Description

TECHNICAL FIELD

[0001] The utility model relates to stage lamp technical field especially relates to a light projector of external NFC antenna. BACKGROUND

[0002] In recent years, with the rapid development of the Internet of Things technology and intelligent management, the intelligent and information level of lamp products are increasingly valued. In order to facilitate the management, maintenance and information tracing of lamps, more and more lamp products begin to use near field communication (NFC) technology. By setting NFC chip in the lamp, and storing the model, parameters, production information and other key data of the lamp in the NFC chip, users can use NFC reader to induct the lamp, and quickly read the information of the lamp, which brings great convenience to the production management, warehousing logistics, installation and maintenance of lamps.

[0003] For example, in the quality detection link before the lamp leaves the factory or when maintaining the lamp, the staff can quickly check the model and a series of parameters such as software version or working time of the lamp through the NFC reader, avoid the errors that may occur in manual checking, and also avoid the operation that the lamp needs to wait for commercial power and turn on the lamp for confirmation, improve the detection efficiency and accuracy. In the warehousing logistics link, by scanning the NFC label outside the transportation packaging box, the model and quantity of the lamps in the packaging box can be quickly understood, and intelligent management of inventory is realized. In the lamp installation and maintenance link, technicians can read the running state and fault information of the lamp on site through the NFC reader, assist fault diagnosis and maintenance, shorten the maintenance time and reduce the maintenance cost.

[0004] However, the NFC lamp scheme in the prior art still has some limitations in actual application, especially on products such as light projectors. Because the identification distance of NFC technology is short, in order to ensure that the NFC reader can effectively induct the NFC chip, the installation position of the NFC chip in the lamp is crucial.

[0005] In the prior art, in order to facilitate the reading of the NFC chip as much as possible, the NFC chip is usually set at a relatively central position of the lamp, such as the middle part of the lamp. However, the lamp usually needs to be packed for protection during transportation to avoid damage to the lamp during transportation. Because the light emitting surface of the lamp is usually made of transparent materials such as glass or acrylic, which is relatively weak in hardness compared with other parts, in order to protect the light emitting surface from being damaged, the lamp is usually assembled from the side during packing, and after packing, the light emitting surface of the lamp and the NFC chip in the middle part are usually blocked by the box plate of the packaging box, making it difficult for the NFC reader to directly induct the NFC chip, and the information reading success rate is reduced.

[0006] More inconveniently, during the transportation and handling process, the transport box with the inside floodlight will inevitably appear in various orientations, which further increases the uncertainty of the NFC chip position. When it is necessary to check the lamp model before shipment or during transportation, according to the prior art, the staff has to completely disassemble the transport box and move the lamp out of the box to find the position of the NFC chip, and then use the NFC reader to read the information. This operation method is extremely cumbersome, time-consuming and labor-intensive, and seriously affects the work efficiency.

[0007] In addition, even if the lamp is successfully installed and used, the installation form or installation angle of the lamp can be various. In some installation cases, the NFC chip position of the lamp can be blocked by the structural parts of the lamp itself or other objects in the installation environment, which also increases the difficulty of NFC information identification and reduces the user experience.

[0008] In order to solve the above NFC layout problem, some improvement schemes have been proposed in the prior art. For example, in order to expand the coverage range of the NFC signal and improve the identifiability of the NFC chip, some schemes try to increase the number of NFC chips and arrange multiple NFC chips at multiple positions such as the lamp head, the lamp holder, the two sides of the support arm, etc. of the lamp. In this way, it is expected that the NFC chip can be scanned more easily regardless of the angle of approaching the lamp. However, this scheme of increasing the number of NFC chips will undoubtedly significantly increase the manufacturing cost of the lamp, especially in the case of mass production, the cost increase is more obvious. Moreover, even if the number of NFC chips is increased, the problem of the NFC chip being blocked by the packaging box or the installation environment cannot be fundamentally solved, and only the probability of scanning the NFC chip is improved, and the effect is limited.

[0009] Therefore, how to effectively solve the problem of inconvenience in reading NFC information caused by the blocking of the NFC chip position during the packaging and transportation and installation and use of the floodlight and other lamp products without significantly increasing the manufacturing cost has become a technical problem to be solved by those skilled in the art.

