Kind Code:
A1
Abstract:
A light scattering and filtering lens for a LED illuminating chip comprises an ellipsoidal lens (1) and a triangular lens (2) provided on the ellipsoidal lens (1). The triangular lens (2) is an isosceles triangle. The bottom margin of the triangular lens (2) is located on the ellipsoidal lens (1), and the other two margins are located in the middle position of the ellipsoidal lens (1). The lens improves the light distribution, and effectively regulates the size and shape of the spot, so that the light from the LED lamp is softer and more uniform, and the size of the spot satisfies the use requirement.
