[0002] The flash lamp is one of the important tools to improve the quality of taking pictures, and it can usually be installed on the top of a camera through a camera hot shoe. The common top-mounted flash lamp generally uses a xenon lamp tube as the light source of the flash lamp. The spectral distribution of the xenon lamp is close to that of sunlight. If a photographer wants to obtain different color temperature effects, a color temperature conversion filter plate is usually needed, but such an operation is very inconvenient for users. With the development of technology, there has also emerged a flash lamp with a constant-brightness LED lamp. The softer light of the LED lamp can show more abundant details of the photographed object. However, in scenes where high-brightness shooting is required or the ambient light is too low, the brightness of the LED lamp is insufficient, so its scope of use is limited.

[0003] Therefore, there are still many places that can be improved in the existing flash lamps to meet the more abundant shooting needs and personalized creation pursuits of photographers. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The typical embodiments embodying the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various variations in different embodiments, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

[0025] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indication of the direction or positional relationship (such as up, down, left, right, front and back, etc.) is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. When these elements are in the positions shown in the drawings, these descriptions are appropriate. If the description of the positions of these elements changes, then the indication of these directions also changes accordingly.

[0026] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0027] The present application provides a flash lamp, which can be mounted on the top of a camera through a camera hot shoe, and the flash lamp is electrically connected to the camera, so that when using the camera for shooting, the flash lamp can provide illumination for the object or scene to be photographed under low light conditions. For the best color rendering, the color of the flash lamp should match the tone of the object to be photographed and / or the entire photographic scene, thereby improving the quality of the captured image.

[0028] Refer to Figure 1 and Figure 2 , the flash lamp includes a housing 1, a circuit board 5, an LED lamp 2 and a xenon lamp 3. The housing 1 is provided with a receiving cavity 11 and a light outlet, and the light outlet communicates the receiving cavity 11 with the outside of the housing 1. The circuit board 5, the LED lamp 2 and the xenon lamp 3 are all installed in the receiving cavity 11. Moreover, the LED lamp 2 and the xenon lamp 3 are both electrically connected to the circuit board 5, so that the circuit board 5 can control the operation of the LED lamp 2 and the xenon lamp 3. The light generated by the LED lamp 2 and the light generated by the xenon lamp 3 are both emitted from the light outlet.

[0029] Among them, LED lamp 2 can provide soft lighting for the photographed object, and xenon lamp 3 can provide high-brightness lighting for the photographed object. Therefore, by setting up LED lamp 2 and xenon lamp 3, the flash can provide both soft lighting and high-brightness lighting for the photographed object. It is also possible to use LED lamp 2 and xenon lamp 3 simultaneously for fill light, increasing the chromaticity of the fill light, thereby making the flash suitable for shooting scenes with different brightness. In other words, the flash of this application can meet the needs of different flash effects in different shooting scenes, fully meeting the needs of more personalized creations. Moreover, during use, you can turn on the corresponding lamp as needed, making it convenient to use.

[0030] The xenon lamp 3 is arranged in the optical path of the LED lamp 2, and the light emitting area of the LED lamp 2 coincides with the light emitting area of the xenon lamp 3, so that the light spot position generated by the LED lamp 2 in the flash is the same as the light spot position generated by the xenon lamp 3, thereby making the light output of the flash more uniform.

[0031] For details, see Figure 2 and Figure 3 The circuit board 5 is disposed within the accommodating cavity 11 and is located on the side of the LED lamp 2 and the xenon lamp 3 facing away from the light outlet of the accommodating cavity 11. This ensures that the circuit board 5 does not block the light emitted by the LED lamp 2 and the xenon lamp 3 toward the light outlet. An LED flash circuit 51 and a xenon flash circuit 52 are disposed on the circuit board 5. The LED lamp 2 is electrically connected to the LED flash circuit 51 and its operation is controlled by the LED flash circuit 51. The xenon lamp 3 is electrically connected to the xenon flash circuit 52 and its operation is controlled by the xenon flash circuit 52. The LED flash circuit 51 and the xenon flash circuit 52 are both disposed on the circuit board 5 of the flash, allowing the flash to be compatible with various existing camera models without requiring the LED flash circuit 51 and the xenon flash circuit 52 to be disposed on the camera's control panel.

