Discrete LEDs by Cree LED
Cree LED – the world leader in production of semiconductor components based on silicon carbide (SiC) and gallium nitride (GaN).
VD MAIS supplies about 90% of CREE LED products to the Ukrainian market, provides engineering services and consulting. The status of the special partner is confirmed by the title of CREE Solution Provider
PCBs for LEDs
We supply printed circuit boards for LED applications, created according to customer specifications, and also maintain stock of the most popular standard LED PCBs.
The production of PCBs is carried out in accordance with the requirements of the IPC-A-600H.
Typical PCB specifications:
- thickness of copper – 70 microns
- thickness of aluminum – 1.0 mm
- copper coating – HAL
- protective solder mask – WHITE
- type of the base material – CCAF-01.
Also, VD MAIS produces printed circuit boards of non-standard configurations according to customer requirements.
Mounting LEDs on PCBs
Production of the VD MAIS is adapted for the quick execution of orders for LED appliances. We need no more than 24 hours to produce even a large batch of LED modules.
Soldering of SMD LEDs is performed on a dedicated automated line equipped with Samsung SM321 robot to mount components and SEHO Go Reflow2.3 reflow oven.
To ensure a completely repeatable result, SEHO PowerSelective selective soldering robot is used for the assembly of THD LEDs with a production capacity of up to 8 soldering points per second.
LED-Drivers
VD MAIS supplies LED-driver by MEAN WELL (Taiwan), HELVAR (Finland) and RECOM (Germany). At the initial stage of a project, our specialists help clients to select right LED-drivers that will ensure reliable operation of the finished light fixtures.
The portfolio of the AC/DC converters supplied for LED applications includes models with built-in power factor correctors, with various options of brightness control (dimming), with appropriate degrees of protection – from open-frame models to rigid sealed devices (IP69) in metal enclosures, with high resistance to vibrations, shocks and temperature variations.
The line-card includes specialized devices for use in high-bay luminaires, architectural and landscape lighting systems, budget models for outdoor advertising, solutions for working in conditions of high humidity, etc.
Secondary optics
We supply high-quality secondary optics for LED systems manufactured by LEDil Oy (Finland).
At the requests from our customers we select appropriate lenses for luminaires: symmetrical and asymmetric, borosilicate glass or high-temperature silicone compounds, single or arrays for standard LED-modules with linear or figured arrangement of LEDs or COBs.
