Description

Technical Field

[0001] The invention belongs to the technical field of aviation lighting equipment, and in particular relates to a structure of an in-cabin control light. Background Art

[0002] With the continuous development of lighting technology, higher requirements have been put forward for the comprehensive performance of airborne lighting equipment at home and abroad. In addition to higher requirements for its basic functional performance (such as light performance, control performance and appearance characteristics, etc.), human-machine efficiency (operability, comfort, etc.) has also been gradually included in the consideration of product performance. In the aviation field, cabin lighting includes general lighting, local lighting and signal lights. Local lighting such as reading lights, control lights, and side panel lights are used to illuminate a specific area in the cabin. Console lighting is usually fixed due to the special working environment of the aircraft, but the fixed illumination area and constant brightness of the light cannot adapt well to certain working scenarios of the staff.

[0003] Conventional indoor reading lights of the same type mostly use damping structures, which are not suitable for relatively harsh working environments in the cabin. For example, under intense turbulence and vibration, the lamp head is easy to sag and deviate from the original irradiation direction. Fixed lamps have a limited irradiation range. When used on a narrow and long console, they can only illuminate a part of the area, leaving a dark area. According to the current development level of lighting products at home and abroad, the use of lamps with large scattering angles can also solve this problem, but large scattering angles will inevitably affect the comfort of the staff, causing dazzling phenomena and low usability. Summary of the invention

[0004] In view of this, the structure of the cabin control light provided by the present invention solves the technical problem that the traditional structure has low usage function.

[0005] A structure of an in-cabin control light, suitable for cabin lighting, comprises a shell, a light source assembly and a light source adjustment assembly, wherein the light source assembly is electrically connected to the light source adjustment assembly, the light source assembly comprises a luminous light source, wherein the light source assembly is rotatably mounted at one end of the shell for adjusting the irradiation direction of the light source; the light source adjustment assembly is rotatably mounted at the other end of the shell for adjusting the luminous intensity of the light source.

[0006] Beneficial Effects

[0007] This structure enables the lamp to adjust the direction of the light source and lock at any position. It also has the function of adjusting the brightness, achieving blind-angle lighting and brightness adjustment on the console without glare. It has strong environmental adaptability and operability, and has certain reference significance for the design of cabin console lighting. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figures 1 to 4 The structure of the cabin control light shown is suitable for cabin lighting, and includes a housing, a light source assembly and a light source 2 adjustment assembly, wherein the light source assembly is electrically connected to the light source 2 adjustment assembly, and the light source assembly includes a light source 2 that emits light, wherein:

[0020] The light source assembly is rotatably mounted at one end of the housing to adjust the irradiation direction of the light source 2. The light source 2 adjustment assembly is rotatably mounted at the other end of the housing to adjust the luminous intensity of the light source 2. Specifically:

[0021] 1) Light source components

[0022] The outer shell includes a first shell 11, and the light source assembly includes a lamp holder shell, a lampshade 33, a pressure plate 34 and a latch assembly. The light source 2 is a printed circuit board type light source 2 with a resistor. The lamp holder shell includes a trumpet portion 31 with a hollow structure and a spherical portion 32 with an axial gradient groove 100 (the spherical portion 32 is not a complete sphere, a small part of one end is cut off, and its axial cross-section is a circular surface, which is convenient for its assembly. The gradient groove 100 is used for wiring and protecting the light source 2). The gradient groove is used for wiring, and it plays a role in protecting the trumpet portion 31 and reducing its weight. The trumpet portion 31 and the spherical portion 32 are arranged in an integrated structure and are not connected. The trumpet portion 31 is hollow and has an open large end. The light source 2 is installed on the inner side of the small end of the trumpet portion 31, and the large end is installed with a lampshade 33 through a pressure plate 34. The lampshade 33 is used to prevent impurities in the environment from falling on the light source 2;

[0023] The first housing 11 includes an integrally structured and interconnected gradient portion 111 and cylindrical portion 112. The inner annular surface of the gradient portion 111 matches the shape of the spherical portion 32. The spherical portion 32 is assembled in a universally rotatable manner to achieve universal rotation of the light source 2, that is, the pitch and left-right adjustment of the lamp housing can be achieved. The cylindrical portion 112 is hollow and has openings at both ends. Oblique holes 113 are provided at intervals on the outer circumference of the cylindrical portion 112. The oblique holes 113 are used to assemble the latch assembly, wherein:

[0024] The external force rotates the latch assembly, which can limit or release the universal rotation of the spherical portion 32 in the gradient portion 111 .

