LAMP STRUCTURE HAVING MOON PHASE CHANGE EFFECT

摘要

A lamp structure having a moon phase change effect comprises a lamp holder (110) for mounting various assemblies, a control circuit (130), a drive device (140), a gear assembly, a rotary shaft set, a light source (150), and a light blocking plate set. The control circuit (130), the drive device (140), the gear assembly, and the light source (150) are mounted in appropriate positions of the lamp holder (110). The control circuit (130) controls the drive device (140) to rotate by an angle according to a set manner. The drive device (140) is connected to the gear assembly, and drives a gear (161, 162, 163) in the gear assembly. The gear assembly is connected to the rotary shaft set. A light blocking plate (191, 192) is mounted on a rotary shaft (181, 182) respectively. The light blocking plate (191, 192) rotates with the rotary shaft (181, 182) in a synchronized manner. When rotating according to the set manner, the drive device (140) drives the gear assembly and the light blocking plate (191, 192). The light blocking plate (191, 192) blocks light from the light source. A blocking effect changes the illumination range of the lamp, so the emitted light produces a set shape, and a moon phase change effect is achieved. Another lamp structure having a moon phase change effect comprises a lamp having a moon phase change effect and a dial set (200) combined with the lamp having a moon phase change effect. When the lamp having a moon phase change effect is placed in regions of different latitude and longitude, the dial set (200) is rotated to make the moon phase presented by the lamp comply with the moon phase deflection angle viewed in the regions of different latitude and longitude.
