Abstract
The utility model discloses a solar LED streetlamp, which can meet the heat dissipation requirement of an LED streetlamp, is light in deadweight, reduces the light attenuation of an LED light source and prolongs the service life of the LED streetlamp. The solar LED streetlamp mainly comprises a solar battery assembly, an LED lamp body, a control cabinet and a lamppost, wherein the LED lamp body includes an upper casing, a lower casing, a heat sink, an LED light source, and a constant current source; a platform matched with the heat sink and arranged on the upper casing is used for mounting the heat sink; most of the bottom surface, contacted with the heat sink, of the platform, is gouged out, and is used for mounting the LED light source and the constant current source on the heat sink; an aluminum base is further additionally mounted between the LED light source and the heat sink; and the platform is provided with a water outgoing groove.
Description
Technical field
The utility model relates to a kind of road lamp device, is specifically related to a kind of solar LED illuminating street lamp.
Background technology
Along with the poorness day by day of earth resource, the cost of investment of basic energy resource is climbed to a higher point day by day, and solar energy is more and more paid attention to as safety, the environmental protection new forms of energy of a kind of " inexhaustible, nexhaustible ".Simultaneously; Also along with the development and progress of solar-photovoltaic technology; The solar energy lamp product is in the double dominant of environmental protection and energy saving, and the application of aspects such as solar street light, garden lamp, Lawn lamp has formed scale gradually, and solar electrical energy generation is gradually improved in the field of street lamp lighting development.
The heat that is produced during led light source work accounts for it and consumes about 70% of general power, and the heat that is produced when it is luminous will make too high, the increase light decay of LED knot surface temperature, and then influence product life cycle, luminous efficiency, stability if can't derive.High-power LED street lamp adopts Birmasil that fin and lamp housing are cast as one at present; Because the Birmasil conductivity of heat is good inadequately, it is not ideal enough to dispel the heat, and satisfy heat radiation and require then must strengthen its weight; Cause that this lamp housing weight is big, cost is high, also give to set up to install to wait and cause difficulty.
The utility model content
The utility model technical problem to be solved provides a kind of solar LED street lamp, and it can satisfy the heat radiation requirement of LED street lamp, and own wt is light, reduces the light decay of led light source, prolongs the life-span of LED street lamp.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of solar LED street lamp; Mainly be made up of solar module, LED lamp body, control cabinet and lamp stand, wherein the LED lamp body comprises upper shell, lower house, radiator, led light source, constant-current source, said upper shell have with the adaptive platform of radiator in order to radiator to be installed; The bottom surface major part that this platform contacts with radiator is cut out; In order to led light source, constant-current source to be installed on radiator, also install aluminium base between said led light source and the radiator additional, this platform is provided with effluent trough.
The beneficial effect of the utility model is, radiator exposes from upper shell, and its permeability is good; Strengthened radiating effect, and aluminium section bar radiator heat-dissipation effect is better than Birmasil, under 25 ℃ of situation of environment temperature; The utility model chip substrate maximum temperature of light source power 100W has only 54 ℃, than low 10 ℃ of the similar street lamp of pure Birmasil, the chip substrate temperature of high-power LED street lamp is reduced greatly; Reduce the light decay of high-power LED light source, prolong the high-power LED light source life-span.
Description of drawings
Fig. 1 is the structure chart of LED lamp body in the utility model, and Fig. 2 is the vertical view of Fig. 1.
Among the figure: upper shell 1 lower house 2 radiators 3 constant-current sources 4 reflection shields 5 pedestal 6LED light sources 7 rubber seal 8 cloches 9 effluent troughs 10
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
Like Fig. 1, shown in Figure 2; Upper shell 1 top has one to be used for installing radiator 3 with radiator 3 suitable platforms, and the major part of the bottom surface that this platform contacts with radiator 3 is cut out, and is convenient on radiator 3, install led light source 7 and constant-current source 4 like this; Also install aluminium base 6 additional between said led light source 7 and the radiator 3; Also leave the effluent trough 10 into design of Platform on the housing, distributed flow tank around the platform is used for the sleet that drops on the radiator 3 is drawn.
