Description

Technical Field

[0001] The present application relates to the field of lighting fixtures, and in particular to a lamp. Background Art

[0002] With the continuous progress and development in the field of modern lighting, space lighting has become an indispensable part. Consumers and designers have diversified requirements for the selection of lighting fixtures. Wall washer or atmosphere lamp is a kind of lamp used for night scene lighting and architectural decoration lighting. Existing wall washer or atmosphere lamp often uses exposed or transparent dripping lamp beads to directly illuminate the receiving surface, but it is easy to have problems such as small wall washing range and low light utilization. Utility Model Content

[0003] In view of this, an embodiment of the present application provides a lamp to solve the above technical problems.

[0004] The embodiment of the present application provides a lamp, which is used to illuminate a light receiving surface. The lamp includes a circuit board, a first light source and a reflector. The first light source is arranged on the circuit board, and the first light source has a light emitting surface, and the light emitting surface is suitable for facing the light receiving surface. The reflector is connected to the circuit board and arranged on one side of the first light source, and the reflector has a reflective surface, which is located on the light path of the first light source and is used to reflect the light of the first light source to the light receiving surface.

[0005] In some embodiments, the reflective surface is a concave surface formed on the surface of the reflective element.

[0006] In some embodiments, the concave surface is a spherical surface, and the center of the spherical surface is arranged on the plane where the circuit board is located.

[0007] In some embodiments, the concave surface is an aspherical surface.

[0008] In some embodiments, the surface of the reflective element is recessed to form a receiving groove, the reflective surface is the inner wall of the receiving groove, and the first light source is disposed in the receiving groove.

[0009] In some embodiments, the reflector forms a receiving groove, and the reflective surface is the inner wall of the receiving groove. The reflector also includes a light mixing plate, which covers the receiving groove, and the light reflected by the reflective surface transmits the light mixing plate and propagates toward the light receiving surface.

[0010] In some embodiments, the light emitting surface is adapted to be parallel to the light receiving surface, and the angle between the light mixing plate and the light emitting surface is an acute angle. When projecting toward the plane where the light emitting surface is located in a direction perpendicular to the light emitting surface, the projection of the light mixing plate covers a portion of the light emitting surface, so that at least part of the light of the first light source can be directly emitted through the light mixing plate.

[0011] In some embodiments, the light emitting surface is adapted to be parallel to the light receiving surface. When projecting toward the plane where the light emitting surface is located in a direction perpendicular to the light emitting surface, the projection of the light reflecting surface does not completely cover the light emitting surface, so that part of the light from the first light source is reflected by the light reflecting surface, and part of the light is not reflected and directly propagates in the direction where the light receiving surface is located.

[0012] In some embodiments, there are multiple reflectors and multiple first light sources. The multiple first light sources are sequentially arranged on the circuit board, the multiple reflectors are arranged one by one with the multiple first light sources, and the light of each first light source is emitted through a corresponding reflector.

[0013] In some embodiments, the lamp further includes a plurality of second light sources, which are arranged alternately with the plurality of first light sources in the length direction of the circuit board, and light from the second light sources is directly emitted to the light receiving surface.

[0014] Compared with the prior art, the embodiment of the present application provides a lamp, which includes a circuit board, a first light source and a reflector. In the lamp provided by the embodiment of the present application, by arranging the reflector on one side of the first light source, the light generated by the first light source can be reflected to the light receiving surface via the reflective surface of the reflector, which can concentrate the light generated by the light source on the reflector to improve the light utilization rate. On the other hand, the reflector can be directed toward the illuminated area to prevent the light from irradiating other non-illuminated areas, thereby increasing the irradiation range and irradiation brightness of the light source, thereby improving the wall washing effect.

