Description

Technical Field

[0001] This utility model belongs to the field of buried light technology, specifically relating to a buried light with a novel light guide component. Background Technology

[0002] In-ground lights are lighting fixtures buried in the ground for illumination. They are characterized by their small size, low power consumption, and long lifespan, and are widely used in restaurants, gardens, shopping malls, and tourist attractions. A typical in-ground light consists of a lamp holder, a glass cover, a face ring, and a lamp panel. The upper surface of the lamp panel contains LEDs. When illuminating, the light from the LEDs shines vertically through the glass cover, as shown in CN202122370915.X. While this design can meet general usage needs, the vertical illumination of the LEDs can be glaring, and its anti-glare performance and heat dissipation are limited, thus affecting its lifespan and limiting its applicability.

[0004] The technical solution to achieve the purpose of this utility model is an in-ground lamp with a novel light guide, including a heat sink, a glass light-transmitting plate and a face ring. The heat sink has a cavity with an opening on the top surface, and a light source base is fixed in the cavity by screws.

[0005] The light source holder is provided with a light source cavity with a top opening and a right-angled trapezoidal vertical cross section, wherein the top width of the right-angled trapezoidal light source cavity is greater than the bottom width;

[0006] A light source plate is fixed on the vertical surface of the right-angled trapezoidal light source cavity, and a light guide is provided inside the right-angled trapezoidal light source cavity. A light source hole is provided on the side of the light guide.

[0007] The top surface of the light guide is an inclined surface, and the upper part of the side where the lamp bead hole is located is provided with an arc-shaped surface along the edge of the top surface of the light guide.

[0008] The glass light-transmitting plate is located on the top surface of the radiator and is positioned by clamping with a face ring;

[0009] The light from the light source plate is guided by the light guide, and the edge light is reflected by the inclined side of the right-angled trapezoidal light source cavity. The light shines outward from the top surface of the light guide through the glass light-transmitting plate.

[0010] A further preferred embodiment is that a light-shielding plate is provided on the top surface of the glass light-transmitting plate and the light source base, and a strip lighting channel is provided on the light-shielding plate;

[0011] The inclined surface of the light guide is located within the strip lighting channel.

[0012] A further preferred embodiment is that the width of the inclined surface of the light guide is smaller than the width of the strip-shaped irradiation channel;

[0013] The arc-shaped surface of the light guide is located below the edge of the strip-shaped illumination channel.

[0014] A further preferred embodiment is that the upper part of the outer wall of the radiator is provided with an external thread, and the inner wall of the face ring is provided with an internal thread;

[0015] The face ring is threadedly connected to the heat sink.

[0016] A further preferred embodiment is that mounting springs are fixed on the symmetrical sides of the radiator;

[0017] The radiator is positioned inside the in-ground light housing by means of a snap ring.

[0018] A further preferred embodiment is that the light source board is a light source board containing a plurality of LED beads or a COB light source board.

A light source plate is fixed on the vertical surface of a right-angled trapezoidal light source cavity. A light guide is installed inside the cavity. Light from the light source plate is guided by the light guide, and edge light is reflected by the inclined edge of the cavity. The light then shines outward from the top surface of the light guide through a glass light-transmitting plate. Because the light source plate is located on the vertical surface of the cavity, it does not shine directly outward, thus improving anti-glare performance. Furthermore, the light from the light source plate, after passing through the light guide, ensures stable and effective illumination. Additionally, a recessed cavity within the heat sink improves the overall heat dissipation performance, extending the lifespan of the light source plate. Finally, the overall design is aesthetically pleasing and highly adaptable. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] See Figures 1 to 4 As shown, an in-ground light with a novel light guide includes a heat sink 1, a glass light-transmitting plate 2, and a face ring 3. The heat sink has a recessed cavity 4 with an opening on its top surface, and a light source holder 5 is fixed inside the cavity by screws. In this embodiment, the heat sink, glass light-transmitting plate, and face ring are all conventional structures of the prior art. Furthermore, the upper part of the outer wall of the heat sink has an external thread 6, and the inner wall of the face ring has an internal thread 7. The face ring is threadedly connected to the heat sink. To improve waterproofing, a sealant layer or a sealing gasket layer is provided at the connection between the glass light-transmitting plate and the face ring. The light source holder is a plastic or aluminum structural component, and it has a vertically arranged power cord, which is common technical knowledge. The height of the light source holder is less than the depth of the recessed cavity.

