Description

Technical Field

[0001] This utility model relates to the technical field of phosphorless LED light-emitting devices, and in particular to a phosphorless LED side-emitting module and side-emitting device. Background Technology

[0002] As the concept of energy conservation and environmental protection gains increasing popularity, LED lighting technology, as a green and energy-saving lighting solution, has been widely applied in various lighting equipment. Traditional LED lighting modules mainly rely on a combination of blue LEDs and phosphors, with white light emission achieved through phosphor excitation. However, with the continuous development of LED technology, phosphorless LEDs are gradually becoming an innovative technological trend. Compared with traditional LEDs, phosphorless LEDs achieve color light control through other technologies (such as RGB three-color light sources, quantum dot technology, etc.), resulting in higher luminous efficacy, better color rendering, and longer lifespan. They are particularly suitable for high-power, large-scale lighting applications. Against this backdrop, the combination of phosphorless LED side-emitting modules with streetlights makes streetlights more energy-efficient, highly effective, and environmentally friendly.

[0003] Existing streetlights typically consist of a large rectangular lamp head, a base, and a pole. The rectangular lamp head has both surface and backlight sources. The surface light source is used to illuminate the tabletop, while the backlight source is used for ambient lighting. These features high luminous flux and illumination. However, in actual use, streetlights need to be disassembled for transport or sale. The connection between the lamp head and the pole is often a simple threaded connection, and the large unsupported portion of the lamp head makes it difficult for users or installers to quickly connect the lamp head and pole during disassembly and reassembly, thus reducing installation efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a phosphorless LED side-emitting device, which aims to improve the installation efficiency of lamps.

[0005] To achieve the above objectives, this utility model proposes a phosphorless LED side-emitting device, comprising:

[0006] The light pole has a hollow pole body with openings at both ends, and a limit slot is provided at the upper end of the light pole;

[0007] The lamp head is detachably and fixedly connected to the limiting slot;

[0008] A connecting sleeve, which is detachably and fixedly connected to the end of the lamp post away from the lamp head;

[0009] A snap-fit ​​assembly is provided in a limiting slot to facilitate the positioning and snap-fit ​​of the lamp head and the lamp pole.

[0010] In one possible implementation, the snap-fit ​​assembly includes:

[0011] A positioning plate, which is fixedly connected to the lamp head on the side near the lamp post;

[0012] A positioning seat is fixedly connected to the inner wall of the connecting sleeve. A locking plate is hinged to the positioning seat, and a locking block is fixedly connected to the upper end of the locking plate. The locking block is engaged with the upper side of the positioning plate.

[0013] The reset plate slides and abuts against the inner wall of the connecting sleeve, and the reset plate abuts against the inclined side of the locking plate;

[0014] A reset post is fixedly connected to the outside of the connecting sleeve, and a reset spring is fitted on the reset post.

[0015] The transmission plate slides and abuts against the outer wall of the connecting sleeve, and the two ends of the return spring of the transmission plate abut against the transmission plate and the outer wall of the connecting sleeve, respectively.

[0016] In one possible implementation, a locking groove is provided on the side of the positioning plate, the locking groove is inclined downward toward the positioning seat, and the locking block fits into the shape of the inner wall of the locking groove.

[0017] In one possible implementation, a counter-pressure groove is provided on the lower side of the positioning plate, and a counter-pressure block is abutted against the inner wall of the counter-pressure groove. The counter-pressure block is fixedly connected to the inner wall of the connecting sleeve.

[0018] In one possible implementation, a lamp holder is fixedly connected to the side of the lamp post away from the lamp head.

[0019] In one possible implementation, a control module for controlling the light source of the lamp head is provided in the middle section of the lamp post.

[0020] In this utility model, the user can hold the lamp head at an angle and insert the positioning plate into the limiting slot using the snap-fit ​​assembly. The positioning plate moves the locking block forward, and when the locking plate contacts the reset plate, the snap-fit ​​assembly securely engages the positioning plate in the limiting slot, allowing for a quick pre-connection between the lamp head and the lamp pole. The user can clearly understand the connection status. Subsequently, the user can fix the lamp head and lamp pole together with screws. This pre-connection method also facilitates the user or installer to adjust the lamp head's illumination, thereby adjusting the lamp head's working mode and the connection status between the lamp head and the lamp pole. This not only reduces the difficulty of subsequent installation but also improves the installation efficiency of the device. In addition, the connecting sleeve is used to support the connection between the lamp head and the lamp pole, preventing the lamp pole itself from being subjected to wear from the threaded connection and further improving the service life of the lamp pole.

[0021] Another objective of this invention is to provide a phosphorless LED side-emitting module, which aims to improve the luminous efficiency and lifespan of lamps.

[0022] To achieve the above objectives, this utility model proposes a phosphorless LED side-emitting module, wherein the lamp head is provided with a backlight and a sidelight respectively on its upper and lower end faces. The sidelight includes a phosphorless LED with golden yellow light containing red and yellow light and a color temperature LED light strip. A light-diffusing plate is fixedly connected to the side of the lamp head facing the backlight and the sidelight.

