Description

Technical field

[0001] The utility model relates to the field of lighting technology, in particular a luminaire. State of the art

[0002] A luminaire, as a common lighting device, typically comprises a luminaire body and a translucent cover. The luminaire body has a cavity to house an optoelectronic component, and the translucent cover seals this cavity. To ensure the luminaire's watertightness, most luminaires currently use an adhesive bonding method to seal the mounting gap. However, this bonding method has the following disadvantages: Firstly, the adhesive's sealing effect is unstable, which can easily lead to adhesive defects or breaks, resulting in inadequate sealing and compromising the luminaire's watertightness. Secondly, once cured, the adhesive exhibits high bond strength, making it impossible to remove the translucent cover from the luminaire body without damage, thus complicating maintenance of the optoelectronic components inside the luminaire.

[0016] The achievement of the purpose, the functional features and the advantages of this utility model are explained in more detail in conjunction with exemplary embodiments and with reference to the drawings. Designs

[0017] The technical solutions of the embodiments of this utility model are described clearly and completely below with reference to the drawings. Obviously, the described embodiments represent only a subset of the embodiments of this utility model, not all of them. All further embodiments that experts in this field achieve without inventive work based on the embodiments of this utility model also fall within the scope of protection of this utility model.

[0018] It should be explained that in the embodiments of this utility model, all directional indications (such as above, below, left, right, front, back, etc.) serve exclusively to explain the relative positions and movements of the respective components in a specific posture (as shown in the drawings); if this specific posture changes, the directional indications change accordingly.

[0019] As in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, in an embodiment of this utility model, the luminaire 1000 comprises the following: a luminaire body 100, wherein the luminaire body 100 has a cavity 100a with an opening; an elastic ring 300, the surface of which is formed with a groove 300a, wherein a cavity wall is inserted into the groove 300a at the opening of the cavity 100a; a translucent cover 500, which is arranged on the surface of the elastic ring 300 facing away from the groove 300a; and a connecting assembly 700, wherein the connecting assembly 700 serves to tighten or unlock the translucent cover 500 on the luminaire body 100 in order to seal or open the cavity 100a.

[0020] In the technical solutions of this utility model, a cavity 100a with an opening is formed in the luminaire body 100, in which an optoelectronic component 110 is arranged, a groove 300a is formed on the surface of the elastic ring 300, and the cavity wall at the opening of the cavity 100a is inserted in the groove 300a of the elastic ring 300, the translucent cover 500 is arranged on the surface of the elastic ring 300 facing away from the groove 300a, so that when pressure is applied to the translucent cover 500, the translucent cover 500, the elastic ring 300 and the cavity wall of the cavity 100a lie close together. This means that the translucent cover 500 is tightened onto the luminaire body 100 by means of the connecting assembly 700, thereby sealing the cavity 100a, preventing water from entering the cavity 100a and ensuring the watertightness of the luminaire 1000.When the connecting assembly 700 unlocks the translucent cover 500 on the luminaire body 100, the cavity 100a can be opened, thus enabling maintenance of the optoelectronic component 110 inside the luminaire 1000. This utility model ensures the watertightness of the luminaire 1000 while simultaneously facilitating maintenance of the optoelectronic component 110 inside.

[0021] It should be explained that in this embodiment, the arrangement of the groove 300a facilitates the insertion of the elastic ring 300 into the luminaire body 100. The groove 300a can have various shapes, as long as a tight fit of the elastic ring 300 to the cavity wall of the cavity 100a is ensured. Preferably, the groove 300a can be designed as an annular groove. The circumferential wall of the cavity 100a is inserted into the annular groove, thereby stabilizing the mounting of the elastic ring 300 and simultaneously improving the water resistance class of the luminaire 1000. The translucent cover 500 of this embodiment can consist of flat glass, organic glass, or a PC sheet (where PC stands for polycarbonate sheet), as long as the light from the luminaire body 100 can be emitted.Furthermore, the elastic ring 300 is arranged projecting from the cavity wall of the cavity 100a, and the translucent cover 500 covers the elastic ring 300. Under pressure, the translucent cover 500, the elastic ring 300, and the cavity wall of the cavity 100a lie close together, so that the connecting assembly 700 tightens the translucent cover 500 onto the luminaire body 100 to seal the cavity 100a. Naturally, the type of movable connection of the connecting assembly 700 includes a threaded connection, a snap connection, a locking connection, or the like, as long as the tightening and unlocking of the translucent cover 500 on the luminaire body 100 is possible. This embodiment is not limited to this and is entirely within the scope of protection of this utility model.In this embodiment, the cavity 100a is sealed by the arrangement of the elastic ring 300, thereby achieving a water resistance rating of IP66 for the luminaire 1000. Furthermore, in this embodiment, the elastic ring 300 is arranged between the translucent cover 500 and the luminaire body 100, with the translucent cover 500 not making contact with the luminaire body 100. When glass is used as the translucent cover 500, this effectively prevents glass breakage and achieves an impact resistance rating of IK08 or higher for the luminaire 1000.

