Description

Technical Field

[0001] The invention relates to the technical field of lamps, and in particular to a lamp that can be connected to a refrigerator. Background Art

[0002] In order to provide a better sight and facilitate customers to select and take items, current refrigerator and freezer manufacturers (especially supermarket freezers) will install corresponding lighting sources inside the products. However, most of the lighting sources used in refrigerators and freezers on the market are ordinary light sources (such as incandescent lamps or fluorescent lamps). This type of lighting source has many problems such as high lighting energy consumption, insufficient lighting, and shadows during lighting. In response to this situation, many manufacturers have made improvements to the existing lighting methods of refrigerators and freezers, such as arranging several ordinary light sources into multiple rows and columns for lighting. However, this lighting method cannot fundamentally solve the problems of insufficient lighting and lighting shadows, and will further increase lighting energy consumption.

[0003] In the prior art, the existing Chinese utility model patent "Single and double direction freezer lighting LED lamp" with patent number ZL200820207126.6 provides such a freezer lighting lamp, which includes an LED light source, a lampshade and a lamp stand. The lampshade includes a light transmitting unit and a light diverging unit. The light projecting unit has an outer surface and an inner surface, and both the outer surface and the inner surface are smooth curved surfaces. Similarly, the light diverging unit has an outer surface and an inner surface. The outer surface is a smooth curved surface, and a plurality of light reflecting grooves are arranged on the inner surface. The above patent uses LED as the light source for lighting, which has the characteristics of energy saving, high efficiency and long service life. However, the LED freezer lamp of the above patent is more troublesome to install. The lamp holder is directly fixed to the installation surface of the freezer, and cannot be disassembled and installed immediately. Moreover, the installation plane must be fully matched with the contact surface of the lamp holder to ensure the fixation of the entire lamp, which makes the lamp of the patent subject to certain restrictions when used; in addition, the freezer lamp of the above patent is not provided with any waterproof sealing structure. Since the freezer lamp is used in a freezer, and the environment of the freezer is different from that of ordinary lamps, fog and water vapor will be generated due to the temperature difference. The lamp without a waterproof sealing structure is easily damaged during long-term use in the freezer, which greatly shortens the service life of the lamp.

[0004] Therefore, Chinese patent document CN204739839U discloses an LED refrigerator lamp, including a strip-shaped light-transmitting lamp holder, a lamp board, and an end cover. A hole cavity is opened in the middle of the cross section of the lamp holder, and the hole cavity is arranged along the length direction of the lamp holder. The lamp board is placed in the hole cavity of the lamp holder, and a number of LED chips are evenly arranged on the lamp board. The end face of the lamp board has a power connection plug, and the end cover is adapted to the shape of the end face of the lamp holder, and one of the end covers is provided with a small wire hole for the power connection plug to pass through and connect to the power supply outside the lamp body. The LED refrigerator lamp of the present invention is energy-saving and environmentally friendly; its structure is compact and reasonable, and the integrated molding of the lamp holder, the sealing plug, and the assembly of the end cover make it waterproof and well sealed, which protects the lamp and prolongs its service life; the setting of its mounting plate and the clearance groove can fix it on the edge rib plate of the bracket refrigerator shelf, which is not only convenient for installation and disassembly, but also has a good lighting effect on the items on the bracket. However, the LED lamp of the above patent does not take into account the full use of the light source, so that when the LED is turned on, the corners of the refrigerator and the bottom of the bracket are still in a position where the light source is difficult to reach, and the problem of insufficient lighting still exists.

[0005] Chinese patent document CN203927590 discloses an LED refrigerator lamp, including a lamp body, a mask, and an end cover assembly. The lamp body includes a radiator, a triangular mounting seat is provided on the surface of the radiator, a limit block is provided on the top of the mounting seat, and upper limit grooves are provided on both sides of the limit block. Baffles are respectively extended outward on both sides of the radiator, and a lower limit groove is provided at the connection between the radiator and the baffle. The upper limit groove, the lower limit groove and the side of the mounting seat on the same side together form a first mounting groove, and the LED substrate is installed in the first mounting groove; the upper end of the baffle is an inclined surface, and the inclined surface and the LED substrate form a reflective surface of the LED chip relative to the LED substrate. Two LED substrates can be installed on the lamp body of the present invention, and the illumination angles of the two LED substrates are different, thereby increasing the illumination range of the same refrigerator lamp, and the reflective surface on the baffle can reflect the light emitted by the LED chip on the LED substrate, thereby improving the utilization rate of light. However, although the LED in the above patent solves the problems of insufficient lighting and lighting shadows by using two LED substrates with different illumination angles, its complex structure makes it generally waterproof and complicated to install and disassemble. It is easy to be damaged when used in a freezer for a long time, which greatly shortens the service life of the lamp.

[0006] In addition, with the development of technology, freezers are also moving towards large-scale development, such as open freezers, vertical freezers and multi-layer freezers, etc. A single LED freezer light can hardly meet the lighting requirements inside the freezer, and often multiple freezer lights are required to meet the lighting requirements. Therefore, the connection between freezer lights has also become a difficulty. Summary of the invention

[0007] In order to solve the above technical problems, an object of the present invention is to provide a connectable refrigerator lamp which has good waterproof performance, is easy to install and fully utilizes the light source.
