The invention relates to a lighting apparatus, having a quadrangular lighting surface, wherein the quadrangular lighting surface has a first lateral edge a and an opposing lateral edge a, wherein the quadrangular lighting surface has a second lateral edge b and an opposing lateral edge b, wherein the quadrangular lighting surface is constructed modularly from at least a first lighting module and further lighting modules. The at least first lighting module is triangular, wherein the base surface of the first lighting module has a lateral edge band a vertex Eopposing this lateral edge b, wherein a connecting path between the vertex Eand an intersection point Lof a normal line with the lateral edge bis a height hof the first lighting module, where 0&#x3c;h&#x2266;a and b=b

Lighting apparatus

A light-emitting diode array is disclosed which has two light-emitting diodes which are connected in antiparallel with one another, and a power supply which is suitable for energizing the light-emitting diodes independently of one another in the forward direction. In addition, an optical recording apparatus and a method for the pulsed operation of a light-emitting diode are disclosed.

Light-emitting diode arrangement, optical recording device and method for the pulsed operation of at least one light-emitting diode

The luminous area of a lighting apparatuswith a rectangular luminous area is made up in modular fashion from individual rectangular luminous modules. The basic set comprises a first luminous moduleof a first size, a second luminous moduleof a second size, a third luminous module, whose length corresponds to the length of the first luminous moduleand whose width corresponds to the width of the second luminous module, and a fourth luminous module, whose length corresponds to the width of the first luminous moduleand whose width corresponds to the length of the second luminous module. By combining the luminous modules it is possible to produce backlighting for a multiplicity of display sizes.
