Abstract
An insulation and heat radiation LED bulb lamp comprises a lamp holder, a lamp housing connected with the lamp holder, a power supply disposed in the lamp housing, a radiator, an LED lamp disposed under the radiator, and a lampshade connected with the lamp housing in a twisting manner, wherein the plastic lamp housing is divided into an upper portion and a lower portion through an inflaming retarding plastic component disposed in the middle, and the power supply is disposed in the upper portion of the lamp housing and the radiator is disposed in the lower portion of the lamp housing. Compared with an LED bulb lamp in the prior art, the insulation and heat radiation LED bulb lamp (1) employs the inflaming retarding plastic as the LED bulb lamp housing and realizes the separation of the radiator and the power supply, thereby solving the problem of electric insulation, reducing a temperature of a work environment of the power supply and improving the safety and reliability of the product; and (2) employs an overall design scheme which improves heat radiation effect, reduces the required quantity of heat radiation materials, reduces the production cost of the LED bulb lamp significantly and prolongs a service lifetime of the LED bulb lamp.
Description
Technical field
The utility model relates to a kind of LED bulb lamp.
Background technology
The technological difficulties of high-power LED chip mainly are secondary optics design, heat dissipation design and power system design etc.
Substrate is the basis that solves the great power LED cooling problem, the main heat radiation approach of great power LED is the thermo-contact conduction, the solution of heat dissipation problem should be by good LED package design and material and LED lamp design perfect cooperation, but the basis of heat radiation still is substrate, and adopting insulating materials such as AlN, SiC, BeO is that main ceramic substrate is the direction of praising highly in the industry.
Heat management is the key factor of LED system effectiveness, reliability and long-time stability, and heat accumulative total not only influences the electric property of LED, also may finally cause LED to lose efficacy.Therefore, in order to guarantee the life-span of LED lamp, heat radiation becomes the key technology that white light LEDs is used, and the heat that the minimizing or the LED that dissipates rapidly produce becomes white light LEDs in the matter of utmost importance of using design aspect.Outstanding thermal management technology can further improve the performance of system, improves quantity, the quality of light output and guarantees the reliability that system is long-term.
China is LED encapsulation big country, and the LED device encapsulation in the whole world 80% concentrates on China.But core patents such as white light LEDs encapsulation technology, high-power LED encapsulation heat dissipation technology are but grasped in the big abroad factory hand, if the scale encapsulation is produced and a large amount of outlet, certainly will meet with patent war., high performance novel package structure low-cost with the innovative ideas design will be the invincible position is stood on by China encapsulation enterprise in new round competition keys.
The making of existing LED bulb lamp generally adopts aluminum products to connect radiator in the mode of die casting, extruding and punching press as shell, and the defective of this series products is the cost of manufacture height, and insulating properties is bad.
Summary of the invention
At the problems referred to above, the technical problems to be solved in the utility model provides a kind of good heat dissipation effect, and insulating radiation LED bulb lamp safe in utilization.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of insulating radiation LED bulb lamp, the lampshade that comprises lamp holder, the lamp housing that is connected with lamp holder, is placed in power supply, the radiator in the lamp housing and is placed in LED lamp below the radiator, is connected in the knob mode with lamp housing, described lamp housing is the plastics lamp housing, and described plastics lamp housing is divided into two parts up and down.Power supply is laid on top, and radiating piece is laid in the lower part, and the centre separates with fire retardant plastic spare.
Described radiator comprises the radiating fin on circular bottom plate and the base plate, and described radiator is installed in the plastics lamp housing cavity.
Above the described plastics lamp housing and the following cross-ventilation hole that all has, described cross-ventilation hole is at least 2, lays respectively at the top and following edge of plastics lamp housing.
The utility model has adopted isolated from power fire retardant plastic spare, has both played the effect of insulation, can effectively protect the environment temperature of power work not influenced by radiator again.
Compared with prior art, the utlity model has following advantage:
(1) utilizes fire retardant plastic as LED bulb lamp shell, and radiating piece and power supply are separated, solved the electric insulation problem, reduced the environment temperature of power work, improved security of products and reliability;
(2) the global design scheme of the application's patent has improved radiating effect, has reduced the consumption of heat sink material, reduces the production cost of LED bulb lamp significantly, has prolonged the service life of LED bulb lamp.
Description of drawings
Fig. 1 is the utility model embodiment decomposing state structural representation;
Fig. 2 is a present embodiment cross section structure schematic diagram.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1, the 2nd, the concrete case study on implementation of a kind of insulating radiation LED bulb lamp, comprise lamp holder 1, power supply 3, plastics lamp housing 2, isolated from power fire retardant plastic spare 7, radiator 4, LED lamp 5, lampshade 6, the order of connection of each parts is: lamp holder → power supply → plastics lamp housing → isolated from power fire retardant plastic spare → radiator → LED lamp → lampshade.Wherein, plastics lamp housing 2 is divided into two parts up and down, and power supply 3 is laid on top, and radiating piece 4 is laid in the lower part, and the centre separates with fire retardant plastic spare 7; Lamp holder 1 links in the knob mode with plastics lamp housing 2, plastics lamp housing 2 links in the knob mode with lampshade 6, lamp holder 1, plastics lamp housing 2, lampshade 6 constitute the closed cavity of a hollow, power supply, isolated from power fire retardant plastic spare, radiator, LED lamp are placed in the cavity, on the plastics lamp housing and below open 1 to 2 pore 8 respectively, make the air can free convection.
The preferred packaged type of LED lamp adopts the mode of ceramic eutectic, and promptly LED crystal grain and LED substrate adopt the mode of eutectic to link, and substrate adopts the thin-film ceramics heat-radiating substrate.In addition, also can change the packaged type of LED lamp if any the packaged type that more helps dispelling the heat through checking.
The radiator preferred design is a circular base plate, and regular distribution is the fin of fin shape on the chassis.Also can be altered to other shapes as required.
Isolated from power fire retardant plastic spare and plastics lamp housing can be selected plastics such as PC, BMC, PP, ABS for use.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be noted that, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, packaged type as LED also can be used other modes, radiator also can be designed to other shape, and it is a plurality of etc. that the pore on the plastic casing can be opened.Do not limit at this, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
