Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a health lighting lamp. Background Technology

[0002] As people become more aware of the health benefits of lighting environments, higher demands are being placed on the optical quality of lighting fixtures. Ideal healthy lighting should simultaneously possess characteristics such as high color rendering index, low glare, no blue light hazard, and no visible flicker. However, most lighting fixtures on the market currently focus on only a single indicator, lacking a systematic integration and clear requirements for the aforementioned healthy lighting parameters.

[0003] Furthermore, existing surface-mounted lighting fixtures typically use screws to connect the lampshade to the lamp body. This connection method is cumbersome to install and remove, requiring specialized tools, which inconveniences daily cleaning, maintenance, or light source replacement, and increases labor and time costs.

[0004] Therefore, there is an urgent need for a lighting fixture that can systematically meet the optical parameter requirements for healthy lighting, while also being structurally easy to install and disassemble quickly. Summary of the Invention

[0005] The purpose of this utility model is to provide a healthy lighting lamp that is easy to install and maintain, and can provide lighting that meets the needs of healthy lighting.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: A health lighting lamp includes a housing and a frame assembly detachably connected to the housing via an elastic snap-fit ​​component. The housing contains a light source assembly and an LED control device for driving the light source assembly. The light source assembly has a diffuser plate and a prism plate arranged sequentially towards the frame assembly. The light source assembly has LED beads with a color rendering index Ra≥90 and a blue light hazard level of RG0. The surface of the prism plate has a micro-prism array for constraining the light emission angle, so that the overall glare value UGR of the lighting lamp is ≤19. The LED control device is used to convert and output mains power as a low-ripple constant current to drive the light source assembly, so that the flicker visibility SVM of the lighting lamp is <1.0.

[0007] Furthermore, the driving circuit of the LED control device includes two stages: the first stage is an active power factor correction circuit, whose input terminal is connected to the mains power and is used to output a stable DC bus voltage; the second stage is a step-down constant current circuit, whose input terminal is connected to the DC bus voltage and is used to output one or more low-ripple constant currents to the light source component.

[0008] Furthermore, the elastic snap-fit ​​assembly includes a snap spring fixedly disposed on the frame assembly and a connecting piece fixedly disposed on the side wall of the housing. The snap spring has an elastic snap-fit ​​portion, and the connecting piece is provided with a slot adapted to the elastic snap-fit ​​portion. The detachable connection between the frame assembly and the housing is achieved by the elastic engagement of the elastic snap-fit ​​portion and the slot.

[0009] Furthermore, the elastic snap-fit ​​portion of the snap ring is V-shaped and consists of two opposing elastic arms; the snap-fit ​​opening on the connecting piece is formed between two parallel snap-fit ​​walls; the two elastic arms can produce opposing elastic deformations when squeezed to enter the snap-fit ​​opening, and after resetting, their outer sides abut against the inner side of the snap-fit ​​wall.

[0010] Furthermore, each of the two elastic arms has an outwardly extending limiting protrusion at its end to prevent the retaining spring from accidentally dislodging from the latch of the connecting piece.

[0011] Furthermore, the frame assembly is a rectangular frame assembled from a long frame, a short frame, and frame connectors; the inner sides of the long and short frames are provided with a first slot for limiting and fixing the diffuser plate and the prism plate, and a second slot for limiting and fixing the retaining spring. The frame structure is arranged parallel to the housing, and the long and short frames are respectively provided with the first slot for limiting and fixing the diffuser plate and the prism plate, and the second slot for limiting and fixing the retaining spring.

[0012] Furthermore, the elastic snap-fit ​​assembly also includes a snap ring retaining piece, the fixed end of the snap ring is connected to the snap ring retaining piece, and the combination of the snap ring retaining piece and the snap ring is embedded and fixed in the second snap groove.

[0013] Furthermore, the light source assembly includes a light source fixing plate and a light source plate mounted on the light source fixing plate; the light source fixing plate is fixed to the housing by fasteners; the light source plate includes an aluminum substrate and LED beads disposed thereon, the LED beads being uniformly distributed in a dot matrix.

[0014] Furthermore, the LED control device is fixedly connected to the light source fixing plate by fasteners.

[0015] Furthermore, the housing is made of stainless steel, and the diffuser plate is made of optical-grade PC, which is used to convert point light sources into uniform surface light sources.

