Please refer to the following: Figure 2 and Figure 5 The bicycle handlebar assembly with lighting unit described in this utility model includes a handlebar 10, a stem 20, and a lighting unit 30. The handlebar 10 can be long, curved, or any shape of existing bicycle handlebars. This utility model does not limit the shape of the handlebar 10. The stem 20 is detachably connected to the handlebar 10 and mainly includes a stem body 22 and a front seat 24. The stem body 22 extends laterally relative to the handlebar 10. A clamping part 222 for clamping the bicycle fork tube is formed at the rear end of the stem body 22, and an abutment surface 224 that can abut against the rear side of the handlebar 10 is formed at the front end of the stem body 22. Several fixing holes 226 are provided at the front end of the stem body 22, and each fixing hole 226 can be a screw hole. The front seat 24 abuts against the front side of the handlebar 10. The front seat 24 has several through holes 242 that are respectively opposite to the fixing holes 226 on the vertical tube body 22. By passing several bolts 26 through the through holes 242 of the front seat 24 and screwing them into the fixing holes 226 at the front end of the vertical tube body 22, the handle 10 can be clamped between the vertical tube body 22 and the front seat 24, so that the faucet vertical tube 20 and the handle 10 can be detachably connected. A clamping groove 244 is formed on the front seat 24, in which the lamp assembly 30 can be rotatably accommodated. The inner surface of the clamping groove 244 can be a concave arc surface. A clamping piece 246 is formed on the bottom edge of the front seat 24, which can abut against the periphery of the lamp assembly 30. The inner surface of the clamping piece 246 can also be a concave arc surface. A fixing screw hole 2462 is formed on the clamping piece 246, and an adjusting bolt 28 that can be screwed into the fixing screw hole 2462 is also provided.

[0054] The lamp assembly 30 is adjustable in angle and accommodates within the clamping groove 244 of the front seat 24 of the faucet riser 20. It includes an adapter 32, a lamp 34, and two heat sinks 36. Please refer to the attached diagram. Figure 3The adapter 32 is generally a hollow tube. A lamp opening 322 is formed on the adapter 32, which penetrates the tube wall of the adapter 32. The lamp 34 is inserted through the lamp opening 322 and embedded in the adapter 32. The bottom surface of the lamp 34 can abut against the inner surface of the adapter 32. Two fasteners 38 are provided on the adapter 32, which penetrate the tube wall of the adapter 32 and are screwed into the bottom surface of the lamp 34, so as to improve the strength and stability of the connection between the lamp 34 and the adapter 32.

[0055] Furthermore, the heat sink 36 is inserted into both ends of the adapter 32. On the side of each heat sink 36 facing the lamp 34, there is a recessed groove 362 that abuts against the side of the lamp 34. The recessed groove 362 can be an arc-shaped concave surface, thereby increasing the contact area between the heat sink 36 and the lamp 34. On the other side of the two heat sinks 36, which is different from the side forming the recessed groove 362, there are a plurality of parallel heat dissipation grooves 364. On the side of the heat sink 36, there are a plurality of rough heat dissipation protrusions 366, thereby increasing the heat dissipation area of ​​the heat sink 36. In addition, two positioning bolts 39 are provided on the adapter 32, which can abut against the side of the heat sink 36, thereby increasing the bonding strength between the heat sink 36 and the adapter 32.

[0056] Please refer to the following: Figures 4 to 6 The adjusting bolt 28 of the stem tube 20 abuts against the outer surface of the adapter 32, thereby clamping and fixing the lamp 34 to the front end of the stem tube 20 via the adapter 32. In this way, the lamp 34 can be turned on at night to illuminate the road surface and improve the safety of riding a bicycle at night. In addition, the heat generated by the lamp 34 after it is turned on can also be transferred to the stem tube 20, handlebar 10 and heat sink 36 via the adapter 32. This increases the heat dissipation area of ​​the lamp 34, effectively reducing the temperature of the lamp 34 when it is turned on and preventing the lamp 34 from being damaged due to overheating after prolonged use.

[0057] Please refer to the following: Figures 7 to 9 When the adjusting bolt 28 is slightly loosened, the adapter 32 is in the shape of a round tube, so it can be rotated relative to the clamping groove 244 of the front seat 24 to adjust the lighting angle of the lamp 34 upward or downward. Then the adjusting bolt 28 is tightened to fix the lamp assembly 30 at the adjusted angle, thereby changing the lighting angle of the lamp assembly 30 to suit different users and road conditions, so as to improve the flexibility of the lamp assembly 30.
