Cross and place solid-state sealing silica gel ring and the connection of filling liquid silica gel, circuit board of the assembling with LED lamp bead radiator, be arranged on
Closing, the inner side gradient for making a circle in main body front week are 50 ° ~ 60 ° of annular shirt rim, are being arranged on the main body just
Face, all lens units are surrounded wherein, and the height of projection of the annular shirt rim includes that lens unit exists more than Combined lens
The height of projection of interior all protrusions, between adjacent buckle set bottom flushed with the bottom of radiator principal plane, height greatly
In or equal to the radiator principal plane overhead height and the principal plane of the radiator is enclosed in interior circle muscle, should
Gap is formed between circle muscle and radiator, lens unit is symmetrical expression luminous intensity distribution along track direction, and vertical track direction is done polarisation and set
Meter.
Preferably, being snapped connection by positioned at the positive multiple of main body between the Combined lens and radiator.
Preferably, the junction between the circle muscle and buckle is respectively provided with a U-shaped breach.
Preferably, the back side of the main body is provided with bonding wire resigning groove, waterproof groove and screw resigning groove.
Preferably, a kind of refractive index of filling is 1.55 in the back side groove of the lens unit, it is with silica gel refractive index
1.53rd, PC refractive indexes are 1.58 transparent colloid.
As a result of the LED light source module that said structure, the utility model are provided so that most of light is all distributed in road
On face, luminous intensity distribution is carried out to LED street lamp, it is rectangle that the light for exporting LED street lamp is radiated at the light type formed on road surface, is met
The brightness on road surface, illumination, the requirement of the uniformity, have taken into full account the relative bearing between light fixture, point of observation, people, the material on road surface
Situations such as illumination between matter and street lamp is superimposed, increases uniformity of illuminance and luminance uniformity, reduces dazzle value, pacifies meeting
Accomplish energy-conservation as far as possible under the premise of complete comfortable.
