Abstract

A light-emitting diode (LED) bulb with a universal serial bus (USB) interface comprises an LED light source, a printed circuit board (PCB), a bulb outer shell and the USB interface. The LED light source is welded on the PCB. The USB interface is connected with the LED light source through the PCB. The LED light source and the PCB are arranged in the bulb outer shell, and USB interface is fixedly arranged on the bulb outer shell. The LED bulb with the USB interface is simple in structure, light in weight, wide in using environment, and strong in practical applicability.

Description

A kind of LED bulb with USB interface

Technical field

The utility model relates to a kind of LED bulb, relates in particular to a kind of LED bulb with USB interface.

Background technology

Along with the development of science and technology, the luminous intensity of LED has had large increase, has possessed the requirement of illumination.The LED bulb will replace gradually traditional incandescent lamp, halogen tungsten lamp, fluorescent lamp and HID lamp etc., and becomes the Novel illumination lamp source owing to have the advantages such as power consumption is little, the life-span long, reaction is fast, volume is little, anti-weather.

Existing LED bulb generally comprises screw socket, wiring board, power pack, radiator, heat conductive pad and lamp holder; Lamp holder comprises mount pad, metallic plate, led light source and lens; Led light source is installed on the metallic plate, and the positive and negative lead-in wire that screw socket is drawn by wiring board is connected with led light source, normally take the 220V interchange as power supply.

But existing LED bulb structure is complicated, connects AC power by screw socket, and inside converts alternating current to led light source required direct current by power pack, has both increased the cost of LED bulb, has also limited the environment for use of LED bulb simultaneously.

Summary of the invention

Defective for prior art, the purpose of this utility model is to provide a kind of LED bulb with USB interface, use USB interface to replace the screw socket structure of conventional bulb in some places with USB power supply, make the environment for use of LED bulb more extensive, have very strong practicality and security.

To achieve these goals, the LED bulb with USB interface that the utility model provides comprises, led light source, PCB wiring board, bulb shell, and USB interface, wherein,

Described led light source is welded on the described PCB wiring board, and described USB interface is connected with described led light source by the PCB wiring board, and described led light source and described PCB wiring board place described bulb shell inner, and described USB interface is fixedly mounted on the described bulb shell.

Wherein, have one or more led light sources at described LED bulb.

Wherein, described USB interface is A size USB interface or mini USB interface.

The utility model has following advantage and technique effect:

1) adopt USB interface as the power interface of bulb, because of the output voltage of USB relatively near the supply voltage of led light source, so the power-switching circuit of bulb inside is fairly simple and efficient, can reduce the volume of LED bulb, provide cost savings;

2) adopt USB interface directly to link to each other with bulb shell, consist of complete bulb on the ordinary meaning, use more convenient;

3) because USB interface is to adopt direct current 5V power supply, has unrivaled security advantages.

Other features and advantages of the utility model will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in the specification of writing, claims and accompanying drawing.
