Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an LED downlight with a built-in dial switch. Background Art

[0002] LED downlights are commonly used lighting fixtures in the building decoration industry. They are widely used in homes, hotels, shopping malls, offices and other occasions. When used, they are embedded in the ceiling to maintain the overall unity of the building's decorative style.

[0003] Some existing LED downlights can adjust the color temperature or power through a dip switch. The dip switch is usually placed at the rear or side of the housing and can be hidden in the ceiling together with the housing during installation. During the production process, in order to save mold opening costs, the housing with a dip switch and the housing without a dip switch will share the same mold. For products without a dip switch, an insert will be set on the mold to block the hole corresponding to the dip switch. After molding, the mold print of the insert will be left on the housing, affecting the appearance of the lamp and the purchaser's willingness to purchase. For ease of operation, the dip switch is generally exposed to the housing. The installation gap between it and the housing will increase the possibility of internal components being corroded by the outside, reduce the protection ability of the LED downlight, and make it difficult to meet the requirements for protection level. In addition, the dip switch exposed at the rear of the housing will also increase the height of the LED downlight, which will have a certain impact on the installation work. Summary of the invention

[0025] Embodiment 1:

[0026] like Figure 1 As shown, this embodiment provides an LED downlight with a built-in DIP switch, including a housing 100, a light-emitting component 106 installed in the housing 100, and spring clips installed on both sides of the housing 100. The spring clips are omitted in the figure, and a DIP switch 500 is provided at the tail of the housing 100.

[0027] like Figure 2 As shown, the tail of the housing 100 is formed with a groove 600 that is recessed into the inside of the housing 100, and the bottom of the groove 600 is provided with a mounting hole 602. The DIP switch 500 is installed in the mounting hole 602. The opening of the groove 600 is provided with an end cover 200 that can completely cover the groove 600. The end cover 200 and the housing 100 are detachably connected through a snap-fit ​​structure, which facilitates the rapid installation and removal of the end cover 200. The front of the end cover 200 is flush with the tail end face 101 of the housing 100, which can prevent the end cover 200 from affecting the original height of the LED downlight.

[0028] like Figure 3 As shown, the back of the end cap 200 is formed with a circle of side strips 202 extending toward the bottom of the groove 600. The height of each part of the side strips 202 varies with the depth of the groove 600. The outer wall of the side strips 202 and the inner wall of the groove 600 are matched with each other, which can improve the stability of the installation of the end cap 200. In order to facilitate the accurate insertion of the side strips 202 into the groove 600 when the end cap 200 is installed, the side strips 202 are provided with guide grooves 203, and the inner wall of the groove 600 is provided with guide strips 601 corresponding to the guide grooves 203, which can guide the side strips 202 when they are inserted into the groove 600, and limit the horizontal displacement of the end cap 200.

[0029] The end cap 200 extends outward to form a protruding section 200.1 that exceeds the lateral outer wall of the housing 100. The back of the protruding section 200.1 is provided with a male buckle 201 of the buckle structure. The lateral outer wall of the housing 100 is provided with a positioning platform 104 that protrudes outward. The top surface of the positioning platform 104 is not higher than the tail end surface 101 of the housing 100 and is provided with a positioning port 102 that cooperates with the end cap 200. The positioning port 102 is provided with a notch 103 for routing the wires of the downlight on the lower side of the end cap 200. Generally speaking, the notch 103 is arranged opposite to the wiring terminal 105 of the light-emitting component 106 for easy routing. The bottom of the positioning platform 104 is provided with a female buckle 107 of the buckle structure. Since the opening of the LED downlight during installation will be larger than its cylindrical body, the protruding section 200.1 of the end cap 200 and the positioning platform 104 will not affect the installation work.

[0030] The male buckle 201 is in a strip shape and can be inserted into the female buckle 107 . A plurality of inverted teeth are formed on the male buckle 201 . The inverted teeth are hooked on the edge of the female buckle 107 to limit the up and down displacement of the end cover 200 .

[0031] As another implementation, the snap-fit ​​structure may be disposed within the groove 600 , which can be achieved by simply disposing a female snap 107 in the groove 600 and a male snap 201 on the end cover 200 .

[0032] Obviously, the above-mentioned buckle structure can also be replaced by other buckle structures or conventional methods such as screw fixing.

[0033] In this embodiment, the dip switch 500 is built into the bottom of the groove 600, which will not affect the operation of the dip switch 500 and also avoids the dip switch 500 affecting the original height of the LED downlight. When the housing 100 with the dip switch 500 and the housing 100 without the dip switch 500 share the same mold, whether the mounting hole 602 of the dip switch 500 is directly molded without an insert, or the mold print is generated by blocking the hole corresponding to the dip switch 500 with an insert in consideration of protection requirements, it will be blocked by the end cover 200 at the opening of the groove 600 and will not affect the appearance of the housing 100.

[0034] Embodiment 2:

[0035] like Figure 4As shown, on the basis of Example 1, in this embodiment, a sealing groove is provided at the bottom of the groove 600, and a circle of sealing strip 300 is installed in the sealing groove. The sealing strip 300 is positioned by the sealing groove to reduce the displacement of the sealing strip 300 during installation and use. The bottom of the side strip 202 on the back of the end cover 200 contacts the sealing strip 300 to form a sealed space, and the dip switch 500 and the connection terminal 105 of the light-emitting component 106 are both located in the sealed space 400. After the side strip 202 is fully inserted, the buckle structure can make the end cover 200 in close contact with the sealing strip 300 to ensure sealing.

[0036] In this embodiment, a sealing strip 300 is arranged to contact the side strip 202 to form a sealed space 400. The DIP switch 500 and the wiring terminal 105 are located in the sealed space 400, thereby reducing the impact of external corrosion on the wires, the wiring terminal 105 and the internal components of the downlight, and effectively improving the protection capability of the LED downlight.

Since the opening of the LED downlight during installation will be larger than its cylindrical body, the top surface of the end cover 200 can be flush with the lateral outer wall of the housing 100, or higher than the lateral outer wall, which does not affect the installation work.

[0040] The bottom of the groove 600 is provided with a sealing groove, in which a circle of sealing strip 300 is installed, and the back of the end cover 200 contacts the sealing strip 300 to form a sealed space 400, and the code switch 500 and the connection terminal 105 of the light-emitting component 106 are arranged together in the sealed space 400, so as to reduce the influence of external corrosion on the wire, the connection terminal 105 and the internal components of the downlight, and improve the protection capability of the LED downlight. The buckle structure can be arranged within the range of the sealed space 400, or it can be arranged outside the range of the sealed space 400.

[0041] The back of the end cover 200 is provided with a side strip 202 extending toward the bottom of the groove 600, the bottom of the side strip 202 is in close contact with the sealing strip 300, and the outer wall of the side strip 202 is in gap fit with the inner wall of the groove 600. The side strip 202 is provided with a guide groove 203, and the inner wall of the groove 600 is provided with a guide strip 601 corresponding to the guide groove 203.