[0023] In one possible implementation, the lamp head includes a lamp frame, an annular groove is provided at the outer edge of the lamp frame, the side light source is disposed in the annular groove, and a clamping plate is snapped onto the lamp frame to limit the side light source.

[0024] This invention utilizes a surface light source and a backlight source to provide uniform illumination, resulting in a more balanced distribution of light sources. This improves the overall brightness and luminous efficacy of the luminaire, avoiding strong shadows or excessively high local brightness. The side light source, being a phosphorless light-emitting diode (LED), boasts high luminous efficacy and a long lifespan. By placing the side light source within an annular groove, combined with the effect of a light-diffusing plate, the divergence angle of the light source is effectively expanded, making the illumination more uniform and avoiding overly concentrated or uneven illumination in certain areas. Through the rational configuration of the surface light source, backlight source, and side light source, combined with the design of the light-diffusing plate, the overall illumination effect is more uniform and comfortable, meeting the needs of a wider range of applications.

[0035] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] Example 1

[0038] This utility model proposes a phosphorless LED side-emitting device;

[0039] Reference Figures 1 to 7 In this embodiment of the utility model, the phosphorless LED side-emitting module includes:

[0040] The lamp post 11 has a hollow pole body with openings at both ends, and a limit slot 12 is provided at the upper end of the lamp post 11.

[0041] The lamp holder 13 is detachably and fixedly connected to the limiting slot 12;

[0042] The connecting sleeve 14 is detachably and fixedly connected to the end of the lamp post 11 away from the lamp head 13;

[0043] A snap-fit ​​assembly is provided in the limiting slot 12 to facilitate the positioning and snap-fit ​​of the lamp head 13 and the lamp pole 11.

[0044] Using the snap-fit ​​assembly, the user can hold the lamp head 13 at an angle and insert the positioning plate 21 into the limiting slot 12. The positioning plate 21 drives the locking block 24 forward. When the locking plate 23 and the reset plate 25 come into contact, the snap-fit ​​assembly securely engages the positioning plate 21 in the limiting slot 12, allowing the lamp head 13 and the lamp post 11 to be quickly pre-connected. The user can clearly understand the connection status. Subsequently, the user can fix the lamp head 13 and the lamp post 11 with screws. This pre-connection method also facilitates the user or installer to adjust the light emission of the lamp head 13, thereby adjusting the working mode of the lamp head 13 and the connection status between the lamp head 13 and the lamp post 11. This not only reduces the difficulty of subsequent installation but also improves the installation efficiency of the device. In addition, the connecting sleeve 14 is used to support the connection between the lamp head 13 and the lamp post 11, so that the lamp post 11 itself will not be subjected to the wear of the threaded connection, further improving the service life of the lamp post 11.

[0045] refer to Figures 1 to 7 The card-connecting components include:

[0046] Positioning plate 21 is fixedly connected to the lamp head 13 on the side near the lamp post 11;

[0047] Positioning seat 22 is fixedly connected to the inner wall of connecting sleeve 14. Positioning seat 22 is hinged to a locking plate 23. A locking block 24 is fixedly connected to the upper end of the locking plate 23. The locking block 24 is locked to the upper side of the positioning plate 21.

[0048] The reset plate 25 slides and abuts against the inner wall of the connecting sleeve 14, and the reset plate 25 abuts against the inclined side of the locking plate 23;

[0049] Reset post 26 is fixedly connected to the outside of connecting sleeve 14, and a reset spring 27 is sleeved on the reset post 26;

[0050] The transmission plate 28 slides and abuts against the outer wall of the connecting sleeve 14, and the two ends of the return spring 27 of the transmission plate 28 abut against the outer wall of the transmission plate 28 and the connecting sleeve 14 respectively.

[0051] Using the snap-fit ​​assembly, the user can hold the lamp head 13 at an angle and insert the positioning plate 21 into the limiting slot 12. The positioning plate 21 drives the locking block 24 to move forward. When the locking plate 23 and the reset plate 25 come into contact with each other, the snap-fit ​​assembly securely engages the positioning plate 21 in the limiting slot 12, enabling the lamp head 13 and the lamp post 11 to achieve a quick pre-connection. The user can clearly understand the connection status of the two. Subsequently, the user can fix the lamp head 13 and the lamp post 11 together with screws. This pre-connection method also facilitates the user or installer to adjust the light emission of the lamp head 13, thereby adjusting the working mode of the lamp head 13 and the connection status between the lamp head 13 and the lamp post 11. This not only reduces the difficulty of subsequent installation but also improves the installation efficiency of the device.

[0052] refer to Figures 5 to 6 The upper side of the positioning plate 21 is provided with a locking groove 211, which is inclined downward towards the positioning seat 22. The locking block 24 fits into the inner wall shape of the locking groove 211.

