Long, two-bank use Μ 3 . Small size ... and many other advantages - make the LED, the application level is more and more wide. This application level includes lighting, traffic numbers, display devices, optical mice, etc. However, since the light-emitting diode is a point source, as the intensity of the light is higher, 冋' will concentrate the light with a very high intensity at the point of 0. When the source is used for the same way, It is expected that the human eye directly looking at the light source feels uncomfortable, that is, glare is generated, and the visual comfort is lowered. Due to the increasing power and brightness of the illuminating-pole n, the improvement of visual comfort is more important. In general, to enhance visual comfort, a diffuser or other light-conducting π piece can be placed in the light-emitting diode to produce a light source with a relatively uniform brightness. However, when a diffusing plate or a light guiding member is used to disperse the luminance, part of the light is lost, and energy is wasted. Therefore, the best way to improve visual comfort is not only to consider the degree of dispersion of the brightness, but also to take into account the light utilization, so that the light loss is reduced as much as possible, thereby saving energy. 6 Dispersed Ο ❾ 200930944 f Inventive content j Light source light source device' can provide brightness more light / original, and has a higher light utilization.

IS is a cross-sectional view of a light source device according to a fifteenth embodiment of the present invention: printing, according to FIG. 15, the light source device of the present embodiment is similar to the light source two, 1001 (shown in FIG. 13), both of which are The differences are as follows. In the light source device, the light source module has a light guide column 2 which does not have the first surface flaw of the crucible, and the second surface 350 is directly connected to the first end surface 310. 25 200930944 JL hexa f embodiment FIG. 16 is a perspective view of a light guiding column in a light source device according to a sixteenth embodiment of the present invention. Referring to Fig. 16, the light guiding rod 21〇0 of the present embodiment is similar to the above-mentioned light guiding rod 210m (as shown in Fig. 14A), and the difference between the two is as follows. In the light guide column 21A, the second end face 320A includes a plurality of sub-end faces 324a, 324b. In this embodiment, each of the sub-end faces 324a, 324b is a flat surface, and the refreshing angle of the adjacent two sub-end faces 324a, 324b in the light guiding column 210A is greater than the twist and less than 180 degrees. Further, the connecting surface 430 is connected between the sub-end surface 324a and the light-emitting surface 330, and is connected between the sub-end surface 32 and the light-emitting surface 330. However, in other embodiments, the sub-end faces of the second end face may also be curved. The invention does not limit a light source device to only have a light source module. In other embodiments, a light source device can also have a plurality of light source modules. The following two embodiments will be described in detail. • Soil-returning soil embodiment Fig. 17 is a front elevational view showing the light-emitting device of the seventeenth embodiment of the present invention with the light-emitting surface of the light guiding rod facing forward. Referring to Figure 17, the light source device 1 〇〇p of the present embodiment includes a plurality of the light source modules 200. The light guiding columns 21 of each light source module 200 extend along a first direction m, and the light guiding columns 210 of the light source modules are arranged along a second direction D2 perpendicular to the first direction D1. In this embodiment, each light source module 2 is electrically connected to and connected to H 11G. In addition, each of the light source modules 2 (8) and the electrical connector 11 can be fixed by a fixing frame (not shown). 26 200930944 Figure π is a front elevational view of the light source device of the eighteenth embodiment of the present invention with its light guiding surface facing the light. Referring to Fig. 18, the light source device 100q of the present embodiment is similar to the above-described light source device loop (shown in Fig. 17), and the difference between the two is as follows. These light guides 2 (4) of the light source device 200 are arranged along the first direction m (i.e., the direction in which each of the light guide columns 210 extends). It should be noted that the present invention does not limit the arrangement of the light source modules. In other embodiments, the light source modules may also be arranged in an arrangement different from the above two modes. Further, the light source device 100p and the light source module 2GG# in the light source device q can be replaced with the other practical light source modules described above to form a plurality of different light source devices. As described above, in the light source device according to an embodiment of the present invention, the light-emitting guide light (4) emitted from the light-emitting element is converted into a strip-shaped ❹% source which is relatively dispersed in brightness, thereby increasing visual comfort. In addition, the light that is off-axis from the optical axis of the light-emitting element can be totally reflected by the first surface or the annular surface. The reflective unit disposed on the first surface or the annular surface reflects, so the light that is off-axis Can still be effectively utilized, thereby improving the light utilization rate of the light source nightmare. In the light source of the embodiment of the present invention, the first end surface of the guide may be provided with an optical microstructure, an annular concave or a concave surface to enhance the proportion of light emitted by the light-emitting element into the light guide column. Improve the light utilization rate of the light source device. Although the present invention has been disclosed in the above embodiments in various embodiments, it is not intended to be used by those of ordinary skill in the art in the field of the invention, and may be modified and retouched in the spirit and scope of the invention.
