Description
Technical field
The utility model relates to guiding device field, particularly, relates to a kind of low-loss light-guiding pillar.
Background technology
In a lot of electric equipment, all need to use the state of LED to equipment and show, so that carry out control operation to equipment.LED need be arranged on the shell of equipment, is just easy to people's observation.Due to LED welding position or other factors, LED has a segment distance apart from the mounting hole of LED on device housings, is not easy to the observation of people.In order to better, the light of LED is drawn, generally adopt light-guiding pillar.Light-guiding pillar be exactly by light with minimum loss from a light sources transmit to apart from this light source certain distance another point device.Utilize light-guiding pillar LED lamplight to be drawn, existing light-guiding pillar is mostly straight tube or polygon prism, when the mounting means of LED changeable or perpendicular with mounting hole time, existing light-guiding pillar is obviously not too suitable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of low-loss light-guiding pillar, and LED lamplight bending can be derived by it, and the high and low loss of guide-lighting efficiency, meet the multiple mounting modes of LED.
The technical scheme in the invention for solving the above technical problem is:
A kind of low-loss light-guiding pillar, comprise the first guide-lighting block and the second guide-lighting block, described first guide-lighting block and the second guide-lighting block perpendicular, described first guide-lighting block and the second guide-lighting block are isodiametric cylinder, light reflection block is connected with between described first guide-lighting block and the second guide-lighting block, described light reflection block is the cylinder of quadrant, the internal diameter of described light reflection block is more than or equal to 2 times of the first guide-lighting block diameter, and the described first guide-lighting block, the second guide-lighting block and light reflection block are structure as a whole.
Because the first guide-lighting block and the second guide-lighting block are cylinder, therefore the first guide-lighting block and the second guide-lighting block is perpendicular refers to its axis perpendicular.The utility model improves on existing light-guiding pillar, is set to by light-guiding pillar to bend, LED lamplight bending is derived, be applicable to the multiple mounting modes of LED.First guide-lighting block is mutually vertical with the second guide-lighting block, and junction utilizes light reflection block effectively to reflect derivation to light.First guide-lighting block is mutually vertical with the second guide-lighting block, as shown in Figure 1, LED lamplight derives through the second guide-lighting block after the first guide-lighting block conduction, the reflection of light reflection block, LED lamplight is block guide-lighting with first and the parallel conduction of the second guide-lighting block in conductive process, every bar light that LED lamplight penetrates in the first guide-lighting block all can effectively spread out of, the effective loss reducing light.Experimental study and theoretical proof, when the internal diameter of light reflection block is more than or equal to 2 times of the first guide-lighting block diameter, effectively can reduce the loss of light, its loss rate can be reduced to 5%.First guide-lighting block, the second guide-lighting block and light reflection block are structure as a whole, and avoid light to be repeatedly coupled in conductive process, reduce the loss of light.
As preferably, the internal diameter of described light reflection block equals 2 times of the first guide-lighting block diameter.
As preferably, in order to be suitable for the installation of similar conical LED, and improve the brightness of light conduction, one end of the described first guide-lighting block or the second guide-lighting block is provided with mounting hole, and one end of the described second guide-lighting block or the first guide-lighting block flushes with the axis of the first guide-lighting block or the second guide-lighting block.Mounting hole is used for mounted LED lamp, effectively can reduce the loss that light is caught by light-guiding pillar.
Further, described mounting hole is coaxial with the first guide-lighting block, and namely mounting hole is arranged on the center of the first guide-lighting block.
Further, the aperture of described mounting hole is less than 1/3rd of the first guide-lighting block diameter.
To sum up, the beneficial effects of the utility model are:
1, the first guide-lighting block of the present utility model is mutually vertical with the second guide-lighting block, and junction utilizes light reflection block effectively to reflect derivation to light, is applicable to the multiple mounting modes of LED.
2, the internal diameter of light reflection block of the present utility model is more than or equal to 2 times of the first guide-lighting block diameter, effectively can reduce the loss of light, and its loss rate can be reduced to 5%, strengthens the light luminance that people sees.
3, structure of the present utility model is simple, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding parts title in accompanying drawing: 1, the first guide-lighting block; 2, the second guide-lighting block; 3, light reflection block; 4, mounting hole.
