Description

Technical Field

[0001] The utility model relates to the field of ice and snow landscape lighting devices, in particular to a light driver for ice and snow landscapes. Background Art

[0002] Snow and ice landscapes typically combine ice sculptures with corresponding lighting. Illuminated by different colored lights, the ice sculptures create distinct effects, further enhancing the overall landscape. Since the ambient temperature of snow and ice landscapes often ranges from -20°C to -40°C, only at this temperature can the ice sculptures remain intact. Existing lighting solutions often use LED light strips, which typically need to emit light in different colors and are therefore typically controlled by a single light driver. The normal operating temperature of typical light drivers ranges from room temperature to around 40 to 50°C above zero. Drivers used in snow and ice landscapes, however, typically require thermal insulation because the ambient temperature is much lower than the driver's normal operating temperature. A common approach is to add an insulation layer to the driver's exterior. However, since the driver itself continuously releases heat during operation, the temperature of the driver's exterior rapidly rises due to the insulation layer, easily exceeding the ambient temperature required for normal operation. Therefore, maintaining a relatively suitable operating temperature for the light driver in low ambient temperatures remains a challenge. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a light driver for ice and snow landscapes.

[0004] The utility model adopts the following technical solution: a light driver for ice and snow landscape, including a main body and a heat preservation and heat dissipation component arranged on the periphery of the main body, the heat preservation and heat dissipation component includes a heat preservation part and a heat dissipation part, the heat preservation part is arranged on the outer wall of the main body, the heat dissipation part is arranged outside the heat preservation part and the end of the heat dissipation part passes through the heat preservation part and is placed between the heat preservation part and the outer wall of the main body.

[0005] The heat dissipation part includes a heat dissipation contact, a heat dissipation fin and an elastic member. One end of the heat dissipation contact passes through the insulation part and contacts the main body, the other end of the heat dissipation contact contacts the heat dissipation fin and the elastic member is arranged between the heat dissipation contact and the heat dissipation fin. When the temperature of the main body is higher than the normal operating temperature, the heat dissipation contact conducts heat to the elastic member, and the elastic member deforms to push the heat dissipation fin to contact external ice and snow.

[0006] The heat dissipation contact includes a first telescopic contact and a second telescopic contact, one end of the first telescopic contact abuts against the outer wall of the body, the first telescopic contact extends outward through the heat insulation portion, the second telescopic contact is inserted into the first telescopic contact, and one end of the second telescopic contact is placed outside the first telescopic contact and is connected to the heat dissipation fin. The elastic member is provided between the first telescopic contact and the second telescopic contact, and the ends of the elastic member are respectively connected to the first telescopic contact and the second telescopic contact.

[0007] The elastic member includes a shape memory spring, one end of the shape memory spring is fixed on the first telescopic contact, and the other end of the shape memory spring is fixed on the second telescopic contact. When the first telescopic contact transfers heat to the shape memory spring, the shape memory spring deforms and drives the second telescopic contact to extend, pushing the heat dissipation fins to contact external ice and snow.

[0008] The heat-insulating portion includes a heat-insulating felt, which is wrapped around and fixed to the outer wall of the body. A through-hole is provided on the heat-insulating felt for the first telescopic contact to pass through, and the first telescopic contact passes through the through-hole and is fixed to the heat-dissipating fin.

[0009] The thermal insulation felt is provided with an accommodating groove for accommodating the heat dissipating fins. The heat dissipating fins include a base plate and a plurality of heat dissipating fins fixed on the end surface of the base plate. The plurality of heat dissipating fins are perpendicular to the base plate and adjacent heat dissipating fins are parallel to each other. The accommodating groove is opposite to an end of the base plate facing away from the heat dissipating fins. When the second telescopic contact moves toward the direction of the first telescopic contact, the base plate is placed in the accommodating groove.

[0010] Compared with the existing technology, the utility model first wraps the main body with an insulating felt made of insulating material, so that the heat dissipation of the main body is reduced. At the same time, when the heat accumulation causes the temperature to exceed the appropriate temperature, the shape memory alloy is affected by the high temperature conducted by the first telescopic contact and stretches, pushing the heat dissipation fins to move, and finally the heat dissipation fins abut against the external ice and snow environment to dissipate heat. When the temperature drops, the memory alloy spring retracts again, causing the first telescopic contact to leave the outer wall of the main body, that is, the first telescopic contact basically does not conduct the heat of the main body, and then the temperature between the main body and the insulating felt can be made to rise again. This reciprocating process can maintain the working temperature of the main body within a reasonable range. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] Reference Figure 1-2 A light driver for ice and snow landscapes comprises a main body 1 and a heat-insulating and heat-dissipating assembly disposed on the periphery of the main body 1. The heat-insulating and heat-dissipating assembly comprises a heat-insulating portion and a heat-dissipating portion 3. The heat-insulating portion is disposed on the outer wall of the main body 1, and the heat-dissipating portion 3 is disposed outside the heat-insulating portion, with the end of the heat-dissipating portion 3 extending through the heat-insulating portion and positioned between the heat-insulating portion and the outer wall of the main body 1. In this application, the main body 1 can be a conventional light driver, such as the light driver disclosed in Utility Model Patent Publication No. "CN220606129U," or any other conventional light driver. The heat-insulating and heat-dissipating portions 3 are simply added to the exterior of an existing driver. The heat-insulating and heat-dissipating portions 3 merely exchange heat with the existing driver's outer casing. Their specific function is that, due to the heat-insulating effect of the heat-insulating portion and the heat dissipated by the light driver during use, the temperature within the area enclosed by the heat-insulating portion gradually rises, eventually exceeding the temperature limit for normal operation (temperature overrun). When the temperature exceeds the limit, the heat-dissipating portion 3 activates to reduce the temperature to a suitable level.

