Abstract
The utility model discloses a novel saw-tooth structure of a light guide plate for a backlight source, which is arranged on one side of the light guide plate. Saw teeth in the novel saw-tooth structure of the light guide plate for the backlight source are perpendicular to an LED light-emitting surface, contact with the same, and are formed by a plurality of arc-shaped saw tooth units which are connected in sequence. The novel saw-tooth structure of the light guide plate for the backlight source can improve front lighting effect of the backlight source effectively.
Description
Technical field
The utility model relates to a kind of novel backlight source light guide plate broached-tooth design.
Background technology
Present backlight light guide plate broached-tooth design all adopts wedge angle or straight angle structure and since this broached-tooth design to reflection of light, refracting power a little less than, thereby make that effect is relatively poor before the backlight lamp.
The utility model content
The utility model wants the technical solution problem to provide a kind of novel backlight source light guide plate broached-tooth design, and this novel backlight source light guide plate broached-tooth design can effectively improve the preceding effect of backlight lamp.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of novel backlight source light guide plate broached-tooth design, be arranged on a side of light guide plate, sawtooth in this novel backlight source light guide plate broached-tooth design contacts perpendicular to the LED light-emitting area and with the LED light-emitting area, and described sawtooth is connected in sequence by a plurality of circular arc sawtooth unit.
The diameter of each circular arc sawtooth unit is 0.13mm, is spaced apart 0.05mm between the adjacent sawtooth, i.e. straight section 0.05mm between 2 sawtooth.
The beneficial effects of the utility model:
Novel backlight of the present utility model source light guide plate broached-tooth design, sawtooth is positioned over the light guide plate face that light guide plate and LED light-emitting area connect end, the light that LED is sent conducts by refraction, reflection, the scattering process of sawtooth, according to optical principle, light is propagated to another kind of medium from a medium all can produce refraction, reflection, scattering phenomenon, circular arc evenly uses than the light that the sawtooth of wedge angle or straight angle shape can send LED better, thereby novel backlight of the present utility model source light guide plate broached-tooth design can effectively improve effect before the backlight lamp.Effect before the lamp is a quality requirements to backlight product, is after saying that backlight is lighted, and visual before the light source can not have phenomenons such as tangible bright lamp, dark space, the people seem whole luminous evenly, coordinate best.
Description of drawings
Fig. 1 is that the light guide plate and the LED position of band saw toothing concerns synoptic diagram (front view);
Fig. 2 is that the light guide plate and the LED position of band saw toothing concerns synoptic diagram (side view);
Fig. 3 is the enlarged drawing of A part among Fig. 1.
Label declaration: the 1-LED lamp, the 2-light guide plate, 3-circular arc sawtooth unit, among Fig. 1 straight up arrow represent the direction of the light that light source sends.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
As Figure 1-3, a kind of novel backlight source light guide plate broached-tooth design, be arranged on a side of light guide plate, the sawtooth in this novel backlight source light guide plate broached-tooth design contacts perpendicular to the LED light-emitting area and with the LED light-emitting area, and described sawtooth is connected in sequence by a plurality of circular arc sawtooth unit.The diameter of each circular arc sawtooth unit is 0.13mm, is spaced apart 0.05mm between the adjacent sawtooth, i.e. straight section 0.05mm between 2 sawtooth.
Claims (2)
1. novel backlight source light guide plate broached-tooth design, be arranged on a side of light guide plate, it is characterized in that the sawtooth in this novel backlight source light guide plate broached-tooth design contacts perpendicular to the LED light-emitting area and with the LED light-emitting area, described sawtooth is connected in sequence by a plurality of circular arc sawtooth unit.
2. novel backlight according to claim 1 source light guide plate broached-tooth design is characterized in that the diameter of each circular arc sawtooth unit is 0.13mm, is spaced apart 0.05mm between the adjacent sawtooth.
