Example Embodiment

[0020] The light tracking sensor of the present invention is suitable for a trough-type reflecting mirror concentrating solar heating system, also can be applied to a dish-type reflecting medium-high temperature concentrating solar energy system, and can also be applied to a solar photovoltaic power generation system. The optical tracking sensor provided according to the present invention, as shown in the figure, includes two or more optical gap devices with a certain length, and one end of each optical gap device is a common single-point micro-hole. The hole is used as the input port 1 of the directional light, and the other end of each optical gap device is the light outlet 2 of the directional light. The light outlet 2 is respectively provided with a photosensitive element, such as a photodiode.

Abstract

Disclosed is a light tracing sensor which comprises two or more light intervals with certain length, wherein one end of each light intervals is one common single-point micro-hole for input port of direction light; the other end of each light interval is one light output port equipped with a light sensing component. The invention is characterized in that one end of each light interval device is a common single-point micro-hole, and around the micro-hole is raised curve surface; and the invention has a sphere shape top water-falling structure. The invention has the advantages that the light tracing sensor is simpler than prior invention; the faller leaves rain can not fall into the single-point micro-hole easily which makes the sensor has higher sensing precision of direction light.
