Abstract
An LED lamp bulb for an illumination down lamp, which is designed to replace or exchange the halogen bulb, the gaseous discharge illumination lamp bulb, and the tungsten lamp bulb in the existing illumination down lamp. The elastic heat conducting body installed on the outer side of the heat conducting supporting frame of the lamp bulb is used to installed the utility model in the lamp tube of the existing down lamp conveniently and firmly, and the heat emitted when the LED chip works is transferred in the heat conducting wall tube in the lamp tube of the illumination down lamp. The utility model has the advantages that the heat radiation performance is good, the electricity consumption is low, and the working service life is long, and the utility model can be widely used in various down lamps as the illumination lamp bulbs.
Description
(1) technical field: the utility model relates to the illumination Down lamp, relates in particular to the bulb of illumination Down lamp.
(2) background technology: the illumination in the existing train carriage is extensive use of Down lamp, it comprises a lamp tube that plays thermolysis, device halogen emitting bulb or gas discharge emitting bulb in the lamp tube, the supply socket at lamp tube top is connected with the power supply termination of halogen emitting bulb.Halogen electroluminescent lamp or gas discharge electroluminescent lamp bulb (also can be described as fluorescent tube) that this illumination Down lamp uses, the luminous intensity height, but power consumption is also higher, and service life is short.In the prior art, semiconductor light-emitting-diode begins to be used for illuminating lamp by people, and semiconductor light-emitting-diode is called for short LED again, and it has advantages such as power consumptive province and long service life.But the existing illuminating lamp of making of led chip is a kind of light fixture of independent use, can not be installed in the existing illumination Down lamp as bulb, can not use as the bulb (also can be described as the light-emitting device of illumination Down lamp) of illumination Down lamp.
(3) summary of the invention: at halogen emitting bulb (fluorescent tube) in the above-mentioned Down lamp or gas discharge emitting bulb (fluorescent tube) power consumption height, the shortcoming that life-span is short, and the existing illuminating lamp of making of led chip can not be installed on the problem that has now in the illumination Down lamp as bulb, the applicant makes research and improves, a kind of LED bulb (or claiming LED light-emitting device) of the Down lamp that can be used for throwing light on is provided, its power consumptive province, long service life, it can directly be installed in the existing illumination Down lamp, with the based on halogen bulb in the existing illumination of its displacement Down lamp, the gas discharge emitting bulb, osram lamp etc.
The technical solution of the utility model is as follows:
The LED bulb of illumination Down lamp comprises the lamp holder, heat conduction support and the protecgulum that are linked in sequence, the electric control circuit of device led chip and connection thereof on the heat conduction support, the flexible heat carrier of outside device of described heat conduction support.The elastic heat conducting body connects heat-conducting substrate, jockey led chip on the heat-conducting substrate.
In the technique scheme, because at the flexible heat carrier of the outside of heat conduction support device, when the supply socket in the lamp holder access illumination Down lamp of the present utility model, the heat-conducting cylinder wall of lamp tube closely contacts in elastic heat conducting body and the illumination Down lamp, the utility model is installed on reliably in the lamp tube of illumination Down lamp.Secondly, the heat that led chip distributes in the utility model is in proper order by heat-conducting substrate, heat conduction support and described elastic heat conducting body, import the heat conducting wall tube of lamp tube in the illumination Down lamp into, thereby provide a good heat conduction path to the heat that led chip distributes, make led chip that bigger luminous power, stronger luminous intensity and better functional reliability be arranged.It is illuminating source that the utility model adopts LED, has the advantage of power consumptive province, long service life.
(4) description of drawings:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
(5) specific embodiment:
See Fig. 1, the utility model comprises the protecgulum 8 of the lamp holder 1, heat conduction support 5 and the light-transmitting materials that are linked in sequence.On the lamp holder 1 power access end is arranged, it can be plug-in type lamp holder or spiral lamp holder, and Fig. 1 is the plug-in type lamp holder; Heat conduction support 5 is used to connect lamp holder 1 and protecgulum 8, and the control circuit board 2 that is used for device led chip 3 and is electrically connected with chip 3.Led chip 3 can directly weld or be adhered on the heat conduction support 5, but led chip shown in Fig. 13 welds or is adhered on the heat-conducting substrate 6, heat-conducting substrate 6 usefulness securing members are connected on the heat conduction support 5, increase heat-conducting substrate 6 can increase the heat-sinking capability to led chip 3, and makes the easy for installation of led chip 3.Heat-conducting substrate 6 typical cases adopt commercially available 6061 type aluminium bases, and its heat radiation base layer by copper foil layer, heat conductive insulating layer and aluminum material constitutes, and heat-conducting substrate 6 existing good thermal conductivity and thermal diffusivities have insulating property (properties) again.The heat that produces during led chip 3 work imports heat conduction support 5 into by heat-conducting substrate 6.Heat conduction support 5 is made by copper or aluminum material.See Fig. 1, the flexible conducting strip 7 of the outside fixture of heat conduction support 5, it can be made of elastic copper sheets such as phosphor bronze or tin bronzes, and one face closely contacts with heat conduction support 5, and another arc anchor ring closely contacts with lamp barrel 4.Above-mentioned led chip 3 imports heat conduction support 5 into when working heat imports lamp barrel 4 into by elastic heat conducting sheet 7, because lamp barrel 4 has big cooling surface area, therefore the temperature in the time of can effectively reducing led chip 3 work, actual measurement shows, can reduce more than 30 ℃, the luminous power that effectively improves led chip 3 outputs like this, the use led chip also can be saved energy as light emitting source and be improved working life.Above-mentioned led chip can be used commercially available finished product, and for example Ai Disen company produces the MXCS-23-5wLED chip, and its control circuit also adopts prior art.By elastic heat conducting body 7, can conveniently be installed on the utility model in the lamp tube of existing Down lamp securely, replace the light source that has now in the illumination Down lamp with it, extremely convenient for transformation and construction, the based on halogen bulb in the existing train carriage of for example available the utility model direct replacement in the illuminating lamp.
See Fig. 2, it is another embodiment of the present utility model: two arc anchor ring elastic heat conducting sheets 7 of the outside fixture of heat conduction support 5 have interconnected a common sides, insert the middle part of heat conduction support 5, between be welded to connect, described common sides closely contacts with heat conduction support 5, this position also is connected by securing member with heat-conducting substrate 6, welding or bonding led chip 3 on the heat-conducting substrate 6.So led chip 3 is had better heat-sinking capability, remaining explanation is identical with embodiment 1.
