Description
Technical Field
[0001] This utility model relates to the field of buried lighting technology, specifically to a buried spotlight structure. Background Technology
[0002] With the increasing demand for urban landscape lighting, in-ground spotlights, as a special type of lighting equipment, have been widely used in various fields such as roads, scenic spots, and building facades due to their advantages such as strong concealment, high luminous efficiency, and wide adaptability.
[0003] However, some existing in-ground lighting systems use halogen lamps. Halogen lamps can reach temperatures of 60-70 degrees Celsius after prolonged use, posing a safety hazard, especially for children. Children, driven by curiosity, often play on the ground and touch objects, making them susceptible to exposure to the high temperatures of the in-ground lights and potential burns. In fact, similar burn incidents involving children have been reported and have drawn widespread attention. Utility Model Content
[0004] This utility model addresses the technical problems existing in the prior art by providing a buried spotlight structure to solve the problem that some existing buried lighting devices use halogen lamps as light sources. After prolonged use, halogen lamps can often reach temperatures of 60-70 degrees Celsius, which poses a safety hazard, especially for children. Children, due to their strong curiosity, often play on the ground and touch surrounding objects, making them susceptible to contact with the high temperature of the buried lamp, potentially leading to burns.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a buried spotlight structure, comprising:
[0006] Preset slots;
[0007] An in-ground light, wherein the in-ground light is installed in a pre-set groove;
[0008] A heat shield, detachable from the outside of a preset slot, wherein the radial dimension of the heat shield is larger than that of the preset slot, and the heat shield is made of a transparent material;
[0009] A support member made of shape memory metal is disposed between a heat shield and the housing of an in-ground light, wherein the support member is bent below its extreme temperature and the heat shield is in contact with the ground around a pre-set groove.
[0010] The beneficial effects of this utility model are:
[0011] 1) This device is equipped with a heat shield on the outside of the in-ground light. The heat shield effectively isolates the in-ground light from the external environment, preventing children from directly contacting the in-ground light while playing. This eliminates the risk of burns caused by touching high-temperature lamps. The protective design of the heat shield improves the safety of the in-ground light, especially in public places, and can effectively prevent accidental burns.
[0012] 2) Secondly, a support component made of shape memory metal is installed at the bottom of the heat shield. This support component bends when the temperature is below its abnormal temperature, allowing the heat shield to contact the ground. Since the radial dimension of the heat shield is larger than the preset groove, it can completely cover and seal the in-ground light, further blocking the influence of the external environment on the in-ground light. This not only effectively prevents children's fingers from penetrating and contacting the in-ground light, but also prevents rainwater from entering the interior of the in-ground light during rain. When the temperature of the in-ground light rises after it starts working and reaches the abnormal temperature of the support component, the support component will return to its original shape. The heat shield moves away from the in-ground light along with the deformation of the support component, forming a certain gap between them. This gap allows external air to flow between the heat shield and the in-ground light, thereby accelerating the heat dissipation of the in-ground light. In summary, this device, through the innovative combination of heat shield design and shape memory metal support component, significantly improves the safety and heat dissipation of in-ground spotlights, effectively solving the problems in the existing technology and providing a safer solution for the widespread application of in-ground lighting equipment.
[0013] On the basis of the above technical solution, the present invention can also be improved as follows.
[0014] Furthermore, the heat shield has a dome shape.
[0015] The beneficial effects of adopting the above-mentioned further solution are that the dome shape design allows rainwater to flow quickly from the surface of the heat shield to the ground, preventing rainwater from accumulating on the heat shield and effectively avoiding corrosion problems that may be caused by water accumulation. It also reduces the potential damage of water to the in-ground lights and other components. Secondly, since the dome shape reduces sharp edges or protrusions, it will not cause obstacles when pedestrians walk by, thereby further improving the safety of the place of use.
[0016] Furthermore, the outer side of the heat shield has several heat dissipation holes arranged in a ring array.
[0017] The beneficial effect of adopting the above-mentioned further solution is that by opening several heat dissipation holes on the outside of the heat protection cover, the air circulation can be effectively increased, the air convection and ventilation inside and outside the heat protection cover can be promoted, thereby accelerating the heat dissipation speed of the in-ground light, helping to reduce the temperature of the in-ground light, and preventing overheating from having an adverse effect on the performance of the lamp.
