[0048] A. The first embodiment, including two beams, respectively a wide beam and a narrow beam

[0049] figure 2 The architecture of a lamp 200 showing a first embodiment of the invention - assumed to be a headlight - has a reactive or dynamic adjustment function for the light intensity produced by two beams 10 and 20 (narrow beam and wide beam respectively). This lamp 200 comprises a power unit 210 connected to a control unit 220, and a lighting unit 230 comprising a plurality of light emitting diodes LED, each equipped with its own focal system.

[0050] To simplify the description, in figure 2 In the example shown, a set of two diodes 231 and 232 are provided with supply terminals 233 and 234 respectively connected to the power unit 210 . Generally, in order to increase the brightness of the lamp, a larger number of diodes can be arranged in a single focusing optical system, and even a larger number of optical systems can be arranged to improve the usability of the lam...

[0099] B. Second embodiment, the lamp has two misaligned axes

[0100] image 3 show figure 2 An alternative embodiment of the illustrated embodiment in which the lighting unit 230 of the first embodiment is replaced by a set of two series LED diodes which are slightly off-axis. As shown, a first set of diodes (only one LED 331 is shown) produces a first light beam with axis 50 and a second set of diodes (only one LED 332 is shown) produces a second light beam along axis 60 . These two groups of diodes 331 and 332 are connected by the power unit 310 (with the figure 2 same as the power unit 210 in ) and controlled by the control unit 320 .

[0101] Although image 3 In the illustrated embodiment, there are only two groups of diodes and two shafts 50 and 60. Obviously, those skilled in the art can make appropriate modifications or changes to the present invention to produce more numbers of various geometric arrangements. beam.

Abstract

The invention relates to a portable lamp, a communication device, and a method of controlling illumination power of a portable lamp. The portable lamp comprises a communication device for exchanging identification data, configuration settings or control instructions with another portable lamp. More specifically, the communication device is used for avoiding exposition to glare.

Description

technical field [0001] The invention relates to the field of portable lamps, and more specifically relates to a portable lamp with an anti-glare system, a communication device, and a method for controlling the luminous power of the portable lamp. Background technique [0002] The applicant of the present application has already placed on the market a portable lamp (belonging to the headlamp category) with "reactive" or "dynamic" lighting characteristics as disclosed in PCT patent application WO2009 / 133309 . Simply put, as in figure 1 As shown, the headlight has at least one light-emitting diode 11 and an LED-type optical sensor 14 arranged adjacent thereto for sensing light signals reflected by a surface 16 of an object illuminated by the lamp. The control circuit 13 processes the signal to automatically control the power of the LEDs according to predetermined thresholds. In this way, it is possible to automatically adjust the light beam emitted by the lamp without manual...
