Abstract
The utility model provides a kind of light guide ring by side direction light, pcb board including being provided with electroluminescent lamp, the pcb board is provided with upper lid, there is the light guide ring of energy printing opacity in the middle part of the upper lid, the electroluminescent lamp is distributed in light guide ring lower end the week side of boss, the light guide ring lower end has the conical surface from top to bottom gradually narrowed, the conical surface is towards electroluminescent lamp, the light of the week side of boss is imported into light guide ring entirety using the gradient of the conical surface, so by the light that reflects than light to be arranged on to the light beam of light guide ring bottom direct projection come evenly soft, it is to avoid the uneven situation of dazzling and light and shade occur.
Description
Technical field
The utility model is related to a kind of light guide ring by side direction light.
Background technology
The button of existing electronic device is luminous generally in button bottom setting light-emitting component, or in button week in order to realize
Portion sets the light guide ring of transparent material so that the light guide of the light-emitting component of bottom is passed through into case surface, yet with what is be introduced directly into
Light-emitting component, which is typically directly transmitted, to be easily caused dazzling and light guide ring luminous place and is also centrally located at the position for being placed with light-emitting component
Put.
The content of the invention
The utility model is improved above mentioned problem, i.e., the technical problems to be solved in the utility model is existing electricity
Sub- device is luminous to be easily caused dazzling and skewness.
Specific embodiment of the present utility model is：A kind of light guide ring by side direction light, including it is provided with electroluminescent lamp
Pcb board, the pcb board is provided with the light guide ring for having energy printing opacity in the middle part of upper lid, the upper lid, and the electroluminescent lamp is distributed in leaded light
Ring lower end the week side of boss, the light guide ring lower end has from top to bottom a gradually narrowed conical surface, and the conical surface is towards electroluminescent lamp.
Further, it is provided with to have in the middle part of button, the upper lid in the middle part of the light guide ring and extends internally for inserting leaded light
The conduit of ring, the guide-lighting surrounding place side is provided with annular protrusion, and the upper edge of the annular protrusion coordinates to realize limit with conduit lower edge
The spacing panel of extension in the middle part of position, light guide ring, spacing panel is provided with slot, and the button lower end, which has, can buckle into the card of slot
Button.
Further, the electroluminescent lamp is LED.
Further, the guide-lighting ring material is glass or lucite.
Compared with prior art, the utility model has the advantages that：The utility model utilization conical surface simple in construction
Gradient the light of the week side of boss imports to light guide ring is overall, it is straight that light is arranged on into light guide ring bottom so by the light ratio that reflects
The light beam penetrated comes evenly soft, it is to avoid the uneven situation of dazzling and light and shade occur.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cross-sectional view.
Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1~2, a kind of light guide ring by side direction light, including it is provided with the pcb board 10 of electroluminescent lamp 110, institute
Pcb board 10 is stated provided with upper lid 20, there is the light guide ring 30 of energy printing opacity at the upper middle part of lid 20, the middle part of light guide ring 30, which is provided with, presses
Key 40, the electroluminescent lamp 110 is distributed in the lower end the week side of boss of light guide ring 30, and the lower end of light guide ring 30, which has, from top to bottom gradually narrows
The conical surface 310, the conical surface 310 is towards electroluminescent lamp.
In the present embodiment, as shown in Fig. 2 the electroluminescent lamp 110 is LED, the material of light guide ring 30 is glass or had
The light transmissive material that machine glass is made, because the light that it sends relative to electroluminescent lamp 110 of the conical surface 310 of light guide ring 30 is by the conical surface
Gradient is refracted into light guide ring 30 and inputted to top, shown in light path along arrow mark, due to employing refraction in the present embodiment
Light avoid perspective light it is dazzling, be also light guide ring 30 light be more uniformly distributed it is soft.
LED etc. power supply can be provided by the built-in power on pcb board in the present embodiment, can also be by being carried outside upper lid 20
Via line is supplied.
In order to realize the fixation to button 40 in the present embodiment, the upper middle part of lid 20 has to extend internally leads for inserting
The conduit 120 of the ring of light, the guide-lighting surrounding place side be provided with annular protrusion 320, the upper edge of the annular protrusion 320 with conduit 120
Spacing to realize along coordinating, the spacing panel 330 of extension in the middle part of light guide ring, spacing panel 330 is provided with slot 331, the button
Lower end, which has, can buckle into the buckle 410 of slot 331.In actual design, button 40 can be designed to as needed knob driving or
It is pressing driving.
The either component that the utility model is provided can be assembled by multiple single parts, or
The separate part that integrally formed technique is manufactured.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Still embodiment of the present utility model can be modified or some technical characteristics are equally replaced
Change；Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
Among scope.
