Negative ion air purifying energy saving lamp

The utility model relates to a negative ion air purifying energy saving lamp which comprises a lamp cap (1), an energy-saving lamp tube (5) and an anion generator (4), wherein the energy-saving lamp tube (5) is inserted in the lamp cap (1), and is connected with a voltage transformation circuit board (2) which is arranged in the lamp cap (1); the anion generator (4) is inserted into the lower bottom surface of the lamp cap (1), and is extended to the voltage transformation circuit board (2) to be electrically and integrally connected with the voltage transformation circuit board (2). The utility model is characterized in that a starter (3) which can quickly generate lots of negative ions is arranged on the voltage transformation circuit board (2), and the starter (3) is electrically connected with the anion generator (4). The utility model has the advantages that a starter (3) is arranged on the voltage transformation circuit board (2), and thus the starter is worked when the energy saving lamp is opened; consequently, the anion generator can quickly generate a lot of negative ions in a short time, and the purposes of removing smoke smell and strange smell and killing bacteria to purify indoor air is better obtained; thus, the utility model not only has less illumination, less power consumption and energy saving, but also can cause the human body to live in indoor environments with fresh air.
