Abstract
The invention discloses a reflector lamp assembly with a Fresnel lens, and the reflector lamp assembly provided by the invention comprises reflective glass (1), wherein the Fresnel lens (2) is arranged in the reflective glass (1). Light in an edge beam angle is subjected to curved surface reflection collimation by virtue of the reflective glass. Meanwhile, the Fresnel lens in the reflective glass is used for collimating the light in a middle beam angle so as to collimate and distribute light for rays in the full beam angle of the light source and totally eliminate a floodlight aperture, thereby bringing convenience for collimating and concentrating the rays; meanwhile, the light in the middle beam angle is collimated and subjected to light distribution; the beam angle is small, and the minimum beam angle is 4 degrees, so that a light condensation long shot effect is enhanced, which is favorable for improving the light condensation long shot function of a reflector lamp; and the reflective glass and the Fresnel lens are matched to collimate and distribute light for the rays in the full beam angle of the light source. The reflector lamp assembly has the advantages of simple production technology, low production cost and improved production efficiency.
Description
Technical field
The present invention 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 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 by 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, around hot spot, form very big floodlight aperture, and this part light is spot light light intensity the best part normally, the luminous flux of significant proportion has 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.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of shot-light assembly with Fresnel Lenses.The present invention can not only eliminate 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, technical scheme of the present invention is as follows: 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, the focus place 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 °.
Beneficial effect of the present invention: compared with prior art, the present invention adopts reflector that the light in the edge beam angle is carried out the camber reflection collimation, adopt the Fresnel Lenses in reflector that the light in the middle beam angle is collimated simultaneously, realized the luminous intensity distribution that collimates of the light in the full beam angle of light source, eliminated the floodlight aperture fully, it is concentrated to help making light to collimate more, and the collimated luminous intensity distribution of the light in the intermediate beam angle, make beam angle less, minimum beam angle can reach 4 °, make optically focused far throw effect strengthen, help 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.The present invention also has characteristics such as the light uniformity height of ejaculation, soft and light decay be little.The present invention can also be applied to light fixtures such as industrial mine lamp.
