Therefore, they should not be construed as limitations on the present invention.

[0032] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0033] like Figures 1 to 8As shown, an embodiment of the present invention provides a combined lamp, including a bracket 100, a lamp body 101, a stabilizing component 200 and a sensing module, wherein the bracket 100 is fixed on a carrier; the lamp body 101 is arranged on the bracket 100, and the lamp body 101 can switch between an active state and a static state relative to the bracket 100. When the lamp body 101 is in the active state, the lamp body 101 can change its orientation relative to the bracket 100, and when the lamp body 101 is in the static state, the lamp body 101 can lock its orientation relative to the bracket 100; the stabilizing component 200 is rotatably arranged on the lamp body 101, and the stabilizing component 200 includes a coaxial and coplanar inner ring 201 and an outer ring 202, wherein the inner ring 201 has a first cavity 203 formed therein and the outer ring 202 has a second cavity 204 formed therein. 02 is formed with a second chamber 204, the first chamber 203 is connected to the second chamber 204 and both are filled with a flowing medium, the inner ring 201 and the outer ring 202 can rotate synchronously at a first speed or a second speed, the first speed is less than the second speed, when the inner ring 201 and the outer ring 202 switch from the first speed to the second speed, the flowing medium in the first chamber 203 flows to the second chamber 204; the sensing module is used to obtain a first parameter, and the first parameter is positively correlated with the degree of shaking of the carrier. When the first parameter is less than or equal to a first preset value, the lamp body 101 is in a stationary state, and the inner ring 201 and the outer ring 202 rotate at the first speed; when the first parameter is greater than the first preset value, the lamp body 101 is in an active state, and the inner ring 201 and the outer ring 202 rotate at the second speed.

[0034] When the degree of the carrier's bumping and shaking is small, the first parameter is less than or equal to the first preset value, the lamp body 101 is in a stationary state, the inner ring 201 and the outer ring 202 rotate at a first speed, and the flow medium is relatively evenly distributed in the first chamber 203 and the second chamber 204. The mass distribution of the inner ring 201 and the outer ring 202 is relatively uniform, the angular momentum is small, and the orientation of the lamp body 101 changes slightly with the carrier; when the degree of the carrier's bumping and shaking is large, the first parameter is greater than the first preset value, and the lamp body 101 is in a stationary state. In the active state, the inner ring 201 and the outer ring 202 switch to the second speed of rotation, and the centrifugal force generated increases. At this time, the flow medium in the first chamber 203 flows to the second chamber 204, which reduces the mass of the inner ring 201 and increases the mass of the outer ring 202, thereby increasing the angular momentum and enhancing the gyroscopic effect. The stabilizing component 200 acts on the lamp body 101 to enable the lamp body 101 to resist the bumps and shakes of the carrier and maintain its original orientation, thereby reducing the impact on the light irradiation range and lighting effect of the lamp body 101.

[0035] When the carrier experiences minimal turbulence and shaking, inner ring 201 and outer ring 202 rotate at the first speed. The fluid medium can be distributed relatively evenly between first chamber 203 and second chamber 204, resulting in a more uniform mass distribution between inner ring 201 and outer ring 202. Alternatively, the fluid medium can be concentrated in first chamber 203, resulting in a greater mass between inner ring 201 and outer ring 202. In both cases, the angular momentum of inner ring 201 and outer ring 202 is smaller than when inner ring 201 and outer ring 202 rotate at the second speed.

[0036] Among them, when the carrier is a ship, the lamp body 101 is used for night navigation, search and rescue, buoy observation, etc., and it needs to stably illuminate the target without being affected by the shaking of the hull caused by waves; when the carrier is an off-road vehicle or a special operation vehicle and is driving on a rugged road, the body of the vehicle will shake violently, and the lamp body 101 needs to stably illuminate the front or the operating area; when the carrier is a helicopter and is hovering or flying in the air, the fuselage will shake due to the airflow, but the lamp body 101 needs to accurately and stably illuminate the search area; when the carrier is used for aerial photography, the lamp body 101 is used for fill light; and other usage scenarios.

