[0032] For the purposes of the present invention, a more complete description of the application will be presented in the following detailed description. The detailed description is presented with reference to the accompanying drawings. The drawings are presented to illustrate preferred embodiments of the application and are not intended to limit the present application. Rather, the intention is to convey the disclosure of the present application to those skilled in the art. Numerous specific details are described to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without these specific details. In other instances, well-known methods have not been described in detail in order to avoid obscuring the present application.

[0033] It is to be understood that where the terms "fixed" or "attached" are used herein, they are to be interpreted broadly to include direct attachment of one element to another element as well as attachment of one element to another element via an intervening element. As used herein, the terms "vertical", "horizontal", "left", "right", and similar terms are used for purposes of illustration and description only and are not intended to limit the scope of the present application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] Previous downhole lighting fixtures only provide lighting function, and downhole workers cannot feel the change of sunlight on the ground. In 2002, David Berson of Brown University in the United States and others discovered the third type of photoreceptor cells in mammalian retina, i.e. intrinsic photosensitive retinal ganglion cells (ipRGC), which can participate in regulating many non-visual biological effects of human body, including: changes in human life characteristics, hormone secretion and excitement level. With in-depth research of lighting science, medicine and biology, it is revealed that light can penetrate to stimulate the secretion of melatonin to produce the effect of regulating human biological rhythm, so that the lighting environment that meets human health can be created by controlling lighting parameters and lighting environment, and the negative emotions of people can be intervened and some disease conditions can be improved by specially designed lighting environment.

[0036] With the emergence and development of LED lighting technology in recent years, precise control of the lighting spectrum can now be achieved, and the underground sunlight lamp can simulate the spectral changes of the sun at different time periods through intelligent power supply to adjust the output current, so that the workers hundreds of meters underground can feel the sunrise and sunset synchronously, and the human body rhythm is not damaged. The underground sunlight lamp spectrum covers 380-780nm, the 380-450nm band light can inhibit the growth of bacteria, and the 620-780nm band line is the most penetrating radiation line in all sunlight, which has a wide range of health effects on the human body, including: pain relief, muscle tension relief, improved circulation, skin beautification, enhanced immune system function and blood pressure reduction, etc.

[0037] For example, the working mode of the underground sunlight lamp of the present application is: the light emitted during 6:00-6:30 has a color temperature of 2700K; the light emitted during 6:30-7:00 has a color temperature of 3000K; the light emitted during 7:00-8:00 has a color temperature of 4000K; the light emitted during 8:00-9:00 has a color temperature of 4500K; the light emitted during 9:00-10:00 has a color temperature of 5000K; the light emitted during 10:00-15:00 has a color temperature of 5700K; the light emitted during 15:00-16:00 has a color temperature of 5000K; the light emitted during 16:00-17:00 has a color temperature of 4000K; the light emitted during 17:00-18:00 has a color temperature of 3000K; the light emitted during 18:00-6:00 has a color temperature of 5700K. Wherein, K is the color temperature unit (kelvin).

[0038] The main structure of the underground sunlight lamp 10 of the present application is as follows: as shown in Figure 1 , Figure 2 and Figure 3 , it comprises: a die-casting lamp body 100, an LED light-emitting plate 200, an explosion-proof lampshade 300, an intelligent constant-current power supply 400 and a protective rear cover 500. The LED light-emitting plate 200 is arranged on the die-casting lamp body 100, and the explosion-proof lampshade 300 covers the LED light-emitting plate 200, the die-casting lamp body 100 is provided with a receiving groove 110, the intelligent constant-current power supply 400 is received in the receiving groove 110, the intelligent constant-current power supply 400 is electrically connected with the LED light-emitting plate 200, the protective rear cover 500 covers the receiving groove 110, and the protective rear cover 500 and the die-casting lamp body 100 are connected through a protective bolt 600.

[0039] Among them, the protective rear cover 500 is provided with an inspection window 510 (as shown in Figure 4 ) penetrating through the receiving groove 110, and the protective rear cover 500 is provided with a wiring inspection cover 520, which covers the inspection window 510.

[0040] After assembly, the wiring maintenance cover 520 of the protective back cover 500 is at the wiring position of the intelligent constant current power supply 400, and other areas in the accommodating groove 110 are covered and shielded by the protective back cover 500. When the user needs to perform simple detection and maintenance, the user only needs to remove the wiring maintenance cover 520 from the protective back cover 500, and the wiring maintenance cover 520 is exposed, so that the user can perform simple maintenance on the wiring area through the wiring maintenance cover 520. The protective bolt 600 of the present application has a certain anti-disassembly function, which can effectively prevent the user from disassembling it privately. In this way, the user's self-maintenance range is limited, which not only meets the user's needs, but also protects the important parts of the sun lamp 10.