[0015] Furthermore, in some embodiments, the light emitting surface of the first light source faces the light receiving surface, and the reflector only needs to be fastened to the circuit board to realize the lighting of the lamp, and no additional receiving frame or mounting bracket for mounting the reflector is required, which can save installation and maintenance costs, and also avoid the problem of poor compatibility between the reflector and the receiving frame or mounting bracket, and poor installation and fixing effect. In addition, the embodiment of the present application provides a lamp that is suitable for a smaller installation area and can provide lighting for more application scenarios.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] See also Figure 1 and Figure 2, an embodiment of the present application provides a lamp 100. In this embodiment, the lamp 100 is used to provide lighting or emit light to a light receiving surface 50, and the lamp 100 can be a wall washer or an atmosphere lamp. The light receiving surface 50 can be a ceiling, a wall, a ground, etc. As an example, the lamp 100 is a wall washer, which is used to provide lighting for the wall. As another example, the lamp 100 is an atmosphere lamp, which can be installed on the back of a display screen such as a TV or on a stage wall, stairs, etc., to play a decorative role. When the lamp 100 is installed on the back of a TV display screen, the illumination range of the atmosphere lamp can be increased to prevent the light from being covered by the display screen, thereby improving the user's visual experience.

[0027] In an embodiment provided in the present application, a lamp 100 is used to illuminate a light receiving surface 50. The lamp 100 includes a circuit board 10, a first light source 20 and a reflector 30. The first light source 20 is disposed on the circuit board 10. The first light source 20 has a light emitting surface 21. The light emitting surface 21 is suitable for facing the light receiving surface 50. The reflector 30 is connected to the circuit board 10 and disposed on one side of the first light source 20. The reflector 30 has a reflecting surface 31. The reflecting surface 31 is located on the optical path of the first light source 20, so as to reflect the light of the first light source 20 to the light receiving surface 50. By arranging the reflector 30 on one side of the first light source 20, the light generated by the first light source 20 can be reflected to the light receiving surface 50 via the reflecting surface 31 of the reflector 30. On the one hand, the light generated by the light source can be concentrated on the reflector 30, thereby improving the light utilization rate. On the other hand, the reflector 30 can greatly improve the irradiation range and irradiation brightness of the light source, thereby improving the wall washing effect. At the same time, the light emitting surface 21 of the first light source 20 is parallel to the light receiving surface 50, and the reflector 30 only needs to be fastened to the circuit board 10 to realize the lighting of the lamp 100, and there is no need to add an additional receiving frame or mounting bracket for mounting the reflector 30, which can save installation costs and maintenance costs, and also avoid the problem of poor compatibility between the reflector 30 and the receiving frame or mounting bracket, and poor installation and fixing effect. In addition, the embodiment of the present application provides a lamp 100 that is suitable for installation areas with smaller spaces, and can provide lighting for more application scenarios. As an example, the light receiving surface 50 is a vertical plane (such as a wall), and the light emitting surface 21 of the light source is suitable for being parallel to the light receiving surface 50. The height of the designated area 51 in the vertical direction of the light receiving surface 50 is higher than the height of the light emitting surface 21 in the vertical direction, which can achieve the effect of seeing the light but not the lamp, and avoid the lamp from blocking the user's line of sight at a certain angle, thereby improving the user's viewing experience. Specifically, the light receiving surface 50 extends along the vertical direction, the plane where the light emitting surface 21 is located is a vertical plane, and the height of the horizontal plane where the light emitting surface 21 is located is lower than the height of the horizontal plane where the designated area 51 is located. Further, when projecting onto the light receiving surface 50 along the normal direction of the light emitting surface 21, the projection of the light emitting surface 21 and the projection of the designated area 51 are arranged side by side, and there is no overlap between the two. Since the circuit board 10 and the light receiving surface 50 are roughly parallel, the first light source 20 is arranged on the side of the circuit board 10 facing the light receiving surface 50. At this time, from the user's perspective, the circuit board 10 blocks the first light source 20, and the light-emitting part of the first light source 20, such as the lamp beads, is not visible, and the visual effect is better.

