[0038] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0039] In order to increase the power, LED lamps in the prior art usually include multiple LED lamp beads. In order to achieve better lighting effects, each LED lamp bead corresponds to a lens, and the concave and convex shape of the lens is used to change the propagation direction of the light, so that the light emitted by each LED lamp bead is focused into a more concentrated light beam.

[0040] For zoom LED lamps, it is often necessary to adjust the focus of the light by moving and adjusting the distance between the LED lamp beads and the reflective cup, so a displacement adjustment mechanism for adjusting the distance between the LED lamp beads and the reflective cup is set inside the LED lamp. The additional setting of the displacement adjustment mechanism makes the volume of the LED lamp too large, which cannot meet the user's demand for a small volume of LED lamps.

[0041] In order to overcome the above problems, the present invention provides a mobile lighting source and a control method thereof, wherein the mobile lighting source comprises a light source and a lens; the lens is coaxially arranged with the light source; the light source comprises a plurality of light zones, each of which is coaxially arranged, and each of which contains a single or a plurality of light-emitting units; the lens comprises a plurality of light-receiving parts, each of which is coaxially arranged, and the light-receiving parts project the light received from the light source to form a desired light spot. A zoom lens is provided to cooperate with refraction to achieve a zoom effect, thereby overcoming the problem that the light source structure itself is too large due to the need to use a complex optical path structure to achieve zoom of the light source, and improving the overall compactness of the mobile lighting source.

[0042] A mobile lighting source and a control method thereof provided by the present application are described in more detail below in conjunction with the accompanying drawings.

[0043] like Figure 1As shown, the present application provides a mobile lighting light source, which includes: a light source 110 and a lens; the lens is coaxially arranged with the light source; the light source includes a plurality of light zones, each of the light zones is coaxially arranged, and each of the light zones contains a single or a plurality of light-emitting units; the lens includes a plurality of light-receiving members, each of the light-receiving members is coaxially arranged, the light-receiving member is either an internal light-receiving member or an external light-receiving member, the light zone is either an internal light zone or an external light zone, the light-receiving surface of the internal light-receiving member is arranged toward the light-emitting surface of the internal light zone, the light-receiving surface of the external light-receiving member is arranged toward the light-emitting surface of the external light zone, and the light-receiving member projects the light received from the light source to form a desired light spot.

[0044] Specifically, the lens is arranged in front of the light source, and the lens and the light source are arranged coaxially to realize that the light emitted by the light source forms high-quality light through the lens. The lens and the light source are arranged coaxially so that the main optical axis of the lens coincides with the optical axis of the light source.

[0045] Furthermore, the light source includes a plurality of light zones, each of which is also coaxially arranged. Each light zone contains a single or multiple light-emitting units, and the light-emitting units may be LED lamps, and each LED lamp in the light zone forms an LED array.

[0046] Furthermore, the lens in the mobile lighting source of this embodiment includes a plurality of light receiving elements, each of which receives light emitted by the light source and refracts the received light emitted by the light source to form a desired light spot. Specifically, each of the light receiving elements is coaxially arranged, that is, the central axes of each of the light receiving elements are aligned with each other to form a continuous straight line, so that the light of the light source is not deflected or scattered during transmission overshoot, thereby improving the optical performance of the mobile lighting source.

[0047] Combination Figure 1 and Figure 2 As shown, the light receiving member is either an internal light receiving member 130 or an external light receiving member 120. The internal light receiving member is arranged inside the external light receiving member, and the internal light receiving member processes the light received from the light source and then emits it, or the external light receiving member processes the light received from the light source and then emits it, so as to form a focused light spot. The internal light receiving member and the external light receiving member are in a split structure, and a fixing pile is arranged on one side of the external light receiving member, and the internal light receiving member is fixed on the fixing pile.

[0048] It is conceivable that, in another embodiment, the lens is formed by integrally molding a plurality of the light-receiving parts. Not only can the production efficiency be improved and the processing steps be significantly reduced in the process of manufacturing the lens, but also the lens can be produced quickly and efficiently. Since the inner light-receiving part and the outer light-receiving part can be directly processed into a whole by injection molding or turning, it not only reduces the error of component assembly, ensures the accuracy and repeatability of the lens, but also improves the optical imaging quality.

[0049] The light zone is either an inner light zone or an outer light zone, the light receiving surface of the inner light receiving member is arranged toward the light emitting surface of the inner light zone, and the light receiving surface of the outer light receiving member is arranged toward the light emitting surface of the outer light zone. Further, the light emitting surfaces of the inner light zone and the outer light zone are not in the same plane, the light emitting surface of the inner light zone is arranged higher than the light emitting surface of the outer light zone, or the light emitting surface of the inner light zone is arranged lower than the light emitting surface of the outer light zone.