[0018] Furthermore, the axial direction of each of the heat dissipation holes is inclined close to the ground.
[0019] The beneficial effect of adopting the above-mentioned further solution is that, since the heat dissipation holes are inclined in the axial direction, when rainwater enters the heat dissipation holes, it can still flow out along the inclined direction, avoiding the rainwater from flowing back into the anti-scalding cover. Therefore, even in rainy weather, rainwater will not penetrate into the in-ground light, effectively preventing rainwater erosion.
[0020] Furthermore, a speaker is provided on one side of the preset slot to play the sound of "There is a leakage, please stay away".
[0021] Furthermore, the speaker is electrically connected to the support member.
[0022] The beneficial effect of adopting the above-mentioned further solution is that the support component is installed on the housing of the in-ground light. When the in-ground light experiences a leakage, the current will be conducted through the housing of the in-ground light to the support component. Since the support component is electrically connected to the speaker, the leakage current can activate the speaker and play a warning sound "Leakage has occurred, please stay away". It can issue an alarm in time at the moment the leakage occurs, reminding pedestrians or nearby people to stay away from the leakage area, ensuring the safety of public places, and effectively preventing the injury caused by leakage accidents. Especially in public places or densely populated areas, the safety reminder mechanism greatly improves the safety performance of in-ground spotlights and reduces the potential threat of leakage accidents to people.

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0030] With the increasing demand for urban landscape lighting, in-ground spotlights, as a special type of lighting equipment, have been widely used in various fields such as roads, scenic spots, and building facades due to their advantages such as strong concealment, high luminous efficiency, and wide adaptability.
[0031] However, some existing in-ground lighting devices use halogen lamps as light sources. Halogen lamps can reach temperatures of 60-70 degrees Celsius after prolonged use, posing a safety hazard, especially for children. Children, due to their curiosity, often play on the ground and touch surrounding objects, making them susceptible to contact with the high temperatures of the in-ground lamps, potentially leading to burns. In fact, similar burn incidents involving children have been reported, drawing widespread attention. To address this issue, the inventor has proposed an in-ground spotlight structure.
[0032] The present invention provides the following preferred embodiments.
[0033] like Figures 1-4 As shown, an in-ground spotlight structure includes:
[0034] Preset slot 10, preset slot 10 is opened on the ground;
[0035] The in-ground light 20 is installed in the preset groove 10;
[0036] The heat shield 60 is detachable on the outside of the preset groove 10. The radial dimension of the heat shield 60 is larger than that of the preset groove 10, and the heat shield 60 is made of transparent material (the transparent material is transparent acrylic material or transparent glass).
[0037] A support member 30 made of shape memory metal is disposed between the heat shield 60 and the housing of the in-ground light 20, wherein the support member 30 is bent below its extreme temperature and the heat shield 60 is in contact with the ground around the preset groove 10.
[0038] This device has a heat shield 60 installed on the outside of the in-ground light 20. The heat shield 60 effectively isolates the in-ground light 20 from the external environment, preventing children from directly contacting the in-ground light 20 while playing. This eliminates the risk of burns caused by touching high-temperature lamps. The protective design of the heat shield 60 improves the safety of the in-ground light 20, especially in public places, and can effectively prevent accidental burns.
[0039] Secondly, a support member 30 made of shape memory metal is provided at the bottom of the heat shield 60. This support member 30 bends when the temperature is below its abnormal temperature, allowing the heat shield 60 to contact the ground. Since the radial dimension of the heat shield 60 is larger than the preset groove 10, it can completely cover and seal the in-ground light 20, further blocking the influence of the external environment on the in-ground light 20. This not only effectively prevents children's fingers from penetrating and contacting the in-ground light 20, but also prevents rainwater from entering the interior of the in-ground light 20 during rain. When the temperature of the in-ground light 20 rises after it is working and reaches the abnormal temperature of the support member 30... When the support 30 returns to its original shape, the heat shield 60 moves away from the in-ground light 20 as the support 30 deforms, forming a gap between it and the in-ground light 20. This gap allows external air to flow between the heat shield 60 and the in-ground light 20, thereby accelerating the heat dissipation of the in-ground light 20. In summary, this device, through the innovative design of the heat shield 60 and the combination of the memory metal support 30, significantly improves the safety and heat dissipation of the in-ground spotlight, effectively solves the problems in the existing technology, and provides a safer solution for the widespread application of in-ground lighting equipment.
