About realize lighting apparatus (lighting apparatus 10 of such as attached drawing) more details can same applicant on the same day
It is found in the two disclosures in Italian patent application specifications submitted.
In one or more embodiments, the integral ring-shaped shape of radiator 20 can be additionally included in main body 200 it
Between the bridge members 208 that extend.Therefore, advantage can be obtained from the presence of this structure, this structure is suitable for radiator
20 " machinery " stability contributes, and simultaneously participates in the dissipation role of the heat generated by the source L in operation (as wherein
A part).
In one or more embodiments, bridge members 208 can be to the light of the transmitting of the optical emitter L in lighting apparatus
The distribution of radiation executes forming function, and lighting apparatus generally includes:
Supporting member 16 with fork-like shape, including main part 160 and two fork tooth-like parts 162, this two forks
Tooth-like part carries opposed facing optical emitter L, has space therebetween (wherein, component 18 can be optionally inserted the space)；
And
Housing member, such as radiator 20 are arranged on fork tooth-like part 162, are had and are extended between fork tooth-like part 162
At one or more reflecting members (bridge members 208) of bridge like, the main part of light radiation towards supporting member 16 is reflected,
I.e. along the direction of the main part and therefore visual angle with reference to the accompanying drawings is reflected down.
One or more embodiments are contemplated that a pair of of bridge members 208, and the reflecting member is between optical emitter L
The two sides in space optionally symmetrically extend.
Particularly, in one or more embodiments, bridge members 208, which can be located at, leads to the master towards supporting member 16
The direct angle of reflection of body portion (so-called to hold seat) (that is, part extending therefrom of fork tooth-like part 162 of installation optical emitter L)
At maximum position, component 18 (such as lens) could be sandwiched in centre.
In one or more embodiments, bridge members can be implemented as crescent, have corresponding suitable for face
To the reflecting surface for being (for example) similarly crescent (crescent-shaped) (i.e. C-shaped) of optical emitter L.

By processing of aluminizing be made reflection (and reflecting surface 208a, and optionally, each surface of radiator 20 can make
At reflection).
Thus, it is possible to obtain mechanical device as figs. 3 and 4 illustrate, the light spoke emitted as a result, by optical emitter L
It penetrates:
A part emits (for example, if passing through lens there are lens) from lighting apparatus 10, without reflecting,
Another part by the upper surface 210 of the main part of supporting member 16 towards the external reflection of lighting apparatus 10,
Some passes through outside of the reflecting surface 208a towards lighting apparatus 10 and/or the main body towards supporting member 16
(at the upper surface, can be subjected to further reflecting before leaving lighting apparatus 10) is reflected in partial upper surface 210.
Under any circumstance, in one or more embodiments, pass through the shell structure being arranged on fork tooth-like part 162
The presence of part (such as radiator 20) and at least one reflecting member by extending to bridge like between fork tooth-like part 162
(such as bridge members 208), may be implemented for propagating by the mechanical device of the optical emitter L light radiation emitted, so as to towards branch
Support main part 160 (for example, towards the upper surface 210 for surrounding main part 160) reflected light radiation of component 16.
Therefore, in one or more embodiments for example including the reflector illuminated by lighting apparatus 10, relative to
The part directly emitted can increase the radiant section towards reflector, without being reflected.
Fig. 4 is at least exemplified in principle by keeping bridge members 208 mobile relative to lighting apparatus 10, and
In any case in the design phase of lighting apparatus 10, the position of adjustable bridge members 208 and/or orientation (be see, for example
The distance and angle [alpha] and α ' of d are expressed as in Fig. 3), will pass through the radiation profiles changed in all parts preceding listed
And the mechanical device in preceding description is modified, the light radiation emitted by optical emitter L leaves lighting apparatus 10 by the mechanical device.
It certainly, can be for mode only by way of non-limiting example herein in the case where not damaging basic principle
In the content changing that has been described realize details and embodiment, or even may obviously vary, without departing from the range of protection.
