Description
Affiliated technical field
The present invention system is about a kind of light-emitting device, refers to a kind of can be applicable on the outdoor lamp stand as street lamp especially, or other illumination or the LED lamp string type road lamp design of making the scape purposes.
Background technology
Be applied at present generally utilize luminescence components such as bulb or High Power LED as two kinds of patterns such as light emitting sources as the light-emitting device of street lamp and so on, wherein the bulb-type light-emitting device is big because of power consumption height, the light decay of bulb, fault rate is high and shortcoming such as replacing bulb frequency height, so present light-emitting device is towards low power consumption, light decay is little and fault rate is lower LED-type light-emitting device development.
The known design that is applied to the light emitting diode road lamp of street lamp and so at present, as shown in figure 15, it mainly is the composition structure design of taking similar CD, that is known light emitting diode road lamp is that a plurality of High Power LED modules (40) are welded on the aluminium matter circuit board (41) one by one, electrically connect its circuit, making aluminium matter circuit board (41) be connected in one again has on the heat radiation lamp socket (42) of large-scale fin, so that High Power LED module (40) is lighted the heat of generation, conduct on this heat radiation lamp socket (42) via this aluminium matter circuit board (41) with large-scale fin, install a lampshade (43) in this High Power LED module (40) front end in addition, this light emitting diode road lamp is mounted on the lamp stand top of street lamp, and the purposes of night-road illumination is provided.
Expose the use of optical diode street lamp only, though can provide light as lighting uses such as street lamps, this light emitting diode road lamp has following many shortcomings in actual use:
1. inconvenient maintenance: the plural light-emitting diode component system in the known light emitting diode road lamp is welded on the aluminium matter circuit board one by one, remove very trouble inconvenience in the assembling construction, and be mounted on when using in the light fixtures such as street lamp when this light emitting diode road lamp, when if arbitrary High Power LED module failure or damage are wherein arranged, general water power worker can't use instrument such as welding gun that the High Power LED module of damaging weld on circuit board time at all voluntarily, again weld new light-emitting diode component again, because of maintenance changes the event of difficulty, usually must whole CD be pulled down by the professional, send original manufacturer merchant maintenance back to for whole group, or make whole group CD and change, the shortcoming of maintenance cost height is arranged.
2. heat dispersion is not good: in the known light emitting diode road lamp, the High Power LED module that it used can produce high temperature when work, because a light emitting diode road lamp must can provide enough light sources by the plural light-emitting diode component of installing, because of those light-emitting diode components system together weldering be located at this aluminium matter circuit board and compile on the lamp holder that conducts to common radiator, because of adding, hot-fluid takes advantage of effect, and the weight based on light emitting diode road lamp is unsuitable overweight, volume is unsuitable excessive to wait restriction down, make that the area of dissipation of heat radiation lamp holder is limited, so under the poorly designed state of cooling mechanism, cause the radiating effect of this light emitting diode road lamp not good, easily make the part light-emitting diode component be easy to burn because of the high temperature that the heat dissipation path difference produces, reduction of service life, and also be subjected to high temperature and influence its task performance together with the electronic building brick on this aluminium matter circuit board, shorten the service life of those electronic building bricks.
3. distribution curve flux difficult design: the light shape that general High Power LED sends is for circular, cause also sub-circular of light shape that known light emitting diode road lamp sends, but the general required distribution curve flux of street lamp is the ellipse of long strip type, to satisfy the needs of road lighting, if known light emitting diode road lamp distribution curve flux will be reached the ellipse of long strip type, its aluminium matter circuit board and large-scale heat radiation lamp socket all will change thereupon, to have the aluminium matter circuit board and the large-scale heat radiation lamp socket of various differences in response to the demand of various distribution curve fluxs, so can cause the huge mould and the waste of manufacturing cost, therefore known light emitting diode road lamp is difficult for the variation design as various distribution curve fluxs.
