When starting medical machining, the operator should adjust the feed speed to a very small value, execute in a single block, concentrate on positioning, dropping the tool, and inserting the tool quickly. Put the hand on the stop button and stop immediately if there is a problem, pay attention to the direction of the tool movement. To ensure safe feed, then slowly increase the feed speed to a suitable level, and at the same time add coolant or cold air to the tool and the workpiece. Read more

With the rapid development of the industrial revolution, the consumption of resources is also increasing, and many resources are non-renewable. In order to ensure the normal development of the future, people began to study energy-saving products. LED high bay light is one of them. The main function of LED heatsink housing high bay light is the lighting of large-scale occasions or the lighting of industrial and mining industries. It is a widely used lamp. However, when applying LED high bay lights, four technical indicators need to be paid attention to:

  • 1. Thermal resistance directly affects the heat dissipation of LED high bay lights. The lower the thermal resistance, the better the heat dissipation; the higher the thermal resistance, the poorer the heat dissipation, so that the temperature of the device increases, which will affect the wavelength shift of light. According to experience, when the temperature rises by one degree, the light wavelength must drift 0.2~0.3nm, which will directly affect the light-emitting quality of the device. Excessive temperature rise also directly affects the service life of LED high bay lights.
    2. Color rendering is an important indicator of LED heatsink housing high bay lights, and the color rendering must be above 80.
    3. Whether the color temperature distribution is uniform or not will directly affect the lighting effect; and the color temperature and the color rendering index are related to each other, and the change of the color temperature will cause the change of the color rendering index.
    4. Mastering the light intensity distribution diagram of LED high bay lights is necessary for the correct use of LED high bay lights. Manufacturers must provide customers with various parameter indicators of LED high bay lights.

PTJ specializes in the R&D, manufacturing, sales and service of LED street lights, LED high bay lights, LED tunnel lights, high-efficiency LED modules and other products, providing high-quality and high-performance LED heatsink housing application products for professional channel customers and end customers at home and abroad And solutions. The current products are mainly LED energy-saving lighting, including venue lighting, municipal lighting, port lighting and other series of products.

With the rapid economic development, various industrial plants have sprung up like bamboo shoots, and these industrial plants have different locations in the space and environment, and the lighting methods used in the workshop are very different, but most of the industrial plants today Regardless of the location of the space, the most common lighting method they choose is LED heat sink bar factory lighting. What are the advantages of such a lighting method? Industrial enterprises like it so much.

Industrial and mining lamps refer to the general term of lamps used in factories, mines, warehouses, and high-bay production areas. In addition to various lighting lamps used in normal environments, there are explosion-proof lamps and anti-corrosion lamps used in special environments. light. The led industrial and mining lamps have high luminous efficiency and are more energy-saving. It is equivalent to a 100W LED industrial and mining lamp that can replace the traditional 250W traditional industrial and mining lamp. Traditional light sources have the disadvantage of high temperature of lamps, and the temperature of lamps can reach about 200-300 degrees. The LED itself is a cold light source, the temperature of the lamp is lower, and it is safer, and it is cold-driven. LED industrial and mining lamps are now in continuous innovation. The new type of led industrial and mining lamps have a more reasonable radiator design, which greatly reduces the weight of led industrial and mining lamps, and reduces the overall weight of about 80W led industrial and mining lamps to below about 4KG. It can solve the heat dissipation problem of 80-300W LED heat sink bar high bay lights.

What are the requirements for the use of high bay lights?
In order to meet the visual needs of different production operations and the needs of lighting installation conditions, the reflector of the industrial and mining lamp should be able to produce various widths of light distribution. The surface is painted and glazed to make it appear white, and reflectors made of aluminum, glass mirrors, prism glass and other materials can obtain a wide light distribution, which is suitable for large-area, vertical or nearly vertical workplaces . For tall workshops and places with tall machine tools that require separate lighting, reflectors made of materials with strong light control properties such as prism glass, mirror glass and polished aluminum can be used to obtain a narrow beam distribution.

In order to work reliably for a long time in places with poor environmental conditions such as dust and humidity, high bay lights have special requirements in terms of structural design, housing and reflectors. Closed luminaires or convection luminaires with upward luminous flux should be used in dusty environments; attention should be paid to the airtightness of the enclosure and the surface treatment of the reflector in humid environments; open luminaires are commonly used indoors, using enamel surface reflectors and surface oxidation Aluminum reflector with thick aluminum film or coated with silicon dioxide protective film; considering the inevitable vibration in the production site, the fixed light source should adopt anti-loosening lamp holder, etc. There are many ways to fix high bay lights. General lighting has the form of ceiling, embedded, hoisting (using straight pipe or chain) and suction wall. Movable local illuminators are equipped with corresponding hooks, handles, clamp feet, etc.; fixed local illuminators are generally firmly locked on the working machine with screws or fixing mechanisms.

First, most of the PTJ LED high bay lights use imported SMD lamp beads as the main light source, and use imported semiconductor crystals. It has the advantages of high thermal conductivity, low light attenuation, and no ghosting.
Second, this kind of lighting uses no polluting materials such as lead and mercury, so it has the advantage of being green and environmentally friendly without any pollution.
Third, it adopts a very unique heat dissipation design, and is cleverly combined with the electrical box to effectively spread the heat, thereby reducing the temperature in the LED heat sink bar lamp, which effectively ensures the life of the lamp body.
Fourth, it also has very good color rendering properties. The color of any physical substance is very true. There are many light colors to choose from. No matter what the environment is, it can be satisfied, which eliminates the past. The lighting brings the depressive emotions to the staff, thereby increasing the effective work rate of people.
