Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular to a lighting system. Background Art

[0002] TL84 light source is a typical warm white light source, with a color temperature of about 4000K. The color rendering index (CRI) of this light source is usually between 80 and 90, which can provide good color reproduction and comfort. Due to its soft warm white light, TL84 light source is often used in home lighting, reading lights and decorative lighting to create a warm and comfortable atmosphere. In addition, TL84 light source also has high luminous efficiency and long service life, which makes it widely used in commercial lighting and display lighting. For example, TL84 light source is also mainly used in stores and office environments in Europe and the Pacific Rim. At present, Europe and Japan usually specify TL84 as the primary light source for color matching.

[0003] The current TL83, TL84, and U30 light sources all use high voltage to excite mercury, which in turn excites the phosphor on the inner wall of the tube to emit light. Since the ultraviolet component of mercury ions is relatively strong, the current TL83 and TL84 lamps have a short lifespan. In addition, due to problems with the traditional manufacturing process, the current TL83 and TL84 lamps are too large, and the phosphor mixing ratio of traditional TL83 and TL84 lamps is fixed, making it impossible to perform spectral modulation.

[0004] The existing TL84 light source is a fluorescent lamp, and its light-emitting principle determines that its life is relatively short. Fluorescent lamps use electric current to excite phosphors to emit light, and the service life of phosphors is limited. When the TL84 light source is used for about 2,000 hours, its color temperature, color rendering index and brightness begin to gradually decrease. At this time, although the lamp can still light up, it is no longer suitable for use as a standard light source because its representation of the color of objects is no longer accurate.

[0005] At present, in the field of precision processing in automated factories, the requirements for lighting sources are becoming more and more stringent. For example, in the assembly and processing of mobile phone camera film groups and chip assembly and processing, the use of light sources not only affects the accuracy of processing, but also affects the life of the processed products. The current TL84 light source uses fluorescent lamps, which have a short service life and are easy to damage the processed products in certain processing fields. For example, during chip assembly and processing, since the fluorescent lamp excites the phosphor to emit light through electric current, the wavelength range of the light it emits overlaps with the wavelength range of the light used for chip etching, which can easily cause damage to the wafer.

[0044] See also Figure 1 and Figure 2The embodiment of the present application provides a lighting system 100, which includes a main body 10, a light guide component 12, and a first light component 13. The main body 10 includes a mounting cavity 105 and a light outlet 106 connected to the mounting cavity 105. The light guide component 12 is coupled to the main body 10 and is used to seal the light outlet 106. The first light component 13 is coupled to the main body 10 and is used to emit light toward the mounting cavity 105. The filter plate 123 is coupled to the mounting cavity 105 and is located on a side of the light guide component 12 away from the light outlet 106.

[0045] It can be understood that, during the specific operation of the lighting system 100 , the first light assembly 13 can emit light, and the light is transmitted to the outside through the light guide assembly 12 , so that the lighting system 100 can achieve the lighting function.

[0046] Specifically, the first lighting assembly 13 includes first channel lamp beads, second channel lamp beads and third channel lamp beads. The wavelength range of the light emitted by the first channel lamp beads is 602nm-612nm, the wavelength of the light emitted by the second channel lamp beads is 445nm-455nm, and the wavelength of the light emitted by the third channel lamp beads is 540nm-550nm. The first channel lamp beads, the second channel lamp beads and the third channel lamp beads are respectively controlled by the first channel circuit, the second channel circuit and the third channel circuit. The first channel circuit, the second channel circuit and the third channel circuit are used to adjust the brightness of the lamp beads to meet the TL84 spectrum standard.

