Unit processed is corresponding with the soft-touch control of susceptor surface.The LED light of different brightness is just easily achieved by operating soft-touch control
Source exports, if the brightness of the brightness of white LED light source, feux rouges and orange light LED is adjusted simultaneously, while movable guard page is not unfolded,
So brightness of light source is mixed by light after the diffusing reflection of lampshade inner wall and realizes that the light of different-colour is adjusted, and from desk lamp
Soft uniform light is projected in bottom, meets requirement of the office space to different-colour light quality；When expansion movable guard page, white light is allowed
LED light source direct projection obtains the poly- spot light of larger range of exposures, can meet the specific use of desk lamp, such as clock and watch into illumination space
The working environments such as repairing and circuit detection.If single adjusting red-light LED or orange light LED, red-letter day warm atmosphere can be set off by contrast.
Embodiment two
The implementation process of this example, most of identical with embodiment one, different contents mainly has at following 2 points：
1) lampshade is made of fixed cover page and a movable guard page, 12W red-light LEDs (long 620mm of spike or so), 12W
Green light LED (long 540nm of spike or so) and 12W blue-ray LEDs (465nm or so) are installed by the be staggered light source board of composition of matrix
On the inner wall of same movable guard page, the driving current of this each color LED is by power supply microcontroller independent control.
2) upper end of movable guard page with fixed cover page is connected by shaft, and shaft is the recessed circular groove by movable guard page
123 interlock to realize with fixing the convex cylindrical 112 of cover page, as shown in Fig. 7a-7c.Recessed circular groove and movable guard page are by processing one
Body shapes, and convex cylindrical and fixed cover page are also integrally formed by processing.The lower end of lampshade movable guard page is logical with fixed cover page
Buckle 121 is crossed to realize the folding of movable guard page, buckle is buckled using magnetic force.
By the soft-touch control on operation base surface, the LED light source output of different colours brightness easy to implement.If simultaneously
The different brightness of red-light LED, green light LED and blue-ray LED are adjusted, the light output of different-colour value are just obtained, if movable guard page
Be not unfolded, light after the high diffusing reflection of lampshade inner wall, and from lampshade bottom output different-colour soft uniform light.It is if living
Dynamic cover page expansion, if single one kind adjusted in these three colors and two kinds, the large space around desk lamp is dried in certain color
Hold in the palm life atmosphere.If adjusting these three colors simultaneously, white light output can be mixed to get, the white light scope of desk lamp is expanded
Greatly, the more multipurpose of desk lamp can be met.
