Description
Technical field
The utility model relates to guiding device field, particularly, relates to a kind of light guide column structure.
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 installing 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 installing 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 light guide column structure, 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 light guide column structure, comprise the first guide-lighting block and the second guide-lighting block perpendicular with the first guide-lighting block, described first guide-lighting block is the square column that cross section is identical with the second guide-lighting block, light reflection block is connected with between described first guide-lighting block and the second guide-lighting block, described first guide-lighting block, second guide-lighting block and light reflection block are structure as a whole, described light reflection block becomes the circular arc of quadrant and cross section is identical with the cross section of the first guide-lighting block, the internal diameter of described light reflection block is more than or equal to 2 times of the first guide-lighting block diameter, one end of described first guide-lighting block or the second guide-lighting block is provided with installing hole.
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 square column with the second guide-lighting block and mutually vertical, 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.Utilize installing hole to carry out installation to lED lamp to fix, make to be close between lED lamp and light-guiding pillar, the air reduced between lED lamp and light-guiding pillar reduces, and namely reduces Fresnel loss, improves the capture rate of light, can reach 93%.First guide-lighting block, the second guide-lighting block and light reflection block are structure as a whole, and reduce the loss of light.Because light reflection block is arc-shaped, therefore namely the cross section of light reflection block refers to tangent plane diametrically, therefore the distance in internal diameter and medial surface and the center of circle.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%.
As preferably, the internal diameter of described light reflection block equals 2 times of the first guide-lighting block diameter.
As preferably, described mounting hole site is in the center of the first guide-lighting block or the second guide-lighting block end face.
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, installing hole.
