Detailed Description
Fig. 1 is a schematic structural diagram of a lighting assembly according to an aspect of an embodiment of the present invention. Referring to fig. 1, in some embodiments, a lighting assembly 10 for a household appliance includes a bracket 12 having a through hole 14. The through hole 14 may penetrate the holder 12.
The lighting assembly 10 includes a lamp housing 16. The globe 16 and the support 12 define a space 18. The globe 16 includes a plate-shaped light exit portion 20. A space 18 may be located between the globe 16 and the support frame 12.
The lighting assembly 10 includes a circuit substrate 22 mounted to the frame 12 and located outside the space 18. The circuit substrate 22 may be opposed to the light emergent portion 20.
The lighting assembly 10 includes a light emitting device 24 mounted to the circuit substrate 22. The light emitting device 24 may include a light emitting diode. The light emitting device 24 may face the light exit part 20.
The lighting assembly 10 includes a lens 26 that covers the light emitting device 24 to refract light from the light emitting device 24. The lens 26 is located in the space 18 through the through hole 14. The lens 26 may be located between the light emitting device 24 and the light exit portion 20.
The embodiment of the invention can help to reduce space requirements, ensure lighting effects and the like.
For example, the lens 26 is located in the space 18 through the through hole 14, which is beneficial to avoid the overlapping of the thickness of the lens 26 and the bracket 12 outside the space 18, and reduce the thickness of the lighting assembly 10. The plate-shaped light emitting portion 20 may contribute to a smaller height of the light emitting portion 20, and reduce the thickness of the lighting assembly 10. The circuit substrate 22 located outside the space 18 may be beneficial to ensure the light mixing distance M and the light emitting uniformity of the lighting assembly 10. As such, and so on. That is to say, the lighting assembly 10 can achieve a better lighting effect with a lower thickness, reduce the space requirement, ensure the lighting effect, and provide a surface light source with uniform light emission. The light mixing distance M may be a distance between the light emitting device 24 and the light exit part 20.
In some embodiments, the thickness of the circuit substrate 22 is absorbed by the thickness of the support 12.
As such, the thickness of the lighting assembly 10 may be advantageously reduced. The circuit substrate 22 may be located within the thickness of the support 12 such that the thickness of the circuit substrate 22 is absorbed by the thickness of the support 12.
In some embodiments, the bracket 12 includes a mounting wall 28 and a mounting slot 30 recessed from the mounting wall 28 toward the light exit portion 20, the circuit substrate 22 is at least partially positioned within the mounting slot 30, and the light emitting device 24 faces the light exit portion 20.
In this manner, it may be facilitated that part or all of the thickness of the circuit substrate 22 is absorbed by the thickness of the support 12, and the light emitted from the light emitting device 24 is transmitted outward through the light exit portion 20.
When the circuit substrate 22 is partially positioned within the mounting slot 30, a portion of the thickness of the circuit substrate 22 may be absorbed by the thickness of the bracket 12. When the circuit substrate 22 is positioned entirely within the mounting slot 30, the entire thickness of the circuit substrate 22 may be absorbed by the thickness of the bracket 12.
In some embodiments, the canopy sidewalls 32 of the canopy 16 are positioned outside of the frame sidewalls 34 of the frame 12, with a space between the distal ends 36 of the frame sidewalls 34 and the light exit portion 20.
Therefore, light refracted by the lens 26 is reflected and scattered by the bracket side wall 34 and the lampshade side wall 32 and then is transmitted out of the light outlet part 20, the light path is complete, the light is uniform in light emission, and no shadow related to the branch side wall 34 exists.
The holder side walls 34 may have a height less than the canopy side walls 32 so that the end 36 is spaced from the light exiting portion 20 when the holder 12 is coupled to the canopy 16.
Figure 2 is a schematic perspective view of the lighting assembly of figure 1 without the lamp housing. Referring to fig. 2, in some embodiments, the holder 12 includes a protrusion 38 on the inner side, the protrusion 38 being spaced from the end 36 of the holder sidewall 34.
This can facilitate the molding of the mold and prevent the shape of the protruding portion 38 from affecting the optical uniformity of the light-emitting portion 20 and causing a poor shadow. The projections 38 may project inwardly from the bracket side walls 34.
