Abstract
The utility model relates to an integrative street illuminating lamp with an LED as a light source, which belongs to the field of illuminating equipment. The integrative street illuminating lamp adopts a high-power white-light LED as the light source of a street lamp; the high-power white-light LED is fixed on an aluminum-based PCB pole, and a reflector which can form rectangular light spots is fixed at the rear part of the LED light source. Finally, the integration is embedded in a supporting arm of a street lamp post. The utility model is characterized in that the heat dissipation of a PCB panel is combined with a lamp case and the lamp post, so the heat dissipation efficiency is greatly improved, the heat dissipation of the LED can be met without an additional radiating fin, and the LED is ensured to work in an appropriate temperature range. The utility model has the advantages of simple structure and good effect.
Description
Technical field
The utility model relates to the illuminator field, relate to a kind of with LED (being light emitting diode) as light source, a kind of embedded LED road illuminating lamp that the design of lamp stand, light fixture and pcb board (being printed circuit board (PCB)) is combined as a whole.
Background technology
Along with the continuous progress of LED manufacturing technology, its light efficiency improves constantly, and by the end of at present, the light efficiency of laboratory large power white light LED has surpassed 190lm/W, and the light efficiency of matured product has also reached 90lm/W on the market.This light efficiency value has represented the potentiality of LED in the road lighting field.
Compare with conventional light source, LED has the advantage of a lot of uniquenesses, and is little such as luminous point, be easy to carry out optical design, and Luminaire efficiency can do very highly, therefore compares with conventional light source to have huge energy-saving potential.In addition, the LED life-span is long, and shock resistance is good, the colour rendering index height, and these characteristics all make LED in road lighting is used advantageous advantage be arranged.Though have some LED street lamps to occur now on the market, the design of these street lamps does not have fully to excavate the advantage of LED yet, all there is very big problem in the control aspect of design aspect luminous intensity distribution and junction temperature.
The utility model content
The purpose of this utility model be obtain a kind of simple in structure, luminous intensity distribution rationally, the LED road illuminating lamp of good heat dissipation effect.
The utility model provides a kind of embedded LED road illuminating lamp, is made up of aluminum base PCB plate (being printed circuit board (PCB)), led light source, reflector and street lamp post.Led light source is to be welded on the aluminum base PCB plate, and the overall reflective device is fixed on the aluminum base PCB plate, and the aluminum base PCB plate is fixed on choosing in the arm of street lamp post.
In the utility model, every block of aluminum base PCB onboard led light source has 2-30.
In the utility model, led light source distributes on the aluminum base PCB plate and is parallel 1-4 row.
In the utility model, led light source distribution middle ware is apart from wide, and the both sides spacing is narrow.
In the utility model, described monoblock type reflector has four reflectings surface.
Aluminum base PCB plate in the utility model also can adopt the easy heat sink of other lightweights to replace.
Because the optical design of the LED street lamp that occurs in the market is science not to the utmost mostly, causes actual illuminating effect very poor, the uniformity is very poor on the road, and the zebra effect is very serious.Therefore can not reach the requirement of street illumination lamp on the luminous intensity distribution, and Luminaire efficiency is also very low, can not reach energy-conservation effect.The utility model is designed the overall reflective device that a light that LED can be sent changes into the hot spot of a rectangle through accurate optical design.This reflector is contained in the LED back, so just makes that the illumination on road surface is very even, satisfy the light distribution requirements of road lighting, and improve the utilization rate of light fixture, effectively energy savings greatly.And, with respect to what occur on the present market LED is carried out single luminous intensity distribution, add the mode of Lamp cup exactly in each LED front, this monoblock type reflector is easy for installation, helps large-scale production, also can reduce the cost of reflector greatly.Power of the present utility model can reach 85W, and the high-pressure mercury lamp utilization that can replace traditional 125W fully therefore can be energy-conservation more than 40% on subsidiary road.
Aspect heat dissipation design, traditional LED street lamp generally all adopts the mode of outer radiation fin, and this not only increases the weight of light fixture, has also improved the maintenance difficulties of light fixture.The utility model combines the heat dissipation design and the lamp stand profile of light fixture, and LED is embedded in the lamp stand, makes lamp stand become the radiator of LED, has improved the radiating efficiency of light fixture greatly.The utility model does not need extra radiator, has greatly reduced the weight of light fixture, helps to improve the maintenance factor of light fixture yet.In addition, this integrated design also makes the fitting structure compactness, and is elegant in appearance.
Description of drawings
Fig. 1 is embedded street lamp overall structure figure of the present utility model, and wherein 1 is street lamp post, and 2 choose arm for street lamp, and 5 is the monoblock type reflector.
Fig. 2 is the road lamp profile, wherein 2 chooses arm for street lamp, and 3 is pcb board, and 4 is LED, and 5 is the monoblock type reflector.
Fig. 3 is the pcb board structural representation.Wherein 3 is pcb board, and 4 is LED.
The specific embodiment
The used element of the present invention is as follows:
Street lamp post: be used to install road lamp.
Street lamp is chosen arm: be used to install pcb board, and regulate the street lamp elevation angle.
Pcb board: pcb board adopts aluminium base to utilize it to dispel the heat.
When the utility model is implemented, earlier great power LED is divided into two rows and is welded on the aluminum base PCB plate by spacing commonly used.For helping heat radiation, weld interval, the both sides spacing was narrow apart from being that the middle ware distance is wide.Then the monoblock type reflector is fixed on the aluminum base PCB plate.The monoblock type reflector has four reflectings surface, is aspheric surface, and the light that LED is sent according to ordinary skill in the art means is adjusted into a rectangular light spot, to satisfy the requirement of road lighting.
The instrument assembling process: according to Fig. 1, Fig. 2 assembles, fixing monoblock type reflector on the aluminum base PCB plate that is welded with two row LED, and the pcb board that reflector will be installed at last is fixed on choosing in the arm of lamp stand.
After installing, connecting power supply can throw light on.