[0025] Furthermore, the light source assembly also includes a rubber pad 35, which is installed on the inner end surface of the small end of the horn part 31, and the light source 2 is installed on the rubber pad 35. The rubber pad 35 is used to protect the light source 2, and the light source 2 is electrically connected to the light source 2 adjustment assembly.

[0026] The latch assembly includes a first adjusting knob 41, a pin 42, a butterfly spring 43 and a special nut 44 with a step structure or a T-shaped structure, wherein:

[0027] The first adjusting knob 41 includes a threaded portion 411 and a tapered portion 412 (with a Figure 1 As a reference, it gradually expands from top to bottom. Figure 3 As a reference, the tapered portion 412 is gradually changed from left to right), the threaded portion 411 is matched with the cylindrical portion 112 in a threaded manner, and rotating the threaded portion 411 can drive the tapered portion 412 to move axially along the housing;

[0028] A first step 45 and a second step 46 are provided in the axial direction of the inclined hole 113 , wherein the first step 45 is away from the spherical portion 32 and close to the outer annular surface of the cylindrical portion 112 ;

[0029] A ring ear 421 is provided at one end adjacent to the pin 42, and two ends of the spring 43 are respectively stopped at the step surface of the first step 45 and one side surface of the ring ear 421;

[0030] A nut is fixedly mounted on one end of the pin 42 facing the lamp housing and has an extended section. The extended section and the lamp housing can limit or release the universal rotation of the spherical portion 32 under the action of the conical portion 412;

[0031] The second step 46 can limit the axial movement of the special nut 44 toward the first adjusting knob 41 and along the inclined hole 113, thereby preventing the pin 42 from escaping from the inclined hole 113, and always keeping the outer end of the pin 42 against the inner conical surface of the first adjusting knob 41 to prevent the latch assembly from shaking freely in a loose state. Preferably, an arc-shaped protrusion 422 is provided at one end of the extended section, and the arc-shaped protrusion 422 can increase the contact area with the spherical portion 32, thereby increasing the limiting force applied to the spherical portion 32.

[0032] by Figure 3 Taking the placement as a reference, the first adjusting knob 41 is rotated counterclockwise, and the tapered portion 412 gradually moves to the left, without squeezing or pressing down one end of the pin 42. At this time, the contact portion between the other end of the pin 42 and the spherical portion 32 is in a relaxed state, that is, the artificial ball can universally rotate the spherical portion 32. Similarly, when the first adjusting knob 41 is rotated clockwise, the tapered portion 412 gradually moves to the right, pressing down one end of the pin 42, so that the other end of the pin 42 is in close contact with the spherical portion 32, which can generate a certain force and limit the rotation of the spherical portion 32.

[0033] Furthermore, the length of the first adjusting knob 41 is smaller than the length of the cylindrical portion 112 , so as to avoid excessive contact between the first adjusting knob 41 and other parts and reduce gas wear and consumption.

[0034] 2) Light source 2 adjustment component

[0035] The light source 2 adjustment component includes a circuit board 50, and the second housing 12 is installed with a circuit board for controlling the light intensity of the light source 2 and providing electrical energy. The housing includes a second housing 12, which has two openings at both ends and a hollow structure, and one end of the second housing 12 is detachably connected to the cylindrical portion 112. Specifically,

[0036] The light source 2 adjustment component further includes a potentiometer 51, a second adjustment knob 52, and an end cap 53. The housing further includes a third shell 13. The potentiometer 51 is electrically connected to the circuit board.

[0037] The other end of the second housing 12 is detachably connected to one end of the third housing 13. An end cap 53 is fixedly installed in the third housing 13. The central area of ​​the end cap 53 is used for installing a potentiometer 51. The extended shaft of the potentiometer 51 passes through the end cap 53 and is connected to the second adjusting knob 52 in a plug-in manner.

[0038] There is a gap between the second adjusting knob 52 and the other end of the third shell 13. Turning the second adjusting knob 52 can adjust the resistance value of the potentiometer 51, thereby adjusting the voltage value or current value transmitted by the circuit board to the light source 2, thereby realizing the control of the luminous intensity of the light source 2, that is, by changing the resistance value of the potentiometer 51, the current flowing through the light-emitting diode is adjusted, and then its light intensity output is adjusted, thereby changing the bright and dark state of the light source 2.

[0039] Furthermore, a notch (not marked in the figure) is provided in the circumference of the third housing 13, and the notch is used for installing the bracket 14, and the bracket 14 can support the housing. The light source 2 is preferably an LED light source.

[0040] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
