Description
Technical field
The utility model relates to the temperature protection system of LED outdoor scene lamp, particularly LED outdoor scene lamp.
Background technology
Because the LED lamp is the meeting evolution of heat own when illumination; Cause the too high circuit control panel that burns out of temperature; The way of existing reduction lamp panel temperature mainly contains two kinds: cooling fan is installed on the shell of casing or temporarily reduces the power of LED lamp; If use fan for cooling just to need bigger rotation speed of the fan separately, rotation speed of the fan is too high then can to produce noise, and utilizes the way that reduces LED lamp power to reduce the illuminating effect that temperature can influence the LED lamp separately.
Summary of the invention
The purpose of the utility model provides a kind of LED outdoor scene light temperature protection system, and this temperature protection system cools and good illumination effect can in time reduce the temperature of IC.
For achieving the above object, LED outdoor scene light temperature protection system comprises IC working plate and LED lamp, and the IC working plate is provided with IC; The IC working plate is provided with temperature sensor; Side at the IC working plate is equipped with cooling fan; Be connected with A/D converter on the temperature sensor, A/D converter is connected with control chip, and control chip is controlled the work of cooling fan and led to the curtage on the LED lamp.
Utilize the control method of said temperature protection system to be: at first, three or three above preset temperature value to be set in control chip; Every at a distance from one section fixing time for reading, the value of A/D converter reading temperature sensor, the temperature value that control chip relatively reads and the temperature value of setting; When the temperature value that reads during less than minimum value, control chip control cooling fan is in closed condition; When the temperature value that reads between preset minimum temperature value and the preset interim temperature value time, control chip control cooling fan carries out low-speed running, LED lamp power maintenance ratings; Medium temperature section different can change speed of cooling fan; When the temperature value that reads during greater than preset maximum temperature values; Control chip control cooling fan rotation speed is high speed; The reduction step by step of the LED of control chip control simultaneously lamp power, behind a LED lamp of the every reduction power, temperature value that control chip relatively reads and maximum temperature value; When the temperature value that reads greater than maximum temperature value, then continue to reduce step by step LED lamp power, the cooling fan rotation speed of control chip control simultaneously is high speed; When the temperature value that reads equals maximum temperature value, then keep LED lamp power constant, control chip control cooling fan rotation speed is high speed; When the temperature value that reads less than maximum temperature value, the LED lamp power that then slowly raises step by step, control chip control cooling fan rotation speed be high speed; A LED lamp of every rising power, temperature value that control chip relatively reads and maximum temperature value; After the power of LED lamp returned to ratings, the temperature value that reads was still less than maximum temperature value, again with speed of cooling fan from reducing the most step by step.Like this, not only cooling is effective, and illuminating effect can not be affected yet, and can in time reduce the temperature of IC.
As improvement, described IC working plate separates setting with the LED lamp.Like this, IC working plate and LED lamp can carry out independent heat radiation, therefore, and good heat dissipation effect.
As specializing; Control chip comprises signal receiving module, signal processing module, comparative device, cooling fan controller and LED lamp controller; The signal that signal receiving module will receive from A/D converter is transferred to signal processing module and handles; Treated signal compares with preset definite value in comparative device, comparative device with the comparison result transmission in cooling fan controller and LED lamp controller.
