1. An electronic cigarette, comprising:
- a housing;
a control circuit electrically connected to an airflow sensor in the housing;
a light source at a first end of the housing, with the light source electrically connected to the control circuit, and with the light source configured to provide a gradual change in luminance via control by the control circuit, when the airflow sensor senses airflow, to simulate a conventional cigarette.

Abstract
An electronic cigarette comprises nicotine without harmful tar. The cigarette includes a shell, a cell, nicotine solution, control circuit, and an electro-thermal vaporization nozzle installed in the air suction end of the shell. The advantages of the present invention are smoking without tar, reducing the risk of cancer, the user still gets a smoking experience, the cigarette is not lit, and there is no fire danger.
