How Are LED Chips Made?
LED chip manufacturing is mainly to manufacture effective and reliable low-ohmic contact electrodes, and can meet the relatively small voltage drop between contactable materials and provide pressure pads for bonding wires.
What is BUG rating and How to Calculate a BUG Rating
BUG is simply an acronym coined by the Illuminating Engineering Society (IES) and the International Dark Sky Association to better explain how light trespass can be measured. The BUG rating of a luminaire determines how much light trespass that a light fixture produces. The BUG rating replaced the old measuring system known as the “cutoff system” around 2005 and is more comprehensive, taking Backlight, Uplight, and Glare into account (the B, U, and G, of BUG).
IESNA Outdoor Lighting Distribution Types
Lighting distribution: it’s a key factor that is frequently overlooked when we are choosing the proper LED luminaires (especially for outdoors). In the industry lighting, we think about the wattage, efficacy, and colour temperature, but usually forget to consider the way light is distributed from the luminaires. Will the chosen luminaires adequately cover the area we are trying to illuminate based on the position it will be installed? This is where understanding IESNA Distribution Types will help us make a good choice.
What is the Difference Between LM-79, LM-80 and TM-21
From the customer survey report, many customers are easy to confuse LM80, LM79, and L70 or assume they test the same measure in an LED product. Although all of them are used when discussing LEDs, they are not related measurements.
How many high bay lights do you need for industrial lighting
The factors affecting the number of highbay lights in industrial lighting rooms are: 1. Locations. Common applications for highbay lights include warehouses, workshops, exhibition halls, etc. Different application requires different brightness. 2. Lamp Power and luminous flux of highbay lights 3. Space utilization coefficient and maintenance coefficient
