Description

Connectable refrigerator lamp

Technical Field

The invention relates to the technical field of lamps, in particular to a connectable cold cabinet lamp.

Background

In order to provide better sight and facilitate the customers to select and take articles, the manufacturers of the existing refrigerators and freezers (especially the refrigerators in supermarkets) install corresponding lighting sources inside the products. However, most of the illumination light sources on the market for refrigerators and freezers use common light sources (such as incandescent lamps or fluorescent lamps) for illumination, and the illumination light sources have the problems of high illumination energy consumption, insufficient illumination, shadow during illumination and the like. Aiming at the situation, a plurality of manufacturers improve the illumination mode of the existing refrigerator and freezer, for example, a mode of arranging a plurality of common light sources into a plurality of rows and a plurality of columns is adopted for illumination, but the illumination mode can not fundamentally solve the problems of insufficient illumination, illumination shadow and the like, and the illumination energy consumption can be further improved.

Among the prior art, the existing chinese utility model patent "single two-way refrigerator-freezer illumination LED lamp" as patent No. ZL200820207126.6 provides such refrigerator-freezer light, this refrigerator-freezer light includes the illumination LED lamp of LED light source, lamp shade and lighting fixture, wherein the lamp shade includes that light transmission unit and light diverge the unit, this light projection unit has surface and internal surface, and this surface and this internal surface all are smooth cambered surface, and equally, light diverges the unit and has surface and internal surface, this surface is smooth cambered surface, and be provided with a plurality of light reflection grooves on the internal surface. The LED refrigerator lamp adopts the LED as a light source for illumination, and has the characteristics of energy conservation, high efficiency and long service life, but the LED refrigerator lamp of the patent is troublesome to install, the lamp holder is directly fixed on the refrigerator installation surface, the lamp holder cannot be detached and installed immediately, and the installation plane can ensure the fixation of the whole lamp only by being completely matched with the contact surface of the lamp holder, so that the lamp of the patent is limited to a certain extent when in use; in addition, the refrigerator lamp of the patent is not provided with any waterproof sealing structure, the refrigerator lamp is used on a refrigerator, the environment of the refrigerator is different from the using environment of a common lamp, fog and water vapor can be generated due to temperature difference, the lamp without the waterproof sealing structure is easy to damage after being used in the refrigerator for a long time, and the service life of the lamp is greatly shortened.

Therefore, chinese patent document CN204739839U discloses an LED refrigerator lamp, including strip-shaped light-transmitting lamp holder, lamp plate, end cover, the vestibule has been seted up at the cross section middle part of lamp holder, and this vestibule is followed the length direction of lamp holder runs through the setting, lamp plate is arranged in lamp holder hole intracavity, has evenly laid a plurality of LED chips on the lamp plate, and the lamp plate terminal surface has power connection plug, and the end cover suits with the terminal surface shape of lamp holder, and one of them end cover is equipped with tiny line hole power supply connection plug and passes and be connected with the outside power of lamp body. The LED refrigerator lamp is energy-saving and environment-friendly; the lamp holder is compact and reasonable in structure, the lamp holder is integrally formed, and the sealing plug and the end cover are assembled and matched, so that the lamp holder is good in water resistance and sealing performance, a lamp is protected, and the service life is prolonged; the mounting plate and the abdicating groove can be fixed on the edge rib plate of the shelf of the bracket refrigerator, so that the mounting and dismounting are convenient, and good lighting effect is achieved for the articles on the bracket. However, the LED lamp of the above patent does not consider the light source to be fully utilized, so that the corner of the refrigerator and the lower side of the bracket are still at a position where the light source is difficult to reach when the LED is turned on, and the problem of insufficient lighting still remains.

Chinese patent document CN203927590 discloses an LED refrigerator lamp, which comprises a lamp body, a face mask, and an end cover assembly, wherein the lamp body comprises a heat sink, a triangular mounting seat is arranged on the surface of the heat sink, a limiting block is arranged on the top of the mounting seat, upper limiting grooves are respectively arranged on both sides of the limiting block, baffles are respectively arranged on both sides of the heat sink in an outward extending manner, a lower limiting groove is arranged at the joint of the heat sink and the baffles, a first mounting groove is defined by the upper limiting groove, the lower limiting groove and the side surface of the mounting seat on the same side, and an LED substrate is mounted in the first mounting; the upper end of the baffle is an inclined plane, and the inclined plane and the LED substrate are opposite to form a light reflecting surface of the LED chip. The lamp body can be provided with the two LED substrates, and the two LED substrates have different irradiation angles, so that the irradiation range of the same refrigerator lamp is enlarged, the light reflecting surface on the baffle plate can reflect the light emitted by the LED chips on the LED substrates, and the utilization rate of the light is improved. However, although the LED of the above patent solves the problems of insufficient lighting, lighting shadow and the like through different irradiation angles of the two LED substrates, the LED is generally waterproof and complicated to mount and dismount due to the complicated structure, and is easily damaged after long-term use in a refrigerator, and the service life of the lamp is greatly shortened.

In addition, with the development of technology, the refrigerator is also being developed in a large scale direction, for example, an open refrigerator, a vertical refrigerator, a multi-layer refrigerator, and the like, a single LED refrigerator lamp is difficult to satisfy the illumination in the refrigerator, and a plurality of refrigerator lamps are often required to satisfy the illumination requirement, so the connection between the refrigerator lamps also becomes a difficult point.