[0032] The LED flash circuit 51 includes a capacitor energy storage circuit 501 and a first flash control circuit 502. A first end of the capacitor energy storage circuit 501 is electrically connected to the LED lamp 2, a second end of the capacitor energy storage circuit 501 is grounded, and the first end of the capacitor energy storage circuit 501 is also connected to a power supply voltage VIN. The capacitor energy storage circuit 501 can store a certain amount of electricity. When a flash is required, the stored electricity can be output to the LED lamp 2, enabling the LED lamp 2 to emit a corresponding flash. The first flash control circuit 502 is electrically connected to the LED lamp 2 and can control the flash energy of the LED lamp 2. In other words, the capacitor energy storage circuit 501 and the first flash control circuit 502 can be used to cause the LED lamp 2 to emit flashes with different luminous parameters (such as different color temperatures or colors), or combinations thereof.

[0033] The xenon flash circuit 52 mainly activates xenon using high-voltage current to form a beam of arc light, providing high color temperature and highly concentrated illumination. This technology breaks the traditional tungsten filament lighting principle. By filling high-pressure inert gas (i.e., xenon) in the quartz lamp tube 31, it replaces the traditional filament. When the xenon is stimulated by a high-voltage current of up to 23,000 volts through the ballast, a perfect white arc is formed between the two electrodes, and the light emitted is close to very perfect sunlight. This technology not only increases the color temperature but also greatly reduces energy consumption.

[0034] The triggering method of the xenon flash circuit 52 is to use a high-voltage capacitor to store sufficient energy and then release the energy to the lamp tube 31. This energy will stimulate the xenon in the lamp tube 31 to generate light. The lighting principle of the xenon lamp 3 is to use positive and negative electricity to stimulate the chemical reaction of argon and rare metals to emit light. Therefore, there is a small glass ball in the lamp tube 31 filled with argon and a little rare metal. As long as an electric current is used to stimulate them to carry out a chemical reaction, the two will emit light with a color temperature of up to 4000K - 12000K. The xenon flash circuit 52 has a flash illumination function with a wide spectrum similar to sunlight.

[0035] The xenon flash circuit 52 includes a capacitive energy storage circuit 501 and a second flash control circuit 503. The first end of the capacitive energy storage circuit 501 is electrically connected to the xenon lamp 3, and the second flash control circuit 503 is electrically connected to the xenon lamp 3. The second flash control circuit 503 is used to control the flash energy of the xenon lamp 3 tube.

[0036] In one embodiment, the LED flash circuit 51 and the xenon flash circuit 52 can share a capacitive energy storage circuit 501, which can save circuit components and the layout space of circuit components, and can save costs. In other embodiments, the LED flash circuit 51 and the xenon flash circuit 52 may not share the capacitive energy storage circuit 501, that is, the LED flash circuit 51 and the xenon flash circuit 52 can each contain a corresponding capacitive energy storage circuit 501 respectively.

[0037] In one embodiment, at least one of the LED flash circuit 51 and the xenon flash circuit 52 is provided on the circuit board 5. For example: the xenon flash circuit 52 is provided on the circuit board 5, and the LED flash circuit 51 is provided on the lamp board 21 of the LED lamp 2. Another example: the LED flash circuit 51 is provided on the circuit board 5, and the xenon flash circuit 52 is provided on the control board in the camera or the control board in the camera body 8.

[0038] In one embodiment, the flash may not be provided with a circuit board 5, and both the LED flash circuit 51 and the xenon flash circuit 52 are provided on the control board inside the camera or the control board inside the body 8. Moreover, the LED lamp 2 and the xenon lamp 3 are electrically connected to the control board inside the camera or the control board inside the body 8 through wires, so as to realize the electrical connection between the LED lamp 2 and the LED flash circuit 51 and the electrical connection between the xenon lamp 3 and the xenon flash circuit 52.

