Abstract

The present invention relates to an optical system, which includes a lens and a prism, the lens includes a first light-emitting surface, a bottom surface opposite to the first light-emitting surface, and an annular side surface connecting the first light-emitting surface and the bottom surface, And the lens is recessed from the bottom surface in a direction adjacent to the first light-emitting surface to form a receiving groove for accommodating the light emitting diode light source, and the lens has a first light-incident surface corresponding to the bottom of the receiving groove; Two light-incident surfaces and a second light-exit surface, and the light-incident surface of the prism is provided with a plurality of triangular strip grooves arranged in an array, and the prism has a first refraction surface and a second refraction surface connected to each other corresponding to each strip groove. Two refraction surfaces, and the prism has a first side and a second side, the first side and the second side are symmetrical to the central axis of the prism. The invention also relates to an illuminating device using the optical system. The illuminating device can meet the requirements of spotlighting in directions separated by a certain angle at the same time.

Description

technical field [0001] The invention relates to the field of illumination, and further relates to an optical system and an illumination device using the optical system. Background technique [0002] As traditional incandescent bulbs gradually fade out of the historical stage, the fourth-generation solid-state light source represented by Light Emitting Diode (LED) has gradually established its core leadership in the lighting field. At present, LED has become one of the most competitive new light sources in the 21st century due to its advantages of high efficiency, pure light color, low energy consumption, long life, and no pollution. With the continuous improvement of LED luminous flux and luminous efficiency, the application of LED in the field of lighting is becoming more and more extensive. However, the light emitted from the surface of the LED chip has a Lambertian distribution, which cannot be directly applied to the lighting system. Therefore, the design of the optical...
