Led Panel Light-to-date safety regulations

The current market a wide range of energy-saving lamps, and more technologically advanced and more environmentally friendly to count Led Panel Light. Data show, Led Panel Light 80% power than incandescent, fluorescent energy saving lamps energy saving than 50%. Led Panel Light has energy saving, environmental protection advantages in the lighting industry has become a major trend. Led Panel Light can be a distinct advantage embodies the following aspects:
1. Low-voltage power supply, low power consumption: In general, Led Panel Light working voltage is from 2 to 3.6V, operating current is 0.02 to 0.03A. That is to say: it does not exceed power consumption of 0.1W;

2. Small size: Led Panel Light is basically a very small chip which is encapsulated in epoxy resin;

3. Long life: at the right current and voltage, up to 10 million hours of their life, almost no maintenance. Also, Led Panel Light with full epoxy encapsulated, than light bulbs and fluorescent tubes are strong, light body and no loose parts, easy to damage;

4. High brightness, low-calorie: ordinary incandescent and halogen lighting, although cheap, but the light efficiency is low, due to the thermal effect of light and vain power; Led Panel Light for lighting lamps, not only the high luminous efficiency, and produce almost no heat cold light source power;

5. Green: Led Panel Light is made by a non-toxic materials, unlike fluorescent lamps containing mercury can cause pollution and can be recycled;

6.Led Panel Light also has no flash, applicability, high stability, short response time and other characteristics;

As LED technology and products used in traditional lamps have very different properties, the existing safety standards in general lighting is obviously not applicable.

Led Panel Light safety norms

Billion Bo Technology Certification Center (EBO) Special write this article to illustrate the current Led Panel Light of safety testing requirements (to UL standards for example).

(A) Led Panel Light, Safety Specifications:

As technology improved, Led Panel Light in the use of simple past few decades has been used in light, lights, etc., and gradually used in mobile phone backlight, interior lighting, brake lights, LCD televisions, laptop computers and other auxiliary backlight lighting; in the last two years, it starts to become the main lighting system can cover the scope of the application, outdoor, commercial, and home and other products are respectively:

Category (lighting) products

Building garden lights, searchlights, step lights, lights, balcony

Outdoor lights, column lights

Commercial lighting, display cabinet lighting

Home ceiling lamps, wall lamps, cabinet lamps, floor lamp, table lamps, etc.

LED light source to enhance manufacturing technology, application-level variable wide commitment to protect the safety of consumers, UL has developed LED module and lighting for safety standards UL8750, to regulate Led Panel Light products, and officially released in 2009. This standard is the industry's sales of LED products to North American safety regulations necessary for the LED light source for the main types of products, including lamps, bulbs, drivers and so on, the next LED illumination products not only have safety regulations, but also to be LED light source and the module for the special attributes for validation.

(B) Led Panel Light in the UL standard classification:

For Led Panel Light, LED bulbs and LED power supply and other basic products of three categories, corresponding to the extended to the finished products or components, the different applications of the corresponding standards and the safety precautions are not related to the same start as the specific :

What is the resistence of a light bulb when cold and why?

why is the resistence like this?? and can you measure the resistence of a light bulb when hot and why??

The resistance cold is much lower than hot. This can be proved by measuring it cold with a ohmmeter then powering it up and measuring it hot by measuring the voltage and current and using ohms law.
