Description

A kind of LED fitting structure that has scattering and direct projection effect concurrently

Technical field

The utility model relates to a kind of fitting structure, relates in particular to a kind of LED fitting structure that has scattering and direct projection effect concurrently.

Background technology

LED (light emitting diode) since coming out, each side's concern.Because LED has every advantages such as power saving, volume is little, efficient is high, plasticity is big, be there's no one who doesn't or isn't to be devoted to utilize LED with present all kinds of industries, make the more power saving of product, more efficient of self.The science and technology of LED was significantly progressive in recent years, made the brightness raising of LED, cost reduce, and was also ripe gradually as the technology of main lighting apparatus with LED.Add that energy starved threatens the influence with Global Greenhouse Effect,, more power saving brighter than fluorescent tube, more energy-conservation LED certainly will become the illumination trend of a new generation.

Yet though LED unit brightness height, the light that it sent has directive property, so the light that existing LED bulb sends is also inhomogeneous and scope is narrow.With regard to room lighting, the LED bulb of prior art is unsatisfactory, though for example being installed in the LED bulb of ceiling can illuminate the zone of bulb below, but be positioned at the part around ceiling corner or the bulb, but obviously feel dim, extremely undesirable for indoor light source, make existing LED bulb still can't replace conventional lamp, be unfortunate very.

Summary of the invention

Main purpose of the present utility model is to provide a kind of LED fitting structure that has scattering and direct projection effect concurrently, and the light that the LED bulb can be sent carries out scattering and direct projection simultaneously, makes it be able to even illumination, enlarges the light covering scope simultaneously.

For reaching above-mentioned purpose, the utility model provides a kind of LED fitting structure that has scattering and direct projection effect concurrently, and it mainly comprises:

Light-emitting component is the LED bulb structure;

Light conductor is arranged at described light-emitting component front end, is provided with loophole, and described loophole is right against described light-emitting component.

The utility model also provides a kind of LED fitting structure that has scattering and direct projection effect concurrently, and it mainly comprises:

Light-emitting component is the LED bulb structure;

Light conductor is arranged at described light-emitting component front end, is provided with the clear area of transparent entity structure, and described clear area is right against described light-emitting component, and the light conductor except that the clear area is an opaque shape or translucent.

Compared with prior art, the LED fitting structure that has scattering and direct projection effect concurrently described in the utility model includes parts such as body, light-emitting component and light conductor; Wherein body is main pedestal and can be connected to light fixture, and light-emitting component is arranged at body as main light source, before light conductor then is arranged at light-emitting component.The light that light-emitting component produced is directly injected in the light conductor, and light goes out through light conductor diffusion refraction, and then produces even brightness light, enlarges the scope of described light irradiation simultaneously.And then allow the LED bulb replace conventional light source such as fluorescent tube, incandescent lamp bulb etc., and become the main flow of room lighting, reach power saving, environmental protection, effect such as energy-conservation.

Described light conductor is provided with loophole before being positioned at light-emitting component, and sharp light source can directly pass, and is not stopped and the brightness that decays, to obtain desirable bright illumination.

Described light conductor includes suitable cloudy surface or translucent structure, and behind the light source process cloudy surface or translucent structure that light-emitting component produced, effectively scattering manifests diffusion and uniform illumination.

The specific embodiment

Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.

Head sees also Fig. 1 and shown in Figure 2, and the LED fitting structure that has scattering and direct projection effect concurrently described in the utility model mainly is made up of body 1, heat abstractor 2, light-emitting component 3 and light conductor 4.Wherein body 1 is main pedestal, and have binding end can be in conjunction with miscellaneous part.Heat abstractor 2 comprises fin 21 and fan 22, and described fin 21 is incorporated into binding end 11, and fan 22 then is combined between body 1 and the fin 21.3 of light-emitting components comprise plural LED, and described light-emitting component 3 is to be arranged at fin 21 lateral surfaces.As for light conductor 4, be a transparent or semitransparent plate, appropriate location offers loophole 41, and loophole 41 is right against light-emitting component 3, must include the transparent body 42 in the light conductor 4, and translucent body 43, and it is vaporific that described translucent body 43 also can be the surface.Described light conductor 4 rims slightly are bending, and light conductor 4 can utilize screw to be combined on the heat abstractor 2.

Then see also Fig. 3, when light-emitting component 3 was luminous, partly the light of direct projection outwards passed through light conductor 4 by loophole 41 earlier, the light source of all the other part light-emitting components 3 then enters light conductor 4, after passing through the transparent body 42 and translucent body 43, light source is spread, and last scattering outwards goes out.So, this case light source has direct projection and dispersion effect concurrently, and is quite desirable.

The utility model realistic application conditions can be consulted Fig. 1 and shown in Figure 4, is mounted to lamp socket 5 to screw togather end 12, is provided with suitable electric power and can produces light.

This case characteristics are the setting of translucent body 43 in the mat light conductor 4, allow light-emitting component 3 produce even and large-scale light source dispersion effect, and then make the LED bulb be become main room lighting light source.

The light conductor 4 of this case except that having scattering function, has the fixedly effect of clamping light-emitting component 3 concurrently.Because light-emitting component 3 is located in 2 of light conductor 4 and heat abstractors, so the thermal source of light-emitting component 3 is easy to and can transmits heat radiation by the heat abstractor of being close to it 2.

Light conductor 4 structures of this case get according to need variation arbitrarily.For example the transparent body 42 and translucent body 43 positions are exchanged, or translucent body 43 only is set and is not provided with the transparent body 42, or be to mingle the position that changes the transparent body 42 and translucent body 43, be all the category that this case can be implemented and protect.

The loophole 41 of this case light conductor 4 can change with clear area 49 and implement.As Fig. 5 and Fig. 6, described light conductor 4 is arranged to the clear area 49 of transparence in light-emitting component 3 corresponding positions, so, identically allows the light source direct projection of light-emitting component 3 pass.

More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
