Abstract
The utility model discloses a roadway lighting LED lamp, comprising an aluminum substrate, an LED chip and a gold wire, wherein the gold wire is electrically connected with the LED chip, and the LED chip and the gold wire are installed on the aluminum substrate. The roadway lighting LED lamp is characterized in that the aluminum substrate is provided with a radiator which is in a fin shape, and the aluminum substrate and the radiator are provided with a heat radiating oil layer. In the utility model, heat generated during the work of the roadway lighting LED lamp is mostly concentrated on the aluminum substrate, and heat radiating oil and the radiator are used for emitting out the heat concentrated on the aluminum substrate to the most extent, thereby guaranteeing the service life of the chip.
Description
Technical field
The utility model relates to a kind of LED lamp, is a kind of road lighting LED lamp of good heat dissipation effect specifically.
Background technology
Conventional LED lamp all is to dispel the heat by support, but simultaneously because support will pass through electric current, make the LED lamp like this when work, because the relation of operating current, make support itself will produce certain temperature, even if the material that support adopted how like this, the temperature that the LED lamp produces when work all can not have a strong impact on the life-span of LED lamp timely by the support discharging.And this kind LED lamp is owing to be subjected to the restriction of support, and the lighting angle maximum when the LED lamp is luminous can only be about 130 degree, if be applied in the road lighting, because the restriction of lighting angle makes the illumination of road the black area can occur.Alternative aluminium base all is by screw aluminium base to be fixed on the PCB, the temperature that aluminium base produces when work, just can only outwards discharge by aluminium base or support, but the temperature itself that produces when working owing to the LED lamp just all concentrates on the aluminium base simultaneously, 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 the LED lamp be produced when working emits, and has a strong impact on the life-span of LED.This kind aluminium base is because it is lattice luminous, and the lighting angle maximum of LED can only be about 160 degree, if be applied in the road lighting, because the restriction of lighting angle also can make the illumination of road the black area can occur.
Summary of the invention
The purpose of this utility model provides a kind of road lighting LED lamp of good heat dissipation effect.
The purpose of this utility model is achieved through the following technical solutions:
A kind of road lighting LED lamp comprises aluminium base, led chip and gold thread, and gold thread is electrically connected with led chip, and led chip and gold thread are installed on the aluminium base, it is characterized in that: on the described aluminium base radiator is installed.
Described radiator is the fin shape.
Described aluminium base and radiator are provided with the heat radiation oil reservoir.
The utility model compared with prior art has the following advantages.
The temperature major part that road lighting LED lamp described in the utility model produces when work concentrates on the aluminium base, and by the oily same radiator that dispels the heat, the temperature that will concentrate on the aluminium base emits to greatest extent, guarantees the life-span of chip.
Description of drawings
Fig. 1 is the structural representation of the utility model road lighting LED lamp;
Fig. 2 is the mounting structure schematic diagram of aluminium base and radiator in the utility model road lighting LED lamp.
The specific embodiment
Below in conjunction with accompanying drawing the utility model road lighting LED lamp is described in further detail.
As Fig. 1 and shown in Figure 2, road lighting LED lamp described in the utility model mainly is made up of with heat radiation oil 5 aluminium base 1, led chip 2, gold thread 3, radiator 4.Led chip is installed in the aluminium base bowl cup, by gold thread led chip P knot is coupled together with the N knot, heat radiation oil spreads upon on the radiator, with screw 6 aluminium base is tightened together with radiator at last, adopt distinctive bar shaped bowl cup on the aluminium base simultaneously, the lighting angle of LED is brought up to about 175 degree.Led chip can select 1～8 low-power LED chip also to go here and there arbitrarily, the temperature of generation was dispelled the heat when heat radiation oil was used for led chip work with radiator,, bar shaped bowl cup is used for improving the lighting angle of LED, can not produce the black area when being applied to road lighting to reach the LED lamp.The purpose of this utility model is to guarantee that the work operating temperature that led chip produces when work is lower than 70 °, stablizes the workability of chip, increases the life-span, improves photoelectric transformation efficiency, reduces light decay, increases the lighting angle of LED simultaneously.This LED that is exclusively used in road lighting after tested, light efficiency can reach 120LM/W, uniformity of illuminance＞0.45, the maximum operation temperature when work is no more than 70 °, when being applied to road lighting (lamp that GB requires apart from), road the black area can not occur.