[0039] In Figure 2 In the illustrated embodiment, the circuit board 5 is configured as one piece, and the LED flash circuit 51 and the xenon flash circuit 52 are provided on the circuit board 5, so that the flash can be adapted to existing different models of cameras, and the structure of the flash is also made more concise. In other embodiments, the circuit board 5 is configured with multiple pieces, and the LED flash circuit 51 and the xenon flash circuit 52 can be respectively provided on different circuit boards 5. Among them, when the circuit board 5 is configured with multiple pieces, the multiple circuit boards can be arranged along the axial direction of the housing 1 or along the radial direction of the housing 1.

[0040] Referring to Figure 4 , the LED lamp 2 includes a lamp board 21 and lamp beads 22. The lamp board 21 is electrically connected to the circuit board 5, the lamp beads 22 are soldered on the lamp board 21, and the lamp beads 22 are electrically connected to the circuit board 5 through the lamp board 21. In Figure 4 In the illustrated embodiment, the lamp board 21 is attached to the side of the circuit board 5 facing the light outlet, and the lamp board 21 and the circuit board 5 can be adhesively connected, soldered or screwed, so that the lamp board 21 and the circuit board 5 are fixed as a whole, and the overall structure formed by the two is more compact. In other embodiments, the lamp beads 22 can also be directly integrated on the circuit board 5; or the lamp board 21 and the circuit board 5 are arranged at intervals.

[0041] Referring to Figure 5 , a plurality of lamp beads 22 are provided. When the plurality of lamp beads 22 work simultaneously, the illumination brightness of the LED lamp 2 can be increased. When the plurality of lamp beads 22 do not work simultaneously, by controlling the number of working lamp beads, the adjustment range of the illumination brightness and color temperature of the LED lamp 2 can be increased. Among them, the plurality of lamp beads 22 are arranged at intervals on the lamp board 21, so that the plurality of lamp beads 22 do not affect each other's light emission.

[0042] In one embodiment, the lamp beads 22 include one or more of a monochromatic LED lamp bead, a two-color temperature LED lamp bead, and a color LED lamp bead. When the lamp beads 22 are one of the two-color temperature LED lamp bead and the color LED lamp bead, or when the lamp beads 22 are multiple of the monochromatic LED lamp bead, the two-color temperature LED lamp bead, and the color LED lamp bead, the color temperature of the LED lamp 2 can be increased.

[0043] In other embodiments, the lamp beads 22 can also be set to one.

[0044] Refer to Figure 2 and Figures 4 to 5 , the xenon lamp 3 includes a lamp tube 31 and xenon lamp electrodes 32. The lamp tube 31 is located on the light-emitting port side of the circuit board 5 close to the accommodating cavity 11. The length direction of the xenon lamp electrodes 32 is arranged along the axial direction of the housing 1 and is located outside the lamp board 21. The xenon lamp electrodes 32 are electrically connected to the lamp tube 31 and the circuit board 5, so that the xenon lamp electrodes 32 not only support the lamp tube 31, eliminating the need for an additional bracket for installing the xenon lamp 3, making the structure simpler and more compact, but also enabling the lamp tube 31 to be powered on. When the xenon lamp electrodes 32 are powered on, the voltage on the xenon lamp electrodes 32 causes xenon electrons to ionize, generating a light source between the two electrodes, that is, the xenon gas in the lamp tube 31 discharges, realizing the illumination of the xenon lamp 3. Among them, the axial direction of the housing 1 refers to the extending direction of the center line of the accommodating cavity 11, and the radial direction of the housing 1 refers to the direction perpendicular to the center line of the accommodating cavity 11.

[0045] The lamp tube 31 is the main light-emitting part of the xenon lamp 3. When the xenon lamp 3 works, a large amount of heat is generated at the lamp tube 31. In this application, the lamp tube 31 and the circuit board 5 are arranged at an axial interval along the housing 1 and have a certain distance, so as to reduce the influence of temperature rise on the circuit board 5.

