Device for eliminating overlapping shadow or track shadow of point light source

Abstract

The invention discloses a device for eliminating an overlapping shadow or a track shadow of a point light source, wherein, the periphery of the point light source is provided with a medium component which is provided with a light inlet surface and a light outlet surface that are both cambered surfaces that can scatter light; the point light source is assembled in the medium component, and the light generated by the point light source is input from the light inlet surface of the medium component and then emitted from the light outlet surface so as to diffuse the light into uniform distribution by the medium component, thus eliminating the overlapping shadow or the track shadow which is possibly generated when most devices for eliminating the overlapping shadow or the track shadow of the point light source approach the setting and which causes visual discomfort; in addition, the medium component can add required fluorescent materials according to the color of the point light source to project expected light of mixed colors.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a device which can solve the problem of visual discomfort caused by ghosting or trailing shadows easily generated when LED (light-emitting diode) light sources are arranged in a concentrated manner. Background technique [0002] Generally based on the characteristics of power saving and long service life, coupled with the improvement of luminous brightness technology, the application of LEDs in lighting has become the current optical and future trend. Due to the small size of the LED, the luminous lumens of a single LED cannot be compared with ordinary tungsten bulbs, fluorescent lamps or existing lighting fixtures. Therefore, the current LED lighting fixtures are all integrated with multiple LEDs. Practical lighting brightness is produced by concentrated light emission. [0003] Concentrating multiple LEDs in a specific area can achieve the same lighting effect as ordinary lamps, but i...

AI Technical Summary

Problems solved by technology

[0003] Concentrating multiple LEDs in a specific area can achieve the same lighting effect as ordinary lamps, but its disadvantage is that LEDs are point light sources. In terms of light distribution, the center of the LED has the highest brightness, and the light source is too concentrated. Therefore, when two or more LEDs are used at the same time, it is easy to form double shadows or trailing shadows. Under this lighting environment, the eyes are easily affected by the double shadows or trailing shadows, causing eye discomfort and dizziness.
