Description

Technical Field

[0001] The present invention relates to the field of smart lighting technology, and in particular to a smart lighting device for a water environment. Background Art

[0002] A buried lamp is a lamp specially designed to be installed below the ground or flush with the ground. This lamp is usually used in outdoor environments such as parks, walkways, gardens, squares, etc. to provide lighting or decorative effects. A fountain buried lamp is a lamp specially designed for a fountain environment to illuminate the fountain's water column, pool or surrounding decorative elements. This type of lamp needs to have special protective properties to cope with water, humidity and possible chemicals in the fountain environment. Most of the existing fountain buried lamps are sealed with sealing rings, but the sealing rings are very prone to aging and deformation after long-term use, resulting in reduced sealing effect. At the same time, fountain buried lamps often need to operate at high loads because they need to cooperate with fountain performances. At this time, the electronic components inside the fountain buried lamps will generate heat, causing the gas inside the buried lamp to expand due to heat, and then the pressure will increase. Changes in pressure and temperature can easily accelerate the aging of the electronic components inside the buried lamp and reduce the service life of the buried lamp. Summary of the invention

[0015] 2. By accumulating elastic force in the elastic part during installation, the elastic part drives the device to protrude from the ground when the device is disassembled, so that the fixing plate is separated from the ground and a gap is formed between the fixing plate and the ground, which is convenient for workers to take and improve replacement efficiency.

DETAILED DESCRIPTION

[0026] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] Most of the existing fountain underground lamps are sealed with sealing rings. However, the sealing rings are prone to aging and deformation after long-term use, resulting in a decrease in the sealing effect. In addition, the fountain underground lamps need to run at high load when cooperating with fountain performances, which will cause the internal electronic components to generate heat, causing the gas inside the lamp to expand due to the heat and increase the pressure. This repeated pressure and temperature changes will accelerate the aging of the internal electronic components, thereby shortening the service life of the underground lamp.

[0028] Embodiment 1: A smart lighting device for a water environment, such as Figure 1-Figure 4 As shown, it includes a lighting body 1, a lampshade 2 is detachably connected to the top of the lighting body 1, the lampshade 2 is coaxially spliced ​​with the lighting body 1 (splicing means mutual installation between parts), a fixing plate 3 is detachably connected to the upper plane of the lampshade 2, the lampshade 2 is spliced ​​with the fixing plate 3, four bolts in an annular array are threadedly connected to the fixing plate 3, and when the device is put into use, the four bolts are rotated to fix the device on the ground (this process is the assembly process of the device), an annular groove is arranged on the upper plane of the lighting body 1, and evenly distributed lighting elements 4 are arranged inside the lighting body 1, the lampshade 2 divides the annular groove on the lighting body 1 into two inner and outer cavities, the lighting body 1 and the lampshade 2 cooperate to form a cavity connected to the inner cavity, the evenly distributed lighting elements 4 are located in the cavity, and a through hole in an annular array is arranged at the bottom of the lampshade 2, and the through holes in the annular array are used The two cavities are connected to form a communicating vessel feature between the inner and outer cavities. The annular groove on the plane of the lighting body 1 is filled with a sealing liquid 5. The density of the sealing liquid 5 is greater than the density of water, and the sealing liquid 5 is not miscible with water, such as mineral oil and silicone oil. After the lighting body 1 and the lampshade 2 are spliced, the liquid level of the sealing liquid 5 is higher than the height of the through holes in the annular array, so as to prevent external water vapor from entering the cavity formed by the lighting body 1 and the lampshade 2. The liquid seal of the sealing liquid 5 blocks external water vapor from entering the cavity formed by the lighting body and the lampshade, thereby improving the sealing effect. When the gas pressure in the device changes, the liquid level change based on the communicating vessel principle enables the sealing liquid 5 to adapt to the pressure change of the gas in the cavity formed by the lighting body 1 and the lampshade 2, thereby avoiding the pressure and temperature changes of the gas in the cavity formed by the lighting body 1 and the lampshade 2, which accelerate the aging of internal components.

[0029] The staff installs several devices according to the trajectory of the fountain's nozzles. During installation, the staff places the device in a pre-reserved drill hole, and then fixes the device to the ground with bolts. At this time, the installation of the device is completed. When performing a fountain show at night, the staff turns on the device in an orderly manner in conjunction with the fountain, so that the light emitted by the lighting element 4 illuminates the fountain and presents a strong visual effect.