[0046] The lamp tube 31 and the LED lamp 2 are arranged at an axial interval along the housing 1 and have a certain distance, so as to reduce the influence of temperature rise on the LED lamp 2.

[0047] The lamp tube 31 is arranged on the side of the lamp beads 22 close to the light-emitting port, and the xenon lamp electrodes 32 are arranged on the circumferential side of the lamp board 21 of the LED lamp 2, so that the lamp tube 31 of the xenon lamp 3 can be located on the light path of the LED lamp 2, and the LED lamp 2 does not affect the electrical connection between the xenon lamp 3 and the circuit board 5.

[0048] Among them, the lamp tube 31 is a light-transmitting structure, that is, the light of the lamp beads 22 can pass through the lamp tube 31, so as to reduce the influence of the lamp tube 31 on the light path of the lamp beads 22 and realize the coincidence of the light-emitting area of the xenon lamp 3 and the light-emitting area of the LED lamp 2. The lamp board 21 of the LED lamp 2 is an opaque structure. When the xenon lamp 3 is arranged between the LED lamp 2 and the circuit board 5, the LED lamp 2 will block the light of the xenon lamp 3, thereby affecting the light-emitting effect of the flash lamp.

[0049] In one embodiment, the lamp tube 31 is arc-shaped, and the plane where the arc-shaped lamp tube 31 is located is on the cross-section of the housing 1, that is, the plane where the arc-shaped lamp tube 31 is located is perpendicular to the xenon lamp electrodes 32, so as to increase the light-emitting area of the lamp tube 31 and shorten the length of the lamp tube 31 in the axial direction of the housing 1, thereby shortening the length of the flash lamp.

[0050] The projection of the lamp bead 22 in the axial direction of the housing 1 is located within the projection range of the lamp tube 31 in the axial direction of the housing 1, and does not coincide with the projection range of the lamp tube 31 in the axial direction of the housing 1. That is, the projection of the lamp tube 31 in the axial direction of the housing 1 forms an annular shape or an arc greater than a semi-circle, and the projection of the lamp bead 22 in the axial direction of the housing 1 is located inside the annular shape or the arc. With such a setting, part of the light of the lamp bead 22 can be emitted along the center of the lamp tube 31, ensuring the illumination intensity of the LED lamp 2. Moreover, the light-emitting position of the LED lamp 2 is concentrated, avoiding uneven illumination. The light of the LED lamp 2 is relatively soft. When the lamp beads 22 of the LED lamp 2 are arranged dispersedly and the LED lamp 2 is used for supplementary lighting, it is easy to cause uneven illumination and affect the supplementary lighting effect. The spectral distribution of the xenon lamp 3 is close to sunlight, that is, the xenon lamp 3 has a relatively strong illumination ability. Placing the projection of the lamp tube 31 in the axial direction of the housing 1 outside the lamp bead 22 does not affect the illumination uniformity.

[0051] In an embodiment, part of the projection of the lamp tube 31 in the axial direction of the housing 1 is located on the projection of the lamp board 21 in the axial direction of the housing 1, that is, the dimension of the lamp tube 31 in the radial direction of the housing 1 is small, making the structure between the xenon lamp 3 and the LED lamp 2 more compact. In other embodiments, the projection of the lamp tube 31 in the axial direction of the housing 1 can also be entirely located outside the lamp board 21.

[0052] In Figure 5 In the illustrated embodiment, the lamp board 21 of the LED lamp 2 is quadrilateral, and a plurality of lamp beads 22 are respectively distributed in the middle of the lamp board 21 and near the four corners. The xenon lamp electrode 32 is located outside the side of the quadrilateral, and the projection of the lamp tube 31 in the axial direction of the housing 1 coincides with the top corner position of the lamp board 21. With such a setting, while ensuring an installation space between the xenon lamp electrode 32 and the lamp board 21, the projection position of the lamp tube 31 in the axial direction of the housing 1 is closer to the lamp beads 22 of the LED lamp 2, making the light-emitting area of the xenon lamp 3 coincide with the light-emitting area of the LED lamp 2, and when the xenon lamp 3 and the LED lamp 2 work simultaneously, the illumination is more uniform, and the structure between the xenon lamp 3 and the LED lamp 2 is also more compact.

