Description
Technical Field
The utility model mainly relates to the technical field of lighting equipment, especially relate to a can promote LED street lamp of illumination definition.
Background
The LED street lamp has the defect of low illumination brightness, so that the illumination definition of the LED street lamp can be obviously reduced in foggy weather, the conventional anti-fog street lamp generally adopts a halogen lamp, but the halogen lamp needs relatively high current, so that the service life of the LED street lamp is short, and because the halogen lamp can generate high radiant heat when the halogen lamp is turned on for a long time, the high radiant heat easily causes the electric device to be scalded, and plastic parts are softened, so that the service life of the whole street lamp is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can promote the LED street lamp of illumination definition to the not enough of prior art existence.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a can promote LED street lamp of illumination definition, including the lamp shade, the lateral wall of lamp shade is the arc, the inside cavity of lamp shade is formed with the installation cavity, the installation cavity is in the front portion of lamp shade is formed with uncovered the uncovered upper cover is equipped with convex lens, convex lens can with the installation cavity seals be provided with the lighting fixture in the installation cavity, the lighting fixture includes the mounting panel that the polylith is parallel to each other, link to each other through the guide pillar between the mounting panel, be fixed blue light LED in the space between two adjacent mounting panels, be fixed white light LED on the mounting panel of foremost.
As an improvement of the utility model, the lamp stand is being fixed at the lateral part of light pole, the lamp stand front portion is provided with conductive contact, conductive contact extends in the installation cavity, the rear portion of lighting fixture is connected on the conductive contact.
Preferably, the side wall of the lampshade is provided with an air vent which can communicate the inside of the installation cavity with the outside air.
As a specific technical scheme of the utility model, the lamp shade is made by brass the chromium has been plated on the inner wall of lamp shade.
Compared with the prior art, the utility model has the advantages of: the LED bulb can not produce a large amount of radiant heat, and has seted up the ventilation hole on the lamp shade lateral wall for the inside difference in temperature of lamp shade and convex lens both sides is very little, can not form the water smoke on the convex lens surface from this and cause the interference to the illumination definition, has also prolonged life simultaneously, and in addition, the light wavelength of the maximum sensitivity that people's eyes can experience under the bright light environment is about 555nm (yellow), and the maximum sensitivity under the dim environment is about 500nm (yellow green) the utility model discloses in be favorable to the driver to ensure eyesight in fog weather through setting up blue light LED.
Drawings
Fig. 1 is a schematic structural diagram of an LED street lamp capable of improving illumination definition in an embodiment of the present invention;
fig. 2 is a schematic structural view of the lamp holder in fig. 1.
Detailed Description
The embodiment of the LED street lamp of the present invention capable of improving the illumination definition will be further described with reference to the accompanying drawings.
As shown in the drawing, this embodiment is a can promote LED street lamp of illumination definition, including lamp shade 1, the rear portion of lamp shade passes through lamp stand 2 and hangs on the light pole, the lateral wall of lamp shade is the arc, by the center of lamp shade to both sides protrusion, inside cavity at the lamp shade is formed with the installation cavity, be formed with the uncovered of this installation cavity in the front portion of lamp shade, convex lens 3 is being fixed in uncovered, seal the installation cavity by this convex lens, convex lens's joint all around is on the inner wall of lamp shade, for the ease of the joint, can set up the round draw-in groove on the inside of lamp shade. Be formed with air vent 9 on the lateral wall of lamp shade, the air vent can communicate the installation cavity inside and outside air, makes the inside and outside difference in temperature of installation cavity less from this, can effectively prevent that the convex lens surface from producing the water smoke, also helps the inside heat dissipation of installation cavity in addition, prolongs electrical components's life. Compared with the vent hole on the halogen lamp, the heat generated when the LED lamp emits light is not large, so the aperture of the vent hole is smaller than that of the vent hole on the halogen lamp, thereby the entering of dust can be obviously reduced, and the illumination efficiency is also effectively improved.
Be provided with the lighting fixture in the installation cavity, this lighting fixture comprises three mounting panels 4 that are parallel to each other, the mounting panel is made by transparent acrylic acid material, these three mounting panels pass through guide pillar 5 interconnect, blue light LED6 is being fixed in the space between two adjacent mounting panels, blue light LED can send the short blue light of wavelength, white light LED7 is being fixed on the mounting panel of foremost, thus, the LED bulb on the whole lighting fixture, not only can be luminous from the front, can also be luminous from the lateral part, the luminous area has been enlarged from this, and then make whole LED lighting fixture have better luminous efficiency, the shortcoming that LED light illumination luminance is not enough has been improved.
In order to further enlarge the light emitting area, the inner wall of the lamp cover is plated with chromium, which has a high degree of finish so that it can emit light well, but the reflection performance of chromium decreases with the increase of temperature, and since the conventional halogen fog lamp generates high radiant heat and ultraviolet wavelength when emitting light, the chromium-plated inner wall may be discolored, so that the reflection efficiency of light decreases. And the LED lamp produces less radiant heat, so the phenomenon that the chromium plating inner wall fades can significantly reduce, is showing from this and has promoted light emission efficiency, and then has promoted illumination scope and illumination intensity.
The lamp holder is fixed on the side portion of the street lamp pole, the front portion of the lamp holder is provided with a conductive contact piece 8, the conductive contact piece extends into the installation cavity, and the rear portion of the lamp holder is connected to the conductive contact piece.
The above description is for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way, and modifications and variations can be made without departing from the principles of the present invention.
