Detailed Description

In order to solve the problems, the patent provides a novel intelligent color-mixing lamp and a control method of the intelligent color-mixing lamp, and the intelligent color-mixing lamp has the functions of remote control, text information display and the like.

Fig. 1 is a schematic structural diagram of an intelligent color-adjustable lamp in an embodiment of the present application.

In this embodiment, the intelligent color-tunable light fixture includes: a luminaire 101, a local network control module 102 and a temperature sensor 103.

The lamp 101 at least includes a first light source and a second light source, and the colors of the lights emitted from the first light source and the second light source are different, so as to provide the lights. In some embodiments, the first light source provides red illumination and the second light source provides white illumination.

In other embodiments, the luminaire 101 further comprises a third light source and a fourth light source, wherein the third light source is configured to provide green illumination and the fourth light source is configured to provide blue illumination. The different proportions of the four illumination colors can correspond to different light-emitting colors of the lamp, so that the light-emitting colors of the lamp can be switched at least on the black body line of the sun, and even the colors in a large range of the CIE1931 color gamut diagram can be realized.

In this embodiment, the control of the light emitting color of the luminaire can be implemented by the local network control module 102. The local network control module is realized by a Bluetooth chip with an ARM core, and the Bluetooth chip with the ARM core supports high-speed floating point operation.

The local network control module 102 can control each light source to output light with different light intensity proportions according to the color matching scheme table and aiming at the light emitting instructions with different colors, so that the overall emitting color of the lamp is blended, and the direct control of the light emitting color of the lamp is realized. When the local network control module 102 is connected to another network or a mesh point as a mesh point, the local network control module 102 may also be transmitted with control information by another network or mesh point to control the light emission of the lamp.

In an embodiment with four light sources, the local network control module 102 is configured to control the light emitting intensity ratios of the first light source, the second light source, the third light source and the fourth light source according to the temperature detected by the temperature sensor, so as to realize light emitting of multiple colors.

For example, in an embodiment with four light sources, if the command received by the local network control module 102 is to emit purple light, the ratio of the light intensities emitted by the first light source to the fourth light source may be 1:1:0:1, the red light of the first light source is mixed with the blue light of the fourth light source to obtain the required purple light, and the white light of the second light source is used to adjust the overall color rendering degree of the light emitted by the luminaire.

In some embodiments, in controlling the light emitting ratio of each light source, the control information received by the local network control module 102 is a CCT color temperature value including a standard of a target color, or a standard group of an RGB color system, an HSL color system, or the like. These color temperature values or sets of criteria may be converted into electrical signals that are input to the first through fourth light sources to effect the final control. Moreover, the local network control module 102 in the present application performs light-emitting matching of the first to fourth light sources according to the color mixing principle, and allocates the second light source, i.e., the white light source, so as to achieve the effect of high color rendering index. For the same color, the higher the color rendering index is, the lower the difference between the spectrum and the natural light is, and the better the color rendering performance is.

In some embodiments, the intelligent color-mixing lamp further includes a storage module, connected to the local network control module, and at least configured to store a color scheme table, and calibration parameters and temperature compensation parameters, where the calibration parameters include calibration parameters of each of the light sources, and the temperature compensation parameters include compensation parameters for emitting different colors of light at different temperatures, so as to be called by the local network control module.

The calibration parameters and the temperature compensation parameters can help color development correction of the lamp, and output of fidelity colors is facilitated. And, in some embodiments, acquiring the calibration parameter includes:

1. giving different electrical parameters, and acquiring the light emitting conditions of each light source under the different electrical parameters, wherein the light emitting conditions comprise light emitting intensity and light emitting color;

2. and comparing the obtained test result with the result of calibration when each light source leaves the factory to obtain the calibration parameter.

When the temperature compensation parameters are obtained, the method comprises the following steps:

1. under different temperature environments, obtaining the light emitting conditions of all light sources under the same electrical parameter, wherein the light emitting conditions comprise light emitting intensity and light emitting color;

2. and comparing the light emitting conditions of the light sources under different temperature environments to obtain the temperature compensation parameters.

In the embodiments with the storage module and the light sources of four colors, for different color temperatures, a table can be generated in a laboratory according to the lamp bead of a selected type, the ratio of the red light source and the white light source at different color temperatures is corresponded, and a ratio with the highest color rendering index is measured and calculated through the integrating sphere, and the ratio can be stored in the color scheme table, so that in actual control, the color rendering indexes of the outputs of the RGBW four-way light source at different color temperatures are at least larger than a preset value.

In some embodiments, the preset value is greater than or equal to 90, which corresponds to excellent color rendering performance and can be applied to places requiring precise color contrast.

In some embodiments, since the different light sources of the luminaire are realized by different colored LED beads, each bead is mounted on a luminaire substrate, and the temperature sensor is also mounted on the luminaire substrate for detecting the substrate temperature and is arranged close to the beads so as to convert to the temperature of the beads.

Therefore, in some embodiments, the local network control module 102 is further configured to adjust the light intensity of each light source according to the temperature detected by the temperature sensor, so as to perform an effect of compensating for the attenuation.

In some embodiments, the LED lamp beads are lamp beads that have undergone factory calibration, and the calibration data is stored in the local network control module 102, and when actually emitting light, the calibration data of the LED lamp beads needs to be considered in addition to some cases of light-emitting attenuation caused by temperature. Both calibration data and temperature are taken as input when calculating the color point, thereby providing a more accurate calculation.

At this time, in combination with the above embodiment having the storage module and four light sources, the local network control module 102 may calculate the outputs of the blue light source and the green light source based on the red light source and the white light source in the table, and the calibration value of the LED lamp bead during production, and the temperature detected by the temperature sensor, and optimize the outputs of the RGBW four-way of the maximum illuminance at the current color temperature.

The remote control terminal 201 may be a mobile terminal or a separate controller, and may also be connected to a network where a local network control module of the intelligent color-adjusting lamp is located, or connected to the local network control module as a network point.

The local network control module comprises at least one of a Bluetooth unit, an infrared unit, a Zigbee unit and an NB-IoT unit. These units are implemented on a chip with an ARM core, enabling high speed floating point operations.

The number of the lamps is at least one, each lamp is correspondingly connected to one local network control module, a plurality of local network control modules can be connected to the same local network control module, and the local network control modules identify the local network control modules through unique identity codes of the local network control modules.
