Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to an anti-glare embedded ceiling lamp. Background Art

[0002] Recessed ceiling luminaires, which are lamp housings or components installed in suspended ceilings, are commonly used in locations requiring uniform illumination, such as offices, schools, hospitals, and shopping malls. Recessed ceiling luminaires are designed to be embedded in suspended ceilings, maintaining a smooth surface while providing ample illumination. Anti-glare recessed ceiling luminaires are often used in scenarios where direct light exposure to the eye is crucial and visual comfort is improved. Their core function is to reduce or prevent direct light from reaching the eye, thereby minimizing glare and enhancing the comfort of the lighting environment. Anti-glare recessed ceiling luminaires not only provide sufficient brightness but also effectively reduce glare by optimizing light distribution, adding sunshades, or employing specific reflective materials, protecting eyesight and creating a more harmonious visual environment. However, anti-glare recessed ceiling luminaires require glass optical components such as diffusers and prisms. Due to the inherent fragility of these optical components, the internal structure of these anti-glare recessed ceiling luminaires is inherently weak and susceptible to damage.

[0003] The prior art announcement number CN218895308U is an one-piece embedded ceiling lamp, which discloses an one-piece embedded ceiling lamp, including a lamp body, which is stamped into one piece by hardware, and the lamp body includes a lamp board mounting groove, and the lamp board mounting groove is provided with several lamp board fixing holes and a wiring hole, and several stamped blocking pieces are provided on both sides, and several card slots are provided around the lamp body. Among them, the utility model uses the one-piece lamp body as the assembly core, assembles the lamp board, lampshade and control module on the lamp body, connects the hook through the card slot on the lamp body and hangs it on the assembly carrier, thereby completing the assembly of the lamp, and the structure is extremely simple. On the one hand, the one-piece lamp body can greatly reduce the design and production manufacturing costs, and can be formed only by stamping hardware, which is conducive to mass production. On the other hand, the assembly structure is simple, which directly reduces the difficulty and cost of installation and subsequent disassembly and replacement. Utility Model Content

[0004] In some scenarios where direct light exposure to the eye needs to be reduced and visual comfort needs to be improved, anti-glare recessed ceiling lights are needed. Their core function is to reduce or prevent direct light from reaching the eye through a series of technical means, thereby reducing glare and improving the comfort of the lighting environment. Anti-glare recessed ceiling lights not only provide sufficient lighting brightness but also effectively reduce glare by optimizing light distribution, adding sunshades, or using specific reflective materials, protecting eyesight and creating a more harmonious visual environment. However, anti-glare recessed ceiling lights require the addition of glass optical components such as diffusers and prisms. Due to the inherent fragility of these optical components, the internal structure of anti-glare recessed ceiling lights is not strong enough and is easily damaged.

[0005] To address the aforementioned technical issues, the present invention employs the following technical solutions: an anti-glare recessed ceiling light, comprising a face cover, two opposite sides of which are fixedly connected to a light source base; a light source module fixed to the light source base between the light source base and the face cover, with the anti-glare assembly clamped and fixed between the light source base and the face cover; and side end caps at both ends of the light source base, which are fixedly connected to the light source base and the face cover. The bolted connection and all-round protection provided by the side end caps enhance the structural strength of the light fixture and achieve an IP54 protection rating on the front of the product.

[0006] As a further improvement to the present invention, the light source base plate is a strip-shaped arched structure. A light source module is fixed to the inner wall of the cavity below the arch. The side of the arch is connected and fixed to the face cover via a fixing structure. The front and rear ends of the strip-shaped arched structure are connected and fixed to the side end covers. An anti-glare assembly is provided below the light source base plate. The anti-glare assembly includes a diffuser plate and a prism plate. The diffuser plate and the prism plate are snap-fitted and fixed to the lower side of the light source base plate in sequence, and fixed between the light source base plate and the face cover via a fixing structure on the side of the light source base plate. The light source base plate serves as a protective shell and a fixing structure that wraps and fixes the light source module and the anti-glare assembly, ensuring that the light source module and the anti-glare assembly are fixed while providing sufficient protection and structural strength, thereby reducing the risk of damage to the diffuser plate and the prism plate.

