It's a logo to represent a lamp. The logo resembles a table lamp with a trapezoid shape lamp shade and a circular base. The middle of the map is circular at the top and flows inward down into the base.
This is a Lamp Filled icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
