Description
[technical field]
The present invention relates to a kind of lamp housing, be specifically related to a kind of multi-blade wing type LED heat-dissipation lamp housing.
Because the LED street lamp has surmounted the conventional road lamp light source with excellent characteristics such as its high-efficiency long-life safety environmental protection, therefore be the extensively approval of institute of society gradually.But led light source has its specific physical characteristics, therefore in the illumination application facet, requires its lamp housing design must consider various unconventional key elements.Can the height of LED lamp housing heat dissipation design level be directly connected to led light source and raise its long its weak point of keeping away, and should give full play to the superiority of its semiconductor solid lighting, the weakness that can avoid its non-refractory again effectively.In addition, the structural design of lamp housing is for the making full use of of led light source emitted light, rationally luminous intensity distribution is also most important.
[background technology]
Present street lamp of generally being on active service, its light source mainly adopts high-pressure mercury lamp, and some also adopts other light sources such as Metal halogen lamp, high-pressure sodium lamp, electrodeless florescent lamp, CFL.The big temperature of caloric value was higher when these light source devices used, Metal halogen lamp particularly, be ' have a heat send out a light ', be luminous under the high heat condition of high temperature, its light source device must wrap up as shell with high temperature resistant, uvioresistant transparent inorganic thing such as quartz glass, only guaranteeing under the sufficiently high condition of its operating temperature that its luminous efficiency is just enough high, device is just enough durable.
Conventional light source is applied to street lamp, the heat dissipation problem to light source device need not be too much considered in its shell design, particularly need not painstakingly manage to light source device ' cooling ', but it is moulded mainly concentrating on its optical arrangement and lamp housing, pay attention to aspects such as external styling novelty attractive in appearance especially, the core reasons that these 1,100 kinds of moulding of street lamp at present just change ten thousand times without leaving the original aim or stand.In the course of time, masses also naturally and understandably get used to this type of moulding, and once you form a habit, it comes natural to you, and ground thinks that street lamp styling just should shape such as this type of.When the LED of semiconductor solid lighting new science and technology lighting source occurs, however many engineers nearly all Zi habitually with conventional road lamp moulding ' transplanting ' to not being in the LED street lamp application of same types of light sources fully, just not at all surprising.
LED is English ' light emitting diode ' word prefix abbreviation, and the LED lighting source is a semi-conductor solid-state light source.The key technical indexes level of present commercialization LED, the any artificial electric light source that surpasses before this comprises high-pressure mercury lamp, and learn from theory analysis: the space that its index rises also has more than 50% at least, and cost will decline to a great extent, and scape will be known no measure before the visible LED Lighting Industry.
The LED street lamp is the extensively approval of institute of society with the excellent characteristics of its high-efficiency long-life safety environmental protection gradually.Yet be subjected to the influence of conventional road lamp moulding, its lamp design design does not have breakthrough so far, mostly the moulding light maintenance round existing street lamp changes for a short time, cause the superiority performance of led light source not enough, and its weakness of fearing high temperature is because of the bad serious threat that is subjected to of dispelling the heat.Change person is arranged, or increase the ventilation and heat passage, in addition configuration air blast cooling equipment, or adopt heat-pipe apparatus, but all in all, seem mostly and very do not coordinate that resultant effect is not good enough.
The industry of LED illumination has at present been found out many ways aspect the solution heat dissipation problem, radiating effect also has clear improvement.For example, adopt the hot pipe technique scheme, utilize the phase-change energy conversion and the transmission principle of heat-conduction medium, heat exchange is carried out in wide relatively space a large amount of heats that led light source is sent are transferred to lamp housing fast from the luminous site beyond, realizes the effective purpose of cooling of led light source device.Though scheme is good, use cost is higher at present, in addition has leaked phase change medium in case seal failure occurs, and catastrophic effect will be inevitable.And for example, liquid inner-tube structure annular seal space design, cavity is set and injects water base anti-icing fluid being close to the led light source Board position, both can make full use of the characteristics that the aqueous solution has maximum specific heat, and make the light source device temperature gradient greatly alleviate, make full use of liquid fluidity again, the led light source evolution of heat is carried via liquid, spread all over annular seal space any corner in one's power rapidly, fully effectively and at low cost enlarged the efficiently radiates heat area of LED lamp housing, obviously improve radiating effect.Yet blemish in an otherwise perfect thing is that sealing effectiveness is limited by material and technology, can finished product stand the years test? whether the product percent of pass that can stand severe tests up to standard? these problems all will be accepted baptism in long-term market operation.
It is good how to take into account [1] heat dispersion; [2] product safety is reliable; [3] use is easy to maintenance; [4] modern design is attractive in appearance; [5] be easy to recycle; Do [6] cheap relatively these six important aspects of cost search out a combination property and relatively are easy to the technical scheme promoted better, again? this problem to be solved by this invention just.