[0028] As another example, the light receiving surface 50 is a horizontal plane (such as a ceiling or the ground), the light emitting surface 21 of the light source is adapted to be parallel to the light receiving surface 50, and the designated area 51 does not overlap with the projection of the light emitting surface 21 when projected along the light receiving surface 50. Specifically, the light receiving surface 50 extends in the horizontal direction, the plane where the light emitting surface 21 is located is a horizontal plane, and when the vertical plane where the light emitting surface 21 is located is projected along the light receiving surface 50, the projection of the light emitting surface 21 is arranged side by side with the designated area 51, and there is no overlap between the two.

[0029] Next, each component of the lamp housing module 100 and the specific structure of each component will be introduced one by one.

[0030] See also Figure 2 In this embodiment, the circuit board 10 is used to provide electric energy for the first light source 20, so as to realize the internal and external conduction between the first light source 20 and the external circuit. The circuit board 10 is roughly in the shape of a long plate, and the first light source 20 is arranged on the circuit board 10. As an example, when the number of the first light sources 20 is multiple, the multiple first light sources 20 are arranged on the circuit board 10 in sequence and at intervals, for example, arranged along the length direction of the circuit board 10. The circuit board 10 is attached to the mounting surface, and the circuit board 10 can be a flexible circuit board or a printed circuit board. The mounting surface can be a wall, a floor, the back of a display screen, a stage decoration surface or other supporting surface. As an example, the circuit board 10 is attached to the back of the display screen, and the reflective surface 31 is arranged toward the side away from the back of the display screen. The light generated by the lamp 100 is arranged around the back of the display screen, forming a light effect surrounding the display screen, thereby improving the visual experience of the user. The reflective surface 31 can further improve the utilization rate of light, increase the light effect area, and thus improve the lighting brightness of the lamp 100. In this embodiment, the circuit board 10 is a flexible circuit board 10. The flexible circuit board 10 has the characteristics of high wiring density, light weight, thin thickness, and good bending performance. It can be used as a wire to connect all the first light sources 20 into a string. At the same time, it can be bent up, down, left, and right at will, which is convenient for installation.

[0031] In the present embodiment, the first light source 20 is arranged on the circuit board 10, and is used to provide illumination or emit light to the light receiving surface 50. As an example, the first light source 20 is detachably connected to the circuit board 10, which is convenient for the maintenance and replacement of the first light source 101. In the present embodiment, the first light source 20 is an incoherent light source, and the first light source 20 can be a high-pressure gas light source such as a halogen light bulb, UHP (ultra-high pressure mercury bulb), UHE (ultra-high pressure mercury bulb) or an LED light source, etc. In the present embodiment, the first light source 20 is an LED light source, which can be a single-color LED lamp bead or a three-color LED lamp bead. On the one hand, it can improve the efficiency of converting electrical energy into light energy, thereby reducing energy waste. At the same time, the heat generated by the LED light source during illumination is less, which plays a role in energy saving and environmental protection; on the other hand, the LED light source has a long service life, which reduces the frequency of light source replacement and thus reduces the cost of use. At the same time, LED can avoid damage to human eyes and improve safety of use.

[0032] In the embodiment of the present application, the reflector 30 is used to reflect the light generated by the first light source 20 to the light receiving surface 50. The reflector 30 is connected to the circuit board 10 and is arranged on one side of the first light source 20. The reflector 30 includes a first connecting wall 32, a second connecting wall 33 and a third connecting wall 34. The first connecting surface 32 and the third connecting surface 34 are arranged in parallel and spaced apart, and the two sides of the second connecting surface 33 are respectively connected to the first connecting surface 32 and the second connecting surface 34. The reflective surface 31 is arranged in the area surrounded by the first connecting wall 32, the second connecting wall 33 and the third connecting wall. The first connecting surface 32, the second connecting surface 33 and the third connecting surface 34 are integrally injection molded, which can avoid the phenomenon of incompatibility of the sizes of the connecting surfaces and improve the production rate. In some embodiments, the first connecting surface 32 and the third connecting surface 34 are both translucent materials. In addition to being emitted to the light receiving surface 50 through the light emitting area away from the reflective surface 31, the light generated by the first light source 21 can also be emitted through the first connecting surface 32 and the third connecting surface 34. Specifically, the lamp 100 can be used for staircase decoration or the back decoration of a display screen. As an example, most of the light generated by the first light source 20 is reflected by the reflector 30 to the wall above the stairs for concentrated lighting, and a small part of the light can be emitted from the first connecting surface 32 and the third connecting surface 34 to illuminate or decorate the step surface. As another example, the lamp is installed on the back of the display screen, and the light generated by the first light source is arranged around the back of the display screen to form a light effect surrounding the display screen. On the one hand, it can further improve the lighting range and lighting brightness of the lamp 100 and improve the wall washing effect; on the other hand, it can improve the light utilization rate and also play a certain decorative role. The above-mentioned light-transmitting materials may include one or more of the following: glass, light-transmitting plastic, acrylic, polycarbonate, etc., which are not limited in this embodiment.

