Advantage.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the LED spotlight structure of first embodiment of the invention.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing.
The LED spotlight structure 100 of first embodiment of the invention, please refers to Fig. 1.
Please refer to Fig. 1.LED spotlight structure 100 includes body 10, light source board 20, the LED light being arranged on light source board 20
Source 21, and the optical module at 10 top of body is set.The top of the body 10 is arranged in the light source board 20, the optics group
Part is located at 20 top of light source board.Therefore, the light 22 which issues forms institute under the action of the optical module
The optical effect needed.
The optical module includes the first lens 30 and the second lens 40.First lens 30 include light collecting part 31 and refraction part
32.The central axes setting of the corresponding LED light source 21 of the light collecting part 31, to converge that the LED light source 21 issues close to it
Light 22 near central axes.If the quantity of the LED light source 21 be it is multiple, central axes be across the LED light source
21 geometric center and the axis vertical with the light source board 20.In general, which should be located at the LED light source 21
Surface or the position that is moved slightly away from.The periphery of the light collecting part 31 is arranged in the refraction part 32, and the refraction part 32 is for reflecting
The light 22 for deviateing wherein near axis that the LED light source 21 issues.So-called periphery：It is bull's-eye in the light collecting part 31
In the case where, which is exactly the ring structure being wholely set around the light collecting part 31；If the light collecting part 31 is bar shaped
Convex lens, then the refraction part 32 is exactly two strip structures for being arranged in 31 two sides of light collecting part.Second lens 40 are set
It sets in 32 periphery of the refraction part and corresponds to the refraction part 32 setting, which is used for towards the direction for being biased to the body 10
Reflect the light 22 issued from the refraction part 32.In this way, first lens 30 have light collecting part 31, so that LED light source 21 issues
Light 22 converge after shine out towards top, meet overhead illumination demand.Meanwhile second lens 40 issue LED
Some light 22 is reflected towards the direction for being biased to the body 10, expands light emitting angle, to realize that whole lamp wide-angle shines.
Preferably, which is rotation body structure, which is convex lens structures, which is ring
The ring structure being wholely set around the light collecting part 31.The height that the height of the refraction part 32 is greater than the light collecting part 31 makes the refraction
Portion 32 combines formation one incident groove 33 with the light collecting part 31, and LED light source 21 described in 33 face of incidence groove is arranged.It should
LED light source 21 is located in the incidence groove 33, the most of light 22 which is issued towards this
The irradiation of one lens 30, greatly improves optical efficiency.Further, the lateral wall of the refraction part 32 is convex towards second lens 40
Globoidal structure out.Therefore, it is irradiated after which converges some light 22 towards second lens 40.
Further, which includes ring wall 41, the ring wall 41 be arranged around first lens 30 and with this
One lens 30 interval forms gap, and the outer diameter of the ring wall 41 is gradually expanded on the direction far from the body 10.Due to the ring
The outer diameter of 41 bottom of wall is greater than the outer diameter of the body 10, and the direction towards the body 10 may be implemented in the setting of the ring wall 41
Refracted light.The outer surface of the ring wall 41 is equipped with spider web face.In this way, light 22 is under the action of spider web face, in the outer of ring wall 41
Surface forms scattering, so that whole lamps and lanterns have glittering and translucent, bright effect.
Referring to FIG. 1, further including interconnecting piece 50, which is arranged between the ring wall 41 and first lens 30,
The light 22 that the refraction part 32 injection is corresponded on the interconnecting piece 50 is provided with diffusing structure 51.Preferably, which is ring
Shape structure, the top of the interconnecting piece 50 connect the top of first lens 30, and the bottom of the interconnecting piece 50 connects the ring wall 41
Bottom.The diffusing structure 51 is the multiple step structures being arranged on 50 inner surface of interconnecting piece or outer surface.In this way, some light
22 pass through the interconnecting piece 50, are re-directed towards second lens 40 irradiation.Therefore, light 22 interconnecting piece 50 effect under formed first
Secondary scattering, and form second in the outer surface of the second lens 40 and scatter.So that light 22 is on the ring wall 41 of the second lens 40
It is evenly distributed, has the advantages that glittering and translucent, extremely beautiful.
Please refer to Fig. 1.The optical module is transparent or semitransparent structure, and the optical module is by plastic material or glass material
It is made into integration.Wherein, preferably transparent configuration, can make glittering and translucent, bright better effect.And one system of optical module
At optical texture being simplified, so that the cost and structure of whole lamp are all optimized.The optical module and the body 10 are by modeling
Material material is made, and the optical module and the body 10 are snapped connection together by ultrasonic bonding or use.
In conclusion LED spotlight structure 100 simplifies optics knot by using optical module be made into integration, transparent
Structure, so that the cost and structure of whole lamp are all optimized.First lens 30 have light collecting part 31, so that LED light source 21 issues
Light 22 converge after shine out towards top, meet overhead illumination demand.Meanwhile second lens 40 are arranged in the refraction
32 periphery of portion, and the outer surface of the ring wall 41 is equipped with spider web face.So that light 22 is distributed on the ring wall 41 of the second lens 40
It is even, have the advantages that glittering and translucent, extremely beautiful.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
