Description

The LED light emitting source

One, affiliated technical field:

The utility model belongs to the LED light emitting source that street lamp uses.

Two, background technology:

What transitional street lamps was used is that sodium vapor lamp is made light emitting source, and the alternating current that it uses 220v not only takes electricity, and service life is short, dangerous.And its light that sends of LED light emitting source is point type, its non-uniform light, the light area coverage is little, brightness is low, making light emitting source brightness and light coverage rate when same with sodium vapor lamp, the number of its used LED is multiplied, cost strengthens greatly, but because LED belongs to cold light, its life-span is long, can use solar energy to make light source, can save thermoelectricity, so people are in the area coverage and the brightness of trying every possible means and improving the LED light emitting source, change its luminous uniformity, but still do not reach street lamp its various performance demands.

Three, summary of the invention:

The utility model is exactly to solve now with the problems referred to above that exist in the technology, provides that a kind of illumination area coverage is big, brightness is high, luminous uniform LED light emitting source.

For addressing the above problem, technical solution of the present utility model is: a kind of LED light emitting source, it is by a plurality of equally distributed LED, LED supports wiring board and the deposited copper cash composition of wiring board, LED comprises tack LED and round end LED, its arrangement mode is: global pattern is a rectangle, three row or two on its left side and the right side are classified round end LED as, its outside vertical tilt angle is 25 °-35 °, from left side fourth line or the third line, per three behaviors Unit one, up to being aligned to right side fourth line or the third line, the outside vertical tilt angle of the LED of its arrangement is 0 °, several first row are arranged as: three tack LED from the left side in each unit, a round end LED, three tack LED, a round end LED, end up to row, secondary series is arranged as: two tack LED begin, a round end LED, three tack LED, a round end LED, three tack LED, up to the end of row, the 3rd row are arranged as: a round end LED, three tack LED, a round end LED, three tack LED, end up to row; Perhaps several first row are arranged as from the left side in each unit: round end LED, three tack LED, round end LED, three tack LED, up to the end of row; Secondary series is arranged as: two tack LED begin, round end LED, three tack LED, round end LED, three tack LED, up to the end of row, the 3rd row are arranged as: three tack LED, round end LED, three tack LED, round end LED, up to the end of row.

The above-mentioned described LED colour temperature of the utility model is 3200K-4000K, and the light color that sends with sodium lamp is close.

Because tack LED full angle is luminous, there is not the dead angle, irradiated area is big, and brightness is not enough, round end LED is that point type is luminous, and irradiated area is little, and the brightness height, the utility model adopts tack and round end LED mixing clocklike, three row on the left side and the right side or two row round end LED the vertical tilt angle is outwards arranged, make its brightness height, can reach more than 20 luxs, irradiated area is big, do not have the dead angle, brightness is even, and the utility model can be according to the width of road, select to form the number of the LED of light emitting source, be fit to the road of various width.
