Abstract
An illuminating apparatus comprises a lampshade, a socket seat, a light guide plate, a reflecting layer and a plurality of base plates, wherein, the socket seat has tube shape and is installed inside the lampshade; the light guide plate is used for mixing light and is arranged between the lampshade and the socket seat; the reflecting layer is arranged between the lampshade and the light guide plate; the base plates are respectively provided with an LED and arranged on the socket seat; in this way, a light source is emitted to the reflecting layer from smaller area, and is expanded to be larger area by the reflection of the reflecting layer, so as to overlap in the light guide plate to achieve the effect of mixing light, thus leading point light source to be translated into surface light source.
Description
Technical field
The present invention relates to a kind of lighting device, refer to that especially a kind of application light emitting diode (LED) throws light on, increases light-source brightness and makes light source lighting device more clearly.
Background technology
Traditional tengsten lamp, the light source that it sent is a scattering state, thus can throw light on to the brightness that its context produces to a certain degree, but traditional tengsten lamp has the shortcoming of power consumption, in view of this, the light emitting diode (LED) with power saving just replaces traditional tengsten lamp gradually.
Yet the light that existing light emitting diode sent is linearity, but not dispersion shape, the light of linearity only can converge at a place, and other context light can't converge, and luminance shortage will seem.
In view of this, so just there is the dealer to propose to improve, announcement has a kind of " using the lampshade of light emitting diode " as TaiWan, China letters patent book number M317545 (date of declaration August 21 2007 Christian era), include circuit board, light emitting diode, refractive body, this light emitting diode is welded in the end of this circuit board, this refractive body is formed with groove with respect to the light emitting diode position of circuit board, the opposed inner walls face of groove is a reflective surface, and the bottom face in groove is formed with the perforation that can supply light emitting diode to run through in addition.Whereby, the light that light emitting diode is sent is dispersion shape, enlarges the area of light irradiation, increases brightness.
Though above-mentioned " using the lampshade of light emitting diode " can increase the brightness of light, it also fails to overcome the problem that can produce multiple little shadow when lampshade shines.The encapsulation of light emitting diode mainly has three kinds in a glue, embedding, mold pressing, and the problem of light emitting diode stain is to produce in the above-mentioned processing procedure, and the light that stain can make light emitting diode emit produces multiple little shadow, influences illuminating effect.
So the inventor is thoughts on the part improved of above-mentioned defective, concentrate on studies and cooperate the utilization of scientific principle, propose a kind of reasonable in design and effectively improve the technical solution of the present invention of above-mentioned defective finally.
Summary of the invention
Main purpose of the present invention provides a kind of lighting device, and its structural design can overcome multiple little shadow that lumination of light emitting diode produces, and enlarges the light irradiated area, increases the brightness and the definition of light.
To achieve the above object, the invention provides a kind of lighting device, comprising: a lampshade; One stacker, it is tubular, and this stacker is installed in this lampshade; One LGP, it is in order to mixed light, and this LGP is installed between this lampshade and this stacker; One reflecting layer, it is arranged between this lampshade and this LGP; And a plurality of substrates, it respectively has a light emitting diode, and these substrates are installed on this stacker.
Lighting device beneficial effect of the present invention is as follows: the present invention is installed between this lampshade and this stacker by this LGP, in order to mixed light, eliminates multiple little shadow that lumination of light emitting diode produces, and makes light source more clear; Be arranged between this lampshade and this LGP by this reflecting layer, make the light source of small size be expanded into large tracts of land, and then in this LGP, overlap and reach the effect of mixed light, make spot light change area source into through this reflective layer reflects.
For enabling further to understand feature of the present invention and technology contents, see also following relevant for detailed description of the present invention and accompanying drawing, yet appended accompanying drawing only for reference with the explanation usefulness, be not to be used for the present invention is limited.
