the second wide & sit. The base is a printed circuit board. Therefore, the electrical connection point is in position and can be electrically contacted from the outside by controlled weaving. In addition, the base is better: the ^, / electrical connection point and control, and the weaving and lighting interconnection. Preferably, the base is also used as a field conducting element, and is adapted to operate on the bottom f. According to an embodiment of at least the π headlight, the automotive vehicle has at least a light-emitting diode. In addition, the automotive component has at least-controlled weaving for processing the measurement variable, and provides a current suitable for the signal to the Coach, and the LED system is mounted on the general base. on. According to at least the real component of the automotive component, the successor is dependent on the potential drop across the resistor, and the current of the light-emitting diode is mosquito-repellent. Therefore, the shunt resistor is connected to a series of light-emitting diodes. The control device can determine the current flowing through the light-emitting body via a potential drop across the known resistance. The actual value determined in this way can be compared to the nominal current value via the control device. Then, the control device re-adjusts the current flowing through the light-emitting diode in such a manner that the current flowing through the light-emitting diode is at least close to the nominal current value. Therefore, the nominal current value can be predetermined from the outside of the headlight of the car. The appropriate signal is injected into the control unit from the outside. By way of example, the signal is incident on the control device using a connector that is conductively coupled to the control device. The connector is thus preferably mounted on the base. The nominal current is preferably an infinitely variable. For example, t, the infinite variable of the light-emitting diode can be darkened according to the change of the nominal current value. According to at least one embodiment of the automotive headlight component, the automotive headlight component provides current to the light emitting diode in response to a signal measured by a temperature sensor of 1 1279341 degrees. The control unit is preferably also suitable for providing a control current to operate the temperature sensor. The temperature sensor generates an electrical signal according to the temperature of the light emitting diode. For example, if the temperature of the light-emitting diode exceeds the previously set maximum value, the control device reduces the current flowing through the light-emitting diode. When the maximum value is reached or exceeded, the control unit generates a fault signal. The fault signal is transmitted to the outside via the connector. According to at least one embodiment of the automotive headlight component, the temperature sensor is thermally coupled to the illumination body. That is, at least a portion of the heat generated by the light-emitting diodes during operation is transferred from the light-emitting diodes to the temperature sensor via thermal coupling. For example, the thermal transfer can be in the form of heat conduction, thermal radiation, or convection. Temperature sensors can be provided via one of the following components: NTCthermist〇r, PTC thermistor, infrared temperature sensor, diode (di) 〇de) 〇When a diode is used as a temperature sensor, the temperature can be determined by the temperature dependence of the forward voltage of the diode. According to at least one embodiment of at least the headlight component, the temperature sensor is mounted to the base. If the base is a printed circuit board, the temperature sensor is connected to the control unit using the transfer rails on the printed circuit board.

According to at least one embodiment of at least the automotive headlight component, the control device provides current to the light emitting diode based on the signal from the photodetector. In this embodiment, the control device is preferably operative to provide a control current to operate the optical detector. For example, the photodetector is a photodiode or a photoconverter and a photonic crystal. According to one embodiment of the automotive headlight component, the photodetector is used to detect substantially 1279341 electromagnetic beam emission emitted by the LED. The term "electromagnetic radiation emitted substantially by the light-emitting diode" means that a small amount of scattered light from the peak of the vehicle's touch element can also be transmitted to the light _||. _ 'The light side H is difficult to be slid to the position of the main electromagnetic radiation emitted by the light-emitting diode of the automotive headlight element. It is possible to determine whether or not all of the light-emitting diodes in the headlight component of the automobile can be used by using the intensity of the light gamma. It is also possible to determine whether the intensity of the Koda field of the light-emitting diode is weakened by the aging phenomenon by using a photodetector. The current through the light-emitting diode can be appropriately controlled by the control device. If the LED is faulty or due to aging, the intensity of the electromagnetic radiation emitted by the LED is greatly reduced, and the control device can generate a fault signal. The fault signal is transmitted to the outside via the connector. Therefore, it is better to mount it on the base. According to at least one embodiment of the automotive headlight component, the photodetector is mounted to the base. If the base is a printed circuit board, the light detector can be connected to the control device via a conductive switch on the printed circuit board to transmit signals and provide control current to the light detector. According to at least one embodiment of the automotive headlight component, the photodetector detects substantially _ ambient brightness. In this embodiment, the term "substantially ambient brightness" means that the optical debt detector is mounted on light that can be detected mainly from the outside of the headlight element. A small amount of scattered light from the headlight components of the car is transmitted to the photodetector. Such an external light detector can supply current to the light emitting diode in accordance with external light conditions. If the ambient brightness is reduced, for example, if the tunnel is passed, the current flowing through the light-emitting diode can be increased. When the ambient brightness increases, the current can also be attenuated. The current signal generated by the photodetector can be supplied to the control device via the connector. Therefore, the connector is preferably mounted on the base. If the base is a printed circuit board, the connector is connected to the control device by means of a conductive guide on the printed circuit board. 11 -1279341 The automobile headlight component preferably has a photodetector outside the headlight component to detect ambient brightness 'also - internal photodetector' to determine the intensity of electromagnetic radiation emitted by the LED .

