[0031] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.
[0032] An embodiment of the present utility model provides an anti-glare buried lamp 100.
[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In an embodiment of the present utility model, the anti-glare buried lamp 100 includes a first anti-glare member 110, a second anti-glare member 120, and an LED light-emitting member 130 stacked in sequence;
[0034] The LED light-emitting member 130 has at least one LED lamp bead 131;
[0035] The second anti-glare member 120 is configured with stepped holes 120a corresponding to the number of the LED lamp beads 131, and each of the stepped holes 120a can individually avoid the LED lamp beads 131;
[0036] The first anti-glare member is a light-transmitting member, and a concavo-convex structure 112 is provided on the side of the first anti-glare member 110 close to the LED lamp beads 131.
[0037] It can be understood that in the technical solution of the present utility model, by providing a second anti-glare member, the stepped holes 120a on the second anti-glare member can make the light emitted by the LED lamp beads 131 be emitted after multiple reflections and refractions through the stepped holes 120a, effectively dispersing the light. Additionally, the stepped holes 120a can avoid the direct light of the LED lamp beads 131, ensuring the brightness of the light. A part of the light is scattered through the sides or other angles of the stepped holes 120a, reducing the concentration and directivity of the light of the LED lamp beads 131, reducing the glare for the human eye, and at the same time making the lighting range wider and more uniform. Further, although the setting of the second glare member can weaken the glare effect to a certain extent, when the human eye directly looks at the above-mentioned anti-glare buried lamp 100, due to the stepped holes 120a avoiding the direct light of the LED lamp beads 131, the human eye will still feel an obvious glare effect. The technical solution of the present application also provides a first anti-glare member 110, the first anti-glare member 110 is a light-transmitting member, and a concavo-convex structure 112 is provided on the side of the first anti-glare member 110 close to the LED lamp beads 131. When the direct light of the LED lamp beads 131 irradiates on the concavo-convex structure 112, the light is scattered, reducing the intensity of the direct light, thereby further reducing the glare effect of the anti-glare buried lamp 100.
[0038] As Figure 4 shown, optionally, the concavo-convex structure 112 is an annular concavo-convex structure 112. It can be understood that when the concavo-convex structure 112 is an annular concavo-convex structure 112, the light can be distributed more evenly, the light becomes softer, and the comfort of the human vision is further improved.
[0039] Further, as Figure 5 shown, the cross-section of the annular concavo-convex structure 112 is a curve with equal amplitudes. It can be understood that when the cross-section of the annular concavo-convex structure 112 is a curve with equal amplitudes, the trough of the annular concavo-convex structure 112 can contact the upper surface of the second anti-glare member, thereby improving the assembly stability of the anti-glare buried lamp.
[0040] Optionally, the lower edge line of the cross-section of the annular concavo-convex structure 112 is a function curve that changes periodically. Such as a trigonometric function curve or a periodic piecewise function curve. To further improve the visual experience of the anti-glare buried lamp.
[0041] It should also be noted that the above-mentioned concavo-convex structure 112 can be a microscopic structure or a structure that can be clearly observed or touched.
[0042] Optionally, when the concavo-convex structure 112 is a microscopic structure, the first anti-glare member can be the concavo-convex structure 112 obtained by surface sandblasting, or can also be a microscopic structure obtained by surface etching.
[0043] Preferably, when the concave-convex structure 112 is a structure that can be clearly observed or touched, in order to avoid serious attenuation of the light intensity caused by the concave-convex structure 112, the concave-convex structure 112 is an annular concave-convex structure 112. While the annular concave-convex structure 112 can soften the light, most of the light passes through the concave part of the annular concave-convex structure 112 to penetrate the first anti-glare member 110 for illumination.
[0044] Optionally, the convex part of the annular concave-convex structure 112 is correspondingly arranged above the LED lamp bead 131 to enhance the light scattering effect.
[0045] Optionally, the second anti-glare member is also a light-transmitting member.
[0046] Please refer to Figure 1 、 Figure 2 and Figure 6 , in another embodiment of the present invention, the anti-glare buried lamp 100 further includes a buried housing 140 and a fixing ring 150;
[0047] The first anti-glare member 110, the second anti-glare member 120, and the LED lighting member 130 are all arranged inside the buried housing 140. The fixing ring 150 is in contact with the first anti-glare member through a waterproof rubber strip; the fixing ring 150 is fixedly connected to the buried housing 140 by screws.
[0048] It can be understood that the fixing ring 150 is provided to fix the first anti-glare member 110 and the second anti-glare member. The fixing ring 150 is in contact with the first anti-glare member through a waterproof rubber strip to achieve the waterproof seal of the anti-glare buried lamp.
[0049] Furthermore, please refer to Figure 2 and Figure 6 , the anti-glare buried lamp 100 further includes a bottom shell 160 for sealing the buried housing 140 and a driver 170 for controlling the LED lighting member 130;
[0050] The driver 170 is installed in the buried housing 140. The inside of the bottom shell 160 can be attached to the driver 170, and a metal heat dissipation structure 180 is attached to the outside of the bottom shell 160.
[0051] It can be understood that the separate arrangement of the driver 170 and the LED lighting member 130 can improve the heat dissipation performance inside the buried housing 140. And when the concave-convex structure 112 of the first anti-glare member 110 is set as an annular concave-convex structure 112, the inner surface area of the first anti-glare member 110 is increased and the thickness of the concave part of the annular concave-convex structure 112 is relatively thin, which can significantly improve the heat dissipation performance of the LED lighting member.
[0052] Optionally, the metal heat dissipation structure 180 may be metal heat dissipation fins and may be a liquid cooling device such as a liquid cooling pack or the like.
[0053] Please continue to refer to Figure 2 and Figure 6 , in a preferred embodiment, barbs 161 are further provided on the outer periphery of the bottom case 160. One end of the barb 161 is connected to the bottom case 160, and the other end of the barb 161 is arranged to expand and faces the buried housing 140.
[0054] Furthermore, the bottom case 160 is rotationally snap-connected to the buried housing 140.
[0055] Optionally, a sealing member is further provided between the bottom case 160 and the buried housing 140.
[0056] In the technical solution of the above embodiment, it can be understood that the setting of the barb 161 is mainly to improve the installation stability of the anti-glare buried lamp and the convenience during the maintenance of the anti-glare buried lamp. Specifically, when installing the anti-glare buried lamp on the ground, the bottom case 160 and the buried housing 140 can be connected together, and then the bottom case 160 and the buried housing 140 are installed into the hole positions on the ground. During the installation process, the barb 161 provided on the bottom case 160 is deformed, and the barb 161 abuts against the inner wall of the hole position on the ground, thereby fixing the anti-glare buried lamp 100.
[0057] When the buried lamp needs to be maintained, the staff only needs to rotate the buried housing 140 within a certain angle range to separate the buried housing 140 from the bottom case 160 for maintenance.
[0058] The above is the description. The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
