Patent attributes
The invention is a modification of a standard level used for construction work to determine if a surface is horizontal, of to draw a reference line to indicate horizontal. The invention is an elongated 2×4 housing that is 24″ long. In the center of the housing is a cut-out for a digital display of a length of LED lights, in the preferred embodiment nine lights. There are two cut-outs on either side of the center to provide hand-holds. Between these hand-hold cut-outs are circular displays with an LED strip with three lights. There is an on/off switch on one side and a control switch on the other side. When the control switch is turned on it activates an internal level circuit board is activated. When the level is placed on a surface it will display green when level. If it is not level it will display red, with a white light showing which way to move the level, similar to a standard level bubble. For example, if the white light is to the right it means that side is higher, and the left side must be lifted to find level. The invention can also be used to show vertical (or 90 degrees from horizontal). When the control switch is pressed it will switch the control board to vertical mode, and the two small circular displays will indicate which way to move to find vertical.