[0053] By tilting the slot 211, when the slot block 24 exerts downward force, it applies a force to the positioning plate 21 in the direction of the lamp post 11, so that when the lamp post 11 and the lamp head 13 are pre-connected, the two will not easily separate, thus improving the connection stability of the two.

[0054] refer to Figures 5 to 6 The positioning plate 21 has a resistance groove 212 on its lower side, and a resistance block 29 is abutted against the inner wall of the resistance groove 212. The resistance block 29 is fixedly connected to the inner wall of the connecting sleeve 14.

[0055] The force-bearing block 29 causes the positioning plate 21 to be subjected to the force of the snap-fit ​​component, enabling the positioning plate 21 to better connect with the limiting slot 12. This prevents the lamp head 13 from easily coming off the limiting slot 12, further ensuring the connection strength between the positioning plate 21 and the lamp post 11. This facilitates the user's alignment and connection adjustments. Furthermore, the beveled edge of the force-bearing block 29 allows the user to adjust the pre-connection effect between the positioning plate 21 and the lamp post 11 by applying an upward force to the end of the lamp head 13 away from the lamp post 11. This allows the positioning plate 21 to pass through the force-bearing groove 212, which has the same shape as the force-bearing block 29, making it easier for the positioning plate 21 to detach from the snap-fit ​​component. This also facilitates the user's adjustment of the connection between the lamp post 11 and the lamp head 13.

[0056] refer to Figure 1 A lamp holder 15 is fixedly connected to the side of the lamp post 11 away from the lamp head 13;

[0057] The lamp holder 15 is preferably a flat plate, which is fixedly connected to the lamp post 11 by screws and nuts. A soft material pad, such as a rubber pad, is provided on the underside of the lamp holder 15 to ensure the stability of the lamp holder 15. A slot can be opened in the middle section of the lamp holder 15 to ensure that the overall center of gravity of the device can fall completely into the lamp holder 15, so that the device can be placed stably. At the same time, the slot can reduce the weight of the lamp holder 15 itself, making it easier for users to move it. Moreover, compared with the slotless design, the slot design is also more convenient for users to identify the disassembly and assembly of the device in actual use, making it easier for users to install.

[0058] refer to Figures 1 to 3 The middle section of the lamp post 11 is equipped with a control module for controlling the light source of the lamp head 13;

[0059] The control module can be either button-type or screen-display type, allowing users to easily adjust the headlamp's lighting mode and improving the interactivity between the headlamp's lighting and the user.

[0060] Example 2

[0061] This utility model also proposes a phosphorless LED side-emitting module, referring to... Figures 1 to 7 include:

[0062] The lamp head 13 has a backlight 131 and a sidelight 132 on its upper and lower ends, respectively. The sidelight 132 includes a phosphorless LED with red and yellow light and a color temperature LED strip. A light-diffusing plate 133 is fixedly connected to both the backlight 131 and the sidelight 132 on the side of the lamp head 13. The backlight 131 and the sidelight 132 help to provide uniform illumination, making the distribution of light sources more balanced, thereby improving the overall brightness and luminous efficacy of the lamp and avoiding the problems of strong shadows or excessive local brightness. The sidelight 132 includes a phosphorless LED with red light (wavelength 630nm) and yellow light (wavelength 560nm). With color temperature LED light strips, the golden light can achieve low color temperature and high color rendering index illumination with no blue light component. Its color rendering index can exceed 80, and the color temperature range is 1600-2200K, which meets the lighting needs. It can prolong the tear film breakup time of dry eye patients, increase tear secretion in dry eye model rabbits and mice, reduce corneal fluorescein staining score, and reduce corneal and conjunctival cell apoptosis and inflammatory factor expression. It has high luminous efficacy and long service life. Combined with color temperature LEDs, the color temperature can be controlled. The golden light phosphorless LED beads and color temperature LED beads are arranged alternately on the same light strip to make the emitted light effect more uniform.

[0063] By placing the side light source 132 in the annular groove and combining it with the light doubling plate 133, the divergence angle of the light source can be effectively expanded, making the illumination of the lamp more uniform and avoiding localized overly concentrated or uneven illumination. Through the reasonable configuration of the backlight 131 and the side light source 132, combined with the design of the light doubling plate, the overall illumination effect is more uniform and comfortable, which can meet the usage needs of more scenarios.

[0064] Reference Figures 1 to 7 The lamp holder 13 includes a lamp frame 134. An annular groove is provided at the outer edge of the lamp frame 134. The side light source 132 is disposed in the annular groove. A clamping plate 135 is snapped onto the lamp frame 134 to limit the side light source 132.

[0065] The lamp frame 134 adopts a structure of annular groove and clamping plate 135. The side light source 132 is firmly clamped in the groove and limited by the clamping plate, which can ensure that the side light source is fixed and avoid loosening or displacement during use, thereby extending the service life of the lamp and enhancing the stability and reliability of the product.
