Below, most preferred embodiment of the present invention is just described, it is the contemplated best phraseology of the present inventor.Be appreciated that the present invention can revise in many aspects, and do not break away from essence of the present invention.Therefore, drawing and description itself are the character of giving an example, rather than determinate.
With reference to Fig. 1, it is first embodiment of room light, and it has a focus adjustment means, and room light of the present invention comprises a lamp housing 1, and lamp source just is arranged in its inside.
Lamp housing 1 comprises a hemispherical member 6, and it tiltably and rotatably is arranged on the opening 11, and opening 11 is formed in the closing panel 12, and light-reflecting components 4 is connected with hemispherical member 6.Hemispherical member 6 has an opening 13, and by this opening 13, opening 13 is formed on the part of hemispherical member 6 from the light positive of light source 14, and it extends towards vehicle inside by the perforate 11 of closing panel 12.The cylindrical flange dish passes through to extend downwards towards the hole 11 of vehicle interior.
What install on the interior circle of flange 28 is focus lens unit 10.That is, focus lens unit 10 comprise one have one with condenser lens 22 from the lens cylinder 30 of the coaxial longitudinal axis of the emission light of light source 14 and lens cylinder 30 end.Being an interior circular groove 29 on the inwall of flange 28, is an excircle projection 31 on excircle on the cylinder 30, thereby excircle projection 31 inserts interior circular groove 29 with being rotated, so that focus lens unit 10 is installed on the flange of hemispherical member 6.
As shown in Figure 2, inner guiding groove 18 be formed on along the inwall of lens cylinder 30 and form one spiral-shaped.Here, any shape that can move along the y direction guiding frame 8 of cylinder 30 can be used as guiding groove 18, and is not limited to spiral-shaped.Second end 16 of framework 8 is spheries, makes second end 16 can be easily inserted in the guiding groove 18.
The operation of the room light of above-mentioned description is described below with reference to Fig. 3.
Rotate from state shown in Figure 1 if its excircle projection 31 rotatably is inserted into the focus lens unit 10 of the interior circular groove 29 of flange 28, then second end 16 of lifting/lowering guiding frame 8 just descends along guiding groove 18, by first end, the 9 reduction lamp source 14 of framework 8.The rotation of focus lens unit 10 in the opposite direction will make lamp source 14 rise.
In above-mentioned situation, the distance between lamp source 8 and the condenser lens 22 can change by rotary-focusing lens devices 10, and the user can adjust the level of lamp source to his satisfaction.
Here, the bonding force of the excircle projection 31 of lens cylinder 30 is selected suitably, so that the rotation of focus lens unit 10 does not influence the location of hemispherical member 6.
After regulating above-mentioned light focusing by inclination and rotation hemispherical member 6, the user just can regulate direction of illumination.
With reference to Fig. 4.It is a room light of second embodiment of the invention.In the present embodiment, the outer guiding groove 18 ' of helix forms on the outer wall of the cylinder 30 ' of focus lens unit 10 ' along the y direction of cylinder 30 '.Guiding projection 31 is formed on the inwall of flange of hemispherical member 6 and is inserted among the outer guiding groove 18 ' of helix.
Cylinder 30 ' is put in the flange 28, and flange has a predetermined power friction coefficient, and in the time of lens 30 ' rotation, inaccurate cylinder 30 ' is removed from flange, and also inaccurate hemispherical member 6 moves.
With reference to Fig. 6 the operation of second embodiment is described, its state as shown in Figure 4, in the time of focus lens unit 10 ' rotation, along with the sliding guidance of guiding projection 31 ' along outer guiding groove 18 ', cylinder 30 ' rises, so that the distance shortening between lamp source 14 and the condenser lens 22, as shown in Figure 6.Rotary-focusing lens devices 10 has just strengthened the distance between lamp source and the condenser lens 22 in opposite direction.Therefore, the user is the focusing that can change light.
Only be most preferred embodiment of the present invention above, still, as mentioned above, the present invention can be used in various devices and the environment, and it can be changed or be modified within aforesaid concept of the present invention.