[0037] Among them, the inner ring 201 and the outer ring 202 rotate around their axes. When they switch from the first speed to the second speed, the centrifugal force generated by the increase in speed increases. At the same time, the flowing medium in the first chamber 203 flows to the second chamber 204, which reduces the mass of the inner ring 201 and increases the mass of the outer ring 202. According to I=Σ(m i ·r i 2 ), where I is the moment of inertia, m i The mass of each particle, r i is the distance from the particle to the axis of rotation, the moment of inertia I increases; according to L=I·ω, where L is the angular momentum and ω is the angular velocity, the angular momentum L increases; and because the gyroscopic effect is proportional to the angular momentum L, the gyroscopic effect is enhanced, that is, the ability of the inner ring 201 and the outer ring 202 to resist changes in the direction of their rotation axes is stronger, so that the lamp body 101 is more able to maintain its original orientation.

[0038] Among them, the bracket 100 is directly fixed to the carrier by bolts, and an adjustment component is also provided on the bracket 100. The lamp body 101 is installed on the adjustment component. The structure of the adjustment component in the prior art can be as follows: the adjustment component includes a base 102, and a vertical axis 103 is provided on the base 102. The base 102 is rotatably connected to the bracket 100 through the vertical axis 103, so that the lamp body 101 can swing left and right around the vertical axis 103. A first arc-shaped groove 104 is opened on the base 102 around the vertical axis 103, and an adjustment bolt is provided in the first arc-shaped groove 104 to lock the rotation angle of the base 102 around the vertical axis 103; the base 102 02 is provided with two side rods 105, each of which is provided with a transverse axis 106. The side rods 105 are rotatably connected to the lamp body 101 via the transverse axis 106, so that the lamp body 101 can swing up and down around the transverse axis 106. An adjustment rod 107 is also provided between the lamp body 101 and the base 102. A second arc-shaped slot 108 is provided on the base 102, and the axis of the second arc-shaped slot 108 is arranged horizontally. The upper end of the adjustment rod 107 is fixed to the lamp body 101, and the lower end is provided with an adjustment bolt. The adjustment bolt is located in the second arc-shaped slot 108 to lock the rotation angle of the base 102 around the transverse axis 106. Of course, axes with other rotation directions can also be provided to give the lamp body 101 other degrees of freedom.

[0039] In addition, in order to enable the lamp body 101 to automatically switch between an active state and a static state relative to the bracket 100, an automatic control mechanism can be provided to replace the manually operated adjustment bolts in the prior art. The structure of the automatic control mechanism can be as follows: the adjustment component still includes a base 102 and a vertical axis 103 and a horizontal axis 106. Taking the vertical axis 103 as an example, a bayonet is provided on the side of the base 102 close to the bracket 100. The bayonet can be controlled to extend and retract by a telescopic cylinder. The telescopic cylinder is provided with a corresponding power source and controller. A plurality of slots are provided on the bracket 100 at equal intervals around the vertical axis 103. When the bayonet is disengaged from the slot, the lamp body 101 is in an active state. At this time, the lamp body 101 can change its direction relative to the bracket 100. When the bayonet is extended into the slot, the lamp body 101 is in a static state. At this time, the lamp body 101 can lock its direction relative to the bracket 100. The automatic control mechanism of the horizontal axis 106 is the same as the automatic control mechanism of the above-mentioned vertical axis 103. Of course, other automatic control mechanisms may also be used, such as using a telescopic cylinder to control the relative movement of the two friction rings, thereby loosening the vertical shaft 103 to allow rotation, or clamping the vertical shaft 103 to prevent rotation, thereby automatically switching the lamp body 101 between an active state and a stationary state relative to the bracket 100. The structure of the above-mentioned automatic control mechanism is prior art and will not be described in detail here. It can be selected according to needs.

[0040] Both ends of the inner ring 201 and outer ring 202 are open and equipped with corresponding covers 205 for sealing and facilitating assembly and disassembly of related components. One of the covers 205 has a filling port for adding and removing the fluid. A mounting bracket 206 is located on the back of the lamp body 101. This bracket houses a motor 207, equipped with a power supply and controller for start and stop control. The output of the motor 207 drives the inner and outer rings 201 and 202 to rotate synchronously. Both the first and second velocities are angular velocities, measured in rad / s.

