Why COB LED?

LED (Light-Emitting-Diode) is new technology with advantage of saving energy and very long lifespan. But all kinds of LED light sources can not be faultless especially SMD (Surface-Mounted-Device), HIP (High-Power), DIP (Double In-line Package) LED etc. except COB (Chip-On-Board) LED. COB is short for Chip-On-Board, which is a new technology of LED packaging for LED […]

How Does Ambient Temperature Affect LED Efficiency?

LED fixtures must be designed with junction temperature thermal management as a key component and use the correct LEDs. These products will then be robust enough to operate in most ambient temperature applications. Unlike fluorescent sources, cold temperatures do not impact the performance of LEDs.

What Is Junction Temperature?

Junction temperature is the temperature at the point where an individual diode connects to its base. Maintaining a low junction temperature increases output and slows LED lumen depreciation. Junction temperature is a key metric for evaluating an LED product’s quality and ability to deliver long life. The three things affecting junction temperature are: drive current, […]

What Is Lux?

Lux is lumen per square meter. According to Wikipedia, “The difference between the lux and the lumen is that the lux takes into account the area over which the luminous flux is spread. 1000 lumens, concentrated into an area of one square meter, lights up that square meter with an illuminance of 1000 lux. The […]

Why Is the Lifespan of an LED Measured as Lumen Depreciation?

The life span of an LED is vastly longer than that of incandescent, fluorescent or HID lamp sources, generally lasting 50,000 hours or longer. Although the LED never really burns out, product life span is measured by lumen depreciation. The Illuminating Engineering Society’s (IES) current standard for calculating the life of an LED as the […]

Why LED?

The introduction of LED light sources has brought several benefits compared to that of traditional lamps. These new sources have characteristics of high efficiency and duration, allowing savings in terms of maintenance, replacement lamps and energy consumption. LEDs can have multiple sizes, wattages and shapes to suit the most complex design and decorative requirements. The […]

How Do I Compare My Current Lighting with LED Lighting?

In the past, we have generally referred to the brightness of a bulb in terms of its wattage, or the amount of power that the bulb uses (or energy it consumes). Because of the disparity between incandescent and LED technologies, we have to change our language a bit in order to account for progress. When […]
