15 PRIOR ART

WO2005005882 (Lahtinen) discloses, for example, an LED luminaire module suitable for a helmet having a plurality of adjacent LEDs, a body, an electronics control unit 20, and a body having a mounting arrangement consisting of two body parts between which the lip is adjustable and a tensioner. The disadvantage of current luminaire modules is that they use very low-power batteries, typically so-called. • coin-cell batteries with low capacity, which • •. the light output of the duel is relatively low and the burn time relatively short.

The invention will now be described in more detail by way of example with reference to the accompanying drawing, in which Figures 1a to 1b show a frontal and rear view of an occupational safety helmet module with 12 LEDs according to the invention;

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Figures 1a to 1b show an LED module 100 for a safety helmet or the like, mounted on its magazine, with 12 forward-facing LEDs 150-161 side by side, providing a very bright forward-looking LED module.

The module has a plastic body 101 and a sealed pa-20 grid housing 102 mounted thereon for transverse mounting of a preferably 9V battery (type 6IR61 e.g. rechargeable).

The body itself consists of two overlapping body members 103, ·: ··: 104, between which the lip can be fitted. Ko. the body members are somewhat jaw-like, about 5 cm in the flap direction and 10 cm in the transverse direction, and the magazine • · 25 can be threaded between them and tighten against the magazine to the thickness of the lip and. ···. tension determined by the height of the front wall 105. The final fastening is achieved by screws 106, which are screwed into the upper frame and which, by twisting, · ·· attach the module firmly to the magazine.

***** The battery compartment is sized to accommodate 30V 9V battery (or 2 AAA or AA fingertips if needed) and * ** connectors. The inside dimensions of the battery compartment are then such that the battery can be inserted ♦ ··, typically in the transverse direction of the module min 5 cm, height *: ***; nail min 1.8 cm and longitudinally 2.8 cm.

· · ·

The battery compartment has a housing part and a lid part 108 arranged by hinges 107 arranged on it.

• · * The LEDs are positioned adjacent to the front panel of the lower body • •. * · 109.

In addition, an electronic LED board with microprocessor is located inside the body (lower body), which functions as a control part having a resistor controlling each LED and a switch 110 controlling all functions of the luminaire, which is located below the lower body.

5 The luminaire is attached to the magazine with the LEDs pointing forward, illuminating the terrain in front of the person, for example, when moving in a dark forest. The luminous efficacy of the luminaire can be varied by changing the number of parallel LEDs lit simultaneously. The LED module can be mounted either inside the lip or above and / or below it.

In addition, the luminaire may have, in addition to forward-facing LEDs connected to the circuit board, downward-facing LEDs on the same circuit board or in a vertical circuit board. The circuit board may also have a switch-controlled twilight switch, the number of LEDs on, and LEDs operating in other directions, according to the desired control.

It will be apparent to one skilled in the art that the various embodiments of the invention are not limited to the example above, but may vary within the scope of the following claims. The module can be a waterproof (IP rating 55 and up) protective encapsulated LED module (motor vehicle, mine, work diving helmet). The module can also be equipped with 20 UV LEDs for official use (for verifying the authenticity of personal papers and other documents on the road, on the spot). Similarly, IR LEDs can be used for special functions. Vertical as well as azimuth orientation occurs manually. The twilight switch may, for example, operate by switching the light on · * /: from a switch that can be placed underneath the slip, and then the twilight switch controls ·: * ·: 25 LEDs according to the lighting conditions. In addition, the lamp: "* · may have green LEDs and red LEDs placed side by side so that they · · ·: \ t> indicate the direction of travel. The number of LEDs is red 2-8 white 4-24. '* ··. ROHS LEDs Figure 2 further shows the installation of the module according to Figures 1a and 1b • · in the helmet 300. The module may be provided with a charging plug 30 for charging the battery.