[0047] It is understood that in this application, the first channel lamp beads, the second channel lamp beads and the third channel lamp beads are all LED lamps, and refer to Figure 6 In the spectrum diagram of the TL84 light source shown, the three wavelengths of 445nm-455nm, 540nm-550nm and 602nm-6nm correspond to the three peak ranges in the spectrum diagram of the TL84 light source. That is to say, the lighting system 100 of the present application includes replacing the existing Tl84 fluorescent lamp with an LED, and emitting light of mixed wavelengths through the synergistic effect of the first channel lamp beads, the second channel lamp beads and the third channel lamp beads to ensure that the spectrum of the filtered light is similar to the spectrum of the Tl84 light source, so that the lighting system 100 realizes the light illumination function of the TL84 spectrum. In addition, the lighting system 100 in the embodiment of the present application uses LED excitation to reduce the energy of ultraviolet light, so the life span is more than ten times that of the existing high-pressure mercury lamp. In the embodiment of the present application, the lighting system 100 uses a multi-channel circuit control and adjustment, and the spectral component and range can be adjusted by adjusting the power of the light-emitting chip. The color temperature standard of the TL84 light source is 4000±200K. Through multi-channel adjustment and calibration, the color temperature deviation of the light source can be accurately controlled at zero K.

[0048] Furthermore, the filter plate 123 is used to filter light waves of a preset wavelength L, and the preset wavelength L satisfies the condition: L<400nm.

[0049] It can be understood that the filter plate 123 can filter out light with a wavelength below 400nm, so as to eliminate the ultraviolet light portion in the mixed wavelength light emitted by the first channel lamp beads, the second channel lamp beads and the third channel lamp beads, that is, eliminate the ultraviolet light portion in the TL84 spectrum, thereby increasing the life of the lighting system 100 itself, and during the use of the lighting system 100, it also reduces the damage of ultraviolet light to the life of the processed product itself.

[0050] Specifically, during the specific operation of the lighting system 100, by simultaneously controlling the first channel lamp beads, the second channel lamp beads and the third channel lamp beads to start, the mixed wavelength light emitted by the first channel lamp beads, the second channel lamp beads and the third channel lamp beads can emit light of the TL84 spectrum after filtering the light waves with a preset wavelength L less than 400nm through the filter plate 123, and further the light of the TL84 spectrum is transmitted to the outside through the second light assembly 14 and the light-transmitting plate 121 of the lighting system 100 to emit a blue light source similar to daylight to achieve lighting, and the color temperature of the blue light source is 4000K. In this way, the lighting system 100 provided in the embodiment of the present application can emit light of the TL84 spectrum with a higher color rendering index, and can be used for color matching to provide better color reproduction.

[0051] It should be noted that the specific value range of the preset wavelength L is obtained through experimental tests, and the parameters, steps, etc. related to the experimental tests of the specific value range of the preset wavelength L are conventional techniques of those skilled in the art and will not be elaborated here.

[0052] The specific structures of the first channel lamp beads, the second channel lamp beads and the third channel lamp beads are not limited. In some embodiments, not shown, the first channel lamp beads include a 365nm light-emitting chip and a red phosphor with a wavelength of 602nm-6nm. Since the first channel lamp beads are used to emit monochromatic red light, a UV chip with a wavelength of 365n is used to excite the red phosphor with a peak wavelength of 602nm-6nm, thereby ensuring that the second channel lamp beads can form a monochromatic red fluorescence that coincides with the Tl84 spectrum, that is, the peak position and peak shape of the luminescent spectrum of the monochromatic red fluorescence coincide with the Tl84 spectrum, so as to realize the Tl84 standard light source.

[0053] Correspondingly, the second channel lamp beads include a 365nm light-emitting chip and a blue phosphor with a wavelength of 445nm-455nm. Since the second channel lamp beads are used to emit monochromatic blue light, the ultraviolet light chip with a wavelength of 365nm is used to excite the blue phosphor with a peak wavelength of 445nm-455nm, thereby ensuring that the second channel lamp beads can form a monochromatic blue fluorescence that coincides with the Tl84 spectrum, that is, the peak position and peak shape of the luminous spectrum of the monochromatic blue fluorescence coincide with the Tl84 spectrum, so as to realize the Tl84 standard light source.

