Definitions
- the invention relates to a portable electric lamp powered by a DC power source, and comprising a housing enclosing: a lighting module with at least one LED, a user control member electrically connected to a first input of an electronic control circuit to define different lighting modes.
- the different functions of an LED lamp controlled by an electronic circuit are conventionally the adjustment of the power, the angle of focus of the beam, the color by selection of the LEDs, and the mode of permanent ignition or blinking . These functions allow the user to adapt their lighting to their environment by managing the consumption of electrical energy provided by the batteries. Access to one of these functions always requires the intervention of the user who must actuate the manual control device, either by pulses (pushbutton) or by pivoting (lever) or by translation (slide ).

- the electric lamp according to the invention relates to a portable lamp 10 comprising a housing BT enclosing an LED lighting module 11 disposed on the front face, and electrically connected to an electronic control circuit P, and 12.
- the illumination module 11 may be constituted by a single power LED (in the case of FIG. 3), or by a series of LEDs.
- the DC power source 12 is formed by a battery or batteries, arranged either inside the LV housing or outside the lamp in a separate housing.
- the invention is applicable to a headlamp, or a flashlight, with a LV housing of insulating material or metal.
- a user control member 13 is electrically connected to a first input E1 of the control circuit P for commissioning or shutdown, and the transmission of a manual setpoint or the input of parameters for the selection of the functions of the lamp 10.
- An optical sensor 14 is housed with the lighting module 11 in the housing BT of the lamp 10. The sensor 14 makes it possible to control the illumination captured after reflection on the object 16 of the light beam emitted by the LED.
- the sensor 14 is connected through an amplifier 15 to a second input E2 of the control circuit P.
- FIG. 2 represents by way of example the diagram of the signal S in microA delivered by the optical sensor 14 as a function of the illumination L in Lux.
- the signal diagram S is a substantially linear function being proportional to the illuminance L captured.
- the optical sensor 14 is constituted by a photosensitive receiver, for example of the photodiode, phototransistor, CCD or other type, which is located near the LED of the lighting module 11. It is noted in FIG. 1 that the rays R reflected by the object 16 are picked up directly by the optical sensor 14.
- the output signal S of the optical sensor 14 thus represents an image of the illumination of the object 16 and other external light sources. This signal S is interpreted automatically by the control circuit P, and is used as control input of the functions of the lamp 10.
- the optical axes of the LED and the sensor 14 are substantially parallel, so that the image of the illumination of the object 16 detected by the sensor 14 is the most representative.
- the type of optical sensor 14 is chosen to correspond to the response profile and the sensitivity of the human eye (bandwidth in the visible range between 450-700nm). This results in optimum visual comfort by an illumination sensation in the axis independent of the visualization movement of the illuminated object between two instants (for example card reading, then search for distant beacon).
- the optical sensor 14 detects the light from the LED of the lighting module 11 that it regulates.
- the light beam 17 emitted by the lamp 10 is thus automatically regulated without manual action to adapt the lighting to the environment, while managing energy consumption.
- control circuit P may be realized in different ways, in particular according to an analog or digital electronic circuit which will be described hereinafter as examples.
- the power of the lighting module 11 is determined by a pair of resistors R1, R2 connected to the LED at the terminals of the supply source 12.
- the first resistor R1 is in series with the LED, and the second resistor R2 is connected in parallel across the first resistor R1 by a switch 18, which is controlled by the output of a comparator circuit 19 Schmitt trigger type operational amplifier.
- the control signal S from the optical sensor 14 is applied to the input E2 of the comparator circuit 19.
- the other input E1 receives a reference value corresponding to the threshold of the comparator circuit 19.
- the switch 18 is open or closed so as to modify the value of the resistance in series with the LED diode. This results in a variation of the light power of the LED, including a maximum power, and a reduced power.
- FIG. 5 is a variant of FIG. 4, the two resistors R1 and R2 being connected in series with the LED, and the switch 18 being able to shunt the second resistor R2 as a function of the state of the comparator circuit 19.
- the operation is similar to that described previously. In both cases, there are two power levels of the LED automatically regulated by the optical sensor 14, which may be suitable for long lighting and short lighting.
- the electronic control circuit P may comprise several stages of analog comparator circuits 19 of different thresholds to obtain several power levels of the LED.
- the second embodiment of FIG. 6 represents a block diagram of a servocontrol circuit 20.
- the power of the LED is regulated by a power converter 21 having a modulation input controlled by a first manual setpoint C1 displayed by the controller. user in a first error circuit 22, and an automatic setpoint related to the response of the optical sensor 14.
- the set point C1 may correspond to a certain level of power desired by the user.
- the signal S delivered by the sensor 14 is compared in a second error circuit 23 with a second setpoint C2 corresponding to a desired level of illumination.
- the output signal of the second error circuit 23 is amplified in an amplifier 24, and applied to a third error circuit 25, which receives a measurement signal S1 of the intensity of the current flowing in a resistor R3 in series with the LED.
- the output of the third error circuit 25 is connected to the first error circuit 22 via an amplifier 26.
- the power of the LED is thus locked to the first manual setpoint C1, and to the automatic setpoint from the optical sensor 14 and the intensity of the current absorbed by the LED.
- This servocontrol circuit 20 makes it possible to preserve the illumination of the surface to be observed, and to adjust the electrical power by regulating the supply current of the LED according to the parameters of the environment.
- the digital control circuit P comprises a microcontroller 27 which manages the power of the LED according to the manual C1 setpoint, and the acquisition of the optical sensor 14.
- the flowchart is illustrated in FIG. 8, and comprises the following steps:
- the acquisition value of the optical sensor 14 is greater than the second setpoint C2. If at the same time, the power of the LED is greater than Pmin, the microcontroller 27 will control a decrease of x% of the power of the LED.
- the acquisition value of the optical sensor 14 is less than the second setpoint C2. If at the same time, the power of the LED is less than Pmax, the microcontroller 27 will control an increase of x% of the power of the LED.
- the presence of the optical sensor 14 makes it possible to maintain a constant illumination, regardless of the distance of the illuminated object and the movement necessary for the change of orientation.
- the eye of the user does not need to be accustomed, it is the lamp that takes care of it.
- a variable-focus lamp 100 comprises a lighting module 110 with two LEDs 1, LED 2 respectively supplying a narrow beam and a wide beam.
- the total available power is distributed by the outputs S1, S2 of the microcontroller 127 between the two LED1, LED2 according to the principle described in the document WO 2007/060319.
- the lamp 100 is equipped with three optical sensors 140, 141, 142, one of which has an optical system that captures only the light coming from the longitudinal axis of the lamp.
- the information delivered by the sensors 140, 141, 142 modulates the power distribution between the two LED1, LED2 so as to keep a constant ratio between the light received in the axis and the light received from both left and right sides.
