Description

A kind of set-top box orienting holder with LED light

Technical field

The utility model is related to set-top box technique field more particularly to a kind of set-top boxes orienting holder with LED light.

Background technology

As technology develops, the function of DTV STB is further perfect, increases with the function of set-top box, It is consequently increased on set-top box for embodying the indicator lamp quantity of corresponding function state, is exactly set-top box interior circuit board in practice On the LED light arranged it is more and more, its internal LED light of general set-top box is directly plugged in after being connected with circuit board In indicator light inserting groove on shell, therefore, often occurring also can be straight from the heat emission hole of set-top box shell surrounding and fit-up gap It connects and sees luminous point, cause set-top box shell light leakage than more serious.And often by the instruction with different definition in set-top box The color setting of lamp differs, therefore also often occurs having seriously affected user's there is a phenomenon where mutual crosstalk between LED light It uses.

In the prior art generally above-mentioned string is solved by the way of reducing the apparent heat emission hole of shell or fit-up gap It disturbs and leakage problem, and this can also increase the difficulty realized on set up box structure and limit to a certain extent to a certain extent Set-top box apparent layout.

Utility model content

Place in view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of band LED light orientation branch The set-top box of frame can make LED light by assigned direction scattering light, avoid the crosstalk of light between LED light, while can also improve The leakage problem of set-top box heat emission hole and fit-up gap in appearance.

The purpose of this utility model is achieved through the following technical solutions：

A kind of set-top box orienting holder with LED light, including the upper shell and lower housing that are detachably connected, the lower housing Circuit board is inside installed, multiple LED light are installed on the circuit board, and is also equipped with orientation holder on circuit boards, it is described It includes multiple orientation lampshades to orient holder, and the quantity for orienting lampshade is identical as LED light quantity, and the orientation lampshade is equipped with perpendicular Straight perforative through-hole；It is connected with several light-guiding pillars corresponding with orientation lampshade on the upper shell, and is opened on upper shell Equipped with several light-conductive holes corresponding with light-guiding pillar, one end of the orientation lampshade fits in circuit board surface and by LED light circle In through-hole, the other end for orienting lampshade fits in the end of light-guiding pillar；

In the set up box structure for orienting holder with LED light of the utility model, by orienting the oriented lamp on holder In its center by LED light frame, then its surrounding of LED light scatters light is directed lampshade and intercepts barrier cover, orients on lampshade Upward notch is only remained, the light that LED light scatters is transmitted to shell under the limit conduction of orientation lampshade through light-guiding pillar External surface, and the light of the dissipated hair of different LED light constrains it due to being directed lampshade and can only upwardly propagate, it can be effective The phase is avoided to be irradiated to adjacent light-guiding pillar end face and crosstalk occurs, while from the heat emission hole of set-top box shell surrounding and fit-up gap It can not be immediately seen luminous point, to solve set-top box leakage problem.

Further, the orientation holder and circuit board are clamping, and orientation holder is equipped with buckle, opens up on circuit boards Have and buckle matched mounting hole with described, other connection types, such as welding or grafting can also be used in practice.

Further, the face shaping of the orientation lampshade is wide at the top and narrow at the bottom tubaeform, wide using the narrow top in lower part It is tubaeform, by LED light frame in the relatively narrow space in lower part, it may make orientation lampshade to the peripheral frame barriering effect of LED light light more It is good, and the wider top of lampshade will be oriented and fitted with light-guiding pillar, conduction of the light-guiding pillar to LED light light can be more advantageous to.

Further, it is laid with heat emission hole in the front of the lower housing and/or side, it in practice can also be according to specific need It asks and opens up corresponding heat emission hole at positions such as the upper surfaces of upper shell.

Further, it is covered with light-transmissive film piece on the light-conductive hole of the upper shell, which preferably uses all-transparent Or translucent optical material makes.

The utility model compared with the prior art, has the following advantages and advantageous effect：

By the set-top box for orienting holder with LED light of the utility model, can be realized by the orientation holder in set-top box It allows the light that LED light is sent out to be scattered by assigned direction, the phenomenon that avoid the occurrence of mutual crosstalk between LED light and solves set-top box The problem of light leakage, meanwhile, the utility model orients the set-top box of holder also with simple in structure, easy for installation, suitable with LED light With the wide feature of range.