[0050] In one embodiment, the light source is a self-luminous body, and the irradiation wavelengths of the light-emitting units of the light source can be the same wavelength or different wavelengths.

[0051] Specifically, the inner light area includes: a single or multiple LED arrays; the outer light area includes multiple CSP packaged LED arrays, or COB packaged LED arrays, or a single or multiple LED arrays; or, the inner light area includes: multiple CSP packaged LED arrays; the outer light area includes multiple CSP packaged LED arrays, or COB packaged LED arrays, or a single or multiple LED arrays.

[0052] In one embodiment, each light-emitting unit in the light zone is a plurality of optical fibers, a light-guiding column, a reflective prism, or a plurality of externally connected non-self-luminous sources, and the irradiation wavelengths between each light-emitting unit of the light source can be the same wavelength or different wavelengths. Preferably, in order to achieve a better effect of focusing the light emitted by the light source, the light-receiving element disposed on the outermost side of the lens is a reflective cup lens.

[0053] Combination Figure 1 and Figure 2As shown, the light receiving member includes: an inner light receiving member 130 and an outer light receiving member 120, wherein the inner light receiving member 130 is fixed inside the outer light receiving member 120; the light-collecting surface of the inner light receiving member 130 is in contact with the light-emitting surface of the light source. The inner light receiving member 130 and the outer light receiving member 120 have the same center point, which is located on the optical axis of the light source. The outer light receiving member wraps the inner light receiving member inside. Both the inner light receiving member and the outer light receiving member are used to collect the light emitted by the light source, refract the light so that the light is focused on the optical axis of the mobile lighting light source, and guide the light to the outer light receiving member, which focuses the received light on the optical axis of the mobile lighting light source, thereby forming a coaxial light source and realizing the focal length adjustment of the light source. The inner light receiving member usually needs to meet the characteristics of high light transmittance and high temperature resistance to ensure the stability of the optical performance. The outer light receiving member is usually composed of multiple layers of materials, such as alternating layers of silver-aluminum oxide. The radius of the outer light receiving element is greater than the radius of the inner lens to provide an imaging space.

[0054] Combination Figure 2 As shown, in one embodiment, the inner light receiving member and the outer light receiving member can be configured as a detachable structure. The inner light receiving member 130 and the outer light receiving member 120 constitute a cup body structure. A fixing pile is provided on the inner side of the cup bottom of the outer light receiving member 120, and the inner light receiving member is buckled and fixed on the fixing pile, and is located in front of the light source 110. The inner light receiving member 130 and the outer light receiving member 120 are in a double-layer structure. The outer light receiving member is made of PC material, and the inner light receiving member is made of silicone material. Since the inner light receiving member uses silicone material, the heat resistance temperature of the inner light receiving member can be improved, thereby preventing the inner light receiving member and the light source from being damaged due to excessive temperature during irradiation.

[0055] Furthermore, the inner light receiving part includes a lens barrel and a lens piece, and the lens piece is made of glass or other transparent materials and has different shapes and curvatures to achieve refraction and focusing of the received light. The lens piece can be a plano-convex lens, a biconvex lens, a concave lens, etc. In order to achieve a better light control effect, the inner light receiving part may also include a filter and an aperture to adjust and control the light. The outer light receiving part may be composed of a plurality of lenses, which can converge the received divergent light to form a collimated (parallel) light beam. In a specific implementation, the imaging range can also be continuously adjusted by changing the focal length or position of the outer light receiving part to meet different lighting requirements, and the outer light receiving part can also optimize the transmission path of the light and improve the lighting quality.

[0056] Furthermore, combined with Figure 3 As shown, the light source includes: multiple light zones, which can also be divided into an inner light zone 304 and an outer light zone 302; the inner light zone 304 is located inside the outer light zone, and the inner light zone 304 and the outer light zone 302 both include multiple light-emitting units, each of which is a coaxial light source.

[0057] In detail, the focusing surface of the inner light receiving element includes a focusing area 303 and a diffusion area 301. When the focusing surface of the inner light receiving element is set close to the light emitting surface of the light source, the focusing area 303 is close to the inner light area 304, and the diffusion area 301 is close to the outer light area 302. When the focusing area 303 or the diffusion area 301 is lit, the inner lens refracts light spots with different halos after receiving the light, thereby realizing the final coaxial focal length adjustment function. The focusing surface of the inner lens is designed in a curved surface, which is convenient for receiving the light emitted by the light source and focusing the received light. In this embodiment, the focusing surface is close to the light emitting surface of the light source to maximize the utilization rate and focusing effect of the light. Since the light is captured by the lens after leaving the LED, the scattering and loss of the light are reduced.

