Abstract
The utility model discloses a sensor for detecting the variation of an incident angle of light in a single direction, which comprises a sensor box body (1), a light incidence hole (2) and light sensor elements (4). The light incidence hole (2) is arranged at the top of the sensor box body (1). Both sides of the position, which vertically corresponds to the light incidence hole (2), at the bottom of the sensor box body (1) are symmetrically provided with two light sensor elements (4). The sensor can only be used for sensing the variation condition of the light angle in the single direction, cannot be interfered by light in other directions and has the advantages that the sensor has simple structure, is convenient to use and has low cost.
Description
Technical field
The utility model relates to a kind of light sensor, and particularly a kind of angle of incidence of light degree that detects is at the sensor of folk prescription to variation.
Background technology
Along with development of science and technology; People have developed the equipment that utilizes solar electrical energy generation, and solar power plant is to rely on condenser mirror, with the sunshine reflect focalization to thermal-collecting tube; Through thermal-collecting tube sunshine is converted into heat absorption, and then heat energy is converted into electric energy.Imperative equipment is exactly a beam condensing unit in the solar electrical energy generation, because the sun is kept in motion, guarantee that beam condensing unit follows the tracks of the sun and can the maximize absorption incident light at any time, and light sensor is absolutely necessary so.The light sensor that is used on the beam condensing unit only need detect incident ray in unidirectional incident angle situation of change, and the traditional ray-casting sensor can receive the interference of other direction light when work.
The utility model content
The purpose of the utility model is, provides a kind of angle of incidence of light degree that detects at the sensor of folk prescription to variation, and it can only respond to the light angle situation of change on the single direction; Can not receive the interference of other direction light; Has advantage simple in structure, easy to use, with low cost.
The technical scheme of the utility model: a kind of angle of incidence of light degree that detects is at the sensor of folk prescription to variation; Comprise that sensor casing, light goes into perforation and light sensor element; Light is gone into the top that perforation is located at the sensor casing, and the bottom of sensor casing is gone into the vertical corresponding position symmetria bilateralis of perforation with light and is provided with two light sensor elements.
In the sensor that changes, go into perforation and be thin narrow slot by light at folk prescription for aforesaid detection angle of incidence of light degree.
In the sensor that changes, the inside of sensor casing is provided with light shield layer to aforesaid detection angle of incidence of light degree at folk prescription.The purpose that light shield layer is set is in order to guarantee that light sensor does not receive the interference of extraneous light.
Compared with prior art, the utility model makes sensor can only sense the light on the single direction owing to the light sensor element that is provided with two symmetrical distributions in the bottom of sensor casing, can not receive the interference of other direction light during work.Owing on the inwall of sensor casing, be provided with light shield layer, effectively guaranteed the operating accuracy of sensor.The utility model also has simple in structure, advantage of low manufacturing cost in addition.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Being labeled as in the accompanying drawing: 1-sensor casing, 2-light is gone into perforation, 3-light shield layer, 4-light sensor element.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
The embodiment of the utility model: as shown in Figure 1: a kind of angle of incidence of light degree that detects is at the sensor of folk prescription to variation; Comprise that sensor casing 1, light goes into perforation 2 and light sensor element 4; Light is gone into the top that perforation 2 is located at sensor casing 1, and the bottom of sensor casing 1 is gone into perforation 2 vertical corresponding position symmetria bilateralis with light and is provided with two light sensor elements 4.
Light is gone into perforation 2 and is thin narrow slot.The inside of sensor casing 1 is provided with light shield layer 3.
The principle of work of the utility model: under the normal condition; Light is vertically injected light and is gone into perforation 2, and when the light of monitoring on the direction just can shine on the light sensor element 4 during more than or equal to 0.1 ° with the vertical direction deflection angle, light sensor element 4 sends signals to control device; Control device control condenser support rotates; The light deflection angle will diminish after turning to respective angles, and when light deflection angle during less than 0.1 °, control device control condenser support stops operating.
Claims (3)
1. one kind is detected the angle of incidence of light degree at the sensor of folk prescription to variation; It is characterized in that: comprise that sensor casing (1), light goes into perforation (2) and light sensor element (4); Light is gone into the top that perforation (2) is located at sensor casing (1), and the bottom of sensor casing (1) is gone into the vertical corresponding position symmetria bilateralis of perforation (2) with light and is provided with two light sensor elements (4).
2. a kind of angle of incidence of light degree that detects according to claim 1 is characterized in that at the sensor of folk prescription to variation: light is gone into perforation (2) and is thin narrow slot.
