Flaring flash lamp

Abstract

The utility model provides a flared flash lamp, which relates to the technical field of photographic flash lamps and comprises a lamp base serving as a support component of the flash lamp. The bottom of the umbrella-shaped glass lampshade is fixedly connected to the top of the lamp base, and a light transmitting part of the umbrella-shaped glass lampshade expands outwards to form an umbrella-shaped structure; the spiral flaring-shaped flash lamp tube spirally extends along the inner surface of the umbrella-shaped glass lampshade, and the spiral track of the spiral flaring-shaped flash lamp tube is coaxially matched with an umbrella-shaped flaring of the umbrella-shaped glass lampshade, so that the problems that the conventional flash lamp generally adopts a straight barrel-shaped or small-angle light emitting structure design, the light emitting direction of a light emitting source is relatively concentrated, and the angle is fixed are solved. When the flash lamp is used in cooperation with the light reflecting umbrella, the umbrella cover area close to the light outlet of the flash lamp is close to the bulb, and the umbrella cover edge area away from the light outlet is far away from the bulb. The uniformity of a light field formed after the light is reflected by the light reflecting umbrella is poor, and the shooting or lighting effect is influenced.

Description

Technical Field

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

[0002] In photography, film and television shooting, and various lighting scenarios, flash units serve as important supplementary lighting devices, and the uniformity of their light output directly affects image quality and lighting effects. To soften the light and expand the illumination range, current technologies often use flash units in conjunction with reflectors. The reflectors reflect and diffuse the light emitted by the flash unit to obtain a softer and wider illumination field.

[0003] However, commonly used traditional flash units typically employ a cylindrical or narrow-angle light-emitting structure, resulting in a relatively concentrated and fixed angle of light emission from the bulb. When this type of flash unit is used in conjunction with a reflector, the distance between the bulb and different areas of the reflector surface varies significantly due to the bulb's position and emission angle: the area closer to the flash's output is closer to the bulb, while the edge areas further away are farther. This unevenness in spacing leads to inconsistent light intensity received by different areas of the reflector, with stronger light near the bulb and weaker light at the edges. Consequently, the resulting light field after reflection is less uniform, exhibiting localized overexposure or underexposure, thus affecting the shooting or lighting results.

[0004] Especially in scenarios requiring high uniformity of the light field, such as product photography and portrait photography, the aforementioned shortcomings of traditional flash units combined with reflectors are particularly pronounced. This often necessitates additional auxiliary equipment or complex adjustment processes to compensate for uneven light field, increasing equipment costs and reducing work efficiency. Therefore, designing a flash unit structure that can be used with a reflector and achieve a more uniform distance between the bulb and the reflector surface, thereby effectively improving light field uniformity, has become a pressing technical problem to be solved in this field.

[0006] 1. The technical problem to be solved by the utility model:

[0007] This utility model provides a flared flash lamp to solve the technical problems existing in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the technical solution provided by this utility model is: a flared flashlight, comprising...

[0010] The lamp base serves as a support component for the flash lamp;

[0011] An umbrella-shaped glass lampshade, the bottom of which is fixedly connected to the top of the lamp base, and the light-transmitting part of the umbrella-shaped glass lampshade expands outward to form an umbrella-shaped structure;

[0012] A spiral flared flash tube extends spirally along the inner surface of the umbrella-shaped glass lampshade, and its spiral trajectory is coaxially matched with the umbrella-shaped flare of the umbrella-shaped glass lampshade.

[0013] In this embodiment, the device can be used in conjunction with a reflective umbrella; please refer to [reference needed]. Figure 1 When the spiral flared flash tube is powered on, it emits light, causing the light to diffuse outward along the spiral path. The flared structure of the umbrella-shaped glass lamp cover further scatters the light emitted by the spiral tube. This device is installed on a reflector umbrella. Due to the combination of the umbrella-shaped glass lamp cover and the spiral flared flash tube, the emitted light is softer after being reflected by the reflector umbrella, and the light field formed after reflection by the reflector umbrella has good uniformity.

[0014] Furthermore, the angle between the extension direction of the umbrella-shaped glass lampshade and the spiral flared flash tube and the central axis is α, the reflective surface of the reflective umbrella faces the opening direction of the umbrella-shaped glass lampshade, and the angle between its sidewall and the central axis is β, where |α-b|≤10°.

[0015] Furthermore, the spiral flared flash tube has 2-7 turns.

[0016] Furthermore, the spiral pitch of the spiral flared flash tube is 1 / 5 to 1 / 3 of the lampshade height, and the spiral axis coincides with the flared axis of the lampshade.

