Abstract
The utility model relates to an LED edge backlight module structure, which comprises a lamp panel (21), an LED (22), a light guide plate (23) and reflectors (24); the mounting contact surface of the light guide plate (23) and the LED (22) is stepped, and the step is meshed and fitted with a step formed by the lamp panel (21) and the LED (22); and the periphery of the LED edge backlight module structure, except a lamp panel mounting surface and a light guide plate luminous surface (231), is enclosed by the reflectors (24). In the LED edge backlight module structure, because the emergent surface of the LED (22) is vertical to the lamp panel (21), light enters the light guide plate (23) from a protrusion part of the light guide plate (23) on the side of the light guide plate (23), is totally reflected inside the light guide plate (23), and is finally emitted from the emergent surface of the light guide plate (23) through the refraction of printing dots or microstructures on the bottom surface of the light guide plate (23). Therefore, the thickness of the light guide plate (23) can be reduced to make a flat-panel television thinner and not to influence the display effect of the television.
Description
Technical field
The utility model relates to a kind of LED side module backlight, more particularly, relates to a kind of LED side back light module unit structure of dull and stereotyped liquid crystal TV set.
Background technology
Along with development of science and technology, lcd technology is more and more ripe, and TV is also from traditional kinescope liquid crystal display till now.LCDs is passive luminous display screen, liquid crystal itself is not luminous, so LCDs needs module backlight that light source is provided, divide from the classification of light source, can be divided into CCFL (ColdCathode Fluorescent Lamps, cold-cathode fluorescence lamp) module backlight, LED (Light EmittingDiode, light emitting diode) module backlight etc.
The LED-backlit module divides according to the LED position can be divided into direct-light type LED backlight module and LED side module backlight.But it is thin a lot of that the thickness of LED side module backlight can be done than straight-down negative, also can save partial L ED lamp simultaneously do not influence uniformity.
At present general LED side back light module unit structure as shown in Figure 1.LED12 is installed on the lamp plate 11, the incidence surface of LGP 13 and the light-emitting area of LED12 are fitted, the light-emitting area of LED12 is vertical with the exiting surface of LGP 13, and the periphery of whole LED side back light module unit structure all surrounds with reflector plate 14 except the installed surface of the exiting surface of LGP 13 and lamp plate 11.LGP 13 all is the design of rectangle generally, the light that LED12 sends is injected from the incidence surface of LGP 13, and total reflection takes place in LGP 13, LGP 13 bottoms have from close to sources to the distance light source, from small to large, from dredging to close site or micro-structural, so the site of LGP 13 or micro-structural figure more complicated and related with the utility model little are not expression among the figure.Last light penetrates from LGP 13 exiting surfaces, becomes area source.
In general in the LED side module backlight, the using method of LED is generally a plurality of LED and is mounted on the LED lamp bar.LGP accounts for a very consequence in LED side module backlight, because side core backlight is exactly to rely on LGP that the light of LED lamp is changed into area source from spot light.The slimming of flat panel TV requires more and more higher, and the thickness of LGP also reduces gradually.But the Thickness Design of LGP is more little, and the exiting surface of LED lamp and the incidence surface of LGP are also more little, and the utilization rate of light can reduce, and this has just influenced the actual displayed effect of TV.
The utility model content
The technical problems to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of and can satisfy the LED side back light module unit structure that reduces light guide plate and do not influence the utilization rate of light simultaneously.
LED side provided by the utility model module backlight, described LED side module backlight comprises lamp plate, LED, LGP and reflector plate, LED is installed on the lamp plate, the lamp plate that posts the LED lamp, the stepped design of installation contact-making surface of described LGP and LED lamp plate are installed around the exiting surface of LGP.
LED side provided by the utility model module backlight, the mutual interlock of ladder that the stairstepping of the installation contact-making surface of described LGP and LED lamp plate and lamp plate and LED form coincide.
LED side provided by the utility model module backlight, described side-emitting LED lamp, the light-emitting area of LED is vertical with lamp plate.
LED side provided by the utility model module backlight, the light-emitting area of described LED is parallel with the exiting surface of LGP.
LED side provided by the utility model module backlight, described lamp plate are the pcb of metal base or the pcb plate of non-metallic substrate.
LED side provided by the utility model module backlight, described lamp plate is aluminium base pcb.
LED side provided by the utility model module backlight, described LED is at least single sided lamp.
Implement LED side back light module unit structure of the present utility model, have following beneficial effect: because the side-emitting LED lamp that the utility model uses adopts light-emitting area perpendicular to LED lamp and lamp plate installed surface, and the LGP that formed ladder is complementary after employing and LED and the lamp plate installation carries out the design of LED side module backlight.By the step trough of LGP, match with the side-emitting LED lamp, the light of side-emitting LED lamp is injected LGP, takes place to penetrate from exiting surface after total reflection and the refraction in LGP.Equidistant encapsulation is used because the feature of LED is a plurality of LED, be shaped as flat cuboid, the organization plan that the utility model adopted can make LED side module backlight when reducing light guide plate, does not reduce the light inlet area of LGP, can obtain higher light utilization efficiency.Whereby can LED side module backlight do thinner than traditional ultra-thin LED side module backlight, thereby the thickness of realizing dull and stereotyped LCD TV becomes thinner and does not influence display effect.
