Compared with prior art, novel LED spotlight structure is by optical module, and optical module comprises the first lens and the second lens.These first lens have light collecting part, shine out after the light collection that LED light source is sent towards top, meet overhead illumination demand.Meanwhile, the some light that LED sends by these second lens, towards the direction refraction of this body of deflection, makes the side of the second lens, all there is bright dipping body neighboring, thus the LED spotlight structure making this novel has the advantage of wide-angle luminescence.
Accompanying drawing explanation
Fig. 1 is the sectional view of the novel LED spotlight structure of first embodiment of the invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
The novel LED spotlight structure 100 of first embodiment of the invention, please refer to Fig. 1.
Please refer to Fig. 1.Novel LED spotlight structure 100 comprises body 10, light source board 20, the LED light source 21 be arranged on light source board 20, and is arranged on the optical module at body 10 top.This light source board 20 is arranged on the top of this body 10, and this optical module is located at above this light source board 20.Therefore, the light 22 that this LED light source 21 sends forms required optical effect under the effect of this optical module.
This optical module comprises the first lens 30 and the second lens 40.These first lens 30 comprise light collecting part 31 and refraction part 32.The axis of the corresponding described LED light source 21 of this light collecting part 31 is arranged, to converge the light 22 of the close wherein near axis that described LED light source 21 sends.If the quantity of described LED light source 21 is multiple, then its axis is geometric center through described LED light source 21 and the axis vertical with this light source board 20.In general, this light collecting part 31 should be positioned at directly over described LED light source 21 or the position of departing from slightly.This refraction part 32 is arranged on the periphery of this light collecting part 31, the light 22 departing from wherein near axis that this refraction part 32 sends for reflecting described LED light source 21.So-called periphery: when this light collecting part 31 is bull's-eye, the loop configuration that this refraction part 32 is wholely set around this light collecting part 31 exactly; If this light collecting part 31 is the convex lens of bar shaped, so this refraction part 32 is exactly two strip structures being arranged on these light collecting part 31 both sides.These second lens 40 are arranged on this refraction part 32 periphery and to should refraction part 32 arrange, these second lens 40 are for reflecting towards the direction of this body 10 of deflection the light 22 sent from this refraction part 32.Like this, these first lens 30 have light collecting part 31, and the light 22 that LED light source 21 is sent shines out towards top after converging, and meets overhead illumination demand.Meanwhile, the some light 22 that LED sends by these second lens 40, towards the direction refraction of this body 10 of deflection, expand lighting angle, thus it is luminous to realize whole lamp wide-angle.
Preferably, these first lens 30 are rotation body structure, and this light collecting part 31 is convex lens structures, and this refraction part 32 is the loop configuration be wholely set around this light collecting part 31.The height that the height of this refraction part 32 is greater than this light collecting part 31 makes this refraction part 32 be combined to form an incident groove 33 with this light collecting part 31, and this incident groove 33 is just arranged described LED light source 21.This LED light source 21 is positioned at this incident groove 33, and the light 22 of the overwhelming majority that this LED light source 21 is sent can irradiate towards these the first lens 30, greatly improves optical efficiency.Further, the lateral wall of this refraction part 32 is the globoidal structure protruded towards these second lens 40.Therefore, this refraction part 32 is irradiated towards these second lens 40 after being converged by some light 22.
Further, these second lens 40 comprise ring wall 41, this ring wall 41 arrange around these first lens 30 and with this first lens 30 gap-forming gap, the external diameter of this ring wall 41 expands gradually on the direction away from this body 10.Because the external diameter bottom this ring wall 41 is greater than the external diameter of this body 10, this ring wall 41 the direction refracted ray that can realize towards this body 10 is set.The outer surface of this ring wall 41 is provided with spider web face.Like this, light 22, under the effect in spider web face, forms scattering at the outer surface of ring wall 41, makes whole light fixture have glittering and translucent, bright effect.
Please refer to Fig. 1, also comprise connecting portion 50, this connecting portion 50 is arranged between this ring wall 41 and this first lens 30, on this connecting portion 50 to should refraction part 32 penetrate light 22 be provided with diffusing structure 51.Preferably, this connecting portion 50 is loop configuration, and the top of this connecting portion 50 connects the top of these the first lens 30, and the bottom of this connecting portion 50 connects the bottom of this ring wall 41.This diffusing structure 51 is for being arranged on the multiple ledge structures on connecting portion 50 inner surface or outer surface.Like this, some light 22 through this connecting portion 50, then irradiates towards these second lens 40.Therefore, the first time scattering that light 22 is formed under connecting portion 50 acts on, forms second time scattering at the outer surface of the second lens 40 again.Light 22 is evenly distributed on the ring wall 41 of the second lens 40, there is advantage glittering and translucent, extremely attractive in appearance.
Please refer to Fig. 1.This optical module is transparent or semitransparent structure, and this optical module is made into integration by plastic material or glass material.Wherein, be preferably transparent configuration, glittering and translucent, bright effect can be made better.And optical module is made into integration, simplify optical texture, the cost of whole lamp and structure are all optimized.This optical module and this body 10 are made by plastic material, and this optical module and this body 10 are by ultrasonic bonding or use buckle to link together.
In sum, novel LED spotlight structure 100, by adopting that be made into integration, transparent optical module, simplifies optical texture, the cost of whole lamp and structure is all optimized.These first lens 30 have light collecting part 31, and the light 22 that LED light source 21 is sent shines out towards top after converging, and meets overhead illumination demand.Meanwhile, it is peripheral that these second lens 40 are arranged on this refraction part 32, and the outer surface of this ring wall 41 is provided with spider web face.Light 22 is evenly distributed on the ring wall 41 of the second lens 40, there is advantage glittering and translucent, extremely attractive in appearance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