[0030] After the device is assembled on the ground and put into use, the present invention uses the sealing liquid 5 to seal the lighting body 1 to prevent external water vapor from entering the device, and blocks the water vapor on the liquid surface of the sealing liquid 5 in the outer cavity to avoid water mist inside the lampshade 2 to affect the lighting effect of the device. At the same time, the sealing liquid 5 can absorb the heat generated when the device is running, improve the heat dissipation rate of the device, and the through holes in the annular array at the bottom of the lighting body 1 and the lampshade 2 form a communicating vessel feature. When the device is running at high load, heat is generated, which can easily cause the gas in the cavity formed by the lighting body 1 and the lampshade 2 to be heated, thereby increasing the pressure. At this time, the lighting The gas in the cavity formed by the cooperation of the main body 1 and the lampshade 2 will push the sealing liquid 5 in the inner cavity, so that the sealing liquid 5 in the inner cavity enters the outer cavity along the through holes of the annular array, thereby expanding the spatial volume in the device, so as to adapt to the internal pressure changes, and block the external water vapor through the liquid seal of the sealing liquid 5 to improve the sealing effect, and make the sealing liquid 5 absorb part of the heat in the gas. At the same time, the liquid level changes based on the principle of the communicating vessel are adaptive to the pressure changes of the gas in the cavity formed by the cooperation of the lighting main body 1 and the lampshade 2, so as to avoid the changes in the pressure and temperature of the cavity gas formed by the cooperation of the lighting main body 1 and the lampshade 2 to accelerate the aging of internal components.

[0031] Embodiment 2: Based on embodiment 1, Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the outer side surface of the annular groove of the lighting body 1 is fixedly connected with a first fixing ring 201, and the outer wall of the lampshade 2 is fixedly connected with a second fixing ring 202. The first fixing ring 201 and the second fixing ring 202 are composed of protrusions in a circular ring and an annular array, and the two are staggered. The first fixing ring 201 and the second fixing ring 202 are sealed and matched. When the lighting body 1 and the lampshade 2 are spliced, the protrusions of the first fixing ring 201 and the protrusions on the second fixing ring 202 are keyed to each other until the splicing of the lighting body 1 and the lampshade 2 is completed. At this time, the first fixing ring 201 and the second fixing ring 202 are staggered up and down, and the cavity on the outside is blocked to prevent leakage of the sealing liquid 5. The inner side surface of the annular groove of the lighting body 1 is fixedly connected with a third fixing ring Ring 203, the lampshade 2 is fixedly connected with a fourth fixing ring 204, the third fixing ring 203 and the fourth fixing ring 204 are both composed of convex blocks in a circular ring and annular array, the convex blocks on the two are staggered, and the convex blocks on the third fixing ring 203 are spliced ​​by an arc block located on the upper side and an isosceles triangle block on the lower side, and the vertex angle of the isosceles triangle block faces the lower side, which is convenient for splicing the convex blocks on the third fixing ring 203 with the convex blocks on the fourth fixing ring 204, and the third fixing ring 203 and the fourth fixing ring 204 are sealed and matched, and when the lighting body 1 and the lampshade 2 are spliced, the convex blocks on the third fixing ring 203 and the convex blocks on the fourth fixing ring 204 are bonded to each other, and this is done until the splicing of the lighting body 1 and the lampshade 2 is completed, at which time the arc of the convex blocks on the third fixing ring 203 is The protrusions on the fourth fixing ring 204 are spliced ​​into a cylindrical sealing ring to block the sealing liquid 5 in the inner cavity to prevent the sealing liquid 5 from entering the interior of the device. After the device is assembled to the ground, the fourth fixing ring 204 moves downward so that the protrusions in the annular array on it are misaligned with the arc blocks in the annular array on the third fixing ring 203. At this time, a gap for circulating gas is formed between the protrusions in the annular array of the fourth fixing ring 204 and the adjacent isosceles triangle blocks on the third fixing ring 203. The first fixing ring 201 and the second fixing ring 202 are made of flexible material, and the protrusions between the first fixing ring 201 and the second fixing ring 202 are staggered and bonded. Through the annular staggered bonding of the flexible material, the load of the lampshade 2 is evenly distributed and its stress is dispersed, thereby reducing the parts. Fatigue damage, to avoid damage to the device caused by ground vibration caused by the fountain spraying water, the third fixing ring 203 and the fourth fixing ring 204 are made of hard materials, the third fixing ring 203 and the fourth fixing ring 204 are bonded with the upper arc blocks, the lampshade 2 is rigidly supported in the circumferential direction, and the stability is improved, the first fixing ring 201 and the second fixing ring 202 are provided with ventilation channels 205 in the protrusions of the annular array, and the two adjacent ventilation channels 205 are connected and matched. Before the device is assembled to the ground, the ventilation channels 205 in the protrusions of the first fixing ring 201 and the second fixing ring 202 are not connected to each other, which are used to block the sealing liquid 5 located in the outer cavity. When the device is installed on the ground, the second fixing ring 202 moves downward at this time,The air passages 205 in the protrusions of the first fixing ring 201 and the second fixing ring 202 are connected to each other and communicated to allow gas to circulate. When the device is not in use, the sealing liquid 5 in the annular groove of the lighting body 1 is blocked to prevent the sealing liquid 5 inside from leaking when the device is tipped over, thereby reducing the liquid sealing effect of the device.