[0037] As Figs. 1 to 3 shown, the structure of the projection lamp with external NFC antenna of the embodiment is mainly composed of lamp holder 1, support arm 2 and base 3. Among them, the base 3 is used as the support structure of the projection lamp, for ensuring the stable placement of the whole projection lamp, the support arm 2 is fixedly arranged on the base 3, and plays the role of connecting and supporting the lamp holder 1, the lamp holder 1 is the core lighting component of the projection lamp, and at least one side of the length direction of the lamp holder 1 is connected with the support arm 2 through the hinge structure, the hinge mode makes the lamp holder 1 can be angle adjusted relative to the support arm 2, so as to realize the flexible adjustment of the lighting direction. A plurality of lamp beads 4 are arranged in the lamp holder 1, and the lamp beads 4 are arranged in matrix on the light emitting side, and the matrix arrangement can make the light emitted by the lamp beads 4 uniformly distributed, form uniform and high brightness lighting effect, and meet the lighting demand of the projection lamp.

[0038] In order to realize the convenient reading of the lamp information, the projection lamp further comprises an NFC chip and an NFC antenna. The NFC antenna 5 is electrically connected with the NFC chip, and the NFC antenna 5 and the NFC chip are connected with each other through the plug and the socket. The NFC chip serves as an information storage unit and pre-stores various parameter information of the projection lamp, such as lamp model, power, production date, etc. The NFC chip is arranged in the interior of the projection lamp, for example, can be arranged in the interior space of the lamp head 1, the support arm 2 or the base 3, to realize effective protection of the NFC chip. In addition, the embodiment adopts an external NFC antenna 5. The NFC antenna 5 is not directly connected with the NFC chip, but performs non-contact data interaction with the NFC chip through magnetic field coupling technology. More importantly, the NFC antenna 5 is innovatively arranged on the support arm 2. The support arm 2 is usually located at a relatively outer position in the structure of the projection lamp. Even after the projection lamp is loaded into a transport box, the side surface of the support arm 2 is relatively easy to touch, which creates a convenient condition for external induction of the NFC antenna 5.

[0039] In one embodiment, the projection lamp structure of the embodiment further comprises an antenna circuit board which is detachably embedded on one side of the support arm 2, and the NFC antenna 5 is integrated on the antenna circuit board 5. It can be understood that, first, the detachable embedded design significantly improves the maintainability of the product. When the NFC antenna 5 fails, it is not necessary to disassemble the entire projection lamp. Only the antenna circuit board needs to be detached from the support arm 2 for replacement or repair, which greatly simplifies the maintenance process and reduces the maintenance cost and time. Second, the antenna circuit board as an independent component provides greater flexibility for the selection and optimization of the NFC antenna 5. Designers can select antenna circuit boards of different materials, sizes and shapes according to actual application scenarios and performance requirements, as well as NFC antennas 5 integrated thereon, so as to optimize the performance of NFC communication, such as increasing the reading distance, enhancing the signal stability, etc. Third, the embedded structure helps to realize the structural integration of the NFC antenna 5 and the support arm 2, and keep the overall appearance of the projection lamp simple and beautiful. The embedded mode can adopt buckles, screws and other forms to ensure that the NFC antenna 5 is firmly fixed on the support arm 2.

[0040] In one embodiment, the mounting hole 6 is provided on the support arm 2, and the mounting box 7 is detachably sleeved in the mounting hole 6, and the NFC antenna 5 is accommodated and connected inside the mounting box 7.

Secondly, the mounting box 7 can protect the antenna circuit board and the NFC antenna 5. The shell of the mounting box 7 can be made of a material with certain strength, which can effectively prevent the NFC antenna 5 from being affected by external impact, extrusion, dust, moisture and other environmental factors, thereby improving the reliability and service life of the NFC antenna system. Moreover, the detachable mounting box 7 further enhances the convenience of maintenance. When the NFC antenna 5 needs to be replaced, the mounting box 7 can be directly taken out of the mounting hole 6 without the need to disassemble the internal structure of the support arm 2, thereby making the maintenance operation more simple and fast.

