Abstract

The utility model discloses an LED lighting bulb which comprises a casing and LED luminous tubes, wherein the LED luminous tubes are arranged on a lamp holder which is arranged at the bottom of the casing, the inner side wall of the casing is provided with at least two light reflecting arrises, the light reflecting arrises are symmetrically arranged along the periphery of the casing and the outer side wall of the casing is uniformly distributed with prismatic stripes. The inner side wall of the casing is in a cylinder shape, the number of the light reflecting arrises is three, the light reflecting arrises are arranged in the direction of the generating line of the inner side wall of the casing and the prismatic stripes are arranged in the direction of the generating line of the outer side wall of the casing. The utility model is provided with three LED luminous tubes which are respectively arranged facing the three light reflecting arrises. The LED lighting bulb has the advantages of simple structure, small size, low power consumption, rich color and good decorative property and can be widely used for lighting and decoration in families and public places.

Description

The LED lighting bulb

Technical field

The utility model relates to a kind of lighting, relates in particular to a kind of LED lighting bulb.

Background technology

Existing illuminating lamp adopts incandescent lamp and fluorescent lamp usually, and the incandescent lamp consumed power is bigger, and the life-span is short, and fluorescent lamp generally need dispose ballast, and volume is bigger, and its color is single, and is ornamental relatively poor.

The utility model content

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, and volume is little, consumed power is few, the LED illuminating lamp of rich color, good decorative property.

For achieving the above object, the technical solution of the utility model is: a kind of LED lighting bulb, comprise housing, it is characterized in that: comprise the LED luminous tube, the LED luminous tube is arranged on the lamp socket of housing bottom, be provided with at least two reflection edges at the housing madial wall, reflection edge is symmetrical arranged along the housing periphery, and at the hull outside wall prismatic striped that evenly distributes.

Because adopt the LED luminous tube as illuminator, its volume is little, power consumption is little; The LED luminous tube that is equipped with different colours can produce different color, its rich color; The reflection edge that is provided with at the housing madial wall can transmission and refracted ray, make the LED illuminating lamp produce omnibearing radiation response, produce the illuminating effect close with the general lighting lamp, then can further reflect illuminating ray at the equally distributed prismatic striped of hull outside wall, light is dazzled in generation, can produce good illuminating effect and decorative effect.

Described housing madial wall can be tubular, be convenient to the housing injection moulding and the demoulding, described reflection edge can be three, be provided with along housing madial wall generatrix direction, and described prismatic striped is along the generatrix direction setting of hull outside wall, and reflection edge and prismatic striped all are provided with along the housing generatrix direction can strengthen illuminating effect and decorative effect.

Described LED luminous tube is three, towards three reflection edges, makes illuminating effect better respectively.

The cross sectional shape of described reflection edge can be trapezoidal, triangle or arc, and the cross sectional shape of described prismatic striped can be triangle.

Description of drawings

Fig. 1 is the outside drawing that the utlity model has the LED illuminating lamp housing of three reflection edges.

Fig. 2 is Figure 1A-A cutaway view.

Fig. 3 is Fig. 1 upward view.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, LED lighting bulb of the present utility model, comprise housing 1, it is characterized in that: also comprise the LED luminous tube, the LED luminous tube is arranged on the lamp socket of housing 1 bottom, be provided with at least two reflection edges 2 at the housing madial wall, reflection edge 2 is symmetrical arranged along housing 1 periphery, and at the housing 1 lateral wall prismatic striped 3 that evenly distributes.

As shown in Figure 2, described housing 1 madial wall can be tubular, and described reflection edge 2 can be three, is provided with along housing 1 madial wall generatrix direction, and described prismatic striped 3 then can be along the generatrix direction setting of hull outside wall.Described LED luminous tube is three, respectively towards three reflection edges.The cross sectional shape of described reflection edge 2 can be trapezoidal, triangle or arc.The cross sectional shape of described prismatic striped 3 is a triangle.

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment the protection domain that all any improvement that the utility model is done or modification all belong to the utility model claim.
