Detailed Description
Fig. 1 is a schematic block diagram of a lamp testing apparatus according to an embodiment of the invention. Referring to fig. 1, the lamp testing apparatus 100 according to the embodiment of the invention can test the spectrum data of each photochromic element 210 of a lamp 200 and calculate the photochromic change control parameter table of the lamp 200 according to the spectrum data. The lamp testing device 100 then inputs the light color change control parameter table into the lamp 200, so that the lamp 200 can emit the corresponding light color according to the light color change control parameter table. Moreover, the lamp testing device 100 can further verify whether the light color emitted by the lamp 200 falls within the error range, so as to confirm the light quality of the lamp 200. The lamp testing apparatus 100 according to the embodiment of the present invention will be described in detail below.
In the present embodiment, the lamp testing device 100 includes a driving unit 110, a testing unit 120, an operation unit 130, and an input unit 140, wherein the testing unit 120 is electrically connected to the driving unit 110, the operation unit 130 is electrically connected to the testing unit 120, and the input unit 140 is electrically connected to the operation unit 130.
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, blue, and white light emitting diodes.
In the present embodiment, the driving unit 110 sends the driving signal in a wireless transmission manner or a wired transmission manner to drive the lamp 200 to sequentially turn on the plurality of color elements 210 in the lamp 200. While the photochromic elements 210 in the lamp 200 are turned on, the testing unit 120 is configured to test the plurality of sets of photochromic elements 210 of the lamp 200, so as to sequentially obtain the spectral data of each set of photochromic elements 210. The wireless transmission mode includes ZigBee, Bluetooth (Bluetooth), Digital Addressable Lighting Interface (DALI), or Wi-Fi, but the invention is not limited thereto. Furthermore, in order to verify the accuracy of the light quality of the lamp 200, the driving unit 110 drives the lamp 200 to turn on the maximum light emitting intensity of the photochromic element 210, but the invention is not limited thereto.
In one embodiment, the lamp testing apparatus 100 further includes a temperature controller. The driving unit 110 can drive the temperature controller to regulate and control the temperature of the environment where the lamp 200 is used. When the usage environment of the lamp 200 reaches a specific temperature or working temperature (working temperature), the driving unit 110 drives the lamp 200 to sequentially turn on the light color elements 210 of the lamp 200. The specific temperature or operating temperature may be a temperature at which the photochromic element 210 stably emits light, such as 20 to 30 ℃, and preferably 25 ℃. However, the present invention is not limited thereto, and the specific temperature or the operating temperature is determined according to the device characteristics of the photochromic device 210. In another embodiment, the lamp testing device 100 may include a temperature sensor. The driving unit 110 can also drive the lamp 200 to start a set of photochromic elements 210 first, and drive the temperature sensor to measure the temperature of the lamp 200. The testing unit 120 starts testing the photochromic element 210 of the lamp 200 only when the lamp 200 reaches a specific temperature. Since the lamp testing device 100 of the embodiment of the invention has the temperature controller or the temperature sensor, the lamp producer can master the light emitting quality of the lamp 200 at different temperatures.
In the present embodiment, when the temperature of the usage environment of the lamp 200 or the temperature of the lamp reaches a desired temperature, the lamp manufacturer uses the testing unit 120 to obtain a plurality of sets of spectral data of the lamp 200 by using a colorimeter, a spectral luminance meter or an image-based luminance meter. The light colorimeter is, for example, a light intensity measuring instrument having red, green and blue filters, and thus the tristimulus values X, Y and Z of the lamp 200 can be obtained by using the light colorimeter. The spectral luminance meter is, for example, a light intensity measuring instrument having a plurality of filters, and includes at least red, green, and blue filters. Alternatively, the spectrophotometer may use a grating to obtain the spectrum of the luminaire 200. Therefore, more complete spectral data can be obtained by using the spectral luminance meter. The image luminance meter is, for example, an image sensor (e.g., CCD) having at least red, green, and blue filters. When the lamp testing apparatus 100 uses the image-type luminance meter to obtain the spectrum data of the lamps 200, since the image-type luminance meter can obtain the spectrum in space, the lamp testing apparatus 100 can simultaneously test a plurality of lamps 200, and the lamp testing apparatus 100 can further shorten the testing time and the subsequent verification time. Therefore, the lamp testing device 100 can reduce the production time of the lamp. However, the method of acquiring the spectral data of the lamp 200 according to the present invention is not limited to the above-described colorimeter, spectral luminance meter, or image-based luminance meter.
