Description
[technical field]
The present invention relates to a kind of headlamp by temperature control colour temperature.
[background technology]
In to the more sensitive environment of temperature, such as the place such as meeting room, library, examination, it is desirable to it is persevering to environment
Constant temperature degree, but actual temperature is difficult to accurate control, different degrees of temperature fluctuation easily occurs, influences people to environment
Comfort.
Some researches show that, by the colour temperature of houselights finely tune it is psychological feel to change the sensation in Human Physiology,
So as to reach the comfort improved to environment temperature.
[content of the invention]
The invention overcomes the shortcomings of the above-mentioned technology and provides a kind of headlamp by temperature control colour temperature, pass through detection
Environment temperature changes the color of houselights, so as to improve comfort of the human body to environment temperature by vision.
To achieve the above object, present invention employs following technical proposal：
A kind of headlamp by temperature control colour temperature, includes lamp housing 1, and the lamp housing 1 is equipped with controller 2, cold color temperature lamp 3
With warm color temperature lamp 4, the controller 2 be connected with for detect environment temperature temperature sensor 5, the temperature for preset temperature value
Angle value preinstalled circuit 6, cool colour temperature lamp driver 7 and warm colour temperature lamp driver 8, the cool colour temperature lamp driver 7 and cool colour temperature
Lamp 3 connects, and the warm colour temperature lamp driver 8 is connected with warm color temperature lamp 4.
The temperature value preinstalled circuit 6 sets datum by electric resistance partial pressure or voltage-reference and realizes preset temperature
Value.
The cool colour temperature lamp driver 7 is the cool colour temperature lamp driver of processing duty cycle signals.
The warm colour temperature lamp driver 8 is the warm colour temperature lamp driver of processing duty cycle signals.
The beneficial effects of the invention are as follows：
The present invention changes the color of houselights by detecting environment temperature, so as to improve human body to ring by vision
The comfort of border temperature, moreover it is possible to which light colour temperature is adjusted to change by varying temperature value preinstalled circuit according to different environmental demands
Fiducial temperature.
[brief description of the drawings]
Fig. 1 is the schematic diagram of the present invention.
[embodiment]
It is described in further detail below in conjunction with the accompanying drawings with embodiments of the present invention：
As shown in Figure 1, a kind of headlamp by temperature control colour temperature, includes lamp housing 1, the lamp housing 1 is equipped with controller
2nd, cold color temperature lamp 3 and warm color temperature lamp 4, the controller 2 be connected with for detect environment temperature temperature sensor 5, for pre-
If the temperature value preinstalled circuit 6 of temperature value, cool colour temperature lamp driver 7 and warm colour temperature lamp driver 8, the cold color temperature lamp driving
Device 7 is connected with cold color temperature lamp 3, and the warm colour temperature lamp driver 8 is connected with warm color temperature lamp 4.
Wherein, the cool colour temperature lamp driver 7 for processing duty cycle signals cool colour temperature lamp driver, the warm color temperature lamp
Driver 8 is the warm colour temperature lamp driver of processing duty cycle signals.
Operation principle：When headlamp works, temperature sensor 5 constantly detects environment temperature, and with temperature value preinstalled circuit 6
In preset temperature value contrasted, when the ambient temperature value of detection is equal to preset temperature value, controller 2 is respectively to cool colour temperature
The duty cycle signals of lamp driver 7 and 8 the output phase of warm colour temperature lamp driver together, so as to drive cold color temperature lamp 3 to be sent out with warm color temperature lamp 4
Go out the light of same brightness；When the ambient temperature value of detection is higher than preset temperature value, controller 2 is defeated to cool colour temperature lamp driver 7
The duty cycle signals gone out are higher than the duty cycle signals of warm colour temperature lamp driver 8,3 brightness of cool colour temperature is higher than warm color temperature lamp 4；When
When the ambient temperature value of detection is less than preset temperature value, the duty cycle signals that controller 2 is exported to warm colour temperature lamp driver 8 are higher than
The duty cycle signals of cool colour temperature lamp driver 7, make warm 4 brightness of color temperature lamp be higher than cool colour temperature 3.
The temperature value preinstalled circuit 6 sets datum by electric resistance partial pressure or voltage-reference and realizes preset temperature
Value, uses different temperatures value preinstalled circuit 6 according to different demands, improves accuracy.
