Automatic control LED illumination lamp and horizontal device using same

Abstract

The invention discloses an automatic control LED illumination lamp and a horizontal device using the same. The LED illumination lamp comprises a power supply line capable of being connected into a 220V mains supply, a voltage-reducing driving circuit, a rectifying circuit, a filtering circuit and an LED light source, wherein the voltage-reducing driving circuit is connected into the power supply line, the rectifying circuit is connected with the voltage-reducing driving circuit, the filtering circuit is connected with the rectifying circuit, and the LED light source is connected to an output end of the filtering circuit; and a gravity switch is arranged on a line between the voltage-reducing driving circuit and the rectifying circuit. The illumination lamp provided by the invention has the characteristics of low energy consumption, long service life, easy installation, and the like and is convenient to popularize and apply. When a top cover of the horizontal device rotates upwards andis opened at a set angle, the circuit automatically conducts the LED to illuminate under the control of the gravity switch so as to illuminate the interior of an object storage room below the LED. When the top cover is closed, the circuit is automatically switched off, the LED is extinguished, thus the horizontal device is more convenient for users to use.

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 lighting lamps; also relates to a horizontal device using automatically controlled LEDs. 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-opening 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 c...

AI Technical Summary

Problems solved by technology

The power of the light bulb driven by the above weight switch is about 15W. The weight switch is bulky and heavy, and it is inconvenient to install it on the inside of the top-opening cover.
