Noctilucent compasses

Abstract

The invention provides noctilucent compasses and relates to various drawing stationary such as various divider calipers, compasses or plotters. The noctilucent compasses 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 compasses are characterized in that light emitting bodies are disposed on the various drawing stationary, a light emitting body is disposed inside or on the outer side of each divider caliper, compass or plotter, a battery, a battery holder or a solar panel is disposed inside or on the outer side of each divider caliper, compass or plotter, 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, the light emitting body is controlled by the switch to be electrified and emit light, and the light is provided for writing or drawing. Due to the fact that a concave lens or convex lens is disposed at the front end of each light emitting body or the concave lens and the convex lens are disposed at the front end of the light emitting body in a matched manner, irradiation area can be expanded, and light becomes soft. The noctilucent compasses 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.
