Description
Technical field
The present invention relates to a kind of street lamp, particularly use paster LED as the street lamp of light source.
Background technology
Due to LED light emitting source, the light that it irradiates has one-way, does not have the diffusion of light, so usually all carry out secondary optical design in the front end of light emitting source, namely at light emitting source front end mounted lens, the light that LED is sent produces diffuse effect.
Along with the renewal of technology, develop paster LED, this LED light emitting source is pasted on PCB surface, many LED luminescence chips are encapsulated in a very little area, adopt lighter PCB and reflector material, the reasonable aluminium sheet of usual employing heat dispersion, as the base material of PCB, substantially reduces the volume and weight of electronic product, and often sheet PCB can install multiple paster LED light emitting source.And before this, be all many light emitting sources are packaged into together with lens a lamp pearl, volume and weight is all very large, and this lamp pearl needs independently heat abstractor, such that final light fixture volume is large, weight large, complex structure.
The patent No. is 201410275139.7 and is called that the Chinese patent of " a kind of LED street lamp " discloses the street lamp of a kind of paster LED as light emitting source, adopt multiple PCB illuminating module, because heat sink, PCB luminous plaque, lens board group are all encapsulated in light fixture by upper end cover by it, so louvre must be offered on light fixture.So just cause that lamp holder volume is large, the problem of complex structural designs.Especially heat sink is enclosed in lamp holder, have impact on radiating effect, under overheated working environment, easily shorten the service life of LED light emitting source.
Summary of the invention
In order to solve, prior art volume is large, weight is large, heat dispersion is poor, baroque problem, provides a kind of paster LED street lamp, and this street lamp volume is little, lightweight, excellent heat dissipation performance, simple and reasonable.
For achieving the above object, the present invention is by the following technical solutions:
A kind of paster LED street lamp, comprise shell, the PCB of paster LED light emitting source is installed, wiring hole is provided with on rear side of shell, it is characterized in that: PCB quantity is one piece, bonded by heat-conducting silicone grease between PCB and shell, the outer end of the corresponding PCB of shell is provided with the heat sink of some outwardly convexs, and shell adopts aluminium one-step die casting; Be provided with lens board in the front end of PCB, described lens board quantity is one piece, and lens board is provided with the lens corresponding with every paster LED light emitting source, and be provided with dustproof glass in lens board front end, dustproof glass is fixedly connected with case nose.
Above-mentioned a kind of paster LED street lamp, be is characterized in that being provided with screw inside described shell, PCB, lens board offers the through hole corresponding with screw, lens board, PCB are fixed on screw inside the shell by screw.
Above-mentioned a kind of paster LED street lamp, is characterized in that shell being provided with several screws, and opening sheet card one end props up dustproof glass lower end, and the other end is fixed on the screw with case nose by screw.
Above-mentioned a kind of paster LED street lamp, is characterized in that shell is concave inward structure near wiring hole position, and for installing the driver of paster LED, the outer face at described shell indent position flushes with the heat sink of homonymy.
Above-mentioned a kind of paster LED street lamp, is characterized in that case nose is provided with the fluting of through end face, and sealing strip inlay card is in fluting, and dustproof glass is arranged on the front end of sealing strip; After dustproof glass is arranged on shell, the front end face of dustproof glass flushes with the front end face of shell.
Shell and fin are integrated, adopt the good aluminium of heat dispersion to carry out disposable die cast, decrease the functional part of heat radiation, quick for installation during manufacture, convenient, simultaneously because fin is direct and atmosphere, heat dispersion is better.
The present invention is owing to having carried out heat sinking function parts the design simplified most, and the efficiency reducing manufacturing cost, alleviate the burden of the manufacturing, improve the manufacturing, makes light fixture cost decline obviously.
The present invention adopts the PCB of a monoblock paster LED, use the lens board of a monoblock corresponding with it simultaneously, the manufacturing cost that reduce further light fixture, the burden alleviating the manufacturing, improve the efficiency of the manufacturing, and fitting structure is more compact, without any unnecessary parts.
In addition, owing to have employed heat-conducting silicone grease bonding aluminum matter pcb board and aluminum shell, make paster LED change into plane by the concentrated heat radiation of single LED and dispel the heat, improve radiating efficiency, reduce the temperature of light fixture.Through reality test, after adopting this structure, the temperature of PCB aluminium base is usually also between 50-60 degree, and under this temperature environment, the service life of paster LED is extended.
The inner chamber outer end of installing paster LED driver flushes with the outer face of heat sink, and the profile of light fixture is more neat, instant packed and transport.
Sealing strip compresses by dustproof glass, and make light fixture form closed inner chamber, need to offer convection holes on lamp outer casing with prior art and form a sharp contrast, dust-proof effect obtains qualitative leap, extends the service life of electronic unit.