[0016] In the present application, the heat dissipation portion 3 includes a heat dissipation contact, a heat dissipation fin 34, and an elastic member. One end of the heat dissipation contact passes through the insulation portion and contacts the body 1, while the other end of the heat dissipation contact contacts the heat dissipation fin 34. The elastic member is disposed between the heat dissipation contact and the heat dissipation fin 34. When the temperature of the body 1 is higher than the normal operating temperature, the heat dissipation contact conducts heat to the elastic member, causing the elastic member to deform and push the heat dissipation fin 34 into contact with external ice and snow. The heat dissipation contact includes a first telescopic contact and a second telescopic contact. One end of the first telescopic contact abuts against the outer wall of the body 1. The first telescopic contact extends outward through the insulation portion, while the second telescopic contact is inserted into the first telescopic contact. The second telescopic contact, with one end outside the first telescopic contact, connects to the heat dissipation fin 34. The elastic member is disposed between the first and second telescopic contacts, with the ends of the elastic member correspondingly connected to the first and second telescopic contacts. The elastic element includes a shape memory spring 33, made of a shape memory alloy. Its initial state is the normal operating temperature of the light driver. When the temperature rises above the initial state, the shape memory spring 33 expands. One end of the shape memory spring 33 is fixed to the first telescopic contact, and the other end is fixed to the second telescopic contact. When the first telescopic contact transfers heat to the shape memory spring 33, the shape memory spring 33 deforms, causing the second telescopic contact to extend, pushing the heat sink 34 into contact with external ice and snow. Simultaneously, the expansion of the shape memory spring 33 pushes the first telescopic contact into contact with the outer shell of the main body 1, allowing heat dissipated by the main body 1 to be transferred through the first telescopic contact to the shape memory spring 33. The temperature of the outer shell serves as the trigger for the deformation of the shape memory spring 33. When the temperature returns to a normal range, the shape memory spring 33 returns to its initial state. At this point, the length of the shape memory spring 33 decreases, driving the first and second telescopic contacts to retract. The first telescopic contact detaches from the outer wall of the body 1 and no longer contacts the body 1. Simultaneously, the heat dissipation fins 34 driven by the second telescopic contact also detach from external ice and snow. This slows down the heat exchange between the body 1 and the outside world, allowing the body 1 to enter a temperature-maintaining state.

[0017] The insulation part includes an insulation felt 2, which is wrapped around the outer wall of the body 1 and fixed. A through hole is provided on the insulation felt 2 for the first telescopic contact to pass through. The first telescopic contact passes through the through hole and is fixed to the heat dissipation fin 34.

[0018] The insulation felt 2 can be provided with a receiving groove for accommodating the heat sink 34. The heat sink 34 comprises a base plate 342 and a plurality of heat sink fins 341 fixed to the end surface of the base plate 342. The heat sink fins 341 are perpendicular to the base plate 342, and adjacent heat sink fins 341 are parallel to each other. The receiving groove is opposite the end of the base plate 342 facing away from the heat sink 341. When the second telescopic contact moves toward the first telescopic contact, the base plate 342 is placed in the receiving groove. When the heat sink 34 driven by the second telescopic contact is freed from external ice and snow, the base plate 342 of the heat sink 34 is placed in the receiving groove, thereby reducing the overall volume and making it more convenient to use.

[0019] Compared with the prior art, the present invention first wraps the main body 1 with an insulating felt 2 made of insulating material, so that the heat dissipation of the main body 1 is reduced. At the same time, when the heat accumulation causes the temperature to exceed the appropriate temperature, the shape memory alloy is affected by the high temperature conducted by the first telescopic contact and stretches, pushing the heat dissipation fins 34 to move, and finally the heat dissipation fins 34 abut against the external ice and snow environment to dissipate heat. When the temperature drops, the memory alloy spring retracts again, causing the first telescopic contact to leave the outer wall of the main body 1, that is, the first telescopic contact basically does not conduct the heat of the main body 1, and then the temperature between the main body 1 and the insulating felt 2 can be made to rise again. This reciprocating process can maintain the operating temperature of the main body 1 within a reasonable range.

[0020] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