[0031] In this embodiment, the light source base is provided with a light source cavity 8 with a top opening and a right-angled trapezoidal cross-section. The top width of the right-angled trapezoidal light source cavity is greater than the bottom width. Through the above structure, the effectiveness of outward illumination can be guaranteed. At the same time, a light source plate 9 is fixed on the vertical surface of the right-angled trapezoidal light source cavity. A light guide 10 is provided inside the right-angled trapezoidal light source cavity, and a light source hole 11 is provided on the side of the light guide. The light guide is a light guide made of conventional materials, such as light guide plastic structural parts, light guide silicone structural parts, etc. The light source hole is mainly used for the light source chip on the light source plate to be inserted. The shape of the light guide is similar to the shape of the right-angled trapezoidal light source cavity, so that the light guide can be seamlessly connected inside the right-angled trapezoidal light source cavity. In order to facilitate the installation of the light source plate, there are light source plate slots on the symmetrical inner wall of the right-angled trapezoidal light source cavity, which is a common structure.

[0032] In this embodiment, the top surface of the light guide is an inclined surface 12 with an inclination angle of 0-10 degrees, and an arc-shaped surface 13 is provided on the upper part of the side where the lamp bead hole is located, along the edge of the top surface of the light guide. During assembly, the glass light-transmitting plate is positioned on the top surface of the heat sink and held in place by a face ring. The light from the light source plate is guided by the light guide, and the edge light is reflected by the inclined edge of the right-angled trapezoidal light source cavity. The light shines outward from the top surface of the light guide through the glass light-transmitting plate. With the above structure, the light from the light source plate can be prevented from shining outward, which is beneficial to improving the anti-glare performance. Moreover, the illumination range can be guaranteed by the light guide and the right-angled trapezoidal light source cavity.

[0033] In this embodiment, a light-shielding plate 14 is provided on the top surface of the glass light-transmitting plate and the light source base, and a strip lighting channel 15 is provided on the light-shielding plate; the inclined surface of the light guide is located within the strip lighting channel. The width of the inclined surface of the light guide is smaller than the width of the strip lighting channel; the arc-shaped surface of the light guide is located below the edge of the strip lighting channel. Through the above structure, that is, part of the light source on the arc-shaped surface also shines outward through the strip lighting channel, the illumination range can be improved.

[0034] In this embodiment, mounting springs 16 are fixed on the symmetrical sides of the heat sink; the heat sink is positioned inside the in-ground light housing 17 by the mounting springs. The in-ground light housing is a common structure in the prior art, and the mounting springs are also a conventional structure, so they are not described in detail.

[0035] In this embodiment, the light source board is a light source board with a plurality of LED beads.

[0036] This utility model has the following positive effects: Its structure is rationally designed. A light source plate is fixed on the vertical surface of a right-angled trapezoidal light source cavity. A light guide is installed inside the cavity. Light from the light source plate is guided by the light guide, and edge light is reflected by the inclined edge of the cavity. The light then shines outward from the top surface of the light guide through a glass light-transmitting plate. Because the light source plate is located on the vertical surface of the cavity, it does not shine directly outward, thus improving anti-glare performance. Furthermore, the light from the light source plate, after passing through the light guide, ensures stable and effective illumination. Additionally, a recessed cavity within the heat sink improves the overall heat dissipation performance, extending the lifespan of the light source plate. Finally, the overall design is aesthetically pleasing and highly adaptable.

[0037] Example 2

[0038] See Figure 5 As shown, this embodiment is basically the same as embodiment 1, except that the light source board is a COB light source board.

[0039] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
