Description

A kind of LED book light

technical field

The invention relates to an LED lamp, in particular to a portable LED book lamp.

Background technique

Compared with general light sources such as incandescent lamps, LED lights have the advantages of energy saving and long life, so they are becoming more and more common in daily life. Besides being used as fixed light sources, we often encounter When it is necessary to use a portable lamp for lighting, most of the mobile desk lamps on the existing market have defects such as low power, damage to eyes due to concentrated light, short battery backup time, large size and inconvenient to carry, etc., which cannot meet the needs of users.

Contents of the invention

The main purpose of the present invention is to overcome the disadvantages of the prior art above, and provide a portable LED book lamp with soft light and long battery backup time.

The present invention is realized through the following technical solutions. The LED book lamp includes a light source, a lamp holder, a lampshade, and a power supply device. It is characterized in that: the lamp holder includes a cover, a spine and a back cover, and the lampshade is a The inner page combination, the two ends of the inner page combination are glued to the inside of the front cover and the back cover respectively, the middle part of the spine is provided with a light strip with a light source, and the light source light belt is electrically connected to the circuit board and the power supply battery, and the circuit and the power supply device are located at On the inner side wall of the front cover or back cover, the light source with a lamp is connected in series with a sliding dimming resistor, and one end of the pull tab is fixed on the sliding dimming resistor, and the other end is fixed on the center of the spine, and the front or back cover is opened 1~360° In combination, the position of the sliding dimming resistor relative to the center of the spine is also changed, and the pull tab moves on the sliding dimming resistor to change the resistance value and adjust the brightness of the light source.

Furthermore, the inner page combination is formed by bonding the connection surfaces of multiple two adjacent book pages, and the inner page combination can be fan-shaped by 1-360° with the spine as the axis.

Preferably, the power supply device is two power supply lithium batteries arranged on the inner side of the front cover and the back cover respectively.

Preferably, a PCB support is provided at the center of the spine, and the pull-tab is fixed on the top of the PCB support.

Preferably, a mini-socket interface for charging the power supply device is provided on the outside of the spine.

When the book light is turned on, flipping the book cover will touch the switch light set inside to light up, and the lit light source can be illuminated by emitting light from the inside through the pages of the book; it can be turned on at any angle from 1° to 360° to illuminate, and when the book is opened The brightness of the cover gradually changes from dark to bright, and the book case is the brightest when it is opened to 180°. When you need to turn off the light, you can directly close the book cover; when the lamp is out of power, you can directly plug it into the The Mi Er socket on the back of the book case is charged, so that it can be recharged and used.

The invention has the advantages of simple structure, elegant appearance, convenient portability, and long lighting time. The light is scattered through the lampshade shaped like a book page, the light is soft and does not hurt the eyes, and is suitable for users in various occasions.

Detailed ways

The present invention will be further described below in conjunction with the description of specific drawings.

As shown in Figures 1 to 5, the LED book lamp of the present invention is mainly a portable lamp whose external structure is a book. There is a battery 4 on each of the back cover and the back cover, and the battery 4 can be charged through the mini socket 11 arranged in the outer center of the spine 2. The battery 4 is connected to the circuit board 5, and the circuit board 5 is connected in series with the light source with light board 6, and the light source with light board 6 It can be set as two, and there is a PCB bracket 7 in the center of the two light source boards 6, that is, the spine 2. The light source board 6 is connected in series with a dimming resistor 8 arranged on the circuit board 5. The dimming resistor 8 Dimming is performed through a pull bar 9 with one end arranged on the dimming resistor 8 and the other end fixed on the top of the PCB bracket 7 .

As shown in Figure 2, the lampshade is made of an inner page combination 10, the inner page combination 10 is formed by bonding the connection surfaces of a plurality of two adjacent book pages, so that the inner page combination 10 can be carried out with the spine 2 as the axis. ~360° fan-shaped expansion, the combination of 10 internal pages can form a space between the pages of the book that can accommodate light, so that the light can be well scattered, and it is like opening a flipped book when using it. When it opens 360°, it looks like a ring-shaped lantern; the material of the lamp shell, namely the cover, back cover and spine, is wood, which makes it more portable and truly environmentally friendly. Its lampshade, namely the inner page combination 10, is made of imported environmentally friendly wood fiber paper. This kind of fiber paper is a wear-resistant, light weight, breathable and waterproof environmental protection material. The light becomes soft after it is filtered, and the light will not cause irritation when it enters the eyes. None of them have the effect of protecting eyes and health. Taking table lamps as an example, most of them expose the light source or add a transparent cover. Although this increases the brightness of the lamp, it will cause fatigue to the eyes of reading or workers in front of the lamp. Myopia and other damage; the lampshade of this application purchases high-quality imported fiber paper as a material, which is very suitable for reading lighting. Its light is soft and does not hurt the eyes, and its brightness is higher than some professional reading desk lamps on the existing market. It is also better than all It has a function beyond the reach of a desk lamp. It can be combined like a book in size and weight, put it in a bag and take it anywhere. When you need a desk lamp, flashlight, emergency light or camping light, just open this "special book" Can provide 5 hours of lighting continuously.
