Description

A desk lamp with a USB charging interface

Technical field:

The utility model belongs to the field of daily electrical appliances, in particular to a desk lamp which can simultaneously serve as a USB charging interface (female seat) and has a charging function.

Background technique:

Existing table lamps have various shapes and types, but they are mainly used for lighting and belong to commonly used household appliances.

USB charger is an accessory product of mobile communication, MP3, digital camera and other electronic products. When in use, plug the USB charger into the AC power supply, connect the USB charging power cord adapted to mobile communication, MP3, digital camera and other electronic products to the USB One end of the plug is inserted into the USB charger interface (female socket), and the other end is inserted into the special interface for charging electronic products such as mobile communications to charge, which is also a common household electrical appliance.

When we use these two products at the same time, we need to insert the power plugs of the two products into different power jacks, and then they can be in working condition after being powered on. There are two disadvantages during use, one is that two power jacks are needed; the other is that when the two kinds of electrical appliances are used at the same time, they occupy a part of the space respectively, and the power cords are many and easily messy, which increases the danger of using electricity for users.

Invention content:

The purpose of this utility model is to provide a desk lamp that can be used as a USB charging interface (female seat) at the same time and has a charging function, and can also be used as a desk lamp to provide lighting, decorate and beautify the living room; and the user does not need to carry a larger USB charger. You need to bring a USB charging power cord compatible with mobile communications, MP3, digital cameras and other products, and you can easily charge mobile phones, MP3 and other electronic products; at the same time, only one power jack is used, which reduces the risk of electricity consumption and is convenient for users use.

The utility model is implemented as follows: in the inner cavity of the common desk lamp base, an AC/DC USB charging conversion circuit with a feedback system is set, on the panel of the desk lamp base, an AC power switch of AC/DC is set, and the status Indicator lights, 1 or more USB charging ports (female sockets); the AC power supply of the desk lamp is connected to the USB charging conversion circuit through the charging circuit switch, and the power supply is converted by the USB charging conversion circuit with AC/DC feedback system Converted to 3/5V USB universal voltage. It can be charged by connecting electronic products such as mobile communication and MP3 digital camera; the charging indicator will prompt the charging status of the battery.

The utility model adopts a power plug and a power cord, which can realize the use function of an ordinary desk lamp and a USB charger. At the same time, the USB charger is arranged in the inner cavity of the desk lamp base, which is beneficial to increase the stability of the desk lamp and save materials; It is convenient to use the USB interface (female seat) to charge.

Description of drawings:

Accompanying drawing 1 is the internal circuit schematic diagram of the utility model.

Accompanying drawing 2 is the three-dimensional combined exterior view of the utility model.

Accompanying drawing 3 is the front view of the utility model.

Accompanying drawing 4 is the embodiment diagram of different appearances of the utility model applied to desk lamps.

Detailed ways:

The utility model is described in further detail below in conjunction with the accompanying drawings.

Please refer to accompanying drawing 1 and accompanying drawing 2, the utility model includes: a power plug 100, power cord 101, desk lamp base 102, desk lamp lighting switch 103, desk lamp luminous light source bracket 104, desk lamp luminous light source 105, desk lamp lampshade 106; In the inner cavity of the desk lamp base, an AC/DC USB charging conversion circuit 203 with a feedback system is provided; on one plane of the desk lamp base, there are respectively provided with: an AC power supply of an AC/DC USB charging conversion circuit with a feedback system The switch 201, the AC power indicator light 202 of the charging conversion circuit, the USB charging interface (female seat) 204 and the indicator light 205 for prompting the working state of the USB charging interface (female seat).

After the AC power plug 100 of the desk lamp is inserted into the AC power supply and turned on, the AC power supply is input to the inside of the desk lamp base 102 by the power cord 101, and two parts of the power supply are connected. The charging power switch 201 and the charging AC power indicator light 202 are input to the USB charging conversion circuit 203 with AC/DC feedback system, which is converted into 3/5V by the charging circuit 203 to adapt to mobile communication, MP3, digital camera and other electronic products charging Voltage, through the USB charging interface base 204, connect mobile communication, MP3, digital camera and other products with the corresponding USB charging power line 301, and then charge; , indicating the charging status of the battery. The charging power switch 201 can control the power of the entire charging circuit. When the charger is not in use, turn off the charging power switch 201 to prevent the charging circuit from being turned on for a long time, wasting electric energy and working for a long time to damage the charging circuit.

Please refer to accompanying drawing 3 and accompanying drawing 4, the illuminating light-emitting part of desk lamp of the present utility model can be adopted to be common bulb, also can be the form such as energy-saving lamp, fluorescent lamp, LED, the connection part structure of supporting the illuminating of desk lamp, can be elastic The curved shape can also be a rigid rod shape or a telescopic adjustable shape; combined with the USB charging function, it can make the desk lamp more useful and richer in shape.

In general, besides lighting, the desk lamp of the present utility model also has the function of USB charging output, which saves space and improves the safety of electricity consumption. The USB charging power cord 301 of electronic products such as digital cameras can easily complete the charging.
