Description

[Technical Field]

[0001] This invention relates to a lighting device, and more particularly to a refrigerator lighting device. [Previous Technology]

[0002] An existing refrigerator lighting device is installed on the inner wall of the refrigerator compartment to provide illumination when the user opens the refrigerator compartment. However, the existing refrigerator lighting device uses a transparent textured lampshade, which has a more obvious pearlescent effect, resulting in uneven light source throughout the refrigerator compartment. Therefore, there is still room for improvement. [Summary of the Invention]

[0003] Therefore, the object of the present invention is to provide a refrigerator lighting device that can solve at least one of the above-mentioned problems.

[0004] Therefore, the refrigerator lighting device of the present invention is suitable for installation on an inner wall of a refrigerator. The refrigerator lighting device includes a lamp holder disposed on the inner wall and including an opening; a light shield disposed on the lamp holder and covering a portion of the opening, the light shield being frame-shaped and having a light outlet; a light-emitting element disposed in the lamp holder and facing the light shield; and a lamp shade disposed on the light shield and covering the light outlet.

[0005] In some embodiments, the light shield includes a frame and a first outer hook. The frame defines the light outlet and has a first long side and a second long side opposite to the first long side. The first outer hook is formed on the first long side and defines a first slot with the frame. The light shield can be engaged with the inner wall so that the inner wall is located in the first slot.

[0006] In some embodiments, the light shield is made of an opaque material.

[0007] In some embodiments, the light shield also includes at least one second hook formed on the second long side, which can be engaged with the lamp holder.

[0008] In some embodiments, the light shield also includes at least one first inner hook formed on the first outer hook and facing the light outlet, and one side of the light shield has a joint edge that can be engaged with the first inner hook and the frame.

[0009] In some embodiments, at least one engaging hook is formed on the other side of the lampshade that can engage with the second long side.

[0010] In some embodiments, the lampshade is made of a matte material.

[0011] The present invention has at least the following effects: by setting the light-emitting element in the lamp holder and facing the light shield, the light-emitting element does not directly emit light outward toward the light shield, but is first reflected into the lamp holder by the light shield and then emitted outward from the light shield by scattering, which can improve the lighting uniformity of the refrigerator lighting device of the present invention and increase the average illuminance inside the refrigerator.

[0016] In the description of this invention, unless otherwise explicitly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0017] Referring to Figures 1 and 2, one embodiment of the refrigerator lighting device 10 of the present invention is suitable for installation on an inner wall 20 of a refrigerator compartment (not shown) for providing lighting inside the refrigerator compartment. The refrigerator lighting device 10 includes a lamp holder 1, a light shield 2, a light-emitting element 3, and a lamp shade 4.

[0018] Referring to Figures 2 to 4 and Figure 6, the lamp holder 1 is disposed on the inner wall 20 and includes an opening 11, three upper hooks 12, and three lower hooks 13 spaced apart from the upper hooks 12. The upper hooks 12 and the lower hooks 13 are made of elastic material and are used to engage the light-emitting element 3. The light shield 2 is disposed on the lamp holder 1 and covers a portion of the opening 11. The light shield 2 is frame-shaped and made of opaque material, and includes a frame 21, a first outer hook 22, five first inner hooks 23, and three second hooks 24. The frame 21 defines a light outlet 213 and has a first long side 211 and a second long side 212 opposite to the first long side 211. The first outer hook 22 is formed on the first long side 211 and defines a first slot 25 with the frame 21. The light shield 2 can be engaged with the inner wall 20, so that the inner wall 20 is located in the first slot 25. The first inner hooks 23 are formed on the first outer hook 22 and face the light outlet 213. The second hooks 24 are formed on the second long side 212 and can be engaged with the lamp holder 1. The number of the upper hooks 12, the lower hooks 13, the first inner hooks 23 and the second hooks 24 is not limited to this embodiment. Other numbers can be used in other embodiments, as long as there is at least one.

[0019] Referring to Figures 2, 5, and 7, the light-emitting element 3 is disposed within the lamp holder 1 and faces the light shield 2. Specifically, the light-emitting element 3 is an LED substrate with multiple LEDs, serving as the light source for the refrigerator lighting device 10 of the present invention. The light-emitting element 3 is first engaged with the upper hooks 12, and then slightly pressed along the lower hooks 13 to cause elastic deformation and rebound, thus allowing the light-emitting element 3 to be engaged and positioned by the upper hooks 12 and the lower hooks 13. The lampshade 4 is made of a matte material. One side of the lampshade 4 has a joint edge 41 that can engage with the first inner hooks 23 and the frame 21, and the other side forms four joint hooks 42 that can engage with the second long side 212. The number of joint hooks 42 is not limited to this embodiment; other embodiments may also have other numbers, as long as there is at least one. By placing the light-emitting element 3 inside the lamp holder 1 and facing the light shield 2, the light-emitting element 3 does not emit light directly outward toward the light shield 4. Instead, it is first reflected by the light shield 2 into the lamp holder 1 and then emitted outward through the frosted material of the light shield 4 via scattering. This improves the illumination uniformity of the refrigerator lighting device 10 and increases the average illuminance inside the refrigerator. It should be noted that in this embodiment, the refrigerator lighting device 10 is applied to the refrigerator compartment, but it is not limited thereto. The refrigerator lighting device 10 can also be applied to the vegetable compartment or the freezer.

[0020] In summary, the refrigerator lighting device 10 of the present invention uses the light-emitting element 3 disposed in the lamp holder 1 and facing the light shield 2. The light-emitting element 3 does not directly emit light outward toward the light shield 4, but is first reflected into the lamp holder 1 by the light shield 2 and then emitted outward from the light shield 4 by scattering. This can improve the lighting uniformity of the refrigerator lighting device 10 of the present invention and increase the average illuminance inside the refrigerator. Therefore, it can indeed achieve the purpose of the present invention.

[0021] However, the above description is only an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification shall still fall within the scope of the patent of the present invention.