After obtaining the spectrum data of the lamp 200, the operation unit 130 of the embodiment calculates the light color change control parameter table of the lamp 200 according to the plurality of sets of spectrum data. Specifically, the operation unit converts each set of spectral data into a chromaticity coordinate point of a chromaticity coordinate system. Such a system of chromaticity coordinates may be CIE 1926, CIE 1931, CIE 1960, CIE 1964, CIE 1976, or other suitable system of chromaticity coordinates. The light color elements 210 with different light colors are respectively different chromaticity coordinate points. A light color changing area can be formed among the chromaticity coordinate points. For example, the light color changing area formed by the two chromaticity coordinates is a line segment. And so on, the light color change area formed by the three chromaticity coordinate points is a triangular area. Therefore, the light color generated by the lamp 200 falls within the light color changing region.
Next, the operation unit 130 of the present embodiment calculates the light color change control parameter table of the lamp 200 according to the light color change area. The parameters and the number of the parameters in the light color change control parameter table are determined according to actual requirements. For example, the light color change control parameter table may include (warm) white light corresponding to a color temperature of 3500K, (neutral) white light corresponding to a color temperature of 5000K, (cold) white light corresponding to a color temperature of 6500K, or light of other light colors, but the invention is not limited thereto. In addition, the parameters in the light color change control parameter table may be determined according to the signal mode of the lamp 200 controlling light emission, and may be digital parameters, analog parameters, or a combination thereof.
After the operation unit 130 calculates the light color change control parameter table of the lamp 200, in the present embodiment, the input unit 140 inputs the light color change control parameter table into the control unit 220 of the lamp 200 in a wireless transmission or wired transmission manner. Therefore, the lamp 200 can emit light corresponding to the light color according to the light color change control parameter table in the control unit 220. Since the transmission mode of the lamp testing device 100 of the embodiment of the invention can select wireless transmission or wired transmission, it is more convenient for lamp manufacturers.
The control Unit 220 includes, for example, a Micro Controller Unit (MCU), a single crystal Microcontroller, 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, which are not limited in the present invention. In addition, in one embodiment, the functions of the control unit may be implemented as a plurality of program codes. These program codes are stored in a memory and executed by the control unit 220. Alternatively, in one embodiment, the functions of the control unit 220 may be implemented as one or more circuits. The present invention is not limited to the implementation of the functions of the control unit 220 in software or hardware.
In addition, in order to verify the light emitting quality of the lamp 200, the driving unit 110 of the embodiment drives the lamp 200 to sequentially emit a plurality of sets of lights corresponding to the light colors according to the light color change control parameter table. The lamp testing apparatus 100 obtains a plurality of sets of spectra and chromaticities (chromaticities) of light corresponding to the light colors through the testing unit 120. For example, if the light color change control parameter table includes the white light with the corresponding color temperature of 3500K, the white light with the corresponding color temperature of 5000K, the white light with the corresponding color temperature of 6000K and other light colors, the driving unit 110 drives the lamp 200 to sequentially emit light according to the light colors recorded by the light color change control parameter table. Meanwhile, the test unit 120 tests a spectrum of light corresponding to the light color.
