Description

A kind of illuminating lamp of improved band USB interface

Technical field

The utility model belongs to the illuminating lamp field, relates to a kind of illuminating lamp of improved band USB interface specifically.

Background technology

At present, people use notebook computer under night or open-air dark surrounds, be difficult to identify the definite position of letter on the keyboard, this has brought inconvenient part to the user, at this type of problem, a kind of illuminating lamp with USB interface has appearred, its principle utilizes computer USB interface 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, and the weak point of this illuminating lamp is for can't regulate brightness, switch lamp need carry out the plug of USB, and is not too convenient.

Summary of the invention

The utility model provides the illuminating lamp of the band USB interface of a kind of improved Convenient switch, adjustable brightness for overcoming shortcoming of the prior art.

The utility model is achieved by following technical scheme:

A kind of illuminating lamp of improved band USB interface, comprise the lighting circuit that constitutes by a luminous tube LED and resistance at least, lighting circuit is provided with the USB interface plug that can be connected with the computer USB socket, described luminous tube LED two ends shunt capacitance, described lighting circuit and can and the USB interface plug that is connected of computer USB socket between be provided with variable resistor and switch.

The illuminating lamp of described improved band USB interface, its lighting circuit is made of 1-5 group resistance R and luminous tube LED and the electric capacity that is connected in parallel on luminous tube LED two ends.

The advantage that the utility model compared with prior art has is, owing between lighting circuit and USB interface plug, be provided with variable resistor and switch, so both can regulate the brightness of light, also switch at any time, the convenient use is like this when using computer night, light among a small circle just can be provided, thereby cosily operation keyboard does not influence others and can not bother, and has made things convenient for work and life.

Description of drawings

Fig. 1 is circuit theory diagrams of the present utility model.

Embodiment

The utility model is further described below in conjunction with accompanying drawing:

As shown in Figure 1, a kind of illuminating lamp of improved band USB interface, comprise the lighting circuit 1 that constitutes by a luminous tube LED and resistance R at least, lighting circuit 1 is provided with the USB interface plug 2 that can be connected with the computer USB socket, luminous tube LED two ends shunt capacitance C, lighting circuit 1 and can and the USB interface plug 2 that is connected of computer USB socket between be provided with variable resistor R1 and switch 3, switch 3 is connected with lighting circuit with resistance R 1.

Lighting circuit 1 is made of 1-5 group resistance R and luminous tube LED and the capacitor C that is connected in parallel on luminous tube LED two ends.

During operating computer, open switch 3 under night or the dark surrounds, regulate variable resistor R1 after be fit to brightness, but operating computer just.
