Description
Technical Field
The present disclosure relates to light emitting devices, and particularly to a light emitting device for controlling light color output of a lamp.
Background
Besides the need of dimming, the lighting needs to be provided with different light color changes in some specific situations to meet the needs of the use situation. For example, stage performance entertainment venues and work homes have different situation requirements for the color of the lighting to achieve special effects.
In the control technology of lighting color, the lighting color mainly includes two categories:
(1) conventional optical filter methods: the color control is a color matching method of color subtraction in the color science aiming at the color change control mode of the traditional wide-spectrum light source. The disadvantage is that the luminosity decreases in the color of the light to be tuned out by subtraction. The advantage is that the same light color can be produced on glass and other high molecular transparent materials by using optical coating or dye in a fixed formula mode under a stable light source (spectrum). In addition, the light color control in the optical filter method mainly comes from the spectral transmittance of the light-transmitting material. If the transmittance of the spectrum is fixed, the light color can be kept stable repeatedly and consistently, which is the greatest advantage of the traditional optical filter method in light color control. In the conventional optical filter method, the light path structure of the controllable color between the light color filter and the illumination light source must be considered in the device structure of the illumination. In addition, if the light color needs to be automatically or flexibly controlled, a variable device must be introduced into the control structure, which results in a complex mechanism and a large lamp structure. This approach conflicts with the current demand for miniaturization and miniaturization of lighting devices.
(2) Electronic drive control method: the control method is mainly directed to the solid-state light-emitting material. The light color of the LED is different according to the combination of the materials, and different spectrums are generated. The color mixing addition is carried out by utilizing the single light colors which are respectively different in the light color areas of human vision and the principle of the color mixing addition of more than two (including two) solid-state light-emitting diodes, and the specific light colors in the color gamut range of the color mixing addition are produced. The most advantage of this method is that the color adjustment control adopts a color-adding color-mixing method. Besides, the luminosity of the adjusted light color is not easy to decrease, and the light color of the solid-state light-emitting diode has the characteristic of higher chroma, so that the light color with higher chroma is easier to adjust. Because the related lighting devices all adopt monochromatic lights of more than three (including three) solid-state Light Emitting Diodes (LEDs) such as red, green, blue and white, the single light color change is based on the relative light intensity change as the light color adjustment change. The corresponding relative variation range is the luminosity variation of various monochromatic light sources in the lamp by relative percentage or by adopting DAC (digital-to-analog conversion) relative variation, so that the aim of color mixing is achieved by mixing the luminosity variation of various monochromatic light sources in the lamp. Because the spectrum (light color) of the light emitting diode cannot be maintained to a stable spectrum wavelength and a stable luminosity range during output, the light color in the light emitting diode lighting lamp is controlled by adopting an electronic driving mode, and the light color cannot be copied to a specific required light color under the adjustment of relative change because the conditions of absolute number quantization of the basic spectrum (absolute luminosity and absolute chromaticity) of the spectrum (light color) are different, so that the difference of inconsistent light colors is generated between the lamps, or the light color cannot reach a certain same light color even if the light color adjustment is repeated under the condition of the same lamp.
In the current lighting and display light source, the solid-state diode light source has the greatest difficulty in use effect in the mainstream market and under consideration of a plurality of factors such as energy conservation and the like: the method has the advantages that the method cannot maintain the light color of related products, and the effect of consistent light color can be maintained before and after time and in different batches.

Detailed Description
Fig. 1 is a schematic block diagram of a control device according to an embodiment of the present invention. Referring to fig. 1, a control device 100 according to an embodiment of the present invention is suitable for controlling the output light color of a lamp 200. The control device 100 includes a connection unit 110, a driving unit 120, and a control unit 130. The driving unit 120 is electrically connected to the connection unit 110. The control unit 130 is electrically connected to the driving unit 120 and electrically connected to the lamp 200 through the connection unit 110. The control unit 130 identifies the identification code 220 of the lamp 200, and controls the driving unit 120 to output a driving signal to the lamp 200 according to the identification code 220, so that the multiple sets of photochromic elements 210 of the lamp 200 emit light.
In the present embodiment, the lamp 200 is, for example, a Light Emitting Diode (LED). In one embodiment, the lamp 200 may also be a Cold Cathode Fluorescent Lamp (CCFL). However, the invention is not limited thereto, and other suitable lamps are also included in the scope of the invention. Furthermore, in order to make the lamp 200 emit light with variable light colors, the lamp 200 at least includes two sets of light color elements 210 with different light colors. For example, the light fixture 200 may have red, green, and blue light emitting diodes.
