Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to lighting fixtures that prevent glass shards from falling. Background Technology
[0002] In the field of lighting technology, glass lenses are widely used as key optical components in various lighting devices. They control the light from the light source through optical effects such as refraction and focusing to meet the needs of different scenarios for light intensity, uniformity and directionality.
[0003] However, glass itself is inherently brittle, and during the actual use of lighting fixtures, glass lenses may be at risk of breakage due to various external factors. For example, in industrial settings such as factories and warehouses, they are susceptible to accidental collisions with handling equipment or goods; in homes or commercial spaces, they may be damaged due to improper installation, drops, or human contact; and in outdoor environments, they may also face problems such as wind and sand impacts and material fatigue caused by extreme temperature differences.
[0004] Once a glass lens breaks, the resulting fragments typically have irregular, sharp edges and are scattered. Without effective protective measures, these fragments can easily detach from the lamp structure and scatter into the surrounding environment, causing serious personal injuries such as cuts and punctures to nearby people. They may even cause secondary safety accidents due to the flying fragments, such as damaging high-voltage lines or creating fire hazards, significantly increasing the safety risks during the use of the lamp. Utility Model Content
[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a lighting fixture that prevents glass shards from falling. An adhesive sheet is set on the backlight side of the glass lens, and a grid is installed on the light-facing side of the glass lens. This effectively solves the safety hazard of glass shards flying and falling after breakage. It both adheres the shards to prevent them from scattering and injuring people, and blocks the shards from falling. It takes into account both lighting function and safety of use.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0025] In the field of lighting technology, glass lenses are widely used as key optical components in various lighting devices. They control the light from the light source through optical effects such as refraction and focusing to meet the needs of different scenarios for light intensity, uniformity and directionality.
[0026] However, glass itself is inherently brittle, and during the actual use of lighting fixtures, glass lenses may be at risk of breakage due to various external factors. For example, in industrial settings such as factories and warehouses, they are susceptible to accidental collisions with handling equipment or goods; in homes or commercial spaces, they may be damaged due to improper installation, drops, or human contact; and in outdoor environments, they may also face problems such as wind and sand impacts and material fatigue caused by extreme temperature differences.
[0027] Once a glass lens breaks, the resulting fragments typically have irregular, sharp edges and are scattered. Without effective protective measures, these fragments can easily detach from the lamp structure and scatter into the surrounding environment, causing serious personal injuries such as cuts and punctures to nearby people. They may even cause secondary safety accidents due to the flying fragments, such as damaging high-voltage lines or creating fire hazards, significantly increasing the safety risks during the use of the lamp.
[0028] Therefore, such as Figures 1 to 3As shown, this utility model discloses a lighting fixture for preventing glass shards from falling. It includes a lamp holder 100, a light source 111 mounted on the lamp holder 100, a glass lens 200 connected to the lamp holder 100 and located on the illumination side of the light source 111, an adhesive sheet 300 disposed on the side of the glass lens 200 facing the light source 111, and a grid 400 mounted on the lamp holder 100 and located on the side of the glass lens 200 away from the light source 111. Specifically, the adhesive sheet 300 is adhered to the surface of the glass lens 200 to adhere the broken glass lens 200, and the grid 400 is used to prevent the glass lens 200 from falling after breaking. It should be noted that an adhesive sheet 300 is provided on the side of the glass lens 200 facing the light source 111. The adhesive sheet 300 adheres to the surface of the glass lens 200. When the glass lens 200 breaks due to an accident, the adhesive sheet 300 plays a crucial adhesive role. Furthermore, due to its suitable adhesiveness, the adhesive sheet 300 can tightly bond the broken glass lens 200 fragments together, preventing the fragments from scattering and flying under the influence of gravity, vibration, and other factors. This adhesive effect can form the originally scattered fragments into a relatively stable whole, greatly reducing the possibility of direct injury to surrounding users and providing important protection for their safety. Simultaneously, a grille 400 is installed on the lamp holder 100. The grille 400 is located on the side of the glass lens 200 away from the light source 111, providing a reliable barrier effect, even if the glass lens 200 breaks... Even if the lens 200 breaks, the grille 400 can effectively prevent the broken glass lens 200 from falling. Furthermore, the design combining the adhesive sheet 300 and the grille 400 to prevent glass fragments from falling further enhances the safety of the luminaire. Even if the adhesive sheet 300 fails to completely stop the movement of fragments in certain special circumstances, the grille 400 can act as a last line of defense, confining the broken glass lens 200 inside the luminaire and preventing injury to the user. In addition, the installation of the adhesive sheet 300 and the grille 400 will not negatively affect the normal lighting function of the luminaire. They can work together with other components of the luminaire to achieve good lighting effects. While ensuring normal lighting function, it greatly improves the safety of use and effectively solves the problem of glass lens 200 fragments easily falling and injuring people in existing lighting fixtures, providing reliable protection for the user's life safety.
