Thermal conductive silicone piece: its based on silica gel material; add some metal oxide as the auciliary materials. Its medium about heat conduction material by a special technology. Silicone rubber puts organic ilicon resin as the cohere materials. Fill the thermal conductive powder; it is polymer composite that is a target of thermal conductivity. There are some materials: Organic silicon resin (basic material) Insulating thermal conductive filler:Alox、Mgo、CBN、ALN、BeO、quartz and ot...(more)
LED controller control LED lamp switch of each location in circuit by using the chip processing. According to the preset procedure, the controller controls the driving circuit to make the LED array regularly luminescence. Then it can display a text or graphics. LED controller has many advantages, which can prolong the lifetime of LED and save energy. The LED controller also has convenient wiring. Whats more, according to the actual needs of customers, it can realize the change effect of jump and...(more)
There are many kinds of plastic tubing, and we mainly introduce three types: PVC tubing, CPVC tubing and UPVC tubing. (1)PVC tubing According to the hardness and the properties of materials PVC, Polyvinylchloride, (SG1-SG7), and the density are about 1.4g/cm. What is under SG4 is generally called soft product. It needs to add a lot of plasticizers during the molding, and it is mainly used for making artificial leader, wire and cable insulation and sealing elements. Hard product above SG5 has app...(more)
There are many kinds of street lamp power supplies. According to the driving method, the street lamp power supplies can be divided into two categories. (1)Constant current mode Output current of the drive circuit is constant; while the output DC voltage is different in a certain rangeas the size of the load resistance varies-when the load resistance becomes small, the output voltage will be low; when it becomes big, the output voltage will be high. The constant current circuit allows the load to...(more)
LED power driver is a voltage converter, which can make a power supply convert into a specified voltage and current to drive the LED light. According to the rules of using electricity and the performance requirements of LED driver, we need to consider the following points when we select and design the LED power driver. (1)High reliability. LED power driver, especially the driving power of LED street lamp, needs to meet the high reliability because the maintenance is convenient and the maintenanc...(more)
This kind of heat sink is the one of the popular sink heats. It fully consists of pure aluminum. The aluminum takes up the maximum metal quantity in earths crust. It has two characteristics, one is low cost and the other is heat capacity. It can dissipate heat quickly. The effect of heat dissipation can influence its construction and workmanship directly. The polishing of the bottom is better than the thermal slug which has better heat dissipation. The minimum groove of heat sink is only1.1mm if...(more)
Electric suction pen has built-in vacuum pump and it needs no external vacuum system. Electric suction pen can continue working more than 1000hours, which has strong suction, and two branch suction pens can work at the same time. It is produced by electrostatic materials, which can make sensitive elements avoid electrostatic damage. Vacuum suction pen can be divided into pneumatic suction pen and manual suction pen. The source of pneumatic suction pen requires 4-6 kg of compressed air, and the p...(more)
Vacuum suction pen, which looks like a pen, is a small pneumatic tool. It consists of a plastic or a rubber shell, a vacuum generator (pneumatic), a vacuum chuck, an elbow and a reel (pneumatic), and it can be flexibly used for assembly of small parts. Vacuum suction pen can be divided into two categories: pneumatic suction pen and manual suction pen. Air supplyrequirement of pneumatic suction pen is 4 to 6 kg of compressed air. The power of manual suction pen is the rubber bladder. Pneumatic su...(more)
