Description

Technical Field

[0001] This utility model relates to the field of lighting manufacturing, and in particular to a light fixture anti-drop head end structure and the light fixture thereof. Background Technology

[0002] In the field of lighting fixtures, the fixing method of the end lamp holder is a key part of the fixture's structural design. It directly affects the fixture's structural stability, sealing reliability, service life, and even overall safety, and has a decisive impact on the fixture's comprehensive performance.

[0003] In existing technologies, the fixing methods for end lamp holders are diverse, but all have certain limitations. For example, refer to the attached... Figure 1 As shown, in the existing structure, the end lamp holder 100 is not directly connected to the lamp body, but is indirectly connected to the lamp body through an intermediate component, the lamp plate 200. The lamp plate 200 serves as a bridge for force transmission between the end lamp holder 100 and the lamp body. The end lamp holder structure is more complex, consisting of an upper seat 101 and a lower seat 102. During fixing, screws 103 are passed sequentially through the pre-set holes in the lower seat 102 and the corresponding holes 201 on the lamp plate, and finally screwed into the groove in the upper seat 101. This assembly process fixes the end lamp holder 100 to the lamp plate 200, and the other end of the lamp plate is then fixed to the lamp body. In this structure, the lamp body, as the main load-bearing structure of the lamp, bears the overall load. The force on the end lamp holder 100 needs to be transmitted to the lamp body through the intermediate medium of the lamp plate 200. At the same time, the end lamp holder is also designed with a second fixing shaft to assist in fixing the lamp cover and enhance the stability of the cover.

[0004] In addition, there are other fixing methods in the existing technology: one is to directly screw a screw into the outer end face of the end lamp holder, and fix the end of the screw to the LED lamp board after penetrating the lamp holder. The end lamp holder is indirectly fixed by means of the connection between the LED lamp board and the lamp body.

[0005] However, these existing technologies generally have significant drawbacks. Regarding material selection, existing technologies often use structural components (such as metals with high strength) for the lamp body, while the end lamp holders are mostly made of plastic. When the lamp panel, also made of plastic, is connected to the end lamp holder, the inherent rigidity and deformation resistance of the plastic material are weak. When the lamp is subjected to common external impacts such as drops or vibrations, the end lamp holder will experience outward pulling force, causing the lamp panel to move outward away from the lamp body. This displacement directly disrupts the originally tight fit between the end lamp holder and the lamp body, gradually widening the gap between them. This widening gap severely weakens the lamp's sealing effect, allowing external dust and moisture to easily enter the lamp. This can not only affect the normal operation of internal electronic components, leading to decreased luminous performance or malfunction, but also accelerate the aging of internal components, significantly shortening the lamp's lifespan, and even potentially causing safety hazards in certain environments. Meanwhile, long-term vibration and displacement may also cause the connection structure to loosen, further aggravating the failure of the fit between the end lamp holder and the lamp body, and affecting the overall stability of the lamp. Utility Model Content

[0006] One advantage of this utility model is that it provides a lamp anti-drop head end structure and the lamp itself. The lamp anti-drop head end structure designs the head end and the outer shell as structural components. The rigid connection of the structural components makes the overall structure less prone to deformation and the connection more robust, which can effectively cope with external impacts in scenarios such as drops and vibrations.

[0007] Another advantage of this utility model is that it provides a lamp anti-drop head end structure and the lamp itself. The head end of the lamp anti-drop head end structure is directly connected to the outer shell, effectively avoiding the head end being connected through the lamp plate in the middle, which greatly reduces the impact force on the lamp plate when it falls, and further ensures the overall performance and safety of the lamp.

[0008] Another advantage of this utility model is that it provides a lamp anti-drop head end structure and the lamp itself. Since the head end of the lamp anti-drop head end structure is directly connected to the outer shell and adopts a rigid fit of structural components, it avoids the problem of the gap between the head end and the lamp body widening due to displacement under force, which significantly improves the sealing effect, reduces the risk of dust, moisture and other substances entering the lamp, and helps to extend the service life of the lamp.

[0009] Another advantage of this utility model is that it provides a lamp anti-drop head end structure and the lamp itself.

