Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lighting lamps and lanterns, especially to a lamp structure. BACKGROUND

[0002] In the field of lighting technology, bulb type lamps and lanterns are widely used in various scenes such as family residence, commercial office, outdoor emergency, etc. due to the advantages of convenient installation, direct lighting effect, etc. To meet the demand for improving the lighting brightness and range in different scenes, the mainstream bulb type lamps and lanterns usually adopt a multi-bulb combination design scheme, the core structure of which includes an integrally formed lamp body and a plurality of connecting arms extending peripherally or axially on the outer circumference of the lamp body. The free end of each connecting arm is provided with an internal thread interface, and the bulb is detachably connected with the connecting arm through the external thread on the outer circumference, and the lighting performance is strengthened through the cooperative lighting of multiple bulbs to ensure the uniformity and coverage of the brightness in the lighting area.

[0003] Although the bulb type lamps and lanterns with the above multi-bulb structure can basically meet the basic lighting needs, the inherent defects in the structural design result in many inconveniences in the production, transportation and actual use process, limiting the market adaptability and user experience of the product. Specifically, the connecting arms and the lamp body of the bulb type lamps and lanterns in the prior art are generally made by injection molding integral forming process, and the connecting arms remain in a fixed extension posture once formed, and cannot be folded or stored relative to the main body. This fixed structure will cause significant problems in the product delivery and transportation link: due to the non-foldable nature of the connecting arms, the overall lamp will occupy a large space volume, which not only significantly reduces the loading quantity in a single packaging container, but also requires the use of thicker buffer protection materials to avoid damage to the connecting arms during transportation, directly leading to a significant increase in logistics transportation costs, and also increasing the space occupation cost in the warehousing link.

[0004] On the other hand, in actual application scenarios, users often encounter the need to temporarily expand the lighting range or improve the local lighting intensity, such as large outdoor activities, temporary construction areas, etc., which often require higher power lighting support. However, the existing bulb type lamps and lanterns are all independent use units, and no connecting structure is provided in the structural design for stable assembly between multiple lamps and lanterns, so that users cannot flexibly expand the lighting capacity by combining and assembling two or more bulb type lamps and lanterns. If the above high-intensity lighting needs are to be met, users can only purchase special high-power lighting equipment, which not only increases the user's use cost, but also reduces the use flexibility and scene adaptability of the product.

[0005] In summary, the existing bulb type lamp with multi-connecting arm structure has high transportation cost due to the integrated design of the connecting arm and the main body, and lacks multi-lamp assembly function, and the structure design still needs to be further optimized and improved to solve the above-mentioned practical application problems. Utility model content

In the product delivery and storage link, all the connecting arms can be turned to the folded position, so that the connecting arms are closely attached to the main body, and the space occupation volume of the lamp as a whole is significantly reduced. This design not only increases the number of lamps loaded in a single packaging container, but also reduces the amount of buffer protection material used, reduces the logistics transportation cost from the aspects of loading efficiency and packaging cost, saves storage space, and improves the efficiency of warehouse management.

[0021] Meanwhile, when the connecting arm is turned to the unfolded position, part of the structure abuts against the main body to form reliable limiting constraint, which can firmly keep the connecting arm in the preset unfolded posture, avoiding the problem of illumination angle deviation or unstable illumination effect caused by the shaking of the connecting arm during the working process of the lamp.

Through this modular assembly method, the user does not need to additionally purchase high-power lighting equipment, but only needs to use the existing lamps to flexibly expand the lighting capacity, which not only reduces the use cost of the user, but also greatly improves the scene adaptability and use flexibility of the lamp.

[0031] The utility model will be further described below in combination with the drawings and examples.

[0032] Referring to Figures 1-8 A lamp structure comprises a main body 10, a bulb 20 and a connecting arm 30, the connecting arm 30 is rotationally connected with the main body 10 at one end close to the main body 10 to realize position switching between the folded position and the unfolded position; when the connecting arm 30 is turned to the unfolded position, part of the connecting arm 30 abuts against the main body 10, thereby restricting the connecting arm 30 to remain in the unfolded position; the bulb 20 is installed at one end of the connecting arm 30 away from the main body 10.

[0033] The lamp structure is designed based on the mechanical characteristics and mechanical limiting principle, and the folding and unfolding operation is convenient and the unfolded state is stable, and the specific use principle is as follows:

[0034] During the storage and transportation of the lamp, the user can realize structure folding by turning the connecting arm 30 upward. Since the one end of the connecting arm 30 close to the main body 10 is rotationally connected with the main body 10, the upward external force can drive the connecting arm 30 to turn upward around the rotation node until the connecting arm 30 is entirely attached to the outer circumferential surface of the main body 10, at this time, the connecting arm 30 is in the folded position, and the overall volume of the lamp is minimized, which is convenient for packaging, stacking and transportation, and effectively avoids the problem of large volume of the traditional fixed structure.

[0035] When the lamp is needed to be used, the user only needs to exert a downward overturning external force on the connecting arm 30 in the folded position, and the connecting arm 30 will be turned downward around the rotating node to switch to the unfolded position. During this process, two key designs jointly ensure the reliability of the unfolded state: on the one hand, when the lamp is working, the connecting arm 30 and the bulb 20 mounted at the end thereof will be subjected to vertical downward gravity, which will generate a downward moment around the rotating node on the connecting arm 30, so that the connecting arm 30 always has a motion trend of keeping unfolded downward, forming a gravity self-stabilizing effect, and without additional locking structure, the unfolded posture can be preliminarily maintained; on the other hand, when the connecting arm 30 is overturned downward to a preset angle, the part of the structure close to the main body 10 will form a close abutment with the corresponding limiting surface of the main body 10, and the abutment structure will generate an upward reaction force on the connecting arm 30, accurately restricting the maximum angle of the downward turning of the connecting arm 30, avoiding that it deviates from the preset lighting angle due to excessive overturning by gravity.

[0036] Through the dual effects of gravity self-stabilization and mechanical abutment limiting, the connecting arm 30 can be stably kept in the unfolded position, ensuring that the bulb 20 is always in the preset lighting orientation, and ensuring the stability of the lighting effect. The whole process does not need to rely on tools, and only through simple upward or downward overturning operation, the switching between folding and unfolding can be completed, fully taking into account the operation convenience and use reliability.
