Description

Linear light source capable of being connected in series

Technical Field

The invention belongs to the technical field of micro-size linear light sources, and particularly relates to a tandem type linear light source.

Background

The kitchen can create a relaxed space atmosphere through lamplight, and the mood of a pleasant person is relieved. Therefore, the light must have two different functions, namely, the light is needed to improve the attention of people during meal preparation and cooking, and bright regional and decorative environment light is adopted to increase the meal atmosphere during meal entertainment. The kitchen cabinet lamps on the market at present are numerous in variety and mainly used for local illumination and decoration of kitchen cabinets, and comprise an illumination lamp in the kitchen cabinet, an operation table surface illumination lamp, a water tank illumination lamp, a hanging cabinet bottom lamp, a laminate lamp, a drawer illumination lamp, a floor cabinet illumination lamp and the like. Some of the kitchen cabinet lamps have single functions, are relatively independent, cannot be connected in series, are not strong in applicability, are not soft enough in lighting, can stimulate eyes of people, cannot achieve good structural function exertion, influence visual effects of people, and are greatly discounted in use experience of users, so that the kitchen cabinet lamps cannot be widely applied.

The traditional point light emitting is changed into a surface light emitting mode, the lighting is more uniform, the lamplight is soft and comfortable, the length of the linear light source can be freely adjusted by connecting a plurality of linear light emitting bodies in series, and the linear light source can meet diversified lamp requirements in cabinets (including kitchen cabinets, wardrobe in furniture, bookcases, sideboards and the like, and other forms such as open cabinets, showcases and the like) and other lighting environments. However, the existing linear light source is large in size and is not suitable for being installed in a cabinet. In addition, in the existing linear light source, dark areas exist at the joint of a plurality of linear light emitters in series, and full light emission without the dark areas is difficult to realize. As shown in fig. 1, each linear illuminant generally has a plurality of serially connected beads, the distance between the beads is b, the distance between the beads and the surface cover is h, the distances between the beads at the respective ends of two adjacent linear illuminants are a, b and h, which should meet certain requirements, otherwise, the surface cover cannot form a uniform surface light source, and only the beads can be seen to emit light in the form of point light sources; meanwhile, a should not be greater than b, otherwise dark areas would occur at the junction of two adjacent linear illuminants. Therefore, if the linear light source is smaller in size, h is smaller, and the form of spot light emission is more likely to occur; meanwhile, the smaller the linear light source size is, the higher the requirements on the connecting structure of two linear light sources are, in order to ensure that a is not larger than b, the finer the connecting structure of the existing linear light source cannot be, in particular the connecting structure made of materials such as aluminum alloy and the like, the smaller the linear light source size is, the larger a is not larger than b, and therefore the micro-size, dark area-free and full-light requirements of the linear light source are difficult to realize.