[0054] Correspondingly, the third channel lamp beads include a 365nm light-emitting chip and a green phosphor with a wavelength of 540-550nm. Since the third channel lamp beads are used to emit monochromatic green light, the ultraviolet light chip with a wavelength of 365nm is used to excite the green phosphor with a peak wavelength of 540-550nm, thereby ensuring that the excitation forms a monochromatic green fluorescence that coincides with the Tl84 spectrum, that is, the peak position and peak shape of the luminescent spectrum of the monochromatic green fluorescence coincide with the Tl84 spectrum, so as to realize the Tl84 standard light source.

[0055] It is understandable that the 365nm light-emitting chips in the first channel lamp beads, the second channel lamp beads and the third channel lamp beads can also use 200nm light-emitting chips and 300nm light-emitting chips, and the wavelength range of the light-emitting chips is 200nm-365nm.

[0056] It can be understood that during the specific operation of the lighting system 100, the filter plate 123 can filter out light with a wavelength below 400nm, thereby effectively removing the 365nm ultraviolet light emitted by the light-emitting chip. In this way, the peak positions and peak shapes of the luminous spectra of the monochromatic red fluorescence formed by the first channel lamp beads, the monochromatic blue fluorescence formed by the second channel lamp beads, and the monochromatic green fluorescence formed by the third channel lamp beads can all overlap with the Tl84 spectrum, so that the lighting system 100 can achieve the lighting function of the Tl84 standard light source, and can reduce the damage of ultraviolet light to the life of the lighting system 100 itself and the processed products during the use of the lighting system 100.

[0057] In other embodiments, not shown in the figure, the first channel lamp bead includes a 365nm light-emitting chip and a red phosphor with a wavelength of 602nm-6nm, the second channel lamp bead includes a 445nm-455nm blue light chip, and the third channel lamp bead includes a 365nm light-emitting chip and a green phosphor with a wavelength of 540-550nm.

[0058] It can be understood that the second channel lamp bead uses a 445nm-455nm blue light chip with a simple structure, and the blue light chip can emit monochromatic blue light that coincides with the Tl84 spectrum, reducing the amount of ultraviolet light in the lighting system 100, thereby reducing the damage of ultraviolet light to the lighting system 100 itself and the life of the processed products during the use of the lighting system 100.

[0059] For some examples, see Figure 1 and Figure 2 The first lighting component 13 is matched in the installation cavity 105 and is arranged around the side wall of the installation cavity 105 . The first lighting component 13 surrounds the filter plate 123 .

[0060] It is understandable that, during the specific operation of the lighting system 100, the first light assembly 13 can emit light toward the filter plate 123, and the light will be transmitted to the outside through the filter plate 123 and the light guide assembly 12, so that the lighting system 100 can achieve the lighting function. Among them, the filter plate 123 can filter out the light with a wavelength below 400nm, so as to remove the ultraviolet light part of the mixed wavelength light emitted by the first channel lamp beads, the second channel lamp beads and the third channel lamp beads, that is, to remove the ultraviolet light part of the TL84 spectrum, thereby increasing the life of the lighting system 100 itself, and during the use of the lighting system 100, it also reduces the damage of ultraviolet light to the life of the processed product itself.

[0061] For some examples, see Figure 3 The first lighting component 13 is matched in the installation cavity 105 and is disposed on the bottom wall of the installation cavity 105 , and the first lighting component 13 is aligned with the light outlet 106 .

[0062] It is understandable that, during the specific operation of the lighting system 100, the first light assembly 13 can emit light toward the light outlet 106, and the light will be transmitted to the outside through the filter plate 123 and the light guide assembly 12, so that the lighting system 100 can achieve the lighting function. In other words, during the specific operation of the lighting system 100, the propagation path of the light is: light guide assembly 12-installation cavity 105-filter plate 123-light guide assembly 12-outside.

[0063] For some examples, see Figure 4 The lighting system 100 further includes a connecting assembly 16, the connecting assembly 16 includes a housing 161, and a light-emitting cavity 162 connected between the housing 161 and the main body, the housing 161 is formed with a light-emitting cavity 162, and a light-transmitting member 163 is connected therebetween;

[0064] The first light assembly 13 is mounted in the light emitting cavity 162 .