Furthermore, in the present embodiment, the identification code 220 of the lamp 200 is used to enable the control device 100 to identify the lamp 200. The control device 100 further obtains spectral data, photometric (photometric) data, and colorimetric (colorimetric) data of each set of the color elements 210 of the lamp 200 according to the identification code 220 of the lamp 200. The identification code 220 may be built in the luminaire 200, for example, a storage element stored in the luminaire. When the connection unit 110 of the control device 100 is connected to the luminaire 200, the control unit 130 of the control device 100 can obtain the identification code 220 of the luminaire 200. In one embodiment, the identification code 220 may be a bar code, a Quick Response matrix code (QR code), or other suitable indicia disposed on the housing of the light fixture 200. The user reads the identification code 220 on the lamp 200 by using a code reader or a camera of the mobile device, and then transmits the identification code 220 to the control device 100 by wireless transmission or wired transmission. In another embodiment, the identification code 220 may be manually input, and the identification code 220 is transmitted to the control device 100 by wireless transmission or wired transmission, but the invention is not limited thereto.
In the present embodiment, the control unit 130 may include at least one set of light color change control parameter table 134 and at least one lamp identification code 132. The identification codes 220 of the lamps 200 conform to one of the lamp identification codes 132, and one of the light color change control parameter tables 134 corresponds to the identification code 220 of the lamp 200. That is, after the control device 100 obtains the identification codes 220 of the lamps 200, the control unit 130 first determines whether the identification code 220 of the lamp 200 is the same as one of the lamp identification codes 132. If so, the control unit 130 finds the set of light color change control parameter tables 134 corresponding to the identification codes 220 of the lamps 200. The control unit 130 controls the driving unit 120 to output a driving signal according to the light color change control parameter table 134, so as to control the light color and the light emitting intensity of the lamp 200. Otherwise, if not, the control device 100 may not perform any signal regulation and control, so that the lamp 200 emits light with the preset light color; alternatively, the control device 100 controls the light color and the light emitting intensity of the lamp 200 in other manners.
In the present embodiment, the light color change control parameter table 134 is calculated according to the spectrum data of the lamp 200. In brief, the spectral data of each set of the color components 210 of each lamp 200 is obtained by a measuring device such as a colorimeter, a spectrophotometer, or an image photometer, and then the color variation region of the lamp 200 under a chromaticity coordinate system (i.e., the range of the light color that the lamp 200 can generate) is calculated through the spectral data. The chromaticity coordinate system may be CIE 1926, CIE 1931, CIE 1960, CIE 1964, or CIE 1976. Then, the lamp manufacturer can select a plurality of chromaticity coordinate points, blackbody radiation color temperature lines or isotherms in the light color change region as parameters in the light color change control parameter table 134. That is, each set of light color change control parameter table 134 is only applicable to the corresponding luminaire 200, otherwise the luminaire 200 cannot control the correct light color through the control device 100. Since the control device 100 of the embodiment of the invention utilizes the light color change control parameter table to regulate and control the light colors of the lamp 200, the lamp 200 can effectively maintain the light colors consistent.
In this embodiment, the driving signal may be an analog signal, such as a current signal or a voltage signal. Alternatively, the driving signal may be a digital signal, such as a Pulse Width Modulation (PWM) signal, a Leading Edge (LE) Modulation signal, a Trailing Edge (TE) Modulation signal, or a combination of the above analog signal and digital signal. However, the invention is not limited thereto, and other suitable signal modes are also included in the scope of the invention.
In an embodiment, the control unit 130 can also directly adjust the light emitting intensity of each set of the light color elements 210 through the driving unit 120, so that the lamp 200 emits light of a specific light color. That is, the control unit 130 of the control device 100 can regulate the light color of the luminaire 200 without going through the light color change control parameter table 134. For example, the user may use an application provided by the luminaire producer to adjust the light color of the luminaire 200. The application program has an interface for adjusting the light intensity of each set of light color elements 210 of the luminaire 200. Furthermore, the application program may be installed in a Personal Computer (PC), a notebook computer, a mobile device, or a smart phone, and transmit a signal to the control device 100 by wireless transmission or wired transmission. Since the control unit 130 of the control device 100 according to the embodiment of the present invention can also directly adjust the light emitting intensity of the light color element 210, a user can adjust the required light color of the lamp according to the usage situation, which is more convenient for the user.
In addition to the above-mentioned controlling the light color of the lamp 200 by using the light color change control parameter table 134, or directly adjusting the light emitting intensity of the light color element 210 by the control unit 130, the control unit 130 of the embodiment of the present invention can also perform more precise control on the light color of the lamp 200 according to the user's requirement. Fig. 2 is a schematic diagram illustrating a control device according to an embodiment of the invention calculating a light color change region of a lamp according to spectrum data of a light color element of the lamp. Referring to fig. 1 and 2, for convenience of description, fig. 2 omits the connection unit 110 and the driving unit 120 of fig. 1. In this embodiment, the control unit 130 can also calculate the light color changing region R of the lamp 200 according to the spectrum data of the plurality of sets of light color elements 210 of the lamp 200. The control unit 130 controls the driving unit 120 to output the driving signal according to the light color changing region R.
