hole 22 (even if the first connection hole 1222 can be coaxially arranged with the second connection hole 22), so that when the LED light source 2 is assembled with the chassis 1, the first locking member 23 (such as a bolt) can quickly pass through the second connection hole 22 and then be fixedly connected with the first connection hole 1222, thereby fixing the LED light source 2 on the chassis 1. In addition, the design of the positioning bone position 1221 and the positioning slot 21 also enables the visual system of the automated assembly equipment to better perform visual positioning with the help of the positioning bone position 1221 when the automated assembly equipment performs automated assembly of the ceiling lamp 100, so as to place the LED light source 2 in the correct position and accurately align the second connecting hole 22 on the LED light source 2 with the first connecting hole 1222 on the first step portion 122, thereby helping to improve assembly efficiency.
[0048] It should be noted that the shape of the raised step 12 and the shape of the sunken step 121 can be changed according to design requirements (such as the position layout of the LED light source 2, the structure of the LED light source 2, the lighting effect of the LED light source 2, etc.). Correspondingly, the number of bone protrusions and the first connecting holes 1222 are also changed and adjusted accordingly according to the shape of the raised step 12. For example, in the height direction of the chassis 1, the outer contour projection of the raised step 12 and the outer contour projection of the sunken step portion 121 are both polygonal, and bone protrusions are preferably provided on both sides of each corner of the polygon, and the bone protrusions are located on the edge of the polygon, and the first connecting hole 1222 is located between two bone protrusions on the same side, and the number of the first connecting holes 1222 is preferably more than two; as in the present embodiment, the LED light source 2 is a roughly linear structure, and the number of the LED light sources 2 is three, and in the height direction of the chassis 1, the outer contour projection of the raised step 12 and the outer contour projection of the sunken step portion 121 are both triangular, and the three LED light sources 2 correspond one-to-one to the three sides of the above-mentioned triangle, so that an LED light source 2 is installed on one side of the triangle, and bone protrusions are provided on both sides of each corner of the triangle, and the number of the first connecting holes 1222 on the same side is preferably two. As another optional scheme, in other embodiments, in the height direction of the chassis 1, the outer contour projection of the raised step 12 and the outer contour projection of the sunken step 121 are both circular, and the number of bone position protrusions and first connecting holes 1222 are preferably more than two, and more than two bone position protrusions and more than two first connecting holes 1222 are distributed around a circle.
[0049] Combination Figure 7 The number of the light source protection covers 3 is equal to the number of the LED light sources 2 . The setting of the light source protection covers 3 can protect the LED light sources 2 and fix the LED light sources 2 in cooperation with the raising steps 12 . Among them, the light source cover 3 has a lamp bead avoidance groove 31, a third connecting hole 33 and a bone position avoidance groove. When the light source cover 3 is covered on the LED light source 2, the lamp beads of the LED light source 2 are located in the lamp bead avoidance groove 31 to prevent the light source cover 3 from blocking the light emitted by the LED light source 2; and the third connecting hole 33 and the second connecting hole 22 on the LED light source 2 are coaxially arranged, so that the first locking piece 23 can pass through the third connecting hole 33 and the second connecting hole 22 in sequence and then be fixedly connected with the first connecting hole 1222 on the lifting step 12, thereby preventing the first locking piece 23 from being directly pressed on the LED light source 2, preventing the first locking piece 23 from being mistakenly electrically connected to the LED light source 2, and preventing the first locking piece 23 from crushing or damaging the LED light source 2; the bone position avoidance groove is covered on the positioning bone position 1221 of the lifting step 12, and avoids the positioning bone position 1221 so that the light source cover 3 and the lifting step 12 can be firmly connected, and the structural design of the light source cover 3 is more reasonable.
[0050] Combination Figure 8 The power supply 5 includes a housing 51 and a driving power module 52. The housing 51 includes a box body 511 and a cover body 512. The box body 511 has a receiving cavity. The cover body 512 is detachably mounted on the box body 511 and covers the opening of the receiving cavity. The driving power module 52 is installed in the receiving cavity so that the housing 51 can protect the driving power module 52.
