Abstract

The invention relates to an optical system comprising a lens and another lens. The lens comprises a stepped toothed surface, a bottom surface opposite to the stepped toothed surface and an annular lateral surface connecting the stepped toothed surface and the bottom surface, the bottom surface of the lens concaves towards the direction adjacent to the stepped toothed surface to form an accommodating hole used for accommodating a light-emitting diode light source, and the bottom, corresponding to the accommodating hole, of the lens is provided with a light-incident surface. The other lens is provided with a first side and a second side which are symmetrical relative to a central axis of the lens. The invention further relates to an illuminating device adopting the optical system. The illuminating device can form bidirectional refraction light beams, and meets the requirement of spotlighting in the directions spaced by a certain angle.

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...
