Description
Technical field
The utility model relates to a kind of electricity-saving lamp, particularly relates to a kind of industrial and mineral LED lamp.
Background technology
It can directly be converted into light electricity LED.The heart of LED is a semi-conductive wafer, and one end of wafer is attached on a support, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is got up by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is N-type semiconductor, is mainly electronics here.But when these two kinds of semiconductors couple together, between them, just form one " P-N knot ".In the time that electric current acts on this wafer by wire, electronics will be pushed to P district, and in P district, electronics, with hole-recombination, then will send energy with the form of photon.LED lamp is widely used, and view required illumination in various waters also adopts LED illumination in a large number.
LED light fixture is compared with conventional lamp, there is many-sided advantages such as power consumption is little, life-span length, environmental protection, the power consumption of the LED light fixture of equal brightness only has 10% of incandescent lamp, LED lamp life reaches 40,000 hours, be 50 times of service life of incandescent lamp, these advantages make LED light fixture occupation rate of market more and more higher.
The scope of application of LED lamp is more and more wider, and brightness and integrated degree improve constantly, and the heat dissipation capacity while making work is increasing, and LED lamp requires, below 55 DEG C, to have proposed the requirements at the higher level below 50 DEG C for high performance LED lamp.Along with the development of demand, require the luminous efficiency of LED lamp more and more higher, and cause heat dissipation capacity increasing.In the time that temperature exceedes the desired limit of LED lamp, will have a negative impact to the luminescent quality of LED lamp and service life, be even burned.
Utility model content
The utility model provides a kind of novel high-power industrial and mineral LED lamp, and its radiating efficiency is high, can bear the lamp panel that luminous efficiency is higher.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of large power heat pipe cooling LED bulkhead lamp capable, comprise lamp plate pedestal, reflection shield, radiator, radiator cowl and power pack, described lamp plate pedestal both sides are fixedly connected with radiator with reflection shield respectively, on radiator, cover has radiator cowl, radiator cowl rear side connects power pack, described radiator is heat-pipe radiator, comprise at least four heat pipes, regularly arranged fin on heat pipe, between adjacent fin, do not contact, on fin, be provided with hole flanging, heat pipe is through hole flanging, the end of hole flanging contacts with a upper fin, heat pipe and fin are fastenedly connected, described heat radiation center is provided with air-flow exchange hole, described heat pipe inserts lamp plate pedestal and welds by tin cream, between heat pipe and fin, also adopt tin cream welding.
The beneficial effects of the utility model are:
1, because the utility model adopts heat pipe and radiating fin combination radiating mode, and heat pipe inserts lamp plate pedestal and adopt tin cream to weld, and has ensured the adequacy of contact, makes the heat on lamp plate pedestal be passed to fast heat pipe;
2, the hole of passing due to fin heating tube is hole flanging, and the end of hole flanging and above chapter fin are removed, ensure that every fin and heat pipe are maximum area and contact, improve the heat transfer efficiency between heat pipe and fin, and the hole flanging of heat sink and heat pipe are fastenedly connected and weld by tin cream, further improve the heat transfer efficiency between the two;
3, because all there is air-flow exchange hole at the center of heat sink, improve fully the Air Flow between heat sink; And each interval between fin has ensured flowing freely of fin surrounding air, thereby the heat of fin is passed in air fast.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the utility model, is not limited to the utility model.
Below in conjunction with shown in Fig. 1 to Fig. 5, illustrate this patent design feature.
A kind of great power LED heat pipe heat radiation bulkhead lamp capable, comprise lamp plate pedestal 2, reflection shield 1, radiator 3, radiator cowl 5 and power pack 6, described lamp plate pedestal 2 both sides are fixedly connected with radiator 3 with reflection shield 1 respectively, on radiator 3, cover has radiator cowl 5, radiator cowl 5 rear sides connect power pack 6, described radiator 3 is heat-pipe radiator, comprise at least four heat pipes 8, on heat pipe 8, arranged at regular intervals fin 7, between adjacent fin 7, do not contact, on fin 7, be provided with hole flanging 701, heat pipe 8 is through hole flanging 701, the end of hole flanging 701 contacts with a upper fin, heat pipe 8 is fastenedly connected with fin 7, described heat radiation center is provided with air-flow exchange hole 702, described heat pipe 8 inserts lamp plate pedestal 2 and welds by tin cream, between heat pipe and fin, also adopt tin cream welding.Radiator cowl 5 is connected with lamp plate pedestal 2 by bolt 4.
The fin of the present embodiment is fin sheet, and fin sheet tool specification is AA1050 (AL, thermal conductivity is 200W/C.K), and radiating efficiency is high.Hole flanging height is 6MM, fin timing on chip is undertaken by forcing press, because the gap of heat pipe and hole flanging inwall is very little, between heat pipe and hole flanging inwall, fill tin cream, fin sheet has assembled rear Reflow Soldering excessively or baking box condenses tin cream fusing, ensure fully contacting of heat pipe and fin sheet, what heat that guarantee is come from hot pipe conducting was very fast passes to fin sheet.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And the apparent variation of being amplified out thus or variation are still among protection domain of the present utility model.
