[0002] In the field of lighting technology, point light sources are widely used in large-scale spaces such as urban building facades, media facades, and light systems. Traditional point light sources usually adopt a direct lighting form, have high brightness and strong light penetration, and are suitable for outdoor large-scale environments. However, in relatively low and small-scale spaces such as tunnels, caves, stadiums, and artistic spaces, traditional direct light sources have the following problems:

[0003] Glare problem: The light intensity of direct light sources is high, and near-distance viewing can easily cause glare, leading to visual discomfort.

[0054] According to one aspect of the present utility model, a one-lamp dual-effect point light source device 1 is provided, as shown in the reference Figures 1 to 3 , comprising:

[0055] The annular pressure casting lamp body 10 has an annular cavity with an upward opening formed by the annular side wall 11 and the bottom 12.

[0056] The first LED light source 20 is uniformly arranged along the inner side of the annular side wall 11, and the light of the first LED light source 20 can penetrate the annular side wall 11 to achieve forward diffuse transmission lighting.

[0057] The second LED light source is arranged in a uniform array on the inner side of the bottom 12 and has a U-shaped light condensing lens with a convex surface facing outward on the surface for realizing backward wide-angle reflective lighting.

[0058] The curved surface light guide glass 40 is detachably embedded in the opening end surface of the annular cavity to form a sealed optical chamber.

[0059] The first LED light source 20 and the second LED light source can be independently controlled and individually turned on or simultaneously turned on in combination.

[0060] From the above technical solution, the present utility model has the following advantages and positive effects:

[0061] The one-lamp dual-effect point light source device 1 provided by the present utility model can realize forward and backward lighting in two different directions and effects in one lamp, thereby meeting the demand for different direction lighting in different scenes, improving the use efficiency and applicability of the lamp, and avoiding the trouble of installing multiple lamps to realize different direction lighting, saving space and cost.

[0062] The annular pressure casting lamp body 10 serves as the basic framework of the entire one-lamp dual-effect point light source device 1 and provides mounting support for the first LED light source 20, the second LED light source and the curved surface light guide glass 40, etc., ensuring that each component can be accurately and stably installed at the corresponding position and guaranteeing the overall structural stability of the lamp.

[0063] Here, in some embodiments, the annular pressure casting lamp body 10 can be formed by aluminum alloy pressure casting, which has good thermal conductivity and can quickly dissipate the heat generated by the first LED light source 20 and the second LED light source. In order to improve the aesthetics and corrosion resistance of the lamp body, the annular pressure casting lamp body 10 can also be designed to have a light guide side wall with a light transmittance of 45%±5% after anodizing treatment. Anodizing can form a hard, wear-resistant and corrosion-resistant oxide film on the surface of the lamp body, which not only prevents the lamp body from rusting in humid or harsh environments, but also allows for coloring according to different needs, making the appearance of the lamp body more diverse.

[0064] The thickness of the annular side wall 11 can be reasonably designed according to the size and use requirements of the lamp. In some embodiments, the side wall thickness can be designed to be between 2-5 millimeters to ensure that the lamp body has sufficient strength to withstand the weight of the lamp itself and external force impact during installation and use.

[0065] In addition, some clamping grooves or protrusions can be designed inside the annular side wall 11 to secure the first LED light source 20.

[0066] Arranging the first LED light source 20 evenly along the inner side of the annular side wall 11 can make the light distribution of the forward diffuse transmission lighting more uniform, providing a softer and more extensive lighting effect, thereby reducing the light-dark differences in the lighting area and improving the lighting quality.

[0067] Arranging the second LED light source evenly in an array inside the bottom 12 can ensure that the light emitted by each light source is uniformly superimposed after reflection in the entire rearward lighting area, avoiding local over-brightness or over-darkness.

[0068] The surface-mounted U-shaped focusing lens with the convex surface facing outward can converge and redistribute the light emitted by the second LED light source. The originally large-angle light is refracted by the lens and transmitted to a specific rearward wide-angle direction, thereby realizing rearward wide-angle reflective lighting. This design not only effectively controls the direction of light transmission, but also improves light utilization and enhances lighting effects.

[0069] Since the first LED light source 20 and the second LED light source can be independently controlled, users can choose to turn on the first LED light source 20 or the second LED unit alone, or turn on the first LED light source 20 and the second LED light source simultaneously, i.e., at least one of the following working modes can be formed:

[0070] The first LED light source 20 is independently turned on and off; the second LED light source is independently turned on and off; the first LED light source 20 and the second LED light source are simultaneously turned on and off; and the first LED light source 20 and the second LED light source are alternately stroboscopic.

[0071] Since the thickness of the curved light guide glass 40 is not uniform, the thickness is appropriately increased at the key positions of light incidence and emission to ensure effective transmission and refraction of light; and the thickness is appropriately reduced at other positions to reduce the weight of the glass and the cost, while ensuring the stability of the overall structure.

