Description

Semiconductor Energy Saving Light Bulbs

The utility model relates to an energy-saving bulb, in particular to an energy-saving bulb formed by serially connecting semiconductor light-emitting diodes.

Hotels, hotels, and entertainment places use incandescent bulbs for lighting or indicator lights. Because they are continuously lit for a long time, they are often easy to burn out. It is a waste of manpower and material resources to replace them. In addition, incandescent bulbs consume more power, which often easily causes unnecessary waste.

The purpose of the utility model is to develop an energy-saving light bulb, which can not only save electric energy, but also greatly increase its service life.

In order to achieve the above purpose, the utility model is designed to be composed of the lamp holder of the incandescent bulb, the glass bulb and the illuminant. Connect to the positive and negative poles of the output terminals of the semiconductor rectifier bridge stack respectively, one input terminal of the rectifier bridge stack is connected to one of the connection terminals of the lamp cap, and the other input terminal is connected to the other connection port of the lamp cap through a step-down capacitor. In order to prevent the voltage of the input illuminant from being too high, a piezoresistor can be connected between the two input terminals of the rectifier bridge stack.

The usage method of the semiconductor energy-saving lamp is exactly the same as that of the common incandescent lamp. Although the brightness is lower than incandescent bulbs, its continuous service life is as long as 50,000 to 100,000 hours, and its power consumption is less than one watt (about 0.6 watts). It is a real long-life energy-saving lamp.
