Description

A kind of outdoor LED light fixture

Technical field

The utility model relates to a kind of LED lighting engineering, especially relates to a kind of LED light fixture of open air.

Background technology

In led light source was used, particularly in high-power, high brightness outdoor LED light source applications, the light efficiency of led light source, light decay, life-span and LED junction temperature were contacted directly.Therefore, how to reduce the LED junction temperature and just become the key that guarantees the led light source reliably working and keep useful life.Simultaneously, the semiconductor devices that comprises LED all has the requirement of storage temperature, roughly at-40 ℃～135 ℃.

But, in the practical application, requirement for installation, assembling and aspect such as attractive in appearance, it is too big that light fixture often can not be done, therefore led light source and driving power circuit thereof often are arranged in the limited scope in space, each spontaneous heating of led light source and driving power circuit influences each other again, causes the operating ambient temperature of LED and driving power circuit all can improve; And if the LED lamp body is exposed to the sun under daylight, LED also can place an environment that temperature is very high for a long time under off working state, thereby poor effect.

At present, the outdoor LED light fixture is many by adopting conventional streetlamp housing to convert or designing with reference to conventional road lamp body both at home and abroad.Its shortcoming is because the restriction of road lamp body volume shape, having limited the heat of dress lamp power or led light source generation can not be derived by lamp body fast, can not effectively solve be exposed to the sun adverse effect under sunlight of electronic device, limited high-power and high-luminance LED light source out of doors with city illuminations such as street lamp and view on application and popularization.

Summary of the invention

The purpose of this utility model is to overcome shortcoming of the prior art, a kind of outdoor LED light fixture of tool high heat dispersion is provided, cause short problem of big life-span of LED light decay to reduce in high-power outdoor LED light fixture and the street lamp because heat dissipation problem can not effectively solve, thereby prolong the service life of led light source and improve result of use.

The purpose of this utility model is achieved in that a kind of outdoor LED light fixture, it comprises support, heat radiation lamp body and electric appliance box are installed on support, in the heat radiation lamp body led light source is arranged, the LED driving power is arranged in the electric appliance box, it is characterized in that: a sunshading board is installed on support, this sunshading board be positioned at the heat radiation lamp body and above the electric appliance box and reserve the heat radiation gap, the outer surface of heat radiation lamp body has radiating ribs, and wherein the radiating ribs of peripheral side is laminated structure and arranges radially.

In order to make the wind from different directions improve radiating effect swimmingly by the radiating ribs at heat radiation lamp body top, described heat radiation lamp body top constitutes the radiating ribs that multi-angle all has the air draught passage by some changeable shape fin.

Described heat radiation lamp body has air-vent and is covered with waterproof ventilated membrane at sidewall and top.

An acute angle angle is formed on described sunshading board and lamp body top, and this angle can improve ventilation, thereby improves radiating efficiency.

Described sunshading board is a solar panel, also being provided with charging-discharging controller in the described electric appliance box is connected with external battery, solar panel is connected by the charging-discharging controller in lead and the electric appliance box, external battery and LED driving power, and the output of LED driving power is connected with led light source.

Temperature sense probe is housed in the described heat radiation lamp body, and described LED driving power is the controllable LED driving power, and the temperature sense probe is connected with controllable LED driving power in the electric appliance box by lead.

The utility model compared with prior art has following advantage: 1, have very high heat dispersion, to reduce in the high-power outdoor LED light fixture because the short influence of big life-span of the bad LED of the causing light decay of heat radiation.Thereby prolong the service life of led light source and improve result of use; 2, by the application of sunshading board, allow heat radiation lamp body and electric appliance box avoid directly being exposed to the sun in the sun, the temperature that has reduced heat radiation lamp body and electric appliance box is in the good operation state of temperature to guarantee led light source and electrical equipment; 3, sunshading board is replaceable is solar panel, and installing scalable is solar energy outdoor LED light fixture; 4, the radiating ribs of heat radiation lamp body peripheral side is laminated structure and arranges radially, the top constitutes the radiating ribs that multi-angle all has passage by some changeable shape fin, it can make the wind from different directions improve radiating efficiency swimmingly by the radiating ribs of heat radiation lamp body; 5, open air-vent and apply waterproof ventilated membrane respectively at thermal louver body sidewall and top, under the device duty, can be operated under the desirable temperature to guarantee led light source, guarantee the water proof and dust proof grade of heat radiation lamp body simultaneously at the inner cross-ventilation that forms of lamp body; 6, unit temp inductive probe in the heat radiation lamp body, LED operating temperature in the heat radiation lamp body is fed back to controllable LED driving power in the electric appliance box, the controllable LED driving power can be adjusted the LED drive current automatically according to temperature signal, is operated under the suitable power and state of temperature to guarantee led light source.