[0040] In this embodiment, as Figures 1-4 As shown, the heat shield 60 has a dome shape. The dome shape design allows rainwater to flow quickly from the surface of the heat shield 60 to the ground, preventing rainwater from accumulating on the heat shield 60. This effectively avoids corrosion problems that may be caused by water accumulation and also reduces the potential damage of water to the in-ground light 20 and other components. Secondly, since the dome shape reduces sharp edges or protrusions, it will not cause obstacles when pedestrians walk by, thereby further improving the safety of the place of use.
[0041] In this embodiment, as Figures 1-4 As shown, the outer side of the heat shield 60 has several heat dissipation holes 40 arranged in a ring. By opening several heat dissipation holes 40 on the outer side of the heat shield 60, the air circulation can be effectively increased, and the convection and ventilation of the air inside and outside the heat shield 60 can be promoted, thereby accelerating the heat dissipation speed of the in-ground lamp 20, helping to reduce the temperature of the in-ground lamp 20, and preventing overheating from having an adverse effect on the performance of the lamp.
[0042] In this embodiment, as Figures 1-4 As shown, the axial direction of each heat dissipation hole 40 is inclined close to the ground. Because the axial direction of the heat dissipation hole 40 is inclined, when rainwater enters the heat dissipation hole 40, it can still flow out along the inclined direction, avoiding the rainwater flowing back into the anti-scalding cover 60. Therefore, even in rainy weather, rainwater will not penetrate into the buried light 20, effectively avoiding the erosion of rainwater.
[0043] In this embodiment, as Figures 1-4As shown, a speaker 50 is provided on one side of the preset slot 10 to play the sound "Looping current, please stay away". The speaker 50 is electrically connected to the support 30, which is installed on the housing of the in-ground light 20. When the in-ground light 20 experiences an electrical leakage, the current will be conducted through the housing of the in-ground light 20 to the support 30. Since the support 30 is electrically connected to the speaker 50, the leakage current can activate the speaker 50 to play the warning sound "Looping current, please stay away". It can issue an alarm in time at the moment the leakage occurs, reminding pedestrians or nearby people to stay away from the leakage area, ensuring the safety of public places, and effectively preventing the injury caused by leakage accidents. Especially in public places or densely populated areas, the safety reminder mechanism greatly improves the safety performance of the in-ground spotlight and reduces the potential threat of leakage accidents to people.
[0044] The specific working process of this utility model is as follows:
[0045] (1) Anti-scalding measures
[0046] First, a heat shield 60 is installed on the outside of the in-ground light 20. The heat shield 60 effectively isolates the in-ground light 20 from the external environment, preventing children from having direct contact with the in-ground light 20 while playing, and eliminating the risk of burns caused by touching high-temperature lamps.
[0047] (2) Heat dissipation of the in-ground light 20
[0048] A support member 30 made of shape memory metal (which can be, but is not limited to, nickel-titanium alloy) is provided at the bottom of the heat shield 60. The support member 30 bends when the temperature is below its abnormal temperature, allowing the heat shield 60 to contact the ground. Since the radial dimension of the heat shield 60 is larger than the preset groove 10, the heat shield 60 can completely cover and seal the in-ground light 20, further blocking the influence of the external environment on the in-ground light 20. This not only effectively prevents children's fingers from penetrating and contacting the in-ground light 20, but also prevents rainwater from entering the interior of the in-ground light 20 when it rains. When the temperature of the in-ground light 20 rises after it starts working and reaches the abnormal temperature of the support member 30, for example, when it reaches the threshold of about 50 degrees Celsius, the support member 30 will return to its original shape. The heat shield 60 moves away from the in-ground light 20 as the support member 30 deforms, forming a certain gap between the support member 30 and the in-ground light 20. The gap allows external air to flow between the heat shield 60 and the in-ground light 20, thereby accelerating the heat dissipation of the in-ground light 20.
[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
