Description

Technical Field

[0001] This utility model mainly relates to the field of flash technology, specifically to a spiral composite photographic flash. Background Technology

[0002] In professional photography, flash units are one of the core devices for controlling light and improving image quality. Traditional photographic flash units mainly consist of two types: stick flash tubes and ring flash tubes. However, current technology has the following drawbacks:

[0003] Rod-shaped flash tubes (such as straight-tube xenon flash tubes) have a limited beam angle and uneven light distribution, resulting in a loss of luminous efficiency. In addition, their single light source direction makes it difficult to meet the needs of multi-angle lighting.

[0004] While ring flash tubes can provide a surround lighting effect, their planar ring structure results in insufficient depth of light emission, leading to a smaller coverage area in the depth direction, which can easily cause shadow breaks, especially when shooting three-dimensional objects. Furthermore, the longer arc length of a ring flash tube results in trigger delay and increased energy consumption.

[0005] Furthermore, traditional flash units lack a constant auxiliary light function, making it impossible for photographers to visually judge the angle of light and the distribution of shadows before the flash. They can only rely on experience or test shots to make adjustments, which is inefficient.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 1. The technical problem to be solved by the utility model:

[0008] This utility model provides a spiral composite photographic flash to solve the technical problems existing in the background art.

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is: a spiral composite photographic flash, comprising...

[0011] The spiral flash tube has a spiral structure that forms a multi-angle light-emitting surface in the axial and radial directions, which allows the light to be evenly dispersed in all directions.

[0012] A constant-on light tube is fixedly installed on the top of the spiral flash tube to provide continuous modeling light and indicate the flash path, providing continuous illumination and facilitating lighting confirmation before shooting;

[0013] A transparent glass lampshade, with its bottom sealed to a transparent glass base, houses and protects the spiral flash tube and the constantly lit tube.

[0014] The transparent glass base has an electrode interface for electrical connection and support of the spiral flash tube and the constant-on tube, while providing a stable mounting base.

[0015] In this embodiment, a standard reflector umbrella interface is provided at the bottom of the transparent glass base for connecting a photographic reflector umbrella. This device is installed at the center of the photographic reflector umbrella via the transparent glass base. The spiral flash tube generates a high-intensity flash after being powered on. Its unique spiral structure allows the light to diffuse evenly, while axial extension ensures sufficient light-emitting depth. If it is necessary to check the lighting effect before shooting, the constantly lit tube can be turned on to continuously emit light, clearly displaying the lighting effect before shooting. The combination of the transparent glass lampshade and the base not only provides physical protection but also enhances the light reflection efficiency through the high light transmittance of the glass material and the inner surface coating. During operation, the photographer first checks the light path and shadow distribution through the constantly lit tube, then turns off the constantly lit tube before shooting. During shooting, the spiral flash tube emits light instantly, and its multi-angle light emission characteristics, combined with the reflector umbrella, create a soft and uniform lighting effect, solving the problems of the single angle of traditional rod-shaped tubes and insufficient depth of ring-shaped tubes, significantly improving lighting efficiency and shooting quality.

[0016] Furthermore, the spiral flash tube has 2-7 turns, and the spiral spacing is 1.5-3 times the diameter of the tube.

[0017] Furthermore, the spiral flash tube is a xenon lamp tube, and its electrodes extend into the interior of the transparent glass base to connect to an external power source.

[0018] Furthermore, the constantly lit lamp tube has a concave structure, and its electrodes extend through a support column into the transparent glass base to connect to an external power source.

[0019] Furthermore, the transparent glass base is provided with heat dissipation holes for heat dissipation of the lamp tube.

[0020] Furthermore, the transparent glass lampshade has a cylindrical structure.

[0021] 3. Beneficial effects:

[0022] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0023] This utility model has a reasonable design. In terms of optical performance, the spiral flash tube achieves uniform light emission from multiple angles in the axial and radial directions through a multi-turn spiral structure design. Combined with the high light transmittance of the transparent glass lamp cover, it improves the light utilization rate.

[0024] The combination of spiral flash tubes and constant-on tubes ensures flash output at standard color temperature while enabling precise light effect preview through constant-on tubes, solving the core pain points of traditional flash lighting, such as limited light output and difficulty in previewing.

[0025] In terms of structural design, the integrated transparent glass base increases the light transmittance at the bottom, thereby improving the lighting effect of the flash.

[0026] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0036] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0037] See attached document Figs. 1-2 A spiral compound photographic flash, including

[0038] The spiral flash tube 1 has a spiral structure that forms a multi-angle light-emitting surface in the axial and radial directions, which allows the light to be evenly diffused in all directions.

[0039] The constant-on light tube 2 is fixedly installed on the top of the spiral flash tube 1 to provide continuous modeling light and indicate the flash path, providing continuous illumination and facilitating lighting confirmation before shooting.

