[0032] As a technical optimization of this utility model, by setting up a movable plate 12, the movable plate 12 can protect and limit the outer side of the connecting groove 10, so as to prevent the external environment from affecting the use of the 4G temperature and humidity transmitter 3 and the AC / DC constant voltage power supply 5 inside the connecting groove 10, thereby enhancing the safety of use.

The one-way heat-conducting block 16 can prevent the external temperature from being transferred to the protective box 8 through the movable block.

[0041] The working principle and usage process of this utility model: During use:

[0042] The LED street light system has two installation methods for the 4G temperature and humidity transmitter 3. The first method is to install it inside the protective box 8, and the second method is to install it on the light pole. The first method is more expensive and inconvenient to maintain because each light needs to have a 4G temperature and humidity transmitter 3 and an AC / DC constant voltage power supply 5 installed. The second method fixes the 4G temperature and humidity transmitter 3 and the AC / DC constant voltage power supply 5 inside the protective box 8, and fixes the sensor of the 4G temperature and humidity transmitter 3 outside the protective box 8. The entire protective box 8 is fixed on the light pole, eliminating the need to install one set for each light. One set can be installed every other light or every two lights, which reduces the number of units used, lowers the cost, and facilitates maintenance.

[0043] For example:

[0044] Assumptions: A certain section of road in a project requires the installation of LED streetlights (LED 1), which need to adjust their color temperature according to humidity. LED streetlight 1 has an input power of 60W, using 3030 LEDs with two color temperatures: a warm color temperature of 2700K and a cool color temperature of 6500K. Each LED has approximately 6V, and each light panel has 80 LEDs (40 warm and 40 cool). A 60W panel uses two light panels with a total of 160 LEDs (80 warm and 80 cool). The project requires approximately 100 LEDs, 50 on each side of the road, with a distance of approximately 15 meters between the light poles. The second option is used for the 4G temperature and humidity transmitter boxes (3 boxes), installed every two lights at a distance of approximately 45 meters. Assuming humidity is between 40% and 60%, the color temperature of LED streetlight 1 is 4000K; above 65% humidity, the color temperature is 3000K. With humidity below 35%, the color temperature of LED street light body 1 is 5000K. LED street light body 1 starts lighting at 18:00. From 18:00 to 24:00, LED street light body 1 operates at 100% output, with an input power of 60W. After 24:00, the power is reduced to 50%, with an input power of 30W, to reduce electricity consumption and costs. This project uses 0-10V positive logic adjustment.

[0045] Dimming: The LED street light body 1 of this project is expected to light up at 18:00, and will output 100% power at 60W from 18:00 to 24:00. The 4G dual-channel controller 6 receives the dimming strategy transmitted from the cloud platform. After 24:00, it begins to change the output voltage of the Dim1+ and Dim- of the 4G dual-channel controller 6. The Dim1+ and Dim- ports of the dual-color temperature power supply 7 receive the voltage of the Dim1+ and Dim- of the 4G dual-channel controller 6, and begin to change the warm light current V+ and V1- and the cool light current V+ and V2- at the output terminals of the dual-color temperature power supply 7. The current ratio of the two remains unchanged, the total current decreases, the output color temperature remains unchanged, and the power decreases. The specific output voltage values ​​that the 4G dual-channel controller 6Dim1+ and Dim- change depend on the dimming voltage versus output current curve of the dual-color temperature power supply 7. Different manufacturers' dual-color temperature power supplies 7 have different dimming curves, and therefore require different output voltages at the 4G dual-channel controller 6Dim1+ and Dim-. Assuming the dual-color temperature power supply 7's 0-10V dimming curve has an output current of 10% from 0V to 1V, 100% from 9V to 10V, and a linear change from 1V to 9V, theoretically, with a 50% output current from the dual-color temperature power supply 7, the output voltage at the 4G dual-channel controller 6Dim1+ and Dim- would be approximately 4.6V.