The varistor is used to resist illuminating in the reverse bias direction: the body is electrostatically discharged. ~ According to at least one embodiment of the automotive headlight component, at least one 滤波器 type filter is mounted on the base. The π-type filter acts as a radio to prevent interference. According to at least one embodiment of the automotive headlight component, a pulse width modulation circuit is mounted on the base. The pulse width modulation circuit preferably dims the light emitting diode. The pulse width modulation circuit generates a current at a specific time interval, such as a specific time interval of one. At a specific time interval, no current flows through the light-emitting diode (1 corpse). The pulse width modulation thus produces an electrical square wave signal. The more the duty cycle (TrKT2) is, the longer the current flows through the light-emitting diode during the time interval A+T2, and the greater the brightness of the light-emitting diode. The frequency 1/(τ1+Τ2) is preferably at least 1 Hz, and the light emitting diode is continuously illuminated due to the inertia of the human being when processing the optical signal. According to at least one embodiment of the automotive headlight component, the control device is available. In order to set the pulse width modulation circuit, based on the external signal provided to the control device, the 12 1279341 control device can pre-slave the pulse-modulation circuit's guard cycle, thereby making the polar body infinitely variable. The required method is dimmed. According to at least the actual secret components of the car, the Lai County can be controlled by the current on the base.

In the embodiment, the light-emitting diode has five light-emitting diode chips connected in series, thus providing 17 volts to the light-emitting diode. The voltage is also mounted on the base as a further or additional boost/attenuation controller. According to at least one embodiment, the control device can be used to set the duty cycle of the DC converter.

Many other modifications and adaptations of the present invention can be made by those skilled in the art, and in particular, all combinations or novel features that are substantially equivalent to the present invention are not departing from the spirit of the present invention. It is included in the scope defined by the scope of the patent application and its equivalent. [Embodiment] In this embodiment, the LED chip 1 is mounted in a housing 2. External 20 1279341 The embodiment of the cover 2 may comprise a ceramic material. For example, the housing 2 has contacts that are contacted by a 143⁄4 photo-polar body wafer 1. In the illustrated embodiment, the outer cover 2 is mounted to the printed circuit board 25. For example, printed circuit board 25 has conductive shelves and contact points to contact the light-emitting diode wafer. For example, a light emitting diode chip is a thin film light emitting diode wafer as set forth in the Summary of the Invention. "Light-emitting diode chip 1 is connected to the light-emitting diode optical element 4, and the light-emitting diode light-emitting element 4 is a three-dimensional non-imaging (n〇n_imaging) optical concentrator, which is a complex & parabolic t-ener In the form of (Cpc), the light-emitting diode member 4 has a Xingchang injection port b through which the electromagnetic radiation 3 emitted by the light-emitting diode wafer can pass. At least part of the electromagnetic radiation 3 will be in the light-emitting diode optical element 4. Reflecting on the side wall, for this purpose, providing a reflective coating on the side wall. The radiation 3 exits the light-emitting diode optical element via the radiation outlet 5. When the radiation entrance b of the light-emitting diode optical element 4 is closer to the light-emitting diode The radiation output surface of the body sheet 1 is, the smaller the radiation inlet b is designed, and the higher the radiation spread of the electromagnetic radiation 3 appearing by the radiation outlet 5 is combined with the light-emitting diode optical element 4 and The light-emitting diode chip 1 constitutes a light-emitting diode 20. In the embodiment of the first figure, a plurality of optical diode members can be mounted along a line in the outer cover 2, for example, and Polar body wafer and general hair The diode optics 4 