Abstract

The invention relates to the field of communal facilities, in particular to a street lamp, and discloses a lateral LED street lamp. The lateral LED street lamp is composed of a lamp pole and a lamp cap assembly. The lamp cap assembly is arranged at the top of the lamp pole and comprises a reflection plate, a pair of light guide plates, a pair of LED light source sets, a pair of diffusion plates, a lamp shell and a pair of transparent curved lampshades, the lamp shell is a box with openings in the two ends, the transparent curved lampshades are fixedly arranged at the openings in the two ends of the lamp shell, the reflection plate is arranged on the central line in the lamp shell, the light guide plates are arranged on the two sides of the reflection plate in a central symmetry mode, the diffusion plates are arranged on the light emitting faces of the light guide plates, and the LED light source sets are arranged on the light entering faces of the light guide plates. The cost of the street lamp is lowered, the structure is simplified, and meanwhile losses caused by light reflection are basically avoided. Light-transmitting losses caused by dust are reduced, the light source utilization rate can be kept about 85 percent in the long-time work, and important significance in energy saving and environmental protection is achieved.

Description

Side direction LED street lamp

Technical field

The present invention relates to communal facility field, relate in particular to a kind of street lamp.

Background technology

A modern city, in order to ensure the needs of city lighting, all can install row's street lamp as lighting apparatus on the both sides of each road; Existing street lamp as shown in Figure 1, is vertically fixed on the lamp stand on ground with one conventionally, and fixes a lamp holder formation at lamp stand top; Lamp stand welding manner is automatic submerged-arc welding, welding is reliable, and smooth surface, without weld defects such as obvious pore, overlap, undercuts, ultrasonic examination inspection, steel pole preservative treatment adopts inside and outside galvanizing, and zincincation process is through the processes such as overpickling, galvanizing, washing, phosphatization, passivation, Several Thiourea Derivatives on Zinc Plate Surface smooth and beautiful appearance, gloss is consistent, exist without defects such as elephant skin, stream pendant and list edge, peeling, spot, male and female faces, more than zinc coating thickness reaches 86um, the anticorrosion life-span is greater than 30 years; Lamp holder comprises that bulb, lampshade and three parts of transparency cover form, and wherein bulb adopts electricity-saving lamp or incandescent lamp bulb, and lampshade inner surface is the reflecting surface of aluminum polishing, and transparency cover is curved surface high-strength armoured-glass.

The problem of existing this class street lamp mainly contains 2 points, one, bulb is subject to the impact of lampshade and transparency cover shape, conventionally be merely able to a pocket of illumination lamp below, therefore in order to make whole street can ensure that certain brightness can only improve the layout density of street lamp, has so just improved construction cost, and has increased power consumption, two, although the initial reflecting rate of the reflecting surface of aluminum polishing is higher, but after use passivation after a while, conventionally can only remain on 85% left and right, and the initial light transmittance of street lamp transparency cover also only has 90% left and right, street lamp quantity is a lot, highly also very high, cannot pass through sanitationman's cleaned at regular intervals, and transparency cover is towards ground, also cannot utilize rainwater naturally clean, therefore after date while using a section is because the impact of the factors such as dust, light transmittance is less than 70% often, whole like this street lamp only has 65% to the actual light utilization sending of bulb, waste a large amount of electric energy, the quantity of city street lamp is very large, therefore total electric energy of waste is very considerable.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of side direction LED street lamp, in the lamp holder of this street lamp, be provided with two LED illuminating module, two LED illuminating module Central Symmetries arrange the reflecting plate that shares a PET material, reduce the cost of street lamp, and in simplified structure, substantially avoid light to reflect the loss causing, after having used LED illuminating module as light source, the power consumption of a needs 20% can meet existing road surface and illuminate demand.

The present invention is achieved in that a kind of side direction LED street lamp, formed by lamp stand and lamp adapter assembly two parts, described lamp adapter assembly is arranged on the top of lamp stand, described lamp adapter assembly comprises a reflecting plate, a pair of LGP, pair of LEDs light source group, a pair of diffuser plate, one lamp housing and a pair of transparent curved surface lampshade, described lamp housing is the box body of a both ends open, a pair of described transparent curved surface lampshade is fixedly mounted on the opening part at lamp housing two ends, described reflecting plate is arranged on the midline in lamp housing, a pair of LGP Central Symmetry is arranged on the both sides of reflecting plate, described diffuser plate is arranged on the exiting surface of LGP, described LED light source group is arranged on the incidence surface of LGP.

Described lamp stand is one to be vertically fixedly mounted on ground stock.

Described stock is round steel pipe.

Described LGP is right-angled trapezium, and described LED light source group is arranged on one side longer in right-angled trapezium top margin and base.

The material of described reflecting plate is PET.

Described diffusion edges of boards portion is provided with locating dowel, and diffuser plate is fixedly mounted in lamp housing by locating dowel.

In the lamp holder of side direction LED street lamp of the present invention, be provided with two LED illuminating module, two LED illuminating module Central Symmetries arrange the reflecting plate that shares a PET material, reduce the cost of street lamp, and in simplified structure, have substantially avoided light to reflect the loss causing; The exiting surface of street lamp is arranged on the side direction of lamp housing, can make street lamp to illuminate scope larger, reduced street lamp density requirement; The transparent curved surface lampshade that is positioned at equally side can be subject to directly washing away of rainwater, reduce because the transmission losses that dust causes, in long-term work, can make light source utilization rate remain on 85% left and right, after having used LED illuminating module as light source, only need 20% power consumption can meet existing road surface and illuminate demand, energy-conserving and environment-protective are had great significance, there is application value widely.
