[0002] With rising living standards and increasing demand for smart technology, lighting fixtures that combine illumination and sensor functions are gaining popularity in the market. However, effectively integrating multiple functional modules into compact lighting fixtures such as wall lamps and table lamps remains a technical challenge.

[0003] Currently, most lighting fixtures on the market employ external functional modules or simple splicing designs, resulting in increased product size, obtrusive appearance, low internal space utilization, and often problems such as poor heat dissipation and signal interference. Although there are some integration attempts in existing technologies, they usually fail to rationally arrange the spatial layout and installation structure of the sensing module and the light source module, making it difficult to achieve a stable and efficient integrated design within a limited space.

[0004] In view of this, it is indeed necessary to improve the existing lighting fixtures to solve the above problems. Utility Model Content

[0023] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] Please see Figures 1 to 6 As shown, this embodiment of the utility model provides a lamp 100. The lamp 100 can be an outdoor or indoor lamp that integrates sensing and lighting functions, such as a courtyard lamp, corridor lamp, or wall lamp.

[0025] The lamp 100 includes a main structure, namely a light-shielding rod 1. The light-shielding rod 1 is typically a long rod, and its length can be set according to actual installation requirements. The light-shielding rod 1 has a recessed cavity 11 for mounting the sensing element 2 and the light source module 3, and the cavity 11 has an opening facing the external environment. The sensing element 2 can be sound-activated or heat-sensing, etc.

[0026] On opposite sides of the receiving cavity 11 (i.e., on both sides along the length of the light-shielding rod 1), the receiving cavity 11 is provided with an inwardly recessed first recessed groove 12 and a second recessed groove 13. The cross-sectional area of ​​both the first recessed groove 12 and the second recessed groove 13 is smaller than the cross-sectional area of ​​the receiving cavity 11. Furthermore, the first recessed groove 12 and the second recessed groove 13 are spaced apart along the length of the receiving cavity 11. In this way, two functionally defined installation areas are formed.

[0027] Specifically, a first mounting region 120 for mounting the sensing element 2 is formed between the first recessed groove 12 and the opening of the receiving cavity 11. A second mounting region 130 for mounting the light source module 3 is formed between the second recessed groove 13 and the opening of the receiving cavity 11.

[0028] In the opening direction of the receiving cavity 11, the installation depth of the first mounting area 120 is greater than the installation depth of the second mounting area 13. Thus, the sensing element 2 can be installed relatively deeper inside the light-shielding rod 1, while the light source module 3 is installed relatively closer to the opening. This design reduces direct interference from light and heat from the light source on the sensing element 2.

[0029] Preferably, a substrate 14 is provided inside the receiving cavity 11. The substrate 14 is positioned directly opposite the opening of the receiving cavity 11. The substrate 14 can be independently fixed to the back wall of the receiving cavity 11, or it can be integrally formed with the light-shielding rod 1. One of the main functions of the substrate 14 is to support the sensing element 20. The first recessed groove 12 is directly formed on the substrate 14.

[0030] In this embodiment, the lamp 100 further includes a limiting member 4. The limiting member 4 is used to install into the first mounting area 120, and the installation method can be a snap-fit, threaded fixation, etc., which is not limited. The limiting member 4 is connected to the sensing element 2 and restricts and presses it into the corresponding position on the substrate 14 to ensure the installation stability of the sensing element 2.

[0031] Preferably, the limiting member 4 has a through opening 41 on the side opposite to the sensing element 2. Correspondingly, the sensing element 2 has a protruding sensing part 21, which at least partially penetrates or even passes through the opening 41. In this way, the sensing part 21 can be exposed to the external environment through the opening 41 to receive signals, while the limiting member 4 serves both a fixing function and the opening 41 forms a protective guiding channel, which helps to regulate the sensing path and prevents debris from directly contacting the sensing part 21.

[0032] The sensing element 2 is provided with a mounting portion 22, and the limiting member 4 is provided with a mounting hole 42 at a corresponding position. By inserting the mounting member 5 through the mounting portion 22 of the sensing element 2 into the mounting hole 42 of the limiting member 4 and locking it, the sensing element 2 can be firmly fixed to the limiting member 4. The mounting member 5 can be a screw.

[0033] In this embodiment, the mounting portion 22 is a semi-arc groove recessed on the body of the sensing element 2. During assembly, the semi-arc groove is aligned with the mounting hole 42. The mounting member 5 includes a pressing portion and a fixing portion. The fixing portion is mated with the mounting hole 42, and the pressing portion abuts against and presses the outer peripheral curved surface of the semi-arc groove. When the mounting member 5 is tightened, the pressing portion presses the sensing element 2 toward the main body of the limiting member 4 to achieve firm fixation. Preferably, at least part of the pressing portion is located in the first recessed groove 12 to make full use of the space and make the structure more compact.

[0034] Two extending portions 15 protruding inward are provided on the side of the receiving cavity 11 opposite to the side where the sensing element 2 is disposed. The two extending portions 15 may be bosses or ribs integrally extending from the side wall of the receiving cavity 11, and they are vertically connected to the edge of the substrate 14. A gap is maintained between the two extending portions 15, thereby forming the second recessed groove 13. The two extending portions 15 themselves serve as mounting brackets for supporting the light source module 3, and both sides of the light source module 3 can be lapped or fixed on the extending portions 15.

[0035] The light source module 3 and the sensing element 2 are electrically connected through wires to realize linkage control. A wiring cavity for the wires to pass through is formed inside the second recessed groove 13. In this way, the wiring is concealed and neat, avoiding messy lines and possible interference.

[0036] In the length direction of the light shielding rod 1, the length of the second mounting area 130 is greater than one half of the total length of the light shielding rod 1. In this way, sufficient installation space is provided for the light source module 3, supporting the use of longer and brighter light strips or modules to meet the demand for large-area illumination, while maintaining the balance and aesthetics of the structure.

[0037] A fixing area is formed between the first recessed groove 12 and the second recessed groove 13. The light shielding rod 1 is provided with a fixing member 6 mounted in the fixing area. The fixing member 6 may be an independent pressing plate, cover plate or frame structure, or a supporting rod. Its function is to limit the sensing element 2 (in this embodiment, the limitation on the sensing element 2 is completed synchronously by limiting the limiting member 4) and the light source module 3 located on both sides in the receiving cavity 11 from the front, preventing them from coming out of the opening, and possibly assisting in final sealing or appearance beautification.

[0038] In summary, the lamp 100 of this utility model provides an inwardly recessed first groove 12 and a second groove 13 on opposite sides of the receiving cavity 11 of the light-shielding rod 1. The cross-sectional areas of the first groove 12 and the second groove 13 are both smaller than the cross-sectional area of ​​the receiving cavity 11 and are spaced apart. A first mounting area 120 for mounting a sensing element 2 is formed between the first groove 12 and the opening of the receiving cavity 11, and a second mounting area 130 for mounting a light source module 3 is formed between the second groove 13 and the opening of the receiving cavity 11. In the opening direction of the receiving cavity 11, the mounting depth of the first mounting area 120 is greater than the mounting depth of the second mounting area 130. Thus, while maintaining a compact structure, it can accommodate both sensing and lighting functions, achieving high space utilization and practicality.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
