Description

The LED street lamp

Technical field

The invention belongs to the electric light source technology field, relating to a kind of is the LED street lamp of light source with large-power light-emitting diodes (LED).

Background technology

Adopt the common street lamp of conventional light source, the distribution of its light generally is to adopt the optical lens transmission or adopt the reflector reflection way to carry out, not only power consumption is more for it, and the brightness in its range of exposures is also inhomogeneous, thereby can't produce continuously illuminating effect uniformly in whole highway section when being used for place such as railway, bridge, highway, particularly be difficult to illumination is concentrated in the zone of strip, cause the unnecessary waste of light source.If adopting LED is that light source throws light on, not only be easier to control the switch of irradiation area, and can conservation of power consumption, but common LED illuminating lamp adopts the light emitting diode of plane lattice form distribution as light source more, in actual use, brightness uniformity in its effective illumination range is still relatively poor, has influenced result of use.

Summary of the invention

Technical problem to be solved by this invention is that a kind of good LED street lamp of light area, illuminance distribution, dependability that can form bar shaped is provided.

LED street lamp of the present invention includes a flat base seat, is distributed with a plurality of large-power light-emitting diodes in a rectangular area in pedestal front, and large-power light-emitting diodes multiple row multirow in the rectangular area is arranged in length and breadth; Axis of pitch with the large-power light-emitting diodes distributed areas is the boundary, the axis of pitch front side has the installed surface of several rows large-power light-emitting diodes to turn forward, the axis of pitch rear side has the installed surface of several rows large-power light-emitting diodes to recede, promptly, the installed surface of these inclinations in the vertical and an angle is arranged between the baseplane of pedestal, the big I of this angle is selected between 10 °~30 °.

In the installed surface of above-mentioned forward and backward inclination, near a part of installed surface of axis of pitch and pedestal baseplane angle in the vertical less than than a part of installed surface and pedestal baseplane angle in the vertical away from axis of pitch.

In addition, the horizontal outermost in above-mentioned large-power light-emitting diodes distributed areas can also have the installed surface of some row large-power light-emitting diodes to tilt towards the longitudinal axis direction in the horizontal.

In above-mentioned large-power light-emitting diodes distributed areas, the lighting angle parameter of large-power light-emitting diodes reduces to the periphery gradually from the middle part.

In order to improve the radiating effect of large-power light-emitting diodes, improve the reliability of its work, also be provided with the multi-disc metal fin vertical with the pedestal baseplane at the back side of pedestal.

The front of above-mentioned pedestal can be enclosed in the case, is provided with transparency window in the front of case.

LED street lamp of the present invention not only can form the field of illumination of strip, and because the installed surface of large-power light-emitting diodes is obliquely installed, make peripheral large-power light-emitting diodes to slope inwardly, cooperate the distribution of the large-power light-emitting diodes of different lighting angles, can make full use of radiation source, the brightness of outer peripheral areas is replenished, improved the brightness uniformity in effective irradiation area; In addition, LED street lamp of the present invention is provided with metal fin, has strengthened its radiating effect, has improved dependability.

The specific embodiment

As shown in Figure 1, be distributed with a plurality of large-power light-emitting diodes 2 in the rectangular area in pedestal 1 front of LED street lamp of the present invention, large-power light-emitting diodes multiple row multirow in the rectangular area is arranged in length and breadth;

As shown in Figure 3, Figure 4, axis of pitch (being the X-axis among Fig. 1) with the large-power light-emitting diodes distributed areas is the boundary, the axis of pitch front side has the installed surface 11 of several rows large-power light-emitting diodes to recede, the axis of pitch rear side has the installed surface 11 of several rows large-power light-emitting diodes to turn forward, promptly, the installed surface 11 of these inclinations in the vertical and an angle (α angle among Fig. 3 and β angle) is arranged between the baseplane 12 of pedestal, the big I of this angle is selected between 10 °~30 °.

As shown in Figure 3, in the installed surface 11 of above-mentioned forward and backward inclination, the a part of installed surface 11 near axis of pitch is α with pedestal baseplane 12 angle in the vertical, and a part of installed surface 11 away from axis of pitch is β with pedestal baseplane 12 angle in the vertical, and folder α is greater than angle β.

As shown in Figure 2, the horizontal outermost of large-power light-emitting diodes distributed areas also has the installed surface 11 of some row large-power light-emitting diodes to tilt towards longitudinal axis (being the Y-axis among Fig. 1) direction in the horizontal.

As shown in Figure 4, the back side of pedestal is provided with metal fin 3, and the front of pedestal 1 is enclosed in one and has in transparency window 41 cases 4.
