[0042] Please refer to Figures 1 to 6, an embodiment of the present utility model provides a linear light source, including: a housing 1 having a mounting groove, in which a condenser rod 2 is mounted, and a plurality of light outlets 101 are spaced apart from each other at the bottom of the mounting groove. The light outlets 101 face the condenser rod 2, and the plurality of light outlets 101 are spaced apart along the center line direction of the condenser rod 2; a first color optical fiber bundle 3, including M first color optical fiber filaments 31, and the light emitting end of each first color optical fiber filament 31 faces the light incident end of a light outlet 101; M is a positive integer, generally, M is greater than 10.
[0043] In this embodiment, the first color optical fiber bundle 3 is creatively provided, so that the first color optical fiber filaments 31 conduct light to the light outlet 101 to emit light to the condenser rod 2, thereby eliminating the need for a device with a cooling circuit board, effectively reducing the volume of the light emitting end of the linear light source, and thus the light emitting end of the linear light source can be installed in a narrower space, which is beneficial to reducing the volume of the device.
[0044] It should also be supplemented that the plurality of light outlets 101 are linearly arranged, and the light outlets can be made more slender, which is also beneficial to making the linear light emitting effect better.
[0045] Optionally, the linear light source further includes a second color optical fiber bundle 4 and a third color optical fiber bundle 5; the second color optical fiber bundle 4 includes M second color optical fiber filaments, and the light emitting end of each optical fiber filament faces the light incident end of a light outlet 101; the third color optical fiber bundle 5 includes M third color optical fiber filaments; the light outlet 101 facing the first color optical fiber filament 31 is used as the first light emitting port 1011, the light outlet 101 facing the second color optical fiber filament is used as the second light emitting port 1012, and the light outlet 101 facing the third color optical fiber filament is used as the third light emitting port 1013. The first light emitting port 1011, the second light emitting port 1012, and the third light emitting port 1013 form a set of light emitting hole groups, and several sets of light emitting hole groups are linearly arranged along the center line direction of the condenser rod 2. The first color optical fiber bundle 3 is used to transmit light of the first color. The second color optical fiber filaments are used to transmit light of the second color. The third color optical fiber filaments are used to transmit light of the second color.
[0046] Specifically, several sets of light emitting hole groups are linearly arranged along the center line direction of the condenser rod 2, which can make the first color light, the second color light, and the third color light mix more evenly and improve the lighting effect. Preferably, the light emitting color of the first color optical fiber filament 31 is red, the light emitting color of the second color optical fiber filament is green, and the light emitting color of the third color optical fiber filament is blue.
[0047] Optionally, the linear light source further includes a light supply device, which is connected to the first color optical fiber bundle 3 through an optical fiber connector. The light supply device emits light, and the light enters the first color optical fiber bundle 3 through the optical fiber connector and finally exits from the light outlet 101. It should be added that the first color optical fiber filaments 31 in the first color optical fiber bundle 3 are inserted into the light inlet of the light outlet 101. The light outlet 101 is a through hole.
[0048] Optionally, the light outlet 101 is a rectangular outlet, and the long side of the rectangular outlet is parallel to the center line of the condenser rod 2, so that the width of the emitted light spot is smaller and the length is longer. Here, the length direction of the light spot is parallel to the center line of the condenser rod 2. Therefore, the light emitted from the light outlet 101 has a better linear effect, and after being condensed by the condenser plate 2, the linear light spot is more concentratedly irradiated on the workpiece.

A first avoidance groove 111 is formed on the first housing wall 11, and a second avoidance groove 121 is formed on the second housing wall 12.

The housing 1 further includes a first positioning end plate 141 and a second positioning end plate 142, and the first positioning end plate 141 and the second positioning end plate 142 are provided with positioning grooves 1401 for positioning the ends of the condenser rod 2. Specifically, both ends of the condenser rod 2 are positioned and clamped by the first positioning end plate 141 and the second positioning end plate 142, and the condenser rod 2 does not contact the first housing wall 11 and the second housing wall 12, so as to prevent the condenser rod 2 from being deformed by the extrusion force of the first housing wall 11 and the second housing wall 12 and ensure the condensing effect.
[0050] Optionally, the housing 1 further includes a light guide plate 13, which is installed between the first housing wall 11 and the second housing wall 12, and the light outlets 101 are all arranged on the light guide plate 13. Specifically, connection channels are provided in the light guide plate 13, the connection channels communicate with the light outlets 101, the first color optical fiber filaments 31 are arranged along the connection channels, and the light emitting ends of the first color optical fiber filaments 31 face the light inlet ends of the light outlets 101. Since the light outlets 101 are hole-shaped structures, the light inlet ends of the light outlets 101 can also be referred to as the light inlet holes of the light outlets 101.
[0051] Optionally, the first housing wall 11 and the second housing wall 12 are detachably connected.
[0052] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structural or equivalent process substitutions or modifications made based on the essential concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as those directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
