摘要:
The invention relates to a luminescence conversion of LED which uses a blue emitting chip and two illuminating substances, whereby one emits a red and the other a yellow to green. Both illuminating substances are separated upstream from the chip.
摘要:
Disclosed is a luminous substance that belongs to the class of oxinitridosilicates, comprises a cation M which is doped with divalent europium, and is of general formula M(1-c)Si2O2N2:Dc, wherein M = Sr or M = Sr(1-x-y)BayCax with the stipulation x+y
摘要:
Disclosed is an LED comprising inorganic luminous substance. An LED chip emits primary radiation ranging between 300 and 470 nm, said radiation being partly or fully converted into longer-wave radiation by means of at least one luminous substance which is exposed to the primary radiation of the LED. The conversion is achieved at least with the aid of a luminous substance whose average particle size d50 ranges between 1 and 50 nm, preferably between 2 and 25 nm.
摘要:
Disclosed is a surface-mounted component comprising an optoelectronic semiconductor chip (1), a molded member (2) that is molded onto the semiconductor chip (1), an assembly area (3) which is formed at least in some points by a surface of the molded member (2), and at least one terminal point (4a, 4b) which is overlapped laterally by the molded member (2) or extends flush with the molded member (2). Also disclosed is a method for producing such a component.
摘要:
A light source uses a yellow to red emitting phosphor with a host lattice of the nitridosilicate type MxSiyNz:Eu, wherein M is at least one of an alkaline earth metal chosen from the group Ca, Sr, Ba and wherein z = 2/3x + 4/3y.
