Technical Field
[0001] The utility model relates to the field of lamps, and particularly relates to a solder-free lamp housing. Background Art
[0002] Ceiling lamps are a common type of lighting fixture in daily life. They can be installed on the ceiling for indoor lighting. Specifically, ceiling lamps are installed on the ceiling to irradiate the generated light downward or along a specified light path into the environment, so that the target environment can be evenly illuminated to obtain a good lighting effect. And because of their unique installation method, they do not need to occupy floor space, so they are deeply favored by consumers. Generally, according to the installation method of ceiling lamps, they can be divided into many types such as ceiling lights, chandeliers, wall lights, track lights, and downlights. Among them, downlights are installed in a way that is embedded in the ceiling, and compared with other ceiling lamps, they can occupy less space on the ceiling, meeting the current simple aesthetic trend.
[0003] However, existing downlights all need to adopt iron stamping and go through process steps such as welding and turning to be formed. The forming process is complex and the production efficiency is low. Specifically, referring to Figures 1A to 1B , an existing downlight is shown. The downlight includes an iron outer cylinder ring 10P and an iron inner ring 20P. The iron inner ring 20P is installed on the iron outer cylinder ring 10P to fix the corresponding light source. The iron outer cylinder ring 10P includes an iron straight cylinder 11P and a screen surface ring 12P. The screen surface ring 12P is arranged at the lower end of the iron straight cylinder 11P. A groove ring 13P for installing the iron inner ring 20P is arranged on the inner wall of the iron straight cylinder 11P. Due to the special structure and angle between the iron straight cylinder 11P and the screen surface ring 12P, the structural and positional relationship between the iron straight cylinder 11P and the screen surface ring 12P cannot be integrally formed by the iron stamping process. After the iron straight cylinder 11P and the screen surface ring 12P are respectively stamped, the screen surface ring 12P needs to be welded to the lower end of the iron straight cylinder 11P through subsequent welding processing. At the same time, the iron stamping process cannot directly stamp the groove ring 13P on the inner wall of the iron straight cylinder 11P. Only after the iron straight cylinder 11P is stamped and formed, the groove ring 13P can be formed on the inner wall of the iron straight cylinder 11P by turning, or the groove ring 13P can be formed by welding an iron piece to the inner wall of the iron straight cylinder 11P. That is to say, the forming process of the iron outer cylinder ring 10P is very complex, and it needs to go through multiple steps to be formed, and manual operation is required, resulting in high production cost and low efficiency, and affecting the consistency of mass production of products.

[0039] It will be understood that the term "a" should be construed as "at least one" or "one or more". That is, in one embodiment, the number of an element may be one, while in other embodiments, the number of the element may be multiple. The term "a" should not be construed as a limitation on the number.
[0040] The present utility model provides a solder-free lamp housing. The structural design of the solder-free lamp housing enables the solder-free lamp housing to avoid the soldering step during the production process and be formed, which is beneficial to improving production efficiency and reducing production costs.
[0041] Specifically, referring to the accompanying drawings of the specification of the present utility model Figures 2 to 10 , the solder-free lamp housing 100 according to an embodiment of the present utility model is schematically shown. The solder-free lamp housing 100 includes an integrally formed outer cylinder 10 and an inner ring 20. The structural design of the integrally formed outer cylinder 10 enables the integrally formed outer cylinder 10 to be integrally stamped and formed without using the soldering step. The integrally formed outer cylinder 10 includes a frustum cylinder 11 and a face ring 12 integrally formed at the lower end of the frustum cylinder 11. The radius of the upper end of the frustum cylinder 11 is smaller than the radius of the lower end, so that the barrel wall of the frustum cylinder 11 can form an inclined surface, which is convenient for stamping and forming with the face ring 12.
[0042] Preferably, the face ring 12 extends upward and outward first from the lower end of the frustum cylinder 11 and then extends outward, so that a bent arc angle design is formed at the lower end of the integrally formed outer cylinder 10, which is convenient for the integrally formed outer cylinder 10 to be integrally stamped and formed.
[0043] Furthermore, the inner ring 20 has at least one protruding mounting portion. The inner ring 20 is mounted on the integrally formed outer cylinder 10 based on the mounting portion, so that there is no need to additionally provide a concave ring groove for mounting the inner ring 20 inside the integrally formed outer cylinder 10, enabling the integrally formed outer cylinder 10 to be directly formed in the stamping process, effectively improving production efficiency and reducing production costs.
