Description
Technical field
The utility model relates to a kind of street lamp, relates in particular to a kind of LED street lamp.
Background technology
Present lighting adopts incandescent lamp, electricity-saving lamp more, and not only energy-output ratio is big, causes environmental pollution, and light efficiency is low, and heat dispersion is poor.Under the background that the short worry of current global energy raises once again, energy savings is the important problem that we shall face future.Light emitting diode (Light-emitting Diode; Be called for short LED) as a kind of high efficiency light source; Because advantages such as its energy-saving and environmental protection, the life-span is long, volume is little, power consumption is low are widely used in fields such as automobile, traffic lights indication, screen display, illumination.The common LED lamp tool adopts the white point light source to use as radiation source, and scioptics are realized various angle illuminations, the high and manufacturing difficulty to the designing requirement of lens; Such LED light fixture dazzle is serious; The hot spot weak effect, the heat that led chip and fluorescence cover distribute all accumulates on the chip, can't distribute fast; Cause that luminous efficiency is low, radiating effect is poor, can not satisfy user's demand.
The utility model content
In view of the defective that above-mentioned prior art exists, the purpose of the utility model is proposition a kind of anti-dazzle, good heat dissipation effect, the manufacturing is simple, cost is low and the LED street lamp of long service life.
For realizing above-mentioned functions, the utility model adopts following technical scheme:
A kind of LED street lamp; Comprise lamp body led light source reflection shield fluorescence cover drive unit bonnet and support; Said support is provided with lamp body, and said lamp body is provided with led light source, and said bonnet covers on drive unit in the cavity of lamp body rear end; Said fluorescence cover covers said led light source, and said led light source is a blue-light LED chip
Preferably, the diffuser of said fluorescence cover peripheral hardware light-permeable, said diffuser is fixed on the said lamp body.
Preferably, the lamp body that heat conductive metal, plastics or ceramic material are processed but said lamp body is served as reasons.
Preferably, said lamp body is shaped as semicircle half olive shape of wooden dipper shape or half elliptic.
Preferably, said lamp body is rotatably installed on the support.
The utility model is achieved in that the blue led chip is fixed on the aluminium base lamp body; The fluorescence cover covers on the outside of blue led chip; The fluorescence excitation cover was luminous after drive unit made the blue led chip send blue light; The fluorescence cover can be coated the fluorescent material of different formulations as required or evenly manufacture the fluorescence cover behind the mixed fluorescent powder in the raw material the inside, and the light that combines the blue led chip to send then makes whole light fixture send the white light with different-colour and brightness.Adopt said structure; Not only can send white light through blue led chip fluorescence excitation cover with different-colour and brightness, and fluorescent lamp shade conversion light wavelength, the heat of generation can distribute fast; Can not influence the heat radiation of chip conversely; Make that led chip joint temperature is lower, but heat can also be transmitted on the lamp body of processing by heat conductive metal, plastics or ceramic material through aluminium base and be dispersed in the ambient air, radiating effect is more outstanding.
The beneficial effect of the utility model is: the whole light fixture of the utility model can send the white light with different-colour and brightness; And fluorescent lamp shade transforms light wavelength; The heat that produces can distribute fast, can not influence the heat radiation of chip conversely, makes that led chip joint temperature is lower; Heat can also be transmitted to through aluminium base and be dispersed on the lamp body in the ambient air, and radiating effect is outstanding.Scientific and reasonable for structure, manufacture simple, cost is low, whole artistry is good, long service life, anti-dazzle, light efficiency is good and radiating effect is given prominence to.
Description of drawings
Fig. 1 is the perspective view of the utility model embodiment decomposing state;
Fig. 2 is the cross-sectional view of the utility model embodiment.
Among the figure: 1-lamp body, 2-LED light source, 3-reflection shield, 4-fluorescence cover, 5-drive unit, 6-bonnet, 7-support, 8-diffuser.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the utility model is done further detailed description, so that the utility model technical scheme is easier to understand, grasp.
Like Fig. 1, shown in 2, the utility model provides a kind of LED street lamp, comprises lamp body 1, led light source 2, reflection shield 3, fluorescence cover 4, drive unit 5, bonnet 6 and support 7; Said support 7 is provided with lamp body 1; Said lamp body 1 is provided with led light source 2, and said bonnet 6 covers on drive unit 5 in the cavity of lamp body 1 rear end, and said fluorescence cover 4 covers said led light source 2; Said led light source 2 is a blue-light LED chip, can excite said fluorescence cover 4 to send the white light with different-colour and brightness.
Particularly; The blue led chip of led light source 2 is fixed on the aluminium base lamp body 1; Fluorescence cover 4 covers on the outside of blue led chip, and fluorescence excitation cover 4 was luminous after drive unit 5 made the blue led chip send blue light, and fluorescence cover 4 can be coated the fluorescent material of different formulations as required or evenly manufacture the fluorescence cover behind the mixed fluorescent powder in the raw material the inside; The light that combines the blue led chip to send then makes whole light fixture send the white light with different-colour and brightness; Simultaneously; Fluorescent lamp shade transforms light wavelength, and the heat of generation can distribute fast, can not influence the heat radiation of chip conversely; Make that the joint temperature of chip is lower; But the heat that produces can also be transmitted on the lamp body of being processed by heat conductive metal, plastics or ceramic material 1 through aluminium base and be dispersed in the ambient air, and radiating effect is more outstanding and obvious, can prolong the service life of light fixture.
Especially, outside that can also fluorescence cover 4 is set up diffuser 8 and is fixed on the said lamp body 1, so that the led light source 2, fluorescence cover 4 and other elements that protect better in the lamp body 1 are not damaged.Led light source 2 adopts large-power LED light beads, than the led light source assembly of modularity design manufacture more easy, cost is lower.The shape of lamp body 1 adopts shapes such as wooden dipper shape, semicircle, half olive shape or half elliptic; Be rotatably installed on the support 7; Can adjust the irradiating angle of light fixture according to actual needs, reduce dazzle effectively, increase the irradiation of object vertical plane; Improve recognition capability, be particularly suitable for outdoor lighting and use.
The beneficial effect of present embodiment is: scientific and reasonable for structure, manufacture simple, cost is low, whole artistry is good, long service life, anti-dazzle, light efficiency is good and radiating effect is given prominence to.
Should be noted that at last that obviously those skilled in the art can carry out various changes and modification to this patent and not break away from the spirit and scope of the present invention.Like this, if these of this patent are revised and modification belongs within the scope of this patent claim and equivalent technologies thereof, then this patent also is intended to comprise these changes and modification.