[0041] Among them, the sensing module can use sensors such as accelerometers or gyroscopes to obtain the carrier's shaking amplitude in real time and convert it into a shaking signal, that is, the first parameter. The shaking amplitude is usually expressed as a multiple of the gravitational acceleration g, and its unit is m / s 2 For example, for a ship, the sway amplitude of the ship under calm water is about 0.1g, and when it is subjected to medium or above turbulence, the sway amplitude is about 0.5g or more; the first preset value can be any value above 0.3g. The bracket 100 is also provided with a processor, which is connected to the controller of the motor 207 and the controller of the telescopic cylinder in the above-mentioned automatic control mechanism to control the operation of the motor 207 and the telescopic cylinder, and the processor is connected to the sensing module. When in use, the sensing module will obtain the sway amplitude of the carrier and convert it into a sway signal, i.e., a first parameter, and send it to the processor. When the first parameter is less than or equal to the first preset value, such as 0.3g, it means that the current sway amplitude of the carrier is small. The processor controls the operation of the telescopic cylinder to keep the lamp body 101 in a stationary state. At the same time, the processor controls the output end of the motor 207 to rotate at a lower first speed, and the orientation of the lamp body 101 changes slightly following the carrier. When the first parameter is greater than the first preset value, for example 0.3g, it means that the current carrier has a large shaking amplitude. The processor controls the telescopic cylinder to run in reverse, so that the lamp body 101 is in an active state. At the same time, the processor controls the output end of the motor 207 to rotate at a higher second speed. The lamp body 101 resists the bumps and shaking of the carrier and maintains its original direction.

[0042] Preferably, the first chamber 203 is a ring-shaped opening along the contour of the inner ring 201, and a plurality of first adjustment components 208 are provided in the first chamber 203 at equal intervals along its circumference. The first adjustment components 208 divide the first chamber 203 into equal parts and are used to adjust the size of the first chamber 203; the second chamber 204 is a ring-shaped opening along the contour of the outer ring 202, and a plurality of second adjustment components 209 are provided in the second chamber 204 at equal intervals along its circumference. The second adjustment components 209 divide the second chamber 204 into equal parts and are used to adjust the size of the second chamber 204; when the flowing medium in the first chamber 203 flows to the second chamber 204, the first chamber 203 shrinks and the second chamber 204 expands.

[0043] When the inner ring 201 and the outer ring 202 rotate at the first speed, the first adjustment component 208 and the second adjustment component 209 are both in normal state, and the first chamber 203 and the second chamber 204 are both at their initial sizes; when the inner ring 201 and the outer ring 202 switch to the second speed rotation, the flowing medium in the first chamber 203 flows to the second chamber 204, the first adjustment component 208 shrinks the first chamber 203, and the second adjustment component 209 enlarges the second chamber 204 to facilitate the flow of the flowing medium.

[0044] Of course, the first chamber 203 and the second chamber 204 may both be fan-shaped.

[0045] Preferably, the first adjustment component 208 includes two first partitions 210 that slide relative to each other along the first chamber 203, the first partitions 210 are sealed and connected to the inner ring 201, and a first spring 211 is provided between the two first partitions 210; the second adjustment component 209 includes two second partitions 212 that slide relative to each other along the second chamber 204, the second partitions 212 are sealed and connected to the outer ring 202, and a second spring 213 is provided between the two second partitions 212.

[0046] When the inner ring 201 and the outer ring 202 switch from the first speed to the second speed, the flow medium in the first chamber 203 flows to the second chamber 204, the pressure in the second chamber 204 decreases, the first spring 211 extends, and the two first partitions 210 move away from each other, so that the first chamber 203 shrinks; at the same time, the pressure in the second chamber 204 increases, the second spring 213 is compressed, and the two second partitions 212 move closer to each other, so that the second chamber 204 expands.

