Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a track lamp. Background Art

[0002] Track spotlights are one of the important lighting fixtures, widely used in commercial lighting, home lighting and engineering lighting, and play a key lighting role in shopping malls, shops, restaurants, clubs, villas, windows and other places. Track lights mainly include a lamp housing, a light source component installed in the lamp housing, a driving power supply and a back cover installed at the back port of the lamp housing. In the design of track lights on the market, the back cover is usually fixed to the back port of the lamp housing by exposed screws.

[0003] Exposed screws seriously affect the aesthetics of lamps. Modern homes and commercial spaces pursue a simple and seamless visual effect, but protruding screw heads destroy this sense of design, making the lamp look less refined and high-end overall. Especially in high-end environments that emphasize design and details, exposed screws appear particularly abrupt and inconsistent with surrounding decorative elements, reducing the overall beauty of the product.

[0004] Secondly, the exposed screw parts are easily touched accidentally or unintentionally. During long-term use, the exposed screws are more likely to loosen, which not only affects the structural stability of the lamp, but may also cause more serious problems such as the lamp falling off.

[0005] User experience is also a major disadvantage of the exposed screw design. First, cleaning and maintenance become difficult. Because the screw heads are protruding, the surface of the lamp is not smooth, which easily accumulates dust and dirt, making cleaning more difficult; especially in commercial and industrial environments, dust and dirt accumulation will be quick and obvious.

[0006] Finally, from the perspective of brand image and market competitiveness, the exposed screw design conveys an impression of lack of sophistication and professionalism. Today's consumers and commercial customers pay more and more attention to product design and quality details. Exposed screws will make people feel that the manufacturer is not careful enough in design and manufacturing, which reduces the brand's reputation and trust in consumers.

[0007] In summary, although the exposed screw connection method of the back cover of the track lamp on the market is low-cost and easy to install, it brings many disadvantages such as poor aesthetics, safety hazards, poor user experience and damaged brand image, making this design method not ideal in the lighting market that pursues high quality, high appearance and high safety. In order to effectively improve the competitiveness of products, it is particularly necessary to use hidden screw connection. Utility Model Content
