as shown in fig. 7, the end surface of the lamp holder 210 is provided with a vent hole 213, and the side surface of the lamp holder 210 is provided with an air inlet hole 214.
As shown in fig. 7, the air guiding frame 230 is located at one side of the heat dissipating surface 212 of the lamp socket 210, the air guiding frame 230 has a first air guiding hole 231 formed at the periphery and a second air guiding hole 232 formed at the center, an air guiding cavity 500 (as shown in fig. 5) is formed between the air guiding frame 230 and the cavity-separating seal frame 330, and a heat dissipating cavity 600 (as shown in fig. 5) is formed between the air guiding frame 230 and the heat dissipating surface 212 of the lamp socket 210.

Next, the operation principle of the lighting fixture 10 based on the cooling semiconductor and the wind speed heat dissipation will be described below:
the LED copper substrate assembly 130 generates heat during the light emission process;
the refrigeration surface of the semiconductor refrigeration piece 220 is fully contacted with the LED copper substrate assembly 130, so that the LED copper substrate assembly 130 is refrigerated, and the LED copper substrate assembly 130 is cooled;
the heat dissipation surface of the semiconductor refrigeration piece 220 is attached to the mounting surface 212 of the lamp holder 210, and the heat generated by the heat dissipation surface of the semiconductor refrigeration piece 220 is conducted to the heat dissipation surface 212 of the lamp holder 210 (i.e. conducted into the heat dissipation cavity 600);
the fan 240 starts to work, external wind enters the wind guide cavity 500 through the wind inlet holes 214 on the side surface of the lamp holder 210 and the first wind guide holes 231 on the periphery of the wind guide frame 230, then enters the heat dissipation cavity 600 through the second wind guide holes 232 in the center of the wind guide frame 230 by the wind guide cavity 500, then enters the wind outlet cavity 400 through the ventilation holes 213 on the end surface of the lamp holder 210 by the heat dissipation cavity 600, and finally comes out through the wind outlet 111 on the wall of the barrel head 110, thereby realizing ventilation of wind and heat dissipation.
As shown in fig. 1, it is to be specifically noted that, in the lighting fixture 10 of the present invention based on the cooling semiconductor and the wind speed heat dissipation, the air inlet 214 is disposed at the lamp holder 210, and the air outlet 111 is disposed at the cartridge head 110, that is, cold air enters through the air inlet 214, and hot air after heat dissipation exits through the air outlet 111. Such a design is based on this consideration: when a person takes the lighting lamp, the lamp cap part 100 faces away to achieve lighting (i.e. the lamp cap part 100 is opposite to the human body), so that hot air can be blown out in a direction away from the human body, and hot air coming out from the air outlet 111 can not be directly blown against the human body, thereby improving the comfort of use.
As shown in fig. 3, it is further explained that the LED copper substrate assembly 130 is isolated from the air outlet cavity 400 by the reflective cup 120, and the reflective cup 120 has a heat insulation function in addition to its own reflective function, that is, the hot air reaching the air outlet cavity 400 will not return to the LED copper substrate assembly 130 again, thus reducing the load of the semiconductor refrigeration sheet 220 and prolonging the service life of the LED copper substrate assembly 130.
As shown in fig. 3, it will be further described that, because the reflective cup 120 has a truncated cone structure, the air outlet cavity 400 formed between the cup body of the reflective cup 120 and the inner wall of the barrel head 110 also has a large opening end and a small opening end, the air outlet 111 is located at the small opening end of the air outlet cavity 400, hot air enters from the large opening end of the air outlet cavity 400, flows intensively along the cup body of the reflective cup 120 to the small opening end of the air outlet cavity 400, and then flows out from the air outlet 111.
As shown in fig. 3, in the present embodiment, the lamp head part 100 further includes a transparent member 140, and the transparent member 140 is connected to the cup opening of the reflector cup 120 through a sealing ring. The transparent member 140 may be transparent glass for preventing external rainwater or dust from entering the inside of the cartridge head 110.
As shown in fig. 3, further, the lamp head part 100 further includes a pressing ring 150, the pressing ring 150 is disposed at one end of the barrel head 110, and the pressing ring 150 is used to press the transparent member 140 against the cup opening of the reflector cup 120.
As shown in fig. 2, in the present invention, the lighting fixture 10 based on the cooling semiconductor and the wind speed heat dissipation further includes a handle part 700, and the handle part 700 has a connection end 710 and a grip end 720, and the grip end 720 is connected with the stem 110 of the base part 100 through the connection end 710. The user can more conveniently hold the entire light fixture through the handle portion 700.