[0058] In one embodiment, the light source is configured as an inner light area and an outer light area. Figure 3 As shown, the light source is divided into an inner light area 304 and an outer light area 302, and the area on the inner light receiving element is correspondingly divided into a diffusion area 301 and a focusing area 303. Since the inner light receiving element is arranged close to the light-emitting surface of the light source, the inner light area of ​​the light source is close to the focusing area of ​​the inner lens, and the outer light area of ​​the light source is close to the diffusion area of ​​the inner lens. When the light-emitting unit in the inner light area is lit, the current state is regarded as the light source being in the focusing mode, and when the light-emitting unit in the outer light area is lit, the current state is regarded as the light source being in the floodlight mode.

[0059] When the light source is in the spotlight mode, the inner light area lights up, and the main light emitted is directly emitted through the spotlight area. The divergent light caused by light leakage can also pass through the diffusion area and then be refracted by the external light receiving element and finally emitted. Figure 4 shown.

[0060] When the light source is in floodlight mode, the light emitting unit in the outer light area lights up, and the main light emitted is refracted in the diffusion area and directly emitted after light guidance. The light refraction path is as follows: Figure 5 shown.

[0061] When the light source is in a composite mode of the spotlight mode and the floodlight mode, the inner light area and the outer light area are lit at the same time, and the light refraction path is as follows: Figure 6 As shown, the spotlight mode and the floodlight mode are superimposed.

[0062] It can be imagined that when the inner light zone 304 and the outer light zone 302 are lit at the same time, the light source 110 can adjust the focusing effect of the illuminated light spot by adjusting the brightness of the light emitted by the inner light zone 304 and the outer light zone 302. Specifically, when the light source 110 adjusts the brightness of the light emitted by the inner light zone 304 to be greater than the brightness of the light emitted by the outer light zone 302, the light spot emitted by the light source 110 tends to be in a gathered state; conversely, when the light source 110 adjusts the brightness of the light emitted by the inner light zone 304 to be less than the brightness of the light emitted by the outer light zone 302, the light spot emitted by the light source 110 tends to be in a flooded state.

[0063] Specifically, Figure 7 As shown, the inner light zone and the outer light zone can be arranged so that both of them are annular structures; the inner light zone is located inside the outer light zone, that is, the outer light zone is located outside the inner light zone. The light source can control the light emitting units in the inner light zone to emit light or the light emitting units in the outer light zone to emit light, so that the light emitted in the inner light zone is emitted through the focusing area of ​​the inner light receiving member, or the light emitted by the light emitting units in the outer light zone is directly emitted after being refracted and transmitted through the diffusion area of ​​the inner light receiving member.

[0064] Furthermore, the inner light zone or the outer light zone includes multiple light-emitting areas, each of which contains multiple light-emitting units; the light-emitting areas in the inner light zone and the outer light zone are arranged regularly, and the light-emitting units in the inner light zone are surrounded by the light-emitting units in the outer light zone.

[0065] The plurality of light emitting units in the inner light zone and the outer light zone are in a ring structure, a square structure or a fan-shaped structure. Figure 7 As shown, the light source is circular in shape as a whole, wherein the inner light zone 304 is designed as a circle, and the outer light zone 302 is designed as a ring, and the inner light zone 304 is inside the outer light zone 302. The light source is rectangular in structure as a whole, wherein the inner light zone 304 is located at the center, and the outer light zone 302 is divided into 8 areas, which are respectively located above, below, left, right, upper right, lower right, upper left and lower left of the inner light zone 304. In addition, the overall shape of the light source can also be set to a regular hexagon, wherein the inner light zone 304 is located at the center of the regular hexagon, and the outer light zone 302 is divided into six areas, which are evenly arranged in a ring around the inner light zone at fixed intervals.

[0066] In one implementation, the inner light zone and the outer light zone are self-luminous bodies, and the inner light zone includes: a single or multiple LED arrays, or multiple CSP packaged LED arrays; the outer light zone includes multiple CSP packaged LED arrays, or COB packaged LED arrays, or a single or multiple LED arrays. That is, the inner light zone includes: a single or multiple LEDs, and the outer light zone includes multiple CSP light-emitting chip arrays. Or the inner light zone includes: multiple CSP packaged LED arrays, and the outer light zone includes multiple CSP packaged LED arrays or COB packaged LED arrays.

[0067] It is conceivable that the light-emitting unit in the outer light area can be composed of a number of regularly arranged LED chips or directly composed of a COB light source.