In the present embodiment, the operation unit 130 verifies whether the spectrums of the light with the plurality of corresponding colors fall within an error range. The error range is, for example, an error range in a chromaticity coordinate system. That is, the operation unit 130 converts the spectrum of the light corresponding to the light color into a chromaticity coordinate point of the chromaticity coordinate system, and then compares whether the difference between the chromaticity coordinate point and the chromaticity coordinate point represented by the light color change control parameter table falls within the error range.
In the present embodiment, when the spectra of the light of the plurality of sets of corresponding colors do not fall within the error range, the operation unit 130 performs the plurality of sets of difference analysis. The difference analysis includes a difference analysis of color difference (color difference) and color tolerance (SDCM), an absolute luminance (photometry) abnormality analysis, a color rendering index (color rendering index) abnormality analysis, and a difference analysis of spectral light color and luminance before and after driving of the lamp 200 or a difference of ambient temperature. The color rendering index includes CRI, CQS, GAI, IES TM30-15, TLCI or TLMF, but the invention is not limited thereto. Further, the difference between the spectral color and the brightness before and after the lamp 200 is driven or after a period of time, for example, the difference between the spectral color and the brightness when the lamp 200 is turned on and after the lamp is used for a period of time. Alternatively, the spectral color and brightness difference between the lamp 200 being turned on and the lamp 200 operating at some specific temperature is analyzed. Alternatively, the lamp 200 is adjusted to a certain temperature, the light spectrum of the lamp 200 is sequentially tested, and the light color and brightness of the light spectrum of the lamp 200 at different temperatures are analyzed. Since the lamp testing device 100 of the embodiment of the invention can further verify the light-emitting quality of the lamp 200, a lamp producer can perform quality screening and control on lamps 200 with different light-emitting qualities.
In addition, the lighting fixture testing apparatus 100 of the present embodiment is configured in, for example, a Personal Computer (PC) operating system, an Android operating system, an iOS operating system, or a microcontroller system, wherein each unit of the lighting fixture testing apparatus 100 can implement the function of each unit through one or more microcontrollers, and all units can be integrated into one unit controlled by a single module or part of units can be integrated into the same module. Therefore, when the lamp testing device 100 is configured on a pc operating system, an android operating system or an iOS operating system, a lamp manufacturer can operate the lamp testing device 100 through a pc, a laptop, a mobile device or a smart phone in a wired transmission or a wireless transmission manner. Furthermore, when the lamp testing device 100 is configured on a microcontroller system, a lamp manufacturer can operate the lamp testing device 100 through a touch screen or a key device or other suitable operation interface. Since the lamp testing device 100 of the embodiment of the invention can be configured in a personal computer operating system, an android operating system, an iOS operating system or a microcontroller system, and a lamp producer can use the lamp testing device according to the use habit, the lamp testing device 100 of the embodiment of the invention is more convenient.

Referring to fig. 2, a method for using the lamp testing device 100 according to an embodiment of the invention includes the following steps. A driving signal is sent out to drive a lamp 200 to sequentially turn on multiple sets of photochromic elements 210 in the lamp 200, step S100. The spectrum data of each set of the color elements 210 is obtained, step S120. A light color change control parameter table of the lamp 200 is calculated according to the plurality of sets of spectral data, and step S140. The light color change control parameter table is input into the control unit 220 of the lamp 200, step S160. And verifying the light emitting quality of the lamp 200, step S180.
Fig. 3 is a flowchart of a method of verifying light quality of a luminaire. Referring to fig. 3, in an embodiment of the invention, the method for verifying the light-emitting quality of the lamp 200 includes the following steps. The lamp 200 is driven to sequentially emit a plurality of sets of lights corresponding to the light colors according to the light color change control parameter table, so as to obtain a plurality of sets of spectra and chromaticities of the lights corresponding to the light colors, step S200. And verifying whether the spectrums of the light with the multiple groups of corresponding light colors fall within an error range. When the spectra of the light with the multiple sets of corresponding light colors do not fall within the error range, a multiple-set difference analysis is performed, step S220.
