Description

TECHNICAL FIELD

The present disclosure relates to a technical field of spiral lamp caps, and in particular to a light bulb.

BACKGROUND

At present, Light Emitting Diode (LED) bulbs are generally divided into two types, and a first type of the LED bulbs is light bulbs powered by Alternating Current (AC) mains. In the first type, two contacts of the LED bulbs powered by the AC mains are disposed on a bulb body, one of the two contacts is connected to an AC mains supply fire line, and the other one of the two contacts is connected to an AC mains supply zero line. The LED bulbs powered by the AC mains contains a driver, and overall temperature of the LED bulbs powered by the AC mains is increased due to heat dissipated by the driver. This type of the LED bulbs powered by the AC mains can be made into two-color dimmable light bulbs, but a production scheme is complex and production cost is high.

A second type of the LED bulbs is low-voltage bulbs. The low-voltage bulbs comprise two contacts, and one of the two contacts is connected to a positive terminal of a direct current (DC) power supply and the other one of the two contacts is connected to a negative terminal of the DC power supply. A power supply of the low-voltage bulbs does not contain the driver. Since the low-voltage bulbs have only the two contacts, only one path of lamp beads is installed in the low-voltage bulb, that is, the low-voltage bulbs only emits light of one color, which cannot meet requirements of being made into the two-color dimmable light bulbs