[0041] In one embodiment, the mounting box 7 includes a cover 8 shielding the antenna circuit board from the inside of the support arm 2 to the outside of the support arm 2. It can be understood that the cover 8 as a component part of the mounting box 7 further enhances the protection capability of the antenna circuit board, especially in the case of exposure outside the support arm 2, the cover 8 can effectively block the direct impact, scratching, dust, rain and other external factors, thereby providing more comprehensive environmental protection for the NFC antenna system and improving its reliability in various harsh working conditions.

[0042] In one embodiment, the mounting box 7 has a limiting step 9 around the outer edge, and when the mounting box 7 is sleeved in the mounting hole 6 from the inside of the support arm 2 to the outside of the support arm 2, the limiting step 9 is clamped on the periphery of the mounting hole 6 from the inside of the support arm 2. It can be understood that the limiting step 9 realizes the accurate positioning of the mounting box 7 in the mounting hole 6. When the mounting box 7 is inserted into the mounting hole 6 from the inside of the support arm 2, the limiting step 9 will be clamped with the outer edge of the mounting hole 6, limiting the mounting box 7 from moving outward, thereby ensuring the accurate and reliable position of the mounting box 7 in the mounting hole 6, avoiding the situation of too deep or too shallow installation, and ensuring the accuracy of the installation position and direction of the NFC antenna 5, which is conducive to the stable transmission and reading of the NFC signal.

[0043] In one embodiment, the limiting step 9 is partially protruding and forms a screw seat 10, which corresponds to the screw position formed in the inner side of the support arm 2 and is connected by a screw. It can be understood that the screw seat 10 and the screw connection provide a reliable mechanical fixing method, which ensures that the mounting box 7 is firmly fixed on the support arm 2, preventing the mounting box 7 from loosening or falling off during use, especially in the case of vibration or impact of the light, the threaded connection can provide more stable fixing effect, improve the reliability and safety of the NFC antenna system. At the same time, the screw connection also ensures the detachability of the mounting box 7, which is convenient for subsequent maintenance and replacement.

[0044] In one embodiment, the NFC antenna 5 is pasted / connected / screwed to the mounting box 7. It can be understood that various connection methods provide flexibility in design and manufacturing. According to different product requirements, cost considerations and assembly process, the appropriate connection method can be selected to fix the NFC antenna 5 in the mounting box 7. For example, the pasting method is suitable for occasions with high requirements for waterproof and dustproof, the connection method is suitable for quick assembly scenes, and the threaded connection is suitable for occasions that require more secure connection. The selection of various connection methods provides greater freedom for product design and can meet the needs of different application scenarios.

[0045] In one embodiment, the NFC antenna 5 is arranged near the pivot shaft of the support arm 2. It can be understood that arranging the NFC antenna 5 near the pivot shaft of the support arm 2 can improve the identification efficiency and convenience of the NFC antenna. Since the support arm 2 is usually located on the side of the light, and the position near the pivot shaft is relatively open and not easily blocked by the lamp head 1 or other components, arranging the NFC antenna 5 in this position can facilitate the NFC reader to approach and interact with data, especially in the case of light box transportation or limited installation angle, it is still relatively easy to access the NFC antenna 5, improving the reading efficiency of the NFC chip information and user experience.

[0046] In one embodiment, the NFC chip can be installed in the lamp head 1 / support arm 2 / base 3. It can be understood that various installation positions of the NFC chip can facilitate greater flexibility in product design. According to the specific structure of the light, the internal space layout, and the consideration of heat dissipation, protection, etc., the NFC chip can be flexibly arranged in a suitable position of the lamp head 1, support arm 2 or base 3 without being limited to a specific installation position, thereby better adapting to different product design requirements and optimizing the working performance and reliability of the NFC chip.

[0047] In one embodiment, the support arm 2 and the base 3 are provided as an integrated structure. It can be understood that the integrated structure simplifies the structure and assembly of the projection lamp. Integrating the support arm 2 and the base 3 reduces the number of components, lowers the production cost, simplifies the assembly process, and improves the production efficiency. At the same time, the integrated structure generally improves the overall strength and stability of the structure, enhances the structural reliability and impact resistance of the projection lamp.