[0047] When the inner ring 201 and the outer ring 202 rotate from the second speed to the first speed, the second spring 213 moves the second partitions 212 on both sides away from each other, causing the flowing medium in the second chamber 204 to flow to the first chamber 203. At the same time, the two first partitions 210 approach each other and the first spring 211 is compressed.

[0048] The elastic force of the first spring 211 is smaller than the elastic force of the second spring 213 .

[0049] The first partition 210 is a sector-shaped block adapted to the first chamber 203, and the second partition 212 is a sector-shaped block adapted to the second chamber 204. The centerline of the first spring 211 is an arc-shaped block adapted to the first chamber 203, and the centerline of the second spring 213 is an arc-shaped block adapted to the second chamber 204. A sealing strip is provided on the sliding surface of the first partition 210 relative to the inner ring 201, and a sealing strip is provided on the sliding surface of the second partition 212 relative to the outer ring 202.

[0050] Among them, see Figure 7 、 Figure 8Two inner synchronizer rings 214 are disposed within the first chamber 203. The inner synchronizer rings 214 are coaxially rotatable relative to the inner ring 201. The two inner synchronizer rings 214 are each provided with an equal number of first baffles 210 on their mutually adjacent sides. For example, if there are three first adjustment assemblies 208, each inner synchronizer ring 214 also has three pairs of first baffles 210, thereby enabling the three first adjustment assemblies 208 to move synchronously with the two inner synchronizer rings 214. Similarly, two outer synchronizer rings 215 are disposed within the second chamber 204. The outer synchronizer rings 215 are coaxially rotatable relative to the outer ring 202. The two outer synchronizer rings 215 are each provided with an equal number of second baffles 212 on their mutually adjacent sides. For example, if there are three second adjustment assemblies 209, each outer synchronizer ring 215 also has three pairs of second baffles 212, thereby enabling the three second adjustment assemblies 209 to move synchronously with the two outer synchronizer rings 215.

[0051] Preferably, a pull rope 216 is provided between the two second partitions 212 .

[0052] The second spring 213 maintains a certain degree of compression in the initial state, that is, it has a certain preload force.

[0053] When the first adjustment assembly 208 and the second adjustment assembly 209 are both in a normal state, the first spring 211 and the second spring 213 are both in a compressed state. However, at this time, the first spring 211 and the second spring 213 cannot further deform each other. For the second spring 213, the elastic force of the first spring 211 cannot further compress the second spring 213, and the drawstring 216, due to its lack of elasticity, cannot further stretch the second spring 213.

[0054] Preferably, a connecting piece 217 is provided between the inner ring 201 and the outer ring 202, and a connecting chamber 218 is formed in the connecting piece 217. The first chamber 203 and the second chamber 204 are connected through the connecting chamber 218. The length direction of the connecting piece 217 is set at an angle to the radial direction of the inner ring 201 or the outer ring 202, so that the flow medium can flow more smoothly between the first chamber 203 and the second chamber 204, thereby reducing the flow resistance.

[0055] The connecting chamber 218 is preferably arc-shaped.

[0056] Preferably, multiple connecting members 217 are arranged at equal intervals along the circumference of the inner ring 201 or the outer ring 202, and the number of connecting members 217 is equal to the number of first adjustment components 208 or the second adjustment components 209, so as to increase the flow speed of the flowing medium between the first chamber 203 and the second chamber 204, and at the same time make the mass distribution of the inner ring 201 and the outer ring 202 more uniform and the rotation more stable.

[0057] Preferably, two ends of the connecting member 217 are respectively disposed at the middle of two adjacent first adjustment components 208 and the middle of two adjacent second adjustment components 209 .

[0058] The flowing medium enters the first chamber 203 or the second chamber 204 from the middle, so that the flowing medium is more evenly distributed in the first chamber 203 or the second chamber 204 more quickly.

[0059] The embodiment of the present invention further provides a heat dissipation mechanism, wherein the axes of the inner ring 201 and the outer ring 202 face the back of the lamp body 101 , and the inner ring 201 and the outer ring 202 rotate to dissipate heat from the lamp body 101 .

