Abstract
The utility model relates to an illuminating lamp with a USB interface, which comprises an illuminating circuit which is composed of luminous pipes and resistors. The utility model is characterized in that the illuminating circuit is provided with a USB interface plug which can be in matching connection with a USB jack of a computer. The power input end of the circuit of an ordinary DC illuminating lamp is provided with a plug which be in matching connection with the USB jack of the computer, which make full use of the characteristic that the USB interface of the computer can be used for data transmission and power supply, and batteries which are used for operation of the computer supply power for the illuminating lamp through the USB interface which is arranged on the circuit of the DC illuminating lamp. The utility model can provide illumination in a small range for operating the computer of people in night or dark environment so that people can comfortably and freely operate a keyboard of the computer under soft and white light. The illuminating lamp with USB interfaces is particularly suitable for matching with a portable computer to be used outdoors.
Description
Technical field
The utility model relates to illuminating lamp, especially a kind of illuminating lamp with USB interface.
Technical background
At present, the illuminating lamp kind of selling on the market is a lot, and having with the alternating current is the light fixture of power supply, and also having with the battery is the light fixture of power supply.The basic function of light fixture provides illumination for people exactly under night or dark surrounds, with life, the study and work that is convenient for people to.
Summary of the invention
The purpose of this utility model provides a kind of illuminating lamp that computer is equipped with the band USB interface of using that is used for.
The illuminating lamp of the utility model band USB interface comprises: the lighting circuit that is made of a luminotron and resistance at least is characterized in that: lighting circuit is provided with the USB interface plug that can be connected with the computer USB socket.
The illuminating lamp design concept of the utility model band USB interface is: at general dc lighting circuit for lamp power input one plug that can be connected with the computer USB socket is installed, make full use of computer USB interface and not only can transmit data, and the characteristics that can power, by being arranged on the USB interface on the dc lighting circuit for lamp, the battery that is moved by the power supply brain provides power supply for illuminating lamp.
The illuminating lamp design science of the utility model band USB interface, simple in structure, the illuminating lamp volume of this band USB interface is little, easy to carry.It can be operating computer in people's night or the dark surrounds among a small circle light is provided, to be convenient for people to the comfortable keyboard of operating computer freely under soft white light.The illuminating lamp of this band USB interface especially is fit to laptop computer supporting use out of doors.Because the illuminating lamp light scope of band USB interface is controlled easily, it uses the work that had both made things convenient for the computer operator, can infectively not live again.And has good energy-saving effect.
The concrete structure of the illuminating lamp of the utility model band USB interface is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the illuminating lamp electricity theory structure synoptic diagram of band USB interface;
Fig. 2 is another structural principle synoptic diagram of the illuminating lamp electricity of band USB interface.
Embodiment
Embodiment 1: can be clear that from Fig. 1, the lighting circuit 1 of the illuminating lamp of band USB interface is identical with general lighting circuit, resistance R by luminotron LED and serial connection constitutes, and lighting circuit 1 is connected to a USB interface plug 2 that can be connected with the computer USB interface inserting.
Embodiment 2: can be clear that from Fig. 2 this is the illuminating lamp of a high light type band USB interface, lighting circuit 1 is made of three groups of resistance R and luminotron LED, the capacitor C that is connected in parallel on luminotron LED two ends.Lighting lamp circuit 1 is connected to a USB interface plug 2 that can be connected with the computer USB interface inserting.
Claims (2)
