Abstract

The invention discloses an LED (light emitting diode) asymmetric light distributing device. The LED asymmetric light distributing device comprises a reflective light distributing mirror. The reflective light distributing mirror is fixed relative to LED luminous chips; by the light distributing mirror, light emitted from the LED luminous chips is symmetrically distributed in a direction after being reflected, the peak strength is in a range deviated from a center shaft at an angle of 35-65 degrees, and the light is asymmetrically distributed in a direction which is perpendicular to the direction in which the light is symmetrically distributed; the peak strength of the light on one side of the light distributing mirror is in a range deviated from the center shaft at an angle of 5-20 degrees; the peak strength of the light on the other side of the light distributing mirror is in a range deviated from the center shaft at an angle of 25-55 degrees; and in a range deviated from the center shaft at an angle within 5 degrees, the strength is 10-40% of the peak strength. By the LED light distributing device, reflective asymmetric light distribution can be realized, and the lamp has attractive appearance while requirements on illumination are met.

Description

technical field [0001] The invention relates to the technical field of light distribution, and more specifically, relates to an LED asymmetrical light distribution device and an LED lamp using the light distribution device. Background technique [0002] LED has developed rapidly in recent years and has been widely used in automotive, outdoor, indoor, signal and other fields. Due to the small size of LED and relatively fixed luminous characteristics, it has greater design freedom than previous light sources. The light distribution characteristics of LED lamps There are two types of symmetric distribution and asymmetric distribution. At the same time, people also have higher requirements for the aesthetics of LED lamps, which increases the difficulty of light distribution. Contents of the invention [0003] The object of the present invention is to provide an LED asymmetrical light distribution device and an LED lamp using the light distribution device. Through light distri...