[0060] The axes of the inner and outer rings 201, 202 can be perpendicular to the back of the lamp body 101 or at a certain angle. The inner and outer rings 201, 202 drive the rotation of multiple connectors 217, which function as fan blades, generating a blowing or suction force on the lamp body 101 to dissipate heat, thereby preventing the lamp body 101 from heating up over time, which would otherwise cause a decrease in luminous efficiency and material degradation. Furthermore, the outer contour of the connectors 217 can be configured in a fan-like shape to better generate blowing or suction force.

[0061] Of course, fan blades or grooves can also be set on the end face of the inner ring 201 or the outer ring 202 close to the lamp body 101. Multiple fan blades or grooves are set at equal intervals along the circumference of the inner ring 201 or the outer ring 202. When the inner ring 201 or the outer ring 202 rotates, the fan blades or grooves generate a blowing force on the back of the lamp body 101 to dissipate heat.

[0062] Preferably, the flow medium is a cooling medium.

[0063] The flowing medium has a cooling effect, and combined with the rotation of the inner and outer rings 201 and 202, it enhances heat dissipation from the lamp body 101. Furthermore, when the inner and outer rings 201 and 202 are stationary, the flowing medium increases the overall specific heat capacity of the stabilizing assembly 200 and also absorbs heat near the lamp body 101, extending the time it takes for the lamp body 101 to reach its stable operating temperature or overheat protection threshold. This allows the lamp body 101 to operate longer even in conditions where continuous heat dissipation is impossible (such as extremely high ambient temperatures or when the radiator is partially blocked for a short period of time). The cooling medium can be a medium with good cooling properties and good flow properties, such as water, an ethylene glycol aqueous solution, or mineral oil.

[0064] Preferably, heat dissipation fins 109 are provided on the back of the lamp body 101 to enhance the heat dissipation effect of the lamp body 101 .

[0065] When the modular lamp of the present invention is in use, the lamp body 101 is mounted on a carrier via the bracket 100. The sensing module converts the carrier's vibration amplitude into a vibration signal, namely a first parameter, and transmits it to the processor. When the first parameter is less than or equal to a first preset value, indicating that the carrier's current vibration amplitude is relatively small, the processor controls the lamp body 101 to remain stationary and simultaneously controls the output end of the motor 207 to rotate at a relatively low first speed. At this point, the flowing medium is relatively evenly distributed in the first chamber 203 and the second chamber 204. The mass distribution of the inner ring 201 and the outer ring 202 is relatively uniform, the angular momentum is relatively low, and the orientation of the lamp body 101 changes slightly to follow the carrier.

[0066] When the first parameter is greater than the first preset value, it means that the current carrier has a large amplitude of shaking and jolt. The processor controls the lamp body 101 to be in an active state. At the same time, the processor controls the output end of the motor 207 to rotate at a higher second speed, and the centrifugal force generated increases. At this time, the flow medium in the first chamber 203 flows to the second chamber 204 through the connecting chamber 218, so that the mass of the inner ring 201 is reduced, the mass of the outer ring 202 is increased, the angular momentum is increased, and the gyro effect is enhanced. The stabilizing component 200 acts on the lamp body 101 to enable the lamp body 101 to resist the shaking and jolt of the carrier and maintain its original orientation, thereby reducing the impact on the light irradiation range and lighting effect of the lamp body 101.

[0067] Furthermore, the rotation of the inner and outer rings 201, 202 dissipates heat from the lamp body 101, preventing the lamp body 101 from heating up during long-term use, which could lead to a decrease in luminous efficiency and material aging. Combined with the cooling effect of the flowing medium and the heat dissipation fins 109, the heat dissipation efficiency of the lamp body 101 is enhanced. When the inner and outer rings 201, 202 are stationary, the flowing medium increases the overall specific heat capacity of the stabilizing assembly 200 and also absorbs heat near the lamp body 101, extending the time required for the lamp body 101 to reach its stable operating temperature or overheat protection threshold, allowing the lamp body 101 to operate for longer periods of time even when continuous heat dissipation is unavailable.

[0068] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