[0053] In other embodiments, the lamp board 21 can also be circular. In this embodiment, while ensuring an installation space between the xenon lamp electrode 32 and the lamp board 21, the inner diameter of the lamp tube 31 is relatively larger than the structure of the above embodiment, and the uniformity of illumination decreases.

[0054] In other embodiments, the projection of the lamp tube 31 in the axial direction of the housing 1 is located outside the lamp board 21. In this embodiment, compared with the above embodiment, the inner diameter of the lamp tube 31 is larger, and the uniformity of illumination decreases.

[0055] In other embodiments, the length direction of the lamp tube 31 can also be arranged along the axial direction of the housing 1. For example, the lamp tube 31 and the xenon lamp electrode 32 are located on the same straight line, or the lamp tube 31 is spiral and extends along the axial direction of the housing 1.

[0056] Refer to Figure 2 and Figure 4 , the flash lamp further includes a reflector cup 4. The reflector cup 4 is arranged in the accommodation cavity 11 and is connected to the circuit board 5. The reflector cup 4 is conical, and the light generated by the lamp tube 31 and the lamp beads 22 are both located within the reflector cup 4. The light generated by the lamp tube 31 and the lamp beads 22 is radial. Through the arrangement of the reflector cup 4, the reflector cup 4 can reflect the light of the LED lamp 2 and the xenon lamp 3 out of the light outlet of the accommodation cavity 11, so that the light of the LED lamp 2 and the xenon lamp 3 can both irradiate the object photographed by the camera, and the light is made more concentrated, improving the lighting effect.

[0057] In Figure 4 the illustrated embodiment, the bottom of the reflector cup 4 is fixedly connected to the side of the circuit board 5 facing the light outlet, and the bottom of the reflector cup 4 is provided with a first avoidance hole and a second avoidance hole at intervals. The lamp board 21 is located within the first avoidance hole, enabling the lamp beads 22 to be connected to the circuit board 5 through the lamp board 21. The xenon lamp electrode 32 penetrates through the second avoidance hole and is fixed on the circuit board 5, and realizes the electrical connection between the xenon lamp 3 and the circuit board 5. In other embodiments, the reflector cup 4 is fixed to the circumferential housing of the circuit board 5, so as not to affect the installation of the LED lamp 2 and the xenon lamp 3.

[0058] Refer to Figure 2 , the flash lamp further includes an optical element 7. The optical element 7 is arranged at the light outlet of the accommodation cavity 11 and is located on the light paths of the LED lamp 2 and the xenon lamp 3. The optical element 7 can adjust the light effects of the LED lamp 2 and the xenon lamp 3.

[0059] In one embodiment, the optical element 7 is a focusing lens. When the light generated by the lamp tube 31 and the light generated by the lamp beads 22 pass through the focusing lens, refraction occurs, thereby achieving light concentration.

[0060] In one embodiment, the optical element 7 is a light-shielding sheet for adjusting the light transmittance. When the light generated by the lamp tube 31 and the light generated by the lamp beads 22 pass through the light-shielding sheet, the light-shielding sheet can change the chromaticity, thereby achieving the adjustment of the lighting chromaticity. According to needs, light-shielding sheets with different light transmittances can be replaced.

[0061] In one embodiment, the optical element 7 is a light-blocking sheet with through holes. When the light generated by the lamp tube 31 and the light generated by the lamp beads 22 pass through the light-blocking sheet, they can only pass through the light-blocking sheet, thereby projecting a light spot with the same shape as the through holes, improving the shooting light and shadow effect. According to needs, light-blocking sheets with different through hole shapes can be replaced.

[0062] In one embodiment, the optical element 7 is a combination of two or three of the above-mentioned focusing lens, light-shielding sheet, and light-blocking sheet.