[0016] The health lighting fixture provided by this utility model, compared with the prior art, achieves quick and detachable connection between the frame assembly and the housing through the setting of the elastic snap-fit ​​component, making the installation and maintenance of the lamp more convenient. By selecting high color rendering, harmless blue light LED beads, combined with a prism plate with a specific optical structure and a low ripple output LED control device, the four core health lighting parameters of color rendering index (Ra≥90), glare value (UGR≤19), blue light hazard level (RG0), and flicker visibility (SVM<1.0) are systematically integrated into a single lamp, providing users with a comprehensive and comfortable healthy light environment and meeting health lighting needs. In particular, the two-stage drive circuit design of the LED control device suppresses current ripple at the source, ensuring stable and flicker-free operation of the light source. Especially noteworthy is the innovative elastic snap-fit ​​component design, where the V-shaped elastic snap-fit ​​part and the bayonet replace the traditional screw fixing method. This simplifies the assembly and disassembly process of the frame assembly, facilitates daily cleaning, maintenance, and inspection, and reduces operation and maintenance costs.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0021] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0022] like Figure 1-7As shown, one embodiment of this utility model relates to a health lighting lamp, including a box-shaped housing 20 and a frame assembly 10 detachably connected to the housing 20 via an elastic snap-fit ​​component 50; the housing 20 is provided with a light source assembly 30 and an LED control device 40 for driving the light source assembly 30; the light source assembly 30 is provided with a diffuser plate 60 and a prism plate 70 in sequence facing the frame assembly 10; the light source assembly 30 is provided with LED beads with a color rendering index Ra≥90 and a blue light hazard level of RG0; the surface of the prism plate 70 has a micro prism array for constraining the light emission angle so that the overall glare value UGR of the lighting lamp is ≤19; the LED control device 40 is used to convert the mains power and output a low ripple constant current to drive the light source assembly 30, so that the flicker visibility SVM of the lighting lamp is <1.0. In one example, the housing 20, serving as the main support and heat dissipation structure of the lamp, is made of stainless steel and has an overall box-shaped structure with one open end. The light source assembly 30 includes a light source fixing plate 32 and a light source plate 31 mounted on the light source fixing plate 32. The light source fixing plate 32 is installed inside the housing 20 using screws or other fasteners. The light source plate 31 includes an aluminum substrate on which multiple LED beads are welded. These LED beads are selected to have a color rendering index (Ra) of not less than 90, enabling them to highly reproduce the true colors of objects, and their blue light hazard level meets the RG0 requirement. The LED beads are evenly distributed in a dot matrix pattern on the aluminum substrate, rather than being centrally arranged, which lays the foundation for uniform light output. The aluminum substrate is tightly attached to the light source fixing plate 32 using plastic rivets or thermally conductive adhesive, allowing heat to be conducted to the entire metal housing 20 for dissipation. The flexible snap-fit ​​component 50 enables quick and detachable connection between the frame component 10 and the housing 20, making the installation and maintenance of the lamp more convenient. By selecting high color rendering and harmless blue light LED beads, combined with a prism plate 70 with a specific optical structure and a low ripple output LED control device 40, the four core healthy lighting parameters of color rendering index (Ra≥90), glare value (UGR≤19), blue light hazard level (RG0), and flicker visibility (SVM<1.0) are systematically integrated into a single lamp, providing users with a comprehensive and comfortable healthy light environment and meeting their healthy lighting needs.

[0023] In one embodiment, a health lighting lamp is involved, in which an LED control device 40 is fixedly connected to the light source mounting plate 32 by fasteners. The driving circuit built into the LED control device 40 adopts a two-stage design: the first stage is an active power factor correction circuit, whose input terminal is connected to the AC mains power, for outputting a stable DC bus voltage; the second stage is a step-down constant current circuit, whose input terminal is connected to the DC bus voltage, for outputting one or more low-ripple constant currents to the light source assembly 30. In one example, the LED control device 40 is fixed to the end of the light source mounting plate 32 by screws and electrically connected to the light source assembly 30. The internal driving circuit of the LED control device 40 adopts a two-stage design: the first stage is an active power factor correction circuit based on a dedicated chip such as BP3619, which is connected to the AC mains power, responsible for improving the power factor and outputting a highly stable DC bus voltage; the second stage is a step-down constant current circuit based on a constant current driving chip such as BP1386, which converts the DC bus voltage into one or more precise, low-ripple constant currents to directly drive the light source board 31. This circuit structure significantly reduces output current fluctuations at the source, thereby ensuring that the final light source's flicker visibility SVM value is less than 1.0, meeting the health requirement of being flicker-free.