[0041] In the present embodiment, the wiring maintenance cover 520 and the protective back cover 500 are connected through auxiliary bolts 521 (as shown in Figure 4 The auxiliary bolt 521 is a common standard part of the prior art, such as a cylindrical hexagonal bolt. In this way, the user can use conventional tools to disassemble the auxiliary bolt 521, thereby disassembling the wiring maintenance cover 520. Of course, in other embodiments, the wiring maintenance cover 520 and the protective back cover 500 can also be connected through a buckle structure cooperation, and the cooperation of the buckle structure can make the disassembly of the wiring maintenance cover 520 more convenient.

[0042] According to the actual needs and applications of the anti-disassembly function of the protective back cover 500, the present application designs the following several embodiments for the protective bolt 600.

[0043] Embodiment one:

[0044] As shown in Figure 5 , the protective bolt 600 is provided with a special-shaped hole 610, and the protective back cover 500 is connected with the die-casting lamp body 100 through the protective bolt 600. The special-shaped hole 610 of the protective bolt 600 needs to be disassembled using a matching professional tool 601, and the user does not have the professional tool 601, so that the protective back cover 500 has the anti-disassembly function.

[0045] Embodiment two:

[0046] As shown in Figure 6 , the protective bolt 600 includes a protective film 602, and the protective film 602 is pasted on the protective back cover 500 and covers the protective bolt 600; the protective bolt 600 can be selected from common standard bolts. When the user is ready to disassemble the protective bolt 600, the protective film 602 needs to be torn off, which will damage the protective film 602. After returning to the factory, the manufacturer can know that the user has implemented the non-standard disassembly operation when the protective film 602 is found to be damaged.

[0047] In this embodiment, the protective bolt 600 is not completely prohibited from being disassembled by the user. If necessary, the user can directly remove the anti-tamper film 602, and the anti-tamper film 602 will not have a substantial impact on the disassembly of the protective bolt 600.

[0048] Furthermore, Embodiment Two still has significant drawbacks. For example, the tamper-evident film 602 may not be significantly damaged during the removal process, and the user may be able to re-apply a relatively intact tamper-evident film 602 after disassembly, thus rendering the protective bolt 600 meaningless in its anti-disassembly function. Therefore, Embodiment Three was designed in this invention, and the structure of the protective bolt 600 was specifically improved.

[0049] Example 3:

[0050] like Figure 7 As shown, the protective bolt 600 is provided with a bolt head 620 and multiple elastic plates 630, and the die-cast lamp body 100 is provided with a screw hole 120 that mates with the protective bolt 600.

[0051] The screw hole 120 has a threaded area 121 and a locking groove 122 on its inner wall. The elastic sheet 630 includes a smooth part 631, a threaded part 632, and a locking part 633. The smooth part 631 connects to the bolt head 632, the threaded part 632 connects the smooth part 631 and the locking part 633, the threaded part 632 mates with the threaded area 121, and the locking part 633 mates with the locking groove 122. The locking part 633 has a protrusion 633a, and a foldable groove 603 is formed between the threaded part 632 and the locking part 633. Preferably, the end of the locking part 633 also has a guiding inclined surface 633b.

[0052] The working principle of the protective bolt 600 in this embodiment is as follows:

[0053] During assembly before leaving the factory, workers press the protective bolt 600 into the screw hole 120. During this process, the elastic plate 630 of the protective bolt 600 preferentially enters the screw hole 120, and the protrusion 633a of the locking part 633 abuts against the inner wall of the screw hole 120, causing the elastic plate 630 to undergo elastic deformation (tilting and swaying). At this time, the threaded part 632 does not contact the threaded area 121; simultaneously, guided by the guide inclined surface 633b, the elastic plate 630 can smoothly slide into the screw hole 120. After the protective bolt 600 is inserted into place, the locking part 633 is in the locking groove 122, and the protrusion 633a sinks into the locking groove 122 and abuts against the groove wall. At this time, the elastic plate 630 returns to its original position under its own elastic force, and the threaded part 632 and the threaded area 121 fit together (threaded engagement). In this way, the protective bolt 600 cannot be pulled out of the screw hole 120, and the protective bolt 600 connects the protective back cover 500 to the die-cast lamp body 100 (e.g.,Figure 8 as shown;

