Noctilucent rulers

Abstract

The invention provides noctilucent rulers and relates to various drawing stationary such as triangular rulers, straight rulers, protractors or angle gauges. The noctilucent rulers are suitable for being used in environments such as a dark environment, a weak-light environment or a night environment in which writing is affected by light insufficiency. The noctilucent rulers are characterized in that light emitting bodies are disposed on various drawing stationary, a light emitting body is disposed inside or on the outer side of the drawing stationary, a battery, a battery holder or a solar panel is disposed inside or on the outer side of each noctilucent ruler, the battery or the battery holder is connected with the light emitting body through a wire and a switch, or a circuit board or a chip is disposed on the drawing stationary, the light emitting body is controlled by the switch to be electrified and emit light, and the light is provided for writing or drawing. The noctilucent rulers have the advantages that the writing and drawing requirements in special environments can be satisfied, the eyes of users can be protected at the same time, learning fun of students is increased, and the creation consciousness of the students is motivated.
