No-main-light design has become the mainstream choice for home decoration lighting, but the thickness of traditional no-main-light trunking is mostly 5-8cm, which is easy to compress the floor height after installation, bringing a sense of oppression to small apartments. Today, with the breakthrough of production technology, ultra-thin no-main-light trunking has emerged as the times require, with the thickness successfully compressed to less than 3cm, and even 1.5cm ultra-thin models have been launched, completely solving the space pain point of installing no-main-light in small apartments.​

The design breakthrough of ultra-thin no-main-light trunking comes from the dual optimization of materials and structure. In the production link, high-strength aviation-grade aluminum alloy is used as the base material. On the premise of ensuring structural stability, the wall thickness of the trunking is reduced to 0.8-1.2mm, which is 60% lighter than the traditional trunking, and the heat dissipation performance is improved. In terms of structural design, the combination of "embedded card slot + hidden light strip" is adopted. The light strip fits perfectly with the trunking, and the light forms diffused reflection through the curved light guide plate, avoiding direct glare, and the light coverage is wider. A 1-meter-long trunking can achieve uniform lighting of 2-3 meters.​

The significantly improved installation adaptability has become the core competitiveness of ultra-thin trunking. The product supports various installation methods such as ceiling embedded, wall embedded and skirting board type. Small apartments can choose ceiling shallow slot installation, which hardly occupies floor height; for old houses where the ceiling cannot be modified, wall pasting installation can be adopted, which is integrated with the wall through ultra-thin design without damaging the original decoration. At the same time, the length of the trunking can be customized on demand, with the shortest 30cm and the longest 3 meters, supporting seamless splicing to adapt to different space sizes.​

In terms of functional design, the ultra-thin no-main-light trunking balances practicality and intelligence. It supports three-color adjustment of warm light, cool light and neutral light, and the brightness can be controlled by remote control or mobile APP to meet different needs such as daily lighting and atmosphere creation; some products integrate human body induction function, the light turns on when people come and off when people leave, saving energy and environmental protection. Application scenarios have expanded from residential living rooms and bedrooms to small apartment spaces such as apartments, lofts and commercial studios. While improving the lighting effect, it makes the space appear more spacious and transparent through the sense of visual extension.​

In the future, the ultra-thin no-main-light trunking will further develop towards integration and intelligence, and may integrate functions such as wireless charging and Bluetooth speakers. At the same time, the production process will be optimized to reduce costs, so that more small apartment users can enjoy the comfortable experience of no-main-light design, and promote the transformation of home decoration lighting towards "space-friendly".
