Abstract
The utility model discloses a bulb shell for LED (light-emitting diode) lamps, which relates to a bulb shell, and particularly relates to a bulb shell for LED lamps. In an LED lamp on the current market, a light-pervious bulb shell with a uniform wall thickness is generally arranged on a light source, so that light emitted by the light source directly passes through the bulb shell and shines out, in such a way, a light-emitting surface is formed on the upside of the light source, and the light-emitting surface is small. The bulb shell disclosed by the utility model is characterized in that the top of the inner wall of the bulb shell is provided with a lens which is raised downwards, and the bulb shell and the lens are of an integral structure. Due to the bulb shell with a raised lens, part of light emitted by an LED light source directly shines out through the bulb shell, so that an illumination plane is formed on the upside of the light source, and the other part of light is reflected and refracted through the raised lens, so that an illumination plane is also formed on the underside of the light source, thereby achieving an effect that light is transmitted from a whole lamp body in all directions.
Description
Technical field
The utility model relates to a kind of cell-shell, espespecially the cell-shell of LED light fixture.
Background technology
LED light fixture in the market normally arranges the uniform printing opacity cell-shell of wall thickness at light source, and the light that light source sends directly sees through cell-shell and shines out, and in the upside formation light-emitting area of light source, light-emitting area is little.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, and provides a kind of cell-shell for the LED light fixture, to reach the purpose that increases light-emitting area.For this reason, the utility model is taked following technical scheme.
A kind of cell-shell for the LED light fixture is characterized in that: the lens to lower convexity are established at the inwall top of cell-shell, and described cell-shell and lens are the integral type structure.Cell-shell with protruding lens, the light part that led light source is sent directly sees through cell-shell and shines out, and at the upside formation plane of illumination of light source, a part is by reflection and the refraction of internal protrusion lens, thereby the downside at light source also forms plane of illumination, thereby reaches the comprehensive bright dipping of whole lamp body.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Little large under the described lens, arc transition between lens and the cell-shell.The light of led light source can be through the lens side and the arc-shaped transitional surface reflection.
Described lens are back taper.Taper can be taper shape or polygonal pyramid.
Described lens are reverse frustoconic.
Described lens outer surface is established the coating that increases reflecting effect.Coating can be located at lens side and or end face.
Cell-shell appearance shaft section is semicircle shape, or the semiellipse shape, or parabolic shape, or the upper end is that semicircle and lower end are the mushroom of rectangle, or upper end circular arc radius of curvature is less than lower end circular arc radius of curvature and middle pear shape by arc transition.
The wall thickness of described cell-shell is 0.1-2mm.
The lower end of cell-shell inside contracts and forms the lamp body connecting portion.The lamp body connecting portion is connected with the LED lamp body.The connecting portion that inside contracts can make it built-in, increases associative perception.
Beneficial effect: with the cell-shell of protruding lens, the light part that the led light source pedestal is sent directly sees through cell-shell and shines out, upside at light source forms plane of illumination, a part is by the internal protrusion lens, form reflection and refraction, thereby the downside at light source also forms plane of illumination, thereby reaches the omnibearing luminous of whole lamp body.The outer surface of projection lens can have coating to increase reflecting effect.
Description of drawings
Fig. 1 is the utility model sectional structure schematic diagram.
The 1-cell-shell; The 2-lens; The 3-connecting portion.
The specific embodiment
Below in conjunction with Figure of description the technical solution of the utility model is described in further detail.
Cell-shell 1 appearance shaft section is semicircle shape, or the semiellipse shape, or parabolic shape, or the upper end is that semicircle and lower end are the mushroom of rectangle, or upper end circular arc radius of curvature is less than lower end circular arc radius of curvature and middle pear shape by arc transition.The wall thickness of cell-shell 1 is 0.1-2mm.The inner cavity top of cell-shell 1 is established the lens 2 of projection, and described cell-shell 1 and lens 2 are the integral type structure.Cell-shell 1 with protruding lens 2, the light part that the led light source pedestal is sent directly sees through cell-shell 1 and shines out, upside at light source forms plane of illumination, a part is by internal protrusion lens 2, through reflection and refraction, thereby the downside at light source also forms plane of illumination, thereby reaches the omnibearing luminous of whole lamp body.Lens 2 times are little large, arc transition between lens 2 and the cell-shell 1.The light of led light source can be through lens 2 sides and the arc-shaped transitional surface reflection.Lens 2 are turbination, or fall polygonal pyramid or reverse frustoconic.In the present embodiment, described lens 2 are reverse frustoconic.The lower end of cell-shell 1 inside contracts and forms lamp body connecting portion 3, forms step surface between connecting portion 3 outer surfaces and cell-shell 1 outer surface.
For increasing reflecting effect, establish coating at the outer surface of protruding lens.
More than a kind of cell-shell for the LED light fixture shown in Figure 1 be specific embodiment of the utility model; the utility model substantive distinguishing features and progress have been embodied; can be according to the use needs of reality; under enlightenment of the present utility model; it is carried out the equivalent modifications of the aspects such as shape, structure, all at the row of the protection domain of this programme.
