DETAILED DESCRIPTION

[0030] The utility model will be further described below in connection with the drawings and specific embodiment, but the protection scope of the utility model is not limited to this.

[0031] Example one:

[0032] For example Figures 1 to 7As shown, the utility model is a kind of LED projection lamp with explosion-proof net 1 and support 12.In the drawing, the explosion-proof net 1 is grid structure, completely wraps the opening area of heat dissipation shell 7.The explosion-proof net 1 can prevent larger external objects, such as branches, stones or tools, from falling directly on the heat dissipation shell 7 or tempered glass 2 and affecting the normal operation of the projection lamp, thereby effectively reducing the potential impact and damage to the important components of the projection lamp including the heat dissipation shell 7 and the tempered glass 2.

[0033] At the same time, the support 12 is connected near the lower part of the heat dissipation shell 7, which facilitates the installation of the projection lamp and can improve the stability of the projection lamp after installation, and the connection between the support 12 and the heat dissipation shell 7 can rotate to adjust the illumination angle of the projection lamp or can be fixed to keep the current illumination angle of the projection lamp, which is convenient for users to install and maintain in the future.

[0034] The support 12 and the heat dissipation shell 7 are hinged, which can meet different installation angles and lighting needs, and can easily fix the projection lamp at a certain position through simple operation, ensuring that the projection lamp will not move accidentally during use, thereby ensuring the stability of the lighting.

[0035] The tempered glass 2 is clamped between the explosion-proof net 1 and the heat dissipation shell 7, and the tempered glass 2 and the heat dissipation shell 7 are fixed and installed by the fixing buckle 9. A step is provided inside the heat dissipation shell 7, the step is close to the opening position of the heat dissipation shell 7, and the height difference between the step and the heat dissipation shell 7 is equivalent to the thickness of the tempered glass 2. The tempered glass 2 is placed therein, and the surface of the tempered glass 2 is flush with the opening position of the heat dissipation shell 7. Because the lighting components of the projection lamp are mainly placed below the step of the heat dissipation shell 7, the tempered glass 2 can completely cover the opening of the heat dissipation shell 7 and cover the lighting components of the projection lamp inside the heat dissipation shell 7.

[0036] The tempered glass 2 is installed between the explosion-proof net 1 and the heat dissipation shell 7, which can provide additional protection for the lighting components and other important core functional components of the projection lamp. The tempered glass 2 can block some small and not very impacting but still damaging the heat dissipation shell 7 and the lighting components, which can serve as a supplementary protection after the explosion-proof net 1. The fixed connection between the tempered glass 2 and the heat dissipation shell 7 is realized by the fixing buckle 9.

[0037] The fixing buckle 9 is in U shape, one side of the fixing buckle 9 is buckled on the tempered glass 2, and the other side is matched with the rear side of the heat dissipation shell 7. The heat dissipation shell 7 is provided with a specially matched installation platform of the fixing buckle 9, and the installation platform is arranged on the heat dissipation shell 7. The wall thickness of the heat dissipation shell 7 at the position of the installation platform is much larger than that of the rest of the heat dissipation shell 7 which is not responsible for installation. The highest position of the installation platform is provided with a blind hole, which can cooperate with the fixing buckle bolt 10 to firmly fix the fixing buckle 9 on the heat dissipation shell 7.

[0038] The fixing buckle 9 can limit the movement stroke between the tempered glass 2 and the heat dissipation shell 7. At the same time, it can reduce the collision that may occur between the tempered glass 2 and the heat dissipation shell 7 when shaking, thereby prolonging the service life of the tempered glass 2 and the heat dissipation shell 7. As can be seen from the figure, the side surface of the installation platform matched with the fixing buckle 9 near the outer side shows the horizontal plane, and then becomes an inclined plane, and the end surface of the fixing buckle bolt 10 is a vertical plane. In fact, two vertical side plates with a height slightly higher than the plane where the fixing buckle bolt 10 is arranged are arranged on both sides of the plane where the fixing buckle bolt 10 is arranged, so as to clamp the installation platform in the middle.

[0039] Because one fixing buckle 9 is fixedly installed with the installation platform through one fixing buckle bolt 10. The fixing buckle 9 can rotate relative to the heat dissipation shell 7 after installation, and also facilitates positioning during installation of the fixing buckle 9. Therefore, the positions of the two sides of the fixing buckle 9 are limited and positioned by the side plates arranged on both sides of the installation platform.

[0040] And at the matched position of the heat dissipation shell 7 and the tempered glass 2, a ring-shaped stepped structure is designed inside the heat dissipation shell 7, which utilizes the internal space of the heat dissipation shell 7, so that the overall structure is more compact. The step is close to the opening of the heat dissipation shell 7. The height difference between the step surface and the opening of the heat dissipation shell 7 is equivalent to the thickness of the tempered glass 2. The tempered glass 2 can be completely embedded in the heat dissipation shell 7, and the edges around the tempered glass 2 are placed on the step surface of the step.

