Definitions
- the present invention relates to a LED dental lamp.
- the present invention relates to a LED dental lamp usable in dental ambulatories wherein it is necessary to integrate the diffused ambient light with a light beam localised on the patient's part to be visited (for example the mouth).
- Such type of lamp is a usually adjustable lamp generally mounted on a moving arm (so as to direct the light beam exactly on the selected spot) with predetermined intensity, frequency and colour temperature of the emitted beam.
- Such type of lamps is obtained by a halogen light and a reflecting mirror that focuses the optical beam on the desired target.
- Lamps of this type are also known wherein the light source is a LED and the optical beam is sent towards the target through collimators or conveyors comprised of as many lenses.
- European patent application EP1612471 describes such type of lamp.
- the optical beam is not sufficiently optimised and sometimes is not correctly directed towards the zone that requires being lighted most.
- the Applicant has perceived that if the light generated by the LED light sources is collimated and distributed through reflection rather than diffraction, the optical beam is optimised and directed with accuracy.
- An aspect of the present invention relates to a LED dental lamp comprising a lamp body including a concave seat provided with a pair of handles arranged at opposite sides of said half shells, said lamp body being associated to a support arm, characterised in that a plurality of support structures is arranged inside said seat, each comprising at least one LED light source whereto a reflecting element is associated.
- the lamp according to the present invention comprises a lamp body 2 preferably made in the shape of an oval half shell including a concave seat 21 and provided with a pair of handles 22 arranged at opposite sides of such half shell. Such handles are preferably engaged into the lamp body.
- the lamp body is associated to a support arm 3 comprising a rod 31 provided with multiple articulations and a fork 32 at the end whereof the lamp body 2 is constrained in an articulated fashion at such opposite sides whereto handles 22 are constrained.
- the lamp body can take different positions and orientate the light beam thereof in different positions.
- a plurality of support structures 4 is arranged inside said seat 21 of the shell and each comprises at least one LED light source 41 and a reflecting element 42 for each of said sources.
- Such reflecting element is a parabolic mirror.
- the LED light sources are ten.
- the LED light sources are of different colour and such lamp is provided with electronic piloting circuits for each LED capable of regulating the supply current to each of them.
- electronic piloting circuits for each LED capable of regulating the supply current to each of them.
- the lamp exhibits ten LED sources, eight are white light LEDs and two are LEDs respectively with yellow and red light.
- LEDs of different colour may be put next to the main LEDs 41 in each support structure 4.
