Abstract
The color-temperature-adjustable light-emitting diode (LED) lamp circuit comprises three parallel branches. A plurality of LED light sources and a plurality of resistors are in serial connection on the three parallel branches. The LED light sources on the branches are different in color temperature. By means of a double-pole triple-throw switch, current of the LED light sources on two branches can be simultaneously controlled to achieve the purpose of adjusting color temperature of the LED light sources by using effects on current on the color temperature of the light sources. Appropriate color temperature can be selected according to different requirements of people and surrounding environments to meet daily life requirements.
Description
Technical field
The utility model relates to the LED lighting, particularly the LED lamp circuit of adjustable color temperature.
Background technology
Light source color temperature is different, and photochromic also different: colour temperature is below 3300K, and the photochromic red partially warm sensation of giving has steady atmosphere, warm sensation; Colour temperature is middle at 3000～6000K, and the people does not have especially significantly visual psychology effect under this tone, frank sensation is arranged, so be called " neutrality " colour temperature; Colour temperature surpasses 6000K, and photochromic inclined to one side indigo plant is given chilly sensation.Under the high color temperature light source irradiation, like the not high atmosphere that a kind of cloudy gas is then arranged to people of brightness; Under the low color temperature light sources irradiation, the too high meeting of brightness has a kind of sultry sensation to people.
Along with environment is different to the accommodation of colour temperature with people, increasingly high to the requirement of regulating light source color temperature.But present most of LED light fixture does not possess the function of regulating colour temperature, can not satisfy people's specific (special) requirements.
The utility model content
The utility model has carried out research and has improved to the existing uncontrollable shortcoming of LED light fixture colour temperature, and a kind of LED lamp circuit of adjustable color temperature is provided, and adopts to change the LED that size of current drives different-colour, finally reaches stable different-colour.
The technical scheme of the utility model is following:
A kind of LED lamp circuit of adjustable color temperature; Comprise first branch road parallel with one another, second branch road and the 3rd branch road; Said first route the 4th resistance, first resistance and a plurality of led light source are composed in series; Said second route second resistance and a plurality of led light source are composed in series, and said the 3rd route the 5th resistance, the 3rd resistance and a plurality of led light source are composed in series; The quantity of the led light source on said first branch road, second branch road and the 3rd branch road equates, and the colour temperature magnitude relationship of the led light source on each branch road is: first branch road < second branch road < the 3rd branch road; Also comprise the DPTT double-pole triple throw switch; Said DPTT double-pole triple throw switch first on fixed contact between the 4th resistance and first resistance, fixed contact is unsettled on second, in first in the fixed contact and second fixed contact unsettled; First time fixed contact is unsettled, and second time fixed contact is between the 5th resistance and the 3rd resistance; First moving contact is between the 4th resistance and power supply, and second moving contact is between the 5th resistance and power supply.
Its further technical scheme is: the quantity of the led light source on said first branch road, second branch road, the 3rd branch road is respectively 6.
And its further technical scheme is: the colour temperature of the led light source on said first branch road, second branch road, the 3rd branch road is respectively 2700K, 4000K, 5700K.
The useful technique effect of the utility model is:
The utility model adopts the DPTT double-pole triple throw switch; Control the size of current of two circuits simultaneously; Applied current is to the influence of light source color temperature; Reach the purpose of regulating the led light source colour temperature, can select according to people's different demands with to the suitable colour temperature of carrying out of surrounding environment, to satisfy the daily life demand.
Description of drawings
Fig. 1 is the circuit theory diagrams of a kind of embodiment of the utility model.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1,18 led light sources adopt 6 strings 3 mode also among the embodiment, and the colour temperature of led light source D1～D6 is 2700K, and the colour temperature of led light source D7～D12 is 4000K, and the colour temperature of led light source D13 ~ D18 is 5700K.The positive pole of series LED light source D1～D6 is connected with the anodal V+ of DC 24V, and negative pole series resistance R1, resistance R 4 backs successively is connected with the negative pole V-of DC 24V.The positive pole of series LED light source D7～D12 is connected with the anodal V+ of DC 24V, is connected with the negative pole V-of DC 24V behind the negative pole series resistance R2.The positive pole of series LED light source D13～D18 is connected with the anodal V+ of DC 24V, and negative pole series resistance R3, resistance R 5 backs successively is connected with the negative pole V-of DC 24V.
DPTT double-pole triple throw switch (hereinafter to be referred as switch) S1 first on fixed contact between resistance R 4 and resistance R 1; Fixed contact in the fixed contact, second in the fixed contact, first on second, first time fixed contact are all unsettled, and second time fixed contact is between resistance R 5 and resistance R 3.Two moving contacts all are connected with the negative pole V-of DC 24V.
The operation principle of the utility model is following:
When initial condition, switch S 1 places bay (first, second fixed contact), and the last electric current that flows through of led light source D1～D6 and D13～D18 is less, and colour temperature is minimum.
Shelves are (fixed contact first, second on) time above switch S 1 places, and the resistance R 4 of connecting with led light source D1 ~ D6 is by short circuit, electric current increase, the also corresponding increase of the colour temperature of led light source D1～D6; The electric current of led light source D13～D18 is less, and colour temperature is relatively low.Bay increases in the whole colour temperature ratio, but because the led light source D13 ~ D18 of high colour temperature is bigger to the influence of whole colour temperature, therefore whole colour temperature is still on the low side.
When below switch S 1 places shelves (first, second down fixed contact) time, the electric current of led light source D1～D6 is less, and colour temperature is lower; The resistance R 5 of connecting with led light source D13～D18 is by short circuit, and electric current increases, and the colour temperature of led light source D13～D18 increases relatively.Whole colour temperature is the highest.
Adopt thus to change the led light source that size of current drives different-colour, and then change the colour temperature of two led light sources on the circuit, can realize the conversion of high, normal, basic gear colour temperature.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of spirit that does not break away from the utility model and design, all should think to be included within the protection range of the utility model.
