Abstract
The utility model provides a dimmable LED street lamp, which comprises a lamp cap mounted on a lamp stem, the lamp cap comprises a radiating lamp housing and mass LED lamps mounted in the radiating lamp housing, an LED lamp mounting plate is fixed in the lamp housing, and a plurality of planes with different angles are arranged on the plate; and the LED lamps are fixed in each plane of the LED lamp mounting plate through a plurality of plane aluminum base PCBs. The utility model has the advantages that: planes with different angles can be processed on the LED lamp mounting plate for changing the arrangement of the LED lamps, and break angles of the processed planes can be changed flexibly according to the space and the height of the lamp stem and the width of roadway, thereby adjusting the illumination range, reducing the die sinking and saving costs, and the street lamp is fast in heat conducting, and can be better applied in urban construction.
Description
(1) technical field
The utility model belongs to street lamp, particularly a kind of Dimmable LED street lamp.
(2) background technology
Along with the fast development of China's economic construction, the LED road lamp has obtained general promotion and application.Some defectives in the LED lighting process also slowly highlight.Tradition LED light emitting diode is installed in the fixing plane, the rising angle of white light emitting diode is generally between 30 °-140 °, because the restriction at the single and luminous angle on plane, cause the illumination beam below the street lamp strong excessively, and all the other local illumination deficiencies cause speck or blanking bar, uneven illumination to spare.The LED broken line mounting technique of Chan Shenging improved to some extent than it afterwards, it is that the LED Light-Emitting Diode is fixed in the several planes that form knuckle, the LED illumination zone has had certain expansion, but this die casting light fixture has very big drawback, it only is applicable to a kind of lamp stand spacing, pole height, width of roadway, in case lamp stand spacing, pole height, width of roadway change to some extent, still can cause blanking bar owing to illumination range is limited.In this case, knuckle will be adjusted change, so light fixture again die sinking carry out the die casting manufacturing, because of mould take expensive, thereby cause the raising of production cost.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide that a kind of illumination range is adjustable, illumination evenly, save the Dimmable LED street lamp of cost.
The utility model is achieved by the following technical solution:
Dimmable LED street lamp of the present utility model, comprise be installed on the lamp stand lamp holder, lamp holder comprises heat-dissipation lamp housing, is installed in a large amount of LED lamp in the heat-dissipation lamp housing, and its special character is: be fixed with LED lamp installing plate in the lamp housing, this plate is provided with the plane of several different angles; The LED lamp is fixed in each plane of LED lamp installing plate by several plane aluminum base PCB plates.
The beneficial effects of the utility model are, can change the layout of LED lamp by the plane of processing different angles on LED lamp installing plate, the plane knuckle that can come flexible transformation to process according to the change of lamp stand spacing, pole height, width of roadway, thereby adjusting illumination range, improved illumination uniformity by light regulating technology, reduce die sinking, save cost, heat conduction is rapid.It is not to realize the expansion of illumination range by improving power, but original strong beam is evenly scatter by light modulation, reaches better illuminating effect, therefore can be applied in the urban construction better.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model integral body, and Fig. 2 is the A-A sectional structure schematic diagram of lamp holder, and Fig. 3 is the lamp holder principle schematic.
Among the figure, 1 lamp holder, 2 heat-dissipation lamp housings, 3LED lamp installing plate, 4LED lamp, 5 plane aluminum base PCB plates; A, β are adjacent two plane knuckles on the LED lamp installing plate, the angle of the vertical line on promptly adjacent two planes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Dimmable LED street lamp of the present utility model, comprise be installed on the lamp stand lamp holder 1, lamp holder comprises heat-dissipation lamp housing 2, is installed in a large amount of LED lamp 4 in the heat-dissipation lamp housing, and its special character is: be fixed with LED lamp installing plate 3 in the lamp housing, this plate is provided with the plane of several different angles; LED lamp 4 is fixed in each plane of LED lamp installing plate by several plane aluminum base PCB plates 5.Two adjacent on the LED lamp installing plate 3 plane knuckles are a, β, and knuckle a and β are according to pole height, lamp stand spacing, the difference of having a lot of social connections and corresponding the variation.
Fig. 1 is the structural representation of the utility model integral body, and Fig. 2 is the A-A sectional structure schematic diagram of lamp holder.Heat-dissipation lamp housing 2 is made of aluminum, and LED lamp installing plate 3 is parts of aluminium matter geometry entity, and casting forms.Lamp holder 1 increases a LED lamp installing plate 3 on original single plane base, as required, process the plane of several different angles on LED lamp installing plate; LED lamp 4 is welded on the aluminum base PCB plate of plane, plane aluminum base PCB plate 5 is fixed in several planes of LED lamp installing plate 3 by heat-conducting glue, so just the strong beam that concentrates under the single plane has been distributed under the Different Plane, improved the uniformity of illumination by light modulation, be in the light that the LED lamp 4 in the Different Plane sends and also expanded illumination range (seeing accompanying drawing three).In case lamp stand spacing, pole height, the change to some extent of having a lot of social connections can be reselected the LED lamp installing plate 3 that share, and change illumination range easily, do not need die sinking again.Simultaneously, by LED lamp installing plate 3, the heat energy that the LED lamp produces is sent to aluminum heat-dissipation lamp housing 2 outer surfaces, and these heat energy flow by air and are dispersed into rapidly in the atmosphere, have good thermal diffusivity.
Claims (1)
1. Dimmable LED street lamp, comprise be installed on the lamp stand lamp holder (1), lamp holder comprises heat-dissipation lamp housing (2), is installed in a large amount of LED lamp (4) in the heat-dissipation lamp housing, and it is characterized in that: be fixed with LED lamp installing plate (3) in the lamp housing, this plate is provided with the plane of several different angles; LED lamp (4) is fixed in each plane of LED lamp installing plate by several plane aluminum base PCB plates (5).
