Definitions
- the invention relates to a method and a circuit arrangement for generating mixed light of a predetermined color by mixing the longer-wavelength light emitted by at least one first LED with the shorter-wavelength light emitted by at least one second LED.
- the boundary between the longer-wavelength and the shorter-wavelength light may be, for example, 500 nm (with respect to the peak of the spectrum). It is known to produce mixed light of a predetermined color by mixing the light emitted by at least two LEDs, the light emitted from one LED and from the other LED having different wavelengths.
- white light can be obtained by mixing the light emitted by a red light LED and that of a color-converted blue light LED or UV light LED (this is, for example, a blue light or UV light-emitting LED chip with a Phosphor layer is covered, which converts the blue light or the UV light into a longer wavelength light with a correspondingly different color) are generated.
- a color-converted blue light LED or UV light LED this is, for example, a blue light or UV light-emitting LED chip with a Phosphor layer is covered, which converts the blue light or the UV light into a longer wavelength light with a correspondingly different color
- white light can also be generated by RGB (red, green, blue) mixture.
- a change in temperature can be caused by the ambient temperature fluctuating or even by the fact that the LED module is heated by the operating current over time. In the latter case, a stable state is reached only after a certain warm-up time. This is usually at least 10 minutes, but can take much longer.
- Color location changes of the mixed light result: the higher the temperature rises in an LED module, the lower the intensity of the light emitted by the LEDs (with constant current through the LED).
- the gradient of the intensity as a function of the temperature is decreasing or, in other words, the gradient is negative. This would not be a problem in terms of the color of the mixed light, if the negative gradient of the longer wavelength LED light and the shorter wavelength LED light would be about the same. In fact, however, the negative gradient of longer wavelength LED light is greater than the negative gradient of shorter wavelength LED light, with the result that the spectrum of the mixed light changes.
- the invention has for its object to counteract the described adverse phenomenon.
- the object is solved by the features of the independent claims.
- the dependent claims form the central one
- the invention proposes a method for operating a preferably electrically constant-current LED path which preferably produces white mixed light with at least two LED types of different spectrum.
- the Farbortwa ensures that the mixed light, which is caused by the different negative gradient of the temperature dependencies of the intensity of at least two different LED types, circuitry is reduced without the use of measurements and feedback variables.
- a compensation of the different negative gradients of the temperature dependencies of the intensity can take place by a preferably passive circuit branch connected in parallel to at least part of the LED path whose current profile essentially shows an inverse temperature gradient with respect to the intensity change to be compensated.
- the circuit branch may have at least one passive temperature-dependent component, in particular a PTC resistor and / or an NTC resistor.
- the PTC resistor or the NTC resistor may be part of a network (R1, R2, PTC) for controlling a transistor (T) whose base-emitter path (or drain-source path) lies in the circuit branch.
- the circuit branch may be connected in parallel to a part of the LED path which contains only one type of LEDs or which contains several different LED types.
- the LEDs of the first LED type (LED (r)) and the second LED type (LED (b)) may be connected in series or in parallel.
- the first LED type (LED (r)) can be an optional color-converted red, amber, orange, or infra-orange LED.
- the second LED type (LED (b)) can be an optional color-converted blue light LED or UV light LED.
- the invention also relates to an operating circuit for a preferably with constant current supplied LED track, which has at least two LED types of different spectrum for generating preferably white mixed light,
- the compensation circuit has a preferably passive circuit branch which is connected in parallel to at least part of the LED path and whose current profile essentially corresponds to an inverse temperature gradient. shows the intensity change to be compensated.
- the invention further relates to an LED module having such an operating circuit with a
- Constant power source and one of these supplied LED track.
- the invention also relates to an LED lamp, in particular for white light, comprising at least one such LED module.
- the LED lamp can be a retrofit LED lamp, which is designed to replace, for example, incandescent lamps, compact gas discharge lamps or halogen lamps, and having corresponding mechanical and electrical connections.
- FIG. 1 shows the temperature dependence of the intensity of the light emitted by a red-light diode and of the light emitted by a color-converted blue-light LED
- Figure 2 shows a basic circuit arrangement with a
- PTC resistor for producing white mixed light by mixing the light emitted by red LEDs and the color-converted blue LEDs, and with a PTC resistor to compensate for the different temperature dependency of the efficiency of the two types of LED mentioned.
- FIG. 3 shows a modification of the embodiment of FIG.
- FIG. 4 shows a basic circuit arrangement as in FIG.
- LED chain LED6-10 with a blue LED from the LED chain LED1-5 is reversed.
- FIG. 5 CIE coordinates for different luminous fluxes
- LEDs that emit red light are representative of longer wavelength LEDs
- blue light emitting LEDs also referred to as “blue or color converted blue LEDs”
- FIG. 1 shows the natural or uncompensated profile of the intensity of the light emitted by red LEDs as a function of the temperature (of the semiconductor junction) as a dotted curve (in each case at constant current).
- the natural course of the intensity of the intensity of the light emitted by blue LEDs is shown as a continuous drawn curve. It can be seen that both curves decrease with higher temperature, but the negative gradient of the intensity profile of the red LEDs is greater than that of the intensity profile of the blue LEDs.
- the negative gradients of the two intensity gradients should be largely aligned. Otherwise, fluctuations in the room or ambient temperature or, after switching on, heating of the LED module to the operating temperature result in an undesired color shift of the mixed light.
