Description
Technical field
The utility model relates to a kind of light emitting diode road lamp structure.
Background technology
Lighting apparatus is a daily necessities indispensable in the daily life, changed people's life style, now in general family or the public's indoor scenarios, all can see and use lighting apparatus miscellaneous, for example: fluorescent lamp, illuminating lamp, desk lamp, pendent lamp, neon light or the like, can be improved by lighting apparatus for the dim inconvenience that brings.
For different lighting apparatus, the purposes of its application also has difference, for example: general fluorescent lamp, illuminating lamp, desk lamp ... etc., it is for the use of general illumination, and the lighting apparatus that some specific uses are also arranged for example: night-light, be and be applied to the illumination that people are provided when sleeping, its luminous power is lower, only is auxiliary usefulness.
Above-mentioned lighting apparatus adopts early stage incandescent lamp bulb as illuminating source mostly, and because light emitting diode (Light Emitting Diode, LED) fast development, and it is low that light emitting diode has power consumption, component life is long, need not warm up advantages such as lamp time and reaction speed be fast, add that its volume is little, vibration resistance, be fit to volume production, therefore light emitting diode generally is used in information, on the indicator lamp and display unit of communication and consumption electronic products, as mobile phone and personal digital assistant (Personal DigitalAssistant, PDA) screen backlight source, various outdoor display, traffic signal light and car light etc.
And along with the lifting of technology, develop gradually and the light emitting diode that can replace numerous lighting apparatus illuminating sources, by the characteristic of light emitting diode, can effectively improve lighting apparatus and use the problem of incandescent lamp bulb as illuminating source.
But, need reach identical illumination with incandescent lamp bulb, need more light emitting diode, and need to adopt the higher light emitting diode of power just can reach identical illumination, and adopt the higher light emitting diode of power also can produce more heat energy, therefore, need to use light emitting diode to replace the illuminating source of incandescent lamp bulb, need overcome the problem of LED heat radiating as lighting apparatus.
Wherein the simplest way is and adds heat abstractor on the circuit board that disposes light emitting diode in lighting apparatus, by on circuit board, adding heat abstractor, generally speaking heat abstractor is the heat abstractor of a plurality of fin shapes, promptly light emitting diode is dispelled the heat, to solve the problem of high heat energy that light emitting diode lighting equipment is produced by the mode of free convection.
But for the application of some special occasions, for example: street lamp, outdoor lighting apparatus ... wait, outdoor dust tends to be deposited in the heat abstractor, promptly can be deposited between the fin gap of heat abstractor, and then influence the radiating efficiency of heat abstractor, and cause the decline of LED heat radiating efficient, and cause the damage of light emitting diode, reduce the service life of light emitting diode.
In order not make dust accretions in heat abstractor, to reduce the radiating efficiency of heat abstractor, therefore most likely heat abstractor is provided with dust guard, use the accumulation of avoiding dust having influence on the radiating efficiency of heat abstractor, but consider the problem of heat radiation, but offer some holes at dust guard, so that the heat radiation of heat abstractor, and the hole that dust guard is offered can cause entering of dust also, being deposited in the heat abstractor once more, and influence the radiating efficiency of heat abstractor.
In sum, prior art has existed outdoor environment to use light emitting diode lighting equipment can't have dustproof and good radiating efficiency problem simultaneously concurrently always since the midium or long term as can be known, therefore is necessary to propose improved technological means, solves this problem.
