Freedom for Light, Beauty for the World
LumiFree is an innovative liquid crystal device that allows for the free control of the light distribution characteristics of luminaries. It is a unique, two-axis-independent light distribution control device made possible through JDI's deep liquid crystal expertise. Lighting fixtures incorporating LumiFree bring unprecedented value.
Appropriate time, appropriate place, appropriate light.
LumiFree enables the delivery "the right amount of light at the right place at the right time., in the necessary place". By solving light pollution, it contributes to a sustainable society.
One device can handle multiple scenes
Even in scenes where multiple lighting fixtures were needed, optimal lighting can be achieved with just one device. With LumiFree, one lighting fixture can handle scenes that require various light distributions.
Enhancement of spatial value through light.
It is possible to change the light distribution silently and quickly. By utilizing the unprecedented characteristic of variable light distribution, we create new value in spaces where lighting is used.
The various light distribution shapes such as lines and ellipses created by LumiFree enable lighting fixtures that can freely control the illumination range of light.

LumiFree Operating Principle
In addition to developing a new liquid crystal material, JDI realized an optimum structure for light distribution control by utilizing various technologies originally developed for use in liquid crystal displays.
The light distribution characteristics are changed by electrically controlling the liquid crystal and diffusing the light passing through the LumiFree panel.
Since light distribution cannot be narrowed (squeezed), LumiFree should be used in combination with a light source with a narrow light distribution angle.
