New description: [New technical field] The present invention relates to a warning light, in particular to a warning light suitable for mounting on a bicycle frame, and a light guide tube of the warning light. [Prior Art] Generally, bicycles are designed to lack good power supply, so they cannot provide good lighting and warning effects. In order to improve the safety of bicycles while driving, various kinds of lighting devices and warning lights appear on the market. A warning light suitable for being mounted behind the bicycle frame is usually provided with a light bulb inside the lamp housing or a plurality of electrically connected light emitting diodes (LEDs), and then a front side of the lamp housing is provided for allowing a light shield that is transmitted through the light. When the warning light is mounted behind the bicycle frame, the warning effect can be achieved by the flashing of the light-emitting element. Although the warning light can be used to generate a warning light source, in order to achieve the above purpose, it is necessary to install a light bulb with a high brightness but a large power consumption inside the lamp housing or to be electrically connected by a plurality of light emitting diodes. Completed, so it consumes a lot of power. On the other hand, the light source generated by the conventional warning light will be concentrated and projected from the same aspect. Not only the area of the warning is narrow, but also the light source is not visible behind and on both sides of the warning light. Therefore, the conventional warning light not only consumes The power is large, the battery needs to be replaced frequently, and the warning effect is not satisfactory. [New content] The purpose of the novel is to provide a warning light that achieves better warning and safety effects with lower power consumption, and a light guide tube of the warning light. The warning light of the present invention is suitable for mounting on one of the bicycle frames, and includes 3 M431116 ^ - a base unit mountable on the frame, a power supply unit mounted on the base, and at least one a light guide tube mounted on the base unit at an adjustable angle, the light guide tube comprising a light transmission tube housing having a housing chamber, and a guide mounted in the housing of the light transmission tube housing A light strip, and a light-emitting element electrically connected to the power supply unit and projecting a light source to the light guide strip. The beneficial effect of the novel is that the innovation of the foregoing structure is not only low in power consumption, but also the light guide strip can be used to diffuse the point light source generated by the light-emitting element into a light source that can be transmitted by the light-transmitting tube shell at 36G degrees. Improve the warning and safety of warning lights. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 1, 2, and 3, a preferred embodiment of the present warning light is suitable for being mounted behind a bicycle frame (not shown) for use as a bicycle taillight. Of course, the warning light can also be used in other In the case of the bicycle, the warning light is not limited to the bicycle frame. The warning light contains ^ base units that can be hung on the frame! a power supply unit 2, a retroreflective sheeting 3 mounted inside the base unit 1, and a -th-light guiding tube 4 and a second guiding unit mounted on the base unit 1 at an adjustable angle Light tube 4, the base unit of this embodiment! The utility model comprises a rectangular base ^, and a mounting seat 12 M431116 of the base 11 detachably mounted on the frame. How to insert and disassemble between the base 11 and the mounting base 12 It is not the focus of this new improvement and will not be described in detail. The susceptor 11 of the present embodiment has a light-transmissive front base wall 111, a surrounding wall 112 extending around the front base wall 111 and extending backward, and a section connected to the surrounding wall 112 and parallel to the front base wall m. a partition wall 113, an assembly space 114 interposed between the front base wall 111 and the partition wall of the partition, a battery compartment n 5 located behind the partition 113 of the zone, and two pairs of symmetrically spaced front and rear clamping walls 116, and A battery cover in the rear of the surrounding wall 112 is assembled by a screw 13 having two adjacent upper and left-handed wire through holes 118, and the front base wall 111 has an installation in communication with the assembly space 114. Hole 119. The power supply unit 2 of the present embodiment includes a circuit board 21 mounted in the assembly space 114 of the base, a switch 22 electrically connected to the circuit board 21 and protruding from the mounting hole 119 of the base 11, and two a first conductive sheet 23 electrically connected to the circuit board 21 and protruding toward the battery chamber 115, and a second conductive sheet 24 mounted in the battery chamber 115 and spaced apart from the first conductive sheets 23, And a battery pack 25 detachably mounted between the first conductive sheets 23 and the second conductive sheets 24. The retroreflective sheeting 3 of the present embodiment is mounted in the assembly space 114 of the base 11 and adjacent to the front base wall 111 of the base n. The first light guide tube 4 and the second light guide tube 4 of the present embodiment have the same configuration, and only the first light guide tube 4 will be described below. The first light guide 4 includes a light-transmissive tube 41 having a container chamber 4, a clamping wall 116 passing through the same side of the base 11, and the light-transmissive tube 41 is a pivoting member 42 mounted on the base 1 , a light guiding strip 43 solidly mounted in the housing 40 of the 5 M431116 light transmitting envelope 41, and a cable 45 The light-emitting element \4 electrically connected to the circuit board u of the power supply unit 2, the electric wire 45 is passed through the assembly space m by one of the electric wire perforations ι 8 of the susceptor u, and the illuminating element 44 is adjacent The end face of the light guiding strip. The light guiding light of the light guiding strip 43 and the light transmissive design of the light transmitting tube shell can cause the light source generated by the light emitting element 44 to be projected in a 36 degree manner. Referring to Figures 1, 3 and 4, when the warning light of the embodiment is in use, the base can be mounted on the frame of the bicycle by the mounting seat 12 as the first light guide 4 and the second When the light-emitting elements 44 of the light-guiding tube 4' are energized, the point light sources generated by the light-emitting elements 44 can be diffused into the 36G degrees by the light-transmitting tube shell 41 by the guide light of the light guides. The strip light source that comes out 'to achieve the enlarged light-emitting area and area (4). In addition, the first and second light guides f 4, 4' of the present embodiment can also adjust the illumination angle thereof by the connector 42 respectively, that is, the first light guide tube 4 and the second light guide. The lamp tube 4' can be horizontally expanded as shown by the solid line in FIG. 4, or can be inclined as shown by the imaginary line of FIG. 4, thereby changing the illumination direction and angle of the light source, and the foregoing structure is further mounted on the base. 11 (4) Compared with 3, it can effectively improve the safety of the bicycle with the warning light when driving.
