Description
Technical field
The present invention relates to the application of great power LED aspect semiconductor lighting, particularly high-power LED street lamp belongs to field of semiconductor illumination.
Background technology
The main light source of conventional road lamp light fixture is Metal halogen lamp, fluorescent lamp, and these light source volumes are big, and electric wiring is simple, and is high temperature resistant, so the conventional lamp volume is big, heat dispersion is poor.Along with development of semiconductor and GaN great power LED are succeeded in developing, LED has obtained at aspects such as signal demonstration, back lighting, Landscape Lightings using widely as semiconductor light sources in recent years.Be accompanied by high power white light the LED light efficiency improve constantly development with the high-power LED encapsulation technology, semiconductor light sources begins progressively to be applied to the white-light illuminating field.Semiconductor lighting has characteristics such as energy-saving and environmental protection, light source high life, is called as the third generation lighting source after lightings such as incandescent lamp, fluorescent lamp.But, semiconductor light sources, volume is little, the electric appliance circuits complexity, non-refractory, combine difficulty with the conventional road lamp light fixture, the semiconductor LED light source applications belongs to the concrete application of LED white light outdoor lighting aspect street lighting, and high-power LED light source requires to be operated in the working environment with good performance of heat dissipation.The led light source light distribution angle is more concentrated in addition, need luminously carry out secondary optics design to it, avoids semiconductor road lamp luminous too concentrated.Therefore, traditional fitting structure can not adapt to the instructions for use of led light source.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of high-power LED street lamp is provided, solved the heat dissipation problem of the light source in the LED street lamp and the light of LED street lamp is evenly distributed, reached the requirement of outdoor lighting.
Technical scheme of the present invention is as follows:
A kind of high-power LED street lamp, comprise lamp body, at least one group of led light source and LED radiating piece, be used for the metal pcb board that the led light source circuit connects, it is characterized in that described metal pcb board is fixed on the lamp body, it is provided with at least one hole, described LED radiating piece is installed in the hole, and the main body of described LED radiating piece is a metal cartridge, and its bottom is a plate-like, be fixed on the lamp body rear inner surface, the top of LED radiating piece is connected with led light source.
Among the present invention, LED radiating piece top is preferably with gradient, and is provided with pad.The bottom of LED radiating piece preferably can closely be connected on the lamp body rear inner surface by heat-conducting glue.The LED radiating piece can be made of copper.
Metal pcb board of the present invention surface preferably is coated with protective plate.
Lamp body of the present invention front portion should be provided with optical transmission window, and the lamp body external rear face is preferably with radiating fin or heat radiation cylinder.The lamp body rear portion can be made by cast aluminium.
The present invention is by fin-shaped or column fin on LED radiating piece and the lamp body, solved the heat dissipation problem of LED street lamp, improve the semiconductor light sources radiating effect, the power-type LED in the street lamp is worked in the ambient temperature range that allows, improved the reliability of high-power LED street lamp.Adjust the light direction of LED by the different gradients at LED radiating piece top, make the LED street lamp have good light and distribute.In addition, it is simple that the present invention also has optical design, and assembling is easy to characteristics.

Fig. 2 is the vertical view of the radiating piece in the high-power LED street lamp of the present invention;
Fig. 3 is the front view of the radiating piece in the high-power LED street lamp of the present invention.
Number in the figure: 1 pad; 2 pins; 3 exposed metals; The 4LED light source; The 5LED radiating piece; 6 metal pcb boards; 7 protective plates; 8 copper washers; 9 lamp bodies; 10 optical transmission windows.
The specific embodiment
Below in conjunction with accompanying drawing and example explanation embodiment of the present invention, as shown in Figure 1, lamp body 9 is divided into rear portion and front portion, and external rear face is manufactured with the fin-shaped radiator structure, also can be made into column radiator structure (not drawing among the figure).Lamp body 9 rear portions and fin-shaped fin are the cast aluminium material, and the inner surface at lamp body 9 rear portions is smooth, can closely be connected with the LED radiating piece, scribble heat-conducting glue therebetween so that radiating piece heat conduction.The lamp body 9 anterior safety glass that adopt are as optical transmission window 10.
A road lamp body interior 9 can be by a plurality of LED radiating pieces 5 and led light source 4, the led light source 4 that is positioned on the LED radiating piece 5 is connected by metal pcb board 6, and leave circular hole on the metal pcb board 6, make LED radiating piece copper post 12 be positioned at pcb board 6 tops corresponding to LED radiating piece 4.Pcb board 6 is fixed on lamp body 9 inner surfaces by screw, between screw and the lamp body 9 by with the copper washer 8 of LED radiating piece chassis 11 consistency of thickness.LED radiating piece 5 adopts the fine copper material, and its top distributes according to not sharing the same light of street lamp and requires to adopt different gradients.LED radiating piece 5 and led light source 4 closely are connected on the inner surface at lamp body 9 rear portions by heat-conducting glue.
The structure of LED radiating piece as shown in Figures 2 and 3, two Semicircular pads 1 are arranged at the top of copper post 12, are used for welding led light source 4, between pad 1 and the copper post 12 insulating barrier are arranged, the label 3 among Fig. 2 refers to the bare metal part at LED radiating piece top.Pad 12 1 ends have pin 2 to draw, and are used for being connected on the pcb board 6.
Need to prove, here the detailed explanation that has been center deployment with embodiments of the invention, the imbody of described optimal way or some characteristic, should be understood to this specification only is to describe invention by the mode that provides embodiment, in fact on some details of structure and preparation method and use, can change to some extent, for example, the size of LED heat spreader structure, shape can change accordingly according to the different size of the led light source that uses.The shape of lamp body fin can be fin-shaped, heat radiation column etc.These distortion and application all should belong in the scope of the present invention.
