2Luci’s power supply solutions businessWe solve problems
with custom power supplies!
We Luci Co., Ltd., have been accumulating AC/DC and DC/DC technology in LED lighting for over 15 years.

We have started our power supply business by using this technology as customised switching power supplies,

specialising in customer applications. We offer a wide range of services, including power supplies for recharging,national standard PSE compliance based on our safety design, obtaining legal standards in various countries, andproposals with various EMI/EMC compliance and package sizes to meet customer requirements (our own technology
development samples with minor modifications), as well as the creation of wiring harnesses.
We offer proposals that comply with QCDS.

Design philosophy

Three Efficient Articles
All the power supplies we supply are designed according to the ‘Three Efficiency Principles’, whether they are choicely
modified or fully customised. We provide support from design to post-delivery and offer ‘security and stability’.

Efficiency

Contributes to improved production efficiency!
To facilitate the integration of the power supply, we can offer shapes
and terminal block orientations to suit your requirements.

Contributes to energy savings in products!
We can offer power supplies tailored to the load conditions of control
boards, batteries and sensors.

Contributes to a breakaway from general-purpose

Procurement manufacturers’ stock situation & stable production!

a procurement schedule for parts.boards, batteries and sensors.

PSE-compliant
Based on PSE compliance with our safety design at the core, we offer proposals in various EMI/EMC conformity and enclosure
sizes to meet customer requirements and design for compliance with national standards.

Service
Flexible

Cost

You can order products tailored to yourrequirements in terms of capacity, size andvarious standards.

The price is set at a level that makes it easy
for customers to try it out, in response to thecustomer’s comment that “customisation
seems too expensive to develop...”.

Minor

Speed

We can respond from request to deliveryof prototypes in as little as three months.
Proposals from past prototypes are also
possible.

Our unique technology development samples can be “Chooi-Chooi-Changed” (Chooi-Chooi for short)Compared to development from scratch, this reduces the challenges of specification determination,
cost, development speed and delivery time.

We design and develop from scratch what is not available in general-purpose products, whether board,
unit or adaptor type. We design power supplies to suit the product,
without the need to design the product to suit the power supply.

This is the difference!
Luci’s power supply development
In response to customers who say that customisation seems to be too expensive, Luci has set a price that makes it easy for customers to
try it out. We recommend the ‘Minor Change’ option for customers who want to reduce development costs.
