Description
Technical field
The present invention relates to a kind of lighting, being specifically related to a kind of is the bulb of light source with light emitting diode (LED).
Background technology
At present, the light emitting source that indoor illumination light fitting adopted such as desk lamp is based on incandescent light bulb or fluorescent tube basically.And the electro-optical efficiency of incandescent light bulb or fluorescent tube is all lower, and its caloric value is big, and service life is shorter.
LED has advantages such as volume is little, caloric value is low, power consumption is low, the life-span is long as a kind of emerging light emitting semiconductor device, and therefore at present having occurred some on the market is the light fixture of light source with LED.Existing LED light fixture mostly is to form at the peripheral directly sheathed lampshade of the base of LED, not only influenced the light extraction efficiency of LED, and its radiating effect is not good yet, has influenced the service life of light fixture greatly.
Summary of the invention
The object of the invention provides a kind of LED bulb with radiator structure, makes it have long service life.
For achieving the above object, the technical solution used in the present invention is: a kind of LED bulb, comprise LED, base and be provided with lampshade on the base, be provided with speculum in the described lampshade, the inboard of speculum is provided with one deck heat radiation shell, fixedly connected with base in the bottom of heat radiation shell, its top is provided with opening, forms heat dissipation channel;
Described LED is at least 2, and by heat sink be fixed in the heat radiation shell the bottom, LED circumferentially is distributed between described lampshade and the speculum;
The lower sides of described base is provided with at least 1 ventilating opening, and ventilating opening is communicated with described heat dissipation channel.
Above, described speculum can be the speculum cover, and its top is connected with lampshade, its bottom is located on the heat radiation shell, between lampshade and the speculum LED is set, thereby the light that LED sends can the overwhelming majority penetrate by lampshade, reduce the light loss consumption, improved illumination brightness.Simultaneously, be provided with one deck heat radiation shell in the inboard of speculum, form heat dissipation channel, and the lower sides of base be provided with ventilating opening, cold wind can enter from this ventilating opening, discharges from the open top of heat radiation shell, thereby takes away the interior heat of LED bulb, plays the effect of heat radiation.Because the heat in the bulb is mainly produced by LED, thus in the LED bottom heat sink is set, and heat sink is fixed on the heat radiation shell bottom, thereby heat is shed smoothly.
Can be fixing between described speculum and the heat radiation shell with the heat-conducting glue bonding, also can loose and remove a part of heat.
The quantity of described LED is set according to the size and the actual conditions of bulb, optimized technical scheme, and described LED is 4, and circumferential uniform setting.LED is circumferentially uniform, and that the distribution that can make irradiates light is set is comparatively even.
In the technique scheme, described ventilating opening is 4, circumferentially is distributed on the base side wall.
In the technique scheme, also be provided with power module in the described base, power module is electrically connected with LED.
In the technique scheme, the bottom of described base is provided with metal spiral shell tail.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the present invention is provided with the heat radiation shell in the inboard of speculum, form heat dissipation channel, ventilating opening is set on base side wall again, thereby, cold wind can enter from this ventilating opening, discharges from the open top of heat radiation shell, thereby takes away the interior heat of LED bulb, play the effect of heat radiation, thereby improved the service life of bulb.
2, because the heat in the bulb is mainly produced by LED, so heat sink is set, and heat sink is located at heat radiation shell bottom, thereby heat is shed smoothly in the LED bottom; In addition, can be fixing between speculum and the heat radiation shell with the heat-conducting glue bonding, also can loose and remove a part of heat, play certain thermolysis.
3, the present invention is provided with speculum in lampshade, and LED is located between lampshade and the speculum, thereby when LED is luminous, part direct projection light directly is refracted to the outside by lampshade, another part direct projection light reflects, and reflection ray is just in time beaten the surface at speculum, by speculum secondary reflection and penetrating by lampshade again, thereby reduced the light loss consumption greatly, improved illumination brightness.
4, the present invention is simple in structure, is easy to make, and production cost is also lower simultaneously, is fit to apply.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment one
Shown in Fig. 1～3, a kind of LED bulb comprises LED4, base 7 and is provided with lampshade 1 on the base, be provided with speculum 2 in the described lampshade 1, the inboard of speculum is provided with one deck heat radiation shell 3, fixedlys connected with base in the bottom of heat radiation shell, its top is provided with opening, forms heat dissipation channel;
Described LED is 4, and by heat sink 5 be fixed in the heat radiation shell the bottom, LED circumferentially is distributed between described lampshade and the speculum;