[0007] As a further improvement to the present invention, the side covers have bolt holes at their lower ends, which are used to securely connect the side covers to the front cover. The side covers also have slots shaped like the light source baseplate, each with screw holes. The light source baseplate and side covers snap together through the slots and are then secured with screws. The side covers securely connect the front cover and light source baseplate, ensuring structural strength while facilitating installation and protecting the sides of the light source module and anti-glare assembly.

[0008] As a further improvement to the present invention, a power drive assembly is provided on the front cover. This assembly includes a junction box, one end of which is connected to the power interface via a wire, and the other end is connected to the driver input. The driver output is connected to the light source module via a connecting wire. A wiring hole is provided on the light source base plate, through which the connecting wire enters and connects to the light source module. The power drive assembly is fixed to the front cover. The power drive assembly is separated from the light source module and anti-glare assembly, reducing the risk of damage to the light source module and anti-glare assembly.

[0009] The beneficial effects of the present invention are as follows: the structural design of the product is simple and easy to install. As a recessed ceiling lamp, it not only maintains the flatness of the ceiling surface, but also provides sufficient lighting, reduces glare, and improves the comfort of the lighting environment. It also has sufficient structural strength to achieve an IP54 protection level on the front of the product, and provides adequate protection for the easily damaged light source module and anti-glare components.

DETAILED DESCRIPTION

[0014] Example 1: Figure 1 and Figure 2The figure shows an anti-glare recessed ceiling light, comprising a face cover 1, with a light source base 2 secured to it on both sides by screws. A light source module 3 is positioned between the light source base 2 and the face cover 1, and the anti-glare assembly is clamped between the light source base 2 and the face cover 1. Side end caps 4 are mounted on the front and rear sides of the face cover 1, secured to the face cover 1 by bolts and then to the light source base 2 via slots and screws. The bolted connection and all-round protection provided by the side end caps 4 enhance the structural strength of the light source base 2 and the face cover 1, ensuring the product achieves an IP54 front-facing protection rating. The IP rating (also known as the Ingress Protection rating or International Protection Marking) is a standard developed by the International Electrotechnical Commission (IEC) that defines the degree of protection provided by the enclosure of electrical equipment against intrusion by foreign objects. The IP rating consists of two digits: the first digit represents the degree of dustproofing, and the second digit represents the degree of water resistance. The first digit, "5," represents the dustproofing rating. The IP rating ranges from 0 to 6, with higher digits indicating greater dustproofing. An IP5 rating for dust resistance means the device is protected from foreign objects and dust, but it's not completely dust-proof. Specifically, it doesn't prevent dust from penetrating, but the amount of dust that enters won't interfere with normal operation or cause damage to the device's internal components. The second digit, "4," represents the level of water resistance. The IP rating also ranges from 0 to 8, with higher numbers indicating greater water resistance. An IP4 rating means the device is protected against splashing water, but only from vertically falling water drops. This means that when the device is in its normal installation position, water splashing from any direction (such as rain or splashing water) will not cause any harmful effects. In summary, devices with an IP54 rating offer moderate dust and water resistance, suitable for most indoor and outdoor environments, but not for direct immersion in water or exposure to high-pressure water jets. This level of protection is commonly found in applications requiring a certain level of dust and water resistance, such as household appliances, industrial control equipment, and outdoor lighting.

[0015] As a further improvement of the present invention, the light source base plate 2 is a strip-shaped arch structure, and a light source module 3 is fixed to the inner wall of the cavity below the arch. The side of the arch is connected and fixed to the pressing plate and the surface cover 1 by screws, and the two ends of the strip-shaped arch structure are fixed to the side end covers 4 by screws. An anti-glare component is provided below the light source base plate 2, and the anti-glare component includes a diffuser plate 5 and a prism plate 6. The diffuser plate 5 is an element that diffuses light by multiple scattering. It utilizes the physical phenomenon of refraction, reflection and scattering when light encounters two media with different refractive indices during its path, causing the light to refract, reflect and scatter in different directions, thereby changing the path of the light, achieving full dispersion of the incident light, and producing an optical diffusion effect. The main function of the diffuser plate 5 is to make the light distribution uniform, reduce the light intensity, and achieve a soft and uniform illumination effect. It is widely used in liquid crystal displays, LED lighting and imaging display systems. The diffuser plate 5 is typically made of organic glass (such as PMMA, PC, PS, PP, etc.) or similar materials, with special surface treatments, such as the addition of inorganic or organic light diffusers or the artificial alignment of light through an array of micro-feature structures on the substrate surface. The prism plate 6 is an important optical component whose primary function is to split incident light into multiple beams and redirect these beams. Prism plate 6 is typically made of glass or crystal, with finely angular surfaces that refract and reflect light multiple times, minimizing the separation of the beams. In optical devices, prism plate 6 is often used to converge light emitted from the diffuser plate 5, which diverges at various angles, onto a specific axial angle, such as that toward a liquid crystal cell. Light that deviates significantly from the axial angle is reflected back to the light guide plate, where it is reflected again by the reflector plate before passing through prism plate 6. Prism plate 6 and diffuser plate 5 are often used together in optical devices, achieving enhanced performance. Properly used together, optical devices can achieve improved optical performance and adaptability. For example, in an LCD display, the diffusion plate 5 makes the light evenly distributed, while the prism plate 6 is responsible for converging the light onto the liquid crystal cells, thereby improving the display quality.