[0029] Refer to Figure 1 and Figure 2In some embodiments of this utility model, the lamp holder 100 is equipped with a light source plate 110, which is provided with multiple light sources 111 arranged in a dot matrix. The glass lens 200 is provided with multiple focusing slots 201, which are arranged one-to-one with the light sources 111. Furthermore, through the precise matching of the dot matrix light sources 111 and the focusing slots 201, more efficient optical utilization is achieved. The dot matrix layout of the multiple light sources 111 can be flexibly adjusted in density and position according to actual lighting needs, adapting to the uniform or focused lighting requirements of different scenarios. Moreover, the independent focusing slot 201 corresponding to each light source 111 can precisely focus the light emitted by the corresponding light source, reducing light spillage and interference between adjacent light sources, significantly improving the directionality and concentration of the light.
[0030] Optionally, the adhesive sheet 300 is a reflective paper with adhesive properties, which further endows the adhesive sheet 300 with reflective function. This not only firmly bonds broken glass lens 200 fragments together through adhesion, preventing fragments from flying or falling and causing injury, but also utilizes its high reflectivity to reflect some of the light emitted by the light source 111, reducing ineffective absorption and scattering of light inside the lens and improving light energy utilization. It is understood that the high viscosity of the reflective paper ensures a tight adhesion to the surface of the glass lens 200, while the reflective function further optimizes the lighting efficiency of the lamp, allowing more light to be emitted in a preset direction, enhancing lighting brightness and uniformity, and achieving a dual improvement in safety protection and optical performance. Specifically, in order to ensure the adhesive function of the adhesive sheet 300 while avoiding interference with the optical performance of the focusing groove 201, and referring to... Figure 2 The adhesive sheet 300 is provided with multiple clearance holes 301, which are arranged one-to-one with the focusing groove 201. It is understood that the focusing groove 201 is typically used to precisely focus the light from the corresponding light source 111. If the adhesive sheet 300 completely covers the area of the focusing groove 201, the light reflection path within the groove may be obstructed, or the adhesive material may absorb some light energy, reducing the focusing effect. To address this, by providing clearance holes 301 that precisely correspond to the positions of the focusing groove 201, the adhesive sheet 300 only covers non-critical focusing areas of the glass lens 200, such as edges or non-optical functional areas. This maintains the ability to adhere broken fragments while ensuring the unobstructed optical channel of the focusing groove 201, allowing the light from the light source 111 to pass through the focusing groove 201 and be emitted directionally without obstruction. This maximizes the preservation of the original optical performance advantages of the luminaire while ensuring safety protection.
