Level

1. A level comprising:

a sensor that detects a tilt angle;

a display unit including a plurality of strip-shaped display members that emits light linearly by an LED and displays the tilt angle; and

a control circuit that receives a signal from the sensor and outputs a control signal so that a specific strip-shaped display member glows,

wherein the strip-shaped display members include one horizontal strip-shaped display member positioned at a middle of the display unit and a plurality of strip-shaped display members for tilt-angle display that has tips bent toward a center of the display unit, wherein each of the strip-shaped display members has an LED attached to an end, and a pair of strip-shaped display members provided to be point-symmetrical with respect to the center of the display unit simultaneously glows according to the tilt angle.

2. The level according to claim 1 , wherein the level is configured to emit different sounds corresponding to light emissions of the strip-shaped display members.

3. The level according to claim 1 , wherein LEDs of different colors are attached to ends of the respective strip-shaped display members.

4. The level according to claim 1 , wherein the level is configured to emit different sounds corresponding to light emissions of the strip-shaped display members.

5. The level according to claim 1 , wherein LEDs of different colors are attached to ends of the respective strip-shaped display members.

6. The level according to claim 5 , wherein the level is configured to emit different sounds corresponding to light emissions of the strip-shaped display members.