[0016] As a further improvement to the present invention, the diffuser plate 5 and prism plate 6 are sequentially snap-fitted to the underside of the light source base plate 2, and secured between the light source base plate 2 and the cover 1 via screws and tabs on the side of the light source base plate 2. The light source base plate 2 acts as a protective shell and fixed structure, encasing and securing the light source module 3 and the anti-glare assembly. This ensures that the light source module 3 and the anti-glare assembly are fixed while providing adequate protection and structural strength, reducing the risk of damage to the diffuser plate 5 and prism plate 6.

[0017] As a further improvement to the present invention, the lower end of the side cover 4 is provided with a bolt connection hole, which secures the side cover 4 to the front cover 1 via bolts. The side cover 4 is provided with a slot shaped to correspond to the light source base plate 2, and the slot is provided with a screw hole. The light source base plate 2 engages the side cover 4 through the slot and is then secured with screws. The side cover 4 secures the front cover 1 and light source base plate 2, ensuring structural strength while facilitating installation and protecting the sides of the light source module 3 and the anti-glare assembly.

[0018] As a further improvement to the present invention, the power driver assembly includes a junction box 9, one end of which is connected to the power interface via a wire, and the other end is connected to the input of the driver 8. The output of the driver 8 is provided with a connecting wire 7 connected to the light source module 3. The light source base plate 2 is provided with a wiring hole 13, through which the connecting wire 7 enters and connects to the light source module 3. The power driver assembly is fixed to the cover 1. The power driver assembly is arranged separately from the light source module 3 and the anti-glare assembly, reducing the risk of damage to the light source module 3 and the anti-glare assembly.

[0019] Example 2: Figure 1 and Figure 2The figure shows an anti-glare recessed ceiling light, comprising a face cover 1, with a light source base 2 secured to it on both sides by screws. A light source module 3 is positioned between the light source base 2 and the face cover 1, and the anti-glare assembly is clamped between the light source base 2 and the face cover 1. Side end caps 4 are mounted on the front and rear sides of the face cover 1, secured to the face cover 1 by bolts and then to the light source base 2 via slots and screws. The bolted connection and all-round protection provided by the side end caps 4 enhance the structural strength of the light source base 2 and the face cover 1, ensuring the product achieves an IP54 front-facing protection rating. The IP rating (also known as the Ingress Protection rating or International Protection Marking) is a standard developed by the International Electrotechnical Commission (IEC) that defines the degree of protection provided by the enclosure of electrical equipment against intrusion by foreign objects. The IP rating consists of two digits: the first digit represents the degree of dustproofing, and the second digit represents the degree of water resistance. The first digit, "5," represents the dustproofing rating. The IP rating ranges from 0 to 6, with higher digits indicating greater dustproofing. An IP5 rating for dust resistance means the device is protected from foreign objects and dust, but it's not completely dust-proof. Specifically, it doesn't prevent dust from penetrating, but the amount of dust that enters won't interfere with normal operation or cause damage to the device's internal components. The second digit, "4," represents the level of water resistance. The IP rating also ranges from 0 to 8, with higher numbers indicating greater water resistance. An IP4 rating means the device is protected against splashing water, but only from vertically falling water drops. This means that when the device is in its normal installation position, water splashing from any direction (such as rain or splashing water) will not cause any harmful effects. In summary, devices with an IP54 rating offer moderate dust and water resistance, suitable for most indoor and outdoor environments, but not for direct immersion in water or exposure to high-pressure water jets. This level of protection is commonly found in applications requiring a certain level of dust and water resistance, such as household appliances, industrial control equipment, and outdoor lighting.

