Description

A kind of LED fluorescent lamp of large lighting angle

Technical field

The utility model relates to the LED field of illumination lamp technology, particularly relate to a kind of LED fluorescent lamp of large lighting angle.

Background technology

Under the background raise once again in Present Global energy starved worry, save the energy and be our the current major issue faced.With conventional light source, compare, light emitting diode (LED) has the advantages such as higher luminous efficiency, low radiation, low power consumption, life-span length, low driving voltage, startup are quick, environmental protection, antidetonation resistance to compression, light fixture Miniaturizable, can operate a series of application of various indications, demonstration, general lighting etc.In prior art, the lighting angle of common LED fluorescent lamp is mostly 120 °, and the ambilateral dark space of lamp is larger, like this for some occasions, just can't meet people's user demand.In addition, general lampshade all has reflection function, and iff the light scattering that just increases lampshade, and the lamp luminescence angle is inadequate, and light so out is just even not.

Therefore, for above-mentioned situation, design simple in structurely, lighting angle is large, and long service life goes out the LED fluorescent lamp of the large and a kind of large lighting angle that outgoing light homogeneity is good of luminous intensity, just inventor's problem to be solved.

Summary of the invention

The technical problem that the utility model mainly solves is to provide a kind of LED fluorescent lamp of large lighting angle, can strengthen lighting angle, improves scattering efficiency, strengthens and luminous intensity and outgoing light homogeneity.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the LED fluorescent lamp that a kind of large lighting angle is provided, comprise that cross section is the lampshade of circular arc and the lamp socket that cross section is circular arc, described lampshade lower surface is provided with corrugated projection, described lampshade and lamp socket are cylindrical after fastening, the inner accommodation space that forms after described lampshade and lamp socket fasten, be provided with between two parties the aluminium base draw-in groove in described accommodation space, described aluminium base draw-in groove is embedded in the aluminium base of bar shaped, be provided with between two parties luminescence component on described aluminium base, described aluminium base draw-in groove two ends are connected with and are the heat radiation aluminum component that splayed arranges, the downside of described heat radiation aluminum component is provided with the lampshade draw-in groove, described lampshade inwall is provided with overhead kick, described overhead kick is embedded into the lampshade draw-in groove, the radian of described lampshade is greater than the radian of lamp socket.

In preferred embodiment of the utility model, described aluminium base draw-in groove and heat radiation aluminum component are connected as a single entity structure; The top layer of described heat radiation aluminum component is coated with high scattered power diffuse reflection nano material.

The beneficial effects of the utility model are:

1, the light that the utility model luminescence component sends sees through the wavy bulge on lampshade, light is fully reflected and diffusion, simultaneously, the light after refraction, by the scattering of heat radiation aluminum component, makes lighting angle reach 240 °, so greatly improved the efficiency of scattering, increase the rising angle of light, also reduced lighting dead angle, in addition, what also strengthened lampshade goes out luminous intensity and the uniformity, makes its light emission rate reach 94% left and right;

2, the radian of the utility model lampshade is greater than the radian of lamp socket, makes the illumination effect of whole LED fluorescent lamp better, and in addition, the utility model is reasonable in design, simple in structure, saves the energy and cost low, is convenient to batch production.

The accompanying drawing explanation

Fig. 1 is perspective view of the present utility model;

In accompanying drawing, the mark of each parts is as follows: 1, lampshade 2, projection 3, lampshade draw-in groove 4, lamp socket 5, aluminium base draw-in groove 6, heat radiation aluminum component 7, aluminium base 8, luminescence component.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1, the utility model embodiment comprises: cross section is the lampshade 1 of circular arc and the lamp socket 4 that cross section is circular arc, described lampshade 1 lower surface is provided with corrugated protruding 2, described lampshade 1 is cylindrical after fastening with lamp socket 4, the inner accommodation space that forms after described lampshade 1 fastens with lamp socket 4, be provided with between two parties aluminium base draw-in groove 5 in described accommodation space, described aluminium base draw-in groove 5 is embedded in the aluminium base 7 of bar shaped, be provided with between two parties luminescence component 8 on described aluminium base 7, described aluminium base draw-in groove 5 two ends are connected with and are the heat radiation aluminum component 6 that splayed arranges, the downside of described heat radiation aluminum component 6 is provided with lampshade draw-in groove 3, described lampshade 1 inwall is provided with overhead kick, described overhead kick is embedded into lampshade draw-in groove 3, the radian of described lampshade 1 is greater than the radian of lamp socket 4.
