Road sign projection device and road sign projection street light

Abstract

The invention discloses a guidepost projection device and a guidepost projection road lamp. The guidepost projection device comprises a guidepost LED array and a plurality of condensing lenses, the guidepost LED array consists of a plurality of LED lamps in arrangement, and an arrangement shape is identical to a shape of a guidepost to be projected. Moreover, an arrangement shape of the condensing lenses matches with the shape of the guidepost LED array to enable light rays emitted by the guidepost LED array to form a guidepost shape after passing the condensing lenses, and the light rays in the guidepost shape form a guidepost after being projected on a pavement. The guidepost projection road lamp comprises a lighting device, the guidepost projection device and a lamp bin. By the aid of the condensing lenses, intensity of the light rays emitted by the guidepost projection device can be improved, and the projected guidepost is clear; a night effect of the guidepost is enhanced, and an astonishing visual effect is generated when a road is overlooked; artificially drawn guideposts of newly constructed roads can be omitted, the guidepost projection device in the guide post projection road lamp is directly replaced when the guidepost needs to be modified, and damage to the guide post due to road repairing is avoided.

Description

technical field [0001] The invention relates to a road sign projection device and a road mark projection street lamp. Background technique [0002] In order to achieve the smooth flow of the road, relevant road marking lines are drawn on the road surface to inform drivers to abide by relevant driving regulations. Existing road markings all adopt manual drawing, and the display effect of these drawn road markings is not strong at night. At the same time, if the manual drawing is wrong, it is not easy to modify, and the modification will inevitably cause damage to the road; with the continuous development of traffic roads, it is also necessary to modify the road signs drawn on the road surface. Contents of the invention [0003] The object of the present invention is to provide a road sign projecting device and a road sign projecting street lamp which can enhance the display effect of road signs at night and replace road signs without causing damage to the road surface. ...
