Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lamps, and specifically, to a directional lighting lamp, and a lighting system provided with the above directional lighting lamp. Background Art
[0002] Directional lighting lamps generally refer to lamps such as downlights and spotlights. As Figure 1 shown, the existing directional lighting lamp 9 generally includes components such as a lamp body 91, a light source assembly 92, a lens 93, and an anti-glare ring 94. During assembly, the light source assembly 92 is installed at the bottom of the lamp cavity of the lamp body 91, the lens 93 is placed in the lamp cavity, and positioning feet 931 are provided on the lens 93 to be cooperatively connected with positioning holes 921 on the light source assembly 92. At least a part of the anti-glare ring 94 is located in the lamp cavity, and the anti-glare ring 94 is located at the open end of the lamp cavity and connected to the lamp body 91. After the anti-glare ring 94 is assembled with the lamp body 91, the anti-glare ring 94 needs to be pressed tightly on the lens 93 to cooperate with the positioning feet 931 on the lens 93 and the positioning holes 921 on the light source assembly 92 to limit the lens 93 in the depth direction and the radial direction of the lamp cavity, thereby preventing the lens 93 from moving in the lamp cavity. However, the existing directional lighting lamp 9 has the following deficiencies:
[0003] First, due to the structural limitation of the lens 93, the size of the positioning feet 931 is small, resulting in difficult alignment during assembly on the production line. During the assembly process, if the lamp body 91 and / or the lens 93 move slightly, the positioning feet 931 will be disengaged from the positioning holes 921 on the light source assembly 92.
[0004] Second, after assembly, the lamp body 91, the light source assembly 92, the lens 93, and the anti-glare ring 94 are stacked and fixed in sequence in the depth direction of the lamp cavity, that is, the light source assembly 92 is installed on the lamp body 91, and the lens 93 is pressed and fixed on the light source assembly 93 by relying on the anti-glare ring 94. Therefore, the tolerance requirements are very high, resulting in easy loosening of the lens 93 due to cumulative tolerance, or inability to assemble the lamp body 91, the light source assembly 92, the lens 93, and the anti-glare ring 94 due to excessive cumulative tolerance. Summary of the Invention
[0005] In order to solve the above problems, the main purpose of the utility model is to provide a directional lighting lamp that is convenient for assembly on the production line and is not affected by cumulative tolerance.

[0033] Embodiment of the Directional Lighting Fixture
[0034] Refer to Figure 2 and Figure 3, the directional lighting fixture 100 includes a lamp body 1, a light source assembly 2, a fixing base 3, a lens 4, and an anti-glare ring 5.
[0035] The lamp body 1 has a lamp cavity 11. The light source assembly 2 is installed at the bottom of the lamp cavity 11, and the light-emitting end of the light source assembly 2 faces the opening of the lamp cavity 11. Preferably, the lamp body 1 is made of aluminum alloy to ensure that the lamp body 1 has sufficient strength and corrosion resistance, and can effectively dissipate heat from the light source assembly 2, enabling the light source assembly 2 to work normally and stably.
[0036] Combined with Figure 4 and Figure 5 , the fixing base 3 has a receiving cavity 31 and an installation opening 32.

This design can ensure that the fixing base 3 has sufficient strength to be assembled with the lamp body 1 and the lens 4, simplify the structure of the fixing base 3 as much as possible while meeting the usage requirements, thereby simplifying the structure of the injection mold for forming the fixing base 3, and ensuring the structural rationality of the fixing base 3; among them, the receiving cavity 31 can be used to receive part of the lens 4. The installation opening 32 is located at the bottom of the receiving cavity 31, and the installation opening 32 penetrates the fixing base 3 in the depth direction of the lamp cavity 11, so that the light emitted by the light source assembly 2 can pass through the installation opening 32.
[0037] The lens 4 is in a frustum-like shape, and the lens 4 is installed on the fixing base 3 to be installed on the lamp body 1 through the fixing base 3. When the lens 4 is installed into the lamp cavity 11 together with the fixing base 3, the small-diameter end of the lens 4 faces the light-emitting end of the light source assembly 2.
[0038] In this embodiment, a first limiting rib 33 and a first buckle 34 are provided at the installation opening 32, such that a first clamping position is formed among the installation opening 32, the first limiting rib 33 and the first buckle 34; correspondingly, a first annular protrusion 41 is provided on the outer periphery of the lens 4, so that when the lens 4 and the fixed seat 3 are assembled, the first annular protrusion 41 is clamped within the first clamping position, and the first annular protrusion 41 is respectively adjacent to the first limiting rib 33 and the first claw portion 341 of the first buckle 34 in the depth direction of the lamp cavity 11, realizing the fixation and positioning of the lens 4 in the depth direction.

