    • PURPOSE: A retrofit LED lamp, a manufacturing method thereof, and a retrofeet multi LED lamp structure thereof are provided to improve directivity and the range of illumination by using an optical convex lens. CONSTITUTION: A plurality of heat radiation fins are formed in the outer peripheral surface of a heat-sink(10). A convex lens(30) is made of a transparent acrylic material. The convex lens is installed inside the fitting end of the heat-sink. A gasket ring(20) is made of a silicon rubber material. The gasket ring is inserted between the hitch bed of the fitting end of the heat-sink and the protrusion end of the convex lens. A plurality of LED modules are installed on a PCB(40). A shaft(50) includes a first cylindrical body part and a second cylindrical body part.

    • The invention is an explosively formed projectile (EFP). On detonation of an explosive charge, an explosively formed projectile is formed from two separate metal elements, an open-poled dished liner and a cavitation pin. The open-poled dished liner is made of a metal more dense than a metal of the cavitation pin. The cavitation pin lies on the open-poled dished liner longitudinal axis and in contact therewith. The cavitation pin has a truncated right conical shape with a base diameter to length ratio of 0.7:1 to 1.5:1. The ratio of the open-poled dished liner diameter:cavitation pin fore portion major base diameter is 2:1 to 4:1. Upon detonation, the cavitation pin leads the explosively forged liner in the explosively formed projectile assembly. The leading pin causes cavitation in water resulting in an increase in the velocity of the explosively formed projectile.
    • 本发明是一种爆炸​​成型的弹丸(EFP)。 爆炸炸药爆炸时,由两个分开的金属元件,开放的碟形衬垫和空穴针形成爆炸成型的弹体。 开放的碟形衬垫由比空穴针的金属更致密的金属制成。 空穴针位于开放的碟形衬垫纵向轴线上并与其接触。 空穴针具有基本直径与长度之比为0.7:1至1.5:1的截头圆锥形。 开孔碟形直径:空穴针前部主底径的比例为2:1至4:1。 在爆炸时,气蚀针引导在爆炸形成的射弹组件中的爆炸性锻造衬里。 引导销在水中引起气蚀,导致爆炸形成的弹丸的速度增加。