[0040] The transparent glass lampshade 3 is sealed to the bottom of the transparent glass base 4, and internally accommodates and protects the spiral flash tube 1 and the constantly lit tube 2.

[0041] The transparent glass base 4 is equipped with an electrode interface for electrically connecting and supporting the spiral flash tube 1 and the constant-on tube 2, while providing a stable mounting base.

[0042] In this embodiment, the bottom of the transparent glass base 4 is equipped with a standard reflector umbrella interface for connecting a photographic reflector umbrella. This device is installed at the center of the photographic reflector umbrella via the transparent glass base 4. After the spiral flash tube 1 is powered on, it produces a high-intensity flash. Its unique spiral structure allows the light to diffuse evenly, while axial extension ensures sufficient light-emitting depth. If it is necessary to confirm the lighting effect before shooting, the constant-on tube 2 is turned on to continuously emit light, clearly displaying the lighting effect before shooting. The combination of the transparent glass lampshade 3 and the base not only provides physical protection, but also enhances the light reflection efficiency through the high light transmittance of the glass material and the inner surface coating. During operation, the photographer first confirms the light path and shadow distribution through the constant-on tube 2, then turns off the constant-on tube 2 before shooting. During shooting, the spiral flash tube emits light instantly, and its multi-angle light emission characteristics, combined with the reflector umbrella, form a soft and uniform lighting effect, solving the problems of the single angle of traditional rod-shaped tubes and insufficient depth of ring-shaped tubes, significantly improving lighting efficiency and shooting quality.

[0043] The spiral flash tube 1 has 2-7 turns, and the spiral spacing is 1.5-3 times the tube diameter. In this embodiment, the spiral flash tube 1 adopts a spiral design of 2-7 turns. Experiments have verified that this range can provide the best light coverage and luminous efficiency while ensuring structural compactness. The spiral spacing is set to 1.5-3 times the tube diameter, which can ensure that the light between adjacent spiral turns does not interfere with each other and maintain good structural strength. This specific parameter combination enables the flash to produce a softer and more uniform lighting effect when used with a reflector umbrella, which is particularly suitable for applications with high light quality requirements such as portrait photography and product photography.

[0044] The spiral flash tube 1 is a xenon lamp tube, with its electrodes extending into the transparent glass base 4 and connected to an external power source. In this embodiment, the spiral flash tube 1 uses xenon lamp technology, which features high luminous intensity and stable color temperature, making it particularly suitable for professional photography needs. The electrodes at both ends of the tube extend into the transparent glass base 4 via high-temperature resistant wires and are connected to the integrated power interface of the transparent glass base 4. This built-in electrode arrangement ensures the reliability of the electrical connection and avoids interference from exposed electrodes on the light distribution. In actual operation, when an external trigger signal is input through the power interface of the base, the xenon lamp tube can complete the discharge and emission within microseconds. Its spiral structure allows the light generated by the xenon discharge to be evenly diffused through the multi-angle luminous surface. At the same time, the circuit board and control device inside the transparent glass base 4 are positioned as centrally as possible, so that the light emitted by the spiral flash tube 1 can be emitted outward along the outer ring of the transparent glass base 4. The special design of the transparent glass base 4 provides good insulation protection and light transmission for the high-voltage circuit, ensuring safe use and good lighting effects.

[0045] The constantly lit lamp tube 2 has a concave structure, and its electrodes extend to the inside of the transparent glass base 4 through the support columns to connect to an external power source. In this embodiment, the electrodes at both ends of the lamp tube extend to the transparent glass base 4 through the internal support columns. Conductive paths can be set on the support columns, or metal support columns can be used directly to power the constantly lit lamp tube 2. In practical applications, the constantly lit lamp tube 2 can use low-voltage LED array, fluorescent constantly lit lamp tube, halogen constantly lit lamp tube and xenon constantly lit lamp tube technology, and the constant current drive circuit built into the base ensures the stability of light emission.

[0046] The transparent glass base 4 is provided with heat dissipation holes 41 for heat dissipation of the lamp tube. In this embodiment, heat dissipation holes 41 are opened in the middle of the transparent glass base 4 to form an effective air convection channel. In actual operation, when the flash lamp works continuously, the heat generated by the spiral flash tube 1 and the concave constant light tube 2 will be transferred to the transparent glass base 4 through heat conduction, and the heat dissipation holes 41 will perform heat dissipation.

[0047] The transparent glass lampshade 3 has a cylindrical structure. In this embodiment, the transparent glass lampshade 3 is made of tempered glass material with high light transmittance. The inner diameter of its cylindrical structure maintains a gap of 5-8 mm with the outer diameter of the spiral flash tube 1, ensuring sufficient light diffusion while avoiding mechanical interference. The wall thickness of the lampshade is preferably 3-5 mm to achieve optimal light transmission while ensuring structural strength. An anti-reflective coating can be selectively applied to the inner surface of the lampshade to further reduce light loss.

[0048] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
