State reflecting part and the light that the LED sends is reflexed into the light out part.
It should be noted that realizing for LED 11 equably exporting to light out part using straight down type guide light mode
Surface when, it is necessary to ensure that position between LED 11 and light out part is set enough to remote, it is too near to avoid being designed to both
Shi Rongyi produces hot spot so as to cause light uneven.This feature of straight down type guide light mode causes that it compares in light-guide space
Good light guide effect cannot be obtained in small product, for this case, the present embodiment is being led using side entering type leaded light mode
Reflecting part and light out part are set in light part 20, LED are arranged on the reverse side of lamp plate 10, and light guide 10 is arranged on lamp plate
Reverse side, the light out part of light guide is set through lamp plate, and the light that LED is projected reflexes to light out part through the reflecting part of light guide, makes
Light out part reduces the volume of leaded light component to the Distance Shortened of lamp plate 10, by shading piece 30 by the anti-of the light guide 10
The portion of penetrating is covered, so that the light-output that is sent LED using the principle that light reflects of reflecting part is to light out part, it is ensured that certain
Guide-lighting distance, so as to ensure that light guide effect.
This implementation novel optic component is installed light guide 20 by the way that LED 11 to be arranged on the reverse side of lamp plate 10
In the reverse side of lamp plate 10, the light out part of light guide 20 is set through lamp plate 10 so that the Distance Shortened of light out part to lamp plate 10 and
The volume of leaded light component is reduced, the light that LED 11 is projected reflexes to light out part through the reflecting part of light guide 20, by by shading piece
30 reverse side for being arranged on the lamp plate 10 simultaneously cover the reflecting part, so that the reflecting part utilizes the principle that light reflects by LED
The light-output that lamp 11 sends is to light out part, it is ensured that certain guide-lighting distance, so as to ensure light guide effect.So, this practicality is new
Type realizes leaded light component in the smaller display device of light-guide space requirement, it is ensured that while light guide effect, reduce
The volume of leaded light component.
It is understood that the utility model leaded light component simple structure, small volume, it is easy to accomplish, the utility model
It is also applied in the small device of the light-guide space of other lightings requirement, this is not restricted.
Reference picture 1 and Fig. 2, in a preferred embodiment, the reflecting part has the light that the reception LED 11 sends
Incidence surface, the light injected through the incidence surface is reflexed to multiple reflectings surface of the light out part.
In the present embodiment, the light that the LED 11 sends is reflexed to next reflecting surface by multiple reflectings surface, to realize LED
Light along reflection route finally reflex to light out part.
Further, in above-described embodiment, the quantity of the reflecting surface is two, and the light sent along the LED 11
Line reflection to the path of the light out part is followed successively by the first reflecting surface and the second reflecting surface.
In the present embodiment, the light of LED 11 that the first reflecting surface is used to be injected through incidence surface reflexes to the second reflecting surface.The
Two reflectings surface are used to for the light that the first reflective surface comes to be radiated to light out part.
Further, the angle of the angle α between the light injected through the incidence surface and first reflecting surface is
45 °, through the angle of the angle β between the light and second reflecting surface of first reflective surface to second reflecting surface
Spend is 45 °.
In the present embodiment, the angle of the incident angle α between light that LED 11 sends and the first reflecting surface is 45 °, and first is anti-
The angle of the incident angle β penetrated between the light for reflecting in face and the second angle of reflection is 45 °.Certainly, it is incident in other implementations
The angle at angle can also be other values, and this is not restricted.
Further, first reflecting surface and second reflecting surface are smooth surface high.
In the present embodiment, the first reflecting surface and the second reflecting surface are preferably smooth surface high, are so more beneficial for the light of LED 11
Reflection, improves the reflectivity of the light of LED 11.Each transition location of the light of LED 11 in reflecting part can also be reduced simultaneously
Light loss.Certain first reflecting surface and the second reflecting surface can also be conducive to catoptric structure for minute surface etc..
Reference picture 1 and Fig. 2, in a preferred embodiment, the cylindrical setting of light out part, and top has exiting surface,
The exiting surface is cloudy surface structure.
In the present embodiment, the exiting surface of light out part preferably uses cloudy surface, because the surface of cloudy surface structure is coarse, more has
Beneficial to the unrestrained transmitting of light, when line is mapped to exiting surface, the light that exiting surface sends LED towards reflecting from all directions so that
Obtain the uniform light of the light of LED 11.
Reference picture 1 and Fig. 2, based on above-described embodiment, the reverse side of the lamp plate 10 is provided with multiple LEDs, described
The position of each LED of the correspondence of shading piece 30 is provided with the groove of the accommodating corresponding reflecting part.
In the present embodiment, LED is not limited for multiple, and quantity, and corresponding shading piece is provided with multiple accommodating light guides 20
The groove of reflecting part.
Further, the light guide 20 with the shading piece 30 respectively by such as leaded light such as transparent light guide powder, transparent resin
Material and such as aluminium, ink, resin light screening material are integrally formed making with dijection injection molding process.
In the present embodiment, using the technique of dijection injection moulding, light guide 20 and shading piece 30 are by optical material and shading
Material injection is integrally formed, so that reduce the volume of light guide 20 and shading piece 30, while being also prevented from letting out for light
Dew, shaded effect is more preferably.
Reference picture 1 and Fig. 2, in a preferred embodiment, the thickness h of the leaded light component is 4~5mm.
In the present embodiment, LED 11 is arranged on the reverse side of lamp plate 10, will by the reflecting part and light out part of light guide 20
The light-output of LED 11 is to the surface of leaded light component, while the technique that shading piece 30 and light guide 20 are used into dijection injection moulding
Injection is integral, and the light out part of light guide 20 is set through the lamp plate 10, so as to greatly shorten the volume of optical assembly, guide-lighting group
The thickness of part only 4~5mm just can be realized.
The utility model also proposes a kind of display device, the display device include leaded light component, the leaded light component it is specific
Structure employs whole technical schemes of above-mentioned all embodiments due to this leaded light component with reference to above-described embodiment, therefore at least
All beneficial effects that technical scheme with above-described embodiment is brought, this is no longer going to repeat them.Wherein, leaded light component bag