[0031] Refer to Figure 1 and Figure 2In some embodiments of this utility model, a plurality of dot-matrix-arranged focusing protrusions 210 are provided on the side of the glass lens 200 facing away from the adhesive sheet 300, and focusing grooves 201 are arranged one-to-one on the side of the focusing protrusions 210 facing the adhesive sheet 300. It should be noted that the focusing protrusions 210 usually have a specific curved surface or prism structure, which can perform secondary refraction or reflection on the light passing through the focusing grooves 201, further converging the originally divergent light to the target area, thereby improving the local illumination intensity and uniformity, and further enhancing the directional control and focusing ability of the light. In addition, the corresponding arrangement of the focusing grooves 201 and the focusing protrusions 210 ensures that the light from each light source 111 undergoes a dual process of initial focusing by the focusing grooves 201 and secondary optimization by the focusing protrusions 210. Through the optimization of the microscopic optical structure, the light distribution is made more in line with the actual lighting needs, significantly improving the lighting quality. Further, referring to Figures 1 to 3 In some embodiments of this utility model, the grille 400 is provided with multiple grids 401, and the positions of the grids 401 correspond one-to-one with the focusing slots 201. It should be noted that the grid structure 401 of the grille 400 is mainly used to prevent broken glass lenses 200 from falling. Arranging the grids 401 one-to-one with the focusing slots 201 ensures that the light emission path corresponding to each focusing slot 201 is not excessively blocked by the grille 400, avoiding light obstruction or shadow problems caused by misalignment of the grille 400. Simultaneously, the spacing and size of the grids 401 can be designed according to the light diffusion angle of the focusing slots 201, ensuring sufficient blocking strength to prevent large fragments from passing through, while minimizing the impact on light transmission and maintaining the overall lighting efficiency of the lamp. This maximizes the preservation of the optical function of the focusing slots 201 while ensuring that glass fragments do not fall, achieving a balance between safety and lighting.
[0032] Reference Figure 1In some embodiments of this utility model, a positioning groove 402 is provided on the inner side of the grille 400, and the glass lens 200 is installed in the positioning groove 402. This provides precise installation positioning and stable fixing support for the glass lens 200, ensuring that the glass lens 200 can be quickly aligned and is not easily misaligned during installation, avoiding problems such as the misalignment of the focusing groove 201 and the light source 111, and the misalignment of the grille 401 and the focusing protrusion 210 caused by installation misalignment. In addition, the setting of the positioning groove 402 simplifies the assembly process of the lamp, improves production efficiency and assembly consistency, and ensures the stability of product quality. Optionally, the grille 400 and the lamp holder 100 are fixed with screws, which can drive the glass lens 200 to be pressed tightly onto the lamp holder 100. On the one hand, it can prevent the grille 400 from loosening or falling off due to vibration, external impact, etc., thereby continuing to perform its function of blocking glass fragments from falling; on the other hand, the axial pressure generated during the screw tightening process can press the glass lens 200 tightly onto the lamp holder 100, forming a reliable sealing and fixing effect. Furthermore, the adjustable screw fastening allows for fine-tuning of the clamping force during production or maintenance to ensure an optimal balance between installation reliability and optical performance. In some applications, the installed grille 400 abuts against the surface of the glass lens 200, further enhancing safety by preventing glass fragments from falling. This ensures that there are no gaps or only very small gaps between the grille 400 and the glass lens 200, preventing broken glass fragments from slipping out of the gap and into the outside of the luminaire. Simultaneously, the abutting contact provides additional lateral support to the glass lens 200, dispersing impact force when the luminaire is struck and reducing the risk of excessive localized stress on the glass lens 200.
[0033] Furthermore, refer to Figure 1 and Figure 2 A sealing strip 500 is provided between the glass lens 200 and the lamp holder 100, with both sides of the sealing strip 500 pressing against the lamp holder 100 and the glass lens 200 respectively. On one hand, the elastic compression of the sealing strip 500 forms an effective sealing barrier between the glass lens 200 and the lamp holder 100, filling the tiny gaps between them and preventing dust, moisture, or other external contaminants from entering the lamp fixture. This avoids contaminants adhering to the light source 111 or the lens surface, affecting optical performance or accelerating component aging. On the other hand, the buffering properties of the sealing strip 500 can absorb some energy when the lamp fixture is subjected to minor impacts or vibrations, reducing the impact force directly borne by the glass lens 200, thereby reducing the probability of breakage. Furthermore, the sealing strip 500 enhances the overall protection level of the lamp fixture, expands its applicable environmental range, and improves the product's durability and reliability.
[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
