Abstract

The invention discloses a light source device which comprises at least one light source module. The light source module comprises a light guiding pole and at least one first light-emitting component. The light guiding pole is provided with a first end surface, a second end surface, a light-emitting surface, a first surface and a second surface. The second end surface is opposite to the first end surface. The light-emitting surface is connected between the first end surface and the second end surface. The first surface is connected to the first end surface, opposite to the light-emitting surface and inclined or parallel relatively to the light-emitting surface. The second surface is connected between the first surface and the second end surface, opposite to the light-emitting surface, and inclined or parallel to the light-emitting surface. The first light-emitting component is configured beside the first end surface and shines out a first light beam appropriately. The first light beam enters the light guiding pole by the first end surface and is propagated outside the light guiding pole by the light-emitting surface.

Description

technical field [0001] The invention relates to a light source device, and in particular to a light source device using a light guide rod. Background technique [0002] With the advancement of semiconductor technology, the power that light-emitting diodes (LEDs) can achieve is increasing, and the intensity of the light emitted is getting higher and higher. Long life, environmental protection, fast start-up, small size, etc., make the application level of light-emitting diodes more and more extensive. This application level includes lighting, traffic signs, displays, optical mice...etc. [0003] However, since the light emitting diode is a point light source, as the luminous intensity becomes higher and higher, the light with extremely high intensity will be concentrated on one point. When such a point light source is used for general lighting purposes, it is easy to cause discomfort to human eyes looking directly at the point light source, that is, glare is generated, and ...
