Abstract
The utility model belongs to the technical field of daily necessities, in particular to a lamp. The lamp comprises a lamp holder, a radiator and a light source, wherein a light expansion shade used for covering the light source is connected to the radiator; the light expansion shade is subjected to integrated molding; the beam angle of the light source is greater than or equal to 270 degrees; the light expansion shade is integrally formed, and the cost is low. The light expansion shade is of a sealed cylinder shape; one end of the light expansion shade covers the light source; the other end of the light expansion shade is sealed, and the end face is inwards concave; light rays which are emitted by the light source are subjected to transmission, reflection and refraction of the tube wall of a cylinder and the inwards concave surface, so the beam angle of the light source is greater than or equal to 270 degrees, which is approximate to the beam angle of the traditional osram lamp. The lamp has the characteristics that the beam angle is large, the production cost is low and the service life is long.
Description
Technical field
The utility model relates to one way of life articles for use, relates in particular to a kind of light fixture.
Background technology
Along with the progressively raising of people's living standard, to lamp luminescence utilization, be no longer single light illumination mode, under the different sights of different occasions, need decorative effect, the illumination of supermarket vegetables and fruits, patient in hospital etc. all have different demands to light.LED, because the features such as environmental protection, energy-conservation, life-span be long are widely used in present light fixture, replaces conventional incandescent.Because LED has directive property, the LED ball of electricity-saving lamp bubble is can only be forward luminous and can not be luminous backward, has caused the rising angle of the LED ball bubble on existing market to be all less than 180 degree.Like this, when lighting environment needs Multi-azimuth luminous, this LED ball bubble just can not get application.
Utility model content
For the little problem of existing light fixture rising angle, the technical problem that the utility model solves is to provide the light fixture that a kind of rising angle is large.
The technical problem that the utility model need solve is achieved through the following technical solutions: a kind of light fixture, comprise lamp holder, radiator and light source, on radiator, be connected with the expansion light shield that covers light source, described expansion light shield is integrally formed, and the rising angle that makes light source is more than or equal to 270 degree, light shield is integrally formed, and cost is low.Described expansion light shield is the cylindric of closed, and one end covers light source, and other end Closed End is inner concave, and the light that light source sends, through transmission, reflection and the refraction of cylinder tube wall and inner concave, makes the rising angle of light source be more than or equal to 270 degree.
Further: in above-mentioned light fixture, the longitudinal section line that expands light shield Closed End is curved, makes the rising angle in source reach as far as possible omnibearing.The longitudinal section line that most preferably expands light shield Closed End is circular arc line.Described circular arc line is to be intersected and formed by two sections of circular arc lines, and design is succinct, easily processing.The light reflection that the inner concave of two sections of arc surface formation is dispersed out by LED goes back, and to improve the drawback that LED lighting angle is little, increases the lighting angle of LED light fixture, makes brightness excess smoothness in overall space of light fixture, there will not be obvious comparison of light and shade.Described expansion light shield is provided with frosting, makes light soft, and Jian Shao Shi-hyun light.Described light source is LED light source, power saving, and the long service life of light fixture.Described expansion light shield is connected on radiator by snapping or bonding mode.Expand light shield and radiator and be fixed together by button bit or the auxiliary mode of glue, LED light source is screwed and is arranged on radiator, and covers with expansion light shield.The periphery of described radiator is also provided with snap ring, and decorative lampshade is installed on snap ring, and decorative lampshade can be replaced arbitrarily, tears open, fills all very convenient.Radiator bottom is provided with internal thread, for being connected with other lamp decoration fittings, so the assembling of whole light fixture easily.
Compared with prior art, it is integrally formed that light fixture of the present invention expands light shield, and make the rising angle of light source be more than or equal to 270 degree, and light shield is integrally formed, and cost is low.Described expansion light shield is the cylindric of closed, and one end covers light source, and other end Closed End is inner concave, guarantees that light that light source sends, through transmission, reflection and the refraction of cylinder tube wall and inner concave, makes the rising angle of light source be more than or equal to 270 degree.
And the present invention is very extensive to the type requirements of LED light source, so long as the LED in the scope that expands the permission of light shield size all can be used this invention.And this invention can be mated existing lamp decoration product very easily, making traditional lamp ornaments lighting industry can be LED illuminating product by traditional lamp decoration production interchange very easily.So rising angle of the present utility model is large, production cost is low, long service life, applied widely.

The specific embodiment
With reference to accompanying drawing 1,2 and the specific embodiment, carry out comparative illustration the utility model.
Embodiment one: as Fig. 1,2, a kind of light fixture, comprises lamp holder 1, radiator 2 and light source 3, is connected with the expansion light shield 4 that covers light source on radiator 2, and described expansion light shield is integrally formed, and makes the rising angle of light source be more than or equal to 270 degree.Described expansion light shield 3 is semi-enclosed cylindric, and the Closed End that expands light shield is inner concave 41.The middle section line that expands light shield Closed End is circular arc line.Described circular arc line is two sections of circular arc lines that curvature is not identical.Described expansion light shield 4 is provided with frosting.
Embodiment two: as Fig. 3,4, on the basis of embodiment one, described expansion light shield 4 is connected on radiator 2 by snapping or bonding mode.Expand light shield 4 and radiator 2 and be fixed together by button bit or the auxiliary mode of glue, LED light source 3 is screwed and is arranged on radiator 2, and covers with expanding light shield 4.The periphery of described radiator 2 is also provided with snap ring 5, and decorative lampshade 6 is installed on snap ring 5, and decorative lampshade 6 can be replaced arbitrarily, tears open, fills all very convenient.Radiator 2 bottoms are provided with internal thread, for being connected with other lamp decoration fittings, so the assembling of whole light fixture easily.
Under above-mentioned two kinds of embodiments, described light source is LED light source.Expand light shield 4 integrally formed, production cost is low.Described expansion light shield 3 is the cylindric of closed, and one end covers light source, and other end Closed End is inner concave 41, guarantees that light that light source sends, through transmission, reflection and the refraction of cylinder tube wall and inner concave, makes the rising angle of light source be more than or equal to 270 degree.Described light source is LED light source, long service life.So light fixture of the present utility model has, rising angle is large, production cost is low, the feature of long service life.
The above is preferred embodiment of the present utility model, is not departing from the utility model design situation, carries out any apparent distortion and replacement, all belongs to the utility model protection domain.
