Background technique:

The traditional luminous body is made of glass tube or hard material tube, which is processed and bent into the required shape, and inert gas is filled in it, and the electric current is connected to make it generate discharge and light up; or it is installed in the desired luminous body. Insert light bulbs, light-emitting diodes, etc. to make them emit light of various colors. This kind of traditional light tube has high manufacturing cost, troublesome molding, and cannot be fixed to change the shape at any time. It will be broken and damaged when it is heated and exposed to water (such as rainwater) or impacted. The same light tube can only emit a single color. The tube shape and size cannot be reduced or changed arbitrarily, and there is a lack of energy consumption. Besides, if you want to present different shapes, you must use molds to shape them in advance, or use them together or connect them with brackets. Production and use costs.

At present, it is very common for luminous strips or light guide strips to achieve display or lighting occasions or objects. For example, in vehicles, in order to reduce the luminous display function required by poor sight or insufficient environmental lighting, common people have the luminous or light guide strips. It is installed on a frame to generate light reflection or light flashing to warn its surroundings or people and vehicles on the road. It is also used on advertising boards, installed on body anti-collision display devices, and installed on personal wearables , helmets, and simple mobility tools (such as locomotives or bicycles); however, due to the high cost of the above-mentioned manufacturing and the small adjustable variability of the shape, the adoption rate of the overall product is not high, such as warning signs on the road At present, low-cost reflective cursor buttons are still mostly used, or low-light light sources flicker to show that the warning effect is limited, especially for high-speed vehicle drivers. The warning effect will be greatly reduced; pedestrians on the road rarely wear The safety warning device that generates light display independently makes pedestrians often encounter accidents caused by collisions with other vehicles due to insufficient self-display in outdoor environments with insufficient lighting.

In addition, in daily life, we often encounter occasions that require convenient portable lighting or display of location, and are not limited to the display type in use, but there is no one that is convenient to use and can be adjusted with the user according to any needs. It is a pity for items that can freely change the display or lighting type according to their preferences.

Therefore, how to provide a self-luminous device with low cost and high light display and adjustable application type is one of the conditions that must be supported in advance when the above-mentioned problems are to be solved.

Moreover, the traditional lighting strips or light guide strip devices are all made of flexible transparent materials, which are not self-supporting. Therefore, they need to rely on other solid supports or frames to assist their intended weaving. However, such additional supports or racks not only increase the manufacturing cost of the overall applied article, but also often cause obstruction or damage to the shape design, and it is obvious that the overall volume and weight are relatively increased, greatly Affects its portability, so there is a need to improve it.