The lamp body is adapted to be inserted into the mounting groove and the shoulder is biased against the limiting wings. The side wall has at least one fixing hole, which is located at the end of the outer casing. One end portion includes an end face, two embedded plates, and a lamp body protection plate. The embedded plates are integrally mounted on both sides of the end face and are adapted to be inserted into the outer casing along the inner wall of the side wall to close the end of the outer casing. The lamp body protection plate is integrally mounted on the top of the end face, and when the embedded plates are inserted into the outer casing, the lamp body protection plate covers the end of the lamp body within the mounting groove. The embedded plates have at least one screw hole corresponding to the fixing hole. At least one fixing screw is installed in the screw hole through the fixing hole to keep the head end fixed to the housing and restrict the movement of the lamp body.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] Reference Appendix Figure 2 To be continued Figure 7 As shown in the attached diagram, the impact-resistant head end structure of the lamp and the lamp itself are illustrated. Figure 2As shown, the lamp 800 includes a main body 810 and a rotating shaft 820. One end of the rotating shaft 820 is mounted on the main body 810, and the other end of the rotating shaft 820 is mounted on the lamp's anti-drop head end structure 600. The lamp's anti-drop head end structure 600 can rotate with the rotating shaft 820 to move closer to or further away from the main body 810. The lamp's anti-drop head end structure 600 includes a head end 630, a housing 620, and a lamp body 610. The lamp's anti-drop head end structure 600 designs the head end 630 and the housing 620 as structural components. The rigid connection of the structural components makes the overall structure less prone to deformation and the connection more robust, effectively resisting external impacts such as drops and vibrations. The head end 630 is directly connected to the housing 620, effectively avoiding the head end 630 being connected through the lamp panel as an intermediate connection, greatly reducing the impact. The impact force on the lamp panel during a drop further ensures the overall performance and safety of the lamp 800. At the same time, the anti-drop head structure 600, because the head end 630 is directly connected to the outer shell 620 and adopts a rigid fit of structural components, avoids the problem of the gap between the head end 630 and the lamp body 610 widening due to displacement under force, significantly improving the sealing effect, reducing the risk of dust, moisture and other substances entering the lamp 800, and helping to extend the service life of the lamp 800.

[0034] For details, please refer to the appendix. Figure 3 To be continued Figure 7 As shown, the lamp anti-drop head end structure 600 includes the lamp body 610, the outer shell 620 and the head end 630. The lamp body 610 can be inserted into the outer shell 620 and sealed by the head end 630 to fix the lamp body 610 and restrict the relative movement of the lamp body 610 and the head end 630.

[0035] A shoulder 611 is provided on each side of the lamp body 610. The shoulder 611 is arranged along the length of the lamp body 610 and is lower than the light-emitting plane of the lamp body 610. The outer casing 620 includes a base plate 621, two side walls 622, and two limiting wings 623. The side walls 622 are integrally connected to the two sides of the base plate 621, and the limiting wings 623 are integrally connected to the edges of the side walls 622 to form a mounting groove 624 with the side walls 622 and the base plate 621. In other words, the cross-section of the outer casing 620 is similar to a C-shape, but more rectangular. The limiting wings 623 are located at the two ends of the C-shape. The limiting wings 623 tend to converge towards the mounting groove 624. The lamp body 610 is adapted to be inserted into the mounting groove 624 and the shoulder 611 is biased against the limiting wings 623 to limit the movement of the lamp body 610 within the outer casing 620, keep the lamp body 610 securely installed within the outer casing 620, and ensure that the head end of the lamp body 610 is located at the head end position of the outer casing 620.

[0036] Furthermore, the sidewall 622 has at least one fixing hole 625. In this embodiment, the number of fixing holes 625 is preferably two, and the fixing holes 625 are located at the end of the sidewall 622, that is, near the end of the lamp body 610. Each end of the sidewall 622 is provided with a fixing hole 625, and the two fixing holes 625 are preferably located on the same axis. Even further, the fixing holes 625 are preferably countersunk holes.

[0037] The head end 630 includes an end face 631, two embedded plates 632, and a lamp body protection plate 634. The embedded plates 632 are integrally mounted on both sides of the end face 631 and are adapted to be inserted into the outer shell 620 along the inner wall of the side wall 622 to close the end of the outer shell 620, that is, the end face 631 closes the end of the outer shell 620. The lamp body protection plate 634 is integrally mounted on the top of the end face 631, and when the embedded plates 632 are embedded in the outer shell 620, the lamp body protection plate 634 covers the end of the lamp body 610 in the mounting groove 624, further protecting the lamp body 610 from impacts when dropped.