[0068] The emitted light of the inner light zone and the outer light zone may be light sources of the same or different wavelengths, that is, when the inner light zone or the outer light zone is a self-luminous light source composed of a plurality of CSP light-emitting chips or a plurality of LED light-emitting chips, the CSP light-emitting chips or LED light-emitting chips arranged in adjacent or different light-emitting areas (several light-emitting areas divided by the inner light zone and the outer light zone, and the shape of the light-emitting areas is not limited, such as a fan or a square, etc.) may be light sources of the same or different wavelengths.

[0069] In another implementation, the light-emitting units in the inner light zone or each light-emitting unit in the outer light zone can be multiple optical fibers or multiple externally connected non-self-luminous sources, and the wavelength of each light-emitting unit in the inner light zone is the same as or different from the wavelength of each light-emitting unit in the outer light zone.

[0070] When the inner light zone or the outer light zone is a non-self-luminous light source composed of several optical fibers or several external light guides, the optical fibers or external light guides corresponding to adjacent or different light-emitting areas (several light-emitting areas divided by the inner light zone and the outer light zone, and the shapes of the light-emitting areas are not limited, such as fans or squares, etc.) can be connected to external light sources and transmit light sources of the same or different wavelengths.

[0071] Specifically, the focusing surface of the inner light receiving element includes a focusing area and a diffusion area, the focusing area is close to the inner light area, and the diffusion area is close to the outer light area; the focusing area or the diffusion area refracts the received light and outputs light spots with different halos.

[0072] In addition, this embodiment provides a mobile lighting source control method based on the premise of providing the above mobile lighting source. Figure 8 As shown, including:

[0073] Step S1: A light source obtains an input light source control signal group, where the light source control signal group is used to adjust an illumination parameter of the light source.

[0074] The light source control signal group contains multiple different control signals, which can be used to adjust various illumination parameters of the light source, such as brightness, color temperature, color, etc. The control signals input through the light source control signal group can realize the diverse needs of the light source in different application scenarios.

[0075] When the light source receives a series of control signals input by the light source control signal group, each light-emitting unit in the light source is controlled according to the control signals contained in the light source control signal group to adjust the illumination parameters of each light-emitting unit.

[0076] Step S2: the light source adjusts light parameters of the emitted light according to the light source control signal group, and irradiates the lens arranged in front of the light source after the adjustment.

[0077] When each light-emitting unit in the light source makes corresponding light parameter adjustments according to the control signal contained in the light source control signal group, the light output by the light-emitting unit after adjustment is input to the lens surface in front of the light source.

[0078] Furthermore, the light source control signal group includes a power control signal, a wavelength control signal and a range control signal, combined with Fig. 9 As shown, the step S2 specifically includes:

[0079] Step S2a: the light source controls the brightness of each internal light zone according to the power control signal.

[0080] The light source controls the luminous power of each luminous unit according to the received power control signal, thereby controlling the lighting brightness of each internal light zone.

[0081] Step 2b: the light source controls the lighting wavelength of each internal light zone according to the wavelength control signal.

[0082] The light source controls the wavelength of light emitted by each light-emitting unit according to the received wavelength control signal, thereby controlling the lighting wavelength of each internal light zone.

[0083] Step S2c: the light source controls the lighting range of each internal light zone according to the range control signal.

[0084] The light source controls the irradiation range of the light projected by each light-emitting unit according to the received range control signal, thereby controlling the lighting range of each internal light zone.

[0085] The light source control signal group controls the brightness, wavelength and range of each internal light zone by respectively controlling the power of the light source, the wavelength of the emitted light and the irradiation range of the emitted light.

[0086] Step S3: The lens projects the light emitted by the light source to form a desired light spot.

[0087] After the lens receives the light from the light source, it projects the received light to form the desired light spot. Figures 4 to 6 shown.

[0088] Since the lens includes multiple light-receiving parts, the light-receiving parts include an inner light-receiving part and an outer light-receiving part, both the inner light-receiving part and the outer light-receiving part are used to collect the light emitted by the light source and refract the light so that the refracted light is focused on the optical axis of the light source, thereby achieving the focusing of the light, keeping the structure of the light source compact and avoiding the light source structure being too large.

[0089] The present embodiment provides a mobile lighting light source and a control method thereof. A zoom lens is provided to refract the light emitted by the light source so as to keep the light emitted by the light source coaxial and in the same plane. There is no need to use a complex physical displacement structure to drive the light source to move to achieve the technical effect of zooming, making the optical structure more compact. This solves the problem in the prior art that the zoom light source needs to be driven by a physical displacement structure, resulting in an overly large structure of the light source itself. This ensures the zoom effect while reducing the volume of the light source structure.
