Abstract
The invention discloses a reflector for an HID vacuum sealed type elliptic type grading lighting lamp, in particular to an integral-diffuse-reflection elliptic curve hook surface combined profile reflector made of high borosilicate glass materials. The reflecting face is a combined profile with the elliptic curve hook surface as the benchmark and is obtained in the manner that reflection design is carried out on the whole reflecting face from a mouth part to the center of the bottom on the benchmark of the reflecting face. The mouth part of the elliptic curve hook surface benchmark is an ellipse shown in the formula: x<2>/a<2>+y<2>/b<2>=1, the hook surface of the elliptic curve hook surface benchmark is parallel to the yoz coordinate surface with the ellipse shown in the formula: y<2>/b<2>+z<2>/c<2>=1, wherein the focal length of the ellipse is a fixed value, the ellipse moves in the positive and negative direction of the axis x and is crossed with the ellipse shown in the formula: x<2>/a<2>+y<2>/b<2>=1 in the xoy coordinate surface, and a hook face formed by infinite continuous semi ellipses is obtained. The integral diffuse reflection design is the diffuse reflection design that the elliptic curve hook surface serves as the benchmark, and a plurality of circumferential sealed type arc annular grooves are designed in the whole reflecting face from the mouth part to the bottom on the benchmark of the elliptic curve hook surface. By means of the reflector, the effects of even grading, high efficiency and energy saving can be achieved.
