The embodiment of the invention also 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 of the lamp body 101.
The axes of the inner ring 201 and the outer ring 202 may be perpendicular to the back of the lamp body 101, or may have a certain inclination angle. The inner ring 201 and the outer ring 202 drive the plurality of connecting pieces 217 to rotate, and the connecting pieces 217 have the function of fan blades so as to generate blowing force or suction force on the lamp body 101 to dissipate heat, thereby avoiding the decrease of luminous efficiency and ageing of materials caused by the increase of the temperature of the lamp body 101 during long-term use. In addition, the outer profile of the connector 217 may be configured in a fan blade shape to better create a blowing or suction force.
Of course, fan blades may be disposed on the end surface of the inner ring 201 or the outer ring 202 near the lamp body 101, or grooves may be disposed on the end surface of the inner ring 201 or the outer ring 202 at equal intervals along the circumferential direction of the inner ring 201 or the outer ring 202, and when the inner ring 201 or the outer ring 202 rotates, blowing force is generated on the back of the lamp body 101 by the fan blades or the grooves to dissipate heat.
Preferably, the flowing medium is a cooling medium.
The flowing medium has a cooling effect, and combines the rotation of the inner ring 201 and the outer ring 202 to promote the heat dissipation effect on the lamp body 101. In addition, when the inner ring 201 and the outer ring 202 are stationary, the flowing medium increases the specific heat capacity of the whole stabilizing assembly 200, and can also play a role in absorbing heat near the lamp body 101, so that the time required for the lamp body 101 to reach the stable working temperature or the overheat protection threshold value is prolonged, and the lamp body 101 can be allowed to work for a longer time under the condition that continuous heat dissipation is impossible (for example, the environment temperature is extremely high or the radiator is partially shielded in a short time). The cooling medium can be water, glycol aqueous solution or mineral oil, etc. with good flow property.
Preferably, the back of the lamp body 101 is provided with a heat dissipation fin 109 to enhance the heat dissipation effect on the lamp body 101.
When the combined lamp is used, the lamp body 101 is arranged on a carrier through the bracket 100, and the sensing module converts the shaking amplitude of the acquired carrier into a shaking signal, namely a first parameter, and sends the shaking signal to the processor. When the first parameter is smaller than or equal to the first preset value, it indicates that the jolt and shake amplitude of the current carrier is smaller, the processor controls the lamp body 101 to be in a static state, meanwhile, the processor controls the output end of the motor 207 to rotate at a lower first speed, at this time, the flowing medium is uniformly 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 uniform, the angular momentum is smaller, and the orientation of the lamp body 101 is slightly changed along with the carrier.
When the first parameter is greater than the first preset value, it indicates that the current carrier jolt and shake amplitude is greater, the processor controls the lamp body 101 to be in an active state, and simultaneously, the processor controls the output end of the motor 207 to rotate at a higher second speed, so that the generated centrifugal force increases, at this time, the flowing 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, the gyroscopic effect is enhanced, and the stabilizing component 200 acts on the lamp body 101, so that the lamp body 101 resists jolt and shake of the carrier and keeps the original orientation, thereby reducing the influence on the light irradiation range and the illumination effect of the lamp body 101.
In addition, the inner ring 201 and the outer ring 202 rotate to radiate heat of the lamp body 101, so that the problem that the temperature of the lamp body 101 is increased during long-term use, the luminous efficiency is reduced, the material is aged, and the heat radiation effect of the lamp body 101 is improved by combining the cooling effect of the flowing medium and the heat radiation fins 109. When the inner ring 201 and the outer ring 202 are stationary, the flowing medium increases the specific heat capacity of the whole stabilizing assembly 200, and can also play a role in absorbing heat near the lamp body 101, so that the time required for the lamp body 101 to reach the stable working temperature or the overheat protection threshold value is prolonged, and the lamp body 101 can be allowed to work for a longer time under the condition that heat cannot be continuously dissipated.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the present invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
