Technical Field
[0001] This utility model relates to the field of lighting system technology, and more specifically, to a lighting system for an artificial ski resort. Background Technology
[0002] As a new type of winter sports facility, artificial ski resorts provide skiers with a winter sports experience that is not limited by the seasons through advanced refrigeration and snowmaking technologies. Most existing artificial ski resorts are located indoors to ensure a year-round, authentic ski resort environment. The internal temperature of the ski resort is usually maintained at an extremely low level, which places extremely high demands on the durability of the equipment, especially the lighting system.
[0003] In extremely cold conditions, the electronic components of lighting fixtures are highly susceptible to temperature fluctuations, leading to performance degradation or even damage. This is particularly true in artificial ski resorts that emphasize the enjoyment of skiing. These resorts employ various lighting techniques, such as color changes, brightness adjustments, and dynamic transformations, to enhance the fun and visual appeal of skiing. However, these color changes, brightness adjustments, and dynamic transformations are often accompanied by rapid power fluctuations. When the lights are dimmed, their power decreases. During this process, due to the low temperature of the artificial ski resort itself, the internal temperature of the lighting fixtures is difficult to maintain and drops rapidly with the external low temperature. When the lights are brightened again, the increased power causes the internal temperature of the fixtures to rise rapidly, but due to the influence of the external low temperature environment, this temperature change becomes extremely drastic. These frequent temperature fluctuations subject the electronic components inside the lighting fixtures to significant thermal stress, leading to performance degradation and shortened lifespan. This not only reduces the durability of the lighting fixtures but also increases maintenance costs and potential safety risks.
[0004] Therefore, in low-temperature environments, the internal temperature of the lighting system fluctuates rapidly during brightness adjustment or other operations, which is of great significance for protecting the lighting fixtures and extending their service life. Utility Model Content
[0005] The purpose of this application is to provide a lighting system for an artificial ski resort, which solves the technical problem that the rapid fluctuation of the internal temperature of the lamps during brightness adjustment or other operations in low-temperature environments reduces the lifespan of the lamps, thus ensuring the stability and durability of the lighting system.

[0009] The heating and heat preservation circuit receives signals transmitted by the lighting control circuit.
[0010] The heating and heat preservation circuit includes a start-up circuit, a monitoring circuit, and a heating circuit. The start-up circuit is connected to the lighting control circuit and the monitoring circuit, respectively. The monitoring circuit is connected to the heating circuit.
[0011] The startup circuit is used to start the monitoring circuit;
[0012] The monitoring circuit monitors the temperature of the area where the lighting lamp is located based on the signal transmitted by the lighting lamp control circuit, and outputs a control signal to the heating circuit.
[0013] The heating circuit includes a heating element, which heats up and maintains its temperature according to the control signal transmitted by the monitoring circuit; the heating element is arranged around the lighting control circuit.
[0014] In some embodiments, the heating circuit includes a heating element and a second transistor. The emitter of the second transistor is connected to a power source through the heating element, the collector of the second transistor is grounded, and the base of the second transistor is connected to the monitoring circuit.
[0015] In some embodiments, the heating circuit further includes a thermistor, and the emitter of the second transistor is connected to the heating element through the thermistor.
[0016] In some embodiments, the heating element is a heating resistance wire.
[0017] In some embodiments, the start-up circuit includes an OR gate, one input of which is connected to the lighting control circuit, and the other two inputs of the OR gate, the output of the OR gate, and the monitoring circuit are connected together.
[0018] In some embodiments, the monitoring circuit includes a first transistor, a thermistor, and a plurality of resistors. The collector of the first transistor is connected to a power supply through a resistor, and the collector of the first transistor is connected to the heating circuit through a resistor. The emitter of the first transistor is grounded through the thermistor. The base of the first transistor is connected to the start-up circuit through a resistor, and the base of the first transistor is grounded through a resistor.
[0019] In some embodiments, the thermistor is model TMP6131DECR.
[0020] In some embodiments, the lighting control circuit includes a third transistor, a diode, and multiple resistors. The base of the third transistor is connected to the controller through a resistor, and the base of the third transistor is grounded through the diode. The collector of the third transistor is connected to a power supply through a second resistor, and the collector of the third transistor is also connected to multiple lighting lamps.

[0022] The technical solution of this application has at least the following advantages and beneficial effects:
[0023] 1. This utility model includes a controller and multiple light groups, each light group comprising a heating and insulation circuit, a lighting control circuit, and multiple lights. When the controller first transmits a signal to the lighting control circuit to turn on the lights, the heating and insulation circuit simultaneously receives the signal and automatically starts. Once started, the heating element of the heating and insulation circuit heats up until the internal temperature reaches a preset threshold, then enters a heat preservation state. The heating element is located around the lighting control circuit, stabilizing the ambient temperature around the lighting control circuit. Even if the lights are subsequently turned off or dimmed, the internal temperature of the lamp remains stable. When the lights are turned on or brightened again, the internal temperature of the lamp will not change significantly, thus avoiding damage to the lamp caused by excessive temperature differences. This design effectively solves the problem of shortened lamp life caused by rapid fluctuations in the internal temperature of the lamp during brightness adjustment or other operations in low-temperature environments, significantly improving the stability and durability of the lighting system.
