Abstract

The utility model relates to an LED street lamp with a large illumination angle. The LED street lamp realizes a large illumination angle and extensive illumination. The street lamp comprises a ladder-shaped lamp holder, a reflector, a radiator and a lampshade. The ladder-shaped lamp holder is provided with a luminous body, which is formed by a plurality of arranged LED lamp beads and is disposed on the ladder-shaped side and right bottom of the ladder-shaped lamp holder; top of the ladder-shaped lamp holder is provided with the reflector capable of preventing dust and condensing light; the lampshade is installed on the luminous body; and the upper portion of the ladder-shaped lamp holder is provided with the radiator. The LED street lamp provide by the utility model has a simple structure and a large illumination angle, thereby effectively solving the technical problem that a conventional street lamp has the illumination angle being 90 degrees at a maximum and a small illumination scope, and is easy to install and has a long service lifetime.

Description

A kind of LED street lamp of large illuminating angle degree

One, technical field

The utility model relates to street lamp, relates in particular to the LED street lamp of a kind of large illuminating angle degree of illumination on a large scale.

Two, background technology

In recent years, along with the continuous lifting of the continuous development of LED scientific research and the chip technology level of production, the maturation of high-power LED encapsulation technology, the LED luminous efficiency is greatly improved, and its application is progressively widened.Therefore the LED lamp is applied to street lighting in a large number.But because the irradiating angle of LED lamp itself is narrow.Therefore, it is desired to reach national street lamp standard (in July, 2007 enforcement), and the illumination zone when high 12 meters of lamp is that the rectangular light spot of 12m * 33m requires just to be difficult to realize.

Although the design of some LED street lamp increases irradiating angle and produces rectangular light spot with transmissive mirror, but because the general maximum illumination angle of ordinary lens is 90 degree, so irradiating angle is still little, still be difficult to reach the requirement of the rectangular light spot of regulation, therefore, the irradiating angle of LED street lamp has been subjected to very big constraint, the requirement that is difficult to be up to state standards.

Three, summary of the invention

At above-mentioned technical problem, for overcoming the defective of prior art, the purpose of this utility model just provides a kind of LED street lamp of large illuminating angle degree, and it is big effectively to solve irradiating angle, realizes the problem of illumination on a large scale.

The technical scheme that the utility model solves is, comprise trapezoidal lamp socket, reflection shield, radiator and lampshade, there are a plurality of LED lamp pearls to rearrange illuminator on the trapezoidal lamp socket, and place trapezoidal lamp socket trapezoidal side and just below on, the reflection shield of dustproof optically focused is arranged at trapezoidal lamp socket top, lampshade is housed on the illuminator, and radiator is equipped with on trapezoidal lamp socket top.

The utility model is simple in structure, and irradiating angle is big, and efficiently solve existing street lamp irradiating angle maximum and have only 90 °, the technological deficiency that range of exposures is little, and also easy for installation, long service life.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Shown in Fig. 1-3, the utility model comprises trapezoidal lamp socket, reflection shield, radiator and lampshade, there are a plurality of LED lamp pearls 4 to rearrange illuminator on the trapezoidal lamp socket 2, and place trapezoidal lamp socket trapezoidal side and just below on, the reflection shield 3 of dustproof optically focused is arranged at trapezoidal lamp socket top, lampshade 5 is housed on the illuminator, and radiator 1 is equipped with on trapezoidal lamp socket top.

In order to guarantee result of use, described radiator is to be arranged in parallel to combine by a plurality of radiating blocks to constitute; Described trapezoidal side horizontal sextant angle is 50-70 °; Described trapezoidal lamp socket by a positive bottom surface and and four trapezoidal skew backs (inclined-plane) forms, positive bottom surface and and four trapezoidal sides on lamp pearl 4 is housed, by multi-angle irradiation increase illumination range; Described reflection shield is contained in the centre of trapezoidal lamp socket and radiator; it (is the extended line exterior angle of the lampshade horizontal plane of reflection shield inclined-plane and protection usefulness that its horizontal sextant angle is 120 °; as shown in Figure 2); can increase illumination brightness by the refraction of reflection shield angle; also has the dustproof effect simultaneously; when LED lamp pearl 4 was lighted, a was passed through on the wherein a part of surface that shines reflection shield of the light a that it produced ₁The position arrives a through reflection ₂At this moment the position, is exactly the needed range position of our normal illumination.

Lampshade is used to protect the sealing of LED lamp pearl, to avoid pollution such as dust, guarantees the brightness of illuminator, increases the service life.

In a word, the utility model irradiating angle is big, can realize the evenly problem of illumination on a large scale, and good dustproof effect, the light utilization efficiency height, and long service life is the innovation on the street lamp.
