Limitation of the present invention.
Embodiment 1：
A kind of light fixture of angle adjustable, as shown in figure 1, including light source portion 2, light resource installing section 1, the first damper portion 3 and second
Damper portion 4.
Wherein light source portion 2 is lamp light source, and it is used for externally illumination, and light source portion 2 is overall in spherical.Light resource installing section 1 is then
It is fixed for fixed light source, and to whole light fixture.In order to when light source portion 2 output light adjustable angle, first damping
The damper portion 4 of portion 3 and second is arranged in light resource installing section 1, while to light source under the first damper portion 3 and the cooperation of the second damper portion 4
Portion 2 is clamped, and light source portion 2 is fixed in light resource installing section 1.
Describe for convenience, light source portion 2 is obtained and is wherein once defined as first side sideways, the first side can be light
One in preceding demifacet, rear demifacet, left demifacet or the right-half plane in source portion 2.It should be noted that the noun of locality in the present embodiment
It is based on for light direction.And be second side with the symmetrical side of the first side.First damper portion 3 and second
Damper portion 4 allows light source portion 2 to keep specific irradiating angle with not contacted with each other with two sides.
In order to provide enough pressure, the second damper portion 4 is also connected by elastomeric element 41 and the inwall of light resource installing section 1
Connect, in the presence of elastomeric element 41, the second damper portion 4 is formed with certain pressure to the surface of light source portion 2.When light source portion 2
When shooting angle needs adjustment, it is only necessary to apply strength manually and overcome pressure between the first damper portion 3 and the second damper portion 4 i.e.
The regulation of various angles can be realized.
Embodiment 2：
Improved as one kind of embodiment 1, the present embodiment and the difference of embodiment 1 are, as shown in Figure 2.The He of first damper portion 3
At least one is ring bodies or blocks among second damper portion 4.Wherein ring bodies is generally packing ring, when the first damper portion
3 and second damper portion 4 when being ring bodies, the radius of ring bodies should be less than the radius in light source portion 2, when the He of the first damper portion 3
The one side that second damper portion 4 then contacts damper portion with light source portion when being blocks is fitted completely or partially.The He of first damper portion 3
Second damper portion 4 be respectively fitted on the outer surface of light source portion 2 there is provided while enough dampings without regard to making rubber ring from another
End is slipped.
In the present embodiment, the material of the first damper portion and the second damper portion is wear-resisting plastic parts, can with but be not limited only to
For nylon etc..
In addition, in order to preferably fix the first damper portion 3 and the second damper portion 4, light resource installing section 1 can be set to for
Cylindrical shape, specifically, the cylindric internal diameter is more than the external diameter in light source portion 2, light source portion 2 can be rotated freely in it, simultaneously
The madial wall at the two ends of light resource installing section 1 each extends a platform, for convenience description be referred to as the first platform 11 with
And second platform 12, platform can be it is circular, the shape of platform preferably with the first damper portion 3 or the phase of the second damper portion 4
When due to the effect of platform, light source portion 2 is limited in inside light resource installing section 1 by the first platform 11 and the second platform 12.By first
Damper portion 3 is fixed on the first platform 11, and the second damper portion 4 connects the second platform 12 by elastomeric element 41, in elastomeric element
Under 41 elastic force effect, the close active force of oriented first damper portion 3 of the second damper portion 4, so as to tightly against light source portion 2 and incite somebody to action
Push the first damper portion 3 in light source portion 2.In other words, the first damper portion 3 and the second damper portion 4 formation clamp structure, by light source portion
2 clamp, and prevent light source portion 2 from arbitrarily being rotated in light resource installing section 1.
In the present embodiment, elastomeric element 41 is compression spring, and compression spring first end is connected with the inwall of light resource installing section 1,
Second end is connected with the second damper portion 4.
Because two damper portions are fitted the outer surface in light source portion 2 respectively, while light source portion 2 when under the thrust of elastomeric element 41
Stabilization is more uniformly stressed between damper portion, is more smoothed out when rotating light source portion 2.Even and if damping after long-term use
There is certain abrasion in portion, also can guarantee that good damping.
Embodiment 3：
The difference of the present embodiment and above-described embodiment 1 and 2 is, as shown in Figure 3.Install for convenience, the second platform 12 and light
Source installation portion 1 is detachable connection.Lateral surface specifically in the front end of light resource installing section 1 is provided with screw thread, while flat by second
The medial surface of platform 12 is also provided with corresponding screw thread, so that the second platform 12 is spirally connected with light resource installing section 1.It should be understood that
Can also be the modes such as clamping, welding or bonding in order to reach corresponding purpose, between the second platform 12 and light resource installing section 1
Engaged.
In order that output light shape is more regular, it is additionally provided with light shield 42, the present embodiment, light shield 42 is flat by second
Platform 12 extends along light source direction of illumination, and it is either detachably fixed to be designed with the second platform 12 for integral type.This implementation
Designed for integral type, simplify the overall structure of light fixture.
In order to easily facilitate distributing for heat, the rear demifacet in light source portion 2, which is set, is provided with cooling mechanism 21, and cooling mechanism 21 is stretched
Go out outside light resource installing section 1.Power line can also extend from cooling mechanism 21 simultaneously.
For the ease of regulation lighting angle, the front end in light source portion 2 is provided with telescopic lens arrangement 5.When need irradiation
During angle, lens arrangement 5 can be pulled out to form an angle adjusting mechanism, so that regulation angle is finer, while
Whole height can be reduced.It should be noted that the lens arrangement 5 can be the optical lens for possessing adjustment light type function,
Can be simple dust-proof planar transparent glass.High occasion is being required to light type, can use and possess adjustment light type function
Lens group, grating or coloured glass etc., governor motion is also had both the function of light type regulation.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Mode, can also be on the premise of present inventive concept not be departed from the knowledge that those of ordinary skill in the art possess
Various changes can be made.
