The size of the outer edge of the support body 2 matches the size of the inner edge of the support part 1. The support body 2 is coaxially sleeved on the opening of the movable end of the support part 1, and the lighting module 4 is clamped in the support body 2.

[0037] The illumination module 4 of the signal light module is disposed within the support body 2, and the support body 2 is connected to the signal light housing via a support portion 1 made of an insulating material, ensuring a floating installation of the signal light module. This makes the signal transmission of the illumination module 4 less susceptible to interference, thereby reducing the failure rate of the signal light module during use.

[0038] At the same time, the above-mentioned lighting module 4 is connected to the support body 2 made of metal material, so that the high-temperature heat generated by the lighting module 4 during operation can be quickly transferred to the support body 2 and quickly dissipated through the support body 2, thereby solving the heat dissipation problem of integrating the lighting module 4 inside the support body 2.

[0039] Preferably, the interior of the above-mentioned support body 2 is encapsulated with thermal conductive sealant (not shown in the figure), so that the high-temperature heat generated by the lighting module 4 during operation can be quickly transferred to the support body 2 through the thermal conductive sealant, thereby further improving the heat dissipation effect of the signal light module.

[0040] In addition, the potting of the thermally conductive sealant can also fix the circuit inside the support body 2 to avoid the circuit breaking due to vibration, thereby increasing the service life of the signal light module.

[0041] Optimized, the above-mentioned support body 2 is provided with a cover plate 21 at one end away from the support part 1, and the cover plate 21 is a ring-shaped structure. A heat sink 22 is provided on the side of the cover plate 21 away from the support body 2. The heat sink 22 can be connected to the signal light housing to transfer the high-temperature heat on the support body 2 to the signal light housing to further improve the heat dissipation effect of the signal light module.

[0042] It should be noted that the cross-sectional shape of the support body 2 and the cross-sectional shape of the support portion 1 are both circular, and the cover plate 21 is a circular ring structure.

[0047] Preferably, a rear support frame 211 is provided on the cover plate 21, and the surface of the rear support frame 211 is coated with insulating paint to prevent the support body 2 from being connected to the signal light housing, thereby preventing interference with signal transmission.

[0048] The rear support frame 211 can be connected to the signal light housing to support the rear of the signal light module (the end of the support body 2 away from the support portion 1), making the installation of the signal light module more stable.

[0049] Optimally, the signal light module further includes an end cap 5 made of insulating material, see FIG3 ;

[0050] The end cap 5 is removably sealed at the opening of the end of the support body 2 away from the support part 1, that is, the opening on the end cap 5, to achieve sealing of the support body 2. The power cord passes through the end cap 5 and is electrically connected to the lighting module 4 to avoid direct contact between the wire and the support body 2, which may cause interference in signal transmission.

The power connection column 51 is electrically connected to the lighting module 4, and the connecting end of the power cord is fixed on the power connection column 51 by winding and fastened with a nut to prevent the power cord from falling off from the power connection column 51 and causing the signal light module to fail to work normally.
