Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, and more specifically, to an LED lamp bar structure. Background Art

[0002] With the rapid development of science and technology, LED backlight technology has been widely used in the field of display technology due to its advantages of high efficiency, energy saving and environmental protection. However, there is a significant problem in the use of traditional LED backlight strips, that is, uneven brightness. This problem mainly stems from the direct irradiation and reflection between LED lamp beads, which makes the light distribution at a specific position uneven, seriously affecting the uniformity and comfort of the lighting effect.

[0003] In traditional LED backlight solutions, LED lamp beads are usually directly arranged on the light bar, and effective isolation measures are not determined. This causes the light emitted by the LED lamp beads to interfere with each other during the propagation process, forming obvious bright and dark areas. Especially in applications such as liquid crystal display devices, this uneven brightness is particularly prominent, which not only affects the user's visual experience, but may also have an adverse effect on the user's eyesight. Because we have improved this, we proposed an LED light bar structure.

[0004] For example, a Chinese patent (publication number CN111965751B) discloses a high-reflectivity LED backlight source for micro displays, and its specification discloses: Nowadays, many electronic products are integrated into people's lives, such as the most common mobile phones, computers, televisions, etc., so the demand for backlight sources is increasing. At present, there are three types of backlight sources, EL, CCFL and LED, and LED backlights are now favored by the market for their unique characteristics such as high photoelectric conversion efficiency, high color saturation, small size, impact resistance, low-voltage power supply, and long life, and the demand is also increasing. The backlight source is mainly composed of a light source, a light guide plate, an optical film, and structural parts. The optical film includes a light-enhancing film, a diffuser, and black and white glue. The black and white glue is mainly used to prevent light from escaping from the edge of the backlight source. The LED backlight sources before all use LED point light sources. The divergent characteristics of point light sources make the light partially lost before passing through the light guide plate and the optical film, that is, the light source cannot be fully irradiated on the optical film, and the brightness of the irradiation is also uneven due to the divergent characteristics of the light source itself and the interference between adjacent light sources. The above patents can prove the defects of the existing technology. Utility Model Content
