Description

The bulb of heavy insulation

Technical field

The utility model relates to a kind of bulb of heavy insulation, particularly relates to the bulb structure that a kind of electrification change-over panel drives at least one light emitting diode, and has comprised that more a slider strengthens the insulating capacity of this electric power change-over panel.

Background technology

Long service life, power consumption are low because light emitting diode (LED) has, high brightness and material be than the multiple advantage of environmental protection, along with the progress of light emitting diode technology and the decline of cost, except use the sign on traffic lights or the electrical equipment with cresset, further be used on environmental decoration, the lighting lamp.In order to allow light emitting diode applicable in the general bulb, existing prior art combines light emitting diode with the shell of existing bulb, as TaiWan, China patent certificate I293807 number " the led lamp bubble of tool constant-current circuit ", this previous patent has disclosed a light emitting diode and the Minoxidil current circuit that a light emitting diode bulb comprises a crown top of burner, a lamp housing, a plurality of series connection.Wherein have electrode on this crown top of burner and be connected, and a plurality of light emitting diode and this Minoxidil current circuit connect, decide electric current and make lumination of light emitting diode, this light emitting diode bulb is loaded onto on the lamp socket of commonly using directly to be used to provide with power supply.But need galvanic current stream owing to drive light emitting diode, the drive circuit that the civil power that exchanges is converted to DC current will constantly produce, accumulate used heat in transfer process.Moreover DC current has also produced many used heat by the impedance of light emitting diode, and too high temperature will be damaged light emitting diode or drive circuit under permanent the use, or reduce service life.Therefore, the dealer develops multiple light emitting diode bulb with radiator structure, shown in TaiWan, China patent certificate M358247 number " is suitable for the LED lamps of various lamp sockets ", should before case disclose a LED radiating module and have a combination end and form an opening, this opening peripheral formation one ring-type buckle slot and corresponding lamp holder combination, the other end of this opening is then in conjunction with a LED light-emitting component, this LED light-emitting component and this lamp holder are electrically connected, and this LED radiating module then is positioned at the function of LED light-emitting component and the peripheral performance of lamp holder heat conduction.The similar light emitting diode bulb that utilizes metal heat sink also is found in TaiWan, China patent certificate M345944 number, M381743 number and discloses No. 201020457.

Aforesaid many preceding cases all utilize metal heat sink (being generally the aluminium radiating piece) to strengthen heat radiation, further make bulb can bear higher power under the prerequisite of not burning.But installing nearly all is the passive type power supply (being designated hereinafter simply as " passive type power supply ") of resistance-capacitance depressurization type in the existing light emitting diode bulb, cooperates the rectification circuit power supply.The passive type power supply has the not good problem of efficient when high-power output, and the circuit volume is also along with increase when improving power, and existing light emitting diode bulb uses passive type power supply reason to be to be easier to test by safety.
