Background technology
Light emitting diode (Light Emitting Diode; Electronic building brick that can be luminous during LED) for a kind of the energising, its principle of luminosity is to convert electrical energy into light, just P-N engage is injected minority carrier, it is combined with majority carrier again and send the diode of natural daylight, desire to make the electron-hole pair that LED is luminous more than well must having extremely directly compound.After LED imposed forward bias voltage drop, space charge layer narrowed down, based on the fermi level difference of both sides, so the main carrier of P-N both sides injects N side and P side respectively.Because the minority carrier of both sides rolls up, and makes and carries out the compound again of a large amount of hole-duplets between the both sides, and emit enough number of photons; The kind of light emitting diode roughly comprises series such as GaAs, GaN, A1InGaP at present.In addition, at GaAs, GaN, the doping nitrogen-atoms also can change its luminous color in the AlInGaP series.
Show according to statistics: power is to be about 1500 hours the average life of 50 watts based on halogen bulb; High brightness is that 360 lumens, power are but can reach more than 20000 hours average life of 5 watts LED bulb.Therefore, compared to traditional based on halogen bulb, the power consumption of LED bulb approximately only 1/10th, the life-span is but up to ten to 15 times.Because compared to existing based on halogen bulb, nowadays advantages such as the LED bulb has light weight, volume is little, power consumption is low, long service life have Xu Guojia all to take up to formulate relevant laws and regulations, eliminate the concrete time-histories table that changes traditional based on halogen bulb to stipulate.
On practice utilization aspect, based on halogen bulb (particularly existing market widely peddle AR111 based on halogen bulb) possesses two conductive connecting pins that extend out from its base portion usually, overlaps each other with the electrode pin with existing halogen lamp socket.Yet, with regard to LED, utilize electric current and driver IC (DriverIntegrated Circuit usually; Driver IC) drives, therefore LED must be installed on the circuit board usually, to form a LED assembly.Simultaneously, can bring into play preferable illuminating effect in order to make LED, can need usually provides necessary heat sinking function to LED.
On above argumentation basis, because existing halogen lamp socket all lacks the design of radiating module mostly, while LED assembly lacks the conductive connecting pin with electrode pin compatibility again, therefore, aspect heat sinking function and electrical overlap joint, existing halogen lamp socket can't satisfy the demand of LED assembly at all.In case when based on halogen bulb eliminated comprehensively change after, existing halogen lamp socket can not be used for overlapping based on halogen bulb, can not be used for again directly overlapping the LED assembly and converts the LED lamp socket to, have to follow to be eliminated comprehensively and change, be to waste very much really.
Summary of the invention
Technical problem and purpose that the utility model institute desire solves:
Because in the prior art, the halogen lamp socket lacks the design of radiating module, and the LED assembly lacks the conductive connecting pin with electrode pin compatibility again, cause based on halogen bulb in case eliminated comprehensively change after, the halogen lamp socket just must be eliminated thereupon comprehensively and be changed.For this reason, main purpose of the present utility model is to provide a kind of heat radiation and electrical adapter, and it is in order to transferring the LED assembly in existing halogen lamp socket, and utilizes radiating module to overcome above-mentioned problem simultaneously with electrical combining of adapter.
The technological means that the utility model is dealt with problems:
The utility model provides a kind of heat radiation and electrical adapter for solving the technological means that prior art problems adopted, and supplies a light emitting diode (Light Emitting Diode; LED) assembly is transferred in a halogen lamp socket, and comprises a radiating module and an electrical adapter.Radiating module for this LED assembly of binding, and comprises a heat radiator body and a plurality of from the extended radiating fin of heat radiator body radiation.Electrically adapter comprises an adapter body and at least two conductive connecting pins.The adapter body is screwed together in heat radiator body from body, and power supply property overlap joint LED assembly, and conductive connecting pin extends from the adapter body, for overlap joint halogen lamp socket, the LED assembly is electrically communicated with the halogen lamp socket.
The utility model effect against existing technologies:
In the prior art, because the halogen lamp socket lacks radiating module, the LED assembly lacks the conductive connecting pin with electrode pin compatibility, thereby causes the LED assembly can't directly be overlapped in the problem of halogen lamp socket.Compared to prior art, the utility model provides a kind of heat radiation and electrical adapter, and it is in order to transfer the LED assembly in the halogen lamp socket.Because heat radiation possesses radiating module with electrical adapter, therefore can effectively satisfy the demand of LED assembly radiating.In addition, because heat radiation possesses electrical adapter with electrical adapter, and electrically adapter comprises at least two conductive connecting pins, therefore the LED assembly is electrically communicated each other with the halogen lamp socket by electrical adapter.Therefore, can effectively overcome the heat radiation and the electrical problem of overlap joint, make present halogen lamp socket can continue to continue to use to combine with the LED assembly and avoid being eliminated and changing along with based on halogen bulb.
