A kind of high-power thermal release bulb lampTechnical field
This utility model is related to a kind of high-power thermal release bulb lamp, belongs to field of LED illumination.
Background technology
It is at present, using radiating fin and lamp holder " upper and lower " mode structure, to be somebody's turn to do with existing high-power bulb lamp great majorityBecause affected by gravity, heat can be superimposed structure light fixture heat, and power large scale is little, make radiating become high-power bulbThe subject matter of lamp, and because temperature drift has influence on light fixture service life, thus generally require addition wind and disperse active heat removal,But active heat removal has that noise is big, fan life is short, and parts are more, and assembling procedure is more, cost uprises again.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-power thermal release bulb lamp, realizes thermal source pointFrom, thermal source superposition is reduced, reduce local pyrexia；Further, there is provided a kind of high-power thermal release bulb lamp, it is right to realizeThe heat loss through convection of LED modules；Further, there is provided a kind of high-power thermal release bulb lamp, realize to the right of lighthead powerFlow heat dissipation.
To solve above technical problem, the technical solution adopted in the utility model is：A kind of high-power thermal release bulb lamp,Including lampshade, lighthead power and LED modules, the lighthead power runs through whole lampshade, and the LED modules are located at lampshade bottom,The lighthead power is separated with the position of LED modules, is connected by electric wire between the two.
The lampshade middle part is radiator, and the radiator is arranged at LED modules top, described to dissipate for the radiating of LED modulesLeave cavity and pass through for lighthead power in the central authorities of hot body.
Lighthead power shell is provided with outside the lighthead power, the top of the lighthead power shell is provided with radiatingHole, bottom is Open architecture.
The lampshade also includes being arranged on the upper lid on radiator top, and the upper lid is fixed on radiator outside lighthead powerOn shell, on the upper lid air vent is provided with.
The lampshade also includes being fixed on the PC covers of radiator bottom, and the PC covers are arranged at LED modules lower section.
The PC covers are fixed on radiator by end cap, and on the end cap air vent is provided with.
Installation end such as the lighthead power is provided with lamp holder.
The beneficial effects of the utility model are：
Lighthead power is separated with the position of LED modules, reduces the thermal source superposition of same position, drops local pyrexiaIt is low, extend the service life of light fixture；
Further, the radiator above LED modules, by cross-ventilation the heat that LED is produced is distributed, and reduces LEDThe heat of module；
Further, it is provided with lighthead power shell outside power supply, the top of the lighthead power shell is provided with scatteredHot hole, bottom is Open architecture, and when power supply adstante febre, lighthead power outer casing bottom realizes cross-ventilation with top louvreRadiating, by the radiating respectively of LED modules and power supply, makes heat without coincidence, and overall heating is reduced, and light fixture service life increases.
Therefore, a kind of high-power thermal release bulb lamp provided by the utility model, realizes thermal source separation, reduces thermal sourceSuperposition, reduces local pyrexia, and realizes to LED modules and the difference heat loss through convection of lighthead power, reduces overall heating, lampTool service life increases.

Specific embodiment
This utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating thisThe technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
A kind of high-power thermal release bulb lamp as shown in Figures 1 to 4, including lampshade 1, lighthead power 2 and LED modules 3, instituteLighthead power 2 is stated through whole lampshade 1, the LED modules 3 are located at the bottom of lampshade 1, the lighthead power 2 and LED modules 3Position is separated, and is connected by electric wire between the two, and lighthead power 2 is separated with the position of LED modules 3, reduces same positionThermal source superposition, reduce local pyrexia, extend the service life of light fixture；
The middle part of the lampshade 1 is radiator 4, and the radiator 4 is arranged at the top of LED modules 3, radiates for LED modules 3,LED modules 3 are screwed on the screw position of radiator 4, and the central authorities of the radiator 4 leave cavity for lighthead power 2Pass through, the heat that LED is produced is distributed by radiator 4 by cross-ventilation, reduce the heat of LED modules 3, as shown in Figure 4Heat dissipation path two.
It is provided with lighthead power shell 5 outside the lighthead power 2, the top of the lighthead power shell 5 is provided with scatteredHot hole, bottom is Open architecture, and bottom and the LED modules 3 of lighthead power shell 5 are screwed, when power supply adstante febre,The Open architecture of the bottom of lighthead power shell 5 realizes cross-ventilation radiating, radiating road as shown in Figure 4 with top louvreFootpath one.
The lampshade 1 also includes being arranged on the upper lid 6 on the top of radiator 4, and radiator 4 is fixed on lamp holder by the upper lid 6On outer casing of power supply 5, it is screwed between upper lid 6 and radiator 4, air vent is provided with the upper lid 6, upper lid 6 is rightWhile 4 fixations of radiator, the cross-ventilation of radiator 4 and lighthead power shell 5 is not interfered with.
The lampshade 1 also includes being fixed on the PC covers 7 of the bottom of radiator 4, and the PC covers 7 are arranged at the lower section of LED modules 3,PC covers 7 pairs of LED modules 3 and shields.
The PC covers 7 are fixed on radiator 4 by end cap 8, and air vent is provided with the end cap 8, and end cap 8 passes through spiral shellSilk is fixed, PC covers 7 is fixedly secured on radiator 4, and the air vent on end cap 8 makes the air in lighthead power shell 5Convection current is unaffected, and the heat of power supply can be shed by end cap 8.
Installation end such as the lighthead power 2 is provided with lamp holder 9, is easy to of the present utility model using installation.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the artFor art personnel, on the premise of without departing from this utility model know-why, some improvement and deformation can also be made, these changeEnter and deform also to should be regarded as protection domain of the present utility model.