[0065] It can be understood that during the specific operation of the lighting system 100, the first lighting component 13 will emit light into the light-emitting cavity 162, and the light-transmitting component 163 can transmit the light in the light-emitting cavity 162 to the installation cavity 105. After entering the installation cavity 105, the light will be transmitted to the outside through the filter plate 123 and the light guide component 12 in turn, so that the lighting system 100 can realize the lighting function.

[0066] In some embodiments, the light transmitting member 163 is an optical fiber. It is understandable that the optical fiber has a better light guiding effect and has a smaller loss of light, which is beneficial to cost saving. At the same time, the manufacturing of the optical fiber is simple and cheap, which is beneficial to cost saving. That is to say, in the specific operation process of the lighting system 100, the propagation path of the light is: light guide component 12-light emitting cavity 162-optical fiber-installation cavity 105-filter plate 123-light guide component 12-external environment.

[0067] In some other embodiments, a light channel 164 is formed in the light transmitting member 163 for connecting the light emitting cavity 162 and the mounting cavity 105. The first light assembly 13 is matched in the light emitting cavity 162 and is aligned with the opening of the light channel 164 for connecting the light emitting cavity 162.

[0068] It is understandable that, during the specific operation of the lighting system 100, the light emitted by the first light assembly 13 is transmitted from the light-emitting cavity 162 to the light-emitting channel 164, then enters the installation cavity 105 through the light-emitting channel 164, and then sequentially passes through the filter plate 123 and the light guide assembly 12 to the outside, so that the lighting system 100 can achieve the lighting function. In other words, during the specific operation of the lighting system 100, the propagation path of the light is: light guide assembly 12-light-emitting cavity 162-light-emitting channel 164-installation cavity 105-filter plate 123-light guide assembly 12-outside.

[0069] For some examples, see Figure 4 The lighting system 100 further includes a light blocking member 15, which is matched in the installation cavity, and the light blocking member 15 and the light emitting channel 164 are arranged at intervals to communicate with the opening of the installation cavity.

[0070] It is understandable that, during the specific operation of the lighting system 100, the light emitted by the first light assembly 13 will be transmitted from the light-emitting cavity 162 to the light-emitting channel 164, and then enter the installation cavity 105 through the light-emitting channel 164. After entering the installation cavity 105, the light will be irradiated on the light-blocking member 15, and will be continuously refracted under the action of the light-blocking member 15, so that the light is evenly transmitted in the installation cavity 105, and further transmitted to the outside through the filter plate 123 and the light guide assembly 12, so that the lighting system 100 can achieve the lighting function. In other words, during the specific operation of the lighting system 100, the propagation path of the light is: light guide assembly 12-light-emitting cavity 162-light-emitting channel 164-light-blocking member 15-installation cavity 105-filter plate 123-light guide assembly 12-outside.

[0071] The lighting system 100 provided in the embodiment of the present application can guide and change the propagation direction of the light emitted by the first light component 13 in the installation cavity 105 through the light blocking member 15, and enable the light emitted by the first light component 13 to propagate as much as possible toward the filter plate 123 and the light guide component 12, and can achieve a better uniform light transmission effect.

[0072] For some examples, see Figure 5 A mounting portion 107 is protruded from the inner wall of the end portion of the main body 10 close to the light outlet 106 , and the mounting portion 107 surrounds the light outlet 106 .

[0073] The first lighting assembly 13 is matched to the surface of the mounting portion 107 facing the mounting cavity 105 .

[0074] During the specific operation of the lighting system 100, the light emitting component 12 can emit light toward the installation cavity 105. The light emitted by the light emitting component 12 is irradiated on the inner wall of the installation cavity 105 and is continuously refracted, so that the light is evenly transmitted in the installation cavity 105 and further guided out to the outside through the filter plate 123 and the light guide component 12.

[0075] In some embodiments, not shown, the lighting system 100 further includes a reflector, which is coated on the inner wall of the mounting cavity. It is understandable that the reflector can effectively increase the light reflectivity of the inner wall of the mounting cavity 105, thereby reducing the loss of light during the reflection process to achieve a better uniform light transmission effect.

