Claims

1. A light-emitting component (10) comprising a carrier (1), a reflective layer (6) and a light source (2), wherein

- the light source is mechanically fixed on a mounting

surface (11M) of the carrier,

- the carrier has an electrically isolating basic body (5) comprising an edge region (50), said edge region bounding the mounting surface,

- the edge region comprises a recess (52), wherein the

reflective layer covers a base surface (53) of the recess, and

- the mounting surface is vertically elevated with respect to the base surface of the recess at least in places, such that the reflective layer is kept away from the mounting surface .

2. The component according to claim 1,

wherein the edge region (50) comprises a spacer (51) as part of the basic body (5) , said spacer being arranged laterally between the mounting surface (11M) and the recess (52) .

3. The component according to claim 2,

wherein

- the spacer (51) and the recess (52) adjoin each other,

- the base surface (53) of the recess extends along a

vertical direction as far as a laterally extending surface (51S) of the spacer, and

- in a top view onto the carrier (1), the laterally

extending surface of the spacer and the base surface are free of overlaps.

4. The component according to claim 2,

wherein

- the spacer (51) and the recess (52) adjoin each other,

- the base surface (53) of the recess extends along a

vertical direction as far as a laterally extending surface (51S) of the spacer, and

- in a top view onto the carrier (1), the laterally

extending surface of the spacer and the base surface (53) of the recess overlap each other in places.

5. The component according to claim 2,

wherein

- the base surface (53) comprises a vertically extending

section (53V) and a laterally extending section (53L) ,

- the vertically extending section stretches along a

vertical direction from the laterally extending section as far as a laterally extending surface (51S) of the spacer

(51) , and

- the vertically extending section is convexly or concavely curved .

6. The component according to one of claims 2 to 5,

wherein

- the spacer (51) and the recess (52) form a step, and

- a laterally extending surface (51S) of the spacer and the mounting surface (11M) are flush with each other.

7. The component according to one of claims 2 to 6,

wherein the spacer (51) has an average lateral width (W) of at least 20 ym.

8. The component according to one of claims 2 to 7, wherein in a top view onto the carrier (1), the recess (52) extends from the spacer (51) along at least one lateral direction as far as a side surface (13) of the carrier (1) and at least 60 % of the electrically isolating basic body (5) are covered by the reflective layer (6) filling the recess at least

partially .

9. The component according to one of the preceding claims, wherein

- the reflective layer (6) is electrically isolating and

comprises a matrix material having white particles

embedded therein, and

- the proportion of white particles within the matrix

material is chosen such that the reflective layer has a reflectivity of greater than 90 %.

10. The component according to the preceding claim,

wherein the white particles are Ti02-particles and the matrix material is made of silicone.

11. The component according to one of the preceding claims, wherein the electrically isolating basic body (5) is an epoxy resin mold compound.

12. The component according to one of the preceding claims, wherein

- the carrier (1) comprises a first lead frame (3) and a

second lead frame (4), wherein the basic body (5) is formed as one piece and surrounds the first lead frame as well as the second lead frame in lateral directions,

- the first lead frame and the second lead frame extend

throughout the basic body and are electrically contactable on a rear side (12) of the carrier, and

- the mounting surface (11M) is remote from the rear side and is formed in places by a surface (31) of the first lead frame and/or by a surface (41) of the second lead frame .

13. The component according to the preceding claim,

wherein the basic body (5) , the first lead frame (3) and the second lead frame (4) close flush with one another at least in places at the mounting surface (11M) .

14. The component according to one of the preceding claims, wherein the mounting surface (11M) accounts for between 30 % and 60 % of a total surface of the carrier (1) .

15. The component according to one of the preceding claims, wherein the electrically isolating basic body (5) and the reflective layer (6) close flush with one another laterally.

16. The component according to one of preceding claims, comprising a radiation-transmissive encapsulation layer (9) which covers the carrier (1), the reflective layer (6) and the light source (2) completely, wherein

- the encapsulation layer is made of silicone,

- the reflective layer comprises silicone and white

particles dispersed therein, and

- the encapsulation layer adjoins the reflective layer.

17. A method for producing the light-emitting component (10) according to one of preceding claims, comprising:

- fixing the light source (2) on the mounting surface (11M) of the carrier (1); and

- applying the reflective layer (6) onto the edge region

(50) of the electrically isolating basic body (5) after electrically contacting the light source (2) in such a way that the reflective layer does not cover the mounting surface and/or the light source.

18. A method for producing a plurality of light-emitting components (10) according one of claims 1 to 16, comprising: - forming a plurality of recesses (52) on the basic body (5) of a common carrier (1C), such that the recesses surround a plurality of mounting surfaces (11) on the common carrier ;
