Description

Page Flip Rechargeable LED Desk Lamp

technical field

The utility model relates to a daily necessities, in particular to a page-turning rechargeable LED desk lamp.

Background technique

In recent years, LED desk lamps have become more and more popular in the market due to their advantages of low working voltage, low energy consumption and high brightness. Most of the existing LED desk lamps are often directly connected to the 220V voltage through the power interface, so they are only suitable for indoor use, and cannot continue to illuminate when the power is cut off.

In order to solve the problem of not being able to continue lighting due to power outages, new portable and rechargeable LED desk lamps have begun to appear. Inside these table lamps are rechargeable batteries, and the charging method is still directly charged with 220V voltage. Taking the patent CN202580857U as an example, this type of LED desk lamp is often small in size, can be folded, and can last after being fully charged. However, these LED desk lamps have a shortcoming. When the battery power is exhausted, the charging interface must be directly connected to the 220V voltage to charge. The charging method is relatively simple and cannot meet some needs of real life.

In order to diversify the charging methods, LED desk lamps with USB charging have begun to appear, such as patent CN203147576U. This new type of LED desk lamp enables charging to be completed at a lower voltage. For example, through the USB interface, the desk lamp can be charged with a power bank, which greatly facilitates real life.

Although there are diversifications in the charging methods, due to the failure to optimize the structure of the foldable LED desk lamp, in reality most of the foldable desk lamps are often relatively thick after being folded, which is inconvenient to carry. At the same time, the existing foldable desk lamps can only be used on a horizontal plane, and when there is no horizontal plane, it is often difficult to place them. In order to solve these problems, the utility model optimizes the structure of the foldable LED desk lamp, and changes the original superposition on a single surface to be scattered on the same surface, so that the thickness of the foldable backlight is greatly reduced. At the same time, various charging methods and automatic brightness adjustment can bring users a better user experience.

Contents of the invention

The purpose of the utility model is to provide a page-turning rechargeable LED desk lamp, which has diversified charging methods, energy saving and environmental protection, novel design, convenient portability and good user experience.

The technical scheme of the utility model is: a page-turning rechargeable LED desk lamp, which is characterized in that it includes a panel and a foldable lampshade; on the inner surface of the foldable lampshade, there are patch LED lamps; the panel consists of a panel inner shell It is packaged with the panel shell; the lithium battery, neodymium magnet, circuit board, USB charging port and main switch are fixed on the panel inner shell; when the panel is opened gradually, the foldable lampshade unfolds gradually, and the magnets in each page The reed switch works step by step to automatically light up the LED light, so that the brightness can be automatically adjusted with the different opening angles of the panel; the USB charging port can charge the lithium battery and provide power for the desk lamp.

Above-mentioned technical scheme is further explained below:

The panel is encapsulated by a panel inner shell and a panel outer shell, and the panel inner shell and the panel outer shell are made of materials with certain strength, such as plastics and wood boards. In order to reduce the thickness of the panel, the thickness of the inside and outside of the panel should be as thin as possible.

The panel can be unfolded in the range of 0 to 360 degrees like the upper and lower covers of a book.

The inner panel shell and the outer shell of the panel should be insulated to prevent electric leakage and fixed by buckles.

The panel inner shell has two sides, one is the closed surface connected with the foldable lampshade, and the other is the non-closed surface connected with the panel shell.

A lithium battery, a neodymium magnet, a circuit board, a USB charging port and a master switch are fixed on the non-closed surface of the inner shell of the panel.

The lithium batteries, neodymium magnets, and circuit boards should be thinner.

The lithium battery, the circuit board, the USB charging port and the main switch are connected through a circuit, so that the lithium battery can be charged through the USB charging port, the circuit board can make the LED light work normally, and the main switch can control the on and off of the entire circuit .

The foldable lampshade can be folded and compressed, has higher flexibility and thinner thickness, can be unfolded with the panel, and can see through the light of the patch LED lamp.

The patch LED lamp is glued to the inner surface of the foldable lampshade, and the patch LED lamp is controlled through a circuit board.

There is a magnetic reed switch in each page of the foldable lampshade, and the reed switch is connected in series with the LED lamp through a circuit. .

The magnetic reed switch is composed of two parts, one part is a dry reed switch located in the foldable lampshade, and the other part is a magnet located on the closing surface of the panel inner shell.

The neodymium magnets are fixed on the four corners of the non-closed surface of the inner shell of the panel, which can attract the panel to the surface of the metal object, and can also attract two by two of the panel when the panel is unfolded to 360 degrees.

The utility model has the advantages that the page-turning rechargeable LED desk lamp has the biggest features: 1. USB charging and lithium battery power supply. The use of USB charging makes the charging method of the desk lamp diversified. For example, it can be connected to a computer USB port, a power bank port, etc., and a charging head can also be used to realize direct 220V voltage charging. The lithium battery power supply can prolong the battery life of the LED desk lamp to the greatest extent, and at the same time, its lighter weight can reduce the weight of the desk lamp.

2. Thinner, automatic dimming, higher brightness under the same conditions. Since thinner materials are used in the design, and a lot of SMD LED lights can be placed in one lampshade, it is thinner than traditional foldable LED desk lamps under the same volume and can emit brighter lights. Light. Because there is a magnetic reed switch in each page of the folding lampshade, the LED desk lamp will automatically light up as the panel is opened, and the brightness will be automatically adjusted according to the degree of panel opening, which has a good user experience.

3. Can be used under various conditions. Due to the strong suction neodymium magnet inside the panel, the desk lamp can be easily attracted to the surface of metal objects. For the surface of non-metallic objects, the panel itself can stand steadily at a certain angle after being turned over, providing all-round lighting.

4. Energy saving and environmental protection. Using LED lights, it is more energy efficient than traditional desk lamps. At the same time, the design of the magnetic reed switch in the foldable lampshade enables the panel to light up different numbers of LED lights at different unfolding angles, instead of lighting all of them at once, which can make the desk lamp more energy-efficient.