[0076] Furthermore, the reflector is also coated on the light blocking member 15. In this way, after the light enters the installation cavity 105, it will be irradiated on the light blocking member 15, and will be continuously refracted under the action of the light blocking member 15. The reflector can effectively increase the light reflectivity of the light blocking member 15, thereby reducing the loss of light in the reflection process, so that the light blocking member 15 can transmit as much light as possible emitted by the first light assembly 13 toward the filter plate 123 and the light guide assembly 12, and can achieve a better uniform light transmission effect.

[0077] The specific style of the reflective element is not limited. In some embodiments, the reflective element is a film coated on the inner wall of the installation cavity 105 with a reflective material.

[0078] In other embodiments, the reflective element is a prefabricated reflective film made of reflective material. It is understandable that the reflective element is a prefabricated reflective film made of reflective material, which is conducive to rapid assembly, convenient replacement and maintenance, and saves manufacturing time and cost.

[0079] The specific type of the reflective material is not limited, for example, the reflective material is polycarbonate, acrylic, chlorinated rubber, etc.

[0080] In some embodiments, the reflective material in the reflective element is nano-scale particles. It is understood that the nano-scale particles can be understood as particles with a size of 200 nm.

[0081] In the present application, the reflective film made of reflective material with nano-scale particles has the advantages of dense film layer and good film uniformity, so as to increase the reflectivity of light, thereby effectively reducing the loss of light and improving the brightness of light transmission.

[0082] For some examples, see Figure 1 and Figure 2 The light guide assembly 12 also includes a light-transmitting plate 121 and a light guide plate 122. The light-transmitting plate 121 is connected to the main body 10 and is used to seal the light outlet 106. The light guide plate 122 is connected to the side of the light-transmitting plate 121 away from the light outlet 106. The filter plate 123 is located on the side of the light guide plate 122 away from the light-transmitting plate 121.

[0083] It is understandable that after the second light assembly 14 emits light toward the installation cavity 105, the light in the installation cavity 105 will be transmitted to the light guide plate 122, and the light entering the light guide plate 122 will be uniformly transmitted from the light guide plate 122 toward the surface of the light-transmitting plate 121, and further transmitted to the light-transmitting plate 121, and finally the light will be guided to the outside through the light-transmitting plate 121 to achieve the lighting or luminous function. In this way, the lighting system 100 provided by the present application can achieve uniform light transmission through the light guide plate 122, so that the light-transmitting plate 121 can transmit light uniformly, which is conducive to improving the lighting quality of the lighting system 100.

[0084] For some examples, see Figure 1 and Figure 2 The lighting system 100 further includes a second lighting component 14 , which is matched in the installation cavity 105 and disposed around the side wall of the installation cavity 105 , and the second lighting component 14 surrounds the periphery of the light guide plate 122 .

[0085] It is understandable that the second light assembly 14 and the second light assembly 14 can respectively emit light of different wavelengths, and the user can control the second light assembly 14 and any one of the second light assembly 14 to start according to the actual situation. After starting, the second light assembly 14 or the second light assembly 14 can emit light toward the installation cavity 105, and the light in the installation cavity 105 will be transmitted to the light guide plate 122. The light entering the light guide plate 122 will be uniformly transmitted from the light guide plate 122 toward the surface of the light-transmitting plate 121, and further transmitted to the light-transmitting plate 121, and finally the light will be guided to the outside through the light-transmitting plate 121 to achieve lighting or luminous functions. In this way, the lighting system 100 provided in the present application can achieve lighting of different lights by controlling the second light assembly 14 and the second light assembly 14, and can achieve specific lighting functions to meet the specific needs of users.

[0086] In some embodiments, not shown in the figure, the second lighting component 14 includes at least two channel lamp beads, the two channel lamp beads are respectively a fourth channel lamp bead and a fifth channel lamp bead, the fourth channel lamp bead is used to emit light with a color temperature of 3000K, and the fifth channel lamp bead realizes a D50 light source, the fourth channel lamp bead and the fifth channel lamp bead are respectively controlled by the fourth channel circuit and the fifth channel circuit, and the two channel lamp beads in the second lighting component 14 are selectively lit.