[0072] The curved light guide glass 40 is detachably embedded in the opening end surface of the annular cavity to form a sealed optical chamber. This design not only effectively prevents dust, water vapor and other external factors from entering the interior of the lamp, thereby avoiding damage to the LED light source and other optical components, ensuring the stability of the optical performance of the lamp and prolonging the service life of the lamp; but also enables the curved light guide glass 40 to be quickly and accurately installed in place, and when the glass is damaged or needs to be cleaned and maintained, it can also be conveniently disassembled and processed, thereby effectively reducing the maintenance cost and time cost.

[0073] In some embodiments, in order to further improve the illumination uniformity and enhance the light utilization, the surface of the curved light guide glass 40 facing the annular cavity can be a light surface, and the other surface can be provided with a micro-prism array.

[0074] In this way, when the light emitted by the first LED light source 20 and the second LED light source irradiates the light surface of the curved light guide glass 40 facing the annular cavity, the light can enter the interior of the glass with a small refraction deviation due to the relatively flat light surface. This makes the propagation path of the light in the glass relatively regular, reduces the scattering loss of the light during incidence, and ensures that more light can enter the glass to participate in subsequent optical propagation. When the light propagates in the glass to the surface provided with the micro-prism array, the special geometric shape of the micro-prism can deflect the light in different directions, thereby realizing the redistribution of the light. By reasonably designing the shape, size and arrangement of the micro-prism, the exit angle and distribution range of the light can be accurately controlled to meet different lighting requirements, such as achieving more uniform diffuse transmission illumination or specific angle wide-angle reflection illumination.

[0075] In order to enable the curved light guide glass 40 to be detachably fitted to the opening end surface of the annular cavity, in some embodiments, the edge of the curved light guide glass 40 and the top end of the annular side wall 11 are designed with one provided with a protrusion and the other provided with a groove matched with the protrusion. That is, when the edge of the curved light guide glass 40 is provided with a buckle protrusion extending to the radial outside, a corresponding annular buckle groove 41 is provided at the top end of the annular side wall 11. When the top end of the annular side wall 11 is provided with a buckle protrusion extending to the radial outside, a corresponding annular buckle groove 41 is provided at the edge of the curved light guide glass 40.

[0076] In this way, the first LED light source 20 can be arranged in the mounting space formed by the buckle protrusion and the annular buckle groove 41, and through the joint action of the buckle protrusion and the annular buckle groove 41, not only the connection of the curved light guide glass 40 and the annular side wall 11 can be achieved, but also the first LED light source 20 can be fixed. In addition, during installation, the installer only needs to align the protrusion with the groove, and then the curved light guide glass 40 can be quickly and accurately placed at the top end of the annular side wall 11, greatly reducing the installation difficulty, improving the installation efficiency, and reducing the problems of poor sealing, affected optical performance and the like caused by installation errors.

[0077] On this basis, in order to further ensure the reliability of the connection between the curved light guide glass 40 and the annular side wall 11, in some embodiments, a bolt hole 80 can also be provided on the annular side wall 11, and the curved light guide glass 40 is fixed on the annular side wall 11 through cooperation of the bolt hole 80 and a bolt.

[0078] Through the positioning action of the bolt hole 80, the curved light guide glass 40 can be accurately installed at the predetermined position of the annular side wall 11, and the bolt connection can provide a larger fastening force, so that the curved light guide glass 40 and the annular side wall 11 are tightly combined, and the structural stability of the entire device is enhanced. Of course, a plurality of bolt holes 80 can be provided to make the curved light guide glass 40 or the first LED light source 20 more evenly stressed during fixation. Avoiding the local stress concentration caused by single or few bolt fixation, thereby protecting the fixed components (such as the curved light guide glass 40 may be broken due to excessive local stress), ensuring the structural stability of the entire device and the integrity of the components.

[0079] In some embodiments, the dual-effect point light source device 1 further includes a first wiring channel, which includes a first wire inlet 50 and a second wire inlet 51. The first wire inlet 50 and the second wire inlet 51 are symmetrically opened on the two side walls of the annular cavity along the diameter direction of the annular side wall 11, so that the wire can pass through the first wire inlet 50, the sealed optical cavity and the second wire inlet 51 in sequence to form a first wiring channel that passes through the sealed optical cavity.

[0080] The first wire-passing opening 50 and the second wire-passing opening 51 are symmetrically opened on the two side walls of the annular cavity along the diameter direction of the annular side wall 11, so that the wire can maintain a relatively balanced position when passing through the annular cavity, avoiding stress concentration or other potential problems caused by uneven wiring.

[0081] The presence of the first wiring channel not only provides a wire connection channel for the first LED light source 20, the second LED light source, and other optical components located in the sealed optical chamber, but also avoids the problem of wires being directly exposed to the external environment, reducing the impact of physical damage, dust, moisture, and other factors on the wires, thereby extending the service life of the wires and improving the reliability of the entire device.

[0082] In some implementations, considering that wiring within a sealed optical cavity may generate electromagnetic interference, affecting the normal operation of the first LED light source 20 and / or the second LED light source, or the performance of other electronic components, a shielding device, such as a shielding layer or shielding tube, can be installed within the wiring channel to reduce the impact of electromagnetic interference.