[0044] Specific reference is made to Figures 2 to 5, an embodiment of the solderless lamp housing 100 is illustrated, wherein the inner ring 20 includes an inner cylinder 21 and an inner edge ring 22. The inner cylinder 21 has a straight cylinder section 212 and an insertion section 213 formed at the lower end of the straight cylinder section 212. The mounting portion protrudes outward from the straight cylinder section 212. The inner edge ring 22 has an outer edge 222 and an inner edge 223 facing the same direction as the outer edge 222. The inner edge ring 22 extends from the outer edge 222 towards the central axis of the inner ring 20 and is bent to form a state where the outer edge 222 and the inner edge 223 face the same direction, and an insertion gap 221 is formed based on the bending of the inner edge ring 22. The inner cylinder 21 is riveted to the inner edge ring 22 with the insertion section 213 inserted into the insertion gap 221, thereby forming the inner ring without welding.
[0045] Further, the inner ring 20 further includes an inner built-in cylinder 23. At least two outwardly protruding latches 231 are provided on the outer sidewall of the inner built-in cylinder 23 to form the mounting portion, and at least two inwardly protruding latches 232 are provided on the inner sidewall of the inner built-in cylinder 23. The corresponding light source can be installed and fixed in the inner built-in cylinder 23 by the inwardly protruding latches 232. At least two snap button outlets 211 matching the outwardly protruding latches 231 are provided on the straight cylinder section 21. The inner built-in cylinder 23 is installed in the inner cylinder 21 with the outwardly protruding latches 231 protruding from the snap button outlets 211. Thus, when the inner ring 20 is installed in the integrally formed outer cylinder 10, the inner ring 20 can be limited in the integrally formed outer cylinder 10 based on the outwardly protruding latches 231 abutting against the integrally formed outer cylinder 10. In this way, the solderless lamp housing 100 can be assembled under a solderless structural design.
[0046] Further, the integrally formed outer cylinder 10 extends from the upper end of the frustum cylinder 11 to have a mounting ring 13. The radius of the mounting ring 13 is less than or equal to the radius of the upper end of the frustum cylinder 11 to facilitate the integral stamping of the integrally formed outer cylinder 10. The inner ring 20 is installed into the integrally formed outer cylinder 10 from bottom to top. The inner edge ring 12 abuts against the upper end of the frustum cylinder 11, and the outwardly protruding latches 231 abut against the mounting ring 13. Thus, the installation of the inner ring 20 is formed, and the formation of the solderless lamp housing 100 can still be achieved without welding.
[0047] In particular, the solderless lamp housing 100 further includes a fireproof expansion ring 30, which is placed inside the inner ring 20. In case of a fire, the fireproof expansion ring 30 expands when heated to form a dense carbide to block the through hole defined by the inner ring 20, thereby isolating the upper and lower spaces of the solderless lamp housing 100 to prevent the spread of fire between the upper and lower spaces through the solderless lamp housing 100.
[0048] It is worth mentioning that the solderless lamp housing 100 further includes a light-transmitting sheet 40, which is disposed inside the inner ring 20 to form a light-transmitting closure of the through hole defined by the inner ring 20, facilitating the formation of a closed protection for the corresponding light source module. In some embodiments, based on the parameter settings of the light-transmitting sheet 40, such as light transmittance, color, etc., the lighting effect of the corresponding lamp can be changed. The present utility model places no restrictions on this.
[0049] In particular, the solderless lamp housing 100 further includes an elastic ring 50, which is placed above the insertion section 213, and the light-transmitting sheet 40 is disposed above the elastic ring 50.

On the other hand, the elastic ring 50 can also form a space below the light-transmitting sheet 40 in the inner ring 20, facilitating the user to apply force to the inner ring 20 to disassemble or install the inner ring 20.
[0050] Further, with detailed reference to Figure 5 , the built-in cylinder 23 is disposed above the light-transmitting sheet 40, and the light-transmitting sheet 40 and the elastic ring 50 can be pressed between the built-in cylinder 23 and the insertion section 213 based on the built-in cylinder 23, realizing the fixation of the light-transmitting sheet 40 and the elastic ring 50 and making the light-transmitting sheet 40 and the elastic ring 50 closely cooperate, which is beneficial to the dustproof and waterproof design of the solderless lamp housing 100.
[0051] It is worth mentioning that, with reference to Figure 5 , a lamp cup 200 is embedded in the built-in cylinder 23 and fixed by the inner convex buckle 232, and thus is fixed above the light-transmitting sheet 40, wherein the light-emitting path of the lamp cup 200 faces the light-transmitting sheet 40 so as to be able to radiate light downward through the light-transmitting sheet 40.
