Among them, the light source component is composed of a multi-channel coupled light source. Considering the structure, heat dissipation and cost, most of the light source components are still at the stage of low-power output.
[0037] Based on this, the utility model provides a light source solution that can be applicable to LED devices with high-power output performance, and greatly improves heat dissipation performance and production efficiency while ensuring costs.
[0038] The light source scheme will be described in detail below.
[0039] See also Figure 1 The utility model provides a light source device 100, including: a base plate 9, a dimming module 101 and a light source module 102. The light source module 102 is arranged on the base plate 9, and the light source module 102 includes an LED component 103 and a lens component 104. The LED component 103 is used to provide a plurality of outgoing light source signals; the lens component 104 is arranged in the emission direction of the outgoing light source signal, and is used to screen the wavelength of the outgoing light source signal, obtain a coupled light signal of a preset band, and emit the coupled light signal in a preset direction. The power of the coupled light signal is the sum of the powers of each outgoing light source signal. The dimming module 101 is arranged in the propagation direction of the coupled light signal, and is used to adjust the light spot parameters corresponding to the coupled light signal.
[0040] In this embodiment, the LED component 103 provides a plurality of outgoing light source signals, and the powers of the outgoing light source signals can be superimposed when forming a coupled light signal to obtain a high-power coupled light signal, and the coupled light signal meets a preset band.
[0041] In a possible implementation method, when the light source device 100 further includes a side panel, the dimming module 101 may be disposed on the side panel along the propagation direction of the coupled optical signal to adjust the spot size, shape or uniformity of the coupled optical signal.
[0042] In this embodiment, the dimming module 101 may be composed of a plurality of zoom lenses, wherein the shape, size and uniformity of the light spot corresponding to the coupled light signal may be adjusted by changing the distance or aperture size of each zoom lens. The present invention does not limit the manner in which the dimming module 101 adjusts the shape, size and uniformity of the light spot corresponding to the coupled light signal.
[0043] In a possible implementation, in order to reduce the structural complexity of the light source device 100 , a plurality of outgoing light source signals may be directly provided by the light source module 102 , and coupling of the outgoing light source signals may be completed to obtain a coupled light signal of a preset wavelength band.
[0044] In this embodiment, the LED assembly 103 in the light source module 102 may be composed of a plurality of LED light boards 201, and the LED light boards 201 are used to provide an outgoing light source signal of a preset wavelength. The number of the LED light boards 201 includes at least two.
[0045] In one possible approach, see Figure 2 When the LED assembly 103 includes at least two LED light boards 201 (the number is N, where N is a positive integer), the two LED light boards 201 can be stacked together to ensure that the emission directions of the emission light source signals are the same. In this embodiment, the LED light boards 201 can be arranged in sequence along the optical axis direction, and the emission directions of the emission light source signals corresponding to the LED light boards 201 are parallel and the same.
[0046] Specifically, multiple screw holes can be set around each LED light board 201, except for the central part of the light source, so that multiple LED light boards 201 can be stacked together along the emission direction by screws, and the light emitted by each LED light board 201 is ensured to be in the same direction, that is, the emission directions of each emitted light source signal are ensured to be consistent. Among them, the wavelengths of the emitted light source signals corresponding to each LED light board 201 are all different.
[0047] Further, to obtain the coupled optical signal, please refer to Figure 3 The lens assembly 104 includes a first collimating unit 202, wherein the first collimating unit 202 includes at least one lens with a free-form surface along the emission direction. The lens is used to collimate each emission light source signal to obtain a coupled light signal of a preset wavelength band, and emit the coupled light signal in a preset direction.
[0048] In this embodiment, the LED light board provides multiple outgoing light source signals, and after ensuring that the outgoing directions of the multiple outgoing light source signals are consistent, each outgoing light source signal can be calibrated through a collimation unit in the same direction to obtain a coupled light signal after coupling.
[0049] In an achievable manner, the first collimating unit 202 includes a plurality of free-form surface lenses, so as to collimate the above-mentioned outgoing light source signal through the lenses and form a coupled light signal on the interface where the lenses are located. Figure 4 When the number of lenses is one, the light source module 102 includes an LED assembly 103, a lens barrel 3, and a first lens 2 in sequence along the emission direction. In this embodiment, the LED assembly 103 is connected to the lens barrel 3 through a fixing member 5; the first lens 2 is fixed by a first lens fixing ring 1. For details, please continue to refer to Figure 4The light source module 102 includes an LED component 103, a fixing member 5, a lens barrel fixing ring 4, a lens barrel 3, a first lens 2, and a first lens fixing ring 1 in sequence along the emitting direction. Based on this, this embodiment can form a stable light source device 100 through the above devices.