[0033] In this embodiment, the reflective surface 31 is the area of ​​the reflector 30 used to reflect light. The side edges of the reflective surface 31 are respectively connected to the first connecting surface 32, the second connecting surface 33 and the third connecting surface 34 and are arranged on the light path of the first light source 20, so as to reflect the light of the first light source 20 to the light receiving surface 50. The reflective surface 31 extends upward from the side of the reflector 30 close to the first light source 20 to the side of the reflector 30 away from the first light source 21, and it can be a curved surface. The concave direction of the curved surface is toward the side of the first light source 20, that is, the reflective surface 31 is a concave surface forming the surface of the reflector 30. Explained from another perspective, the surface of the reflector 30 is concave to form a receiving groove 35, and the reflective surface 31 is the inner wall of the receiving groove 35, and at least part of the structure of the first light source 20 is arranged in the receiving groove 35. Part of the light generated by the first light source 20 that is emitted toward the reflective surface 31 (in the downward direction in the figure) can be reflected to the light receiving surface 50 via the reflection of the reflective surface 31. On the one hand, the lighting range and lighting brightness of the lamp 100 can be increased, and the wall washing effect can be improved; on the other hand, part of the light emitted toward the reflective surface 31 (in the downward direction in the figure) can be emitted to the light receiving surface 50 after reflection, which can improve the light utilization rate. Furthermore, the spacing between the reflective surface 31 and the first light source 20 is as small as possible. On the one hand, the structure of the reflective member 30 can be made compact, the volume of the reflective member 30 can be reduced, the installation space can be saved, it is suitable for a smaller installation area, and can be applied to more usage scenarios. On the other hand, it is convenient for the light of the first light source 20 to directly enter the reflective surface 31 after being emitted, which greatly shortens the reflection light path of the first light source 20 and improves the reflection efficiency.

[0034] See also Figures 2 to 5In the embodiment of the present application, the angle between the reflective surface 31 and the plane where the light emitting surface 21 is located is an acute angle. The light emitting surface 21 is the inner wall surface of the first light source 20 close to the light-emitting body, and the light-emitting body can be specifically an LED lamp bead. The plane where the light emitting surface 21 is located is the extension surface of the light emitting surface 21 along the direction of the inner wall surface. As an example, the light emitting surface 21 is a vertical plane, and is suitable for being parallel to the light receiving surface 50. When the reflective surface 31 is projected toward the plane where the light emitting surface 21 is located in a direction perpendicular to the light emitting surface 21, the projection of the reflective surface 31 does not completely cover the light emitting surface 21, so that part of the light of the first light source 20 is reflected through the reflective surface 31, and part of the light is not reflected and directly propagates in the direction where the light receiving surface 50 is located. The above-mentioned setting can reflect the light emitted by the first light source 20 close to the reflective surface to the light receiving surface 50 through the reflective surface 31, thereby increasing the illumination range of the first light source 20 and improving the wall washing effect. As an example, the angle between the reflective surface 31 and the plane where the light emitting surface 21 is located ranges from 15° to 60°. For example, the angle between the reflective surface 31 and the light emitting surface 21 can be 15°, 30°, 45°, 60°, etc. It should be noted that the angle between the reflective surface 31 and the light emitting surface 21 can also be in the range of other angles, which is not limited in the present embodiment.

