Description

Technical Field

[0001] The utility model relates to the field of lighting, and particularly to a ceiling lamp. Background Art

[0002] With the improvement of people's living standards, the requirements for home decoration are also constantly increasing. Lamps are an essential part of home decoration. Therefore, various types of lamps have been classified according to usage scenarios or design styles. The ceiling lamp is one of them. The main way to install a ceiling lamp is to have a hanging piece on the bottom surface of the ceiling lamp, and the hanging piece is fixedly installed on the ceiling. After the hanging piece is fixed to the ceiling, the lamp body of the ceiling lamp is fixed to the hanging piece, and then the installation of the ceiling lamp is completed. Most of the existing ceiling lamps only have the function of simple daily lighting, or add the function of light effect on the basis of simple daily lighting. It still cannot meet the needs of people for the usage scenarios of ceiling lamps in life. Adding a night light or background light effect to the ceiling lamp can increase various usage scenarios of the ceiling lamp and bring more convenience to people's lives.

[0003] For example, the Chinese utility model patent publication No. CN220930904U discloses a ceiling lamp including a chassis, a lampshade, a main light source assembly and a backlight assembly. The lampshade is arranged at the bottom of the chassis and forms a main cavity and an annular cavity with the chassis. The main cavity surrounds the annular cavity. The main light source assembly is arranged in the main cavity and is used to emit light downward of the lampshade. The backlight assembly is arranged in the annular cavity and is arranged obliquely upward toward the outside of the lampshade, and is used to emit light obliquely upward toward the outside of the lampshade. In this structure, the backlight assembly outside the lampshade of the ceiling lamp emits light obliquely upward, so that the ceiling lamp has the function of background light. However, this method uses a direct lighting method to generate background light, only changing the light irradiation direction through a simple structure, making the light irradiate along the edge of the lamp body. When used as a night light, it causes discomfort due to the direct irradiation of light on the eyes.

[0004] In view of this, overcoming the above-mentioned defects of the prior art is an urgent problem to be solved in this technical field. Summary of the Utility Model

[0005] Aiming at the technical problems mentioned in the background art, the purpose of the utility model is to provide a ceiling lamp to solve the technical problems mentioned in the above background art.

[0006] To achieve the above object, the technical solution provided by the present utility model is as follows: A ceiling lamp includes a lamp body and a hanging plate. The lamp body and the hanging plate are movably fixed by a detachable mechanism. The lamp body has a front and a back. A chamber space for installing the main lighting component is provided on the front. The back of the ceiling lamp is integrally provided with a platform, a lamp groove, and an inclined surface. A backlight is provided on the outer wall surface of the platform. The lamp groove is engaged with a light guide cover by a clamping mechanism. The backlight is in the lamp groove formed in a sealed state between the light guide cover and the outer wall surface of the platform. The inclined surface is arranged around the outer edge of the lamp groove. The axial height of the light guide cover is higher than that of the inclined surface. An out-light gap is provided between the inclined surface and the installed ceiling. After the light of the backlight is refracted by the light guide cover and reflected by the inclined surface, it is projected from the out-light gap to the ceiling around the circumference of the lamp body.