[0087] It is understandable that, in the specific operation process of the lighting system 100, by selectively controlling the fourth channel lamp bead or the fifth channel lamp bead to turn on, the lighting system 100 can emit light of different types or properties to flexibly meet the different usage requirements of users.

[0088] Specifically, when the four-channel lamp beads that control the light of 3000K color temperature are turned on, the light of 3000K color temperature can be transmitted to the outside through the light guide plate 122 and the light-transmitting plate 121 to emit a warm white light to achieve lighting. In this way, the light emitted by the lighting system 100 is close to the performance effect of sunlight, which can give users a warm feeling. It also has better visibility, making it easier for users to distinguish the color of objects and the surrounding environment under warm white light.

[0089] When the fifth channel lamp bead that controls the D50 light source is turned on, the light of the D50 light source can be transmitted to the outside through the light guide plate 122 and the light-transmitting plate 121 to emit a light with a color temperature of about 5000K to achieve lighting. This light is generally considered to be the standard color temperature of the printing industry, especially under the ICC standard. This light source provides a lighting condition similar to daytime, making the color of objects look relatively normal.

[0090] For some examples, see Figure 1 and Figure 2 The light guide assembly 12 further includes a reflector 124 , which is disposed on the side of the filter plate 123 facing away from the light guide plate 122 and is used to seal the installation cavity 105 .

[0091] It is understandable that when the first light assembly 13 is started, the light emitted by the first light assembly 13 will irradiate and be transmitted into the filter plate 123. The filter plate 123 can filter the light waves with a preset wavelength L in the light emitted by the first light assembly 13, and the filtered light will be transmitted from the surface facing the light guide plate 122 and transmitted into the light guide plate 122. The filtered light will be uniformly transmitted to the light-transmitting plate 121 through the light guide plate 122, and finally the light will be guided to the outside through the light-transmitting plate 121 to achieve the lighting or luminous function. Similarly, light will also be transmitted from the surface of the filter plate 123 away from the light guide plate 122, and the reflector 124 can reflect the light transmitted from the filter plate 123 back into the filter plate 123, and transmit it to the light guide plate 122 and the light-transmitting plate 121 again to achieve lighting.

[0092] When the second light assembly 14 is activated, the light emitted by the second light assembly 14 will illuminate and be transmitted into the light guide plate 122. The light entering the light guide plate 122 will be uniformly transmitted from the light guide plate 122 toward the surface of the light-transmitting plate 121, and further transmitted to the light-transmitting plate 121. Finally, the light will be guided to the outside through the light-transmitting plate 121 to achieve the lighting or luminous function. Similarly, light will also be transmitted from the surface of the light guide plate 122 away from the light-transmitting plate 121 and transmitted from the surface of the light guide plate 122 away from the light-transmitting plate 121 through the filter plate 123. The reflector 124 can reflect the light transmitted from the filter plate 123 back into the filter plate 123, and transmit it to the light guide plate 122 and the light-transmitting plate 121 again to achieve lighting.

[0093] In this way, the lighting system 100 provided in the embodiment of the present application can guide and change the propagation direction of the light transmitted in the installation cavity 105 by setting the reflector 124, so that the light transmitted in the installation cavity 105 is transmitted toward the light-transmitting plate 121 as much as possible, so as to effectively reduce the loss of light conduction, thereby better improving the light transmittance brightness of the lighting system 100.

[0094] In some embodiments, not shown, the light guide plate 122 is made by double-sided dotting process. It is understandable that the light guide plate 122 made by double-sided dotting process has good light guiding performance, can effectively reduce the loss of light conduction, and thus improve the light transmission brightness of the lighting system 100.

[0095] The specific material of the light guide is not limited. Optionally, the light guide can be made of plastic materials such as PC (polycarbonate), PMMA (polymethylmethacrylate), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene) by injection molding, and of course, it can also be made of glass.