[0046] Color temperature adjustment: When the humidity at the installation site is between 40% and 60%, the color temperature of the LED street light body 1 is 4000K. The 4G temperature and humidity transmitter 3 installed in this section of the road collects the humidity at the current installation site and uploads the data every 5 minutes. The cloud platform takes the average value of each uploaded data as the current humidity value. The 4G dual-channel controller 6 receives the color temperature adjustment strategy transmitted from the cloud platform and begins to change the output voltage of the Dim2+ and Dim- ports of the 4G dual-channel controller 6. The Dim2+ and Dim- ports of the dual-color temperature power supply 7 receive the voltage of the Dim2+ and Dim- ports of the 4G dual-channel controller 6 and begin to change the warm light current of the output terminals V+ and V1- and the cool light current of the output terminals V+ and V2-. The total current of the two remains constant, but the ratio of the warm light current to the cool light current is changed, thereby changing the output color temperature. The color temperature adjustment curve of the dual-color temperature power supply 70-10V used in this project is such that when the voltage of the Dim2+ and Dim- ports is 10V, the output terminals V+ and V2- cool light current are at full current output, and the output terminals V+ and V1- warm light current are at 0A. At this time, the color temperature of the LED street light body 1 is 6500K. Conversely, when the voltages at the two ports Dim2+ and Dim- are 0V, the output current at the cold light terminals V+ and V2- is 0A, and the output current at the warm light terminals V+ and V1- is full. At this time, the color temperature of the LED street light body 1 is 2700K.

[0047] Other 0-10V linear changes. Theoretically, when the color temperature of the LED street light body 1 is 4000K, the output voltage at the 4G dual-channel controller 6Dim2+, Dim- is approximately 4.4V.

[0048] When the humidity in the area where the LED street light body 1 is installed changes, such as during rain or fog, the humidity gradually increases. When the humidity is still in the range of 60%-65%, the color temperature of the LED street light body 1 remains unchanged at 4000K. Only when the cloud platform detects that the average humidity of the 4G temperature and humidity transmitter 3 exceeds 65% three times in a row, that is, after 15 minutes, will the cloud platform issue a command to the 4G dual-channel controller 6. The 4G dual-channel controller 6 changes the output voltage of the Dim2+ and Dim- groups. Theoretically, when the color temperature of the LED street light body 1 is 3000K, the output voltage of the 4G dual-channel controller 6 at the Dim2+ and Dim- terminals is about 1.5V. The Dim2+ and Dim- ports of the dual-color temperature power supply 7 receive the voltages from the Dim2+ and Dim- ports of the 4G dual-channel controller 6, and begin to change the warm light current (V+, V1-) and the cool light current (V+, V2-) at the output terminals of the dual-color temperature power supply 7. The sum of the two currents remains constant, and the ratio of the warm light current to the cool light current is adjusted according to the Dim2+ and Dim- voltages. When the humidity in the area where the LED street light body 1 is installed gradually decreases, the color temperature of the LED street light body 1 remains at 5000K within the humidity range of 60%-65%. Only when the humidity drops below 60%, and the cloud platform detects three consecutive times that the average humidity of the 4G temperature and humidity transmitter 3 is below 60%, that is, after 15 minutes, does the cloud platform send a command to the 4G dual-channel controller 6. The 4G dual-channel controller 6 then changes the output voltage of the Dim2+ and Dim- ports, thereby changing the warm light and cool light currents of the dual-color temperature power supply 7, and the color temperature becomes 4000K. The 60%-65% humidity range serves as a buffer zone. This setting aims to prevent the LED street light body 1 from fluctuating between two color temperature thresholds due to humidity, thus avoiding impacting the lighting effect. Similarly, when the humidity decreases from the 40%-60% range to below 35%, the color temperature of the LED street light body 1 will change from 4000K to 5000K. The working principle is the same as above, except that the output voltage at both ends of the 4G dual-channel controller 6Dim2+ and Dim- is approximately 6.6V. Conversely, when the humidity gradually increases from below 35% to the 40%-60% range, the color temperature of the LED street light body 1 will change from 5000K to 4000K.

[0049] In summary: This LED street light control system, which allows for remote adjustment of color temperature based on humidity, solves the problem of… (structure).
