Description

A kind of the colour temperature setting method and its circuit of intelligence light-adjustable LED lamp

Technical field

The present invention relates to a kind of intelligent light-adjustable LED lamps, are arranged more particularly, to a kind of colour temperature of intelligent light-adjustable LED lamp Method and its circuit.

Background technique

Existing light modulation lighting system generally includes light modulator and at least one light-adjustable LED lamp, and light modulator generally includes Switch and brightness regulator, as shown in Figure 1, the input terminal of brightness regulator is connect by switch with the firewire of alternating current, tunable optical LED light has firewire input terminal and zero curve input terminal, and the output end of brightness regulator and the firewire input terminal of light-adjustable LED lamp connect It connects, the zero curve of the zero curve input terminal connection alternating current of light-adjustable LED lamp.When the switch of light modulator is in closed state (position of turning on light) When, light-adjustable LED lamp is lit, by operating brightness regulator, the brightness of adjustable light-adjustable LED lamp, when light modulator When switch is in an off state (position of turning off the light), two input terminals (zero curve input terminal and firewire input terminal) of light-adjustable LED lamp Between voltage be zero, light-adjustable LED lamp does not work.Light modulator passes through the city to access when adjusting the brightness of light-adjustable LED lamp Electric sine wave alternating current pressure carries out chop control, becomes zero the alternating voltage of script sinusoidal waveform at the time of being not zero, from And change the effective voltage between two input terminals of light-adjustable LED lamp, the effective voltage between two input terminals of light-adjustable LED lamp Bigger, light-adjustable LED lamp luminous intensity is higher, light-adjustable LED lamp shine it is brighter, conversely, two input terminals of light-adjustable LED lamp it Between effective voltage it is smaller, the luminous intensity of light-adjustable LED lamp is lower, light-adjustable LED lamp shine it is darker.

Current research show human body to the comfort of light environment, it is not only related with brightness (i.e. intensity of illumination), also with light Related according to the colour temperature under intensity, when the matching degree of brightness and colour temperature is higher, light environment has preferable comfort level.Traditional Light-adjustable LED lamp can only adjust brightness under the control of light modulator, can not provide to user more comfortable under different brightness Light environment is not able to satisfy current demand more and more.Also occurs a kind of tunable optical with color temperature adjustment function in recent years LED light is provided with the table of comparisons of switch change-over rule and colour temperature in the light-adjustable LED lamp, when in use first, in accordance with set Switch change-over rule operates the switch of light modulator, realizes the selection of colour temperature, after selecting to determine certain colour temperature, passes through brightness tune Device is saved to adjust the brightness under this colour temperature.But the mode of the selection colour temperature of the light-adjustable LED lamp is limited to switch change-over rule, General only there are three types of optional colour temperatures, and cannot continuously adjust colour temperature, and sometimes, could select after multi-pass operation to switch To suitable colour temperature, and after being provided with colour temperature, thereafter during light modulation, colour temperature is remained unchanged, if to change Colour temperature needs to reset, and use is not very convenient.

Summary of the invention

The first technical problem to be solved by the present invention is to provide a kind of colour temperature setting method of intelligent light-adjustable LED lamp, In the colour temperature setting method, colour temperature is capable of the transformation of biggish color temperature change range periodically, and user can become in colour temperature The change of the brightness and colour temperature that select one of colour temperature to be set, and stored in intelligent light-adjustable LED lamp during changing Change corresponding relationship formula, can brightness using the colour temperature of setting and when colour temperature be arranged as foundation, be updated automatically, generation is fitted The newest brightness and color temperature change corresponding relationship formula of user is closed, to meet the needs of user is to light environment comfort level, In subsequent adjustment brightness, colour temperature is generated according to brightness and colour temperature corresponding relationship.

The present invention solves technical solution used by one of above-mentioned technical problem are as follows: a kind of color of intelligence light-adjustable LED lamp Warm setting method, comprising the following steps:

(1) to intelligent light-adjustable LED lamp be in turn on light state when, the mode of operation of the switch of light modulator is defined: when The switch of light modulator disconnects and turn-off time is more than or equal to t1, and the Operation Definition by the switch of such light modulator is opening after turning off the light Lamp operation, when the switch of light modulator, which turn off the light, to be operated, intelligent light-adjustable LED lamp switches into shape of turning off the light by the state of turning on light State, t1 are preset according to the switch operating habit of commonly used person, the size of this time is generally 5 seconds or so；Work as light modulator Switch time for first being disconnected and being then connected again, and being disconnected when being greater than 20 milliseconds and being less than t1, by opening for such light modulator The on-off line operation of pass is defined as having carried out one-time continuous switch operation, and continuous switch operation twice is as in one group, every group, and first Intelligence light-adjustable LED lamp enters colour temperature setting state when secondary continuous switch operates, intelligently adjustable when continuous switch operation for the second time Light LED light is considered determination of the user after selecting colour temperature, exits colour temperature setting state；