[0007] Compared with the prior art, the beneficial effect of the present utility model is that: a distance is formed between the inclined surface and the installed ceiling to form an out-light gap. After the light of the backlight is refracted by the light guide cover and reflected by the inclined surface, it is projected from the out-light gap to the ceiling around the circumference of the lamp body, so that a background light surface is formed on the ceiling along the circumference of the lamp body. The line of sight of the user's eyes and the light of the backlight are misaligned, and the eyes will not directly contact the light source, achieving a hidden installation method of the backlight and reducing the harm of light to the eyes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Such as Figures 1 to 6As shown in the figure, a ceiling lamp includes a lamp body 1 and a hanging plate 2. The lamp body 1 has a front side and a back side. The front side is provided with a light-emitting surface 31 of the main lighting component. Inside the front side, there is a chamber space 11 for the main lighting component 3. When the ceiling lamp is installed on the ceiling 6, the lighting direction of the main lighting component 3 is downward. At the center position of the front wall surface of the lamp body 1, a circular protrusion 12 protrudes. The circular protrusion 12 forms a sunken circular recess 13 corresponding to the center position of the back side of the lamp body 1. The side surface of the circular protrusion 12 extends to form a reinforcing strip 14 reaching the edge of the lamp body 1. There are 7 reinforcing strips 14. The reinforcing strips 14 are integrally formed with the lamp body 1. The number of reinforcing strips 14 can also be increased or decreased according to the size of the lamp. The reinforcing strips 14 enhance the stress extrusion coefficient of the lamp body 1 and ensure the integrity of the whole lamp when it is pressed by the center of gravity during transportation or accidentally dropped during installation. In addition, the height of the reinforcing strips 14 is the same as the protruding height of the circular protrusion 12. There are grid positions 15 formed between the reinforcing strips 14. The grid positions 15 can accommodate a circuit board, which can be a control circuit board or a power circuit board. At the center position of the back side of the lamp body 1, there is a circular recess 13. On the wall body of the circular recess 13, there is a rotary buckle 16. On the outer wall surface at the lower end of the hanging plate 2, there is a hanging plate rotary buckle 21. The rotary buckle 16 and the hanging plate rotary buckle 21 are buckled and can be rotated clockwise or counterclockwise to complete fixation or disassembly. The hanging plate rotary buckle 21 is rotated into the circular recess 13. The hanging plate 2 and the back side of the lamp body 1 are close to the same horizontal line, ensuring the flatness of the back side of the ceiling lamp. The back side of the ceiling lamp is integrally provided with a platform 17, a lamp slot 18, and an inclined surface 19. The platform 17 is circular. The platform 17 is arranged around the edge of the circular recess 13. On the outer wall surface of the platform 17, there is a backlight 4. The backlight 4 is strip-shaped and is attached to the outer wall surface of the platform 17 in a circular shape. Above the edge of the platform 17, there is a step 171. The lamp slot 18 is arranged adjacent to the edge of the platform 17. On the bottom wall of the lamp slot 18, there are 8 card holes 181. The number of card holes 181 can also be increased or decreased according to actual needs. A light guide cover 20 is engaged with the lamp slot 18. At the lower end of the light guide cover 20, there is a buckle 201. The buckle 201 is aligned with the card hole 181 to complete the engagement. The light guide cover 20 is fixed in the lamp slot 18. The backlight 4 is in the lamp slot 18 in a sealed state formed between the light guide cover 20 and the outer wall surface of the platform 17. The inner side surface at the upper end of the light guide cover 20 is engaged with the step 171, making the upper end of the light guide cover 20 and the platform 17 at the same horizontal plane. The inclined surface 19 is arranged around the outer edge of the lamp slot 18. The inclined surface 19 slopes obliquely downward at an acute angle inward from the edge gap of the lamp body 1 towards the lamp slot 18 and is engaged with the edge of the lamp slot 18. At the joint 191 between the inclined surface 19 and the lamp slot 18, a wall surface 192 is vertically provided on the lamp slot 18. When the diameter of the lamp body is 300 mm, the angle formed by the inclined surface 19 and the horizontal line is 25 degrees. The light guide cover 20 is engaged and installed at the lamp slot 18. The axial height of the light guide cover 20 is higher than that of the inclined surface 19, forming a light-emitting gap 5 between the inclined surface 19 and the installed ceiling 6. The light of the backlight 4 is refracted by the light guide cover 20 and reflected by the inclined surface 19, and then projected from the light-emitting gap 5 to the ceiling 6 around the circumference of the lamp body 1, forming a background light surface 22 on the ceiling 6 along the circumference of the lamp body 1.

[0016] When the ceiling lamp is installed and used, the hanging plate 2 is separated from the lamp body 1 by a snap structure. The hanging plate 2 is fixed to the ceiling 6 by screws. The snap 16 of the lamp body 1 is aligned with the snap 21 of the hanging plate to complete the engagement, and then the installation is completed. When the backlight 4 works, the backlight 4 irradiates towards the edge of the lamp body 1. Some of the light rays of the backlight 4 directly irradiate out of the edge of the lamp body 1, and some of the light rays of the backlight 4 also irradiate on the inclined surface 19. The inclined surface 19 reflects the light rays to the light guide cover 20 or the ceiling 6. Both the light guide cover 20 and the ceiling 6 will diffusely reflect the light rays on the inclined surface 19, which will also cause a large amount of light to irradiate out of the lamp body 1 from the light-emitting gap 5, thereby generating background light. The backlight 4 irradiates a light circle with a diameter of 3 - 5 cm along the circumference of the lamp body 1, forming a background light surface 22 along the circumference of the lamp body on the ceiling, which has a lighting effect. The line of sight of the user's eyes is misaligned with the light rays of the backlight 4, and the eyes will not be in direct visual contact with the light source, reducing the harm of light to the eyes.

[0017] Installed on the ceiling of the bedroom for use, the main lighting component 3 of the ceiling lamp is used for regular lighting. When people are sleeping, the main lighting component 3 is turned off, and the background light of the ceiling lamp can be turned on to serve as a night light. The backlight 4 that generates the background light is hidden on the back of the lamp body 1 of the ceiling lamp. The light rays of the background light irradiate out of the lamp body 1 from the light-emitting gap 5. The backlight 4 does not directly irradiate the eyes, reducing the eye discomfort caused by the direct irradiation of the eyes and the light source.

[0018] The ceiling lamp can be installed on the ceiling 6 for use, or it can also be installed on the wall.

[0019] The hanging plate 2 and the lamp body 1 are fixed in a detachable manner by a snap mechanism, or it can also be a threaded rotary movable fixation. For the threaded rotary movable fixation, threads are provided on the outer wall surface at the lower end of the hanging plate 2, and threads corresponding to the threads in the hanging plate 2 are provided on the wall surface of the circular concave position 13 of the lamp body 1. The threads of the hanging plate 2 and the threads of the lamp body 1 can be screwed together, and the fixation or disassembly is completed by rotating clockwise or counterclockwise.

[0020] According to the different diameters of the lamp body 1 of the ceiling lamp, to ensure that the inclined surface 19 can reflect the light rays of the backlight 4 outside the lamp body 1, when producing the lamp body, the inner acute angle of the inclined surface 19 can be adjusted, and the inner acute angle of the inclined surface 19 is 20 - 65 degrees.

[0021] The backlight 4 is provided with a variety of color changes, and the color of the background light can be adjusted through a remote control or an APP according to the user's preferences.