[0024] 2. In artificial ski resorts, existing lighting systems typically maintain the operating temperature of the lights by using insulation layers. However, insulation alone cannot completely prevent components from being damaged by excessively low temperatures in extreme environments. In contrast, heating and insulation circuits can dynamically adjust the heating power based on the internal temperature of the lights using temperature sensors and feedback mechanisms, thus avoiding temperature fluctuations. This dynamic adjustment function is something that insulation layers cannot achieve, especially during frequent adjustments to light brightness. When the light dims, the temperature drops, and the insulation layer cannot actively replenish heat. Heating and insulation circuits, on the other hand, can replenish heat to maintain the operating temperature of the lights, preventing damage caused by excessive temperature differences. Therefore, heating and insulation circuits are superior in maintaining stable internal temperatures of lights, effectively protecting light components and extending their lifespan.

[0034] Please refer to Figures 1-3 This utility model provides a lighting system for an artificial ski resort, which is the same as the prior art, including a controller and multiple sets of lights, and the controller and multiple sets of lights are connected together; the staff can start or stop the lights through the controller.
[0035] It should be noted that the controller includes a main control chip, the model of which is STM32F103C8T6;
[0036] It should be noted that the controller outputs PWM signals to the lighting group through the IO port for adjusting the brightness of the lights.
[0037] Unlike existing technologies, the lighting assembly includes multiple lighting lamps 1, a heating and heat preservation circuit, and a lighting control circuit. The lighting control circuit is connected to the multiple lighting lamps 1, and is also connected to the controller and the heating and heat preservation circuit.
[0038] The lighting control circuit starts or stops lighting lamp 1 or adjusts the brightness of lighting lamp 1, and at the same time outputs a second control command to the heating and heat preservation circuit;
[0039] The heating and heat preservation circuit receives signals transmitted from the lighting control circuit.
[0040] The heating and heat preservation circuit includes a starting circuit, a monitoring circuit, and a heating circuit. The starting circuit is connected to both the lighting control circuit and the monitoring circuit; the monitoring circuit is connected to the heating circuit.
[0041] Start-up circuit, used to start the monitoring circuit;

[0044] Specifically, the starting circuit includes an OR gate, one input of which is connected to the lighting control circuit, and the two inputs of the OR gate, the output of the OR gate, and the monitoring circuit are connected together.
[0045] Specifically, the monitoring circuit includes a first transistor, a thermistor, and multiple resistors. The collector of the first transistor is connected to the power supply through a resistor, and the collector of the first transistor is connected to the heating circuit through a resistor. The emitter of the first transistor is grounded through the thermistor. The base of the first transistor is connected to the start-up circuit through a resistor, and the base of the first transistor is grounded through a resistor.
[0046] It should be explained that the thermistor in the monitoring circuit is used to monitor the ambient temperature of the area where the lighting lamp 1 is located;
[0047] Specifically, the heating circuit includes a heating element and a second transistor. The emitter of the second transistor is connected to the power supply through the heating element, the collector of the second transistor is grounded, and the base of the second transistor is connected to the monitoring circuit.
[0048] In this embodiment, the heating element is a heating resistance wire 2.
[0049] In this embodiment, the heating circuit also includes a thermistor, and the emitter of the second transistor is connected to the heating element through the thermistor.
[0050] It should be explained that the thermistor in the heating circuit is used for overheat protection to prevent the heating element from working continuously and causing the lamp temperature to become too high, which would damage the lamp's lifespan.
[0051] It should be noted that the thermistor in the monitoring circuit and the thermistor in the heating circuit are both model TMP6131DECR.
[0052] Furthermore, the heating and heat preservation circuit includes an OR gate U1, a heating element U2, thermistors U3 and U4, transistors Q1 and Q2, and resistors R1, R2, R3, R4, and R5; wherein, the starting circuit includes an OR gate U1; the monitoring circuit includes a thermistor U4, resistors R1, R2, R4, and R5, and transistor Q1; and the heating circuit includes a heating element U2, resistor R3, thermistor U3, and transistor Q2.
[0053] It should be noted that the first transistor is transistor Q1, the second transistor is transistor Q2, and the third transistor is transistor Q3;
[0054] Specifically, such as Figure 2 As shown, pin 1 of OR gate U1 is set as the CON_IN input terminal; pins 2 and 4 of OR gate U1 are connected to one end of resistor R1; pin 3 of OR gate U1 is grounded; pin 5 is connected to the power supply; the other end of resistor R1, one end of resistor R2, and the base of transistor Q1 are connected; the collector of transistor Q1, one end of resistor R5, and one end of resistor R4 are connected; the other end of resistor R4, one end of resistor R3, and one end of heating resistance wire U2 are connected to the power supply; the other end of resistor R3, one end of thermistor U3, and the other end of heating resistance wire U2 are connected; the other end of thermistor U3 is connected to the emitter of transistor Q2; the base of transistor Q2 is connected to one end of resistor R5; the collector of transistor Q2, one end of thermistor U4, and the other end of resistor R2 are connected and grounded.
