Description

Line lamp capable of emitting light from two sides

Technical Field

The utility model relates to the field of lamps, in particular to a line lamp capable of emitting light from two sides.

Background

The line lamp is a novel decorative lamp and is increasingly popular in places such as home, market, coffee shops and the like in recent years. The line lamp not only can play a role in illumination, but also can serve as a unique decorative element, and different atmospheres are created through different colors, brightness and darkness and other modes, so that the attractiveness and artistic sense of the space are improved.

Along with the continuous improvement of life quality requirements of people, the requirements of decorative lamps are also higher and higher. Firstly, the existing line lamp can only emit light from one side, so that the light irradiation of the lamp is single, and the attractiveness of the whole space is affected. And meanwhile, the requirements of thousands of changes of modern decoration requirements cannot be met. Secondly, the light of the existing line lamp is directly emitted from the light emitting surface, and the design can lead a user to feel very glaring, especially in the evening or in a darker environment. Such glare may affect the visual experience of the user and may even cause discomfort. To avoid this, most of the line lamps can be installed hidden in the grooves, so that the installation environment and the location of the line lamps are limited, although the dazzling light can be avoided. For example, in applications where a ceiling or wall mounting is desired, a line light may not be satisfactory. In addition, the line lamp hidden in the groove is also difficult to replace or repair, which brings inconvenience to the user.

In addition, in the use process of the line lamp, the problem of poor disassembly and assembly of the end cover becomes an important factor for restricting the use of the line lamp. At present, the existing line lamp end cover is fixed by screwing, so that the disassembly and assembly are inconvenient in high-altitude operation, and operators are tired in high-altitude lifting double-hand operation during disassembly and maintenance or installation, and the operation is inconvenient. The other is that the end cover is directly fixed by the interference fit after the insertion part is arranged on one side of the end cover and inserted into the lamp housing, but the end cover is easy to loose because of the cable pulling of external connection during the installation. And when the end cover which is pulled out and plugged in the way is installed at a lower position, children can easily pull out the end cover, and potential safety hazards appear.

Thus, further optimization and improvement are needed for existing line lamps.
