Description

Lighting device and vacuum cleaner comprising the same The present disclosure relates to a lighting device and a cleaning device including the same. Thanks to advancements in electronic technology, most households use various types of vacuum cleaners, such as robot vacuums and cordless vacuums. When using cordless or corded vacuums, users can clean with the vacuum head attached to the floor. In this case, cleaning can be much easier if various foreign substances, such as dust or hair fallen on the floor surface, are visible to the naked eye. However, if the cleaning space is dark or the lights are off, it is difficult for the user to directly identify foreign substances on the floor surface with the naked eye. To resolve these problems, a lighting device may be installed in the vacuum cleaner. However, depending on the placement location or direction of the lighting device, there may be significant differences in the effectiveness of identifying foreign substances. Therefore, there has been a need for technology that enables the easy identification of foreign substances when using lighting devices.
