Lenka | the light that gathers

Lenka 
With its poetic and sculptural qualities, the 'Lenka' lighting fixture provides a versatile lighting element that becomes the main actor of the space as a gathering place. Through human interaction, easy modification is ensured, providing radically different sculptural forms and ethereal lighting effects. The independence of the mentioned light sources and the dominant diffusers and shades is the result of ambient quality or focused light.

'Lenka' lighting fixture is a state changer that was created to be consistent with the family home, its significance, and heritage, which rests on the preservation and shaping of the central part of the home - light.
The lighting fixture is designed in such a way that the circle element and all the shapes that directly derive from it become the main shapers of the overall geometry of the product. In this way, they invite reading and symbolize gatherings and togetherness. Also, it allows light to be brought into the very center and increases our perception of its significance.
It consists of fixed metal parts of the rosette, holder and hoop, as well as mobile ones, reflectors and shades, through which favorable light ergonomics are ensured.
details  01
The elements of the lighting fixture can physically change and adjust for the purpose of high-efficiency light but also direct interaction with the user. This results in numerous variations in the geometry of the lighting fixture, and diffuse shades help in this, which in turn affects the laws of scattering and reflection of light, which additionally affect the space itself and the overall experience.
VER 01 /  enables the change through two-part fastener elements. They are attached to each other through the perforation on the acrylic shade and are placed on the ring of the holder of the lighting fixture.
VER 01 /  provides the shades with a minimal point of contact with the fixed part of the lighting fixture, enabling rotation and regulation of light in addition to changing the geometry of the shades and the lighting fixture itself.

VER 02 / the perforation in the shade contains a rubber 'stopper' that stops at the desired location by the force of friction, enabling more extreme and flexible positions of the light shader.
details  03
The shape of the reflector in the shape of a roller suggests two light sources placed in opposite directions for simultaneous direct and indirect lighting. The sockets for LED light sources are connected in a unique element that connects the reflector with the rest of the lighting fixture. Through this joint, the rotation of the reflector is also enabled, and its cooling is achieved through partial perforation of the outer shell of the reflector.
