The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described further.Following examples are only for the utility model is described, but are not used for limiting scope of the present utility model.

The lighting provided in the present embodiment is Lawn lamp as shown in Figure 1, and this Lawn lamp mainly comprises the assemblies such as bonnet 1, reflector plate 2, LGP 4, light-emitting component 8, annular lamp bracket 3, diffusion sheet 5, Transparent lamp shade 6 and lamppost 7.Airtight space of bonnet 1 and the involutory formation of Transparent lamp shade 6, and by component package such as reflector plate 2, LGP 4, light-emitting component 8, annular lamp bracket 3 and diffusion sheets 5 in the space airtight at this, lamppost 7 passes from the center of Transparent lamp shade 6, diffusion sheet 5, annular lamp bracket 3, LGP 4 and reflector plate 2, and is fixedly connected with bonnet 1.LGP can, for circle, square, polygon etc., not done particular determination at this; Offer the aperture that holds light-emitting component 8 at the center of LGP 4, the incidence surface that the periphery of aperture is LGP 4; The exiting surface that the one side of LGP 4 is LGP, the bottom surface that the another side relative with this exiting surface is LGP.LGP 4 is to utilize ejection formation or other any known methods that acrylic material is pressed into to ganoid plate, then utilize high reflectance and not the material of extinction form the leaded light site of required pattern in the acryl planar bottom surface, when light incides the leaded light site, by site, reflected, can disperse to all angles, then penetrated by the exiting surface of LGP 4, utilize various density, leaded light site not of uniform size, can make the uniform light of LGP 4 outgoing; The bottom surface of LGP 4 is pasted with reflector plate 2 usually, for the light reflection that will go out from the bottom surface loss, returns LGP 4, takes full advantage of luminous energy, thereby has improved the optics utilization rate; Several light-emitting components of arranging in the form of a ring 8 are positioned at the center of LGP 4, by center light inlet technology, the light that light-emitting component 8 sends is coupled into LGP 4 uniformly from all directions, thereby make from the planar light of LGP 4 outgoing softer, even, for people provide comfortable photoenvironment; And facilitate the installation of lamppost.In addition, prior art comprises the Lawn lamp of LGP, and due to the existence of lamppost, the zone that the light of LGP outgoing is corresponding at lamppost can't provide illumination, and luminous energy can not be fully utilized and cause the waste of the energy; And in the utility model, owing to being the center that light-emitting component 8 is arranged in LGP 4 in the form of a ring, from inside to outside provide light to LGP 4, do not provide illumination fully in the zone of lamppost 7 correspondences, fundamentally avoid the waste of luminous energy, therefore promoted to a certain extent the optics utilization rate.

As shown in Figure 1 and Figure 2, LGP 4 centers are provided with annular lamp bracket 3, and light-emitting component 8 is fixed on the circumference of annular lamp bracket 3.Annular lamp bracket 3 can play the effect of location and supporting light-emitting component 8 on the one hand, can avoid on the other hand light-emitting component 8 to contact with the direct of lamppost 7, and protection light-emitting component 8 does not sustain damage.More even for the illumination that makes to provide, light-emitting component 8 is evenly distributed on the circumference of annular lamp bracket 3, for example, is uniformly distributed with 12 light-emitting components on the circumference of annular lamp bracket 3; And evenly rational spacing is conducive to the heat radiation of light-emitting component, improve the service life of light-emitting component.

In order to coordinate the light-emitting component 8 on the above-mentioned circumference that is evenly distributed on annular lamp bracket 3, the position of the corresponding light-emitting component 8 in the leaded light site on LGP 4 and the printing treatment that angular distribution is done rule, form position and the distributing position of density and light-emitting component 8 and the leaded light site of angular distribution adaptation, the light incided in LGP 4 is dispersed fully, thereby reached the optimum uniformity.

Simultaneously, in the present embodiment also the surrounding lateral edges at LGP 4 attached reflector plate, carry out the light leakage processing, make the light of not outgoing be returned to effective outgoing zone secondary utilization, further promote the utilization rate of luminous energy.

In the present embodiment, at the exiting surface of LGP 4, also be provided with diffusion sheet 5; Diffusion sheet 5 mainly comprises the diffusion layer that the base material of high printing opacity light rate and the many scattering particles in being dispersed in base material form, light can be constantly when the diffusion layer passing in different medium two refractive indexes, meanwhile, the phenomenon of many refractions, reflection and scattering will occur in light, has so just caused the effect of optics diffusion; By diffusion sheet 5 being set by the planar light atomization of LGP 4 outgoing, make soft the shining in surrounding environment of light in the present embodiment, thereby play good night illumination effect, and can not destroy the harmony of nighttime landscape.

Wherein, above-mentioned light-emitting component 8 is preferably the LED lamp; The LED light fixture has the light quality high, essentially no radiation, and the advantage such as reliability and durability, optical efficiency is high, and caloric value is low, and maintenance cost is very cheap, can significantly reduce the use cost of lighting.Certainly, above-mentioned light-emitting component 8 can be also CCFL(Cold Cathode Fluorescent Lamp, CCFL) or fluorescent tube etc.

Bonnet 1, also has protection lighting intraware and is not subject to the effect of extraneous interference, thereby increased the service life of lighting with Transparent lamp shade 6 except encapsulation effect; Wherein, Transparent lamp shade 6 materials are preferably transparent PC(Polycarbonate, Merlon) material, polycarbonate plate has good light transmission, impact resistance, and is easy to processing and forming.

The conducting terminal of light-emitting component 8 need to connect power supply unit by wire 10, therefore, also on lamppost 7, has reserved the metallic channel 9 of accommodating this wire in the present embodiment, facilitates the fixing and protection of wire 10, concrete as shown in Fig. 3 and Fig. 4.

The height of lamppost 7 can specifically arrange according to peripheral environment, so that the effective integration of realization and surrounding environment; By optimum lamppost 7 height is set, not only risen and can arrive illuminating effect but also not affect environmental degree of comfort.

Lighting provided by the utility model is to be not limited to Lawn lamp cited in the present embodiment, can be also street lamp, pavement and garden lamp etc.

Above embodiment is only for illustrating the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that do not break away from spirit and scope of the present utility model; can also make a variety of changes and modification, therefore all technical schemes that are equal to also belong to protection category of the present utility model.
