Graphic common types of traffic road signs

15 pm, invited the legal publicity brigade traffic police detachment Liang Jiao guest studio host,solar led traffic sign interpret common traffic signs information to users. Liang Jiao on guide signs, warning signs, directional signs and traffic signs prohibition signs four categories, combining a detailed interpretation of the drawing board.Road congestion is inevitable phenomenon occurs every city, in addition to cars, narrow roads and other objective factors, some sections of congestion is more human. Recently,traffic road sign , some friends in a website forum posting, say less likely to recognize the signs, hoping to learn relevant knowledge. 

Plastic products production process

The key link of plastic molding plastic products processing production. Plastics will be in various forms (powder, granular, solution or dispersion) made the required shape products or blank. As many as 30 kinds of molding method. It depends mainly on the type selection of plastic (thermoplastic or thermosetting), the initial shape and the shape and size of products. Plastic processing method of thermoplastic plastics are commonly used extrusion magnetic beacon lights, injection molding, blow molding, calendering and heat molding, plastic processing, thermosetting plastic molding, transfer molding is generally adopted, but also for injection molding. Laminated, molding and thermoforming is made of plastic molding in the plane. The above method of plastic processing, can be used in rubber processing. In addition, there are in a liquid monomer or polymer as the raw material beacon flashing lights of casting. In these methods, by extrusion and injection molding is used at most, and it is also the most basic forming method.

The production of plastic products generally include plastic material, molding, machining, joining, modification and assembly etc.. Four months battery powered warning lights after the procedure is carried out in the plastic has been formed into products or semi products after, also known as the two plastics processing.

What is electronic flash

HD LED lightning series of intelligent digital traffic wand flashlight on the continent focus on optoelectronic field of intelligent transportation systems for a variety of capture and development, security mount, capture speeding, running red lights and other electronic police work environment and functional requirements and developed a new high-power high-performance digital pulse LED flash. The product uses a unique digital control circuit,barricade flashing light having a long life call back fast, precise control of the flash time, continues to form a square wave output power within the flash momentarily (power density) greatly increase the light output power characteristics camera exposure period. By adjusting the length capable of emitting a flash camera exposure time to achieve the perfect combination, greatly reduce the impact on the human eye and minimize environmental interference light for taking pictures. To meet in a variety of lighting conditions, the auxiliary imaging system to achieve the clearest vehicle and driver's pictures. Their use of the unique control technology, the effect of product performance, ease of installation, and the prices are better than ordinary life flash, it is currently on the market, supporting commonly used electronic police flash the best alternative is the preferred electronic police upgrade flash.
5, Studio Flash, for studio, studio, studio and other professional high-power flash photography places, due to the weight and volume and other factors generally can not handheld, often set up in the special tripod or slide.

The concept of rotating beacon lights

Led rotating beacon light after sending or receiving data monitoring center instruction automatically enter power-saving sleep state, in power-saving sleep state monitoring terminal operating current less than 20MA, while ready to receive inquiries, remote settings and command control center immediately wake up.
Detection circuit in the power-saving sleep state has been in working condition, displacement drift, impact, can immediately wake beacon lights when abnormal or parameters overrun monitoring terminal host to the monitoring center sends alarm information.
traffic signal baton applicable to road traffic, population concentration, as the traffic directing evacuation use, the structure consists of injection-molded ABS handle switch, PCB circuit, LED light-emitting diode and PC polycarbonate tubes, compact structure, reasonable arrangement, night 1000 m outside can see lighting instructions.

What is a flash

barricade flashing light is able to send out a strong light in a very short period of time, is photosensitive photographic accessories. More in dim lighting situations moment, but also for the light brighter occasion was subject to partial fill light. Compact, safe, easy to carry, stable performance.
The flash can be roughly divided into three categories,traffic wand flashlight depending on their type, its function and performance are also different.
1, built-in flash, built-in flash will cause a lot of electricity consumed camera, and built-in flash does not support the flash of a variety of advanced features.
2, external flash, external flash is typically located at the top of the camera body, some high-end external flash also offers a variety of advanced features.
3, handle flash, handle flash commonly used in the studio, studio, wedding photography studio and other professional venues. Flash: is able to send out a strong light in a very short period of time, is photosensitive photographic accessories. More in dim lighting situations moment, but also for the light brighter occasion was subject to partial fill light. Compact, safe, easy to carry, stable performance.

The role of road traffic signs

Road traffic signs with graphic symbols, colors and text to pass specific information to traffic participants to manage traffic to ensure the safety of the facilities.
The optical pattern classification mainly include: LED active light style, interior lighting type,car beacon lights retroreflective type. Since the retroreflective type of traffic signs as well as the high beam does not depend on all-day identifying traffic participants, LED active light style has been gradually replace retroreflective type.
One reflects the effectiveness of road safety laws, with concise text symbols clear traffic behavior.
Second, adjusting the traffic flow, efficient flow of traffic, improve road capacity.
Third is to reduce the incidence of traffic accidents to ensure the smooth flow of traffic safety;
Fourth, to save energy, reduce pollution and beautify the road capacity.
