It can be understood that the heat dissipation fin 121 is mounted on the supporting plate 111 by inserting the locating hole 12a on the fitting portion 123 into the corresponding locating post 122, so as to improve the fixing effect of the heat dissipation fin 121 and prevent it from being separated from the supporting plate 111.

[0038] Preferably, any two adjacent heat dissipation fins 121 are spaced apart to form a heat dissipation channel 13a, and the airflow can pass through the heat dissipation channel 13a to accelerate the heat dissipation of the heat dissipation fin 121. Further, the heat dissipation fin 121 is provided with a heat dissipation hole 13b, and the heat dissipation hole 13b is in communication with the heat dissipation channel 13a when the heat dissipation fin 121 is mounted on the supporting plate 111. It can be understood that the heat dissipation channel 13a extends in the second direction, and the heat dissipation fin 121 is connected in the first direction through the heat dissipation hole 13b, so that the airflow can pass through one or more heat dissipation fins 121 in the first direction, thereby accelerating the heat dissipation of the heat dissipation fin 121.

[0039] Preferably, the lamp holder 110 further comprises a supporting member 114 mounted on the heat dissipation frame 112 and arranged between any two adjacent heat dissipation fins 121, and the supporting member 114 is located at least on the circumferential side of the heat dissipation fin 121 in the second direction and / or the third direction. Optionally, the supporting member 114 is located on the circumferential side of the heat dissipation fin 121 in the second direction and the third direction in the embodiment, and the purpose of arranging the supporting member 114 is to fix the side of the heat dissipation fin 121 away from the supporting plate 111 and the two sides of the heat dissipation fin 121 in the second direction, so as to keep the spacing of the heat dissipation fin 121 stable, avoid deformation caused by accidental touch or other external force, and affect the heat dissipation effect.

[0040] Preferably, the lamp holder 110 further comprises an extension arm 115 arranged at both ends of the supporting plate 111, the supporting plate 111 is mounted between the extension arms 115, and the extension arms 115 are arranged in a spaced manner with the heat dissipation frame 112. It can be understood that the supporting plate 111 is fixed by assembling the supporting plate 111 using the extension arm 115. In addition, the lamp holder 110 comprises at least two supporting plates 111, and the lamp holder 110 in the embodiment comprises two supporting plates 111, and the two supporting plates are arranged in the second direction, so that the heat dissipation channels 13a of the heat dissipation frames 112 mounted on the two supporting plates 111 can be arranged in a facing manner in the second direction, which is more convenient for airflow circulation.
