Abstract
The utility model discloses a spot light assembly with a Fresnel lens, which comprises a reflecting cup (1). The Fresnel lens (2) is arranged in the reflecting cup (1). The spot light assembly with the Fresnel lens utilizes the reflecting cup to perform curve reflecting collimation to light in an edge beam angle and simultaneously utilizes the Fresnel lens in the reflecting cup to perform collimation to light in a middle beam angle, thereby achieving collimating distribution of light in a light source full beam angle, completely removing floodlight aperture and enabling the light to be more collimated and concentrated. In addition, the light in the middle beam angle is distributed in collimation mode, the beam angle is small, and the smallest beam angel can reach four degrees, the long distance projection effect of concentration is enhanced, and a function of long distance projection of concentration of the spotlight is enhanced. The matching of the reflecting cup and the Fresnel lens is utilized to perform collimating distribution to the light in the light source full beam angle, production process is simple, production cost is low, and simultaneously production efficiency is improved.
Description
Technical field
The utility model relates to a kind of shot-light assembly, especially a kind of shot-light assembly that in reflector, has Fresnel Lenses.
Background technology
Conventional shot-light assembly generally is made up of sphere reflector or oval reflector, spot light and spherical lens.Light in the edge beam angle scope that it emits beam to spot light through sphere reflector or oval reflector carries out the camber reflection collimation, handles and the light in the spot light central light beam angle is carried out luminous intensity distribution.Therefore; This part of not carrying out that luminous intensity distribution handles only penetrates with the light beam than wide-angle; Form very big floodlight aperture around the hot spot, and this part light spot light light intensity the best part normally, the luminous flux of the significant proportion that accounted for; Cause luminous flux very low, this optically focused far throw function to shot-light is totally unfavorable.In order to strengthen the effect of optically focused far throw, can be with the depth design of reflector enough big, the light that spot light is sent carries out the camber reflection collimation through reflector entirely, but like this producting process difficulty is very big, and production cost is also higher.
The utility model content
The utility model technical problem to be solved is to provide a kind of shot-light assembly with Fresnel Lenses.The utility model can not only be eliminated the floodlight aperture, strengthens optically focused far throw effect, also has production technology and simply reaches the lower characteristics of production cost.
For solving the problems of the technologies described above, the technical scheme of the utility model is following: a kind of shot-light assembly with Fresnel Lenses is characterized in that: comprise reflector, reflector inside is provided with Fresnel Lenses.
In the aforesaid shot-light assembly with Fresnel Lenses, described Fresnel Lenses is arranged on the center line of reflector.
In the aforesaid shot-light assembly with Fresnel Lenses, the confocal point of described reflector and Fresnel Lenses, along is provided with light source.
In the aforesaid shot-light assembly with Fresnel Lenses, the extended line of the line at described focus and Fresnel Lenses edge and the reflective surface of reflector intersect.
In the aforesaid shot-light assembly with Fresnel Lenses, reflective surface edge three's line of described focus, Fresnel Lenses edge and reflector is a straight line.
In the aforesaid shot-light assembly with Fresnel Lenses, described light source is led light source, halogen light source or incandescent light source, also can be other spot light.
In the aforesaid shot-light assembly with Fresnel Lenses, the diameter of described Fresnel Lenses is smaller or equal to the base bore of reflector.
In the aforesaid shot-light assembly with Fresnel Lenses, the beam angle that described shot-light assembly penetrates is 4 °～5 °.
The beneficial effect of the utility model: compared with prior art, the utility model adopts reflector that the light in the edge beam angle is carried out the camber reflection collimation, and the Fresnel Lenses that is employed in simultaneously in the reflector collimates to the light in the middle beam angle; Realized the luminous intensity distribution that collimates of the light in the full beam angle of light source; Eliminated the floodlight aperture fully, collimation is concentrated more to help making light, and the light in the intermediate beam angle is by the collimation luminous intensity distribution; Make beam angle less; Minimum beam angle can reach 4 °, makes optically focused far throw effect strengthen, and helps promoting the optically focused far throw function of shot-light; Utilize reflector and Fresnel Lenses to cooperate the luminous intensity distribution that collimates of the light in the full beam angle of light source, it is lower that production technology comparatively simply reaches production cost, can also enhance productivity simultaneously.Characteristics such as high, the soft and light decay of the light uniformity that the utility model also has ejaculation is little.The utility model can also be applied to light fixtures such as industrial mine lamp.

The specific embodiment
Embodiment.A kind of shot-light assembly with Fresnel Lenses is characterized in that: comprise reflector 1, reflector 1 inside is provided with Fresnel Lenses 2.
Reasonable is that described Fresnel Lenses 2 is arranged on the center line of reflector 1; Described reflector 1 and Fresnel Lenses 2 confocal points 3 (focus that is reflector 1 and Fresnel Lenses 2 is overlapping), focus 3 places are provided with led light source, also can be halogen light source, incandescent light source or other spot lights.
Described focus 3 intersects with the extended line of the line at Fresnel Lenses edge 4 and the reflective surface 5 of reflector 1, can guarantee fully that the light in the intermediate beam angle can directly not penetrate, and eliminates the floodlight aperture fully.Best is, reflective surface edge 6 three's lines of described focus 3, Fresnel Lenses edge 4 and reflector 1 are a straight line, can guarantee that Fresnel Lenses just in time cooperates with reflector, makes production cost minimum.
The diameter of described Fresnel Lenses 2 prevents that smaller or equal to base 7 bores of reflector 1 light of the reflective surface camber reflection collimation of reflector from passing through Fresnel Lenses, has avoided reflecting of collimation light.
The beam angle that described shot-light assembly penetrates is 4 °～5 °, and beam angle is less, makes optically focused far throw effect strengthen.
