Problems solved by technology

But this will lead to an increase in the cost of the aforementioned light source
[0005] In addition, since only one light emitting diode 110 is used as the light source in the traditional light source, this will cause the light generated near the light emitting diode 110 to be relatively bright; , the resulting light is dimmer
As a result, the luminosity produced by this traditionally produced light source is not uniform

Abstract

The present invention discloses a light guide bar with a patterned surface for a flicker free light source comprising a light emitting diode (LED) light source disposed on each end of the light guide bar. A light diffusing pattern is disposed on a light emitting surface. The light diffusing pattern comprises a plurality of notches that are smallest closest to the LED light sources and largest in the center of the light guide bar. A light reflecting pattern is disposed on a light reflecting surface opposite the light diffusing pattern on the light emitting surface. Light emitted by the LED light sources enters the light guide bar through the ends. The light travels through the light guide bar at various angles and is reflected by the light reflecting pattern on the light reflecting surface. The reflected light is then emitted through the light diffusing pattern on the light emitting surface.

Description

technical field [0001] The invention relates to a patent related to a light source, in particular to a light source device with high efficiency and no flicker, which can provide a uniform emission of light. Background technique [0002] Linear lights emit light in different directions from the original light source. For example, a light-emitting diode emits light at an angle of zero degrees. By influencing the direction of the beam, the linear light source can also emit light at different angles, eg 90 degrees. [0003] refer to figure 1 , which is a light source diagram described in the prior art. Such as figure 1 As shown, the conventional light source includes a light emitting diode 110 and a transparent light rod 120 . Both ends of the transparent light rod 120 are flat surfaces. When the LED 110 is powered on, the LED 110 generates light. Part of the light enters the transparent light rod 120 . Since both ends of the transparent light rod 120 are flat surfaces, ...