[0022] See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7; In one embodiment, the groove 300a comprises an interconnected guide opening 301a and a mounting groove 302a, wherein the opening width of the guide opening 301a is larger than that of the mounting groove 302a. The groove wall of the mounting groove 302a is in an interference fit with the cavity wall of the cavity 100a. It should be emphasized that in this embodiment, the arrangement of the guide opening 301a with a larger opening width than the mounting groove 302a allows the elastic ring 300 to be mounted via the guide opening 301a by being guided against the cavity wall of the cavity 100a, thus facilitating the mounting of the elastic ring 300 on the luminaire body 100.Furthermore, the groove wall of the mounting groove 302a is in an interference fit with the cavity wall of the cavity 100a, thus achieving a watertight seal between the elastic ring 300 and the luminaire body 100, thereby preventing water from penetrating the cavity 100a through the gap between the elastic ring 300 and the luminaire body 100. Naturally, the interference fit between the groove wall of the mounting groove 302a and the cavity wall of the cavity 100a can be achieved by continuously varying the diameter of the mounting groove 302a or by providing the groove wall of the mounting groove 302a with a projection, which can be, for example, a triangular or trapezoidal wedge block; similarly, the cavity wall of the cavity 100a can have a projection. The only requirement is that the interference fit between the groove wall of the mounting groove 302a and the cavity wall of the cavity 100a is achieved.This utility model is not limited by this; the above lies within the scope of protection of this utility model.

[0023] See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7. In one embodiment of this utility model, a rounded projection 311 is formed on the side wall of the mounting groove 302a, against which the cavity wall of the cavity 100a abuts, so that the elastic ring 300 rests against the cavity wall of the cavity 100a by means of an interference fit. It should be explained that in this embodiment, the formation of the rounded projection 311 on the side wall of the mounting groove 302a allows the cavity wall of the cavity 100a to be inserted smoothly into the groove 300a of the elastic ring 300, thereby preventing the elastic ring 300 from catching during assembly on the luminaire body 100.The cavity wall of the cavity 100a rests against the rounded projection 311, creating an interference fit between the groove wall of the mounting groove 302a and the cavity wall 100a of the cavity 100a, which achieves watertightness between the elastic ring 300 and the luminaire body 100 and thus increases the watertightness class of the luminaire 1000.

[0024] See Fig. 1 to Fig. 7. In one embodiment of this utility model, a rounded projection 311 is formed on each of the two opposing side walls of the mounting groove 302a. The two rounded projections 311 of the mounting groove 302a are arranged opposite each other, and the cavity wall of the cavity 100a is positioned between the two rounded projections 311. It should be explained that in this embodiment, by clamping the cavity wall of the cavity 100a between the two opposing rounded projections 311, the cavity wall of the cavity 100a is in an interference fit simultaneously with the two opposing side walls of the mounting groove 302a, thus forming two watertight seals.This prevents water from entering the interior of the cavity 100a through the gap between the elastic ring 300 and the luminaire body 100, and further improves the water tightness between the elastic ring 300 and the luminaire body 100, thereby increasing the water tightness class of the luminaire 1000.

[0025] See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7. In one embodiment of this utility model, the elastic ring 300 comprises an opposing slot 310 and a projection 330. A groove 300a is formed on the surface of the slot 310 facing away from the projection 330, with the upper part of the projection 330 bearing against the translucent cover 500 to ensure an interference fit with the translucent cover 500. It should be noted that in this embodiment, the projection 330 extends beyond the cavity wall of the cavity 100a, and when the translucent cover 500 covers the projection 330, the projection 330 undergoes elastic deformation under pressure, thereby forming an interference fit with the translucent cover 500.This achieves watertightness between the elastic ring 300 and the translucent cover 500, in order to prevent water from penetrating the cavity 100a through the gap between the elastic ring 300 and the translucent cover 500, thus increasing the watertightness class of the luminaire 1000.

[0026] Referring to the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. In one embodiment of this utility model, the elastic ring 300 comprises several extensions 330, wherein several extensions 330 are arranged side by side on the slot connector 310, so that the elastic ring 300 is in press fit with the translucent cover 500 by means of several extensions 330.It should be explained that in this embodiment, the elastic ring 300 can have a corresponding number of extensions 330 according to the number pi; specifically, three extensions 330 are arranged on the surface of the slot plug 310, with the three extensions 330 each projecting from the cavity wall of the cavity 100a, the elastic ring 300 being in a press fit with the translucent cover 500 by means of three extensions 330, which form three watertight seals and further prevent water from penetrating the cavity 100a through the gap between the elastic ring 300 and the translucent cover 500, thereby increasing the watertightness class of the luminaire 1000.In this embodiment, the translucent cover 500 can be made of glass, wherein the elastic ring 300 rests against the translucent cover 500 made of glass by means of several projecting extensions 330, so that there is a certain distance between the translucent cover 500 and the luminaire body 100, thereby preventing glass breakage due to contact of the glass with the luminaire body 100, and increasing the water resistance class of the luminaire 1000.