[0017] Furthermore, the spiral flared flash tube is a xenon lamp tube, with brackets at both ends and electrodes extending into the lamp base and connected to an external power source.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0020] This utility model features a reasonable design. Through the unique synergistic design of a spiral-shaped, flared flash tube and an umbrella-shaped glass lampshade, it effectively solves the problem of uneven light distribution when traditional flash units are used with reflectors. The spiral tube extends 2-7 times along the inner surface of the lampshade, ensuring uniform light coverage from the center to the edge, avoiding the overly bright center and dark edges phenomenon caused by traditional single-circle tubes. Simultaneously, the flared structure of the lampshade matches the angle of the reflector (|ab|≤10°), resulting in a more uniform light field after reflection, making it particularly suitable for portrait and still life photography scenarios where high light uniformity is required.

[0021] The number of turns and spacing of the spiral lamp tubes can be adjusted according to shooting needs: a 2-3 turn design is suitable for high-efficiency fill lighting at small angles (such as macro photography), while a 5-7 turn layout is suitable for large-area uniform lighting (such as portrait or scene shooting). The lamp tube spacing is optimized to 1 / 5-1 / 3 of the lampshade height to avoid local overheating or light discontinuity caused by overlapping light paths, thus improving energy utilization. In addition, the spiral discharge structure of the xenon lamp tubes, combined with the scattering effect of the glass lampshade, makes the light softer, reducing the need for post-processing.

[0022] 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

[0031] It should be noted that structures not described in this invention do not involve the design points and improvement directions of this invention, and can all be achieved using existing technologies known to those skilled in the art.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] See attached document Figure 1-2 A flared flash unit, including

[0034] The lamp base 1 serves as a support component for the flash lamp;

[0035] The umbrella-shaped glass lampshade 2 is fixedly connected to the top of the lamp base 1 at its bottom, and the light-transmitting part of the umbrella-shaped glass lampshade 2 expands outward to form an umbrella-shaped structure.

[0036] The spiral flared flash tube 3 extends spirally along the inner surface of the umbrella-shaped glass lampshade 2, and its spiral trajectory is coaxially matched with the umbrella-shaped flare of the umbrella-shaped glass lampshade 2.

[0037] In this embodiment, the device can be used in conjunction with a reflective umbrella; please refer to [reference needed]. Figure 1 When the spiral flared flash tube 3 is powered on, it emits light, causing the light to diffuse outward along the spiral path. The flared structure of the umbrella-shaped glass lamp cover 2 further scatters the light emitted by the spiral tube. This device is installed on a reflector umbrella. Due to the cooperation between the umbrella-shaped glass lamp cover 2 and the spiral flared flash tube 3, the emitted light is softer after being reflected by the reflector umbrella, and the light field formed after being reflected by the reflector umbrella has good uniformity.

[0038] The angle between the extension direction of the umbrella-shaped glass lampshade 2 and the spiral flared flash tube 3 and the central axis is α. The reflective surface of the reflector faces the opening direction of the umbrella-shaped glass lampshade 2, and the angle between its sidewall and the central axis is β, where |a-b|≤10°. In this embodiment, the device is adapted to a reflector. The connection between the flash and the reflector uses existing technology, which will not be described in detail here. By limiting the angles α and β, the light output effect of the reflector is improved.

[0039] The spiral flare tube 3 has 2-7 turns. In this embodiment, 2-3 turns are suitable for small-angle floodlight, with higher light efficiency, and are suitable for close-range fill light, such as macro photography.

[0040] 5-7 rings: Suitable for wide-angle uniform lighting, with a wider light coverage, suitable for portrait or scene shooting. Traditional ring flashes only have a single ring tube, with high brightness in the center and obvious attenuation at the edges; the flared spiral structure of this application, through multiple rings, allows the light to be superimposed multiple times inside the lampshade, resulting in better lighting effects.

[0041] The spiral spacing of the spiral flared flash tube 3 is 1 / 5 to 1 / 3 of the height of the lamp cover, and the spiral axis coincides with the flared axis of the lamp cover. In this embodiment, through multiple experiments and demonstrations, it was found that if the spacing is too small, it will lead to excessive overlap of the light path and local overheating; if the spacing is too large, the light distribution will be discontinuous and dark areas will be formed. This limitation ensures that the light spots of adjacent spirals overlap 30% to 50% on the light-transmitting surface of the lamp cover, eliminating dark areas and avoiding energy waste.

[0042] The spiral flared flash tube 3 is a xenon lamp tube. It has supports at both ends and is connected to electrodes that extend into the lamp base 1 and are connected to an external power source. The spiral structure makes the discharge arc evenly distributed, and when combined with the umbrella-shaped lamp cover, it can obtain a softer light quality than a straight tube xenon lamp.

[0043] 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.
