Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] Such as Figure 4-5 As shown, the light-emitting device provided by the present invention includes: a base 1 and a plurality of light-emitting units. The base 1 is provided with slide rails, and the light-emitting units can slide on the slide rails. Adjacent light-emitting units are connected by flexible wires. Wherein, the flexible wire can be bent arbitrarily.

[0034] By arranging a plurality of light-emitting units to slide arbitrarily on the slide rail and cooperating with flexible wires that can be bent arbitrarily, the distance between adjacent light-emitting units can be adjusted arbitrarily, the structure is simple, the operation is convenient, the product...

Abstract

The invention relates to the technical field of luminous source equipment, in particular to a light-emitting device with adjustable LED (Light-Emitting Diode) lamp intervals. The light-emitting device comprises a base and a plurality of light-emitting units, wherein the base is provided with a slide rail; the light-emitting units can move on the slide rail; and adjacent light-emitting units are connected with one another through flexible leads. According to the light-emitting device provided by the embodiment of the invention, the light-emitting units slide optionally on the slide rail, and the flexible leads which can be bent optionally are adopted simultaneously in a matching way, so that the intervals between adjacent light-emitting units can be adjusted optionally; the light-emitting device is simple in structure, and is convenient to operate; and the production cost is lowered, and the dimming efficiency can be increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light-emitting device with adjustable spacing between LED lamps, a backlight module and a display device using the light-emitting device. Background technique [0002] Because LED (Light Emitting Diode, light-emitting diode) has many advantages such as high brightness, high color purity, long life, good reliability, and no mercury pollution, the proportion of light source in the backlight module is gradually increasing. In the prior art, the direct type backlight module usually arranges the LED light strips evenly on the reflection sheet. Since the energy distribution of the light emitted by the LED is Lambertian, it is concentrated within a certain angle of the optical axis. In order to obtain uniform illumination, it is usually achieved by increasing the number of LED lamps or increasing the light mixing distance of the backlight, which leads to a large number of LED lamps ...