[0041] Therefore, the machining precision of the stepped structure inside the heat dissipation shell 7 has certain requirements, otherwise it may cause uneven installation between the tempered glass 2 and the heat dissipation shell 7, which may cause that the tempered glass 2 and the heat dissipation shell 7 matched at some positions cannot be buckled and fixed by the fixing buckle 9, that is, the thickness of the tempered glass 2 and the heat dissipation shell 7 matched together plus the thickness of the installation platform is greater than the thickness of the opening of the fixing buckle 9.

[0042] The surface of the tempered glass 2 is horizontally consistent with the opening edge of the heat dissipation shell 7. In this way, the sealing and safety of the tempered glass 2 and the heat dissipation shell 7 as a whole can be better guaranteed, and the impurities such as dust and moisture from the outside can be prevented from entering the inside of the light projector.

[0043] Since the main lighting components of the light projector are arranged in the space below the step of the heat dissipation shell 7, the tempered glass 2 can better protect these lighting components in normal use. The tempered glass 2 not only completely covers the opening of the heat dissipation shell 7 to form a closed chamber, but also ensures that the lighting components of the light projector can work in a relatively stable and safe environment. While ensuring the lighting effect of the light projector, the service life of the light projector can be effectively prolonged.

[0044] The bracket 12 is in a U-shaped structure, and the opening width of the bracket 12 is comparable to the width of the heat dissipation shell 7. The bottom of the bracket 12 is in a flat plate shape and has a large area, which can better contact the mounting seat 19. The bottom and the two side plates are not directly connected, but are connected through a trapezoidal plate between the bottom and the side plates. The bottom and the side plates are connected to the waist of the trapezoidal plate, so that the bracket 12 can be inclined to support the heat dissipation shell.

[0045] The trapezoidal plate is a transition end for force transmission between the side plate and the bottom. The included angles between the trapezoidal plate and the side plate and between the trapezoidal plate and the bottom are obtuse angles. The force transmission is more gentle, and the stress distribution is more uniform. If the bottom of the bracket 12 is directly connected to the side plate, the included angle between them will be a right angle or an obtuse angle with a smaller angle. The greater the angle transition at the connection, the more rigid the transition, and the more obvious the stress concentration at this point. The material at this point is more prone to fatigue and damage.

[0046] Therefore, the trapezoidal plate can balance the force distribution on the bracket 12 to some extent, improve the mechanical properties of the bracket 12, and improve the structural strength of the bracket 12. The bottom of the bracket 12 is connected to the waist of the trapezoidal edge of one side of the trapezoidal plate, and the waist of the trapezoidal edge of the other side of the trapezoidal plate is connected to the side plate of the bracket 12. This design ensures the stability of the bracket 12 after being connected to the heat dissipation shell 7 and fixed on the mounting seat 19.

[0047] There is an obtuse angle between the side plate of the bracket 12 and the trapezoidal plate. The obtuse angle can better disperse and withstand pressure from various directions, so that the bracket 12 can still maintain excellent stability and durability when facing complex and variable installation environments. This design not only improves the overall performance of the bracket 12, but also makes the installation of the light projector more firm and reliable.

[0048] The explosion-proof net 1 is a frame structure, which is interwoven by a plurality of strips according to a specific rule. The explosion-proof net 1 has good strength and elasticity, and can effectively block and disperse impact force. On the explosion-proof net 1, a plurality of larger holes are distributed, which can protect the tempered glass 2 and the heat dissipation shell 7 from being damaged by large stones and branches, and will not block too much light emitted by the light emitting lamp.

[0049] The wide end surface of the explosion-proof net 1, in which two strips extend along the direction of the frame wall, and at the end of the strips, the strips extend inward to form a hook structure. The design of the hook structure can allow the explosion-proof net 1 to be hung on the back of the heat dissipation shell 7, so that the main structure of the explosion-proof net 1 can cover the upper opening of the heat dissipation shell 7 to protect the lighting position of the light emitting lamp.

[0050] A round hole is arranged at the end of the hook structure. In order to firmly fix the explosion-proof net 1 and the heat dissipation shell 7, it should be noted that the end surface of the position where the hook structure contacts the heat dissipation shell 7 is a flat surface, and the part where the hook structure is provided with a round hole is a circular ring structure. Correspondingly, the connecting position of the explosion-proof net 1 and the heat dissipation shell 7 is also provided with a corresponding connecting table. The explosion-proof net 1 is connected and fixed with the explosion-proof net 1 on the connecting table through the explosion-proof net fixing bolt 8. The structure of the connecting table can be similar to the structure of the mounting table when the fixing buckle 9 is mounted on the heat dissipation shell 7. The structures of the two tables are similar, and their functions are similar.