The holder 12 may be in the form of an elongated box open at one side. The protrusions 38 may be provided in plurality and spaced apart from each other on the opposing longitudinal shelf sidewalls 34.
The lens 26 may be a plurality of spaced apart mounting walls 28 projecting between the bracket side walls 34. The light emitting devices 24 may be plural and may correspond one-to-one to the lenses 26.
Figure 3 is another schematic view of the lighting assembly of figure 1. Referring to fig. 3, in some embodiments, the minimum distance D between the protrusion portion 38 and the light-emitting portion 20 is not less than 6 mm.
This is advantageous in preventing the shape of the projection 38 from affecting the optical uniformity of the light-emitting portion 20 and causing poor shading.
Numerical values herein may include numerical values within the error range of measurement, metrology, and the like. The error range may be plus or minus five percent. For example, 6 millimeters may include 5.7 millimeters, 5.9 millimeters, 6 millimeters, 6.2 millimeters, 6.3 millimeters, and so forth.
The projection 38 may extend diagonally between the mounting wall 28 and the bracket side wall 34. The minimum distance D between the protrusion 38 and the light emergent portion 20 may be a linear distance between the protrusion 38 closest to the light emergent portion 20 and the light emergent portion 20. The portion of the protrusion 38 that meets the bracket side wall 34 may be rounded.
Figure 4 is an exploded perspective schematic view of the lighting assembly of figure 1. As shown in fig. 4, in some embodiments, globe 16 includes globe sidewalls 32 for coupling with frame 12, frame 12 includes frame sidewalls 34 for coupling with globe sidewalls 32, and globe sidewalls 32 include snap holes 40 for snap-fitting coupling with frame sidewalls 34.
So, can help setting up buckle structure on support 12, and no buckle structure on the lamp shade 16, it is bad to avoid buckle structure to form optics at light-emitting portion 20, and light-emitting portion 20 can not see luminescent device 24 or other optics abnormal points moreover, the shaping surface is even smooth, convenient even light-emitting.
The lamp housing 16 may have a shape of a strip box with an opening at one side corresponding to the holder 12. The plurality of fastening holes 40 may be spaced apart from and arranged in a row on the two opposite lengthwise sidewalls 32 of the lampshade, and cooperate with the plurality of fasteners 41 on the outer surface of the corresponding side wall 34 of the rack, so that the lampshade 16 and the rack 12 can be fastened together at multiple positions, and are stable and reliable.
Figure 5 is an exploded perspective schematic view of the lighting assembly of figure 1 from another angle, without the lamp housing. Referring to fig. 5, in some embodiments, the bracket 12 includes a mounting wall 28 and a mounting slot 30 recessed from the mounting wall 28 to receive the circuit substrate 22.
In this manner, the thickness of the bracket 12 can be facilitated to absorb the thickness of the circuit substrate 22.
The circuit substrate 22 may be generally elongated and may have a lateral dimension slightly smaller than the lens 26 thereon. The length and width of the circuit substrate 22 may be smaller than those of the support 12. The length and width of the mounting groove 30 may be greater than or equal to those of the circuit substrate 22. Accordingly, the length and width of the mounting groove 30 may be smaller than those of the bracket 12. The depth of the mounting groove 30 may be greater than or equal to the thickness of the circuit substrate 22. The circuit substrate 22 may be mounted in the mounting groove 30. A plurality of through holes 14 may be distributed in the mounting groove 30 at intervals to pass through the corresponding lenses 26, respectively.
In some embodiments, one of the circuit substrate 22 and the bracket 12 includes heat stake posts 42 and the other includes openings 44 that mate with the heat stake posts 42.
In this manner, the circuit substrate 22 and the bracket 12 can be advantageously fixed to each other. The heat stake 42 or the opening 44 in the bracket 12 may be located inside the mounting slot 30.
In some embodiments, the circuit substrate 22 is mounted to the bracket 12 against an outer surface of the bracket 12.
As such, the size of the lighting assembly 10 may be advantageously reduced.
