Description

Light-emitting diode lamp module

Technical field

The present invention relates to a kind of light-emitting diode lamp module, particularly a kind ofly can conveniently replace the light source or the light-emitting diode lamp module of heat dissipation element.

Background technology

(light emitting diode LED) holds advantages such as environmental protection, energy-conservation and changeableization of color under the arm to light emitting diode, shows up prominently gradually, therefore also replaces other light fixture gradually in recent years.Yet light emitting diode (LED) often follows the not good used heat that causes of energy conversion efficiency to produce in application process.

Yet the used heat that light emitting diode (LED) is produced will cause its temperature to rise.Thus, in brightness output, light color service life output and light emitting diode (LED) for light emitting diode (LED), very big influence is arranged all.

With temperature the influence of light emitting diode (LED) brightness output is explained, the contact temperature of light emitting diode (LED) (junction temperature Tj) can influence the luminous flux of this light emitting diode (LED), and its relational expression can be like following expression:

${\mathrm{\Φ}}_V\left(T_2\right)={\mathrm{\Φ}}_V\left(T_1\right)e^{-\mathrm{k\Δ}{T}_j}$

Wherein, Φ v (T1) and the luminous flux of Φ v (T2) representative when contact temperature is T1 and T2, k is a temperature parameter, Δ Tj representes that contact temperature changes (T2-T1).With the typical case red-light emitting diode (LED) of tangerine light, Huang (amber) coloured light is an example, when its contact temperature increased by 75 ℃, its luminous flux can reduce to original 50%.In other words, when the temperature rising of light emitting diode (LED), will cause the brightness of light emitting diode (LED) to descend.

And with temperature the influence of light emitting diode (LED) brightness output is explained; Contact temperature Tj also can change simultaneously the main optical wavelength (dominant wave length) of light emitting diode (LED) and make color change, and the relational expression of this main optical wavelength and temperature can be like following expression:

Wherein, λ d (T1) and λ d (T2) are the main optical wavelength when contact temperature is T1 and T2, can know that by above relational expression the main wavelength of light of light emitting diode (LED) can increase 1nm when temperature increases by 10 ℃.For the red light-emitting diode that is applied in automobile (LED) lamp, because its color gamut of allowing is very big, so its influence is little.But, as be applied in Huang (amber) look light emitting diode (LED) lamp of automobile, (about 5～10nm), the influence of this wavelength shift just can not be ignored because its color gamut of allowing is less.Anticipate promptly, the temperature rising when light emitting diode (LED) might cause light emitting diode (LED) issued light look to change.

In addition, general light emitting diode (LED) is coated with the epoxy resin that does not influence optical property, but when temperature rose to the glass transformation temperature of epoxy resin, this epoxy resin can be changed into the material of rubber kenel by the solid glass shape.Thus, with the thermal coefficient of expansion that causes epoxy resin simultaneously (Coefficient ofThermal Expansion, CTE) anxious increasing.Relative, also make epoxy resin make the wiring displacement of light emitting diode (LED), and then cause the inefficacy of light emitting diode (LED) because of thermal expansion.

From the above, be very important for the cooling mechanism of light emitting diode (LED) element.Yet existing heat dissipation design to light emitting diode (LED) module is the structure that radiator and lamp socket is integrated as integral type.And light emitting diode (LED) is under the varying environment condition, and desired radiating effect also is not quite similar.Therefore, often for the lamp source in response to the light emitting diode under the different operating condition (LED), cause the restriction in the use, can't carry out design alteration, lamp socket and the radiator that just needs to change whole group to be meeting its radiating requirements, and be difficult for taking into account the demand of heat transfer.Thus, puzzlement or the increase in assembling man-hour with causing in the manufacturing and are unfavorable for that also follow-up maintenance and dress change.

Summary of the invention

In view of above problem; The object of the present invention is to provide a kind of light-emitting diode lamp module; Use that to solve prior art existing in response to the radiating requirements under the different condition, and will put in order the group lamp socket and radiator is replaced together, cause the problem of alternative costs waste.

The light-emitting diode lamp module that the present invention disclosed, it comprises at least one lamp socket, a light source substrate and a radiating seat.Lamp socket has one first and an outside wall surface, and light source substrate has at least one light emitting diode.Light source substrate is disposed at first, and at least partly contacts with first face.Radiating seat has at least one radiating fin and at least one storage tank, and lamp socket is disposed at storage tank, and partly contacts with radiating seat.Light source substrate is with thermal energy transfer to the lamp socket that light emitting diode produced, and to radiating seat, radiating seat looses heat energy through radiating fin and removes lamp socket with thermal energy transfer.

According to above-mentioned light-emitting diode lamp module, lamp socket is arranged at the storage tank of radiating seat.Wherein, be dismountable two independent components between lamp socket and radiating seat, and can dismantle easily and assembly to each other.When light-emitting diode lamp module under different environment for use conditions, when need using the light emitting diode of different kenels, the replacement radiating seat that the user can be suitable satisfies the lamp socket radiating requirements.So such light-emitting diode lamp module can reduce the user significantly and assemble the spent time of light-emitting diode lamp module, and be beneficial to follow-up maintenance and hyperphoric.