[0055] It should be noted that the CON_IN input terminal is connected to the lighting control circuit; transistor Q1 is NPN type and transistor Q2 is PNP type.
[0056] To facilitate understanding, the working process of the heat preservation control circuit is explained below:
[0057] When the CON_IN input terminal, i.e., pin 1 of OR gate U1, receives the signal transmitted by the lighting control circuit, pin 4 of OR gate U1 outputs a high level. At this time, pin 2 of OR gate U1 receives a high level, and the base of transistor Q1 receives a high level through resistor R1 and is turned on.
[0058] If thermistor U4 monitors temperature changes, its resistance increases with temperature. If thermistor U4 detects a low temperature, its resistance decreases. At this time, the base of transistor Q2 receives a low level, causing transistor Q2 to conduct and heating element U2 to start heating. Thermistor U3 monitors temperature changes in real time; its resistance increases with temperature. At this time, the voltage across heating element U2 decreases, preventing overheating.
[0059] If thermistor U4 detects that the temperature is too high, the resistance of thermistor U4 increases. At this time, the base of transistor Q2 receives a high level, so transistor Q2 is cut off, and heating element U2 stops heating until thermistor U4 detects that the temperature has dropped.
[0060] The lighting control circuit includes a third transistor, a diode, and multiple resistors. The base of the third transistor is connected to the controller through a resistor, and the base of the third transistor is grounded through a diode. The collector of the third transistor is connected to the power supply through a second resistor, and the collector of the third transistor is also connected to multiple lighting lamps. The emitter of the third transistor is grounded through a resistor, and the emitter of the third transistor is also connected to the heating circuit.
[0061] Furthermore, taking two lighting lamps 1 connected to the lighting control circuit as an example, the lighting control circuit includes transistor Q3, resistors R6, R7, and R8, diode D1, and lighting lamps LED1 and LED2;
[0062] It should be noted that the third transistor is transistor Q3;
[0063] Specifically, such as Figure 3 As shown, the anode of LED1, the anode of LED2, and one end of resistor R6 are connected to a power source. The other end of resistor R6, the cathode of LED1, the cathode of LED2, and the collector of transistor Q3 are connected. The base of transistor Q3, one end of resistor R7, and the anode of diode D1 are connected. The cathode of diode D2 is connected to one end of resistor R8. The other end of resistor R8 is connected to the emitter of transistor Q3, and this is where the OUT output terminal is set. The other end of resistor R7 is set as the IN input terminal.
[0064] It should be noted that transistor Q3 is an NPN type;
[0065] It should be noted that the IN input terminal is connected to the I / O port of the main control chip, and the I / O port transmits PWM signals to the lighting control circuit to start lighting lamp 1 or adjust the brightness of lighting lamp 1; the OUT output terminal is connected to the CON_IN input terminal;
[0066] The working process when two lights 1 are connected to the lighting control circuit is explained below:
[0067] After the IN input terminal of the lighting control circuit receives the PWM signal from the main control chip, transistor Q3 turns on, and lighting LED1 and lighting LED2 light up. The OUT output terminal outputs a signal to the CON_IN input terminal.
[0068] It should be noted that since the controller transmits a PWM signal, the signal output by the lighting control circuit is also a PWM signal. To prevent damage to the electronic components in the heating and heat preservation circuit caused by frequent switching of the PWM signal, a start-up circuit is provided in the heating and heat preservation circuit of this invention. When the start-up circuit reads the PWM signal for the first time, it converts the PWM signal into a high-level signal, thereby ensuring that the monitoring circuit and the heating circuit continue to work. This allows the internal temperature of the lamp to remain stable for a long time after it is turned off. In cold environments such as artificial ski resorts, when the lamp is turned off and idle for a long time, it can be restarted without being damaged by the low external temperature, thus ensuring the safe start-up and normal use of the lamp.
[0069] It needs to be explained that the lighting control circuit controls multiple lighting lamps 1, and the heating resistance wire 2, as a heating element, is placed around the lighting control circuit, such as... Figure 4 , Figure 5 As shown. In this way, the heating resistance wire can directly provide a stable temperature environment for the lighting control circuit and the multiple lights it controls, thereby maintaining the normal operation of the entire lighting system under low-temperature conditions;
[0070] It should be noted that this utility model also includes a power supply module, which is existing technology and will not be described in detail here;
[0071] It should be noted that all of the above-mentioned electronic components are available for purchase on domestic and international markets.
[0072] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description.
