Abstract
The invention discloses a condensation light source module. The condensation light source module comprises a base, a high-power ultrahigh brightness light-emitting diode, a lens holder, a Fresnel lens and a light emitting port, wherein the high-power ultrahigh brightness light-emitting diode is arranged in the center of the base; the lens holder is arranged on the base and surrounds the light-emitting diode; the Fresnel lens is embedded on the front part of the lens holder, and a central axis of the Fresnel lens is coincident with the central axis of the light-emitting diode; and the light emitting port is detachably arranged at the front end of the lens holder. The condensation light source module can converge more light rays emitted by the high-power ultrahigh brightness light-emitting diode to improve the illuminance of light spots due to adopting the Fresnel lens; due to the fact that the light emitting port which can be detached and substituted is formed, the module can change the shape and the size of a light emitting hole thereof according to need to obtain projected light spots with different shapes and sizes; and the Fresnel lens is an ultrathin lens and occupies small space, which ensures that a structure of the condensation light source module is compacter.
Description
Technical field
The present invention relates to a kind of light source, relate in particular to a kind of condensation light source module.
Background technology
The light emitting diode of high-power super brightness has that long working life, energy consumption are low, the characteristics of device environmental protection.Along with development of semiconductor, the light emitting diode of high-power super brightness enters to be commercially produced in recent years.As novel light-emitting component, high-power superhigh brightness LED is widely used, and will substitute traditional light source gradually in the near future.
Fig. 1 is a kind of typical light emitting diode light source module of prior art, and it is made up of light emitting diode 11, base 12, concentrator 13.Light emitting diode 11 is installed on the base 12, and concentrator 13 is buckled on the glass-tube 111 of light emitting diode.The light that is sent by light emitting diode 11 converges by concentrator 13, projects the field of illumination.This is a kind of simple light emitting diode light source module, but will obtain different spot sizes in the field of illumination, must change concentrator 13, and will obtain different light spot shapes, and this light source assembly just can't satisfy.
Summary of the invention
Purpose of the present invention exactly in order to address the above problem, provides the condensation light source module of a kind of adjustable lay the grain spot size and light spot shape.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of condensation light source module, comprise base, high-power superhigh brightness LED, lens mount, Fresnel Lenses and light-emitting window, high-power superhigh brightness LED is installed in the base center, in lens mount is installed on the base and light emitting diode is enclosed in, Fresnel Lenses is inlaid in the front portion of lens mount, the central shaft of Fresnel Lenses overlaps with the central shaft of light emitting diode, and light-emitting window is removably mounted on the front end of lens mount.
Described light-emitting window comprises the shape of a plurality of light holes and the light-emitting window that varies in size.
The light hole of described light-emitting window be shaped as circular or square or other geometry.
Condensation light source module of the present invention makes it compared with prior art owing to adopted above technical scheme, have following advantage and and characteristics:
1, owing to adopted Fresnel Lenses, can converge the light that more sends, improve the illumination of hot spot by high-power superhigh brightness LED;
2, owing to be provided with the light-emitting window of detachable replacement, can change the shape and the size of its light hole on demand, to obtain the projected spot of difformity and size;
3, because Fresnel Lenses is a kind of ultra-thin lens, institute takes up space little, makes the condensation light source module structure more compact.

Fig. 2 is the structural representation of condensation light source module of the present invention;
Fig. 3 is the optical principle schematic diagram of condensation light source module of the present invention.
The specific embodiment
Referring to Fig. 2, Fig. 3, condensation light source module of the present invention comprises base 21, high-power superhigh brightness LED 22, lens mount 23, Fresnel Lenses 24 and light-emitting window 25.High-power superhigh brightness LED 22 is installed in the center of base 21 by screw 26, in lens mount 23 is installed on the base 21 by screw 27 and light emitting diode 22 is enclosed in, Fresnel Lenses 24 is inlaid in the front portion of lens mount 23, the central shaft of Fresnel Lenses overlaps with the central shaft of light emitting diode, and light-emitting window 25 is removably mounted on the front end of lens mount 23.
Light-emitting window among the present invention comprises the shape of a plurality of light holes and the light-emitting window that varies in size, and its shape can be circular or square or other geometry.Light-emitting window can be replaced as required, projects the shape and the size of the hot spot of field of illumination with control.
The optical principle of condensation light source module of the present invention after the light 31 that high-power superhigh brightness LED 22 sends converges by Fresnel Lenses 24, forms and converges light 32 as shown in Figure 3, and projects formation projected spot 33 on the illuminated area through light-emitting window 25.
