Detailed description of the invention
Fig. 1 is the sectional view of first embodiment of the invention thermochromism LED 100, and comprise body 10, substrate 20, lighting unit 340, this substrate 20 is arranged on the end face of this body 10, and this lighting unit 340 comprises two LED light sources 30 and thermochromism device 40.These two LED light sources 30 are arranged on the top of this substrate 20 and thermally coupled with this substrate 20.This thermochromism device 40 is transparent or semitransparent shell structure, and this thermochromism device 40 to be arranged on above this LED light source 30 and thermally coupled with this substrate 20.The discoloring temperature of this thermochromism device 40 is in the range of temperature of this substrate 20, and when the temperature on this substrate 20 changes, the color of this thermochromism device 40 changes.
Please refer to Fig. 1, also comprise multiple LED light source 30, corresponding each LED light source 30 is respectively equipped with a thermochromism device 40.This thermochromism device 40 is arch shell-like structure, this thermochromism device 40 is located at around this LED light source 30, the inner surface of this thermochromism device 40 is coated with thermochromic material 41, and the characteristic of this thermochromic material 41 is the switching that color can occur when experiencing variations in temperature.
Please refer to Fig. 1, also comprise reflector 50 and lens 60, this reflector 50 is arranged on around this lighting unit 340, and these lens 60 are arranged on the top of this lighting unit 340, the light that this reflector 50 sends for reflecting this lighting unit 340 towards these lens 60.
Please refer to Fig. 1, this thermochromism LED 100 is for plant illumination, and these LED light sources 30 are white light source, and when the temperature on this substrate 20 is lower, the color of this thermochromism device 40 remains unchanged; When the temperature on this substrate 20 is higher, the color of this thermochromism device 40 changes, and becomes colorless.And realize controlling to the temperature of this substrate 20 the control system (not shown) that is to arrange driver (not shown) and control this driver, this driver and this set-up of control system are in this body 10, this driver is used for providing power supply to these LED light sources 30, and this control system can control the size of this driver to the power of this LED light source 30 out-put supply.When the power exported to this LED light source 30 is higher, the heat that this LED light source 30 produces is more, and this raises causing the temperature of this substrate 20 very soon, thus affects the color change of this thermochromism device 40.This thermochromic material 41 is blue thermochromic material or red thermochromic material or purple thermochromic material.For the setting of this thermochromic material 41, wherein a kind of embodiment scribbles blue thermochromic material in the half of the inner surface of this thermochromism device 40, second half is provided with red thermochromic material, and the discoloring temperature of these two kinds of thermochromic materials is identical or close, when the temperature of this substrate 20 changes, the color of this blue thermochromic material and this red thermochromic material changes simultaneously.
In the course of work, when the temperature on this substrate 20 is lower, this thermochromic material 41 variable color cannot be made, the color of this thermochromism device 40 remains unchanged, half due to the inner surface of this thermochromism device 40 scribbles blue thermochromic material, second half is provided with red thermochromic material, therefore when the light of this LED light source 30 is absorbed through this thermochromism device 40 rear section light efficiency, the only mixed light of remaining blue light and ruddiness, this mixed light can reach the effect of Promoting plant growth pattern.Therefore this thermochromism LED 100 is in plant illumination pattern.When the temperature on this substrate 20 is higher, after the temperature of this thermochromism device 40 raises gradually so that exceedes the transition temperature of this thermochromic material 41, this thermochromic material 41 becomes colorless, the light of this LED light source 30 can not be absorbed through after this thermochromism device 40, output remains white light, and now this thermochromism LED 100 starts white-light illuminating pattern.
In sum, this thermochromism LED 100 by arranging thermochromism device 40 above this LED light source 30, and make this thermochromism device 40 thermally coupled with the substrate 20 of this LED light source 30 of carrying, color can be there is and switch in the characteristic due to this thermochromism device 40 when being its experience variations in temperature, this thermochromism LED 100 is by realizing the control to this thermochromism device 40 temperature to the control of this substrate 20 temperature, thus realize, to the control of this thermochromism device 40 color switching, finally realizing the adjustment this LED light source 30 being gone out to light color temperature.Can realize the switching between plant growth pattern and white-light illuminating pattern two kinds of light illumination modes when this thermochromism LED 100 is used for plant illumination, therefore this thermochromism LED 100 can provide multiple light illumination mode, has the advantage of light modulation toning.
