Problems solved by technology

[0004] To sum up, the previous luminous sticks are only continuously improving the luminescent materials and color effects, and none of them have the performance or effect of displaying dynamically variable text or graphics.
However, the existing luminous signs using LEDs only use a multi-row and multi-column LED dot matrix to express a text or graphic, which lacks flexibility.
A dynamic, variable application of LED technology to glow sticks is missing from the prior art

Embodiment Construction

[0011] The present invention aims to design a light stick based on LED (light emitting diode) that can naturally display dynamic and variable characters or graphics in the air, and has two technical innovations:

[0012] (1) For the first time, LED display technology is applied to light sticks, so that simple light sticks can display dynamic and variable

[0013] Text or graphics, and can be easily modified or switched display content.

[0014] (2) It is proposed to use a single row of LED strings (generally 16) to generate dynamic text in natural movement (swing or rotation).

[0015] New LED display technology for words or graphics. After more than 20 years of development, the LED display industry has matured. Its design principle has always been based on static LED dot matrix arrangement and dynamic row / column scanning. In reality, there are already a large number of products and popular mature technologies. The single row scanning technology proposed by the present inve...

Abstract

The invention provides a LED glow stick, which comprises a transparent stick shell with a LED string and a power supply. The LED string is coupled with a control circuit which comprises a memory for memorizing the array of characters and graphics needed to be shown. A central processing unit which is coupled with the memory can take out the array of characters and graphics needed to be shown form the memory, and can output to the LED string line by line or row by row; so, at a certain moment, the LED string only shows one line or one row of the array of characters and graphics needed to be shown. The LED glow stick is manually operated, thereby responding to the manual swing and rotation of the LED glow stick and completely show the array of characters and graphics needed to be shown. The invention has the beneficial effects that a single line LED can show the glow charters; no motor is used in the method; the single line LED can be shown during naturally moving; the shown characters and graphics are rich and dynamic and so on.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a light-emitting stick which can display dynamic text or graphics by using a single row of LEDs, which can be used as a pull-up stick for spectators or a toy for children. Background technique [0002] There are many varieties and styles of luminous sticks, and they are widely used. The common ones are luminous pull sticks and luminous plastic sticks used as children's toys. Although there are various materials and styles of sticks, the essential technology lies in the principle of light emission. From this point of view, light sticks can be roughly divided into two categories: chemical material light emission and electroluminescence. LED light sticks should belong to the electroluminescent category. In all the patent searches on related terms such as light-emitting sticks, electronic light-emitting sticks, pulling sticks, LED sticks, etc., there is only one patent document fo...