[0083] In addition, in some embodiments, the dual-effect point light source device 1 further includes: a first cable fixing bracket 60, one end of which is connected to the first wire insertion port 50; a second cable fixing bracket 61, one end of which is connected to the second wire insertion port 51, and the second cable fixing bracket 61 is mirror-symmetrical to the first cable fixing bracket 60; wherein, a cable guide channel is formed in the inner cavity of the first cable fixing bracket 60 and the second cable fixing bracket 61 respectively.

[0084] One end of the first cable holder 60 is connected to the first cable entry port 50, and one end of the second cable holder 61 is connected to the second cable entry port 51. In other words, each cable entry port is connected to a separate cable holder. This connection method ensures a tight fit between the cable holder and the wiring channel, allowing the wire to smoothly transition from the cable entry port into the cable holder. In some embodiments, the structural dimensions of the first cable holder 60 and the second cable holder 61 can be exactly the same, or they can be structurally identical but with slight differences in size; this invention does not impose specific limitations. Of course, having identical structural dimensions ensures the versatility of the cable holders, facilitating later maintenance and replacement.

[0085] The presence of the cable guide channel not only provides a clear guide path for the electric wire, allowing the electric wire to pass through the device in a predetermined direction, so that the installer can more easily arrange the electric wire to the correct position, and the maintenance personnel can more conveniently check and replace the electric wire; but also can prevent external impurities (such as dust, water vapor, etc.) from eroding the electric wire and the electric wire from rubbing or colliding with other components inside the device, reducing the risk of electric wire sheath wear and tear and prolonging the service life of the electric wire.

[0086] In order to be able to fix the one-lamp dual-effect point light source device 1, in some embodiments, the one-lamp dual-effect point light source device 1 further comprises a second wiring channel, which comprises:

[0087] A first through hole 71 is located on the annular side wall 11;

[0088] A second through hole 72 is mirror-imaged with the first through hole 71;

[0089] Wherein, the first through hole 71 and the second through hole 72 are communicated to enable the steel wire to sequentially penetrate the first through hole 71 and the second through hole 72.

[0090] In this way, the second wiring channel formed by the communication of the first through hole 71 and the second through hole 72 can provide a path for the fixing member 73, so that the fixing member 73 can sequentially penetrate the first through hole 71 and the second through hole 72 to realize the limitation of the annular cavity position, and ensure that displacement does not occur during work, thereby ensuring the performance and stability of the entire one-lamp dual-effect point light source device 1.

[0091] The fixing member 73 can be a steel wire, a rope or the like flexible fixing member.

[0092] In other embodiments, in order to enhance the fixing effect, the one-lamp dual-effect point light source device 1 further comprises a third wiring channel, which is structurally identical to the second wiring channel and symmetric about the first wiring channel.

[0093] That is, the third wiring channel is structurally identical to the second wiring channel, that is, it also comprises two through holes located on the annular side wall 11 and mirror-imaged with each other, and the two through holes are communicated to enable the fixing member 73 (such as a steel wire, a rope or the like flexible material) to sequentially penetrate. The consistency of such structure not only has a high standardization degree in manufacturing and design, facilitating production and assembly; but also has a more beautiful and coordinated appearance, and is helpful to maintain the balance of the device and reduce stress concentration caused by structural asymmetry in mechanical properties.

[0094] In addition, when one of the second wiring channel and the third wiring channel is damaged or unable to function normally, the other structurally identical wiring channel can replace its function, ensuring that the device can still function normally, enhancing the fault tolerance and reliability of the device.

[0095] In the utility model, the annular cavity of the one-lamp double-effect point light source device 1 is further provided with a circuit board 90 connected with the electric wire to transmit the electric energy from the external power supply to the first LED light source 20 and the second LED light source through the electric wire, ensuring that they obtain appropriate voltage and current to normally emit light.

[0096] According to the second aspect of the utility model, a wall light system is provided, as shown in Figures 7 to 9 The one-lamp double-effect point light source devices 1 are arranged on the surface of the wall in a matrix.

[0097] Since the wall light system comprises a plurality of the one-lamp double-effect point light source devices 1, the advantages and technical effects of the wall light system are similar to those of the one-lamp double-effect point light source device 1, and the utility model will not be described in detail.

[0098] It should be noted that, in the one-lamp double-effect point light source device 1 along the axis direction of the wiring channel (the first wiring channel, the second wiring channel or the third wiring channel), the other end of the first cable fixing frame 60 is connected with the second threading port 51 of the previous one-lamp double-effect point light source device 1, and the other end of the second cable fixing frame 61 is connected with the first threading port 50 of the next one-lamp double-effect point light source device 1. Moreover, in the axis direction, the second wiring channel of each one-lamp double-effect point light source device 1 passes through the same fixing member 73, and the third wiring channel of each one-lamp double-effect point light source device 1 passes through the same fixing member 73.

[0099] It should be understood that the utility model does not limit its application to the detailed structure and arrangement of the components proposed in the utility model. The utility model can have other embodiments and can be implemented and executed in various ways. The aforementioned variations and modifications fall within the scope of the utility model. It should be understood that the utility model disclosed and limited in the utility model extends to all alternative combinations of two or more individual features mentioned in the text and / or drawings.
