Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and in particular to a wide voltage powered LED lamp control module and an energy saving method thereof. Background Art

[0002] LED lamps are solid-state semiconductor devices that can convert electrical energy into visible light. They can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.

[0003] For example, an airport navigation light LED lamp control module that is easy to install and has an application number of CN202121857749.X and an authorization announcement date of 2023.01.13 includes a control module body, an installation mechanism and a release mechanism. A fixing plate is fixedly connected to the side wall of the control module body, and a through hole is opened on the side wall of the fixing plate. A fixing frame is fixedly connected to the side wall of the control module body. The utility model uses a first clamping block to pre-fix the control module body on the mounting hole of the cabinet mounting plate, and then drives the extrusion frame to clamp and fix the control module body on the mounting plate of the cabinet through screws, which is convenient for a single staff member to operate and avoids the situation where the screws cannot be fixed due to the control module body being too heavy. The utility model uses a second clamping block and a clamping plate to keep the nut and the extrusion frame away from the first clamping block, so that the first clamping block is convenient for clamping on the mounting hole of the cabinet mounting plate, thereby pre-fixing the control module body and improving the installation efficiency of the control module body.

[0004] The above-mentioned LED lamp control modules and those in the prior art are mostly relatively simple and cannot calculate the risks of LED lamps during operation. As a result, when the risk of LED lamps being damaged is high, the LED lamp control module cannot quickly control the LED lamps, which greatly increases the probability of LED lamps being damaged. At the same time, most existing LED lamps are powered by photovoltaic power generation + grid power supply, which results in poor stability of the LED lamps during operation, resulting in high energy consumption of the LED lamps. Therefore, it is urgent to design a wide voltage powered LED lamp control module and its energy-saving method to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide an LED lamp control module with a wide voltage supply and an energy-saving method thereof, so as to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

If D>1, the LED lamp will be overloaded and the power supply of the LED lamp needs to be adjusted. If D=1, the LED lamp runs in the optimal state.

[0012] The factor analysis module performs risk calculation on the data collected by the information collection unit through a risk calculation formula, and the risk calculation formula is as follows:

[0013] S=R×C

[0014] Among them, R is the risk rate of the LED lamp suffering from common adverse effects and occurring risks, and C is the severity rate of the LED lamp occurring risks. If 0 < S ≤ 0.4, the operating risk of the LED lamp is relatively low, and there is no need to adjust the operation of the LED lamp. If 1 ≥ S > 0.4, the operating risk of the LED lamp is relatively high, and it is necessary to adjust the operation of the LED lamp.

[0015] Furthermore, the calculation control unit is used to calculate the data analyzed by the data analysis unit. The calculation control unit is also used to control the operation of the LED lamp according to the calculation result. The calculation control unit includes a calculation module and a control module. The calculation module calculates the data analyzed by the data analysis unit through a calculation formula.
