Description

technical field [0001] The present invention relates to an LED lighting lamp capable of immediately providing lighting to the inside of a storage room when box-type household appliances such as freezers, refrigerators, and disinfection cabinets are turned on, and particularly relates to a box-type household appliance suitable for being provided with a top-opening cover LED lights. Background technique [0002] In the prior art, as one of the box-type household appliances, the horizontal freezer, that is, the top-opening type freezer, mostly does not have a lighting lamp that can provide instant lighting for the storage room when the top cover of the freezer is opened. It is very inconvenient to pick and place items when you need to use external light sources. There are also individual horizontal freezers equipped with lighting devices, which include a power supply line that can be connected to 220V mains, a weight switch on the power supply line, and an incandescent bulb co...
