Description

A kind of LED desk lamp

technical field

The utility model relates to the technical field of lighting, in particular to an LED table lamp.

Background technique

Light-emitting diodes are referred to as LEDs for short. Diodes made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. Used as indicator lights in circuits and instruments, or composed of text or digital displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED. Light-emitting diodes can also be divided into ordinary monochromatic light-emitting diodes, high-brightness light-emitting diodes, ultra-high-brightness light-emitting diodes, color-changing light-emitting diodes, flashing light-emitting diodes, voltage-controlled light-emitting diodes, infrared light-emitting diodes, and negative resistance light-emitting diodes. There are two kinds of LED control modes, constant current and constant voltage, and there are many dimming methods, such as analog dimming and PWM dimming. Most LEDs use constant current control, which can keep the LED current stable and not easily affected. The change of VF can prolong the service life of LED lamps.

Desk lamp is a kind of lamp. This electrical appliance is mainly placed on the desk or dining table for lighting. The light exposure range of desk lamp is relatively small and concentrated, thereby can not affect the light of whole room, and effect is limited around desk lamp, is convenient to read, study, saves energy, and desk lamp is a kind of household appliance that is used for lighting in people's life. It is generally divided into two types, one is column type, and the other is sandwich type. Its function is to concentrate the light in a small area, which is convenient for work and study. However, the currently used desk lamps all have a lamp holder and a lamp tube, so when used in dormitories, the quantity is large, which will increase the purchase cost and use cost, and has no self-power generation function. Therefore, in order to solve the above problems, a new technical solution is provided.

Contents of the invention

The purpose of the utility model is to provide an LED desk lamp in order to overcome the deficiencies of the prior art.

The utility model is realized through the following technical solutions:

An LED desk lamp, comprising a base, a power switch is provided on the base, a first support arm is provided on both sides of the base, a hinge ball is provided on the upper end of the first support arm, and a hinge ball is provided on the outside of the hinge ball. There is a rotating sleeve, the rotating sleeve is connected with one end of the second support arm, the other end of the second support arm is connected with the lighting lamp body, a vertical pole is arranged in the middle of the base, and the upper end of the vertical pole is provided with Photovoltaic panels arranged at an angle.

As a preferred technical solution of the utility model, the lower end of the first support arm is hingedly connected to the base.

As a preferred technical solution of the present invention, the second support arm is hingedly connected to the lighting lamp body.

As a preferred technical solution of the present invention, the angle between the inclined surface of the photovoltaic panel and the horizontal plane is 30°-90°.

Compared with the existing technology, the beneficial effect of the utility model is: the utility model is simple in structure and reasonable in design, and the utility model can realize arbitrary angle adjustment of the lighting lamp body by setting a hinged ball and a rotating sleeve, which is convenient to use and practical Good performance; by setting two lighting lamp bodies, it is convenient for students in the dormitory to share one base, which is convenient to reduce the number of lamps and reduce costs. At the same time, the lighting lamp body can realize the adjustment of lighting height and angle, and is easy to use.
