Definitions
- the invention relates to an optoelectronic component according to the preamble of patent claim 1.
- Such components are generally known. Since the luminescence diode chips can send light in different colors, the components can be used for multi-colored ones
- the luminescent diodes are also arranged together in a reflector, the component remains relatively small despite the multicolored nature of the emitted light.
- the light output remains below the sum of the light outputs of the individual luminescence diode chips.
- the object of the invention is to specify a component with improved light output.
- the direct line of sight between the luminescence diode chips is interrupted by diaphragms in the component according to the invention, only a small fraction of the radiation emitted by one luminescence diode chip is absorbed by the other luminescence diode chips. These measures eliminate a major cause of the losses that occur.
- the light output of the component according to the invention is therefore essentially equal to the sum of the light outputs of the individual luminescence diode chips. Further advantageous embodiments of the invention are the subject of the dependent claims.
- FIG. 1 shows a plan view of a component that can be equipped with a large number of luminescence diode chips
- FIG. 2 shows a cross-sectional view along the section line II-II in FIG. 1;
- Figure 3 is a cross-sectional view through a modified embodiment of the component.
- FIG. 1 shows a plan view of a component 1, which is explained in more detail below with reference to Figures 1 and 2.
- the component 1 has a housing 2 in which a recess 3 is formed.
- the depression 3 with its bevelled side walls 4 serves as a reflector for the luminescence diode chips 5 arranged in the depression 3.
- the luminescence diode chips 5 are arranged on a contact carrier 6 (leadframe), the connection elements 7 of which protrude laterally from the housing 2.
- the contact carrier 6 is located in sections under cover layers 8, which serve to fix the contact carrier 6.
- the contact carrier 6 is divided into individual landing sites for the luminescence diode chips 5 and connection areas 10 for the bond wires used for bonding the luminescence diode chips 5.
- the bonding wires used to connect the luminescence diode chips 5 are not shown in FIGS. 1 and 2.
- the luminescence diode chips 5 are typically arranged in the housing 2 at a distance of 0.8 mm, measured in each case from the center of the luminescence diode chips 5. Between the landing sites 9 for the luminescence diode chips 5 there is an approximately 0.2 mm wide gap. In the case of FIGS and the embodiment shown in FIG. 2, the gap in the contact carrier 6 between the landing sites 9 with the intermediate wall 11 with walls that are wedge-shaped in cross section is used. The direct visual contact between the LED chips 5 is interrupted by the intermediate wall 11. Therefore, the radiation emanating from one of the luminescence diode chips 5 cannot be directly absorbed by one of the other luminescence diode chips 5. For this reason, the light output of the component 1 is approximately equal to the sum of the light outputs of the individual luminescence diode chips 5.
- the wedge-shaped cross section of the intermediate wall 11 ensures that the light incident on the intermediate wall 11 is reflected to the outside.
- the height of the intermediate wall 11 should advantageously be up to 25%, preferably up to
- the emission characteristic of the luminescence diode chips 5 is therefore decisive. If the luminescence diode chips 5 mainly emit downwards, the height of the intermediate wall 11 can also be smaller than the height of the luminescence diode chips 5.
- the contact carrier 6 is first extrusion-coated with a thermoplastic or thermoset, and then the luminescence diode chips 5 are deposited on the landing sites 9 and bonded.
- the depression 3 is then filled with a resin which is transparent to the radiation from the luminescence diode chips 5.
- the same method can also be used if the contact carrier 6 is replaced by a complete printed circuit board.
- the circuit board in the area of the luminescence diode chips 5 is provided with a housing 2 which is sprayed onto the circuit board.
- FIG. 3 shows a cross-sectional view through a modified exemplary embodiment of component 1.
- housing 2 is first formed and then the required conductor tracks 12 are produced on the surface of housing 2.
- the so-called CIMID technology can be used for this.
- a thin metal layer is first deposited in an aqueous solution on the surface of the housing 2 and then structured with a laser.
- the metal layer structured in this way is then thickened by electroplating.
- the use of this method has the advantage that the intermediate wall 11 can also be covered with a reflective metal layer. This further improves the efficiency of the component 1.
