DETAILED DESCRIPTION

[0025] A heat sink lamp for subway bow net, see Figure 1-Figure 5 , which includes a fill light 10, a cooling fan 20, and a radiator 30;

[0026] The fill light 10 includes a lamp holder 11 and a front cover 12. A lamp body (not shown) is disposed in the inner cavity of the lamp holder 11.

[0027] The heat dissipation fan 20 includes a fan outer frame 21, a motor 22, and a fan blade assembly 23. The inner cavity center plate 211 of the fan outer frame 21 is connected to the outer body 213 of the fan outer frame 21 through a ring-shaped connecting rod 212. The inner cavity center plate 211 is fixedly mounted with the motor 22. The center sleeve of the fan blade assembly 23 is fixedly sleeved on the output shaft 221 of the motor 22. There are a lot of space intervals between the several ring-shaped connecting rods 212, which allows the wind fanned out by the blades of the fan blade assembly 23 to directly act on the heat sink 32 to form an air cooling passage.

[0028] The heat sink 30 includes a connecting plate 31 and a heat sink body 32. The connecting plate 31 is provided with a plurality of first connecting holes 311 for fixing the lamp holder 11 and a plurality of second connecting hole columns 312 for fixing the fan outer frame. The heat sink bodies 32 are all protruding from the rear surface of the connecting plate 31 to form a plurality of heat dissipation fin structures. The rear end surface formed by the heat sink body 32 is an equivalent plane.

[0029] The front cover plate 12 is covered on the front end face of the lamp holder 11, the first bolt 40 fixes the connecting plate 31 and the lamp holder 11 through the first connecting hole 311, the front end face of the fan outer frame 21 is arranged close to the rear end face formed by the heat sink body 32, the second bolt 50 fixes the outer periphery of the fan outer frame 21 and the second connecting hole column 312, and when the motor is powered on, the fan blade assembly 23 fans toward the heat sink body 32.

[0030] In specific implementation, the heat sink body 32 is divided into four groups of sections, each of which is arranged with a number of heat sink fins with the same orientation, which ensures stable and reliable heat dissipation. The heat sink body 32 is arranged to avoid the positions corresponding to the first connection hole 311 and the second connection hole column 312;

[0031] Two groups of wire through holes 313 are also provided on the connecting plate 31. The circuit of the lamp body is connected to the wires of the motor 22 through any group of wire through holes 313, and the wires of the motor 22 are connected to an external power supply, which enables the lamp body and the motor 22 to work or stop at the same time, ensuring stable and reliable heat dissipation.

[0032] In a specific implementation, the surface where the lamp holder 11 and the heat sink 20 are connected is made of metal, and the heat sink 20 is made of metal, which has good heat dissipation.

[0033] The outer corners of the front cover 12 are provided with locking connectors 13, which are used to connect with the external component housing, so that the assembly of the entire heat sink lamp is fast and reliable.

[0034] The working principle is as follows: the heat emitted by the lamp body is conducted to the radiator through the rear surface of the lamp holder, and then dissipated through the heat sink body, because the heat dissipation fan blows directly to the heat sink body.