When the fixed seat 3 and the lamp body 1 are assembled, the second screw 6 is passed through the first connection hole 361 and then threadedly connected with the second connection hole. By using the second screw 6 to fix the fixed seat 3 and the lamp body 1, the firmness of the connection between the fixed seat 3 and the lamp body 1 can be effectively ensured, and the installation position accuracy of the lens 4 can be effectively ensured.
[0040] Preferably, an avoidance opening 35 is recessed inwards from the side wall of the fixed seat 3 into the accommodation cavity 31, and the avoidance opening 35 penetrates the fixed seat 3 in the depth direction of the lamp cavity 11. A partition 36 is provided at one end of the avoidance opening 35 close to the bottom of the lamp cavity 11, and the first connection hole 361 is formed on the partition 36 and penetrates the partition 36. This design can reasonably reduce the space occupied during the assembly of the fixed seat 3, is beneficial to the miniaturization design of the lamp body 1 and the directional lighting fixture 100, and reduces the production cost (because accessories such as the lamp body 1 and the anti-glare ring 5 can be made smaller, thus saving more production materials).
[0041] The anti-glare ring 5 is installed on the lamp body 1 and located at the open end of the lamp cavity 11, and at least a part of the anti-glare ring 5 is located inside the lamp cavity 11; in this embodiment, the anti-glare ring 5 is entirely located inside the lamp cavity 11 to enhance the aesthetics of the directional lighting fixture 100 and reduce the volume of the directional lighting fixture 100. Combining Figure 7 , the lamp body 1 is provided with a first annular groove 12 at the open end of the lamp cavity 11.

Among them, a second annular protrusion 14 is formed between the first annular groove 12 and the second annular groove 13; a third annular protrusion 51 is formed on the outer periphery of the end of the anti-glare ring 5 away from the fixed seat 3, and a second buckle 52 is formed on the outer periphery of the anti-glare ring 5. A second clamping position is formed between the second buckle 52 and the third annular protrusion 51. When assembling the anti-glare ring 5 and the lamp body 1, insert the anti-glare ring 5 into the lamp cavity 11 of the lamp body 1, so that the second annular protrusion 14 is engaged in the second clamping position, and the second annular protrusion 14 is adjacent to the second claw 521 of the second buckle 52 and the third annular protrusion 51 respectively. At this time, the second claw 521 is also buckled in the second annular groove 13. This design makes the assembly between the anti-glare ring 5 and the lamp body 1 more convenient and easy to operate, which is beneficial to improving the assembly efficiency of the directional lighting fixture 100.
[0042] Preferably, a second limiting rib 37 is provided at the end of the fixed seat 3 facing the anti-glare ring 5, and a third limiting rib 53 is provided at the end of the anti-glare ring 5 close to the fixed seat 3; among them, the second limiting rib 37 is preferably in the form of a first ring body, and the third limiting rib 53 is preferably in the form of a second ring body, so that when the anti-glare ring 5 is assembled with the lamp body 1, the first ring body is sleeved outside the second ring body, or the second ring body is sleeved outside the first ring body. The third limiting rib 53 is used to cooperate with the second limiting rib 37 to limit the movement of the anti-glare ring 5 in the radial direction of the second annular protrusion 14. Further, a fourth limiting rib 54 is also provided on the outer periphery of the anti-glare ring 5. After the anti-glare ring 5 is installed on the lamp body 1, the second annular protrusion 14 is arranged around the outer periphery of the fourth limiting rib 54. The above design is beneficial during the assembly process of the anti-glare ring 5 and the lamp body 1
[0043] By the cooperation of the fourth limiting rib 54 and the second annular protrusion 14, and the quota of the second limiting rib 37 and the third limiting rib 53 to limit and guide the installation of the anti-glare ring 5, so as to ensure that the second annular protrusion 14 is accurately engaged in the second clamping position, and the second claw 521 of the second buckle 52 is buckled onto the second annular protrusion 14 (inside the second annular groove 13).
[0044] When assembling the lamp body 1, the light source assembly 2, the lens 4 and the anti-glare ring 5, first install the light source assembly 2 into the lamp cavity 11 of the lamp body 1, and first install the lens 4 onto the fixed seat 3, so that the lens 4 and the fixed seat 3 form a module (such as Figure 6as shown); then, place the fixing base 3 together with the lens 4 into the lamp cavity 11, and fix the fixing base 3 and the lamp body 1 with the second screw 6; finally, insert the anti-glare ring 5 into the lamp cavity 11 so that the second annular protrusion 14 is engaged into the second clamping position, thereby completing the assembly of the lamp body 1, the light source assembly 2, the lens 4 and the anti-glare ring 5.
[0045] Since the fixing base 3 is provided for assembling the lens 4, there is no need to provide positioning feet on the lens 4 and no need to provide positioning holes on the light source assembly 2. Therefore, there is no problem of alignment between the positioning feet and the positioning holes during the assembly process, and there is no need to worry about the problems of position deviation and misalignment of the lens 4 during the assembly process. There is no assembly tolerance between the lens 4 and the light source assembly 2; moreover, when the fixing base 3 and the lamp body 1 are assembled, the lens 4 is also assembled, and the assembly position of the lens 4 is ensured, making the assembly of the lens 4 more convenient and easy to operate; in addition, since there is no need to fix the lens 4 by matching the anti-glare ring 5 with the light source assembly 2, there is no assembly tolerance between the anti-glare ring 5 and the lens 4, thus solving the problem that the lens 4 is loose after assembly or the lamp body 1, the light source assembly 2, the lens 4 and the anti-glare ring 5 cannot be assembled due to cumulative tolerance in the prior art.