[0063] Refer to Figure 2 and Figure 6 , the flash lamp further includes a driving mechanism 6, and the driving mechanism 6 is fixed on the housing 1. The movable end of the driving mechanism 6 is connected to the LED lamp 2 and the xenon lamp 3, and the driving mechanism 6 can drive the LED lamp 2 and the xenon lamp 3 to move in a direction close to or away from the light outlet, thereby adjusting the lighting effect of the flash lamp.

[0064] Wherein, when the driving mechanism 6 drives the LED lamp 2 and the xenon lamp 3 to move in a direction close to the light outlet, less light is blocked by the housing 1, that is, the light-emitting angles of the LED lamp 2 and the xenon lamp 3 that can emit out of the light outlet are larger, and thus the area of the formed light spot is larger. When the driving mechanism 6 drives the LED lamp 2 and the xenon lamp 3 to move in a direction away from the light outlet, more light is blocked by the housing 1, that is, the light-emitting angles of the LED lamp 2 and the xenon lamp 3 that can emit out of the light outlet are smaller, and thus the area of the formed light spot is smaller.

[0065] In the embodiment where the optical element 7 is a focusing lens, when the driving mechanism 6 drives the LED lamp 2 and the xenon lamp 3 to move in a direction close to or away from the light outlet, the incident angle of the light on the focusing lens is changed, thereby realizing the adjustment of the size of the light spot. Moreover, when the light spot is smaller, the light is more concentrated and the illumination brightness is also brighter.

[0066] In Figure 2 the shown embodiment, the circuit board 5, the reflector cup 4, the LED lamp 2, and the xenon lamp 3 are fixed together, so the circuit board 5, the reflector cup 4, the LED lamp 2, and the xenon lamp 3 move together under the drive of the driving mechanism 6.

[0067] In one embodiment, the driving mechanism 6 includes a screw 62 and a driving motor 63. The screw 62 is rotatably connected to the housing 1 and is arranged along the axial direction of the housing 1. The circuit board 5 is threadedly connected to the screw 62. The driving motor 63 is connected to the housing 1 and is in transmission connection with the screw 62, and the driving motor 63 can drive the screw 62 to rotate around its own axis.

The sliding bearing is slidably sleeved on the guide rod, and the guide rod is fixed to the circuit board 5.

[0071] Please refer to Figure 1 , in some embodiments, the flash can be a top-mounted flash. The body 8 of the top-mounted flash is rotatably connected to the housing 1 through a rotating shaft 9, so that the housing 1 and the structures connected to the housing 1 can perform pitching rotation on the body 8, thereby changing the light-emitting angle of the flash, and further improving the usability of the flash.

[0072] In some other embodiments, the flash can be a studio flash or an outdoor flash; its body 8 and the housing 1 can be an integral structure, or can be a structure of two independent shells. The housing 1 can rotate on the body 8, or the housing 1 can be fixedly connected to the body 8.

[0073] In some embodiments, refer to Figure 2 , the body 8 is provided with a battery 81. The battery 81 is electrically connected to the circuit board 5 and the driving motor 63.

[0074] The flash lamp of the present application includes an LED lamp 2 and a xenon lamp 3. The LED lamp 2 can provide soft illumination for the object to be photographed, and the xenon lamp 3 can provide high-brightness illumination for the object to be photographed. Therefore, through the arrangement of the LED lamp 2 and the xenon lamp 3, the flash lamp can not only provide soft illumination for the object to be photographed, but also provide high-brightness illumination for the object to be photographed. Moreover, the LED lamp 2 and the xenon lamp 3 can be used simultaneously for fill light to increase the chroma of the fill light, so that the flash lamp can adapt to different brightness shooting scenes, and only the corresponding lamp needs to be turned on according to the needs during use, making it convenient to use. Among them, the xenon lamp 3 is arranged on the optical path of the LED lamp 2, and the light-emitting area of the LED lamp 2 coincides with the light-emitting area of the xenon lamp 3, so that the spot positions generated by the LED lamp 2 and the xenon lamp 3 in the flash lamp are the same, thereby making the light output of the flash lamp more uniform.