[0027] See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7. In one embodiment of this utility model, a through-hole 500a is formed at the outer edge of the translucent cover 500 projecting from the elastic ring 300, and the connecting assembly 700 is movably guided through the through-hole 500a so that the translucent cover 500 can be tightened or unlocked on or off the luminaire body 100. It should be explained that in this embodiment, by forming the through-hole 500a at the outer edge of the translucent cover 500 projecting from the elastic ring 300, wherein the connecting assembly 700 is movably guided through the through-hole 500a so that the translucent cover 500 can be tightened or unlocked on or off the luminaire body 100, the watertight function of the luminaire 1000 is ensured and the gap of the optoelectronic component 110 is facilitated.The connecting assembly 700 can be connected to the luminaire body 100 either via a threaded connection or via a locking connection; this utility model is not limited to this, and the above falls within the scope of protection of this utility model. It should be further noted that the optoelectronic component 110 comprises a light plate 111, a lens 112, and a power supply 113; the light plate 111, the lens 112, and the power supply 113, etc., are each arranged in the cavity 100a. In addition, a lightning protection device 120, a waterproof connector 130, and an oxygen sensor 140 can be provided. An angle adjuster 150 is attached to the luminaire body 100. The luminaire 1000 is mounted and fixed via the angle adjuster 150, thereby enabling adjustment of the angle of the luminaire 1000.The embodiment of this utility model is not limited to this; the above is within the scope of protection of this utility model.

[0028] See the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7. In one embodiment of this utility model, the thickness of the translucent cover 500 is defined as T. The side edge of the translucent cover 500 closest to the through-hole 500a is referred to as the adjacent side edge. The distance L between the bore edge of the through-hole 500a and the adjacent side edge of the translucent cover 500 is 1.5T to 2.5T.It should be noted that the translucent cover 500 of this embodiment has four side edges, the side edge closest to the through-hole 500a being defined as the adjacent side edge. In this embodiment, the bore location is positioned based on the thickness of the translucent cover 500, thereby enabling the mounting and fixing of the connecting assembly 700. At the same time, this prevents edge breakage of the translucent cover 500 by the bore, particularly if the translucent cover 500 is a glass component, thus effectively preventing glass breakage. Furthermore, it ensures the translucent surface of the translucent cover 500 is sufficient to meet the lighting requirements.

[0029] See Fig. 1 to Fig. 7, in an embodiment of this utility model, the connecting assembly 700 comprises a pressure element 710 and a threaded element 730, wherein the pressure element 710 is arranged on the surface of the translucent cover 500 facing away from the elastic ring 300 and rests against the lamp body 100, and the threaded element 730 is successively guided through the pressure element 710 and the through-hole 500a and screwed onto the lamp body 100. It should be explained that by placing the pressure element 710 against the edge of the luminaire body 100 in this embodiment, a limitation of the pressure element 710 is achieved, thereby preventing rotation of the pressure element 710 during the threaded locking of the threaded element 730 and thus ensuring a locking effect of the threaded element 730 between the translucent cover 500 and the luminaire body 100, which ensures the watertight function of the luminaire 1000.Specifically, the threaded element 730 can be a screw. To further ensure the watertight function of the luminaire 1000, several connecting assemblies 700 can also be provided in this embodiment if required, with the several connecting assemblies 700 each being arranged on different side edges of the translucent cover 500. However, this embodiment is not limited to this; the above falls within the scope of protection of this utility model.

[0030] See the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig.7. In one embodiment of this utility model, the pressure element 710 comprises a pressure disk 711 and an elastic disk 713, wherein the elastic disk 713 and the pressure disk 711 are arranged successively on the surface of the translucent cover 500. The side edge of the pressure disk 711 projects beyond the circumferential edge of the translucent cover 500 and rests against the luminaire body 100. It should be explained that the side edge of the pressure disc 711 extends beyond the circumferential edge of the translucent cover 500 and rests against the luminaire body 100, the pressure disc 711 adheres to the elastic disc 713, thereby limiting the pressure element 710 by means of the pressure disc 711 in order to prevent rotation of the threaded element 730 during the thread locking and thus ensure the locking effect between the translucent cover 500 and the luminaire body 100.Furthermore, the elastic disc 713 is arranged between the pressure plate 711 and the translucent cover 500, and when a translucent cover 500 is used, this prevents the glass from breaking due to contact with the pressure plate 711. Of course, in this embodiment, the area of ​​the elastic disc 713 can also be increased accordingly in order to increase the stressed area of ​​the glass, prevent glass breakage, and achieve a protection class of IK08 or higher.
