Description

A kind of novel illumination module

Technical field

The utility model relates to a kind of lighting module, refers in particular to a kind of LED novel illumination module.

Background technology

Existing incandescent lamp flashlight usually have one towards the end face taper the lamp holder that broadens, section arranges one and constitutes parabolical concave mirror within it, in the focus of concave mirror incandescent lamp or its coiled-coil filament is set.This concave reflection minute surface be easy to contaminated or mirror surperficial because corrosion effect fades so that a little less than the reflection of light becomes.

Early stage LED torch has appearred on the market thereupon.This flashlight than incandescent lamp consumption still less the electricity and in most cases can carry out work with lower operating voltage so that little

Just enough as power supply.Particularly can the manufacturing structure mode by the employing light emitting diode

Flashlight carry together easily so that they can be used as key carrier etc.Except less power consumption, light emitting diode is for the impact that is subject to and impact and insensitively make it have the extremely long life-span, has avoided the essential trouble of often changing of early stage incandescent lamp.

And in some existing known flashlights, by a collector lens is set at the light outgoing plane, the position of light emission is arranged in the situation on the focus of this collector lens, basically can penetrate parallel light beam.If but a part of light that light emitting diode will be wherein towards the side namely with the angular emission higher with respect to its axis, these light can not be reflected utilization.

Therefore be necessary to invent a kind of novel complex optics lens, take full advantage of the advantage of LED and lens, so that the light that all LED send can both be fully utilized through reflection from lens/refraction, realize the purpose of energy-saving and environment friendly with this.

Summary of the invention

The purpose of this utility model is to provide a kind of small volume, novel illumination module easy to use.

For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows: a kind of novel illumination module, it comprises light emitting diode and complex optics lens, described complex optics lens comprise collector lens and the speculum that is extended to form to both sides by collector lens, described collector lens comprises convex basal plane and the convex outgoing plane relative with described basal plane, form a blind hole between described convex basal plane and the speculum, described light emitting diode can move axially by the optical axial along the complex optics lens in this blind hole.

The utility model lighting module compared with prior art has following beneficial effect: moving along the optical axial direction of complex optics lens with respect to blind hole by LED to change the different illumination characteristic that the light beam with different cone angle is regulated on ground.