[0050] In another possible implementation, in order to greatly improve the collimation effect, a plurality of lenses of different sizes can be arranged along the light emitting direction. When the number of lenses is two, the light source module 102 includes an LED assembly 103, a lens barrel 3, a first lens 2 and a second lens in sequence along the emitting direction. In this embodiment, a plurality of lenses of different sizes are arranged along the light emitting direction, which can greatly improve the collimation effect, wherein the size of the first lens 2 is smaller than the size of the second lens. In this embodiment, the small-sized first lens 2 can be used to roughly adjust the outgoing light source signal, and then the large-sized second lens can be used to fine-tune the outgoing light source signal. In a possible implementation, a knob can be set on each lens to adjust the refraction degree corresponding to the lens by means of a knob, so that each divergent outgoing light source signal is focused into a point after passing through the lens, and then diverges into a parallel light beam. At the same time, this embodiment can also use a lens to converge each outgoing light source signal to obtain a coupled light signal.
[0051] Similarly, in this embodiment, the LED assembly 103 is connected to the lens barrel 3 through the fixing member 5; the first lens 2 and the second lens are fixed by the first lens fixing ring 1 and the second lens fixing ring respectively. Specifically, the light source module 102 includes the LED assembly 103, the fixing member 5, the lens barrel fixing ring 4, the lens barrel 3, the first lens 2, the first lens fixing ring 1, the second lens and the second lens fixing ring in sequence along the emission direction. In this embodiment, a stable light source device 100 is formed by the above components.
[0052] In another embodiment, in order to reduce the size of the light source device 100 and increase the heat dissipation capacity, a plurality of outgoing light source signals can be directly provided through the light source module 102, and then a coupling unit is set in the lens assembly 104 to complete the coupling of each outgoing light source signal to obtain a coupled light signal of a preset band.
[0053] Please refer to Figure 5 When the LED assembly 103 includes a plurality of monochromatic light emitting elements 301 and the lens assembly 104 includes a coupling unit 302, each monochromatic light emitting element 301 is used to provide an outgoing light source signal of a different preset wavelength; the coupling unit 302 is used to couple each outgoing light source signal to obtain a coupled light signal of a preset wavelength band, and emit the coupled light signal in a preset direction. In this embodiment, the monochromatic light emitting element 301 may include an LED light board 201.
[0054] In this embodiment, each monochromatic light emitting element is used to provide an outgoing light source signal of a specific wavelength, and the coupling unit is used to receive each outgoing light source signal and filter out the outgoing light source signal within a preset wavelength band to construct a coupled light signal, obtain a coupled light signal of a preset wavelength band, and emit the coupled light signal in a preset direction. It should be noted that the emitting direction of each outgoing light source signal is not limited in this embodiment, and in this embodiment, each outgoing light source signal can be coupled through the coupling unit to obtain a coupled light signal emitted along a preset direction.
[0055] In a possible implementation, in order to ensure the dispersion of each outgoing light source signal, so that it can be received by the coupling unit 302, please refer to Figure 6 In this embodiment, the lens assembly 104 includes a plurality of second collimating units 303, each second collimating unit 303 corresponds to a monochromatic light emitting element 301, and the second collimating unit 303 is arranged in the emitting direction of each emitting light source signal to collimate each emitting light source signal.
[0056] In this embodiment, the structure of the second collimating unit 303 can refer to the first collimating unit 202 in the above embodiment, that is, please continue to refer to Figure 4 The second collimating unit 303 may include a plurality of free-form surface lenses to collimate the above-mentioned outgoing light source signal through the lenses. The difference between this embodiment and the previous embodiment is that this embodiment includes a plurality of second collimating units 303, and each second collimating unit 303 corresponds to a monochromatic light emitting element 301 one by one to collimate the outgoing light source signal provided by each monochromatic light emitting element 301. In addition, in this embodiment, the second collimating unit 303 does not couple each outgoing light source signal.
