Applied for the utility model patent of the full-color lamp of a kind of LED before our company, when being applied to the scheme of this full-color lamp on the desk lamp, can having made and have the LED desk lamp that full color shows, made the desk lamp feature richness, used as lampion.Yet because the position that desk lamp is placed is different; The desk lamp in parlor and living room for example; Mode of often using and people have a great difference to the requirement of light, and the desk lamp in parlor need have multiple color effects, and the often needs in living room is to reassure the public and warm light.Full-color colored lights can satisfy for the conversion of multicolour and color; Be applied to the parlor and can have good effect; But the various colors that also seldom need a lot of conversion in the living room; Main still need or grave and stern white light or warm dizzy gold-tinted play illumination and regulate the effect of mood, thus but full-color colored lights does not have colour temperature to be regulated and can not see through the effect that light is regulated the cold and warm tone in the room.
Summary of the invention
The utility model technical problem to be solved provides a kind of colour temperature adjustable LED desk lamp, solves the defective that present LED desk lamp does not have the colour temperature regulatory function.
Technical scheme
A kind of colour temperature adjustable LED desk lamp; Comprise reddish yellow primary colors LED luminous tube; The LED driving governor and the power switch of driving LED luminous tube; It is characterized in that: also comprise the colour temperature induction module, said colour temperature induction module is to select from brilliant white to deep yellow various white light colors and gold-tinted color, and the signal receiving module of microprocessor receives the chrominance signal that the colour temperature induction module transmits; Color through microprocessor decomposes each LED driving governor that synthesis module is sent to control signal driving primitive colours LED luminous tube respectively, and said LED driving governor is through changing the drive current control LED luminous tube brightness of LED luminous tube.
Said colour temperature induction module adopts the capacitive induction touch electrode of strip.
Also comprise the color induction module, said color induction module links to each other with the signal receiving module of microprocessor for selecting the various colors of full color, sends chrominance signal to microprocessor.
Said color induction module adopts the capacitive induction touch electrode of strip.
Said power switch comprises change-over switch and functional select switch; Change-over switch links to each other with functional select switch with power supply respectively; Functional select switch links to each other with the signal receiving module of microprocessor, selects the chrominance signal of colour temperature induction module transmission or the chrominance signal that the color induction module transmits.
Beneficial effect
The colour temperature adjustable LED desk lamp of the utility model has increased colour temperature and has regulated pattern; The user who gives desk lamp is the light regulative mode of the warmth of hommization more; After the light adjusting pattern of comprehensive full color, the desk lamp of the utility model can be applicable to various places widely, and range of application is bigger.
Description of drawings
Fig. 1 is the utility model principle schematic.
Fig. 2 is the utility model touch electrode panel sketch map.
Wherein: 1-LED luminous tube, 2-LED driving governor, 3-power switch, 4-colour temperature induction module, 5-microprocessor, 6-color induction module.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, further set forth the utility model.
A kind of colour temperature adjustable LED desk lamp; The LED luminous tube 1 that comprises the reddish yellow primary colors; The LED driving governor 2 and the power switch 3 of driving LED luminous tube 1; Also comprise colour temperature induction module 4; Said colour temperature induction module 4 is to select from brilliant white to deep yellow various white light colors and gold-tinted color, and the signal receiving module of microprocessor 5 receives the chrominance signal that colour temperature induction module 4 transmits, and respectively control signal is sent to each LED driving governor 2 of the trichromatic LED luminous tube 1 of driving through the color decomposition synthesis module of microprocessor 5; Said LED driving governor 2 changes the brightness of three LED luminous tubes of drive current control of LED luminous tube 1 through gathering the pwm signal that microprocessor 5 sends.
Said colour temperature induction module 4 adopts the capacitive induction touch electrode of strip.
Comprehensive again color induction module 6; Said color induction module 6 also adopts the capacitive induction touch electrode of strip; Color induction module 6 links to each other with the signal receiving module of microprocessor 5 for selecting the various colors of full color, sends chrominance signal to microprocessor 5.
Said power switch 3 comprises change-over switch and functional select switch; Change-over switch links to each other with functional select switch with power supply respectively; Functional select switch links to each other with the signal receiving module of microprocessor 5, selects the chrominance signal of colour temperature induction module 4 transmission or the chrominance signal that color induction module 6 transmits.
Shown in accompanying drawing 1, microprocessor 5 is used for touch sensible signal and the collection of power switch key-press status, Treatment Analysis, pwm signal output.Touch sensible electrode and microprocessor 5 are arranged on the pcb board, plastic front board and pcb board are held tightly together, be printed on the multicolour pattern of two kinds of modules on the position panel of corresponding touch sensible electrode, shown in accompanying drawing 2.When finger was on the deserved induction panel of touch sensible electrode pair, the electric charge on the induction electrode changed, and microprocessor 5 is gathered signal processing analysis, and the output pwm control signal.
LED driving governor 2 receives the pwm signal of microprocessor 5 outputs on the pcb boards, according to the size of current of the duty cycle adjustment driving LED luminous tube 1 of pwm signal, and the brightness of redness, green, blue led luminous tube 1 is changed thereupon
