Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It is more easy to be readily appreciated by one skilled in the art with feature, so as to make the scope of protection of the utility model apparent define.
Embodiment 1：
A kind of low light loss Down lamp adjustment structure, as shown in figure 1, being connected between tube lamp light source portion 30 and whole light portion 40, use
In the governor motion as tube lamp light source output light inclination angle, the position that the adjustment structure is set turns with pin of the prior art
Shaft type adjustment structure position is identical.It includes arc guide portion 10 and sliding part 20.It is light that wherein arc guide portion 10, which is used for,
The angle modulation in source portion provides deflected trajectory.And sliding part 20 then slides in arc guide portion.
In terms of connection, arc guide portion 10 is connected in whole light portion 40, what the whole light portion 40 described in the utility model referred to
It is the part of Down lamp front end, it includes the fixed frame of reflector and fixed reflector, the light exported to light source portion 30 mostly
Line has corrective action, output light type is met the requirements.Sliding part 20 is then arranged in light source portion 30, and it connects with arc guide portion 10
Connect, and arcuately guide portion 10 can slide, so that the emerging beam in light source portion 30 is also carried out while angular adjustment
Horizontal displacement, being effectively reduced compared to pin rotary shaft of the prior art regulation because the point of rotation is too high caused
The loss of more light.
In addition, in the present embodiment, the arc core position of arc guide portion 10 is scheduled in whole light portion 40, now arc core position
The requirement of angular adjustment and displacement regulation can be met simultaneously by reducing, while have the scope for being unlikely to reduce angle adjustment.
Embodiment 2：
As the further optimization of embodiment 1, the present embodiment and the difference of embodiment 1 are：As shown in Figures 2 and 3, arc
Shape guide portion 10 includes guide portion support 11 and arc-shaped guide rail 12, and wherein guide portion support 11 is fixed in whole light portion 40, and
Arc-shaped guide rail 12 is then connected to the top of guide portion support 11.In order to facilitate the company between arc guide portion 10 and sliding part 20
Connect, the arc-shaped guide rail 11 in the present embodiment is arc convex ridge, and its cross section is shaped as circular or polygonized structure, this implementation
Example is rectangle.And sliding part 20 is then enclosed on arc-shaped guide rail 11, so that arcuately guide rail 11 moves sliding part 20.
In terms of the concrete structure of sliding part 20, sliding part 20 includes the first clamping part 21 and the second clamping part 22, changes
First clamping part 21 and the second clamping part 22, which coordinate, wraps arc-shaped guide rail 11, its other party of limiting light source portion in non-guide rail direction
To motion.Specifically, the first clamping part 21 is extended by light source portion 30, and connected in end and the second clamping part 22
Connect, so as to form a double team structure, and arc-shaped guide rail 11 is then clamped between the second clamping part 22 and the first clamping part 21.
In addition, connected between the first clamping part 21 and the second clamping part 22 by screw 50, in order to provide different dynamics
Chucking power, the elastic chucking power to adjust between the first clamping part 21 and the second clamping part 22 of screw 50 can be passed through.In order to
Prevent chucking power too small or excessive, can set a chucking power regulation spring 51 that the intensity of variation of chucking power is maintained into one
Individual rational scope, chucking power regulation spring 51 are enclosed on screw 50, and its both ends is respectively held against the head and the of screw 50
Two clamping parts 22, when screw 50 is tightened, chucking power regulation spring 51 is sternly compressed, so as to produce the pressure to the second clamping part 22
Power, increase the active force between the second clamping part 22 and the first clamping part 21, chucking power increase.Otherwise when screw 50 is unscrewed
When, the active force between the second clamping part 22 and the first clamping part 21 reduces, but because chucking power adjusts the effect 51 of spring,
The active force will not be reduced to zero, so as to avoid the too small phenomenon of chucking power.
Tighten up a screw 50 quantity of theory can complete chucking power regulation using one, but more uniform in order to obtain
Chucking power, the quantity of screw 50 can set two or more.
And governor motion of the present utility model is also similarly, its quantity can be one or two, when using two, amount
Governor motion is necessary symmetrical and is in one of lamp body simultaneously diametrically.
