Description
Technical field
The present invention relates to a kind of road lamp device, relate in particular to the road lamp device that a kind of LED of employing makes light source.
Background technology
LED is a semiconductor light-emitting-diode, be after HF lamp without electrodes the 4th generation light source because its brightness height, energy consumption is low, is used widely in fields such as traffic lights, electronic displays.And, also be in the starting stage as the street lamp of road lighting.Road lamp device generally includes the light cover that is positioned at fender lamp base down and is positioned at upside and flexibly connects with described lamp socket, and lamp socket is connected with lamp stand, and the wiring board that is used for the reflector of reflection ray and is provided with led light source is fixed in described lamp socket.When the field maintenance of high-altitude,,, increased maintenance difficulty if the dismounting wiring board just must take out reflector together owing to structural reason.
Reflector is generally planar structure, which is provided with the reflecting coating material, because LED has certain lighting angle, the reflector of this planar structure can not produce the effect of optically focused, though illuminating area is big, but intensity of illumination is low, just must increase the power of street lamp in order to reach same intensity of illumination, thereby reduce its energy-saving effect.
In addition, the street lamp desired power is bigger, light application time is long, though LED belongs to cold light source, owing to a street lamp is made up of tens led array usually, so it is when energising, also can produce heat, if semiconductor devices working above under the condition of its rated temperature, then can reduce the luminous efficiency of LED, even make its damage for a long time.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of LED road lamp device of being convenient to keep in repair, to solve when the field maintenance of high-altitude the inconvenient problem of wiring board dismounting.
For solving the problems of the technologies described above, technical scheme of the present invention is: the LED road lamp device, comprise the lamp socket that is positioned at downside and is provided with lampshade, with the light cover that is positioned at upside and flexibly connects with described lamp socket, with the reflector that is installed on the described lamp socket, and the wiring board that is provided with the led array light source, described reflector comprises a top that is provided with perforate, described wiring board is removably fixed in the upside at the top of described reflector, and described led light source stretches out the top of reflector downwards from described perforate.
As a kind of improvement, described reflector also comprises the reflection skirt that also extends that is surrounded on described top downwards, and described reflection skirt is provided with a horizontal flange, and described reflector is fixedlyed connected with described lamp socket at the flange place.
Improve as another kind, it also comprises together first seal of described reflector and lampshade can being tightly connected of annular, and is arranged between the top of described reflector and the wiring board and is clamped with second seal.
Improve as another kind, the upper side of described wiring board is provided with heat-dissipating fin.
After having adopted technique scheme, the invention has the beneficial effects as follows: because described reflector comprises a top that is provided with perforate, described wiring board is removably fixed in the upside at the top of described reflector, described led light source stretches out the top of reflector downwards from described perforate, such structure not only can not influence led light source and shine downwards, and when the field maintenance of high-altitude, only need open light cover, then wiring board and being connected of reflector are taken apart, just wiring board can be taken out, and need not to dismantle reflector, thereby reduced maintenance difficulty.
Because also comprising, described reflector is surrounded on reflection skirt described top and that extend downwards, described reflection skirt is provided with a horizontal flange, described reflector is fixedlyed connected with described lamp socket at the flange place, like this, the reflection skirt will reflect the light of led light source side direction irradiation, thereby produce the effect of optically focused, improved intensity of illumination.
Because it also comprises together first seal of described reflector and lampshade can being tightly connected of annular, and be arranged between the top of described reflector and the wiring board and be clamped with second seal, thereby between reflector, lampshade and wiring board, formed an airtight space, avoid dust and winged insect to enter in this space, guarantee the light transmission of lampshade.
Because the upper side of described wiring board is provided with heat-dissipating fin, thereby has increased the area of dissipation of wiring board, has reduced the temperature of led light source, has improved the dependability of led light source.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structure cutaway view of the embodiment of the invention;
Fig. 2 is the optically focused principle schematic of reflector embodiment illustrated in fig. 1.
The specific embodiment
The LED road lamp device, as shown in Figure 1, lamp socket 1 is positioned at downside, and light cover 7 is positioned at upside and hinged with described lamp socket 1, when light cover 7 fastens with lamp socket 1, can form the inner space of a sealing.Reflector 3 comprises that one is provided with the top of perforate and is surrounded on reflection skirt 31 described top and that extend downwards, and described reflection skirt is provided with a horizontal flange, and described reflector 3 is fixedlyed connected with described lamp socket 1 at the flange place.Be provided with first seal 2 of an annular between the horizontal flange of described reflector 3 and the lampshade 6, this first seal 2 not only makes its both binding face realize sealing, and both link together with it.Be clamped with second seal 32 between the top of described reflector 3 and the wiring board 4, the top of described reflector 3 is provided with the annular groove around described perforate, described second seal 32 is arranged in the described annular groove, like this, second seal 32 after the distortion is completely restricted in annular groove, when second seal 32 adopts elastomeric material to make, not only can eliminate owing to connect of the influence of the mismachining tolerance of end face sealing effectiveness, and second seal 32 when being subjected to cramping, also can not stretch to the perforate at reflector top, influence the installation of wiring board 4.Certainly, for simplified structure, the top of reflector 3 is not provided with annular groove, directly with second seal, 32 crampings between the top and wiring board 4 of reflector 3, also can reach certain sealing effectiveness.Like this, between reflector 3, lampshade 6 and wiring board 4, just form an airtight space, avoided dust and winged insect to enter in this space, guaranteed the light transmission of lampshade.
The wiring board 4 that is provided with led array light source 5 is removably fixed in the upside at the top of described reflector, and described led light source 5 is from the top that reflector is stretched out in described perforate downwards, and the upper side of described wiring board 4 is provided with heat-dissipating fin 41.
Fig. 2 shows the optically focused principle of reflector 3.The effect of reflection skirt 31 is that the light that the led light source side direction is shone is reflected to the middle part, to improve its intensity of illumination.The shape of the longitudinal section of the height of reflection skirt 31 and reflection skirt 31 can be according to the luminous angle of led light source, the shape of the longitudinal section of described reflection skirt 31 is curved, this shape more helps improving the spotlight effect of led light source, certainly, for the ease of processing, reduce cost, adopt rectilinear reflection skirt 31 also can reach certain spotlight effect.
