Lighting Symbols and Signs-TJ2 Lighting

An LED driver is an electrical device that regulates and controls the power supply to an LED or a string of LEDs. LEDs require a specific voltage and current to operate efficiently and safely, and LED drivers are responsible for providing the appropriate electrical elements such as current and voltage for the LEDs. It is an important piece to an LED circuit and to operate without one will result in system failure.

Here are some functions of LED Drivers:
Voltage Regulation, Current Regulation, Dimming and Control, Compatibility, Efficiency, and Protection.

An opening or hole in a surface, such as a ceiling or wall, through which a lighting fixture or luminaire is installed. Cutouts are designed to accommodate recessed or surface-mounted lighting fixtures, and they can vary in size and shape depending on the specific requirements of the fixture and the aesthetic preferences of the space.

Cutouts are essential in architectural and interior design because they allow lighting to be integrated seamlessly into a room or building’s structure. The purpose of cutouts is to provide a clean and unobtrusive way to install lighting, minimizing the visual impact of the fixtures themselves and allowing the light to be directed where it’s needed without drawing attention to the fixtures or their housing. This creates a more aesthetically pleasing and unobtrusive lighting design in residential, commercial, and architectural settings.

Class I
equipment in which protection against electric shock does not rely on basic insulation only, but includes an additional safety precaution in that accessible conductive parts are connected to the protective earthing conductor in the fixed wiring of the electrical installation in such a way that accessible parts cannot become live in the event of a failure of the basic insulation.

Class II
equipment in which protection against electric shock does not rely on basic insulation only, but in which additional safety precautions such as double insulation or reinforced insulation are provided, there is no provision for protective earthing or reliance upon installation conditions.

Class III
equipment in which protection against electric shock relies on supply at SELV and in which voltages higher than those of SELV are not generated.

Electric and electronic equipment will deteriorate or malfunction when water or dust accesses the device. The IEC has developed the ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids. The ratings are widely used throughout the industry.

Solid foreign object protection Level: From 0~6
Water Protection Level: From 0~8

UL Certificate, also known as a UL listing, means the products have been tested by Underwriters Laboratories(UL) for fire safety and electrical safety. UL is a global safety science organization known for evaluating and certifying various products to ensure they meet safety and quality standards.

A UL lighting fixture is marked to indicate the product has passed the specific safety requirements necessary to be used by consumers in their homes and in business areas.

Core lighting services of UL
1. Lighting Safety Testing and Certification
2. Lighting Performance
3. Lighting Global Market Access
4. Connected Lighting

The letters ‘CE’ appear on many products traded on the extended Single Market in the European Economic Area (EEA). The CE mark means that the manufacturer is responsible for the compliance and regulations of a product sold in EEA with all applicable European health, safety, performance and environmental requirements.

Having a CE marking on a product offers several benefits when it comes to selling and distributing products within the European Economic Area (EEA):

● businesses: know that products bearing the CE marking can be traded in the EEA without restrictions
● consumers: enjoy the same level of health, safety, and environmental protection throughout the entire EEA
