Abstract
The utility model discloses an LED lighting device with a light guide cover, comprising an LED light-emitting unit; the LED light-emitting unit comprises a hemispherical lens and an LED chip portion located below the LED light-emitting unit; an SMD pin for supplying power to the LED chip portion is arranged on the bottom of the LED chip portion; the LED light-emitting unit is arranged on the bottom of a light guide cover and is fixedly connected with the light guide cover. The LED lighting device provided by the utility model utilizes the light guide cover above the LED light-emitting unit to greatly improve light guide and concentration effects of entire light guide device, and effectively utilizes lights of LED to reduce light leak ratio.
Description
Technical field
The utility model relates to a kind of lighting device, or rather, is a kind of LED lighting device with light-guiding shade.
Background technology
LED takes from the triliteral abbreviation of Light Emitting Diode, and Chinese is translated into " light emitting diode ", and as its name suggests, light emitting diode is a kind ofly can the electronic device that electric energy is converted into luminous energy be had the characteristic of diode.The light leak rate of existing LED lamp is high, causes the significant wastage of light source and electric energy.
China's utility model application 200810087113.4 discloses a kind of LED spotlight and has comprised: comprise the RGB-LED light source that is made up of red, green and blue light emitting diode and be used for projection 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 and converge to the speculum on the axis of tapered rod lens as the emergent light of spot light outgoing from the exit facet 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 sees it all is the white point light source outgoing of same color as color, and the light beam mirror that is reflected is converged to the optically focused on the axis of 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.
The utility model content
The utility model mainly is to solve the existing in prior technology technical problem, thereby provides a kind of light leak rate extremely low LED lighting device.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of LED lighting device with light-guiding shade; Comprise a LED luminescence unit; Described LED luminescence unit comprises a hemispherical lens and the led chip portion that is positioned at described hemispherical lens below; The bottom of described led chip portion is provided with the SMD stitch that the power supply supply is provided for described led chip portion, and described LED luminescence unit is built in the bottom of a light-guiding shade and is fixedly connected with described light-guiding shade.
Preferred embodiment as the utility model; Described light-guiding shade comprises the connecting portion that a matrix and is positioned at described matrix below; The middle part of described connecting portion is provided with one and supplies first cavity of the hemispherical lens embedding of described LED luminescence unit, and the bottom of described connecting portion is provided with the stitch groove of the SMD stitch embedding that supplies described LED luminescence unit.
As the preferred embodiment of the utility model, the bottom of described connecting portion is provided with a pair of location that is used for described connecting portion location and gives prominence to.
As the preferred embodiment of the utility model, described light-guiding shade is the resin one machine-shaping of high light-conductive rate, and described location is outstanding processes for elastic caoutchouc.
Because the LED lighting device of the utility model utilizes the light-guiding shade of LED luminescence unit top, can promote the leaded light and the spotlight effect of whole guiding device greatly, the light of LED is effectively utilized, reduced the light leak rate.
