The technology of LED (light emitting diodes) lighting, especially with modern high power LEDs on the horizon, has developed very rapidly over the past few years. LEDs have acquired substantial economical relevance worldwide, thanks to their superior lighting capacity and high level of user acceptance. The market share of LED light sources and LED luminaries is increasingly rapidly at an unprecedented rate. Moreover, LEDs for lighting application are becoming widely adopted due to economic, energy and environmental reasons. With the increasing demand of LED applications, the need for high-power high-brightness LED lights grows gradually.
To design a single higher power LED chip, a large sized LED chip is proposed but there are applications where thousands of lumens are required from a single source. A common solution here is to use a chip-on-board (COB)-style LED. In order to increase the output optical power, a high power COB LED array packaging is universally preferred. In this configuration, an array of small-size high-power LED chips is mounted on a metal-based or ceramic-based board. In the last decade, a ceramic-based platform for high power LEDs swept the industry while replacing the previous lead-frame approach. However, there’s a new tech that’s creating quite a buzz across the growing LED community which is dubbed as “Quantum Boards”. Let’s take a look how the two technologies stack up against each other.
What is Chip-on-Board (COB)?
While the high-power LED packages can handle a few watts of power and thus hundreds of lumens of light output, there are applications which would require thousands of lumens from a single source. This is where a chip-on-board (COB)-style LED comes to the picture. In a multiple chip configuration, several chips are mounted in a housing, while in the COB LED technology, an array of chips is mounted on a common board or substrate. It usually consists of multiple smaller size high-power LED chips encapsulated on the metal-based or ceramic-based board. In modern COB LED configuration, the phosphor-silicone encapsulate mixture is molded on the chip array surface. With COB, the number of LED chips within a package can be up to several thousand pieces with much higher packaging densities that with single chip LED configuration.
What is quantum boards canada?
Quantum boards by Horticulture Lighting Group (HLG) are the highest efficiency, high intensity horticulture light engines. HLG quantum board is a large circuit board with hundreds of mid-power LEDs mounted on it. The large circuit board makes for a more even light distribution. It consists of a number of micro-LEDs which are connected in series to form strings to achieve high voltage operation. quantum board samsung 301b are essentially the same as COBs except they span a much larger area to cover a larger heat sink. It has low power consumption, which can reduce the cost of additional heat sinks. The term eco farm quantum board was first coined by HLG for an LED grow light with the diodes evenly spread out on a board.
Summary
In a Chip-on-board LED configuration, an array of chips is mounted on a common board or substrate. It usually consists of multiple smaller size high-power LED chips encapsulated on the metal-based or ceramic-based board. It has great thermal resistance, larger cooling area and better lighting effects, plus it’s great for DIY projects. best quantum boards are a relatively new technology designed by the folks at the Horticulture Lighting Group and they are essentially the same as COBs except they span a much larger area which makes for a more even light distribution.