[0035] As an example, the concave surface of the reflective surface 31 can be a spherical surface, and the center of the spherical surface is set on the plane where the circuit board 20 is located, which can collect light and make the light emitted from the light-emitting surface 21 evenly distributed. Specifically, the first light source 20 has a geometric center. When the light-emitting surface 21 is placed vertically, the horizontal plane where the geometric center of the first light source 20 is located does not coincide with the horizontal plane where the end of the reflective surface 31 away from the first light source 20 is located, and the horizontal plane where the geometric center of the first light source 20 is located is located above the horizontal plane where the end of the reflective surface 31 away from the first light source 20 is located. The above-mentioned setting can enable the multiple beams of light generated by the first light source 20 to be reflected to different positions of the light receiving surface 50 through different areas of the reflective surface 31, thereby improving the lighting range of the lamp 100. In addition, the spherical surface can make the light more uniform. At the same time, the reflective surface 31 also has a focusing effect, which can converge the light generated by the first light source 20 to the area required to be irradiated on the light receiving surface 50, or realize a predetermined light spot shape, thereby improving the light utilization rate. As another example, the outer contour of the concave surface may also be a non-spherical surface, such as a spherical surface, an ellipsoidal surface, a free-form surface, etc., which is not limited in this embodiment.

[0036] In this embodiment, the reflector 30 further includes a light mixing plate 36, which is arranged on the light path of the first light source 20. When the first light source 20 is a plurality of monochromatic and different color lamp beads or a red, green, blue and multi-color lamp beads, the light generated by the first light source 20 is reflected to the light mixing plate 36 via the reflective surface 31, and the light mixing plate 36 is used to achieve light mixing and make the light more uniform and free of variegated colors. The light mixing plate 36 can be one or more of the following: a white translucent diffuser, a glass diffuser, a patterned plate, etc. This embodiment is not limited to this. In some embodiments, the light mixing plate 36 is also provided with a microstructure, which is used to change the direction of the light, thereby solving the color mixing problem of two-color, variegated and multiple lamp beads. The microstructure can be a protrusion or depression in the shape of a pyramid, a prism, a sphere, etc. arranged in an array. The microstructure does not have to completely cover the light mixing plate 36. As an example, the size and shape of the microstructure setting area and the light emitting area of ​​the reflector 30 match. In this embodiment, the reflector 30 forms a receiving groove 35, the reflective surface 31 is the inner wall of the receiving groove 35, and the light mixing plate 36 covers the receiving groove 35. The light mixing plate 36 can not only be used for the above-mentioned light mixing, but also play a certain protective role for the components in the reflector 30.

[0037] In this embodiment, the angle between the light mixing plate 36 and the plane where the light emitting surface 21 is located is an acute angle. The light emitting surface 21 is suitable for being parallel to the light receiving surface 50. When the light mixing plate 36 is projected toward the plane where the light emitting surface 21 is located in a direction perpendicular to the light emitting surface 21, the projection of the light mixing plate 36 covers a part of the light emitting surface 21, so that part of the light of the first light source 20 that is not reflected by the reflective surface 31 can be directly emitted through the light mixing plate 36. The part of the light emitted directly through the light mixing plate 36 can reduce the loss of light energy to a certain extent, and can improve the illumination brightness on the light receiving surface 50 to a certain extent. At the same time, it can cover the area that the light emitted after being reflected by the reflective surface cannot illuminate, thereby increasing the illumination range. As an example, the angle between the light mixing plate 36 and the light emitting surface 21 has an angle value range of 15° to 75°. For example, the angle between the light mixing plate 36 and the light emitting surface 21 can be 15°, 30°, 45°, 75°, and the like. It should be noted that the value range of the angle between the light mixing plate 36 and the light emitting surface 21 may also be other angles, which is not limited in this embodiment.

