Current Status and Development Trend of American LED Tubes and Linear Lamps

Linear lamps are mainly divided into traditional linear lamps and LED linear lamps. Traditional linear lamps are mainly used for grille lamps, panel lamps and hanging lamps of traditional straight tube fluorescent lamps (such as T5, T8 and T12); LED linear lamps refer to LED integration. The luminaire also includes linear luminaires that use LEDs to replace the light source. Linear lamps are mainly divided into traditional linear lamps and LED linear lamps.

The luminaire also includes linear luminaires that use LEDs to replace the light source. For a long time, the US linear lighting market is dominated by lamps with straight tube fluorescent lamps as the light source. However, after the appearance of LEDs, this pattern has undergone new changes. For example, in 2001, T12 fluorescent lamps accounted for 72% of the total commercial use of linear lamps, accounting for 67% of the total consumption of linear lamps. In 2015, the T12 fluorescent lamps accounted for only the total amount of linear lamps in the commercial field. 7%, the industrial sector only accounts for 12%. According to the prediction of the US Department of Energy, the T12 fluorescent lamps in 2035 account for only 1% of the total occupancy of all linear lamps, while the proportion of LED replacement lamps will increase to 16%. The proportion of LED integrated lamps will be increased. Increased to 61%.

 Agricultural machinery parts investment casting is one branch of Alloy Steel Precision Casting, which is widely used in agricultural machinery markets. Casting of agricultural machinery parts adopts lost wax casting, also called investment casting. 

 In wax pattern process,we mix stearic acid and paraffin wax. In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics.

 In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at  24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.

 In dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing technics,but we using the advanced steam dewaxing technics,which we are very proud of.This can effectively avoid the air-hole and sand-hole,making the casting look much nicer.

 In smelt process,we use middle frequency furnace,avoiding the emergence of the oxide; in molten steel control part,we use Germany-imported direct reading spectrometer machine,assuring its quality before the molten steel out of the furnace.During this process we use ERP production and management software to get the feedback information.

 In heat treatment process,we use electric furnace,and adopt double-temperature control in order to heat the products equally.As a result, the products will have great metallurgical structure.

 Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.

 In machining process,we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.

 Our Agricultural Machinery Parts casting has quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The investment cast of  agricultural machinery parts can be made completely based on your specifications such as drawing, design, sample etc.
