Abstract
The utility model discloses a kind of ultrathin charactron, including plastic housing, pcb board and LED lamp, light guide plate is provided in the plastic housing, the LED lamp is located at light guide plate one side, and the LED lamp is side-emitting led wick and light emission direction towards light guide plate.The utility model is compared with prior art, utilize the guide-lighting function of the refraction of light guide plate, by LED lamp selected as side illumination mode, the light that LED lamp is sent is entered in light guide plate, what can be uniformly dispersed under the action of light guide plate lights the entire window of plastic housing, so as to eliminate limitation of the plastic housing thickness for light emitting region, the technical bottleneck of superthin structure can not be made by breaching existing charactron, not only product thickness is significantly thinned, and using the effective range of exposures bigger of cooperation of light guide plate and single wick, more save cost, Product Windows shine evenly, effect is more preferable.
Description
Technical field
The utility model belongs to charactron technical field, and in particular to a kind of ultrathin type charactron.
Background technology
The composition of existing charactron is as depicted in figs. 1 and 2, installs LED lamp 3 luminous upwards on pcb board 2, so
The pcb board for being mounted with the LED lamp to shine upwards 3 is encapsulated into plastic housing 1 afterwards, have in plastic housing 1 different size of digital 8 word and
Window, LED lamp 3, which is powered, lights rear 8 word of number and window that just can be shown with size, LED lamp 3 arrive 1 surface of plastic housing away from
From for emitting cavity height, LED lamp 3 shines for front, and light emitting angle is generally 90 degree, and emitting cavity height is higher, can irradiate
Area is bigger, the same flashlight of principle, so some large-sized windows need emitting cavity doing height or increase LED lamp
Quantity to reach luminous uniform effect, but the problem of can so cause product thickness excessive and brings cost increase.
Cause some product structures limitation require the charactron of very thin thickness that can not realize, if charactron do it is too thin,
During the insufficient height of emitting cavity, the light emitting angle of LED chip can not cover entire display area, can cause point light source, influence to show
Show effect, even if increasing chip can not thoroughly solve the problems, such as.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, provide it is a kind of coordinate in a manner that side shines lead
The use of tabula rasa can realize the ultrathin charactron of charactron thickness ultrathin.
Technical solution：To achieve the above object, the utility model provides a kind of ultrathin charactron, including plastic housing, pcb board
And LED lamp, light guide plate is provided in the plastic housing, the LED lamp is located at light guide plate one side, and the LED lamp is side
Light-emitting LED wick and light emission direction are towards light guide plate.
The design principle of the utility model is：Using the guide-lighting function of the refraction of light guide plate, LED lamp selected as side is sent out
Light mode, the light that LED lamp is sent are entered in light guide plate, and what can be uniformly dispersed under the action of light guide plate lights plastic housing
Entire window, so as to eliminate limitation of the plastic housing thickness for light emitting region.
Further, the LED lamp fits with light guide plate, so can be ensured that the light that LED lamp is sent from side
Line is all introduced into light guide plate, avoids the situation for light leak occur.
Further, the LED lamp is partially embedded into light guide plate, so improves light guide plate and LED lamp is mutual
Between positional stability.
Further, the light guide plate is located at the center in plastic housing.
Further, the plastic housing surface is provided with pad pasting.
Further, the thickness of the plastic housing is equal to the thickness of light guide plate.
Advantageous effect：The utility model reflects guide-lighting function compared with prior art, using light guide plate, by LED light
Core selected as side illumination mode, the light that LED lamp is sent are entered in light guide plate, can uniformly divided under the action of light guide plate
The scattered entire window for lighting plastic housing, so as to eliminate limitation of the plastic housing thickness for light emitting region, breaches existing number
Pipe can not make the technical bottleneck of superthin structure, and not only product thickness is significantly thinned, and use light guide plate and single wick
The effective range of exposures bigger of cooperation, more save cost, Product Windows shine evenly, and effect is more preferable.

Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology
Personnel fall within the application scope as defined in the appended claims to the modification of the various equivalent forms of the utility model.
Embodiment 1：
As shown in Figure 3 and Figure 4, the utility model provides a kind of ultrathin charactron, including plastic housing 1, pcb board 2 and LED light
Core 4 is provided with light guide plate 5 in the plastic housing 1, and the LED lamp 4 is located at 5 one side of light guide plate, and the LED lamp 4 is side hair
Light LED lamp and light emission direction is towards light guide plate 5, the LED lamp 4 fits with light guide plate 5, and the light guide plate 5 is located at modeling
Center in shell 1,1 surface of plastic housing are provided with pad pasting 6.
Embodiment 2：
As shown in Figure 3 and Figure 4, the LED lamp 4 of lateral emitting is fixed on pcb board 2, the thickness of the pcb board 2 is
After plastic housing 1 and pcb board 2 rivet together, light guide plate 5, light guide plate 5 and LED light are embedded in 1 corresponding window of plastic housing by 1cm
Core 4 fits, and the thickness of the plastic housing 1 is 1cm, and the pad pasting 6 of the good content of silk-screen, the patch are then sticked on the surface of plastic housing 1
The thickness of film 6 is 0.2cm, its integral thickness is 2.2cm after the completion of such charactron assembling, and traditional charactron integral thickness
Generally all in more than 6cm, the thickness of charactron, which realizes, to decline to a great extent.
