The invention discloses an image detection-based on-line detection and correction method of a reflection angle of a heliostat. Firstly, the heliostat to be corrected and a solar facula image in the heliostat are shot through a camera, the obtained image is processed, whether the solar facula image is positioned in the central position of the heliostat or not is judged, and if the solar facula image is positioned in the central position of the heliostat, the camera is aligned with the heliostat to be corrected; otherwise, the reflection angle deviation Theta of the heliostat is calculated according to the offset of the solar facula image from the central position of the heliostat, and a normal direction of the heliostat is controlled to rotate towards a direction in which the deviation is eliminated at an angle of half the Theta; and secondly, a declination angle Theta' between an angle for the camera to be aligned with the heliostat and an angle for the heliostat to be aligned with a heat collector is calculated, and the heliostat already aligned with the camera is rotated towards the heat collector for half the Theta'. By adopting the method, the heliostat can be accurately aligned with the heat collector when a static field is mounted, and errors caused by mechanical deformation and foundation settlement during long-term running of the static field can be corrected.

The invention relates to a condenser lens and a lamp using the same. The condenser lens is truncated cone-shaped and is symmetric relative to the lens axis. The condenser lens is characterized in that the middle of a first end surface with smaller diameter sinks inwards to form a light source accommodating cavity for adaptively accommodating the LED light source and the bottom surface of the light source accommodating cavity protrudes outwards to form a convex sphere; a second end surface with larger diameter is a plane; and a side wall of the condenser lens is a fully reflecting surface, thegeneratrix of the truncated cone-shaped lens is a fold line and is formed by connecting multiple line segments in sequence, and the multiple line segments and the lens axis form an angle shown in thespecification, wherein n is the index of refraction in condenser lens.