In detail, in the present embodiment, the control unit 130 may include the spectral data 136 of the plurality of sets of photochromic elements 210. After the control unit 130 obtains the identification code 220 of the lamp 200, the control unit 130 finds the spectrum data 136 corresponding to the identification code 220. As shown in fig. 2, the luminaire 200 has, for example, three sets of photochromic elements 210 of different light colors. The control unit 130 calculates a chromaticity coordinate point A, B, C of the color filter 210 in the chromaticity coordinate system 310 from the spectrum data 136. The chromaticity coordinate system 310 may be CIE 1926, CIE 1931, CIE 1960, CIE 1964, or CIE 1976, but the present invention is not limited thereto. The color change region R of the lamp 200 is a region formed between the chromaticity coordinate points A, B, C, such as line segments L1, L2, L3 and an area AR. Therefore, the light color generated by the lamp 200 may fall within the light color change region R. Moreover, the user can use the application program to control the light color of the lamp 200. The interface of the application is, for example, the usage interface 300 in fig. 2. Therefore, the user can specify the desired chromaticity coordinate point, such as chromaticity coordinate point D, as desired. The control unit 130 calculates a driving signal corresponding to the chromaticity coordinate point D, and controls the driving unit 120 to output the driving signal, so that the lamp 200 emits light with a color corresponding to the light color. Since the control device 100 of the embodiment of the present invention also allows the user to specify the desired light color, so that the lamp 200 can generate the light color in a more precise manner, the control device 100 of the embodiment of the present invention can also meet the use requirements of professional lighting users.
Furthermore, the spectrum data 136 is built in the control unit 130 as an example, but the invention is not limited thereto. In one embodiment, the spectral data 136 may also be input to the control unit 130 via wireless or wired transmission. This is the case, for example, when the control unit 130 cannot identify the identification code 220 of the luminaire 200, or the light color component 210 of the luminaire 200 is attenuated and the spectral data 136 needs to be updated. Accordingly, the user may input the spectral data 136 to the control unit 130 as desired.
In addition, the control Unit 130 includes, for example, a Micro Controller Unit (MCU), a Central Processing Unit (CPU), a microprocessor (microprocessor), a Digital Signal Processor (DSP), a programmable controller, a Programmable Logic Device (PLD), or other similar devices or combinations thereof, and the invention is not limited thereto. Thus, in an embodiment, the driving unit 120 may be a part of the control unit 130. In addition, in one embodiment, the functions of the control unit 130 may be implemented as a plurality of program codes. These program codes are stored in a memory and executed by the control unit 130. Alternatively, in one embodiment, the functions of the control unit 130 may be implemented as one or more circuits. The present invention is not limited to the implementation of the functions of the control unit 130 in software or hardware. Furthermore, the lamp identification code 132, the light color change control parameter table 134 or the spectrum data 136 may be stored in the control unit 130, which is not limited in the present invention.
Fig. 3 is a schematic diagram of the control device according to the embodiment of the present invention, in which the connection unit is an adaptor. Referring to fig. 3, in the present embodiment, the connection unit 110 of the control device 100 is an adapter 112. The adaptor 112 is connected to the power input 230 of the lamp 200. The adapter 112 in fig. 3 is exemplified by a usb adapter, but the invention is not limited thereto, and the adapter 112 may also be an AC adapter, a DC adapter or other suitable adapters. Since the control device 100 of the embodiment of the present invention uses the adaptor 112 to electrically connect with the lamp 200, the control device 100 can be a "plug and play" light color control device of the lamp. Compared with the prior art in which different control devices are designed for different lamps in the market, the control device 100 of the embodiment of the present invention is more convenient for users.
In one embodiment, the control device 100 can be built in the luminaire 200. That is, the luminaire producer can set the control device 100 of the embodiment of the present invention in the luminaire when producing the luminaire 200. Therefore, the lamp manufacturer can simply produce the lamp 200 with variable light color without designing other light color control devices. For the lamp producer, the control device 100 of the embodiment of the invention can also save development and production costs and reduce development and production time.
In summary, the control device of the embodiment of the invention is electrically connected to the lamp through the connection unit, and the control unit can control the lamp to emit light with variable light color after recognizing the specification of the lamp. Moreover, the lamp producer can produce the lamp with variable light color without additionally designing other light color control devices. It is also possible for lamp manufacturers to save development and production costs and reduce development and production time.
