Why Merrytek

80% of R&D staffs have technical background and main engineers have over 20 years’ experiences in lighting control products design. Merrytek has been continuing our focus on intelligent lighting control product development, ensuring our customers have the best choice of products and more competitive in lighting market.

Core Technologies Advantages

1 Microwave Motion Detecting Technology

Based on principle of Doppler effect and 5.8GHz microwave detection technology for motion detecting. Currently, merrytek developed a series of motion sensors which support long detection area up to 20m, 15m mounting height and outdoor use motion sensors. Those are at the leading position in our industry.

Typical products:

20m detection range: MC601S, MC601V, MC049V & MC046S.

15m mounting height: MC031V

Outdoor motion sensor (anti-background noise): MC042S & MC042P

2 Slight Motion Detecting Technology

As only support big range movement detecting, microwave is normally used in the places people only make a brief stay, for example, corridor, stair well, warehouse and parking lot. Merrytek use high sensitive microwave module and unique programming, microwave sensors are able to detect very slight movements, i.e. typing, and can be used in office, kitchen and rest room.

Typical products: MC025S, MC034S

3 Integrating of Motion Sensor, LED Driver and RF Module

As the pioneer of integrating technology of sensors and LED drivers, we pride that our sensor drivers has saved system cost of luminaries and led the development of intelligent lighting control.

Typical products: MLC10C-P, MLC16C-P, MLC28C-P, MLC12C-PD & MLC18C-PRF

4 Identifying of Artificial LED Light and Natural Light

As always, Merrytek concentrate on simple intelligent light solution and luminaries structure. We successfully finish the study of patented self-adaptive LED drivers which can identify artificial light and natural light, and supply the cost-effective daylight harvesting solution for office use.

Typical products: MLC40C-PA, MLC40C-PA1

5 Flicker-free LED Dimming Technology

Replacing traditional incandescent and fluorescent lights with more efficient and longer-lasting LED-based solid-state lighting (SSL) is an undeniable trend in the lighting industry. However, since SSL fixtures are directly connected to the AC line, like with legacy lighting, there is a risk that 100-Hz or 120-Hz flicker could occur as a result of driving current ripple at the supply's output. Flicker can make people uncomfortable, causing headaches and other maladies even though the human eye may not detect the flicker.

Currently, most of dimamble LED drivers are difficult to improve flickering as the PWM dimming mode, especially when dim below 30% dimming level. Merrytek newly-developed flcker-free dimming technology can eliminate nearly all flickering and even dim to 2%.

Typical products: ML10C-PV, ML25C-PV & ML50C-PV2.

In the past years, merrytek has been designed a series of patent and unique products, including mounting height 15m high bay sensor MC031V, slight motion detection sensor MC034S, daylight harvesting LED driver MLC40C-PA and so on. Please read more in following pages.
