The utility model discloses a pattern projecting apparatus for automatically identifying and playing an audio. The projecting apparatus includes a first housing, a light-emitting assembly, a film assembly, an audio assembly, and an imaging assembly. The audio assembly includes a control board, an electronic label corresponding to a film sheet, an identifying module for identifying the electronic label and arranged on the control board, a storage medium pre-stored with an audio corresponding to a galactic starry sky pattern, and a speaker electrically connected to the control board. The electronic label is arranged on the film assembly. When the film assembly is mounted in a first mounting hole, the identifying module identifies the electronic label on the film sheet, positions the audio corresponding to the electronic label in the storage medium and plays the audio via the speaker, so that the galactic starry sky pattern projected by the projecting apparatus is played in combination with the audio. A user can hear an audio corresponding to a pattern of the film sheet when changing different film sheets. Therefore, the user's experience is effectively improved, and the practicability of the projecting apparatus is enhanced.

A communications apparatus to be installed on high mast lighting systems or other vertical assets with significant above ground projections. The apparatus is designed to mount to existing light ring spokes or other existing mounting structures. The system is powered during nighttime hours by grid power and during daylight hours by internal battery storage. A uniquely-oriented directional dual polarity MIMO antenna adapted for high mast mounting supports communications with mobile vehicles using MIMO emissions in a North/South and East/West polarization. Mobile vehicle clients may then use dual polarized antennas including skyward-looking radiation patterns with major lobes that are oriented directly up towards the sky.

An LED lighting array system includes discrete lighting modules spatially arrayed along a support member to provide illumination of items within a display case.
