We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.

It is forbidden to use wood flooring or laying wool, linen, chemical fiber carpets and ordinary floor leather.
2, grounding: a, anti-static system must have an independent and reliable grounding device, grounding resistance should generally be less than 10Ω, buried and testing methods should meet the requirements of GBJ97. b. The anti-static ground wire must not be connected to the power supply neutral line and must not be shared with the lightning protection ground wire. c. When using three-phase five-wire power supply, the ground wire can be used as an antistatic ground wire (but the neutral wire and ground wire must not be mixed). d. The cross-sectional area of ​​the grounded main line should not be less than 100mm2; the cross-sectional area of ​​the branch line should not be less than 6mm2; the ground wire of the equipment and the workbench should use multiple strands of plastic conductors with a cross-sectional area of ​​not less than 1.25mm2. The grounding wire should be yellow-green. It is appropriate. e. Brazing should be used for the connection of grounding mains. f. The connection terminals of the anti-static equipment should ensure reliable contact and easy assembly and disassembly, allowing the use of various clip-on connectors such as squid clips and plug holders. g. The grounding system monitoring and alarming device should be installed in workplaces with high requirements on grounding resistance. For example, the SL-038A grounding system monitoring and alarming device produced by our company can monitor the contact between the grounding line and the ground at any time.
3. Ceiling material: Antistatic type should be used. In general, gypsum board products are allowed, and ordinary plastic products are prohibited.
4. Wall fabrics: Anti-static wallpaper should be used. Under normal circumstances, it is allowed to use plaster or lime paint walls. It is forbidden to use ordinary wallpapers and plastic wallpapers.
5, humidity control: a, anti-static work area, the relative humidity of not less than 50% is appropriate. b. It is allowed to use the humidifying equipment to spray preparations or water under the premise of not causing harmful effects on the products to increase the environmental humidity. c. The humidity in the computer room shall comply with the relevant provisions in GB2887, and a similar room shall also comply with this requirement.
6. Regional boundaries The anti-static work area shall be marked with regional boundaries, and warning signs shall be hung in obvious places. The warning signs shall comply with GJB1649, and ionized air bathing equipment shall be installed at the entrance of the work area.
7. Static power: It is forbidden to use and contact static-friendly products in the anti-static work area. Such as the table surface paint or impregnated surface, ordinary plastic veneer, ordinary vinyl and resin surface floor, plastic and ordinary floor leather, polished and waxed wood floor. Ordinary vinyl overalls, caps, shoes, common polyester, synthetic fibers and nylon fabrics, plastics and general rubber shoes operating tools and equipment, ordinary plastic boxes, shelves, bottles, trays and paper products, ordinary foam and general mobile tools, Compressors, injection equipment, evaporation equipment, etc.
II. Application and management of antistatic products at the production site
1. Grounding Grounding is to connect some antistatic products or other equipment to a ground wire. The "independent" ground line is established by the method of buried ground. The resistance between the ground and the earth is <10 Ω. The function is to discharge the charge that may accumulate on the conductor. The static electricity (such as the human body) that accumulates on the conductor is usually guided away by grounding.
Grounding is implemented by the following methods:
1 The human body is grounded through the wrist strap.
2 The human body is grounded through anti-static shoes (or shoelaces) and anti-static floor.
3 Workbench grounding.
4 test equipment, tool holders, soldering iron grounding.
5 anti-static floor, grounding mats.
6 anti-static transfer vehicles, boxes, shelves as much as possible grounded.
7 Anti-static chair grounding.
2, anti-static safety workbench: 1 from the table, anti-static desk mat, wrist strap connector and ground wire and other components. When necessary, static electricity equipment such as ion blowers produced by our company should also be equipped. 2 There should be more than two wrist strap connectors on the anti-static table mat, one for the operator and one for the technicians and inspectors. 3 Anti-static safety workbench It is not allowed to stack plastic boxes, rubber, cardboard, glass and other static-prone materials. The drawing materials should be placed in anti-static paper bags.
3. Static Elimination Equipment: An ion blower should be placed on the product assembly worktable that is prone to generate static electricity. Blowing off the product with an ion blower can quickly eliminate the static electricity generated at any time.
4, anti-static wrist strap: direct contact with electrostatic sensitive devices, personnel must bring anti-static wrist strap, wrist strap and human skin should have good contact, wrist strap system resistance to the ground should be in the range of 750KΩ-10.5MΩ. Anti-static wrist straps should often be detected with a wrist strap tester for damage. Can use our wrist band tester. It is best to use a wrist strap on-line monitor because of the conditions or requirements of the company, because the online monitor is used to connect the wrist strap to the ground. So it can detect whether the anti-static wristband is damaged or the worker wears it at any time.
5, anti-static clothing: personnel into the anti-static work area and personnel exposed to electrostatic sensitive devices must wear anti-static overalls, especially in the relative humidity of less than 50% of the dry environment (such as winter). Overalls fabrics should meet the relevant national standards .
6. Anti-static shoes: Persons entering the anti-static work area should wear anti-static shoes. Persons wearing ordinary shoes should use conductive shoes, anti-static shoe covers or heel straps. Anti-static shoes often use a human body tester to detect its anti-static properties. The SL-033 human body tester manufactured by our company can be used.
7, anti-static socks: Many companies do not attach importance to anti-static socks, in fact, this is wrong. When wearing anti-static shoes, it is best to wear anti-static socks, such as anti-static socks can also wear cotton, but should not wear nylon, because of the poor conductivity of nylon, will prevent static electricity to guide anti-static shoes, sometimes with the human body synthesis When the tester measured a pair of qualified anti-static shoes, the resistance was found to be too high because of the reason of wearing nylon.
8. Anti-static containers: The parts and components of the production site, such as bags, turnover boxes, PCB racks, etc., should be electrostatically shielded. Metals and common containers are not allowed. If necessary, the containers used to store the parts should be grounded.
9. The conveyor belt and drive shaft used in the production line should be equipped with anti-static grounded brushes and struts. Static elimination equipment can be used on the surface of the conveyor belt, such as the ion fan and ion wind bar produced by our company.
10. The assembly fixtures, test fixtures, welding tools, and various instruments used in production sites should be provided with a good grounding wire.
11. Human body comprehensive tester: The human body comprehensive tester shall be installed at the entrance of the production place. Every person who enters the production site shall conduct anti-static test and enter the site after being qualified. Such as my company's human body tester. It can detect the total resistance of anti-static shoes, wrist band and human body.
How to prevent static electricity in industrial production?
The harm of static electricity is obvious to all, and now more and more manufacturers have begun to implement various levels of anti-static measures and projects. However, we must realize that perfect and effective anti-static engineering must be developed in accordance with the actual conditions of different companies and different operating targets. Anti-static measures should be systematic and comprehensive. Otherwise, they may be less effective and even cause destructive reactions. Here we talk about the workshop's specific anti-static method.