[0096] Exemplarily, the light guide is made of ABS (Acrylonitrile Butadiene Styrene), which has high strength, good toughness, is easy to be thermoformed, and has good light guiding performance.

[0097] The specific style of the main body 1010 is not limited. In some embodiments, see Figure 1 and Figure 2 The main body 10 also includes a side plate 101, a cover plate 102 and a circuit board 103. The side plate 101 is surrounded to form a through installation space 104. The cover plate 102 is matched with one end of the side plate 101 and seals one side opening of the installation space 104 to form an installation cavity 105. The circuit board 103 is matched in the installation space 104 and is arranged at intervals on the side of the cover plate 102 facing the installation cavity 105. A cable space is formed on the side of the circuit board 103 close to the cover plate 102, and the installation cavity 105 and the light outlet 106 are formed on the side of the circuit board 103 away from the cover plate 102.

[0098] For some examples, see Figure 1 and Figure 2 The shape formed by the side panels 101 is not limited, such as round, square, etc.

[0099] In some embodiments, not shown, a plurality of wire grooves are provided on the surface of the circuit board 103 facing the cable space. In this way, the wire grooves can facilitate the laying of cables, thereby effectively improving the convenience of assembling the lighting system 100.

[0100] In some embodiments, such as Figure 7As shown, a control circuit structure diagram of a lighting system 100 is provided, wherein the control circuit includes a light source controller, the light source controller is connected to a computer, the computer controls the light source controller, a digital display output is set on the light source controller, and the light source controller controls a first light component 13 and a second light component 14 through a plurality of channel circuits. The first light component 13 and the second light component 14 are selectively lit.

[0101] The control circuit consists of AC and DC circuit modules, DCDC voltage regulator circuit modules, MCU, PC port communication module, constant current drive output module and LED light source board module. The AC and DC circuit module is a switching power supply. Its main function is to convert AC220V to DC24V to power the DC circuit module and the constant current drive output module. The DCDC voltage regulator circuit outputs DC5V to power the PC communication module. The DCDC voltage regulator circuit outputs DC3.3V to power the MCU. The MCU outputs a dimming PWM signal to the constant current drive output module. The constant current drive output module outputs current to the LED light source board module. The LED light source board module lights up and emits TL84 light. The usual driver is PWM driving MOS tube to output to LED light source board, while the constant current drive output module is composed of op amp, MOS tube, sampling resistor, feedback circuit. The input PWM control signal is converted into a level signal after 2nd order RC filtering. The level signal is connected to the positive input of the op amp, and compared with the main sampling resistor feedback connected to the positive input of the op amp to output the error signal to control the G pole of the MOS tube, thereby changing the output current and reaching a constant current to the LED light source board. The LED light source lamp board module is composed of multiple LED multi-channel series and parallel combinations, each channel is adjustable separately, so multi-channel constant current drive is adopted, and MCU needs to output multi-channel PWM control to complete. To realize the output of multi-channel PWM, STMicroelectronics STM32F103 or STM32F407 is used. The STM32F407 main frequency is 168Mhz and can output 16khz with a depth of 4000 levels for dimming. The op amp used in the constant current drive output module has a very low input offset voltage and an adjustable bias voltage, which can meet the low brightness adjustment requirements of the LED light source. The MOS tube in the constant current drive output module uses DTU 15N10, with a low internal resistance of 65mΩ, a peak current of 15A, and a withstand voltage of 100V. The sampled resistor in the constant current drive output module uses a 2512 package, a low temperature drift of ±50ppm / ℃, and a power of 2W. The PC port communication module uses an sp232 level conversion chip, and the MCU output TTL is converted into an RS232 signal that can be recognized by the PC end. The LED light source lamp board module samples a double-layer aluminum substrate or copper substrate. Good heat dissipation ensures the stability of the output light and extends the life of the LED.

[0102] In some embodiments, Figure 8As shown, the first lighting component 13 (LED light bar) can be packaged into a small-sized TL84 planar light source to meet the needs of different light source usage scenarios. Currently, the minimum package size of LED can be 035*0.2 mm. Figure 8 Comparison of lamp tube size and LED package size.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