[0038] The embedded plate 632 has at least one screw hole 633, which corresponds to the fixing hole 625. The lamp anti-drop head end structure 600 also includes at least one fixing screw 640. In this embodiment, the number of fixing screws 640 is preferably two. The fixing screws 640 are installed in the screw hole 633 through the fixing hole 625 to keep the head end 630 fixed to the outer shell 620, thereby limiting the movement of the lamp body 610 when subjected to external impact.

[0039] The end face 631 also has a light-transmitting hole 6311, which allows the lamp body 610 to emit light in the direction of the end face 631, so as to adapt to more usage scenarios.

[0040] Specifically, the head end 630 and the outer shell 620 are structural components, integrally manufactured using metal materials, preferably 6063 aluminum alloy. Using 6063 aluminum alloy as a structural component for the head end 630 and the outer shell 620 meets the requirements for rigid connection, effectively resisting external impacts such as drops and vibrations, reducing the risk of deformation. Simultaneously, 6063 aluminum alloy has good plasticity, is easy to cut, drill (e.g., machine screw holes), and form, facilitating the manufacture of the head end 630 and the outer shell 620 with specific connection structures (e.g., screw holes, connecting parts), reducing production and processing difficulty, and suitable for mass production. Furthermore, the 6063 aluminum alloy used for the head end 630 and the outer shell 620 can also undergo powder coating or black anodizing treatment. Through anodizing and other chemical treatments, a dense and hard oxide film can be formed. This oxide film not only improves the corrosion resistance of the head end 630 and the outer casing 620 (preventing the lamp 800 from rusting in humid environments), but also enhances surface hardness and wear resistance. Furthermore, its appearance can be optimized through coloring (such as black), balancing functionality and aesthetics. While ensuring structural strength, using 6063 aluminum alloy reduces the overall weight of the lamp 800, improving its portability, making it particularly suitable for work lights and other lighting equipment requiring mobile use.

[0041] More specifically, the head end 630 also has two steps 635, which are disposed on both sides of the lamp body protection plate 634 to connect the embedded plate 632. The steps 635 are flush with the shoulder 611. When the head end 630 is embedded in the outer shell 620, the end of the step 635 abuts against the end face of the lamp body 610. The step 635 is restricted by the limiting wing 623 to further protect the lamp body 610 from the impact. Furthermore, the length of the lamp body protection plate 634 is greater than the length of the step 635, so that when the lamp body protection plate 634 covers the lamp body 610, it can restrict the relative displacement of the lamp body 610 to a greater extent. The length of the step 635 is the same as the length of the embedded plate 632, thereby ensuring good structural stability when the head end 630 is installed at the end of the outer shell 620, making the overall structure less prone to deformation, the connection more secure, and effectively coping with external impacts in scenarios such as drops and vibrations.

[0042] Table 1 shows the drop test data for the plastic end of the lamp 800 of this utility model. The test sample size was 4 pieces. The test environment was 25℃ and 30-80% humidity. The test equipment consisted of a custom drop test bench and a cement floor. Ten sets of 40 drops each (total 400 drops) were performed on the plastic samples from a distance of 2 meters. The initial average gap was 0.3mm, and after 40 drops, the average gap was 1.53mm, with an average gap change of 1.22mm. After each drop, the metal buckle could be fastened back in place, allowing the test to continue. The device functioned normally and was deemed to meet the test standards.

The test sample size was 4 pieces. The test environment was 25℃ and 30-80% humidity. The test equipment consisted of a custom drop test bench and a cement floor. Ten sets of 40 drops each (total 400 drops) were performed on the metal samples at a height of 2 meters. (See attached table for details.) Figure 7The gap 900 shown is the gap between the lamp body protection plate 634 and the lamp body 610, and also the gap between the end face 631 and the end face of the outer shell 620. The initial average gap is 0.3mm (consistent with the initial gap of the plastic part), and after 40 drops, the average gap is 1.01mm (approximately 66% of the average size of the plastic part after the drop, which is 1.53mm, satisfying the requirement that the size of the plastic part after the drop is more than 50% larger than that of the metal part), with an average gap change of 0.71mm. After each drop, the metal buckle is reattached after being dislodged, and the test can continue. The function is normal, and it is determined to meet the test standards. In summary, the metal head end 630, through the mechanical properties of the material itself, is superior to the plastic head end in terms of deformation resistance, gap control, and structural stability. Especially in long-term impact scenarios, it can more reliably ensure the overall performance of the lamp.