[0052] Further referring to Figure 6 and Figure 7, another embodiment of the solderless lamp housing 100 is illustrated, wherein the inner ring 20 also includes the inner cylinder 21 and the inner edge ring 22. The inner ring 20 extends outwardly convex from the straight cylinder section 211 in a direction away from the central axis of the inner ring 20 and has at least two protruding portions 24 to form the mounting portion. The integrally formed outer cylinder 10 extends from the upper end of the frustum cylinder 11 and has at least two arc edges 14. The radius of the arc edge 14 is less than or equal to the radius of the upper end of the frustum cylinder 11, and the radius of the arc edge 14 is less than the straight-line distance between the outer edge of the protruding portion 24 and the central axis of the inner ring 20. The inner ring 20 is installed into the integrally formed outer cylinder 10 from bottom to top. The protruding portion 24 passes through the arc edge 14 between each arc edge 14, and the inner ring 20 is rotated so that the protruding portion 24 abuts against the upper end of the arc edge 14. The inner edge ring 22 abuts against the upper end of the frustum cylinder 11, so as to form the installation of the inner ring 20, thereby enabling the formation of the solderless lamp housing 100 without soldering.
[0053] It is worth mentioning that the inner ring 20 extends upward from the upper end of the straight cylinder section 211 and has a mounting wall 25. The mounting wall 25 is provided with a mounting hole 251. The solderless lamp housing 100 further includes a lamp cup retaining ring 60. The lamp cup retaining ring 60 is installed on the mounting wall 25 by corresponding rivets or buckles passing through the mounting hole 251 for fixing the corresponding light source.
[0054] Particularly, in this structure, the solderless lamp housing 100 is also suitable for arranging the fireproof expansion ring 30 to form a corresponding fireproof design.
[0055] It is worth mentioning that in this structure, the solderless lamp housing 100 is also suitable for arranging the light-transmitting sheet 40 and the elastic ring 50.

[0056] Particularly, the integrally formed outer cylinder 10 also extends from the upper end of the frustum cylinder 11 and has two spring clip fixing walls 15 to be suitable for installing corresponding torsion springs. In this structure, the number of the arc edges 14 is two, and the two spring clip fixing walls 15 are located between the two arc edges 14. The radius of the spring clip fixing wall 15 is greater than the radius of the arc edge 14 to facilitate the protruding portion 24 passing through the arc edge 14 from bottom to top.
[0057] Further reference is made to Figure 8 and Figure 9 in which another embodiment of the solderless lamp housing 100 is illustrated, wherein the inner ring 20 also includes the inner cylinder 21 and the inner edge ring 22, wherein the inner ring 20 extends upward from the upper end of the straight cylinder section 211 to have at least two mounting arms 26 to form the mounting portion, wherein the upper end of the mounting arm 26 has an outwardly protruding cap 261, wherein the integrally formed outer cylinder 10 extends from the upper end of the frustum cylinder 11 to have a mounting ring 13, wherein the mounting ring 13 has at least two insertion positions 131 matching the mounting arms 26, and hole positions 132 on both sides of the insertion positions 131, wherein the inner ring 20 is fitted into the integrally formed outer cylinder 10 from bottom to top, and the mounting arms 26 are inserted into the insertion positions 131, wherein the solderless lamp housing 100 further includes a mounting assembly 80, wherein the mounting assembly 80 includes a switch member 82 and a switch fixing member 81, wherein the switch member 82 has a clamping buckle 821 matching the outwardly protruding cap 261, so as to be clamped by the clamping buckle 821 in the state where the outwardly protruding cap 261 is pushed upward from bottom to top into the clamping buckle 821, and the clamping buckle 821 is disengaged in the state where the outwardly protruding cap 261 is pushed upward again, wherein the switch member 82 is mounted on the switch fixing member 81, wherein the switch fixing member 81 has hole position docking portions 811 extending to both sides and through holes 8111 matching the hole positions 132 located at the hole position docking portions 811, so that the switch fixing member 81 can be fixed to above the insertion positions 131 by corresponding rivets, so that in the state where the inner ring 20 is fitted into the integrally formed outer cylinder 10 from bottom to top, the outwardly protruding cap 261 is pushed upward from bottom to top into the clamping buckle 821 and locked, thus forming the installation of the inner ring 20, so that the formation of the solderless lamp housing 100 can still be realized without soldering.
