- Patent registration : No. 10-1209903
- Name : Bug control LED light equipped with optical directional reflecting blocks to prevent light pollution
This invention uses optical reflecting members where eccentric reflecting blocks and/or symmetric reflecting blocks with composition of this invention are properly arranged to diverse types of local roads like narrow residential roads with width shorter than 10 meters, T or L shaped roads, dead end alleys; effectively prevents light pollution irradiated from neighboring residential areas; effectively resolves the problem that illumination becomes low at bent roads or the end of dead end alleys; also has an effect to reduce the number of street light by using LED street lights of this invention even though local roads are connected diversely in T/L/I shapes.
Light pollution is a phenomenon that unnecessary or more than necessary artificial light damages human body or natural environment. As industry develops, the damage on human bodies or living things is called pollution. Excessive use of light can also be called pollution.
For pleasant and comfortable night for residents / For normal growth of wild animals and plants / To meet a bright starry night sky / Capable of throwing a light on the section necessary for safe, reasonable energy use / without unpleasant dazzling / with less light upward / with high energy saving effect
In the first contest for "The prize of Good Light from the Seoul Metropolitan City" hosted by the Seoul Metropolitan City, GA Co., Ltd. was awarded the prize in the manufacturing area.
We will always make efforts for our children to see star light in the night sky and good light. We deliver good light to the world.
The invention refers to LED street light illumination control system: in more detail, Energy saving LED street light illumination control system using power line communication efficiently controlling on/off and illumination of LED street light
Power line communication (PLC) is a communication method to send and receive data using an electric line distributed for power supply. GA C., Ltd. accomplished energy saving more efficient than the exiting LED light by applying dimming control system using a PLC and controlling illumination as much as necessary at the desired time. Installation case for Wooyuichon walking trail in Gangbuk-gu, Seoul shows the necessity of PLC dimming control system for energy saving.
LED lights were replaced to care about citizens. Ecosystem conservation/ Planting effect of 4,481 trees with over 84% reduction of energy, brighter light by two times, and reduction of carbon dioxide 53 ton/ Positioning as a benchmarking model case for other cities and provinces
