Description

A light guide plate night light

technical field

The utility model relates to an LED light guide plate, in particular to a light guide plate night light suitable for lighting in dark areas, artistic lighting and decorative lighting. the

Background technique

The design principle of the light guide plate is derived from the liquid crystal display screen of the notebook computer. The light guide plate uses fluorescent lamps, CCFL, and LED light sources to pass through the light guide point or light guide groove calculated according to the optical principle, and under the action of the reflective film (reflector) and the diffusion film, the line light source or point light source is transformed into a surface light source. In order for the light guide plate to emit light evenly, it must pass through various light guide points of different densities and sizes to ensure that the efficiency of light reflection in all directions is basically the same. The purpose of the reflective sheet (reflective plate) is to reflect the light revealed from the bottom surface of the light guide plate back into the light guide plate, so as to improve the efficiency of light use and increase the brightness. Since LED is a point light source, direct use will irritate people's eyes. The existing technology is to transform the point light source into a For surface light source. The function of the diffusion film is to make the light more uniform and softer. The light guide plate has a wide range of applications, such as TV backlight, lighting, decoration, advertisement, signage and so on. However, the existing night lights all use direct-light LEDs and light bulbs, which have poor light emitting effects, dazzling light, and short service life. the

Contents of the invention

In order to solve the technical problems of poor light emitting effect, dazzling light and short service life of the existing small night lights, the utility model proposes a light panel night light with good light emitting effect, soft light emission, long service life, energy saving and environmental protection. the

In order to solve the above technical problems, the utility model proposes a night light with a light guide plate, which includes a light guide plate, a light guide point disposed on one side of the light guide plate, a housing disposed on one side of the light guide plate, and a rectifier disposed in the housing. Transformer circuit, the LED light source connected to the rectifier and transformer circuit arranged on the side of the light guide plate, and the electric pin connected to the mains on the outside of the housing, the electric pin and the rectifier transformer voltage circuit connection. the

The light guide plate is any one of rectangle, star, triangle, circle, ellipse and various three-dimensional shapes. the

The light guide plate is made of any light guide material such as acrylic, glass or PC. the

The light guide point is made by any method of printing, engraving, molding or etching. the

A diffusion film and a reflection film are provided on the front or back of the light guide plate. the

The surface of the light guide plate is provided with transparent, translucent or frosted patterns. the

Compared with the prior art, the utility model has advantages:

1. The existing night lights all use direct-light LEDs and light bulbs, but this utility model emits light through light guides, or is a surface light source, with good light output, soft light, long life, energy saving and environmental protection;

2. The utility model is more artistic, simple in design and easy to use. The product is widely used in various lighting, decorative lighting and other fields. the
