Abstract
The utility model relates to the filed of LED lighting apparatuses, in particular to an LED used for road illumination, wherein a chip (5) is installed in a bowl of an aluminum base plate (1), the P joint and the N joint of the chip (5) are connected through a gold thread (6), the lower side of the aluminum base plate (1) is provided with a radiator (3), and radiating oil (2) is coated between the aluminum base plate (1) and the radiator (3). The LED used for road illumination has the advantages of excellent heat radiating effect, long service life, big light-emitting angle and little black area.
Description
Technical field
The utility model relates to LED lighting apparatus field, relates in particular to a kind of LED that is used for road lighting.
Background technology
Energy shortage is the hot issue of the world today, and in illuminating industry, the LED light emitting diode is because multiple advantages such as its efficient, energy-saving and environmental protection, long-life are to replace the energy consumption height, the first-selection of the traditional lighting that the life-span is short.The LED heat radiation generally is divided into two kinds, a kind of is logical support heat radiation, because support will pass through electric current, make LED support when work itself will produce certain temperature like this, the temperature that LED produces when work can not have a strong impact on the life-span of LED timely by the support discharging, and the LED of this structure is owing to be subjected to the restriction of support, lighting angle maximum when luminous can only be applied in the road lighting because the restriction of lighting angle makes the illumination of road certain black area can occur about 130 degree.Another kind is to adopt the aluminium base heat radiation, by screw aluminium base is fixed on the PCB, and the temperature that aluminium base produces when work is outwards discharged by aluminium base or support.Because the temperature itself that LED produces when work just all concentrates on the aluminium base, even if the coefficient of heat transfer of the material aluminium that aluminium base uses is than higher, but the temperature that can not timely LED be produced when working emits, thereby influence the service life of LED, existing aluminium base is lattice luminous, the lighting angle maximum of LED can only be applied in the road lighting because the restriction of lighting angle also can make the illumination of road certain black area can occur about 160 degree.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the technical deficiency that the existing LED that is used for road lighting exists, and a kind of perfect heat-dissipating, the LED that is used for road lighting that lighting angle is big are provided.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of LED that is used for road lighting, chip are installed in the bowl cup of aluminium base, and the P knot of chip links to each other by gold thread with the N knot, and described aluminium base below is provided with radiator, scribbles heat radiation oil between aluminium base and the radiator.The temperature major part that LED produces when work concentrates on the aluminium base, and the temperature that will concentrate on the aluminium base to greatest extent by dispel the heat oil and radiator emits, and has guaranteed the service life of chip.
As preferably, described heat radiation oil spreads upon on the radiator end face, and the aluminium base end face is provided with bar shaped bowl cup.Bar shaped bowl cup can be brought up to the lighting angle of LED about 175 degree, can effectively improve the lighting angle of LED, is used for the black area that the LED of road lighting exists with minimizing.
As preferably, described aluminium base and radiator are fixed by screw.
As preferably, described radiator is an aluminium sheet, and the aluminium sheet bottom is provided with a plurality of radiating grooves, and radiating effect is better.
A kind of LED that is used for road lighting by the technical solution of the utility model design, heat radiation oil and radiator can make LED effective, bar shaped bowl cup can improve the lighting angle of LED, in sum, this LED that is used for road lighting has good heat dissipation effect, long service life, and lighting angle is big, have the few advantage in black area.
Description of drawings
Fig. 1: the structural representation of the utility model embodiment.
Fig. 2: the A-A cutaway view among Fig. 1.
The specific embodiment
Be described further below in conjunction with accompanying drawing 1, Fig. 2 the utility model.
A kind of LED that is used for road lighting as shown in Figure 1 and Figure 2, chip 5 are installed in the bowl cup of aluminium base 1, and the P knot of chip 5 links to each other by gold thread 6 with the N knot.Aluminium base 1 below is provided with radiator 3, and aluminium base 1 and radiator 3 are fixing by screw 4, scribbles heat radiation oil 2 between aluminium base 1 and the radiator 3.Radiator 3 is aluminium sheets, and the aluminium sheet bottom is provided with a plurality of radiating grooves 8, and heat radiation oil 2 spreads upon on the end face of aluminium sheet, and heat radiation oil 2 is heat-conducting silicone greases.The temperature that produces during led chip 5 work is lower than 70 °, stablize of chip 5, and long service life improves photoelectric transformation efficiency, the minimizing light decay.After tested, light efficiency can reach 120LM/W. uniformity of illuminance＞0.45.Aluminium base 1 end face is provided with 3 bar shaped bowl cups 7, make light that led chip produces in when work through the control of bar shaped bowl cup, make light spread, the lighting angle of LED is brought up to about 175 degree to both sides, when being applied to road lighting (the lamp distance that GB requires), road the black area can not occur.
The foregoing description only is a better embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