[0054] When in use, if the user wants to dismount the protective back cover 500, the user needs to take out the protective bolt 600 from the threaded hole 120. At this time, the user needs to rotate the protective bolt 600, and through the thread cooperation between the threaded part 632 and the threaded area 121, the protective bolt 600 is withdrawn from the threaded hole 120. However, due to the clamping of the protrusion 633a and the slot wall of the clamping groove 122, when the protective bolt 600 is rotated, the interaction force between the protrusion 633a and the clamping groove 122 will increase until the elastic sheet 630 is damaged (as shown in Figure 9 and Figure 10 shown). And because the easy-broken groove 603 is arranged, when damaged, the clamping part 633 will be bent (or broken) along the easy-broken groove 603 relative to the threaded part 632. In this way, although the protective bolt 600 can be dismounted, its structure has been irreversibly damaged, so it can be proved that the protective back cover 500 has been dismounted;

[0055] After the protective back cover 500 is dismounted, the user can still use the protective bolt 600 to fix it to the die-casting lamp body 100. However, because the clamping part 633 has been bent (as shown in Figure 10 shown), at this time the protective bolt 600 cannot be installed into the threaded hole 120 by pressing. The user needs to install the protective bolt 600 into the threaded hole 120 by rotating it through the cooperation between the threaded part 632 and the threaded area 121, and then realize the connection between the protective back cover 500 and the die-casting lamp body 100.

[0056] It should be noted that in the embodiment, the bolt head 620 is a transparent structure, and the inner side of the clamping part 633 is provided with a reflective coating. When the factory receives the returned lamps, it can directly observe whether the elastic sheet 630 is damaged through the transparent bolt head 620, and then know whether the protective back cover 500 has been dismounted non-standardly. And because the clamping part 633 is bent along the easy-broken groove 603, the arrangement of the reflective coating makes the clamping part 633 better reflect the light irradiated from the bolt head 620, so that the staff of the factory can more intuitively and clearly judge the state of the clamping part 633. Of course, the inner side of the clamping part 633 can also be painted with bright colors such as red and orange to help the staff to observe.

[0057] In other embodiments, the bolt head 620 can also be provided with a driving through hole 604 (as shown in Figure 7That is to say, the hole on the bolt head 620 for driving the protective bolt 600 is provided in a through-hole structure. In this way, the driving through-hole 604 can retain the original function of driving the protective bolt 600 and also has the function of an observation window. The staff can observe whether the elastic sheet 630 is damaged through the driving through-hole 604. In this way, the bolt head 620 does not need to be transparent and the observation can be achieved.

[0058] It can be seen that the protective bolt 600 has the following characteristics in the above-mentioned embodiment three:

[0059] 1. Convenient and fast assembly. Before leaving the factory, the staff does not need to twist the bolt as in the traditional way, but only needs to press the protective bolt 600 into the threaded hole 120. After being pressed into place, the protective bolt 600 is clamped in the threaded hole 120 and cannot be pulled out.

[0060] 2. The elastic sheet 630 of the protective bolt 600 will be damaged when disassembled. When disassembled, the clamping portion 633 must be bent, and the protective bolt 600 can be pulled out of the threaded hole 120. This makes the protective bolt 600 leave obvious traces after being disassembled, so that the manufacturer can judge whether the protective cover 500 is disassembled non-standardly.

[0061] 3. The disassembled protective bolt 600 does not affect the reuse. Although the clamping portion 633 is bent during the first disassembly, the user can still use the protective bolt 600 as a normal bolt. This allows the user to disassemble and assemble the protective bolt 600 when necessary.

[0062] In other embodiments, the explosion-proof lamp cover 300 and the die-cast lamp body 100 can also be connected by the protective bolt 600. Its function is also to prevent the user from disassembling the explosion-proof lamp cover 300 non-standardly. Preferably, a sealing ring (not shown in the figure) is arranged between the explosion-proof lamp cover 300 and the die-cast lamp body 100. The sealing ring is of a rubber structure. The sealing ring can improve the air tightness of the sun lamp 10, thereby achieving the effect of dust and moisture prevention.

[0063] In one of the embodiments, as shown in Figure 2 and Figure 3 A rotatable hanging bracket 130 is arranged on the die-cast lamp body 100. The user can hang the sun lamp 10 through the hanging bracket 130 and adjust the relative position of the rotatable hanging bracket 130 and the die-cast lamp body 100 to change the illumination angle of the sun lamp 10. In addition, a detachable anti-collision mesh cover 310 is arranged on the outside of the explosion-proof lamp cover 300. The anti-collision mesh cover 310 can protect the explosion-proof lamp cover 300 when a collision occurs, thereby avoiding scratching and damaging the explosion-proof lamp cover 300 and affecting the light transmission.

[0064] In summary, the underground sun lamp 10 can meet the needs of users to carry out simple maintenance or detection, and can protect important components from being disassembled by users in a non-standard manner.

[0065] The above-described embodiments only express several embodiments of the present application, which are described in a more specific and detailed manner, but should not be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which are all within the scope of protection of the present application. Therefore, the scope of protection of the present application should be subject to the appended claims.
