Abstract

A lamp cap structure of an LED street lamp comprises a housing; a shade connected to the housing; and a PCB, on which an LED street lamp working circuit and LED lamps are integrated. The lamp cap structure is characterized in that the lamp cap also includes a lens fixedly connected with the front side of each LED lamp, wherein each lens has two connection sections on both sides; a through hole for allowing a screw to pass through is formed on the connection sections; and a screw hole aligned to the through hole on the corresponding lens and allowing the screw to pass through is respectively formed on both sides of each LED lamp on the PCB. Compared with the prior art, the lamp cap structure has convenient installation and reliable connection by connecting the lens with the front side of each LED lamp and fixing the lens on the PCB via screws through the connection sections on both sides. Accordingly, the LED lamp is protected by the lens to prevent damage during transportation.

Description

The holder structure of LED street lamp

Technical field

The utility model relates to a kind of lamp cap device of street lamp, particularly relates to the lens mounting structure of this LED road lamp cap.

Background technology

Light emitting diode (LED) because have that the intensity of giving out light height, energy consumption are low, advantages such as long service life and non-secondary pollution, therefore be widely used in every field, at present, street lamp also begins more and more to use light emitting diode as light source, to reach the purpose of energy-conserving and environment-protective.But, what LED sent is a branch of light rather than diverging light, make LED directly limited as the illumination zone of light source, in order to guarantee the illuminating effect on road surface, street lamp is provided with convex lens usually and is used for spreading the light beam that the LED lamp sends in lamp holder, whether the installation of lens rationally reliably then directly has influence on the illuminating effect and the dependability of street lamp.

In the prior art, common lens fixed form is that lens directly are set on each LED lamp, as the patent No. is that Chinese utility model " a kind of LED road lamp light distribution lens " patent No. of ZL200820050703.5 is Chinese invention patent " LED street lamp and lens thereof " of ZL200710073278.1 etc., the lens mounting means of above-mentioned patent is easy to operate, card is established continuous between lens and the LED lamp, be convenient to change, but it is loosening easily between lens and the LED lamp that the shortcoming of this connected mode is in transportation and the use, will have a strong impact on the bright dipping and the light distribution effect of street lamp.

In addition, in order to prevent that lens and LED lamp break away from, also there is employing that lens all are arranged on the installing plate, if any application number is the street lamp that 200810208224.6 Chinese invention patent " a kind of lampshade and LED street lamp with light-distribution lens " discloses a kind of like this structure, its lampshade is made of cover body and light-distribution lens, covers body is a strip, is evenly distributed with some light-distribution lens on it.In this patent, all lens all are fixed on the cover body and this cover body becomes one, though it is easy for installation, quick, cover body directly can be fastened on the circuit board that is welded with the LED lamp, still, will increase the LED lamp like this and be welded to difficulty on the circuit board, the position of the LED lamp after must guaranteeing to weld and the lens on the cover body align one by one, otherwise when mounted, can influence the service life of LED because LED lamp and lens depart from and damage the LED lamp easily.

Summary of the invention

Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of install with transportation in the not fragile and lens of LED lamp be connected reliable LED street lamp holder structure with the LED lamp.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the holder structure of this LED street lamp includes

Shell, its surface offers a cavity;

Lampshade is connected on the described shell and with described cavity and forms a chamber that seals;

The PCB circuit board is integrated with LED street lamp operating circuit, and this PCB circuit board is contained in the described chamber; And

The LED lamp is arranged on the described PCB circuit board and with described operating circuit formation and can supplies the luminous current loop of this LED lamp;

It is characterized in that: also include the lens that are fixedly connected on each LED lamp front portion, wherein, the both sides of each described lens have a junction respectively, offer a through hole that can pass for screw on the described connecting portion, described pcb board the both sides of each LED lamp offer respectively one with corresponding lens on the described through hole screw that aligns and can supply described screw to pass.

In order to strengthen reflection action, improve the whole light emission rate of LED lamp, also be equipped with a metallic plate that is connected described pcb board top in the described chamber, offer on this metallic plate a plurality of can be respectively and described LED lamp spacing hole one to one, the lens of described LED lamp front portion are fastened on respectively in the corresponding spacing hole.So, by the reflex of metallic plate, can further strengthen the radiative intensity of LED lamp, improve the luminous utilization rate of LED lamp; And, owing to also offer spacing hole on the metallic plate, spacing hole has and to be connected the lens of corresponding LED lamp front portion suitable and can hold the opening size that these lens pass, so, the lens of each LED lamp front portion can just be fastened in the corresponding spacing hole on the pcb board, improve the reliability that lens are connected with the LED lamp; In addition, metallic plate is arranged on the top of pcb board, and the spacing hole on the metallic plate only passes for lens, the connecting portion of lens both sides can be covered up, and makes outward appearance more neat and artistic.

Compared with prior art; advantage of the present utility model is: be connected with lens in the front portion of each LED lamp; and; lens are that the connecting portion by both sides is fixedly connected on the PCB circuit board by screw; easy for installation, connect more reliable; and; this connected mode makes the LED lamp that the lens protection be arranged in transportation; not fragile; each lens all is to be arranged separately in corresponding LED lamp front portion; lens are difficult for loosening in installation and use, and then have prolonged the service life of road lamp cap.
