Abstract

A long-life and energy-saving table lamp comprises a lamp base, LED high-brightness light-emitting diodes and a lampshade. The lamp holder (1) is equipped with a hose (2), the upper end of the hose is equipped with a lampshade (3), and the lampshade is equipped with an LED board (6) formed by connecting a white high-brightness light-emitting diode (4) and a current limiting resistor (5) in series. ). The utility model overcomes the incandescent lamps currently sold in the market, which have low utilization rate of electric energy and short service life of bulbs. Although fluorescent lamps are claimed to be energy-saving and have a long service life, in fact the life of the lamp tube is only about one year, and the ballast or other electronic components also consume insufficient power. Because the utility model adopts white high-brightness light-emitting diodes with low power consumption in series as the light source, ballasts, sockets and other electronic components are omitted, production costs and damage probability are reduced, and the utility model has the advantages of long service life and energy saving.

Description

Longevity Energy Saving Desk Lamp

Technology area

The utility model relates to the lighting field, in particular to an energy-saving desk lamp with long service life.

Background technique

At present, the desk lamps sold in the market generally use incandescent lamps or fluorescent lamps as light sources, and its disadvantages are: the utilization rate of electric energy of incandescent lamps is low, a large part of electric energy becomes heat energy and is wasted in vain, and the service life of bulbs is short. Although fluorescent lamps are claimed to be energy-saving and have a long service life, in fact the life of the lamp tube is only about one year, and the ballast or other electronic components are also consuming electricity. So far, no real long service life, energy-saving desk lamp comes out.

Contents of the invention

In order to overcome the above problems, the utility model provides a desk lamp with long service life and energy saving. In order to achieve the above object, the technical solution of the utility model is: a long-life energy-saving desk lamp, which includes a lamp holder, LED high-brightness light-emitting diodes, and a lampshade. It is characterized in that: a hose is installed on the lamp holder, a lampshade is arranged on the upper end of the hose, and an LED board composed of a white high-brightness light-emitting diode and a current-limiting resistor connected in series is arranged in the lampshade. The power control switch is mounted on the lamp holder.

Significant effect: Since the utility model adopts white high-brightness light-emitting diodes with low power consumption connected in series as the light source, ballasts, tube sockets and other electronic components are omitted, production costs and damage probability are reduced, and it has long service life and energy saving. advantage.
