Drawings
Embodiments of the present invention are described below with reference to the accompanying drawings, in which:
fig. 1 is a schematic perspective view of a lens unit of the zoom miner's lamp provided by the present invention.
Fig. 2 is a side sectional view of the zoom miner's lamp provided by the present invention.
Detailed Description
The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Referring to fig. 1 and 2, the zoom miner's lamp provided by the present invention includes a circular lens unit 10, a zoom adjusting ring column 20 connected to the edge of the lens unit 10, a fixing ring column 30 connected to the zoom adjusting ring column 20 by a screw thread, an LED driving circuit board 40 vertically connected to the inner side wall of the fixing ring column 30, and a plurality of LED lamps 50 disposed on one side of the LED driving circuit board 40 facing the lens unit 10.
One side of the lens unit 10 facing the LED driving circuit board 40 is a first planar lens 11, one side of the lens unit far away from the LED driving circuit board 40 is provided with a plurality of annular plano-convex lenses 12, the plurality of annular plano-convex lenses 12 are concentrically arranged, and the diameters of the annular plano-convex lenses 12 gradually increase from inside to outside. The middle of the side of the lens unit 10 away from the LED driving circuit board 40 is a second planar lens 14.
At least three mounting posts 15 are arranged at intervals on the circumferential edge of the lens unit 10, and a first through hole 151 is opened in the middle of the mounting posts 15.
The inner side wall of one end of the zoom adjusting ring column 20 is provided with a connecting column 21 corresponding to the mounting column 15 in a protruding manner, and the connecting column 21 extends into the first through hole 151 of the mounting column 15.
The inner side wall of the zooming adjusting ring column 20 is also provided with an internal thread, the outer side wall of the fixed ring column 30 is provided with an external thread, and the internal thread of the zooming adjusting ring column 20 is in threaded connection with the external thread of the fixed ring column 30. When the zoom adjustment ring post 20 is rotated, the zoom adjustment ring post 20 may move in the axial direction of the fixed ring post 30, thereby adjusting the distance between the lens unit 10 and the LED lamp 50 to achieve zooming. In other embodiments, the zoom adjustment ring post 20 may be slidably connected to the fixed ring post 30 to adjust the distance between the lens unit 10 and the LED lamp 50.
The circumferential edge of the lens unit 10 is further provided with a sealing groove 16, a sealing ring 60 is arranged in the sealing groove 16, and the outer side of the sealing ring 60 abuts against the inner side wall of the zoom adjusting ring column 20. So can avoid outside water to get into through the clearance between lens unit 10 and the adjusting ring post 20 that zooms the utility model provides an inside of miner's lamp zooms to protection LED drive circuit board 40 and LED lamp 50.
The LED lamp 50 has a plurality of circumferential LED lamps 51 and a central LED lamp 52, and the central LED lamp 52 is disposed at the center of the side of the LED driving circuit board 40 facing the lens unit 10. A plurality of circumferential LED lamps 51 are annularly distributed around the central LED lamp 52.
In the present embodiment, the circumferential LED lamps 51 are divided into a plurality of annular LED lamp groups, and each LED lamp group corresponds to one annular plano-convex lens 12, that is, the diameter of each LED lamp group is the same as the diameter of the corresponding plano-convex lens 12. A plurality of annular LED banks all set up concentrically.
The radiation angle of the light that circumference LED lamp 51 sent is 180 degrees, and most light that circumference LED lamp 51 sent takes place the refraction and focuses on plano-convex lens 12, so make the light that circumference LED lamp 51 sent be annular focus, and light is the annular and distributes, and can not too concentrate on a bit, and luminance is comparatively even, and illuminating effect is good. Part of the light rays of the circumferential LED lamp 51 directed to the second planar lens 14 may pass directly through the second planar lens 14.
The light rays of the central LED lamp 52 with a smaller radiation angle directly pass through the second planar lens 14, and the light rays with a larger radiation angle are focused by the plano-convex lens 12.
Since the light condensing function of the adjusting lens unit 10 is realized by the plurality of plano-convex lenses 12, the whole thickness is uniform, the thickness of the middle part is not thick, and thus, the lens material can be saved.