[0057] This embodiment also includes a coupling unit 302, which is used to filter the wavelength of the outgoing light source signal to obtain a coupled light signal of a preset wavelength band. Figure 7 , when the coupling unit 302 includes multiple dichroic mirrors; the dichroic mirrors are arranged in the emission direction of the outgoing light source signal to select the outgoing light source signal of the required wavelength, construct a coupled light signal of a preset band, and emit the coupled light signal in a preset direction.
[0058] In a possible implementation, to ensure the coupling effect of the dichroic mirrors, the direction angle θ between the surface normal of each dichroic mirror and the straight line where the emission direction is located satisfies: θ=45°. When the number of monochromatic light emitting elements 301 is N, the number of dichroic mirrors is N+1.
[0059] In this embodiment, please continue to refer to Figure 7As an optical element, a dichroic mirror can be used to separate and combine different wavelengths. For example, it can reflect long wavelengths through short wavelengths, or reflect short wavelengths through long wavelengths. For example, when a light signal of 500 nanometers to 700 nanometers is required, a dichroic mirror with a 500-nanometer characteristic and a dichroic mirror with a 700-nanometer characteristic can be selected. At this time, the dichroic mirror is equivalent to a selective switch; when the wavelength of the outgoing light source signal exceeds 500 nanometers, it can be reflected by the dichroic mirror with a 500-nanometer characteristic; when the wavelength of the outgoing light source signal is less than or equal to 500 nanometers, it can be transmitted by the dichroic mirror with a 500-nanometer characteristic.
[0060] Similarly, when the wavelength of the outgoing light source signal is less than or equal to 700 nanometers, it can be transmitted by the dichroic mirror with 700 nanometer characteristics; when the wavelength of the outgoing light source signal is greater than 700 nanometers, it can be reflected by the dichroic mirror with 700 nanometer characteristics.
[0061] In this embodiment, the corresponding dichroic mirror can be selected based on the preset band requirement, and the position of the dichroic mirror can be adjusted according to the preset emission direction of the coupled optical signal. In this embodiment, the position of the dichroic mirror is not limited, and it is only necessary to make the direction angle between the surface normal of each dichroic mirror and the straight line where the emission direction is located be 45°.
[0062] In this embodiment, multiple single-color light emitting elements can be provided or multiple LED light boards 201 can be stacked along the emitting direction, and each single-color light emitting element and each LED light board 201 can use high-power LED devices to increase the power of the LED assembly 103, and thus can be suitable for LED devices with high-power output performance. In order to improve the heat dissipation performance, the LED assembly 103 also includes multiple heat sinks 105, and the heat sinks 105 are provided on the back panel of the single-color light emitting element 301 or the LED light board 201, wherein screw holes can be provided on the back panel of the single-color light emitting element 301 or the LED light board 201, so that the heat sinks 105 can be fixed to the back panel of the single-color light emitting element 301 or the back panel of the LED light board 201 by screws. In order to provide heat dissipation performance and reduce the device size of the light source device 100, please refer to Figure 8 , an integrated heat sink can be selected, and the heat sink 105 can be directly set on the back plate of the single-color light emitting element 301 or the LED light board 201.
[0063] To further improve the heat dissipation performance, please continue to refer to Figure 8In this embodiment, the light source device 100 further includes an outer cover 6, a side plate 7 and a heat dissipation fan 8. The side plate 7 is also provided with an air outlet and an air inlet; the heat dissipation fan 8 is provided at the air inlet; the heat dissipation elements 105 are arranged in sequence, and form a heat dissipation duct with the air outlet, the air inlet, the outer cover 6 and the side plate 7. In a possible implementation, in order to reduce the structure of the light source device 100, the heat dissipation duct can be set as an L-shaped heat dissipation cavity, that is, the heat dissipation elements 105 are arranged in sequence to form an L-shape, and then form an L-shaped cavity with the outer cover 6, the side plate 7 and the bottom plate 9, and then the heat dissipation fan 8 is used to form an airflow in the heat dissipation cavity to reduce the temperature of the light source device 100, such as the ambient temperature or the problem of the device itself.
[0064] In this embodiment, the heat dissipation fan 8 can be an exhaust type heat dissipation fan 8 or a blow type heat dissipation fan 8 .
[0065] Second, please refer to Fig. 9 The utility model further provides a light source system 400, which includes a power supply device 401 and the light source device 100 of any one of the first aspects above; the power supply device 401 is electrically connected to the light source device 100 to supply power to the light source device 100.
