Embodiment Construction

[0054] Elements that are the same, of the same kind or have the same function are provided with the same reference signs in the drawings. The drawings and the size ratios of the elements shown in the drawings to each other cannot be shown to be to scale. On the contrary, for better description and for better understanding, various elements can be shown exaggerated.

[0055] figure 1 The optoelectronic device 1 is shown. The semiconductor chip 3 is applied on the carrier 2. The electrical contact is achieved via the contact 4 and the bonding wire 5. The semiconductor chip 3 emits primary radiation 6. The semiconductor chip 3 is at least partially surrounded by an at least partially transparent medium 7 having a height 8 above the carrier 2 and a width 9 (aspect ratio) along the carrier 2. The particles 10, 11 that interact with the primary radiation 6 are introduced into the medium 7. Medium 7 has an aspect ratio greater than one. The particles 10, 11 are uniformly distribut...

Abstract

An optoelectronic component (1) has a carrier (2) and at least one semiconductor chip (3). The semiconductor chip ( 3 ) is arranged on the carrier ( 2 ) and is designed to emit primary radiation ( 6 ). The semiconductor chip (3) at least partially surrounds an at least partially transparent medium (7), which has a height (8) above the carrier (2) and a width (9) along the carrier (2). Particles ( 10 , 11 ) are introduced into the medium ( 7 ), said particles interacting with the primary radiation ( 6 ). The ratio of height (8) to width (9) of the medium (7) is greater than one.

Description

Technical field [0001] The invention relates to an optoelectronic device having a semiconductor chip for emitting electromagnetic radiation, and a light emitting device having at least one such optoelectronic device. In addition, a method for manufacturing optoelectronic devices is proposed. Background technique [0002] Known from the prior art are optoelectronic devices and light-emitting devices having the optoelectronic devices. Therefore, the document WO2009 / 135620A1 discloses a light emitting device with a light emitting mechanism that emits electromagnetic radiation. An extension of the lighting mechanism can be an optoelectronic device. The electromagnetic radiation is partially deflected by the interaction with the particles, and the electromagnetic radiation is partially changed in relation to its wavelength. The deflection of electromagnetic radiation can be achieved by the gradient of particle density. However, the adjustment of the particle density gradient is ex...