As shown in fig. 2, further, the holding end 720 is provided with a key display control board 721, and the key display control board 721 can more intuitively obtain the parameter information of the current lighting lamp, for example, can obtain the current electric quantity information in real time.
As shown in fig. 2, in this embodiment, the barrel portion 300 further includes a tail cap 340, and the tail cap 340 is disposed at a port of the barrel 310; the tail cap 340 is provided with a charge/discharge interface 341, the charge/discharge interface 341 is electrically connected with the battery 320, and the charge/discharge operation can be performed on the battery 320 through the charge/discharge interface 341.
As shown in fig. 9, in the present embodiment, a fixing sleeve 215 is disposed on the mounting surface 211 of the lamp holder 210, a socket sleeve 121 (as shown in fig. 3) is disposed at the bottom of the reflector cup 120, the fixing sleeve 215 is provided with an annular cavity 216, and the socket sleeve 121 is plugged into the annular cavity 216 through a sealing ring. Such a structural design may allow the reflector cup 120 to be more quickly and stably mounted on the mounting surface 211 of the lamp socket 210.
As shown in fig. 8, in the present embodiment, the heat dissipating surface 212 of the lamp socket 210 is provided with heat dissipating fins 217. By providing the heat radiation fins 217, heat radiation can be performed better.
As can be seen from the above, the lighting fixture 10 according to the present invention, which is based on the cooling semiconductor and the wind speed heat dissipation, achieves the heat dissipation of the LED copper substrate assembly by the combination of the semiconductor cooling fin and the fan. In the long-term use process of the fan, thick dust is adhered to the fan blades, so that the heat dissipation efficiency is greatly reduced, and the fan blades of the fan are required to be cleaned after the lighting lamp is used for a period of time. The traditional lighting lamp needs to disassemble the shell to take out the built-in fan, so that on one hand, a great amount of time and energy are consumed in the disassembling and assembling processes, and on the other hand, the disassembly and assembling errors possibly occur due to the fact that the whole lighting lamp is scrapped.
Therefore, how to perform one-step optimization design on the structure of the lighting fixture 10 based on the refrigeration semiconductor and the wind speed heat dissipation can simply and quickly clean the built-in fan on the basis of not damaging the internal parts is a technical problem to be solved.
As shown in fig. 11 and 12, specifically, the fan 240 includes a fixing frame 241 and a fan blade 242, the fixing frame 241 has a driving shaft 243, and the fan blade 242 is connected with the driving shaft 243 in a pluggable manner;
as shown in fig. 11 and 12, the cavity-dividing sealing frame 330 is connected with the lamp socket 210 through a telescopic rod 900, so that the cylinder 310 is attached to or separated from the lamp socket 210;
as shown in fig. 11 and 12, the cavity-dividing sealing frame 330 is provided with a linkage shaft 331, one end of the linkage shaft 331 is connected with the fan blade 242, and the fan blade 242 can rotate around the linkage shaft 331;
the coupling shaft 331 pushes and pulls the fan blades 242 such that the fan blades 242 are coupled to or decoupled from the driving shaft 331.
When the fan blade 242 of the fan 240 needs to be cleaned, only the cylinder 310 needs to be simply pulled, the cylinder 310 drives the cavity-dividing sealing frame 330 to move, and the cavity-dividing sealing frame 330 is connected with the lampholder 210 through the telescopic rod 900, so that the telescopic rod 900 stretches, and the cylinder 310 and the lampholder 210 are separated from each other to form an opening 910 (as shown in fig. 10);
at the same time, the split-cavity sealing frame 330 pulls the fan blades 242 through the linkage shaft 331, so that the fan blades 242 are separated from the driving shaft 243;
in this way, the fan blades 242 are also exposed at the opening between the cylinder 310 and the lamp socket 210, so that the inside fan blades 242 can be cleaned through the opening;
after cleaning, barrel 310 is pushed back in the same direction, barrel 310 drives split cavity sealing frame 330 to move in the opposite direction, telescopic rod 900 is contracted, and then the opening between barrel 310 and lamp holder 210 is closed again;
simultaneously, the cavity-dividing sealing frame 330 pushes the fan blades 242 through the linkage shaft 331, so that the fan blades 242 are reconnected with the driving shaft 243;
when the motor is powered on, the motor drives the driving shaft 243 to rotate, and the driving shaft 243 drives the fan blade 242 to rotate, since the fan blade 242 can rotate around the linkage shaft 331, it is known that the linkage shaft 331 does not prevent the fan blade 242 from rotating normally, and the linkage shaft 331 only applies force to the fan blade 242 axially to connect or disconnect the fan blade 242 to or from the driving shaft 243.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
