Abstract
The utility model discloses an LED bulb, which comprises a lampshade, an LED lamp source, an LED driving assembly and a shell, wherein the lampshade is fixedly connected with the shell, the LED driving assembly is connected with and drives the LED light source, the LED light source is positioned in a cavity formed by connecting the lampshade and the shell, and the lampshade is shaped as a truncated cone. The LED bulb disclosed by the utility model has the advantages of reducing the dead angles of illumination of light, increasing the illumination angle of light emitted from the LED light source and improving the illumination brightness.
Description
Technical field
The utility model relates to the LED technical field, especially relates to a kind of LED bulb.
Background technology
Owing to have advantages such as long service life, energy-saving and environmental protection, LED has become a kind of preferable electrical lighting device and has been widely used in multiple occasion, and fluorescent lamp in the past, incandescent lamp are all replaced by the LED lamp gradually.Existing LED bulb generally comprises lampshade, led light source, LED driven unit and shell; Lampshade is fixedly connected with shell; The LED driven unit connects and the driving LED light source; Led light source is positioned at the cavity that lampshade and shell are connected to form, and the light of led light source emission is realized illumination through lampshade diffusion back.Existing lampshade generally all is a hemispherical, and the general emission angle of hemispheric lampshade can only be spent LED light diffusion 120, so that the irradiating angle of LED bulb is less, and the illumination dead angle is bigger, and brightness of illumination is less.
Summary of the invention
It is big that the utility model technical problem to be solved provides a kind of irradiating angle, the LED bulb that brightness of illumination is high.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of LED bulb; Comprise lampshade, led light source, LED driven unit and shell; Described lampshade is fixedly connected with described shell; Described LED driven unit connects and also drives described led light source, and described led light source is positioned at the cavity that described lampshade and described shell are connected to form, and described lampshade is a frustoconical.
The upper surface of described lampshade has been wholely set a frustum of a cone, and the bottom face of the described frustum of a cone overlaps with the upper surface of described lampshade fully.
Described lampshade bottom is provided with a plurality of buckles uniformly, and described shell is provided with a plurality of and described draw-in groove that is clasped, described lampshade and described shell clamping.
Described buckle quantity is 3
Compared with prior art; The advantage of the utility model is that lampshade is a frustoconical, and the light of led light source emission carries out multi-angle remission and refraction through the lampshade of frustoconical, has reduced the irradiate light dead angle; Increase the radiative irradiating angle of led light source, improved brightness of illumination;
When the upper surface of lampshade has been wholely set a frustum of a cone, when the bottom face of the frustum of a cone overlaps with the upper surface of lampshade fully, can with pass through light that lampshade launches further reflection disperse, strengthened the soft uniformity of light;
When lampshade bottom is provided with a plurality of buckles uniformly, shell is provided with a plurality of and draw-in groove that be clasped, and lampshade and shell clamping are easy for installation, time saving and energy saving;
When buckle quantity was 3,3 were fixedly connected between lampshade and the shell, and stability is strong.

Fig. 1 is the stereogram of the lampshade of the utility model;
Fig. 2 is the cutaway view of the lampshade of the utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one: as shown in the figure, a kind of LED bulb comprises lampshade 1, led light source, LED driven unit and shell; Lampshade is fixedly connected with shell; The LED driven unit connects and the driving LED light source, and led light source is positioned at the cavity that lampshade and shell are connected to form, and lampshade 1 is a frustoconical.
In the above-mentioned specific embodiment, the upper surface of lampshade 1 has been wholely set a frustum of a cone 2, and the bottom face of the frustum of a cone 2 overlaps with the upper surface of lampshade 1 fully.
In the above-mentioned specific embodiment, lampshade 1 bottom is provided with a plurality of buckles uniformly, and described shell is provided with a plurality of and draw-in groove that be clasped, lampshade and shell clamping, and wherein the quantity of buckle can be 3, lampshade 1 is through three buckles and shell secure fit.
In the above-mentioned specific embodiment, the diameter length of the upper surface of lampshade 1 is 0.85 with the ratio of the diameter length of the lower surface of lampshade 1.
In the above-mentioned specific embodiment, the light of led light source emission is through lampshade 1 diffusion, and the irradiating angle of LED bulb can reach 300 degree.
Embodiment two: present embodiment and embodiment one are basic identical, and its difference only is that the ratio of diameter length and the diameter length of the lower surface of lampshade 1 of the upper surface of lampshade 1 is 0.98.
Claims (4)
1. LED bulb; Comprise lampshade, led light source, LED driven unit and shell; Described lampshade is fixedly connected with described shell; Described LED driven unit connects and also drives described led light source, and described led light source is positioned at the cavity that described lampshade and described shell are connected to form, and it is characterized in that described lampshade is a frustoconical.
