Abstract

The utility model relates to the field of illumination lamps, especially relates to an LED street lamp which applies LED in lighting. The LED street lamp comprises a lamp panel housing, a plurality of LEDs arranged in the lamp panel housing and an LED drive power supply, wherein the lamp panel housing consists of an arc-shaped upper cover plate and a lower base plate arranged under the cover plate. The utility model is characterized in that the lower base plate is inlaid with a reflection layer in a flat plate shape; the LEDs are arranged on the back surface of the reflection layer in a matrix; the lower base plate is fixed to a radiator in a flat plate shape. Making improvements on current street lamps, the utility model has advantages of effectively resolving the disadvantage of new light source that the using cost is too high, saving investment cost and achieving a smooth transition between the new light source and the old one; possessing good heat dissipation and good water and dust resistance; being especially suitable for practical road lighting.

Description

A kind of LED street lamp

Technical field

The utility model relates to field of illuminating lamps, relates in particular to the LED street lamp that a kind of LED is applied to lighting use.

Background technology

Transitional street lamps adopts high-pressure mercury lamp, mercury lamp or Halogen lamp LED as light source mostly, and energy consumption is big, the life-span is short, low temperature is difficult for shortcomings such as startup.Development along with the LED technology, LED as light source in recent years by a large amount of uses, its compare with traditional lamp source possess energy-saving and environmental protection, advantage that the life-span is long, but at present since the LED cost also than higher, and single LED luminance is lower, and will satisfy the traditional street lamp of large-scale replacement, and spending will be huge, also unrealistic, cause the popularization difficulty of new light sources on the contrary.Therefore the fusion that solves conventional road lamp form and new light sources just becomes the object of the utility model research.

The utility model content

The utility model just is being aimed at this, utilizes the transitional street lamps structure, improves the route of its light source and light and the LED street lamp of a kind of new structure of designing.

The utility model adopts following technical scheme:

LED street lamp of the present utility model comprises a lamp panel shell, is arranged at a plurality of LED and a LED driving power in the lamp panel shell, and described lamp panel shell is made up of an arc upper cover plate and the lower shoe under it.Wherein, inlay a flat reflector layer on the lower shoe, described LED arranged in matrix is in the back side of described reflector layer, and described lower shoe is also fixed a tabular radiator.

Further, described lower shoe and be positioned at the LED top position and be provided with a transparent lamp shade.

Further, described lower shoe is provided with buckle for the edge with transparent lamp shade, by buckle described transparent lamp shade is fixed on the lower shoe.

Further, be provided with sealing ring between described lower shoe and the transparent lamp shade.

Further, be provided with the thermal conductive silicon glue-line between described LED and the reflector layer.

Further, described lamp panel shell is provided with one through hole is installed, and is used for fixing to be installed on the street lamp body of rod.

Further, described LED driving power is arranged in the described lamp panel shell.

Further, described reflector layer is the metal luminescent layer, and is shaped as rectangle.

The utility model adopts as above technical scheme, and present street lamp is improved, and effectively solves the too high shortcoming of new light sources use cost, and the cost of reducing investment outlay reaches seamlessly transitting of new light sources and old light source.The utility model has realized that a kind of radiating effect is excellent, the LED street lamp of water proof and dust proof, is specially adapted to actual road illumination.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a right view of the present utility model.

The specific embodiment

Now with the specific embodiment the utility model is further specified in conjunction with the accompanying drawings.

Consult Fig. 1, Fig. 2 and shown in Figure 3, LED street lamp of the present utility model comprises a lamp panel shell, is arranged at a plurality of LED and a LED driving power in the lamp panel shell, and described lamp panel shell is made up of an arc upper cover plate 1 and the lower shoe 2 under it.Wherein, inlay a flat reflector layer 4 on the lower shoe 2, described LED9 arranged in matrix is in the back side of described reflector layer 4, and described lower shoe 2 is also fixed a tabular radiator 8.Preferably, be provided with the thermal conductive silicon glue-line between described LED9 and the reflector layer 4.By the setting of tabular radiator 8 and thermal conductive silicon glue-line, the heat of LED can be delivered on the lamp panel shell, and by tabular radiator 8 heat be dispersed in the outside air quickly and go.Preferably, described reflector layer 4 is metal luminescent layers, and is shaped as rectangle.The light that the luminescent layer of metal also not only can better emit LED9 collects in one, can strengthen the brightness of light, increases the irradiation distance of light, and possesses the effect of heat conduction simultaneously.

Described lower shoe 2 and be positioned at the LED9 top position and be provided with a transparent lamp shade 7.Preferably, described lower shoe 2 is provided with buckle for the edge with transparent lamp shade 7, by buckle described transparent lamp shade 7 is fixed on the lower shoe 2.Like this, can maintain easily.Preferably, be provided with sealing ring between described lower shoe 2 and the transparent lamp shade 7.By the setting of sealing ring, enter in the lamp body to avoid rainwater or steam, destroy the accessory in the lamp body.Therefore, LED street lamp of the present utility model can play the dustproof effect of excellent waterproof, is specially adapted to the rural road illumination.

Described lamp panel shell is provided with one through hole 3 is installed, and is used for fixing to be installed on the street lamp body of rod.Described LED driving power 6 is arranged in the described lamp panel shell.

The utility model uses a kind of led light source, present street lamp is improved, to reach energy-conservation and purpose that reduce investment outlay.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
