Abstract

The invention relates to a light distribution system which comprises a lens and a transparent optical portion. The lens comprises an upper surface, a lower surface and an annular light-emitting surface, the lower surface is opposite to the upper surface, the annular light-emitting surface connects the upper surface with the lower surface, and the lens recesses from the lower surface of the same to the direction adjacent to the upper surface to form a first hollow portion used for accommodating light-emitting diode light sources, the lens is provided with a first annular light-incidence surface connected with the lower surface of the lens and corresponding to the first hollow portion and a second annular light-incidence surface connected with the first annular light-incidence surface; the upper surface of the lens extends out to form the transparent optical portion which is provided with a cylindrical light-emitting surface, the optical portion recesses from one side spaced from the lens to form a second hollow portion, and the second hollow portion is inverted-cone shaped. The invention further relates to a lighting device applying the light distribution system. The lighting device is good in shock resistance and light-emitting efficiency.

Description

technical field [0001] The invention relates to the lighting field, and more particularly to a light distribution system and a lighting device using the light distribution system. Background technique [0002] At present, Light Emitting Diode (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 light distribution system using the LED as the light source is particularly important. [0003] However, in existing practical applications, tungsten-halogen lamps are often used as light sources around milita...
