Abstract
The utility model relates to an energy-saving LED street lamp. The energy-saving LED street lamp comprises a lamp pole and a lamp cap mounted on the lamp pole, wherein the lamp cap consists of a lens, a tough-shaped heat dissipation housing, an LED lamp, a printed circuit board and a metal substrate, wherein the lens is matched with the tough-shaped heat dissipation housing; the metal substrate is fixed in the tough-shaped heat dissipation housing; the printed circuit board is fixed on the metal substrate; the LED lamp is fixed on the printed circuit board; and an insulation layer is arranged between the metal substrate and the printed circuit board. Through the elaborate optical structure design and perfect light distribution curve, the energy-saving LED street lamp can form a rectangle-like elliptical light spot is formed in an optical domain. The lens can enhance the utilization rate of the light source for illumination and can obviate the dark areas between the conventional street lamps, thereby ensuring safe and conform driving at night. The adoption of a lens with light form transformation and polarization function can reduce the height of the lamp pole as well as the power of the LED light source, thereby lowering the construction cost and use cost of the street lamp.
Description
Technical field
The utility model relates to a kind of lighting device, especially LED energy-saving road illuminating lamp.
Background technology
Street lamp has become an indispensable part in people's life, and bring great convenience to pedestrian and vehicle night.What now be most widely used is high-pressure mercury lamp, though its better performances, but still have certain problem.Sodium vapor lamp is in when illumination heating, has most electric energy to be converted to heat energy and lost, and only has small part to be used for illumination, wasted the energy greatly; Irradiation angle and direction that sodium vapor lamp sends are wayward, and the road surface of being everlasting forms the shadow area, influences driving at night; Sodium vapor lamp needs the high voltage startup bulb when starting, exist hidden danger and response time long; Be 1 year the average life of sodium vapor lamp in addition, and service life is short, the operating cost height.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of efficient, safety, energy-saving and environmental protection, the life-span is long, response speed is fast LED energy-saving road illuminating lamp are provided.
LED energy-saving road illuminating lamp of the present utility model, be that the lamp holder formation has been installed on lamp stand, lamp holder is to be made of lens, flute profile heat-dissipating casing, LED lamp, printed circuit board (PCB) and metal substrate, described lens match with the flute profile heat-dissipating casing, in the flute profile heat-dissipating casing, be fixed with metal substrate, at the metal substrate fixed printed circuit board, the LED lamp is fixed on the printed circuit board (PCB), is provided with insulating barrier between metal substrate and printed circuit board (PCB).
As further improvement of the utility model, on printed circuit board (PCB), be coated with thermal grease.
As further improvement of the utility model, be coated with thermal grease in the inboard of heat-dissipating casing.
The utility model LED energy-saving road illuminating lamp: outward appearance is frivolous, can effectively reduce windage, alleviates the load of lamp stand, strengthens safety coefficient.The led light source irradiating angle can design as required, promptly reduces dazzle and light pollution, can improve the effective rate of utilization of light again greatly.Operating voltage is low can not to cause the lampshade blackout because of high pressure adsorbs dust as common street lamp, safe and reliable; Operating temperature is low, and led light source belongs to cold light source, dispels the heat when good, and its operating temperature is lower than 60 ∩, can not cause the aging jaundice of lampshade; Start and do not have time-delay.Energising promptly reaches normal brightness, need not to wait for, has eliminated conventional road lamp long and problem that start repeatedly start-up time.Pure DC operation has been eliminated the visual fatigue that the conventional road lamp stroboscopic causes.Shock-resistant, seismic force is strong, and no filament and glass shell do not have the cracked problem of traditional light.Wide input voltage, the PWM constant current technology, the efficient height, heat is low, the constant current accuracy height.LED issues the efficient 75-100lm/w of bright dipping at existence conditions.This road lamp energy-saving effect is obvious, compares with traditional high-pressure mercury lamp street lamp, is obtaining under the identical road illumination prerequisite, and saves energy is more than 50%.
The utility model LED energy-saving road illuminating lamp: by meticulous optical texture design, perfectly the light source distribution curve flux allows the illumination light territory form approximate rectangular ellipse light spot.Adopt lens to improve the utilization rate at road lighting of light source, avoid dark area between lamp that conventional street lamp forms and the lamp, nighttime driving is safer, comfortable.Employing has the lens of light fractal transform and polarisation function, with reducing the height of street lamp post and the power of led light source, reduces street lamp construction cost and use cost.
Description of drawings
Figure of description is a structural representation of the present utility model.
The specific embodiment
LED energy-saving road illuminating lamp of the present utility model, be lamp holder 1 to be installed constitute on lamp stand, described lamp holder 1 is to be made of lens 2, flute profile heat-dissipating casing 3, LED lamp 4, printed circuit board (PCB) 5 and metal substrate 6, described lens 2 match with flute profile heat-dissipating casing 3, in flute profile heat-dissipating casing 3, be fixed with metal substrate 6, at metal substrate 6 fixed printed circuit boards 5, LED lamp 4 is fixed on the printed circuit board (PCB) 5, is provided with insulating barrier 7 at metal substrate 6 and 5 of printed circuit board (PCB)s.Wherein, on printed circuit board (PCB), be coated with thermal grease 8, be coated with thermal grease 9 in the inboard of heat-dissipating casing 3.Thermal grease and aluminium base form good insulation effect, guarantee the security of light source.The adapted heat-dissipating casing is well accomplished heat sinking function simultaneously, makes circuit significantly reduce the temperature loss.Heat-dissipating casing adopts aluminum material to make, surperficial pure polyester thermosetting powder spraying, and lens have been adopted safety glass and have been made, and seal with silica gel strip at the two contact-making surface.
LED energy-saving road illuminating lamp of the present utility model, adopt import CREE great power LED as light source, internal work is a constant current source power supply, the novel energy-conserving light fixture of outside wide voltage input AC85-264V, in the spectrum that LED produced, not having ultraviolet ray, infrared ray, heat and radiation, is typical green illumination light source.Have good light transmittance and dustproof and water resistance, light fixture itself has good self-cleaning, has safe and reliablely, and power consumption is low, characteristics such as long service life.According to LED single-point light source installation flexibility, by branch, subangle method is installed, solve the effective area that spectrum covers very perfectly, and reached the even distribution of light, no shadow occurs between bar and the bar.The material of product is easily purchased, and technological process is simple, and the technology of each procedure is easy to grasp.