[0032] like Figure 1-Figure 5 As shown, the bottom of the lighting body 1 is slidably connected with a lamp holder 301, and the lamp holder 301 is placed at the bottom of the reserved hole. An elastic member 302 is arranged between the lamp holder 301 and the lighting body 1. The elastic member 302 is a spring. The elastic member 302 is used to drive the lighting body 1 to move upward, so that the fixed plate 3 is separated from the ground, which is convenient for the staff to replace the device. The lampshade 2 is located at one end of the annular groove of the lighting body 1 and is fixedly connected with an annular spring 303. The annular spring 303 is provided with an annular array of notches, which is convenient for the annular spring 3 03 is bent, and the annular spring piece 303 is bent toward the outside, so that the annular spring piece 303 forms a conical support for the lampshade 2 after being bent, thereby improving the stability of the lampshade 2. The elastic coefficient of the elastic member 302 is smaller than the elastic coefficient of the annular spring piece 303, so that the elastic member 302 is preferentially compressed to the required degree, and the bottom of the lamp holder 301 is fixedly connected with a plurality of circumferentially distributed limit blocks 304, and the circumferentially distributed limit blocks 304 are all matched with the bottom limit of the lighting body 1 to limit the assembly height of the lighting body 1.

[0033] When the device is installed, the annular spring 303 is in an unbent state, and then the staff starts to turn the bolt to fix the device. As the bolt gradually moves downward, the downward pressure of the bolt drives the fixing plate 3 to move downward, and the fixing plate 3 moves synchronously through the lampshade 2 and the annular spring 303 at the bottom thereof. At this time, the annular spring 303 pushes the lighting body 1 to slide downward along the lamp holder 301 at the bottom, so that the elastic member 302 is gradually compressed, and the annular spring 303 is bent outward at the same time. Since the elastic coefficient of the elastic member 302 is smaller than the elastic coefficient of the annular spring 303, the compression degree of the elastic member 302 is large, until the lighting body 1 contacts with multiple limit blocks 304 distributed circumferentially. At this time, the lighting body 1 cannot continue to move downward, and the fixing plate 3 has not yet completely fit with the ground. At this time, the staff continues to turn the bolt. The lampshade 2 squeezes the annular spring sheet 303 at the bottom to continue to bend outwards, and at the same time, the lampshade 2 drives the second fixing ring 202 and the fourth fixing ring 204 thereon to move downward synchronously, and the second fixing ring 202 slides downward along the first fixing ring 201, so that the annular array of ventilation channels 205 on the second fixing ring 202 is gradually connected with the ventilation channels 205 on the first fixing ring 201, and at the same time, the fourth fixing ring 204 slides downward along the third fixing ring 203, so that a gap is generated between the fourth fixing ring 204 and the third fixing ring 203, thereby releasing the blockage of the sealing liquid 5 in the annular groove of the lighting body 1, and this is carried out until the fixing plate 3 is in contact with the ground, at which time the two adjacent ventilation channels 205 are completely connected, and the installation of the device is completed.

[0034] When the device is damaged after long-term use, the staff needs to replace the device and perform maintenance. At this time, the staff removes the four bolts. Due to the disappearance of the pressure under the bolts, the annular spring 303 begins to reset, and the annular spring 303 pushes the lampshade 2 to move upward synchronously. At this time, the lampshade 2 drives the second fixing ring 202 and the fourth fixing ring 204 to move upward synchronously. The second fixing ring 202 slides along the first fixing ring 201, so that the two adjacent ventilation channels 205 are misaligned. At the same time, the first fixing ring 201 and the second fixing ring 202 cooperate to block all the ventilation channels 205. The fourth fixing ring 204 moves upward and gradually fits with the third fixing ring 203 to block the gap between the two. At this time, the sealing liquid 5 is sealed in the annular groove of the lighting body 1, so that the sealing liquid 5 inside the device is sealed when it is not assembled, to prevent the sealing liquid 5 inside the device from leaking when the device is tipped over, thereby reducing the liquid sealing effect of the device, and the elastic member 302 resets after losing the downward pressure of the lighting body 1, and drives the lighting body 1 to move upward, and the lighting body 1 is separated from the multiple limit blocks 304 distributed circumferentially, and the lighting body 1 drives the fixed disk 3 to move upward synchronously. At this time, the fixed disk 3 is separated from the ground and a gap is formed between the ground, which is convenient for the staff to take and improve the replacement efficiency. Then the staff takes the device out of the drill hole, and the disassembly of the device is completed at this time.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
