[0011] Figure 1 It is a structural schematic diagram of an embodiment of the present utility model.

[0012] Figure 2 This is a structural assembly diagram of an embodiment of the utility model (stainless steel housing and stainless steel lampshade are omitted). DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0014] See Figure 1 and Figure 2 The figure shows a nuclear power plant nuclear island LED ceiling light. The working environment of the nuclear power plant nuclear island LED ceiling light may be a nuclear radiation environment.

[0015] The nuclear island LED ceiling light of a nuclear power plant comprises: a stainless steel shell 1, a stainless steel lampshade 2, etc.

[0016] The stainless steel housing 1 comprises a peripheral wall, a top wall, and an internal housing space enclosed by the peripheral and top walls. The internal housing space is downwardly open. Within the internal housing space are located a light panel heat sink 3, a connecting plate 4, a cooling fan 5, a power supply 6, and the like. A row of heat dissipation holes 11 is formed on the peripheral wall. These rows of heat dissipation holes 11 are divided into upper and lower rows. These rows of heat dissipation holes 11 communicate with the internal housing space.

[0017] The bottom surface of the light board heat sink 3 is formed with a downwardly opening heat sink groove. An LED light board 31 and a light-transmitting plate 32 are located within the heat sink groove. The LED light board 31 abuts against the bottom of the heat sink groove, i.e., the two are in surface contact. The LED light board 31 emits light downward. The light-transmitting plate 32 covers the bottom of the LED light board 31. Preferably, the light-transmitting plate 32 can be a radiation-resistant light-transmitting plate.

[0018] The connecting plate 4 covers the top of the light board radiator 3. The bottom surface of the connecting plate 4 abuts against the top surface of the light board radiator 3. The connecting plate 4 and the light board radiator 3 are fixedly connected by screws.

[0019] The cooling fan 5 covers the connecting plate 4. The bottom surface of the cooling fan 5 abuts the top surface of the connecting plate 4. The cooling fan 5 and the connecting plate 4 are fixedly connected by screws. The cooling fan 5 blows air upward to remove heat from the light board radiator 3, thereby cooling the LED light board 31. The heat from the light board radiator 3 is finally discharged from the stainless steel housing 1 through the heat dissipation hole array 11.

[0020] The working power supply 6 is used to power the LED light board 31 and the cooling fan 5. The working power supply 6 is above the cooling fan 5. A heat dissipation gap is defined between the bottom surface of the working power supply 6 and the top surface of the cooling fan 5. This heat dissipation gap is designed to prevent interference with the operation of the cooling fan 5. The working power supply 6 is fixedly connected to the connecting plate 4 via connecting posts 7. The connecting posts 7 are arranged outside the cooling fan 5 to avoid interference with the cooling fan 5.

[0021] The stainless steel lampshade 2 is below the lamp board radiator 3. The stainless steel lampshade 2 is fixed to the lamp board radiator 3 via a socket 8. Specifically, the socket 8 has a socket base 81 and a socket connection ear 82 formed on the top surface of the socket base 81. The socket base 81 is below the lamp board radiator 3. The stainless steel lampshade 2 is below the socket base 81. The stainless steel lampshade 2 is fixedly connected to the socket base 81 by screws. The socket connection ear 82 is on the side of the lamp board radiator 3. The socket connection ear 82 is fixedly connected to the lamp board radiator 3 by screws.

[0022] The above merely describes the embodiments of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