[0038] See also Figure 3In the embodiment of the present application, the number of reflectors 30 is multiple, and the number of first light sources 20 is also multiple. As an installation and use example, multiple first light sources 20 are arranged in sequence and spaced apart on the circuit board 10, and multiple reflectors 30 are arranged one-to-one with the multiple first light sources, so that the light of the first light source 20 is emitted through a corresponding reflector 33. On the one hand, the above example can increase the lighting range of the first light source 20 and improve the wall washing effect. On the other hand, maintenance and management are simple. When any one of the multiple reflectors 30 is damaged, the user only needs to replace the damaged reflector, thereby increasing the service life of the lamp 100.

[0039] See also Figure 6 In some other embodiments, the lamp 100 further includes a plurality of second light sources 40, and the second light sources 40 are used to emit light to the light receiving surface 50. Specifically, the second light source 40 is detachably connected to the circuit board 10, so as to facilitate the maintenance and replacement of the second light source 40. In this embodiment, the second light source 40 is an incoherent light source, and the second light source 40 can be a high-pressure gas light source such as a halogen light bulb, UHP (ultra-high pressure mercury bulb), UHE (ultra-high pressure mercury bulb) or an LED light source, etc. In this embodiment, the second light source 40 is an LED light source, which can be a single-color LED lamp bead or a three-color LED lamp bead. On the one hand, it can improve the efficiency of converting electrical energy into light energy, thereby reducing energy waste. At the same time, the heat generated by the LED light source during illumination is less, which plays a role in energy saving and environmental protection; on the other hand, the LED light source has a long service life, which reduces the frequency of light source replacement and thus reduces the cost of use. At the same time, LED can avoid damage to human eyes and improve safety in use.

[0040] As another example of installation and use, a plurality of second light sources 40 and a plurality of first light sources 20 are arranged alternately in the length direction of the circuit board 10, and the light of the second light source 40 is directly emitted to the light receiving surface 50, and the light of the first light source 20 is emitted to the light receiving surface 50 via the reflector 30. The above arrangement can ensure that a part of the light of the lamp 100 can be irradiated to the light receiving surface 50, meeting the user's lighting range requirements for the light receiving surface 50. At the same time, the second light source 40 can increase the lighting brightness of the light receiving surface 50, avoid the appearance of dark areas on the light receiving surface 50, further increase the lighting area of ​​the light receiving surface 50, and improve the wall washing effect. It should be noted that the alternating arrangement can be to set the first light source 20 for every second light source 40, or to set a first light source 20 for every two second light sources 40, or to set a first light source 20 for every other number of second light sources 40. The embodiment of the present application does not limit the number of second light sources 40 between adjacent first light sources 20. The second light sources 40 with different intervals are set depending on the user's lighting requirements for the light receiving surface 50, and the number of intervals can be set according to the lighting effect.

[0041] In summary, the embodiment of the present application provides a lamp 100, which includes a circuit board 10, a first light source 20 and a reflector 30. In the lamp 100 provided in the embodiment of the present application, by arranging the reflector 30 on one side of the first light source 20, the light generated by the first light source 20 can be reflected to the light receiving surface 50 via the reflective surface 31 of the reflector 30, which can concentrate the light generated by the light source on the reflector 30, thereby improving the light utilization rate. On the other hand, the reflector can be oriented toward the illuminated part to prevent the light from irradiating other non-illuminated parts, thereby improving the irradiation range and irradiation brightness of the light source, thereby improving the wall washing effect. Further, in some embodiments, the light emitting surface 21 of the first light source is oriented toward the light receiving surface 50, and the reflector 30 only needs to be fastened to the circuit board 10 to achieve large-scale lighting of the lamp, and there is no need to add an additional receiving frame or mounting bracket for mounting the reflector 30, which can save installation costs and maintenance costs, and also avoid the problem of poor compatibility between the reflector 30 and the receiving frame or mounting bracket, and poor installation and fixing effect. In addition, the lamp 100 provided in the embodiment of the present application is adaptable to installation areas with smaller spaces and can provide lighting for more application scenarios.
