As the preferred embodiment of the invention, the inner space of described second lenticular body is cone shape, and first lenticular body is the circular arc body shape.
As the preferred embodiment of the present invention, the summit of the inner space of second lenticular body is positioned at the end face of first lenticular body.
As the improvement of the above-mentioned embodiment of the present invention, the degree of depth of the led light source accommodation space in first lenticular body is greater than the height of light source.
Led light source accommodation space in described first lenticular body can be the cylinder bodily form.
As the further improvement of the above-mentioned embodiment of the present invention, the incident bottom surface of led light source accommodation space is spherical shape.
Above-mentioned first lenticular body is provided with out wire casing, and this goes out wire casing and is communicated with the led light source accommodation space.
Above-mentionedly go out wire casing and be provided with two, two go out on first lenticular body that wire casing oppositely is arranged on led light source accommodation space both sides.
The invention has the beneficial effects as follows: the present invention organically combines first lenticular body and second lenticular body, the disperse light that LED sends is carried out secondary light-distribution, with the light extraction efficiency that promotes LED, the distribution of light that changes LED, the internal reflection surface of the plane of refraction by first lenticular body and the second lenticular body inner space makes light reflex to back bright dipping on the Lamp cup of light fixture simultaneously, too concentrated with the light of avoiding LED to send, prevent to dazzle the eyes dazzlingly because of light too concentrates on light source, the light that LED is sent is soft comfortable.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is a schematic perspective view of the present invention;
Fig. 2 is a cutaway view of the present invention;
Fig. 3 is a upward view of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, shown in the figure embodiment of use preferred for this invention, the lens that are used for the LED light fixture that present embodiment provides, comprise integrated first lenticular body 1 and second lenticular body 2, first lenticular body 1 is positioned at the end of second lenticular body 2, and the central shaft of first lenticular body 1 and second lenticular body 2 overlaps, be provided with the chimb 11 that radially extends along the bottom in the bottom of first lenticular body 1, chimb 11 is provided with mounting groove 111, the present invention can be fixedly mounted on the led light source top by the fixture that is arranged in this mounting groove 111.
As shown in Figure 2, in first lenticular body 1, has a led light source accommodation space 12, this led light source accommodation space 12 has the light of confession and enters the incident side 121 and the incident bottom surface 122 of first lenticular body 1, first lenticular body 1 has a plane of refraction 13, and this plane of refraction 13 can will project the light refraction of this plane of refraction to the light fixture Lamp cup from the incident side.
Led light source accommodation space 12 in first lenticular body 1 can be the cylinder bodily form, first lenticular body 1 can adopt the circular arc body shape, and the degree of depth of led light source accommodation space 1 is greater than the height of light source, to guarantee that led light source projects the light that reflects the side and can all be refracted on the light fixture Lamp cup through the superrefraction side again from the incident side.Certainly, the led light source accommodation space of first lenticular body also can be other polygon cylinder body shape, and first lenticular body also can adopt truncated conical shape, is not described further at this.
