I. Overview
LED lighting is getting more and more sought after by the market. Now the city's lighting project has basically eliminated neon lights and used LED lights to make them. Among them, the application of the guardrail tube is particularly extensive. For example, the lighting of each overpass in Chengdu uses a large number of LED guardrail tubes, which not only decorate the city, but also illuminate the bridge body, making the entire overpass more magnificent and elegant. However, since the birth of the self-defense tube, there have been various quality problems. In addition to the low-cost bidding strategy of the government and other owners, the producer lacks a system on the basis of component selection and circuit design. The understanding does not solve the quality problem of the guardrail tube in theory and practice, and also lacks a strict supervision system for good construction and acceptance. The practitioners do not pay attention to development, and only low-price competition leads to the widespread quality of the barrier pipe in the market. Inferior, seriously ruined the reputation of the LED guardrail tube. At present, the vast majority of LED guardrail tube manufacturers in China have accumulated too little experience. The lack of investment in research and development is an important factor, and many of them are in the rough of home workshops. This article will introduce the reliability of the guardrail tube and our solutions to these problems from several aspects. I hope that some valuable reference and reference can be given to the barrier manufacturers, lighting engineering companies and owners, and the LED guardrails can be reversed. The bad impression of the tube reshapes its good real image.
Second, the use of guardrail tube
LED guardrail lights are widely used in overpasses, rivers, highways, gardens, building outlines, large advertising signs, pedestrian bridges, dance halls, bars, karaoke halls, etc., which are ideal for beautifying the urban environment. The length of the guardrail tube is generally determined according to the requirements of the user.
Third, the technical parameters of the guardrail tube
LED guardrail lights are available in monochrome, two-color, and colorful colors. They can be controlled by microcomputer or circuit to achieve various colorful changes such as gradation, jump, color flicker, random flicker, gradual alternation, running chase, and fixed color. The running parameters of each pattern can be independently configured, the automatic running mode can be edited, and the specified pattern can be selected. It can simultaneously control the lighting of dozens to thousands of LED guardrail tubes, automatically store setting parameters, and reload preset parameters. The number of LEDs in a general guardrail tube is: 96/108/144. At present, the shape is mainly D-shaped tube. Use voltage: DC 12V/24V/36V and AC 220V.
Fourth, the choice of guardrail tube components
1, light beads:
LED beads are definitely the most important device in the guardrail tube and are also of the highest value. LED beads must be selected from regular manufacturers. In our experience, chips with 12 micron or more are definitely better than 9 micron chips. This is mainly because the heat dissipation is better, and the light attenuation and reliability are much better, but the average user cannot detect it. . Chengdu Wenjian Electronics Co., Ltd. is engaged in the production of LED light bead. In addition to the chip, other auxiliary materials companies are also strictly selected, which can guarantee the quality of the produced bead, and the quality of the guardrail tube will be improved from the source.
