Product Features
● Application
The "LANG CHAO" series public service smart bollard lamp is an integrated smart lighting fixture that combines digital IP audio, one-touch assistance, public WIFI signal transmission, and other features. It is appropriate for smart city applications in upscale outdoor spaces including parks, commercial streets, business districts, and smart communities.
● Lamp Features
/A public WIFI antenna on top of the lamp provides WIFI service, enabling users' mobile devices to connect to the internet (see page 24: WIFI signal transmission).
/An "SOS" one-touch help intercom module is included with the lamp. In an emergency, users can use the button to instantly send a distress signal, which will alert the pre-set alert center for prompt assistance (see page 24: one-touch help service).
/HD intercom: Clear audio transmission in challenging outdoor settings is ensured by the one-touch help intercom module's compatibility for HD voice communication. The alert center is always accessible to users.
/Two-way calling: terminal and server calls are possible with the one-touch help intercom module.
/An internal light-transmitting design is used in the lighting area. For optimal anti-glare performance, downward-tilted wave pattern hollow parts regulate light onto the ground, giving useful illumination while avoiding direct eye glare.
/The smart central control system is connected to an integrated intelligent control module that enables color temperature and brightness to be adjusted in energy-saving mode based on system requirements.
/The light has integrated IP digital audio with adaptive volume control based on the needs of the central control system.
/Installation: flange base installation with an embedded foundation
● Main Materials
/The lamp head and wave-pattern structure are constructed from high-precision integrated aluminum alloy casting, while the lamp body is primarily composed of metal tubing. The surface is secured with 304 stainless steel fasteners and has a premium AkzoNobel glittering silver-gray finish that is resistant to discoloration for five years.
