Abstract

The utility model provides a light guide column, which comprises a block body and a column body, wherein the block body is arranged on a circuit board in an electronic device; the circuit board is provided with a light-emitting assembly which is covered in the block body; one end of the column body is inserted into the block body, and the other end is extended to the outside of a casing arranged by the electronic device. When the light-emitting assembly sends out light sources, the block body can obstruct the diffusion and the penetration of the light sources sent by the light-emitting assembly, and the light sources are endlessly reflected in the column body. Thus, the light sources are guided to the outside of the casing of the electronic device.

Description

The leaded light post

Technical field

The utility model provides a kind of leaded light post, especially refer to a kind of being installed in the electronic installation, by block and cylinder composition with blocking-up and prevent light source scattering that luminescence component is sent or excessive optical phenomenon, and clearly this light source be passed to this electronic installation leaded light rod structure in addition.

Background technology

Generally speaking, (Light Emitting Diode is called for short: be with III-V or II-VI compound semiconductor (GaAs, GaP LED) light emitting diode, AlxGal-xAs, ZnSe ...) the P/N diode with lighting function (Light Emitting) made for material.Its luminous principle is under bias voltage forward, the N type is combined with the electronics of P-type semiconductor, electric hole, because of electronic switch can produce superfluous energy in rank, and disengage photon and luminous, electric current through power supply constantly replenishes electronics and electric hole to N type and P-type semiconductor, make electronics, electric hole in conjunction with and luminous continuing carries out, and make LED constantly luminous.Hence one can see that, LED is different from the conventional incandescent bulb by the luminous principle of heat energy by the principle of electronic energy rank conversion luminescence, so LED is a kind of cold light luminescence component, compared to by the luminous incandescent lamp bulb of heat energy, the advantage of LED has: caloric value is few, the life-span is long, power consumption is few, monochromatic light is luminous, reaction speed is fast, anti-collision, against weather is good, volume is little, easy miniaturization and or the like.

In the field of visible light, in initial stage and main at present the application, LED cuts each application market (as the indicator lamp of household appliances, information products, communication product, backlight or the like) to replace miniature incandescent lamp, high brightness product development is afterwards finished and commercialization, more enlarged its application, as automobile the 3rd brake lamp, large-scale billboards or the like, high brightness InGaN material series Products Development in recent years, facilitated the realization of high-brightness white-light LED, in a foreseeable future, LED will be applied in lighting field, be regarded as the great revolution of illumination market.

And LED is on the purposes as the indication of above-mentioned each equipment, normally be installed on the circuit board of each equipment, then be provided with the leaded light post between each apparatus casing surface and LED, this leaded light post of prior art is provided with pedestal, this pedestal is provided with at least one outward extending leaded light post, these leaded light post one ends are connected with LED, end then is connected on the panel of electronic installation in addition, the light source that makes these LED send can be shown on this panel via the guiding of these leaded light posts, again, this pedestal one side stretches out and is provided with the first chimeric assembly, another side then stretches out and is provided with the second chimeric assembly that matches with this first chimeric assembly, its by the first chimeric component chimeric of pedestal on the second chimeric assembly of another pedestal, this two pedestal is connected together, so, the user can optionally show the quantity of the light source of LED, and the leaded light post of equal amount is connected together by its pedestal.

But; no matter this leaded light post is single direction or the multidirectional light source that projects; if the user watches this leaded light post from different angle positions; the light source that this leaded light post is projected; there are brightness irregularities or excessive optical phenomenon in the capital, causes inconvenience and puzzlement in the use, in addition; because message has many kinds; Chang Wufa expresses clearly with a kind of LED of color, often need represent by the LED of multiple color, but because of the hypotelorism of LED; regular meeting interferes with each other light source; when two or more colors mix, or two or more color promptly can show unclear when showing simultaneously; the erroneous judgement that often causes the user that message is shown; the improvement mode of prior art is to adopt the shading rib to intercept the transmission of light source, and its improved effect is also not obvious, also has the spacing with LED to strengthen; to prevent the transmission of light source; but this kind mode needs the cooperation of circuit board and outward appearance, and crosses when bright when led light source, still still produces the phenomenon of printing opacity; therefore, above-mentioned member and mode of ameliorating can't thoroughly solve problems such as interference and printing opacity all the time.

Summary of the invention

Therefore, the utility model designer creates the utility model in view of the foregoing.

The purpose of this utility model is to provide a kind of leaded light post, and this leaded light post can solve that light source that prior art exists disturbs and problem such as printing opacity.

The utility model provides a kind of leaded light post, and it is located on the interior circuit board of electronic installation, makes the light source that luminescence component sent on this circuit board, can be directed to outside this electronic installation via this leaded light post, to demonstrate this light source, it is characterized in that this leaded light post comprises:

Block, it is light tight structure and is located on this circuit board that this block can cover the luminescence component on this circuit board;

Cylinder, it is plugged on this block, and an end of this cylinder inserts in this block, and the other end extends to outside the set housing of this electronic installation.

This above-mentioned block of the utility model can intercept the light source diffusion that this luminescence component sends or penetrate the interference that is caused, and makes this light source be subjected to the guiding of this cylinder, can clearly this light source be presented at outside the housing of this electronic installation.

Above-mentioned block comprises: groove, and it is located on the bottom surface of this block, just can hold the luminescence component on this circuit board in this groove, and the space is arranged at the bottom of the end face of this luminescence component and this groove; Spliced eye, an end of this spliced eye is opened in the position of this bottom portion of groove corresponding to this luminescence component, and the other end is opened on the end face of this block, and this spliced eye can be pegged graft for an end of this cylinder.

Above-mentioned cylinder comprises: the Plug Division, and it is located at an end of this cylinder, and is plugged in this block, and this Plug Division has the space less than this cylinder between the end face of this Plug Division and this luminescence component; Visible area, it is located at the other end of this cylinder, and this visible area extends to outside the hole that this housing offers.

The utility model leaded light post, its visible area preferably is the cloudy surface shape, more preferably is the texture shape.

The leaded light post of the utility model design can simple and easyly effectively prevent the light source transmission, can clearly this light source be directed to outside this electronic installation the phenomenon of having avoided existing light source to disturb again.