Referring also to fig. 4, in some embodiments, the lighting assembly 10 includes a connector 46, and the circuit substrate 22 includes an end portion 48 connected to the connector 46.
As such, power may be facilitated to be provided to the lighting assembly 10.
The connector 46 may be connected to a power source, such as a household appliance, to provide power to the lighting assembly 10 through connection to the circuit substrate 22.
Figure 6 is an enlarged partial perspective schematic view of the lighting assembly of figure 1. Referring collectively to fig. 6, in some embodiments, the circuit substrate 22 includes a main body portion 50 having a larger lateral dimension than the end portion 48, the bracket 12 includes a clamping arm 52 opposite the main body portion 50, and a connecting slot 54 between the clamping arms 52, the end portion 48 is adapted to be coupled to the connector 46 at the connecting slot 54, and the clamping arm 52 includes resilient hook portions 56 facing each other and extending toward the connecting slot 54.
In this manner, it may be advantageous for the clamping arm 52 to limit longitudinal movement of the body portion 50, the attachment slot 54 receiving the end portion 48 and the connector 46 therein, the clamping arm 52 and the resilient hook 56 restraining lateral, longitudinal movement of the connector 46.
A retaining arm 52 may be provided at the end of the holder 12 and a connecting slot 54 may be open to the outside to facilitate access of the connector 46 from the opening to connect with the end 48. When the connector 46 enters and exits, the elastic hook 56 can be separated to both sides, and rebounds after the entry and exit are completed.
With continued reference to fig. 3, in some embodiments, the holder 12 includes a mounting wall 28 for mounting the light emitting device 24, a sloped wall 58 extending from the mounting wall 28 toward the globe 16, and a holder sidewall 34 extending from the sloped wall 58 and received within the globe 16.
Therefore, light emitted by the light emitting device 24 is reflected and scattered by the inclined wall 58 and the bracket side wall 34 after being refracted by the lens 26, so that the light mixing distance is increased, the thickness is reduced, the light emitting uniformity is improved, and uniform light emission under the condition of low thickness is realized. The cooperation of the angled wall 58 with the bracket side wall 34, etc., may facilitate control of the light angle.
In some embodiments, the bezel 16 includes a bezel sidewall 32 joined to a support sidewall 34 and a light exit portion 20 connecting the bezel sidewall 32 to cooperatively define with the support 12 a space 18 therebetween.
Therefore, the side wall 32 of the lampshade can scatter light and the light-emitting part 20 can transmit light, the light circulates and is mixed in the space 18, the light path is complete, and the light-emitting is uniform.
In some embodiments, the inner surface of the stent 12 is made of a non-specular material.
In this way, the light emitted by the light emitting device 24 is refracted by the lens 26, then is scattered on the inner surface of the support 12, and is repeatedly circulated in the space 18 formed by the lampshade 16 and the support 12, so that the light incident to the light emergent portion 20 is more uniform, and the illumination effect of the illumination assembly 10 is better.
In some embodiments, the support 12 is made of a reflective scattering material and the globe 16 is made of a transmissive scattering material.
In this way, light emitted from the light emitting device 24 is refracted by the lens 26, reflected and scattered by the bracket 12, repeatedly circulated in the space 18 formed by the lampshade 16 and the bracket 12, and scattered by the lampshade 16, so that light transmitted through the light emitting portion 20 is more uniform, and the illumination effect of the illumination assembly 10 is better.
In some embodiments, the support 12 is made of a white plastic material and the lamp enclosure 16 is made of a translucent hazy material.
In this way, the light emitted by the light emitting device 24 is reflected and scattered by the support 12 after being refracted by the lens 26, is scattered by the lampshade 16, and is repeatedly circulated in the space 18 formed by the lampshade 16 and the support 12, so that the light transmitted from the light emitting portion 20 is more uniform, and the illumination effect of the illumination assembly 10 is better. May also contribute to cost control of the lighting assembly 10.
Figure 7 is a schematic diagram of the optical path of the lighting assembly of figure 1. Referring to fig. 7, in some embodiments, the lens 26 may refract the light 25 emitted from the light emitting device 24 twice, resulting in a refracted light 27.
