Detailed description of the invention

Understand for technical characterictic of the present invention, object and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.

As shown in Figure 1 and Figure 2, be an embodiment provided by the invention, a kind of lighting device, comprises aluminium base 1, is fixed on the LED lamp 3 on aluminium base 1 and is sleeved on LED lamp 3 and is fixed on the lens 6 on aluminium base 1.As shown in Figure 1, LED lamp 3 is electrically connected with aluminium base 1 by two outward extending pins 4, and two pins 4 is respectively the positive and negative pin of LED lamp 3.As shown in Fig. 1, Fig. 3, Fig. 4, lens 6 comprise two relative supporting seats 62 that diffuser 61 and the end face along diffuser 61 stretch out fixing, diffuser 61 middle parts are provided with the incidence surface 611 of depression, form one can accommodating LED lamp 3 enter optical cavity, two supporting seat 62 correspondences offer the groove 621 that can hold pin 4.

For pin 4 can be contained in groove 621 preferably, preferred, as shown in Figure 1, Figure 3, groove 621 is U-shaped groove, and the notch of two U-shaped grooves is oppositely arranged.Understandable, groove 621 also can be arranged to semicircle, square, semielliptical shape or irregular shape.

Further, on the basis of technique scheme, in order to reach good light distribution effect, as shown in Figure 3, Figure 4, incidence surface 611 is arranged to ellipsoid, that is: entering optical cavity is semiellipsoid, because the major axis of ellipsoid is different from minor axis, LED lamp 3 is built in optical cavity, can realize the more bright dipping of wide-angle at the long axis direction of ellipsoid, eliminates illumination dead angle.Preferably, LED lamp 3 is positioned at the center into optical cavity.

Further, in order to expand LED rising angle, along incidence surface 611 center to edge, the radius of curvature of incidence surface 611 changes continuously; The scope of the radius of curvature of incidence surface 611 is 5.5mm-6.35mm.

Same, the radius of curvature of the exiting surface 612 of diffuser 61 also can affect the light distribution effect of LED lamp 3, concrete, as shown in Figure 1 and Figure 2, the exiting surface 612 of diffuser 61 is half ellipsoidal surface, and along exiting surface 612 center to edge, the radius of curvature of exiting surface 612 changes continuously.

Further, in order to strengthen LED lamp 3 intensities of illumination, reduce light loss, the scope of the radius of curvature of exiting surface 612 is 6.5mm-9.75mm.

The shape of diffuser 61 can affect lighting effect equally, and as shown in Figure 1 and Figure 2, the major axis of the exiting surface 612 of diffuser 61 is 1.5-2 with the ratio of minor axis.The diffuser 61 of semielliptical shape can expand lighting angle, strengthens light distribution effect; Meanwhile, the diffuser 61 of this shape can cover the pin 4 of pedestal 2 both sides preferably, avoids pin 4 to leak outside and is short-circuited, and eliminates safe hidden trouble.

Incidence surface 611 and the exiting surface 612 of diffuser 61 are ellipsoid, the set-up mode of two ellipsoids has considerable influence to light distribution effect, if incidence surface 611 be arranged in parallel with exiting surface 612, that is: the long axis direction of incidence surface 611 is consistent with the long axis direction of exiting surface 612, the short-axis direction of incidence surface 611 is consistent with the short-axis direction of exiting surface 612, this setup light loss is larger, bright dipping insufficient strength.In order to reduce light loss, expand lighting angle simultaneously, the long axis direction of the long axis direction of incidence surface 611 and exiting surface 612 arranges at an angle, as: 60 °, 75 °, 85 °.

Further, in order to be convenient to the setting of supporting seat 62 at minimizing light loss simultaneously, so that the pin 4 of LED lamp 3 has more preferably concealed space, the long axis direction of exiting surface 612 is vertical with the long axis direction of incidence surface 611, is 90 ° of settings.

Except technique scheme, the present invention can also arrange columned pedestal 2, and as shown in Figure 1, pedestal 2 is fixed on aluminium base 1, and LED lamp 3 is fixedly installed on pedestal 2, and pin 4 stretches out and is fixed on aluminium base 1 through the side face of pedestal 2.The part that two pins 4 are positioned at pedestal 2 inside is electrically connected with LED lamp 3, and the extension of pin 4 is connected with aluminium base 1.

Further, as shown in Figure 1, the formation of pin 4 is stepped, is convenient to the fixing of realization and aluminium base 1.For two pins 4 are contained in the groove 621 of supporting seat 62, preferred, the length range between the end of two pins 4 is 14.8mm-15.0mm.

In order to realize the fixed installation of diffuser 61 and aluminium base 1, as shown in Figure 1, Figure 3, on supporting seat 62, convex with leg 64, on aluminium base 1, depression is provided with screens groove 5, and lens 6 snap in screens groove 5 fixing with aluminium base 1 by leg 64.The shape of this leg 64 can be hook-shaped, L shaped or the font of falling T.

Further, under industrial environment, there is sustained vibration, in order to increase the resistance to shock of lens 6, prevent that lens 6 from, because coming off appears in undue oscillation, landing phenomenon, as shown in Figure 1, Figure 3, convexing with multiple reinforcing props 63 on the end face of diffuser 61.

Further, the quantity of reinforcing prop 63 is preferably 4, and 4 reinforcing props 63 are fixedly installed on the end face of diffuser 61 around entering optical cavity.The position distribution of 4 reinforcing prop 63 bodies also can play the effect of the pin 4 that blocks LED lamp 3.

On the basis of technique scheme, further, in order to make more LED ray cast entering in optical cavity to diffuser 61, effectively change the light angle on the end face that projects diffuser 61, on this end face, can be coated with frosted layer, or depression is provided with texture.

By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing from the scope situation that aim of the present invention and claim protect, also can make a lot of forms, within these all belong to protection of the present invention.