- the solution to this problem is according to the invention in a circuit compensation control (as opposed to a control) of the intensity profile of the light emitted from the red LEDs such that the negative gradient of the light emitted by the red LEDs is lowered so that it at least until Reach the operating temperature is approximately parallel to the intensity curve of the light emitted by the blue LEDs light.
- the compensated intensity profile of the light emitted by the red LEDs is shown as a dashed curve.
- circuit-technical control excludes a color detection by means of a sensor and feedback signal, so that the invention provides a circuit-type control without regulation with a feedback signal.
- FIG. 2 shows a circuit arrangement with which such a compensation can be achieved.
- This circuit can be fed by a preferably regulated constant current whose amplitude of the dimming of the LED track can be adjustable, for example by specifying a desired value.
- the circuit may, for example, be accommodated in a housing of a retrofit LED lamp.
- the circuit arrangement includes a plurality of blue LEDs connected in series, denoted by LEDS (b), and also a plurality of red LEDs connected in series, denoted by LEDs (r).
- a bypass circuit branch is connected in parallel, which consists of a transistor T and a resistor Rl.
- Parallel to the emitter-base path of the transistor T is a resistor R2.
- the temperature-sensitive resistor PTC has a positive temperature behavior, ie its resistance increases with temperature and vice versa.
- the temperature-sensitive resistor PTC is in heat-conducting contact with the chip or module on which at least the LEDs (r) are arranged.
- the LEDs (b) can also be arranged on this chip or module.
- the resistance value of the temperature-sensitive resistor PTC also increases, with the result that the Emitter-base voltage of the transistor is lowered.
- the transistor increasingly blocks, reducing the partial current of the total current flowing across the bypass. This means that the current flowing through the LEDs (r) is increased, which then leads to the desired reduction in the negative gradient of the intensity profile of the light emitted by the LEDs (r).
- the network for generating a control voltage for the transistor T are also designed differently and can be realized for example with a temperature-sensitive device having a negative temperature behavior.
- a further possibility for compensating the intensity profile of the light emitted by the LEDs (r) is that the forward voltage of at least one "red” LED and / or at least one "blue” LED, optionally all LEDs of the chain, with temporarily stabilized operating current Temperature measurement ("red” and “Blue” is just an example of the first or second type.) By evaluating the measured forward voltage, one can then obtain a control parameter to increase the operating current.
- FIG. 3 also shows a circuit arrangement with which the compensation described above can be achieved.
- the circuit arrangement includes a plurality of blue LEDs connected in series, denoted by LEDs (b), and a plurality of red LEDs also connected in series, denoted by LEDs (r).
- LEDs (r) To the LEDs (r), a bypass circuit branch is connected in parallel, but in this embodiment, instead of a PTC, has an NTC with a negative temperature behavior, i. its resistance lowers with temperature and vice versa.
- the temperature-sensitive resistor NTC is in heat-conducting contact with the chip or module, on which at least the LEDs (r) are arranged.
- the LEDs (b) can also be arranged on this chip or module.
- the three components of the functional unit R1-NTC-R2 supply the base of the transistor Tl with temperature-dependent current and temperature-dependent voltage, wherein the resistor Rl with the parallel resistor R2 and the temperature-sensitive resistor NTC forms a voltage divider for supplying the base.
- the resistor R2 serves to limit the current in the lower temperature range and thus deforms the current characteristic of the sidestream.
- Rl a side current to supply the transistor base and the voltage level is set depending on the existing voltage.
- the NTC causes the current in the sidestream to switch off at high temperatures. At low temperatures, the effect Current amplification of the transistor with correspondingly low currents through the side string current limiting.
- the functional unit T1-R3-R4 represents the current control unit.
- the transistor is intended to switch large currents. For this reason, the linear current amplification factor is an essential quantity.
- the two resistors R5 and R6 cause the current limit at temperatures of 40 ° to 20-30 ° and consume the most power. For this reason, a low power transistor (0.5W) can be used.
- the resistors have the disadvantage that the dimensioning may require a large area.
- a higher power transistor can be used and the resistor either omitted entirely or the design performed such that there is no current limiting and only a portion of the power is dissipated.
- FIG. 4 shows a further exemplary embodiment based on FIG. 3, wherein, however, in the LED chain, a red LED is connected in the chain of blue LEDs by interchanging.
- the compensation ratio of the compensation circuit changes, since the compensation current thus no longer concerns only the red LEDs, but also a blue LED.
- the compensation circuit can thus be set to the desired temperature behavior such that, in addition to the resistance circuit, the properties of the NTC / PTC and the transistor amplification, the arrangement of the different colored LEDs in the LED string is changed. It depends in particular on which LEDs following the branch point for the
- a particular field of application for such a temperature-compensated circuit are again retrofit LED lamps.
- FIG. 5 shows CIE color coordinates for different compensation currents as a function of the temperature TC at the temperature-dependent resistor NTC in 5-degree increments.
- a typical temperature gradient of 25 degrees to 85 degrees shows that the Earbort in the CIE diagram remains within a given McAdam ellipse of a defined color temperature (for example, 2700 Kelvin) during heating.
- the McAdam ellipse shows the tolerance range of the human eye for a given point in the CIE diagram.
- the human eye does not perceive any color change.
- the compensation is even better at lower temperatures up to 60 ° than in the constellation according to FIG. 3 with unexchanged LEDs, but then a very strong shift occurs and the compensation is no longer sufficient. To counteract this, a steeper drop would have to be achieved up to 75 ° to approximately 0mA sidestream.
