Abstract
The utility model discloses an LED lamp with a light source of a point-surface conversion structure. The LED lamp comprises a light source base, a light guide column and a light-transmitting lampshade. The LED light source is arranged on the bottom of the inner cavity of the light source base, the lower end of the light guide column is fixed to the top of the light source base and directly faces the LED light source, and the top end of the light guide column fixedly supports the light-transmitting lampshade. The side surface of the light guide column is provided with a frosted surface so that light emitted by the LED light source can be diffused through the frosted surface to form a light-emitting cylindrical surface. A reflection piece is arranged on the top of the light-transmitting lampshade and reflects the light propagated by the light guide column in the vertical direction into the light guide column, and therefore the utilization rate of the light energy of the lamp is increased.

Further, it also comprises a holder and a crossbeam LED lamp, and this holder is built-in with LED power supply driver; This crossbeam is hollow-core construction, and holder is fixed in its one end, on other end for described light source base is set; In crossbeam, be provided with the power line that connects LED power supply driver and LED light source.
Especially, described crossbeam is vertical with holder contact-making surface, and described light-guiding pillar is vertical with crossbeam, lampshade top respectively.
Further, the outer surface of described transparent lamp shade is provided with longitudinal stripe spaced apart.
Wherein, the back side, top of described transparent lamp shade is provided with a draw-in groove, and the top of described light-guiding pillar is inserted in this draw-in groove.
The beneficial effects of the utility model:
The utility model LED lamp is by being built in LED light source lamp body inside, and utilize the light-guiding pillar of optical grade PMMA material and the splendid smooth transport properties that lampshade has, the anaclasis that spot light LED is sent enters light-guiding pillar, and light-guiding pillar side surface frosting is set so that the light that reflects light-guiding pillar in this frosting generation diffuse reflection, light-guiding pillar is seemed as same Column being luminous, thereby realize the conversion of spot light and area source, in addition, the top of lampshade is provided with reflecting piece, in the light reflection meeting light-guiding pillar of vertical direction in light-guiding pillar, finally penetrate through light-guiding pillar side surface equally, improve the light source utilization rate of light fixture, in addition, in order to obtain light and dark illumination effect, lampshade outer surface is provided with longitudinal stripe, makes lampshade entirety uniformly light-emitting.
Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Fig. 1 is the installation diagram of the utility model LED lamp;
Fig. 2 is the cutaway view of the utility model LED lamp.
Detailed description of the invention
As shown in Figure 1 and Figure 2, for the LED lamp of a kind of light source point face transformational structure of the present utility model, the LED lamp of the present embodiment is only taking wall lamp as example, it comprises a holder 10, a crossbeam 20, a light source base 30, a light-guiding pillar 40, a transparent lamp shade 50, and this holder 10 is fixed on wall and it is built-in with LED power supply driver 60; This crossbeam 20 is hollow-core construction, and holder 10 is vertically fixed in its one end, on other end for described light source base 30 is set; The intracavity bottom of this light source base 30 is provided with LED light source 70, and the lower end of light-guiding pillar 40 is inserted in the top of light source base 30 and just to described LED light source 70, transparent lamp shade 50 described in the vertical fixed support in top of this light-guiding pillar 40; , in crossbeam 20, be provided with the power line (not shown) that connects LED power supply driver 60 and LED light source 70.
Thereby important improvement point of the present utility model is that the side of light-guiding pillar 40 is provided with frosting 100 forms luminous cylinder so that the light that LED light source 70 sends, through this frosting 100, diffuse reflection occurs, the top of described transparent lamp shade 50 is provided with reflecting piece 110, and the light emission that this reflecting piece 110 is propagated light-guiding pillar 40 vertical directions is returned in light-guiding pillar 40.
Concrete, the back side, top of described transparent lamp shade 50 is provided with a draw-in groove 80, and the top of described light-guiding pillar 40 is inserted in this draw-in groove 80 to realize being fixedly connected with of lampshade 50 and light-guiding pillar 40.
