A five-point issues and the alternatives on framework and style of LED lights

A five-point problems and the solutions on structure and design of LED lights

 

 

 

The application of LED lights are a lot of attention and favor of the enterprise, but there are some problems in structural design, lighting, creative, design, caused no small confusion to the use and selection of the owners. This paper discusses the LED lamp structure and design of a five-point problem and propose appropriate solutions, the main problems in the current market a single “naked” street are as follows: First, the surface treatment (including power), it is difficult to withstand erosion of long harsh environment.The so-called “naked” street is generally the radiator directly to the exposed street lamp.Some manufacturers believe that this is more conducive to heat, but the premise is that the lamps must be installed in a relatively clean environment, free from the influence of external adverse conditions, the practical application of the lamps are mounted directly on the outdoor, may experience acid rain, dust storms, Blizzard, exposure and other harsh environments. Secondly, due to the small proportion of aluminum alloy, and superior thermal performance, heat sink of the LED lights generally use aluminum alloy, aluminum and chemical properties are very active, easily and acid-base reaction, exposure in the air is also very easy oxidation . Although the corrosion resistance after anodizing can be greatly improved, but the lighting installation still can not guarantee the oxide film is not damaged when the oxide film is damaged, the aluminum alloy active chemical properties can be manifested. Prone to pollution, acid rain, some of the gaps and grooves in the acidic water will accumulate in the lamp body, the volatilization of the storm after the gap or groove in the acidic water can corrode the lamp body, subject to corrosion the lamp body not only affects the appearance, the heat, but also affect the mechanical properties. In addition, the “naked” street lights due to the structural characteristics of the radiator itself causing it is very easy to accumulate dust and snow.The dust cover on the radiator, the cooling performance of the aluminum alloy will be adversely affected, the snow on the surface seem more conducive to heat, but in fact the heat lamp in the cold weather is enough, a lot of snow but it will poles caused by the enormous pressure.
Second, the rectangular shaped design does not meet wind resistance requirements.Rectangular-shaped mentioned here refers to the lamp was nearly square shape, a large area of the plane of each side were tested. This plane feel better power when the wind from a plane perpendicular to blow over, the plane can not be the wind differentiation, and thus create pressure to the fixed structure of poles and lamps. This pressure was not obvious under normal circumstances, but when the lighting poles after a long period of Zhao and corrosion to blame, should along??% B???

A0? Will lead to decline in the middle part of the cooling efficiency. temperature, the formation of the heat island effect. LED heat island? The AF? Around the LED aging faster, higher failure rate.
Fourth, the overall design to bring the post-maintenance difficulties. The overall design refers to the entire light of the lamp chamber is designed with an overall maintenance or light source chamber and power chamber designed to maintain the overall. In recent years, the practice shows that the LED lamps can not achieve maintenance-free. This overall style lamps precisely can not be maintained, the general road failure in the elevated car can not complete the maintenance tasks, to lights replaced back to the factory repair. This way would force manufacturers into the role of both manufacturers and service providers need to pay a heavy price from a manufacturer.
Fifth, the sharp edges and corners of the naked heat lamp safety standards do not meet the requirements. Sharp edges and corners, some metal parts of the lamp body to appear more sharp cusp. This pointed the existence of at least three disadvantages.First, the processing and handling is difficult to protect, easy to curl. Second, the surface treatment difficult, plating or spray, the workpiece itself should be charged at the cusp prone to the phenomenon of poly electricity, or cause there to burn, or cause excessive thickness of coating (coating). Third, easy to hurt the operation of the workers, some manufacturers of light due to the edges and corners too sharp turn with workers often scratch the hand, the more dangerous is that if the workers in the elevated car lights installed scratch may be due to the instinctive reaction Shousong open, the consequences would be disastrous.
For the above five questions, this paper examines some solutions. The first two questions, I believe that a streamlined superstructure can be added to the lighting, streamlined superstructure do not have a large area of the plane, and preferably the middle, peripheral. Of course, have a design on the lid vents and diversion surface. So 4:00 advantages: first, the cover can reduce the exposure of UV damage to the radiator surface protective layer; streamlined shape is not conducive to stay in the accumulation of rainwater in the above, can most of the water directly to the ground to reduce the pHmaterial corrosion lamps; Third, streamline surface can significantly reduce the dust and snow accumulation in the above, allows for heat dissipation to reduce the light poles and fixtures pressure; wind, streamlined surface can differentiate into multiple directions the force, reduce light poles and lamps pressure.
The third, the four questions I recommended that the fixtures will be “piecemeal” and give up the overall design, modular design instead. The fifth issue that the proposed lighting design engineers standing operating workers’ point of view, try to pay attention to the details of the problem in the design.
In addition, in terms of design, the traditional lighting design has accumulated years of experience in the semiconductor lighting design engineers to draw the essence of traditional lighting. Compared with the traditional lighting, LED light source has a small size, flexible array can achieve a variety of beautiful product design. In addition, the semiconductor lighting design engineers should be combined with the geographical and cultural development of industrialization and the artistic taste of the design products. The place has its own unique local culture and customs, only more popular, according to the local characteristics of the design of the lamp can also allow visitors a better understanding of the local specialties. For example, the author a few years ago the idea of creative design “sky sword”, “Zheng Love” and the recent idea of creative design “UFO”, “boxer”, “Gourd Doll” has been favored by many customers and colleagues.
At the same time as the lighting designer, unless proficient in lighting knowledge, should also continue to improve their overall quality of people’s daily lives, know how to find and feel the beauty of life, and emotion into the work design, in order to achieve a viablethinking of lighting design.
The author believes that with the increasing competition in the Chinese market is becoming more international oriented, many SMEs lack the support of the marketing network and brand, should walk the road of professional development, focusing on product quality. The development of enterprises to focus on how to develop high-quality, long life, low price products, in order to create a win-win situation of consumers, businesses and governments.