[0051] The heat dissipation shell 7 is thin at the upper end and thick at the lower end. The upper thin surface is a shallow disc structure, that is, the distance between the step surface of the heat dissipation shell 7 and the lower end surface of the heat dissipation shell is small, and the thickness of the accommodated instrument is small, so it is mainly used to place the reflecting cup 3, the lamp group 6 and the optical lens plate 5 and other lighting components with large area but small thickness.

[0052] The lower part of the heat dissipation shell 7 is a bowl-shaped chamber with a large depth, that is, the distance between the step surface of the heat dissipation shell 7 and the lower end surface of the heat dissipation shell is large. Therefore, the volume of the lower part of the heat dissipation shell 7 is large. In the lower part chamber of the heat dissipation shell 7, components with large volume and thickness, such as power box 16 and power component 17, which cannot be or are difficult to be reduced in volume, are mainly placed. The lower part of the heat dissipation shell 7 is connected with the support 12, and the power box 16 is fixedly installed in the chamber of the lower part of the heat dissipation shell 7, and the power component 17 is arranged in the power box 16.

[0053] The bottom of the shallow disc-shaped cavity at the upper part of the heat dissipation shell 7 is platform-shaped, and a plurality of holes are arranged in an array on the platform, and the lamp group 6 is mounted on the holes. The lamp group 6 is a lamp panel, and a large number of LED lamps are arranged in an array on the lamp panel. The lamp group 6 is covered with an optical lens plate 5. A large number of small convex lenses are also arranged in an array on the optical lens plate 5.

[0054] The optical lens plate 5 and the lamp group 6 are both plate-shaped structures, and the two are covered together, and the volume and thickness are also small. The optical lens plate 5 is divided into three rows and three columns, that is, nine small plates of the same size, and a plurality of small lenses are arranged in the same manner on each small plate. The small lenses correspond to the LED lamps on the lamp group 6 one by one. One small lens on the optical lens plate 5 covers one LED lamp on the lamp group 6

[0055] The optical lens plate 5 is covered with a bottomless disc-shaped reflective cup 3. The reflective cup 3 is trumpet-shaped, and the opening of the reflective cup 3 is large near the opening position of the heat dissipation shell 7, and the opening of the reflective cup 3 is small near the bottom surface of the upper cavity of the heat dissipation shell 7. The small opening of the reflective cup 3 completely encloses all the LED lamps on the lamp group 6. The reflective cup 3 is designed in a trumpet shape, which can converge the light emitted by a large number of LED lamps on the lamp group 6 and reduce the diffuse reflection. The light emitted by the whole projection lamp is more concentrated, which improves the penetration ability and illumination range of the light irradiated by the projection lamp.

[0056] A plurality of mounting holes are arranged on the optical lens plate 5, and the mounting holes are arranged in a regular manner. One mounting hole is arranged at the center of each small plate, so that the holes are arranged in the same manner on the lamp group 6. Corresponding holes are also arranged on the inner platform at the upper part of the heat dissipation shell 7. After the optical lens plate 5 and the lamp group 6 are stacked, they are attached to the heat dissipation shell 7. The mounting holes on the optical lens plate 5 are mounted with lens fixing screws 4 to fix the optical lens plate 5 and the lamp group 6 on the heat dissipation shell 7.

[0057] The tempered glass 2 completely covers the opening of the heat dissipation shell 7.

[0058] A plurality of mounting tables are arranged on the side surface of the heat dissipation shell 7. The mounting tables of the heat dissipation shell 7 cooperate with a fixing buckle 9. The fixing buckle 9 is U-shaped, and one part of the bottom surface is flat, and the other part is inclined. The fixing buckle 9 and the mounting tables cooperate to cover the tempered glass 2. The fixing buckle 9 and the mounting tables are connected by a fixing buckle bolt 10.

[0059] A hole is arranged at the lower end of the heat dissipation shell 7 to mount a breathing valve 15 and a power line 14. A waterproof joint 13 is arranged at the connection between the power line 14 and the heat dissipation shell 7.

[0060] The support 12 is provided with an expansion bolt 18 between the support 12 and the mounting base 19. The bottom of the support 12 is provided with a hole, and the support 12 is fixed on the mounting base 19 through the expansion bolt 18. It should be noted that the installation of the support 12 can also be a wall surface, a bottom surface, or other parts with high strength and firm installation, and it is not necessarily required to be the mounting base 19. In the present embodiment, it is only for the convenience of display and understanding.

[0061] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part 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 application.
