Solution Overview
Problem
Existing tube lights emit hard light that fails to meet the requirements of modern photographic equipment, leading to uneven light distribution and unsuitable photographic effects in scenarios like live broadcasts and wedding photography.
Innovation Solution
An airbag tube light design featuring a reflective cover, inflatable airbag with soft and light-transmitting surfaces, and tube lights that scatter light through a curved soft surface to achieve a soft light effect, enhancing illumination area and evenness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional tube light is used, then the light emission intensity is high, but the light quality is hard light which does not meet photographic requirements
Solution Approach 1:
An airbag is introduced as an intermediary component between the tube light and the photographed object. The airbag receives the hard light from the tube light and transforms it into soft light through its translucent surface, thereby mediating the light quality to meet photographic requirements while maintaining high illumination intensity
Solution Approach 2:
The patent changes the physical state and optical parameters of the light by introducing the airbag with its translucent surface. This transforms the light characteristics from hard to soft, altering the diffusion angle and light distribution parameters to achieve desired photographic effects
2Device complexity
If traditional tube light is used, then the structure is simple, but the light distribution is uneven with bright and dark striped regions
Solution Approach 1:
The airbag acts as a light-distributing intermediary that receives uneven light from the tube light and redistributes it uniformly through its translucent surface, eliminating bright and dark striped regions while adding minimal structural complexity
Solution Approach 2:
The airbag is designed with a curved surface that helps distribute light more evenly in all directions, reducing the formation of bright and dark stripes and improving overall light distribution uniformity
3Area of stationary object
If traditional tube light is used, then the illumination area is limited, but the illumination angle is narrow
Solution Approach 1:
The airbag transforms the light parameters by increasing the illumination angle through its translucent surface properties, allowing light to spread over a wider area and thereby expanding the effective illumination coverage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The airbag tube light provides a softer and more evenly distributed light, improving photographic effects by enlarging the illumination angle and area, and eliminating bright and dark striped regions, making it suitable for photography and video recording.
Implementation Method 1
a reflective cover, provided with an accommodation cavity, where the accommodation cavity is provided with an opening at an end of the reflective cover, and an inner side of the reflective cover is a reflective surface
Implementation Method 2
a side of the main body portion includes a soft light surface and a light-transmitting surface opposite to each other... the light-transmitting surface of the tube light faces the light-transmitting surface of the airbag, to make light emitted by the tube light pass through the light-transmitting surface and then emitting out from the soft light surface, to realize a scattering of the light
