Abstract
The invention discloses a novel backlight module with hybrid application lenses. The novel backlight module comprises a back panel and LED (Light Emitting Diode) light bars which are arranged on the back panel in parallel, wherein LED lamp beads are uniformly arranged on the LED light bars and are covered by lenses which comprise diffusion reflection lens and refraction lenses; a roughly equal number of diffusion reflection lens and refraction lenses are arranged on the same light bar. According to the novel backlight module, the diffusion reflection lens and the refraction lenses are applied on the same light bar in a hybrid manner; through match of the two lenses, the light can realize more complex irregular diffusion and can be more uniformly transferred to a position with a wider range, and the light emission effect of the backlight module is better.
Description
Technical field
The present invention relates to flat panel TV backlight technology, be specifically related to a kind of backlight module.
Background technology
Backlight module is the important component part of flat panel TV, and the correlated performance of some indexs such as its brightness, uniformity etc. on flat panel television display screen has direct impact.Backlight module is primarily of compositions such as backboard, LED lamp bar and lens, and lens jacket is located on the lamp pearl of LED lamp bar, plays diffusing light, light is acted on more uniformly.Traditional backlight module is all generally adopt single lens, namely single module only can contain diffuse reflection lens or refractor, the diffusion way of light is single, not evenly.
Summary of the invention
In order to solve above technical problem, the invention provides the novel backlight module of a kind of lens mixing application, the diffusion of its light is various, and range of exposures covers comprehensively, brightness uniformity.
The technical scheme that the present invention adopts for technical solution problem is:
A kind of novel backlight module of lens mixing application, comprise backboard and the parallel LED lamp bar be installed on backboard, described LED lamp bar is evenly provided with LED lamp bead, LED lamp bead is coated with lens, described lens comprise diffuse reflection lens and refractor, diffuse reflection lens set on same lamp bar and refractor quantity roughly equal.
As preferred embodiment, the diffuse reflection lens on same lamp bar and refractor interlaced arrangement.
The invention has the beneficial effects as follows: the present invention mixes and applies diffuse reflection lens and refractor on same lamp bar, under the cooperation of two kinds of lens, light can carry out more complicated irregular diffusion, light can more uniformly be delivered to wider position, and the illumination effect of backlight module is better.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the structural representation of the first embodiment of LED lamp bar;
Fig. 3 is the structural representation of LED lamp bar the second embodiment.
Symbol description: 1-backboard, 2-LED lamp bar, 3-lens, A-diffuse reflection lens, B-refractor.
Detailed description of the invention
As shown in Figure 1, backlight module of the present invention forms primarily of backboard 1, LED lamp bar 2 and lens 3.LED lamp bar 2 is parallel to be installed on backboard 1, is evenly provided with LED lamp bead above it.Lens 3 are covered in LED lamp bead.The present invention is configured with diffuse reflection lens and refractor in same LED lamp bar 2 simultaneously, and under the cooperation of two kinds of lens, light can carry out more complicated irregular diffusion, and light can more uniformly be delivered to wider position.In order in order to be effective, the diffuse reflection lens in same LED lamp bar 2 and the quantity of refractor should be roughly equal, so-called roughly equal, namely when LED lamp bead quantity is even numbers, both quantity is equal, and when for odd number, wherein a kind of number ratio another kind of lens has more one.Fig. 2 and Fig. 3 is the lens kind schematic diagram that same lamp bar adopts, and wherein A is diffuse reflection lens, and B is refractor.The mode of what embodiment wherein in Fig. 2 adopted is diffuse reflection lens and refractor interlaced arrangement, can reach good light diffusion effect.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. the novel backlight module of a lens mixing application, comprise backboard and the parallel LED lamp bar be installed on backboard, described LED lamp bar is evenly provided with LED lamp bead, LED lamp bead is coated with lens, it is characterized in that: described lens comprise diffuse reflection lens and refractor, diffuse reflection lens set on same lamp bar and refractor quantity roughly equal.
2. the novel backlight module of a kind of lens mixing application according to claim 1, is characterized in that: the diffuse reflection lens on same lamp bar and refractor interlaced arrangement.
