Abstract
The utility model discloses a radiation control system for a stage used LED spotlight. A brightness signal output end of a central processing unit (CPU) of the system is connected with the LED lamp; a fan rotation speed signal output end of the CPU is connected with a fan; a temperature signal input end of the CPU is connected with a temperature sensor; and a highest rotation speed setting module for each gear of the radiating fan is connected with the CPU. With the system, the noise of the field can be controlled while the temperature of the LED lamp is reduced.
Description
Technical field
The utility model relates to the light of stage technical field, is specifically related to a kind of stage with LED spotlight cooling control system.
Technical background
At present; Known great power LED (Light Emitting Diode; Light-emitting diode) light fixture generally adopts radiator fan to carry out forced heat radiation; And two states is also only opened and close to the control model of this radiator fan, can not regulate the rotating speed of radiator fan according to the heating situation of LED light fixture, strengthened energy consumption.Particularly can't select the maximum (top) speed of radiator fan according to the scene to the demand of noise control the local user who noise is had strict demand.Can produce serious noise pollution like this.
The utility model content
The purpose of the utility model is to above-mentioned technical problem, provides a kind of stage with LED spotlight cooling control system, and this cooling control system can be when giving the cooling of LED light fixture, the noise that control is on-the-spot.
For realizing this purpose; The stage that the utility model designed comprises radiator fan and LED light fixture module with LED spotlight cooling control system, it is characterized in that: it also comprises CPU (Central Processing Unit; Central processing unit), each gear maximum speed of temperature sensor and radiator fan is provided with module; Wherein, the luminance signal output of CPU connects LED light fixture module, and the fan rotating speed signals output of CPU connects radiator fan; The temperature signal input of CPU connects the signal output part of temperature sensor, and each gear maximum speed of radiator fan is provided with the signal input part of the signal output part connection CPU of module.
The VT of said CPU is connected with display.
The signal input part of said CPU is connected with input keyboard.
In the technique scheme, it also comprises the radiator that is arranged on the LED light fixture module, and said radiator connects temperature sensor.
The utility model module through CPU, temperature sensor, each gear maximum speed of radiator fan are set; Realized that the radiator fan maximum (top) speed that is provided with in advance according to the user limits and the heating situation of LED light fixture module; The rotating speed of radiator fan and the current brightness of LED light fixture module are controlled in real time; Reduce the operation energy consumption of radiator fan, guaranteed the security of operation of LED light fixture module.In addition, require extremely strict stage to noise especially, the utility model is provided with four radiating fan rotation speed gears, and the user can select suitable radiating fan rotation speed gear according to the requirement of different stages to noise.In sum, the utility model provides the approach of LED light fixture module operation noise being controlled under the different use occasions for the user.
Description of drawings
Fig. 1 is the control system structural representation of the utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Stage as shown in Figure 1 is with LED spotlight cooling control system; Comprise radiator fan and LED light fixture module; It comprises that also each gear maximum speed of CPU, temperature sensor and radiator fan is provided with module; Wherein, the luminance signal output of CPU connects LED light fixture module, and the fan rotating speed signals output of CPU connects radiator fan; The temperature signal input of CPU connects the signal output part of temperature sensor, and each gear maximum speed of radiator fan is provided with the signal input part of the signal output part connection CPU of module.The VT of CPU is connected with display.The signal input part of CPU is connected with input keyboard.
In the technique scheme, it also comprises the radiator that is arranged on the LED light fixture module, and said radiator connects temperature sensor.Radiator and radiator fan dispel the heat to LED light fixture module jointly.
When technique scheme was used, radiator fan was installed in by the LED light fixture module.
The course of work of the utility model is: the user is provided with the rank of radiator fan running speed according to the scene to the requirement of equipment operation noise, for example requires noise to be no more than 30dB, then should select the 3rd grade.
When the LED of equipment light fixture module was worked, its temperature was through being fixed on the temperature sensor collection on the radiator and feeding back among the CPU, and CPU comes to regulate automatically the speed of service of radiator fan according to the size of temperature value.
When the speed of service of radiator fan has reached the rank (as above the 3rd grade of speed of service in the example) that the user is provided with; And when the temperature of LED light fixture module still continues to rise; CPU will reduce the output brightness of LED light fixture module automatically; Because the output brightness of LED light fixture module and its caloric value have linear relationship, so this behave meeting reduces the operating temperature of LED light fixture module.When if the temperature of LED light fixture module still exceeds limits value, the output brightness that CPU will continue minimizing LED light fixture module meets the requirements until temperature.
More than design can avoid LED light fixture module because of the overheated damage that causes, and also guarantees that LED light fixture module operation noise is no more than the allowed band of environment for use simultaneously.
The content that this specification is not done to describe in detail belongs to this area professional and technical personnel's known prior art.
