Description

Power type LED lamp

Technical field

The utility model relates to a kind of power type LED lamp.

Background technology

LED has long characteristics of luminous efficiency height, power saving and life-span, therefore uses more and more widely as lighting source.But great power LED is because the volume small-power is big therefore very high to the heat radiation requirement, if the heat accumulation that LED produces in luminescence process can not distribute rapidly in less space, will cause LED illumination decay and rapid aging, shorten service life greatly, and the heat dissipation problem that therefore how to solve great power LED is that LED promotes a key technology that faces to normal lighting.

Gate light on the vehicles such as automobile, aircraft, reading lamp etc. still generally use traditional neon tube bulb at present, its power consumption is big, and the brightness of low power LED lamp is low, adopts power type LED lamp to replace conventional lighting sources then to can further improve the application of illuminating product.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of good heat dissipation effect is provided, assembles simple and rapid power type LED lamp.

The technical scheme that the utility model adopted is: the utility model comprises at least one led light source, described power type LED lamp also comprises heat dissipation base, insulation sleeve, interface arrangement, described led light source comprises chip, heat-dissipating casing, two pins, described heat dissipation base comprises pedestal, described pedestal end face is provided with counterbore, a side or two relative sides are provided with boss, described counterbore size and described heat-dissipating casing are measure-alike, there is through hole to be connected in the described boss with described counterbore, the side of described boss is provided with breach, described heat-dissipating casing is fixedly connected in the described counterbore, two described pins pass described through hole respectively and are electrically connected with described interface arrangement, described insulation sleeve is socketed on the described boss, and described interface arrangement is socketed on the described insulation sleeve.

Two described pins connect resistance, diode respectively and are connected with described interface arrangement.

Described interface arrangement is two electrode caps or a bayonet socket light fitting or a screw socket light fitting.

Perhaps, described led light source has two, and two described led light sources are in series.

Described pedestal is a cuboid, and described boss is cylindrical.

The beneficial effects of the utility model are: because heat-dissipating casing described in the utility model is fixedly connected in the described counterbore, two described pins pass described through hole respectively and are electrically connected with described interface arrangement, described insulation sleeve is socketed on the described boss, described interface arrangement is socketed on the described insulation sleeve, the heat that described led chip produces at first passes to described heat-dissipating casing, be transmitted to described heat dissipation base through described heat-dissipating casing again, because described heat dissipation base volume is bigger, so good heat dissipation effect; Owing to have through hole to be connected in the described boss with described counterbore, the side of described boss is provided with breach, when the described led light source of assembling, described heat-dissipating casing is put into described counterbore, two described pins pass the described breach of described boss side surfaces and reach outside the described breach along described counterbore, again described insulation sleeve is placed on the described boss, and with two described pins and the welding of described interface arrangement, at last described interface arrangement is socketed on the described insulation sleeve, therefore easy to assembly, the trouble that need draw described pin when having avoided not having described breach, productivity ratio improves greatly, so the utility model good heat dissipation effect, assemble easy to be quick;

Because two described pins of the utility model connect resistance, diode respectively and are connected with described interface arrangement, described resistance plays step-down and metering function, make that the voltage at described led light source two ends is rated operational voltage, therefore the voltage that is connected on the described interface arrangement can be bigger than the rated voltage of described led light source, adapt to lighting voltage needs such as automobile, aircraft, described diode plays the effect of reverse protection, so the utility model applied range;

Because interface arrangement described in the utility model is two electrode caps or a bayonet socket light fitting or a screw socket light fitting, therefore go for existing different electrical power interface, adopt two electrode caps the utility model can be installed on the both shoulders tube face, a bayonet socket light fitting or a screw socket light fitting can be installed on the utility model respectively bayonet-type bulb seat or screw-socket bulb seat, so the utility model can be installed on the basis that does not change existing lamp socket, it is convenient to substitute;

Because pedestal described in the utility model is cuboid, described boss is cylindrical, and is supporting with existing lamp socket like this, and install firm firm, so the utility model and existing bulb are general substituting good, install firm firmly.