[0024] In one embodiment, a health lighting lamp is provided, in which a diffuser plate 60 is located directly above the light source assembly 30. The diffuser plate is made of optical-grade PC polycarbonate, which has high light transmittance and good light diffuse scattering characteristics. Its function is to disperse and mix the point-like intense light emitted by the dot-matrix LEDs below, initially transforming it into a surface light source with uniform brightness, eliminating glare. A prism plate 70, stacked on top of the diffuser plate 60, is a key component for controlling glare. It is precision-machined on a PC substrate using a mold, and its surface is densely covered with a microscopic array of prism structures. These prisms perform "secondary optical distribution" on the light that has been homogenized by the diffuser plate 60, redirecting and confining the large-angle scattered light within a set, smaller angle range. This significantly reduces the high-intensity light directly entering the human eye, thereby effectively reducing the overall glare value (UGR) of the lamp to 19 or below, achieving a low-glare, comfortable lighting standard.

[0025] In one embodiment, a health lighting lamp is provided, wherein a frame assembly 10 is used to support and fix the diffuser plate 60 and the prism plate 70, and serves as the decorative surface of the lamp. It is assembled into a rectangular frame by two long frame members 11, two short frame members 12, and four frame connectors 13. A first slot 14 and a second slot 15 are machined on the inner sides of the long frame members 11 and the short frame members 12. During installation, the edges of the stacked prism plate 70 and the diffuser plate 60 are first inserted into the first slot 14 for positioning and fixation. An elastic snap-fit ​​assembly 50 is integrated on the frame assembly 10 for quick connection with the housing 20. The frame assembly 10 includes a snap spring 52, a snap spring fixing piece 51, and a connecting piece 53 welded to the side wall of the housing 20. One end of the snap spring 52 is a fixing end 521, which is securely connected to the snap spring fixing piece 51. This assembly is then inserted into the second slot 15 of the frame profile for mounting and fixation. The other end of the retaining spring 52 consists of two opposing elastic arms 523 forming a V-shaped elastic engagement portion 522. The connecting piece 53 has a slot 531 adapted to the elastic engagement portion 522. The detachable connection between the frame assembly 10 and the housing 20 is achieved through the elastic engagement of the elastic engagement portion 522 and the slot 531. In one example, the slot 531 on the connecting piece 53 is formed between two parallel retaining walls 532. When the two elastic arms 523 are compressed, they can produce opposing elastic deformation to enter the slot 531, and after resetting, their outer sides abut against the inner side of the retaining wall 532. Preferably, the ends of the two elastic arms 523 are respectively provided with outwardly extending small hooks as limiting protrusions 524 to prevent the retaining spring 52 from accidentally dislodging from the slot 531 of the connecting piece 53.

[0026] When installing the light fixture, first assemble the elastic snap-fit ​​assembly 50, diffuser plate 60, and prism plate 70 with the frame assembly 10, aligning the opening of the V-shaped elastic snap-fit ​​part 522 of the snap spring 52 with the slot 531 of the connecting piece 53 on the housing 20. Press the two elastic arms 523 against each other; the two elastic arms 523 undergo opposing elastic deformation under pressure, narrowing their width before entering the slot 531. Once the limiting protrusion 524 passes the retaining wall 532, the pressure is released, and the elastic arms 523 open outwards under their own rebound force, tightly abutting their outer sides against the inner side of the retaining wall 532 of the connecting piece 53. Then, push the frame assembly 10 towards the housing 20 to complete the assembly of the frame assembly 10 and the housing 20. Under the rebound force of the elastic arms 523, a stable and reliable connection is formed. During disassembly, simply grasp the frame assembly 10 with your hand and pull it outwards with a little force. The elastic arm 523 of the retaining spring 52 will be squeezed and deformed by the retaining wall 532 and will exit from the retaining hole 531 until the limiting protrusion 524 stops at the retaining wall 532. The frame assembly 10 and the housing 20 will be initially separated to a fixed distance, but will still be connected by the elastic retaining assembly 50. Manually squeeze the elastic arm 523 again to make the limiting protrusion 524 avoid the retaining wall 532 and exit from the retaining hole 531, thus completing the quick disassembly of the frame assembly 10 and the housing 20.

[0027] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
