The specific embodiment
As shown in the figure, the utility model can respectively be installed 1-10 separate unit, is equipped with end cap according to the two ends of making up big small lamp afterwards, and fitting structure forms a whole.The light source of light fixture adopts power-type LED luminous tube 8, and the LED luminous tube is welded on the aluminium base 4 with heat sinking function, and surperficial embedding software silica gel 5, software silica gel top is provided with stainless steel reflector 9.The centre of light fixture also is furnished with the power-type LED luminous tube that two row have optical lens 6, is used for replenishing illumination.
The shell of light fixture is a protective cover, also is the heat abstractor of overlarge area.The centre of main part is a lamp stand installing hole 3.
The utility model advantage is:
1. there is not the glass protecting cover
This Novel LED street lamp has been abandoned conventional road lamp and the mentality of designing of LED street lamp in the past, the glass of front end The glass protective cover removes, the be up to state standards degree of protection requirement of regulation of the embedding by software silicon rubber 5. It has been reduced by the glass protecting cover block the light loss that causes, through test together with the glass protecting cover relatively Light efficiency has improved 30%.
2. has reflection unit
Be provided with stainless steel reflector 9, the LED luminous tube above the utility model light-emitting area software silicon rubber The light that sends is except the light intensity direction, and the light of other angle and veiling glare are by being radiated at the stainless steel reflector Rear formation reflection is got light having added on the light intensity direction again to reflection light secondary afterwards, thereby Reduce light loss, improved the light utilization efficiency of LED street lamp.
3. the adjustable secondary optical design of light-emitting area curvature
Trunk portion of the present utility model and separate unit, installation splicing adjustable angle between separate unit and the separate unit, thereby realize the adjustable of street lamp light-emitting area curvature, reach flexible adjustment light distribution curve, solve poor, the dazzle value height of illumination uniformity, thereby improved light utilization efficiency, the adaptive capacity of raising differing heights lamp stand, the adaptive capacity of the different road types of raising.As Fig. 2-shown in Figure 5, can be according to the throw light on requirement of standard of different types of road, the lamp luminescence curvature of face is adjusted, make light distribution curve, road lighting uniformity, the dazzle value of LED street lamp possess adjustable, to meet different pole height, different types of road illumination code requirement.The scope of application has expanded the tunnel traffic lighting field to.
4. optical lens device further improves the uniformity of LED street lamp, the led light source that two row are equipped with the optical concentration lens is equipped with in central authorities of the present utility model, optically focused effect by optical lens, replenish road irradiation breadth edge illumination with the LED light that strengthens, solve the homogeneity question of road lighting.
5. maintainable
The utility model has solved the not maintainable of other LED street lamp product, and this product is partly to be combined by light fixture trunk portion and separate unit, has characteristics such as detachable, replaceable.Can fetch maintenance to wherein fault led light source place separate unit replacing if any fault, installation and maintenance are easy.Solved LED street lamp product integral replacing maintenance in the past, maintenance workload reduces greatly, has also reduced the maintenance cost of payment for this reason, thereby has reduced the potentiality of interruption of communication, broken the not maintainable of LED street lamp.
6. the extensibility of flexible configurations
Lamp body of the present utility model is partly to be combined by light fixture trunk portion and separate unit, and the both wings of trunk portion are spliced and combined by several separate units and form, and 1-10 separate unit can respectively be installed form different capacity size, the light fixture of different apparent sizes.
Therefore realized having reached the adjustability of lamp power, broken conventional road lamp and other LED street lamp product fixed dimension, power, light-emitting area curvature isotype, reached the effect that enlarges application by configuration.
7. permanent protective property
(1) waterproof, winter protection, anti-cracking, LED street lamp product in the past is only in outer cover interface adhesive tape sealing, inner LED and circuit part all expose, because day and night temperature is big, the termination of outer cover is expanded with heat and contract with cold different with outer cover, cause sealing joint strip the slit to occur, the back rainwater that rains will infilter inside and cause short circuit to damage light fixture.
(2) the utility model is handled internal circuit and the special software silicon rubber embedding of the whole employing of LED, only expose the LED luminous component, the special software silica gel that is adopted has good anti-low temperature, waterproof, anti-cracking, antiacid, alkali resistant, antimycotic characteristic, also ability hygrothermal environment and anti-multiple grease, the applied environment temperature range :-60 ℃ to+180 ℃ is that light fixture is applicable to north cold area.
(3) electric cable, conventional wire cable and plastic connector are selected by a lot of producers, perhaps select second-rate metal joint, the test of short time and use, plastic cement can not be out of shape, and waterproof is no problem.But irradiation and day and night temperature through the sun change, four seasons climate change, and plastic cement will be out of shape, thereby cause waterproof apron to lose efficacy, rainwater infilters joint inside and causes wire short-circuiting, and especially at electriferous state, the corrosion of electric wire is done an order of magnitude than high inviting under the electriferous state not.Because problem of materials own is also corroded by rainwater easily, causes signal shorts.
All adopt the rubber lead, the utility model all adopts silicon rubber insulation lead and joint as power supply and control signal cable, installs in order to the wiring of product.This cable has good anti-low temperature, and waterproof is antiacid, alkali resistant, and antimycotic characteristic, ability hygrothermal environment and anti-multiple grease, the Applicable temperature scope is big.
8. heat dissipation problem
(1) there is not cover
From the above mentioned, the utility model light-emitting area adopts embedding silica gel technology, has solved the low problem of protective, and degree of protection reaches IP67.So the glass protecting cover that has removed lamp surface that this product is bold more helps the natural convection air heat radiation, heat is imported in the atmosphere apace go, and then the radiating effect of light fixture is improved thereupon.
(2) super large area of dissipation
The utility model has been designed and developed aluminium section bar that upside has radiating fin as lampshade, and whole lamp body formed a big radiator structure.Because the lighter weight of aluminium and thermal conductivity factor height, can effectively internal heat be derived, therefore using aluminium section bar is better solution, when design aluminium base is tried one's best near the aluminium section bar lamp body in addition, improve radiating efficiency, thereby reduce the thermal resistance that casting glue partly produces.
The utility model adopts anti-low temperature, waterproof, and anti-cracking, antiacid, alkali resistant, the software silica gel of antifungal property are potted in the degree of protection that has reached IP67 under the prerequisite that light-emitting area do not use cover plate, and institute is so that radiating effect improves greatly.Show that through degradation the heat dissipation design that this light fixture is good has reduced thermal resistance, reduced light decay, the life-span of light fixture is prolonged greatly, also be equivalent to 50 times of conventional incandescent.The utility model environmental protection, no poisonous metal mercury, spectrum does not contain infrared and ultraviolet.