are joined (see Figure 4b). The second diagram shows the radiation through the light-emitting diode optics 4, the conical beam 6 being relative to the central axis 7 of the light-emitting diode optics 4, The exit port 5 is exited at a maximum angle 。. In this embodiment, the length 1 of the light-emitting diode optical element 4, at the width of the known radiation entrance b, determines the angle θ. By way of example, the law 21 -1279341 The small parabolic concentrator that is intended is as follows: 1 = 4 (1 + sin 2 ύη1 θ In order to reach the maximum beam angle, for example, θ = 9. The length of the light-emitting diode optical element ^ must be equal to about 23 times the size of the population b Width. ^The second figure shows a similarly-developed (Cp〇like) light-lued polymerizer, the side wall 8 of the light-emitting diode optical element, from the light entrance b to the radiation outlet 5 In the form of a straight line, in this embodiment, the t body of the light-emitting diode optical element 4 may be composed of a dielectric material, and its basic form has a truncated conical shape or a truncated gold-shaped earthy shape. Further, the light exit 5 is a ball. The shape of the or non-spherical lens is outwardly curved, and thus shaped Adding an additional light-emitting diode optical element 9 to become a part of the entire light-emitting diode optical component, reducing the divergence of the radiation 3 passing through the optical element 4. The fourth figure shows the automotive headlight component 4 A plan view of the first embodiment. • At least one light emitting diode 20 as shown in the first figure is mounted on the base 25. For example, the base 25 is a printed circuit board (for example, a metal core board). The base 25 has a main area of up to 30 mm x 60 mm, preferably up to 2 mm x 4 mm, and is preferably 15 mm x 30 mm. The shunt resistor 12 is connected to a series of light-emitting diodes 2 。. The potential of the resistor 12 is lowered to determine the current flowing through the LED 2 。. For example, control device 10 can include an integrated circuit to determine the current flowing through light emitting diode 20. The current flowing through the light-emitting body 20 can be set by the control device 22 1279341 10 on the basis of a nominal current value. The nominal current value of the control unit ίο can be determined by an external electrical signal. For example, the connector 16d can be coupled to the control device 10 to provide an external signal. When a suitable conversion (e.g., a start signal) is provided to the control device 10, current flows through the light emitting diode 20. The control unit can be provided with a conversion signal by means of the connector i6c. Further, by the connection with the connector 16f, the signal from the external photodetector 17 can be externally supplied to the control device 1A. Then, the control device 1 使 causes the current to flow through the light-emitting diode 20 in accordance with the brightness. Through the operating state of the LED 20, the signals provided by the photodetector 13 and the temperature sensor 14 to the control device 1 can be controlled according to the internal measurement variables. The temperature sensor 14 preferably generates a signal according to the temperature of the LED 2 . The signal from the temperature sensor 14 is passed through the control unit 1 and processed by the control unit 1 . Next, the control device 1 controls the current flowing through the light-emitting diode 2 in accordance with the signal. If the temperature of the light-emitting diode 20 is too high, the current flowing through the light-emitting diode 2 is lowered by the control device 10. The internal photodetector 13 determines the intensity of the electromagnetic radiation emitted by the light-emitting diodes 2''. The signal from the photodetector 13 passes through the control device 10. For example, if the intensity of the light-emitting diode 20 is lowered due to aging phenomena, the current flowing through the light-emitting diode 2 can be appropriately adjusted via the control device 1A. The sensation/controller 14 and the optical detector 13 are preferably fitted to the base 25. For example, the temperature sensor can be thermally coupled to the light emitting diode via thermal conduction using the base 25. The base 25 acts as a heat conducting element.
