Abstract
The utility model relates to a light post involving a light component for instrument and electric equipment. The light post is made of transparent material and provided with an external end arranged at the external surface of equipment and internal end close to optical and electric component; the external end is provided with a plurality of back taper cells arranged in an array. The utility model can effectively enhance optical detecting instrument's sensitivity to light signal of light instrument in inclined irradiation and lift the detection distance and angle. Observers may feel hard to see the shape of the light detector behind the light post. In the reverse application, when light of lighting part in the equipment is transmitted to any back taper cell of the external end through the internal end, part is reflected to the outside directly, and part is reflected to the outside one or a plurality of times after radiating to the neighboring bevel, thus dispersing the radiation angle of the light. The evenness of the light seen by external observers is remarkably improved, and it is difficult for them to see the shape of the lighting body behind the light column.
Description
Technical field
The utility model relates to the light-guide device of a kind of instrument, electric equipment use.
Technical background
For its inner photovalve can be played one's part to the full, usually the leaded light post of the light conducting of transparent material making to be installed in various instruments, the electric equipment at its outside surface.Modal leaded light post, inside and outside end face is the plane.Outside surface at some photovalve is cambered outwards arc, and for improving the efficient of leaded light, corresponding leaded light post inner face is the arc of indent, to increase the optically-coupled of leaded light post inner face and photovalve outside surface.For further improving the leaded light efficient of leaded light post, it is ZL 97237601.1 that China utility model patent instructions CN 2300113Y discloses the patent No., name is called the technical scheme of " a kind of leaded light post that improves remote-control sensitivity and increase remote control distance ", proposing the leaded light post is made of transparent cylinder, the inner face of the close infrared remote receiver of transparent cylinder is convex surface, make the infrared light that passes leaded light post directive infrared remote receiver converge at effectively being subjected in the optical range of infrared remote receiver, increase light income; Thereby improve remote-control sensitivity and increase remote control distance.But it also has following shortcoming: when light during from the oblique outer face that is radiated at the leaded light post, the incident light that can enter the leaded light post seldom, remote-control sensitivity and remote control distance all are subjected to very big influence and restriction.
The utility model content
The utility model aims to provide a kind of no matter light when forward still is the oblique outer face that is radiated at the leaded light post, can both have sufficient incident light to enter, thus the high leaded light post of leaded light efficient.
The technical solution of the utility model is: the leaded light post by the cylinder that transparent material is made, has the outer face that is installed in device outer surface and in abutting connection with the inner face of photovalve; Described outer face has a plurality of back taper nests that array-like is arranged.No matter light still is oblique any one back taper nest surface that is radiated at leaded light post outer face from forward, enters into the leaded light post through repeatedly reflecting, and the optically focused effect is arranged; Light behind the optically focused is transmitted to the light-detecting device outgoing in the inner equipment oriented, and the light quantity that light-detecting device records is strong during certainly than the situation that is directly incident on without optically focused in the leaded light post; Experimental results show that the utility model leaded light post is higher than correlation technique carries out optically focused to the direct incident ray that transmits in the leaded light post leaded light efficient to the extraneous light leaded light efficient that optically focused transmits then of going ahead of the rest in the leaded light post; When particularly light was from oblique each back taper nest that is radiated at leaded light post outer face, the light amount ratio light that passes to light-detecting device was strong during from the oblique situation that is radiated at correlation technique.
A kind of preferred constructive form of back taper nest is: described back taper nest is for just boring.
Another preferred constructive form of back taper nest is: described back taper nest is an inverted cone.
In a kind of preferred construction: described a plurality of back taper nests are arranged at grade and are big or small identical, so that mfg. moulding die, the method for cutting with line processes these back taper nests.
In a kind of preferred construction: the waist side between described outer face and the inner face is provided with the flange that extends laterally, so that location when installing.
Particularly: described flange is provided with the mounting hole that passes for the fixed installation part.So that install and fix.
In a kind of preferred construction: the waist side between described outer face and the inner face tilts to shrink towards inner face symmetrically.The side of tilt shrinking symmetrically is similar to the back taper nest for the light role of transmitting in the leaded light post, can increase the transmission efficiency of light between bigger outer face and less inner face.
In a kind of preferred construction: described inner face is the arc of indent, can enter photovalve to be fit to the cambered outwards arc-shaped outer surface of photovalve, to make as much as possible from the light of inner face outgoing, promptly improves the efficient of leaded light.
The utility model leaded light post, utilize the light gathering of back taper nest, a plurality of back taper nests of being arranged by array-like converge in the leaded light post light that shines the outer face, thereby improved the efficient of leaded light, sensitivity and the increase detection range and the angle of the light signal that sends in the time of can improving light-detecting device to the oblique irradiation of luminescent device significantly.Simultaneously, the observer is difficult to find out the shape of leaded light post back light-detecting device, realizes that manufacturer hides the hope of light-detecting device.The utility model leaded light post also can be used in the opposite application in addition, be positioned at light that the luminescent device of equipment sends when leaded light post inner face is transmitted to any one back taper nest surface, outer face, part light directly shines the outside, the light that a part shines adjacent chamfered portion reflexes to the outside through one or many again, dispersed the angle of radiation of emergent light, the luminous uniformity coefficient that the external observer is seen is significantly improved, and also is difficult to find out the luminophor shape of leaded light post back.Thus, the purposes of the utility model leaded light post is more extensive.
