[0022] The present invention is further described in detail below by means of specific embodiments connected with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but 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 can be combined with each other as long as they do not conflict with each other.

[0023] See also Figures 1 to 2 , shown in the figure is a floodlight structure for the rear fuselage of a tanker.

[0024] The floodlight structure is mainly composed of a lamp housing 1, a lamp cover 2, a fixing pressure ring 3, a heat dissipation base 4, a driving circuit printed board 5, a bottom cover 6, a light source module 7 and a socket component 8.

[0025] The lamp housing 1 comprises a housing peripheral wall 11 and a housing connecting wall 12. The housing peripheral wall 11 defines a housing chamber that passes through from top to bottom. The housing connecting wall 12 extends outward from the top edge of the housing peripheral wall 11.

[0026] The lamp cover 2 is arranged above the housing connecting wall 12 and covers the upper opening of the housing chamber. A corrugated surface is formed on the lamp cover 2, which can refract the light emitted by the LED to the desired illuminated area and increase the uniformity of the light spot.

[0027] The fixed pressure ring 3 is arranged above the lamp cover 2. The lamp cover 2 is fixed by the fixed pressure ring 3 and the shell connecting wall 12. Preferably, a sealing gasket 9 is arranged between the lamp cover 2 and the shell connecting wall 12. The sealing gasket 9 is made of conductive silicone rubber, which can ensure the increase of the air tightness of the product and the electromagnetic sealing of the product, so that the product meets the electromagnetic compatibility requirements.

[0028] The heat dissipation base 4 is arranged below the lamp housing 1. The heat dissipation base 4 has a base top wall, a base peripheral wall 41 and a base heat sink 42. The base top wall has a top wall left portion and a top wall right portion. The top wall left portion is fixedly connected to the base peripheral wall 41. The top wall right portion is fixedly connected to the base heat sink 42. The base peripheral wall 41 defines a base chamber.

[0029] The driving circuit printed board 5 is arranged inside the bottom chamber.

[0030] The bottom cover plate 6 is fixedly connected to the base peripheral wall 41. The bottom cover plate 6 is used to cover the bottom of the bottom chamber.

[0031] The socket component 8 is disposed below the bottom cover plate 6. The socket component 8 is fixedly connected to the bottom cover plate 6.

[0032] The light source module 7 is placed inside the housing chamber. Figure 3 The light source module 7 comprises a light source fixing seat 71, a light source printed circuit board 72, an insulating sheet 73 and a reflective bowl 74. The light source fixing seat 71 is fixed on the right part of the top wall. The bottom surface of the light source fixing seat 71 is in contact with the top surface of the right part of the top wall and a thermal conductive silicone grease layer with excellent thermal conductivity is arranged between the two, which can conduct the heat of the light source printed circuit board 72 to the right part of the top wall to the greatest extent, and then to the base heat sink 42.

[0033] The light source fixing seat 71 has a fixing seat mounting surface. The fixing seat mounting surface is inclined. The light source printed board 72 is arranged on the fixing seat mounting surface so that the light beam direction of the LED of the light source printed board 72 is at an angle to the horizontal plane. In this embodiment, the angle is 16°. The insulating plate is arranged on the light source printed board 72. The reflective bowl 74 is arranged on the periphery of the LED of the light source printed board 72. The reflective bowl 74 converges the light output of the LED of the light source printed board 72 to ensure that it does not affect the sight of the pilot of the rear receiving aircraft.

[0034] In order to meet the requirements of night operations, the light source printed board 72 is arranged with white light LEDs and infrared LEDs. The white light LEDs are used in the friendly mode. The infrared LEDs are used in the concealed mode. In the friendly mode, the light intensity can reach about 13000cd, and in the concealed mode, the radiant brightness is about 8.31×10 -3 W / cm 2 Both modes can meet the lighting requirements of the rear fuselage area of ​​the aircraft, and the light spots in the illuminated area can transition evenly.

[0035] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
