Abstract
The invention discloses a light-emitting diode (LED) lighting module with a light guiding device. The LED lighting module with the light guiding device comprises an LED lighting unit which comprises a lamp head and a pin for supplying power for the lamp head. The light guiding device is arranged above the LED lighting unit and connected with the LED unit in a buckled mode. Due to the light guiding device connected with the LED lighting unit in a buckled mode and a first light guiding portion and a second light guiding portion of a cone of the light guiding device are used at the same time, the LED lighting module can greatly improve light guiding effect and light gathering effect of the whole light guiding device, enable light of the LED to be gathered effectively and reduce light leakage rate.
Description
Technical field
The present invention relates to a kind of lighting device, or rather, is a kind of LED illumination module with guiding device.
Background technology
LED takes from the triliteral abbreviation of Light Emitting Diode, and Chinese is translated into " light emitting diode ", as its name suggests, light emitting diode be a kind of can be that the electronic device of luminous energy has the characteristic of diode with electric energy conversion.The light leak rate of existing LED lamp is high, causes the significant wastage of light source and electric energy.
China's patent application 200810087113.4 discloses a kind of LED spotlight and has comprised: comprise the RGB-LED light source that is made of the red, green and blue light emitting diode and be used for throwing the collector lens to the incident end face of excellent lens from the mixed light beam convergence of RGB-LED light source; The tapered rod lens, its cross section converges to the outgoing end face from incident end face; Be used for to converge to as the emergent light of spot light outgoing from the exit facet of tapered rod lens the speculum on the axis of tapered rod lens.The light beam that incides the tapered rod lens when advancing in inside by the interreflection several times, thereby reduced at the brightness disproportionation at excellent lens exit end place and accelerated blend of colors, make light beam in any direction see it is all the white point light source outgoing of same color as color, and light beam is reflected the optically focused on the axis that mirror is converged to the tapered rod lens.The LED lamp of this optically focused, structure are too complicated, and particularly, still there is certain light leak in the connected mode of lens and luminescence chip.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby provides a kind of light leak rate extremely low LED illumination module.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of LED illumination module with guiding device, comprise a LED luminescence unit, described LED luminescence unit comprises lamp holder and the stitch of power supply supply is provided for described lamp holder, the top of described LED luminescence unit is provided with a guiding device, described guiding device and described LED luminescence unit engagement connection.
As preferred embodiment of the present invention, described guiding device comprises a light guide section, and is used for carrying the chassis and of described light guide section for the installation portion that fixedly mounts described light guide section, described light guide section is a cone, the top of described cone is provided with the outlet of penetrating for light, the middle part of described cone is provided with the first light guide section, outer one second light guide section that is arranged with of described cone, described the first light guide section by described the second light guide section be around.
As preferred embodiment of the present invention, described the first light guide section comprises the first projection that projects upwards and second projection of giving prominence to downwards, and the below of described the second projection has one for the burner cavity of holding described lamp holder.
As preferred embodiment of the present invention, described installation portion is provided with an installing hole.
Due to the LED illumination module utilization with guiding device of the present invention and the guiding device of LED luminescence unit engagement connection, utilize simultaneously the first light guide section and second light guide section of this guiding device cone, can greatly promote leaded light and the spotlight effect of whole guiding device, the light of LED is effectively assembled, reduced the light leak rate.
