Abstract

A light emitting diode (LED) lighting system having a gas detection function may be used not only for lighting but also for detection of volatile organic compounds (VOCs) causing the sick house syndrome at home and other odorless and colorless non-combustible gas harmful to a human body. The LED lighting system may be used as an optical sensor showing with the fast response time and high sensitivity with respect to an environment harmful to a human body. In addition, since the presence of gas can be easily detected through a change of color in comparison to sound alarms for fire and gas contamination, emergency situations can be effectively handled.

First claim

What is claimed is:

1. A light emitting diode (LED) lighting system comprising:
a gas sensing apparatus including a substrate, a sensor electrode mounted on the substrate, and a sensing unit connected to the sensor electrode and made of a metal oxide; and
an LED package to control intensity of emitted light by a voltage controlled through the gas sensing apparatus, wherein the LED package comprises:
an LED chip configured to generate light;
a phosphor layer disposed on the L…