[0020] As a further improvement to the present invention, the light source base plate 2 is a strip-shaped arched structure. A light source module 3 is fixed to the inner wall of the cavity below the arch. The sides of the arch are screwed to the pressing plate and the cover 1. The ends of the strip-shaped arch are screwed to the side end caps 4. The light source module 3 is glued to the bottom of the light source base plate 2. The adhesive connection does not require additional bolt structure design, making installation more convenient. An anti-glare assembly is provided below the light source base plate 2. The anti-glare assembly includes a diffuser plate 5 and a prism plate 6. The diffuser plate 5 is an element that diffuses light through multiple scattering. It utilizes the physical phenomena of refraction, reflection, and scattering when light encounters two media with different refractive indices during its path. This causes the light to refract, reflect, and scatter in different directions, thereby changing the light's path and achieving sufficient dispersion of the incident light, producing an optical diffusion effect. The diffuser plate 5's main function is to even out the light distribution, reduce light intensity, and achieve a soft, uniform illumination effect. It is widely used in liquid crystal displays, LED lighting, and imaging display systems. The diffuser plate 5 is typically made of organic glass (such as PMMA, PC, PS, PP, etc.) or similar materials, with special surface treatments, such as the addition of inorganic or organic light diffusers or the artificial alignment of light through an array of micro-feature structures on the substrate surface. The prism plate 6 is an important optical component whose primary function is to split incident light into multiple beams and redirect these beams. Prism plate 6 is typically made of glass or crystal, with finely angular surfaces that refract and reflect light multiple times, minimizing the separation of the beams. In optical devices, prism plate 6 is often used to converge light emitted from the diffuser plate 5, which diverges at various angles, onto a specific axial angle, such as that toward a liquid crystal cell. Light that deviates significantly from the axial angle is reflected back to the light guide plate, where it is reflected again by the reflector plate before passing through prism plate 6. Prism plate 6 and diffuser plate 5 are often used together in optical devices, achieving enhanced performance. Properly used together, optical devices can achieve improved optical performance and adaptability. For example, in an LCD display, the diffusion plate 5 makes the light evenly distributed, while the prism plate 6 is responsible for converging the light onto the liquid crystal cells, thereby improving the display quality.

[0021] As a further improvement to the present invention, the diffuser plate 5 and prism plate 6 are sequentially snap-fitted to the underside of the light source base plate 2, and secured between the light source base plate 2 and the cover 1 via screws and tabs on the side of the light source base plate 2. The light source base plate 2 acts as a protective shell and fixed structure, encasing and securing the light source module 3 and the anti-glare assembly. This ensures that the light source module 3 and the anti-glare assembly are fixed while providing adequate protection and structural strength, reducing the risk of damage to the diffuser plate 5 and prism plate 6.

[0022] As a further improvement to the present invention, the lower end of the side cover 4 is provided with a bolt connection hole, which secures the side cover 4 to the front cover 1 via bolts. The side cover 4 is provided with a slot shaped to correspond to the light source base plate 2, and the slot is provided with a screw hole. The light source base plate 2 engages the side cover 4 through the slot and is then secured with screws. The side cover 4 secures the front cover 1 and light source base plate 2, ensuring structural strength while facilitating installation and protecting the sides of the light source module 3 and the anti-glare assembly.

[0023] As a further improvement of the present invention, different from the first embodiment, Figure 3 As shown, the side cover 4 has a hollow 10 in the middle, and strip-shaped slits 11 are provided on both sides near the light source base plate 2. These hollow 10 and strip-shaped slits 11 provide space for mounting with hanging wires and spring clips, expanding the product's application range. The bottom of the side cover 4 also features fixing ribs 12, which snap onto the diffuser plate 5 and prism plate 6 to provide reinforcement.

[0024] As a further improvement of the present invention, the power drive assembly includes a junction box 9, one end of which is connected to the power interface through an electric wire, and the other end is connected to the input end of the driver 8. The output end of the driver 8 is provided with a connecting wire 7 connected to the light source module 3. A wiring hole 13 is provided on the light source base plate 2, and the connecting wire 7 enters the wiring hole 13 to connect to the light source module 3.
