Refering to shown in Fig. 4 to Fig. 7, in other embodiments, can will be helped via the tilt angle for changing concentric circles fin
In the adjustment of light beam angular region, for example, refering to the side flood lighting figure of Fig. 7 C, in other embodiments, second is increased
The tilt angle of the concentric circles fin of embodiment, so that beam angle is controllably formed between 30 to 80 degree；Increase based on this and again
Add tilt angle, beam angle can be controlled between 70 to 110 degree (with reference to shown in Fig. 7 E), it is noted that Fig. 7 E is basis
Its purposes and the flood lighting figure on being under (over the ground).
It should be noted that the present invention is not limited for the beam angle of accurate control Projecting Lamp reflection light with above-described embodiment,
Without prejudice under spirit of that invention, the tilt angle of bigger concentric circles fin can be set to increase beam angle, make Projecting Lamp more
Has effects that wide-angle.In one embodiment, the density of concentric circles fin can more be increased to promote Projecting Lamp effective lighting range
The uniformity.
The use of control light part is to cause environment light harmful and effectively control to increase reflection light utilization rate and reducing invalid light
Vision dazzle.For example, control light part extend reflecting element, can reflection light, to increase the ratio of reflection light, and can prevent
The dazzle of part direct light and reflected light.Illustrate below by different embodiments, Fig. 9-Figure 16 setting control light part structure with
Increase reflection and anti-dazzle.
3rd embodiment
Fig. 9 and Figure 11 is that embodiment illustrates that controlling light part extends out schematic diagram one of according to the present invention.Control light part extend reflecting element and to
Outer expansion is in favor of a plurality of light of concentration.Refering to shown in Fig. 9-10, in this embodiment, control 33 lotus root of light part connects reflecting element 32,
For example, the connection of control light part 33 extends reflecting element 32 and expands outwardly.Light source 31 issues a plurality of light, part of light
It is reflected through reflecting element 32, part direct line 34 reflects without reflecting element 32 and is reflected as reflection light via control light part 33
35, therefore control light part 33 can increase the ratio of reflection light 35, concentrate light, also that is, reducing invalid diffusion ratio.Another party
Face can not look at light source straight on many sight angles, there is the effect of anti-dazzle since the control extension of light part 33 is extended out.
Refering to fig. 1 shown in 1-12, in other embodiments, control light part 33 has partial notch, so that direct light can appear,
For example, the partial notch below light part 33 with one third is controlled.This notch is the illumination to Projecting Lamp short distance, example
Such as in long distance light projector, the brightness for being still able to maintain lower edge near Projecting Lamp can be the utilization of proximal end or other illumination purposes.
Fourth embodiment
Figure 13 and Figure 15 is that embodiment illustrates that controlling light part inside contracts schematic diagram one of according to the present invention.Control light part extends the reflecting element simultaneously
To inside contracting in favor of eliminating the part of a plurality of light.Refering to fig. 1 shown in 3-14, in this embodiment, control 33 lotus root of light part is reversed
Reflecting element part 32 is penetrated, for example, the control connection of light part 33 extends reflecting element 32 and inside contracts outward.Light source 31 issues plurality of lights,
Part of light is reflected through reflecting element 32, though part direct line 34 is reflected without reflecting element 32, incidence control light part 33
When, because control light part 33 has delustred coating or delustring material, direct line 34 can be eliminated, the light being without the use of is reduced, changes speech
It, also reduces invalid diffusion ratio.On the other hand, it since the control extension of light part 33 extends out, can not be looked at straight on many sight angles
Light source has the effect of anti-dazzle.
Refering to fig. 1 shown in 5-16, in other embodiments, control light part 33 has partial notch, so that direct light can appear,
For example, the partial notch below light part 33 with one third is controlled.This illumination of notch system to Projecting Lamp short distance, example
Such as in long distance light projector, the brightness for being still able to maintain lower edge near Projecting Lamp can be the utilization of proximal end or other illumination purposes.
It should be noted that concentrating to increase anti-dazzle or light, the effect of delustring, the present invention is not shown in above-described embodiment
Control light part length be limited, without prejudice under spirit of that invention, the control light part of long version, short version, arc or abnormity can be set.
In conclusion varifocal light projector device of the invention, adjusts light source position using focusing mould group, recycles anti-
It penetrates part and controls the reflection light that the combination accurate control light source of light part emits beam, it is remote to adjust light beam angular region, adjustment light projector
Closely, light, delustring and anti-dazzle are concentrated, so that light is effectively reached specified area to be illuminated domain, adapts to the use of various environment.
