Abstract

The utility model relates to a no dizzy field effect bulb, which comprises a glass casing, a bulb seat, and a filament. The utility model is characterized in that the surface of the glass casing is provided with a filter layer which is composed of a plurality of miniature convex lenses. The utility model has advantages that the glare of an illumination lamp is eliminated, the main light with an effective range is reserved, the bright field effect light is also reserved, and the front periphery of the illumination lamp is illuminated. The utility model can be widely used for head lamps of various vehicles, the utility model is suitable for human eyes, and the drive is safe. The utility model is especially suitable for replacing the incandescent bulb which is widely used at present, and meanwhile, the utility model is suitable for various other illumination lamps.

Description

A kind of no dizzy field effect bulb

The utility model belongs to the lighting bulb of a kind of lighting, particularly a kind of free from glare.

The domestic and international at present higher bulb of transparency that uses, all there is dazzle in various degree, people's eyes can not be looked at straight, the headlamp of automobile for example, the one, night illumination rolling eyes, increase the driving at night unsafe factor, the 2nd, adopt the meeting device for changing light, moment makes the people produce the physiological vision blind area by the high light light that dies down, literally in the dark dark, be easy to take place traffic accident; Also there is the dazzling problem of dazzle in the illuminating lamp of locating for some venues etc.

The purpose of this utility model provides a kind of novel lighting bulb, eliminate dazzle, keep the key light of effective range, bring great convenience to use, especially solve the problem that automotive headlight dazzles, provide a kind of safe lighting device for avoiding driving at night that traffic accident easily takes place.

The purpose of this utility model is achieved in that it comprises glass housing, lamp socket and filament, and its technical scheme main points are: the filter layer that is made of many miniature convex lens is laid in the glass shell surface.

Because many miniature convex lens are laid in the glass shell surface, make original monomer optics original paper become the combination of numerous optics original papers, miniature convex lens have been formed the net battle array of the miniature convex lens of one deck, when making light beam behind the light source optically focused penetrate the net battle array, become the combined beam light of numerous light, thereby eliminated most of dazzle.With regard to monomer dimpling lens, its central main shaft sees through effective lighting light, reaches the purpose of effective range, and the incident ray of other angle is the dazzle source, forms the field effect illumination light through the diffusion of dimpling lens curved surface, has finally finished the purpose of eliminating dazzle.

Through the light that the filter layer of being made up of numerous dimpling lens penetrates, both kept the key light of effective range, bright field effect light is arranged again, illuminated illuminating lamp the place ahead and on every side, eliminated again and shaken the dazzle of human eye.

The utility model has the advantages that: solved the problem that various bulb dazzles are dazzled, especially eliminated the dazzle of motor vehicle illuminating lamp, the key light that had both kept effective range, bright field effect light is arranged again, illuminate illuminating lamp the place ahead around, be widely used in the headlamp bulb of various vehicles, adapt to human eye, traffic safety also is applicable to other various lighting bulbs simultaneously.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the local enlarged diagram of the glass housing of Fig. 1.

See Fig. 1,2, concrete structure is as follows: the filter layer that the inner surface of transparent glass housing 1 or outer surface bonding one deck are made of many miniature convex lens 2.The cross sectional shape of miniature convex lens 2 can be ellipse or sphere, and diameter is 0.1-2.5mm, and laying quantity is 100-1000/square centimeter.The shape of bulb is because different purposes is designed to difformity.

The utility model the experiment proved that, illuminance meets national standard, it removes and is applicable to various vehicle head lamps, also particularly suitable also substitutes present widely used incandescent lamp bulb, also be applicable to that simultaneously airport, harbour, gymnasium, field, shop etc. locate illuminating lamp, and mine lamp, military with lamp and the guarantor of family order desk lamp etc.

Claims

1, a kind of no dizzy field effect bulb, it comprises glass housing, lamp socket and filament, it is characterized in that: the filter layer that is made of many miniature convex lens is laid in the glass shell surface.
