The first side is provided with a protruding ring used for being combined on the LED recessed lamp, the part, inside the protruding ring, of the first side forms a first protruding cambered surface, and the first protruding cambered surface corresponds to an LED light source when mounted. The second side forms a second protruding cambered surface, the second protruding cambered surface is used for emitting light rays of the LED recessed lamp, and therefore the purpose of better dispersion effects and even light spots can be achieved.

Description

The optical lampshade of LED Recessed light

Technical field

The utility model, about the optical lampshade of a LED Recessed light, is espespecially applied in LED Recessed light to improve the optical lampshade structural improvement of its illuminating effect.

Background technology

Known LED Recessed light is the lighting apparatus for embedding ceiling, the LED light emitting module that it adopts comprises that a substrate and multiple array are encapsulated in the LED(light emitting diode on substrate), because LED has long service life and effect of power saving more, become gradually now the main flow of lighting apparatus.But, the light concentrations that LED light emitting module produces and have directionality, its dispersion effect is not good, and range of exposures and hot spot too concentrated, if be applied on room lighting, cannot reach preferably illuminating effect.For this reason, known LED lighting apparatus all can manage to install additional an optical module, the light sending in order to modulate LED light emitting module before light emitting module.But the light that how to make LED Recessed light send obtains better dispersion effect, enables Uniform Illumination, be the problem that the utility model will overcome.Moreover the lampshade of known LED Recessed light adopts glass to make more, if will use lower-cost plastics instead, will have influence on refraction and the transmission effects of light, be also that the utility model needs the problem solving in the lump.

Utility model content

The purpose of this utility model is to provide a kind of optical lampshade of LED Recessed light, and it is changed the light source of LED Recessed light, and then reached better dispersion effect and the uniform object of hot spot by the refraction improved structure of optical lampshade.

In order to achieve the above object, the utility model provides a kind of optical lampshade of LED Recessed light, and for being combined in a LED Recessed light, comprising an optical lens, it has one first side and contrary one second side; This first side has to be combined in a bulge loop of this LED Recessed light, and one first convex globoidal is formed on the shrinkage pool bottom of this first side in this bulge loop, the corresponding LED light source of this first convex globoidal; This second side forms one second convex globoidal, and this second convex globoidal projects the light of this LED light source.

The radian of this first convex globoidal and this second convex globoidal is π/4 ~ π/6.

Spacing between this first convex globoidal and the summit of this second convex globoidal is 1/7 ~ 1/9 of the first convex globoidal or the second convex globoidal radius of curvature dimensions.

The periphery of this bulge loop forms a plane of a loop, and the surrounding of this second convex globoidal is connected to the outer rim of this plane of a loop.

This bulge loop has the joint portion that is combined in this LED Recessed light.

This bulge loop is annulus.

This joint portion is the screw thread that protrudes this bulge loop outer ring surface.

Adopt after such scheme, the optical lampshade of the utility model LED Recessed light, utilize the screw thread of this bulge loop outer ring surface to be screwed on the body of LED Recessed light, LED Recessed light bottom surface is covered, and the corresponding LED light emitting module of the first convex globoidal that makes optical lens, make whereby the light of LED light emitting module construct by biconvex lens, out-of-focusly obtain better dispersion effect, and it is radiated at floor or body surface can obtain the more uniform effect of hot spot.

Detailed description of the invention

As Fig. 1, shown in Fig. 2 and Fig. 3, the optical lampshade of the utility model LED Recessed light, its preferred embodiment comprises that one in order to be combined in the optical lens 1 of LED Recessed light 2, this optical lens 1 is by transparent glass or integrally moulded or combination forming, it has one first side 11 and contrary one second side 12, wherein: as shown in Figures 3 to 5, this first side 11 has to be combined in a bulge loop 13 of LED Recessed light 2, one first convex globoidal 14 is formed on shrinkage pool 131 bottoms of this first side 11 in bulge loop 13, the first convex globoidal 14 preferably radian is π/4 ~ π/6, in the time that optical lens 1 is arranged on LED Recessed light 2, make the corresponding LED light emitting module 21 of the first convex globoidal 14, 12 of this second sides form one second convex globoidal 15, the second convex globoidal 15 preferably radian is π/4 ~ π/6, and the spacing d (thickness) between the second convex globoidal 15 and the first convex globoidal 14 summits is preferably 1/7 ~ 1/9 of the first convex globoidal 14 or the second convex globoidal 15 radius of curvature dimensions, best is 1/8, makes whereby the second convex globoidal 15 can project the light of LED light emitting module 21.

Again as shown in Figures 3 to 5, the peripheral plane of a loop 16 that forms of bulge loop 13 of this optical lens 1 of the utility model, and the surrounding of above-mentioned this second convex globoidal 15 is preferably connected to the outer rim of plane of a loop 16, so can utilize the edge (plane of a loop 16 parts) of optical lens 1 to shield whole LED Recessed light 2 (as shown in Figure 2), more attractive in appearance while making the installation of LED Recessed light.Moreover above-mentioned this bulge loop 13 is preferably annulus, its chosen place is provided with the joint portion 132 that is combined in LED Recessed light 2, preferably forms this joint portion 132 for being provided with screw thread at bulge loop 13 outer ring surfaces, therefore can utilize screw thread to be directly screwed on LED Recessed light 2.

Again as shown in Figures 1 and 2, housing 22 inner faces that the utility model can be selected LED Recessed light 2 are provided with two or two above holding sections 23, be preferably illustrated three holding sections 23, holding section 23 can be the salient point that punching press housing 22 forms, so make these bulge loop 13 outer ring surface screw-shaped joint portions 132 can be locked together in holding section 23, and also other structures of variable one-tenth of the joint portion 132 of this bulge loop 13, for example implement L shaped groove at bulge loop 13 outer ring surfaces, also can be combined in easily the holding section 23 of LED Recessed light 2.

As shown in Figure 6, when optical lampshade of the present utility model uses, be screwed on the holding section 23 of the housing 22 of LED Recessed light 2 by the joint portion 132 (screw thread) of bulge loop 13, make the corresponding LED light emitting module 21 of above-mentioned the first convex globoidal 14, and the second convex globoidal 15 and plane of a loop 16 parts can be got up whole LED Recessed light 2 shieldings.In the time that LED light emitting module 21 is luminous, its light can pass through the first convex globoidal 14 and second convex globoidal 15 twice refraction, therefore the part of light beyond focal distance f forms better scattering angle, overcome whereby the problem of range of exposures concentrations, promote the scope that LED Recessed light 2 irradiates, and its to be radiated at hot spot on floor or object more even.

In sum, the optical lampshade of the utility model LED Recessed light, really tool practicality and creativity, also for novelty undoubtedly, and effect and purpose of design really meet, and claimed rationally progressive to bright in the utilization of its technological means.
