Detailed Description
The present invention will be described in further detail below with reference to specific embodiments and drawings. Here, the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the respective embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1-2, an aircraft emblem light is shown mounted on the wingtips of two side horizontal stabilizers for illuminating airline signs on a vertical stabilizer.
The airplane aviation logo lamp comprises a lamp shell 1, a lamp cover body 2, a lamp face ring 3, a lamp light source assembly 4 and the like.
The lamp housing 1 has a housing top wall 11 and a housing peripheral wall 12. The housing top wall 11 and the housing peripheral wall 12 together define a housing built-in chamber having a downward opening.
A vent valve 1112 is fixed to the housing top wall 11. The air-permeable valve 111 is used for keeping the balance of the internal pressure and the external pressure of the built-in chamber of the shell.
The housing top wall 11 also holds an electrical connector 112.
The housing peripheral wall 12 has a peripheral wall inclined surface portion 121. The peripheral wall inclined surface portion 121 is inclined to the housing top wall 11 and inclined outward. Heat radiation ribs 1211 are disposed on the outer surface of the inclined surface portion 121. The heat dissipation ribs 1211 are used for dissipating heat. Preferably, the heat dissipation ribs 1211 may extend to the housing top wall 11.
The luminaire housing 2 covers the downward opening and is fixed by the luminaire bezel 3. A sealing ring 5 is arranged between the lamp shade 2 and the lamp surface ring 3. A sealing ring 5 is disposed between the lamp cover 2 and the housing peripheral wall 12. The sealing ring 5 can be made of corrosion-resistant material. By means of the double sealing of the sealing ring 5, the built-in cavity of the shell can be effectively prevented from being water and dust.
The lamp light source assembly 4 is positioned inside the built-in cavity of the shell. The lamp light source assembly 4 includes a mounting plate 41, a control PCB 42, and a light source PCB 43.
The mounting fixing plate 41 is fixed. The mounting fixing plate 41 may be fixed to the housing peripheral wall 12 or other positions by screws. The mounting plate fixing plate divides the built-in cavity of the shell into an upper part and a lower part. The installation fixing plate 41 is a sheet metal bending part, and the machining process is simple. The mounting fixing plate 41 has a fixing plate first portion 411 and a fixing plate second portion 412. The fixed plate first portion 411 is parallel to the housing top wall 11. The second portion 412 of the fixing plate is parallel to the inclined surface portion 121 of the peripheral wall. The fixing plate second portion 412 is formed with a lens mounting hole and the like.
The control PCB board 42 is parallel above the fixing plate first portion 411. The control PCB board 42 is spaced apart from the fixing plate first portion 411. The control PCB 42 is fixedly connected to the first portion 411 of the fixing plate through a first connecting post 44.
The light source PCB board 43 is parallel above the fixing plate second portion 412. The light source PCB board 43 is spaced apart from the fixing plate second portion 412. The light source PCB board 43 is fixedly connected to the second portion 412 of the fixing board through a second connecting post 45. The light source PCB board 43 has LED light sources, an optical lens 432, and others disposed on the front surface. The emergent light beam of the LED light source is emitted to the lamp shade body 2 after being subjected to light distribution treatment by the optical lens. The optical lens is a 432 secondary lens. The optical lens 432 is used for shaping the emergent light beam of the LED light source into a preset light spot, so that the light uniformity is better, the light-emitting angle processing is simpler, and the airline logo can be effectively lightened.
In order to obtain better heat dissipation effect, the back surface of the light source PCB 43 is attached to the inclined surface 121 of the peripheral wall of the housing 12, so that the heat generated by the light source PCB 43 during operation is directly conducted to the heat dissipation rib 1211 through the inclined surface 121 of the peripheral wall of the housing.
In addition, the control PCB board 42 and the light source PCB board 43 are isolated at an upper portion of the housing built-in chamber. The design aims to make the layout more beautiful and to play a role of a metal shielding cover in a relatively closed space.
Preferably, the lamp shade 2 is subjected to optical surface diffusion treatment, so that the product can achieve the target optical polarization effect.
The foregoing merely represents embodiments of the utility model, which are described in greater detail and detail, but are not to be construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
