Description

Technical Field

[0001] This utility model relates to the field of oven lighting system technology, and in particular to a split LED lighting component and an oven. Background Technology

[0002] In existing technology, to facilitate observation of the oven's interior, a transparent panel is typically installed on the oven and fixed to it. For even clearer observation, an internal light, usually a halogen lamp, is also installed. However, halogen lamps have several problems in practical use, such as their generally large size, which takes up extra space inside the oven, and the significant heat they generate during operation. Prolonged operation in the high-temperature environment of an oven can lead to severe light decay or damage. Therefore, an alternative lighting solution is needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a split-type LED lighting component, which solves the problems of occupying extra oven space and high heat generation leading to poor durability in existing technologies.

[0004] According to an embodiment, a split-type LED lighting assembly is provided, comprising a light-emitting part and an illumination part, and a light guide column connecting the light-emitting part and the illumination part. A light-shielding tube is provided around the light guide column. The light-emitting part includes a base, a circuit board and a heat sink mounted on the base, and a connecting tube on the base for one end of the light guide column to connect to. LED beads are mounted on the circuit board; after the LED beads emit light, the light enters the light guide column through the connecting tube. The illumination part includes a lamp housing and a lamp shade connected to the lamp housing. The end of the light guide column facing away from the connecting tube passes through the lamp housing and extends into the lamp shade. The two ends of the light-shielding tube are respectively connected to the connecting tube and the lamp housing. After the LED beads emit light, the light travels through the light guide column to the other end to achieve illumination. Only one end of the light guide column needs to be placed in an oven, resulting in a small footprint and correspondingly lower heat generation. Therefore, it solves the problems of additional oven space occupation and high heat generation leading to poor durability in existing technologies.

[0005] Furthermore, the connecting pipe is provided with a pair of bayonets on both sides, and one end of the light guide post is provided with a slot on both sides. The two slots and the two bayonets are connected by a snap ring.

[0006] Furthermore, one end of the shading tube extends into the connecting tube.

[0007] Furthermore, the lamp housing is provided with perforations, the light guide column passes through the elastic ring and then through the perforations, and the light shielding tube abuts against the elastic ring.

[0008] Furthermore, the lampshade and lamp housing are connected by threads.

[0009] Furthermore, the lampshade includes a glass cover and a connecting cylinder fixed to the glass cover, the connecting cylinder being threadedly connected to the lamp housing.

[0010] Furthermore, a first elastic washer, a stainless steel washer, and a second elastic washer are also fitted outside the connecting cylinder, located between the lamp housing and the glass cover.

[0011] Furthermore, a limit block and an elastic sheet are also connected to the lamp housing.

[0012] According to an embodiment, an oven is also provided, which includes a fixedly disposed transparent panel and the aforementioned split LED lighting assembly. The transparent panel is provided with mounting holes, the lamp housing passes through the mounting holes, and elastic sheets and limiting blocks are arranged on both sides of the transparent panel.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This solution only requires placing one end of the light guide column inside the oven to achieve illumination, which takes up little space and generates less heat. Therefore, it solves the problems of existing technologies that require additional oven space and have high heat generation leading to poor durability. Attached Figure Description

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , 2As shown, this embodiment provides an oven that uses LED lighting. Similar to existing technologies, a transparent panel 2 is fixedly installed on the oven 1 for easy observation. However, unlike existing technologies, this solution also includes a split-type LED lighting assembly. The transparent panel 2 has mounting holes. The lighting assembly includes a lighting section, which includes a lamp housing 3 connected to the mounting holes. The lamp housing 3 is connected to a lampshade, which is located inside the oven 1. Specifically, the lampshade includes a connecting cylinder 5 and a glass cover 4 connected to the connecting cylinder 5 (the glass cover 4 may include a connecting sleeve wrapped around a glass plate). The connecting sleeve and connecting cylinder 5 can be an integral structure. The connecting cylinder 5 and the lamp housing 3 can be threaded together. The lighting assembly also includes a light-emitting part, which includes a base 6 mounted on the oven 1 (external). A circuit board 7 and a heat sink 8 are mounted on the base 6. LED beads are mounted on the circuit board 7. A connecting pipe 9 is also fixedly connected to the base 6, and a light guide column 10 is inserted into the connecting pipe 9. The other end of the light guide column 10 passes through the lamp housing 3 (which has a perforation) and extends into the lamp shade. In this way, after the LED beads emit light, the light enters the light guide column 10 through the connecting pipe 9, and the light travels along the light guide column. Light can reach the lampshade and achieve illumination; furthermore, a light-shielding tube 11 is also wrapped around the light guide column 10 to prevent light leakage. The two ends of the light-shielding tube 11 abut against the base 6 and the lamp housing 3, respectively. In this solution, the light is emitted from the other end of the light guide column 10 to achieve illumination. Only one end of the light guide column 10 needs to be placed in the oven 1. This solution adopts a separate structure for light emission and illumination by setting the lamp beads, circuit board 7 and lampshade to be located outside and inside the oven 1, respectively. This results in a small space occupation and correspondingly lower heat generation, solving the problem of additional space occupation in the oven 1 in the prior art. In addition to addressing the issue of high heat generation leading to poor durability, a further solution involves connecting a limiting block 12 and an elastic sheet 13 to the lamp housing 3. The limiting block 12 and the elastic sheet 13 are located on opposite sides of the mounting hole. One end of the elastic sheet 13 is integrally formed with the lamp housing 3, while the other end is a free end. The entire lamp housing 3 can be made of metal. When assembling the lamp housing 3, the free end of the elastic sheet 13 can be pressed first to allow the lamp housing 3 to pass smoothly through the mounting hole. Then, the pressed elastic sheet 13 is released, and the elastic sheet 13 returns outward and cooperates with the limiting block 12 to allow the lamp housing 3 to be installed on the transparent panel 2.

[0017] like Figure 1 , 2As shown, in this scheme, the connecting tube 9 is also provided with a pair of bayonet slots 14 on both sides, and the light guide column 10 is provided with corresponding slots 15 on both sides. The two slots 15 and the two bayonet slots 14 are connected by a snap ring 16, so that the light guide column 10 and the connecting tube 9 can be detachably connected. At the same time, one end of the light shielding tube 11 extends into the connecting tube 9. Specifically, the light shielding tube 11 can be made of glass fiber tube. An elastic ring 17 can be fitted on the light guide column 10. The end of the light shielding tube 11 away from the connecting tube 9 can abut against the elastic ring 17 so that the elastic ring 17 is elastically pressed between the light shielding tube 11 and the lamp housing 3. In this way, the light shielding tube 11 forms a full-coverage light shield on the outside.

[0018] like Figure 1 , 2 As shown, in a further embodiment, a first elastic washer 18, a stainless steel washer 19, and a second elastic washer 20 are fitted outside the connecting cylinder 5 between the lamp housing 3 and the glass cover 4. After assembly, this makes the lamp housing 3 and the lamp cover more stable, and also prevents accidental vibrations from affecting the glass cover 4 and the end of the internal light guide column 10. In this embodiment, the first elastic washer 18, the second elastic washer 20, and the elastic ring 17 are all made of high-temperature resistant silicone material.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