[0051] A portion of the outer shell 51 is arranged in the sunken recess 1211 of the chassis 1. Through the structural design of the lifting step 12 and the installation position design of the LED light source 2 and the power supply 5, the lifting step 12 can lift the light-emitting surface of the LED light source 2 (that is, make the lamp beads of the LED light source 2 closer to the face of the lampshade 6) to indirectly reduce the shielding height of the power supply 5, thereby reducing the shielding range of the power supply 5 to the light emitted by the LED light source 2; and, in conjunction with the sunken recess 1211 of the sunken step portion 121 in the middle of the lifting step 12, the spatial structure of the chassis 1 can be more fully utilized, so that when the height of the power supply 5 remains unchanged, the shielding range of the power supply 5 to the light can be further reduced.
[0052] In addition, an oblique chamfered surface 5111 is formed between the top wall of the housing 51 and the first side wall of the housing 51 near the LED light source 2, and a rounded surface 5112 is formed between the top wall of the housing 51 and the second side wall of the housing 51 away from the LED light source 2; wherein the second side wall is adjacent to the first side wall and the top wall respectively. In this embodiment, the housing 51 is preferably a rectangular structure; and an oblique chamfered surface 5111 is formed between the top wall of the box body 511 and the first side wall of the box body 511 near the LED light source 2, and a rounded surface 5112 is formed between the top wall of the box body 511 and the second side wall of the box body 511 away from the LED light source 2.
[0053] Since the luminous intensity of the LED light source 2 is mostly concentrated within a 90° cone angle, an oblique chamfered surface 5111 is provided on the outer shell 51 of the power supply 5 to realize a light-shielding design for the edge side of the outer shell 51 near the LED light source 2, thereby solving the problem of blocking the light emitted by the LED light source 2 when the edge side of the outer shell 51 near the LED light source 2 is a right angle, thereby preventing shadows from being generated on the surface of the lampshade 6 and improving the lighting effect of the ceiling lamp 100; and the setting of the chamfered surface 5112 realizes a light-shielding design for the edge side of the outer shell 51 away from the LED light source 2, thereby further preventing the outer shell 51 from blocking the light emitted by the LED light source 2.
[0054] Preferably, the angle a between the chamfered surface 5111 of the housing 51 and the height direction of the chassis 1 is between 30° and 80°. It should be noted that, when the internal space conditions of the housing 51 allow (i.e., the internal space of the housing 51 is sufficient to accommodate the driving power module 52), the angle a between the chamfered surface and the height direction of the chassis 1 is as large as possible (i.e., the angle a is greater than or equal to 45°) to achieve better light protection, so as to minimize the shielding range of the power supply 5 on the light emitted by the LED light source 2.
[0055] Furthermore, in this embodiment, the chassis 1 is preferably made of aluminum alloy or iron by a stamping process, and the overall wall thickness of the chassis 1 is preferably between 0.2 mm and 1 mm; preferably, the overall wall thickness of the chassis 1 can be 0.25 mm. The chassis 1 made of aluminum alloy or iron by a stamping process has high structural strength and thin wall thickness, which is conducive to the lightweight design of the chassis 1 and the ceiling lamp 100, and is also conducive to the heat dissipation of the LED light source 2.
[0056] Furthermore, a grounding spring 1213 may be provided in the sinking step 121, for example, the grounding spring 1213 is bent and extended from the bottom of the sinking step 121 to the open opening of the accommodation position 11; the grounding spring 1213 cooperates with the material of the chassis 1 (such as aluminum alloy or iron) so that the grounding spring 1213 can be used as the grounding end of the ceiling lamp 100, so that the grounding spring 1213 can be electrically connected to the wiring terminal 4 provided in the sinking step 121 to achieve the grounding of the ceiling lamp 100, thereby improving the safety of the use of the ceiling lamp 100. Among them, the wiring terminal 4 is also electrically connected to the LED light source 2 and the driving power module 52 respectively; the setting of the wiring terminal 4 enables a stable and reliable electrical connection between the grounding spring 1213, the LED light source 2, and the driving power module 52, while ensuring the safety of use after wiring.
[0057] Furthermore, the bottom of the sunken step 121 is preferably provided with a threading hole 1214, which passes through the chassis 1; a wire sleeve is embedded in the threading hole 1214. The threading hole 1214 is used for routing the external power supply cable, thereby realizing the concealed routing of the external power supply cable, avoiding the external power supply cable from being exposed outside the ceiling lamp 100, protecting the external power supply cable and improving the aesthetics of the ceiling lamp 100; the wire sleeve is used to further protect the external power supply cable to prevent the external power supply cable from being cut by the edge of the threading hole 1214.
