Description
Technical field
What the present invention relates to is light fixture, especially a kind of LED bulb.
Background technology
The common power consumption of conventional incandescent is big, and the temperature height, is unfavorable for energy-conservation.Along with the development of LED technology, it is found that LED is one of at present best lighting source, it has advantages such as luminosity height, long service life.But the temperature during the led light source operation is higher, for improving LED running environment, all can utilize radiator to distribute the operating heat of LED for the higher led light source configuration radiator of running temperature usually.Existing is that the illuminating lamp of light source is a kind of LED bulb of direct irradiation structure with LED, and it is roughly the same that the structure of this LED bulb and ordinary incandescent lamp steep, and difference is to be provided with between led light source and the lamp holder to be beneficial to the radiator that led light source heat in service distributes.The LED bulb of this structure does not move the heat radiation requirement because led light source and lamp holder are installed in the two ends of radiator, and radiator has certain length usually otherwise will reach LED.Be subject to LED operation heat radiation requirement, the lamp body of LED bulb is long than common bulb usually at present, still can't accomplish identical with existing ordinary incandescent lamp bubble.Therefore, the long LED bulb scope of application of this lamp body is restricted, and especially uses in quartzy lamp ﹠ lantern lamp installation to be restricted.The size of radiator must be complementary with light source power: radiator too lampet power is done not quite, and brightness does not reach the illumination requirement of incandescent lamp bulb; The too big illumination of radiator is much of that, but the bigger radiator of volume can cause the light fixture outward appearance not only inharmonious, but also not attractive in appearance.Crystal lamp all is to be used in the higher place of all size, and existing LED bulb can't match.And common quartzy lamp ﹠ lantern lamp installation has dozens or even hundreds of bulb, just do not overcome the above problems to replace existing incandescent lamp bulb with LED.The most light of existing in addition LED bulb are only by the glass lamp shade direct irradiation, and the light diffusion evenly impinges upon do not reach incandescent lamp bulb fully on the quartzy lamp ﹠ lantern light fixture effect of shining out.
Summary of the invention
Technical problem to be solved by this invention is to remedy the defective that prior art exists, compact conformation is provided, install light fixture after length suitable with existing common bulb, be particularly useful for the LED bulb of quartzy lamp ﹠ lantern lamp installation use.
The present invention is solved by the following method.
This LED bulb comprises: printing opacity cover body, radiator, led light source paster, with the lamp adapter assembly that the led light source paster is electrically connected, it is characterized in that:
Described radiator is the barrel-shaped radiator with an end face;
Described printing opacity cover body is installed in the barrel-shaped radiator end face, forms the installation cavity of led light source paster between printing opacity cover body and barrel-shaped radiator end face;
Described led light source paster is installed in the end face of barrel-shaped radiator;
Described lamp adapter assembly is installed in the medial surface of the interior end face of barrel-shaped radiator;
Leave between described lamp adapter assembly and barrel-shaped radiator inwall to screw and be connected the enough gaps that are connected for lamp socket.
Technical problem of the present invention is solved by following further technical scheme.
Be provided with in the described lamp adapter assembly and be used for the driver that led light source drives.
Described barrel-shaped radiator can be circular cylinder, square tube or polygon barrel-shaped radiator.
Described barrel-shaped radiator is by cylindrical shell and the end cap of cylindrical shell one port closed can being constituted, between end cap and barrel-shaped radiator port for being closely connected.Described being closely connected can be that threaded engagement connects.
Described barrel-shaped radiator end face is provided with the louvre that communicates with its inner chamber.
Be distributed with the heat radiation fenestra on the cylindrical shell of described barrel-shaped radiator.
The cylindrical shell of described barrel-shaped radiator is formed by the spaced fin system of enclosing.
Described barrel-shaped radiator end face is provided with the optics light guiding lens that covers in the led light source paster.
Described barrel-shaped radiator end face is provided with the stickup platform of installing for the led light source paster, pastes platform and is provided with two stickup faces for the stickup of led light source paster at least.
Described barrel-shaped radiator is that thermal conductive metallic material is made.As aluminium matter barrel-shaped radiator.
The design principle of LED bulb of the present invention is: under the prerequisite that does not change radiator length and area of dissipation thereof, the lamp adapter assembly that the radiator outer end exposes will be installed in originally, complete hidden being installed in the barrel-shaped radiator, not only can shorten the bulb axial length effectively, realize and the isometric goal of the invention of common bulb, and do not influence the heat sinking function of barrel-shaped radiator at all.Under above-mentioned prerequisite, this structural improvement not only can be hidden in the lamp holder outside former being exposed in the barrel-shaped radiator, the outward appearance of bulb is improved, and be installed in the gap that forms between interior lamp holder of barrel-shaped radiator and the barrel-shaped radiator inwall, just become lamp holder and screw the space that is connected cooperation with lamp socket, when the LED bulb revolves when putting on lamp socket, the barrel-shaped radiator cover of LED bulb covers on outside the lamp socket, lamp socket can be covered fully, make LED bulb and lamp socket visually form one, reach decorative effect from outward appearance.If LED bulb of the present invention is applied to quartzy lamp ﹠ lantern light fixture, the barrel-shaped radiator of LED bulb then can replace the outer sheathing of original quartzy lamp ﹠ lantern light fixture lamp socket, forms one with quartzy lamp ﹠ lantern light fixture.
The beneficial effect that is compared with the prior art of the present invention is:
This LED bulb structure compactness, reasonable is being guaranteed on its energy-conservation, high light efficiency, the long-life basis, and its contour structures can satisfy fully and have installing and using on the light fixtures such as various standard pendent lamps, Crystal lamp now.And, use safer because barrel-shaped radiator can be covered the connecting portion of lamp holder and lamp socket fully.If outside the led light source paster, increase the optics light guiding lens, then can be original go out the luminous point that goes out that the luminous point raising more approaches the incandescent lamp filament.The science design of optics light guiding lens makes that the light that sends is more dazzling.Reach the illumination requirement of quartzy lamp ﹠ lantern light fixture fully.
The present invention's structure both had been applicable to the LED bulb of no driver, also was applicable to tape drive
