Description

High-power LED street lamp
Technical field
The utility model relates to led light source, the integrated encapsulation street lamp of especially a kind of great power LED.
Technical background
Conventional road lamp has incandescent lamp, high-pressure mercury lamp, has occurred a plurality of great power LEDs in recent years and has been the light source that matrix is arranged.The lighting angle of sodium vapor lamp fluorescent tube is 360 °, and is general, need be by just shining the appointed area after the reflector reflection, and bulb structure has determined that the light source utilization rate of light fixture is low, the light source utilization rate of sodium vapor lamp only has 40%.And the colour temperature of sodium vapor lamp and video picture index are all lower, and it is yellow that glow color is, and sodium vapor lamp belongs to thermal light source, and sodium vapor lamp needs five to ten minutes preheating time from being opened to normal luminosity.The tradition sodium vapor lamp produces gas and luminous with high voltage, and mode of operation has determined that the life-span of high-pressure mercury lamp is shorter.A plurality of great power LEDs are has increased cost as illuminator after matrix is arranged, and is not easy to obtain needed projected spot.
Summary of the invention:
The technical problems to be solved in the utility model provides the high-power LED street lamp of a kind of good heat dissipation effect, luminous efficiency height, long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of high-power LED street lamp, comprise led light source, lens, lampshade, radiator, driving power and shell, this led light source adopts the great power LED integrated encapsulation structure, and this led light source comprises radiating block, is installed on the annular matrix in radiating block front, is positioned at the led chip that the matrix looping pit is installed on the radiating block front.
Described led light source, lens, lampshade are fixed on the radiator in proper order, and the lampshade cover lens, and lens cap led light source, constitute totally-enclosed integral LED illuminator.
Described radiator is the cuboid framework, and the vertical section of this radiator is a flute profile, and the horizonal base plate of this flute profile radiator is provided with some louvres and fin, and these some fin are positioned at this horizontal base edges of boards portion both sides perpendicular to this horizonal base plate.
Described led light source is fixed on the radiator and is meant, the radiating block of this led light source is fixed on by screw on the horizonal base plate of radiator, is coated with thermal grease between the horizonal base plate of the radiating block of led light source and radiator.
Be provided with at least one installing ring, this installing ring has the U-shaped teeth groove,, this installing ring is fixed in the radiator water flat underside back side by screw, and the U-shaped teeth groove cover of installing ring sticks the street lamp arm of light pole.
The utility model street lamp uses the integrated encapsulation of great power LED as light source, because great power LED integrated light-emitting angle is littler than conventional light source, mirror reflects need not be added and the appointed area can be directly projected, light source utilization rate height, colour temperature can be selected between 3000-7000K flexibly, can make glow color more near natural daylight; Need not start-up time.Improved conventional road lamp and utilized sodium vapor lamp, incandescent lamp low, the problem that colour temperature and developing index are low, start-up time is long as light source light-emitting efficiency; The integrated encapsulation of great power LED belongs to cold light source, has characteristics radiationless, noiseless, that the low voltage drive life-span is long.The integrated encapsulation of great power LED simultaneously utilizes a plurality of great power LEDs to be matrix than tradition and arranges and more save cost as light emitting source, and obtains needed projected spot easilier.Because radiator is the cuboid framework, the horizonal base plate of this flute profile radiator is provided with some louvres and fin, and the area of dissipation that passes through accurate Calculation of this radiator can satisfy the heat radiation requirement of corresponding power LED light source, different capacity area of dissipation difference adapts to the market diversification needs.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the parts assembly relation structural representation of integral LED illuminator of the present utility model.
Fig. 2 is led light source heat radiation of the present utility model and the structural representation that the location parts are installed.
The specific embodiment
As shown in Figure 1, led light source 10, lens 11, lower gasket 12, lampshade 13, upper gasket 14, fixed frame 15 orders are fixed on the horizonal base plate 21 front central positions (reference numerals 21 indication positions among Fig. 2) of radiator 20, and their formations can be prevented dust, the totally-enclosed integral LED light source of waterproof.Described lens 11 are installed in led light source 10 tops, and the anaclasis of sending when LED is worked the hot spot of national street lamp prescribed by standard.Led light source adopts the great power LED integrated encapsulation structure, led light source comprises insulator, led chip 101, conducting bracket, lead, radiating block 102, it is annular matrix 103 that described insulative body portion divides the positive and negative conducting bracket of parcel one-body molded, this matrix 103 is installed on radiating block 102 fronts, some led chips 101 are positioned at matrix 103 looping pits and are installed on radiating block 102 fronts, and the positive and negative electrode of some led chips is connected with positive and negative conducting bracket by lead.The radiating block 102 of this led light source is fixed on by screw on the horizonal base plate 21 of radiator 20, is coated with thermal grease (drawing among the figure) between the horizonal base plate 21 of the radiating block 102 of led light source 10 and radiator 20.
