Abstract

The utility model belongs to the technical field of lighting devices and discloses an LED streetlamp which comprises a shell, a glass hood, a connection assembly and a lighting assembly. The lighting assembly is located in a cavity formed by the shell and the glass hood. A radiating assembly is arranged on the upper surface of the shell. The principle that hot air flows upwards is fully utilized, an air flue is designed and the radiating effect is boosted by returning air.

Description

The LED street lamp
Technical field
The utility model belongs to technical field of lighting fixtures, relates to especially that a kind of good heat dissipation effect, light loss are little, the LED street lamp of long service life.
Background technology
Street lamp is showed the light fixture that road provides illumination functions, the light fixture in the general reference traffic lighting in the road lighting scope.The infield is common in road one-sided or both sides.Be often referred to and be contained on post, along the street in discrete a series of lamps (as arc lamp) on road or highway.Be arranged on road other for illuminating lamp.Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and high-pressure mercury lamp 360 degree are luminous, and the shortcoming that light loss is large has caused the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at the development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, the coming into existence situation of critical shortage of supply of electric power, and energy-conservation is institute's urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the LED street lamp of environmental protection is of great significance the energy-conservation tool of city illumination.Along with the urgency of country to attention and the reducing energy consumption of energy-saving and emission-reduction work, also will widely popularize the LED street lamp, it is the high efficiency solid-state light source that the faint electric energy of use that a kind of based semiconductor PN junction forms just can be luminous, under certain forward bias voltage and Injection Current, the electronics that injects the hole in P district and injection N district sends photon diffusing to active area by radiation recombination, electric energy is converted into luminous energy.It is a kind of solid-state cold light source, the characteristics such as have environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long, and therefore, the LED street lamp will become the optimal selection of roadway illumination and energy saving transformation.When using the LED street lamp, need to solve the road lamp cooling problem, existing LED street lamp back cover plate employing outer surface is planar shaped or curved surface shaped, and radiating effect is not good.
Summary of the invention
Technical problem to be solved in the utility model is: provide that a kind of good heat dissipation effect, light loss are little, the LED street lamp of long service life.
Technical solution adopted in the utility model is: a kind of LED street lamp, comprise housing, cloche, coupling assembling and light fixture, and described light fixture is positioned at the die cavity of housing and cloche formation, and described housing upper surface is provided with radiating subassembly.
Described radiating subassembly comprises the spaced multi-disc fin that is arranged on the housing upper surface.
Described coupling assembling comprises installation sleeve and lock screw, and installation sleeve one end is connected with housing, and lock screw is arranged on above installation sleeve.
Described light fixture comprises light source shelf, light source cover and light source.
Described light source is the LED lamp.
Described LED lamp connects a photosensitive switch.
The beneficial effects of the utility model are: the utility model LED street lamp, at the upper surface of housing, radiating subassembly is set, and take full advantage of the principle that hot-air makes progress, adopt the air duct type design, air return increases radiating effect.
As preferably, described radiating subassembly comprises the spaced multi-disc fin that is arranged on the housing upper surface, improves radiating efficiency.
As preferably, described coupling assembling comprises installation sleeve and lock screw, and installation sleeve one end is connected with housing, and lock screw is arranged on the installation sleeve top, and is easy for installation.
As preferably, described light fixture comprises light source shelf, light source cover and light source, and described light source is electrically connected to an arrester, reduces thunderbolt to the infringement of street lamp.
As preferably, described light source is the LED lamp, and brightness is high, light loss is little, low, the long service life of power consumption.
Described LED lamp connects a photosensitive switch.The use of photosensitive switch is being unfavorable for that the place that control circuit is installed regulates the open and close of this lamp voluntarily by the power of extraneous light especially.

The specific embodiment
Be below the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.
With reference to shown in Figure 1, a kind of LED street lamp of the utility model comprises housing 1, cloche 2, coupling assembling and light fixture, and described light fixture is positioned at the die cavity of housing 1 and cloche 2 formation, and described housing 1 upper surface is provided with radiating subassembly.Housing 1 inner surface also is provided with reflector.
Described radiating subassembly comprises the spaced multi-disc fin 1.1 that is arranged on housing 1 upper surface, improves radiating efficiency.
Described coupling assembling comprises installation sleeve 3 and lock screw 3.1, and installation sleeve 3 one ends are connected with housing 1, and lock screw 3.1 is arranged on installation sleeve 3 tops.
Described light fixture comprises light source shelf, light source cover and light source.Light source cover adopts the freeform optics design of specialty, take full advantage of the characteristics of LED directional lighting, fully guaranteeing under the prerequisite of light extraction efficiency, improve to greatest extent the geometry utilization of LED, the luminous energy that impinges upon on the road surface reaches more than 80%, thus the light loss of having avoided to greatest extent street lamp to cause.
Described light source is the LED lamp, and brightness is high, light loss is little, low, the long service life of power consumption.
Described LED lamp connects a photosensitive switch 4.The use of photosensitive switch 4 is being unfavorable for that the place that control circuit is installed regulates the open and close of this lamp voluntarily by the power of extraneous light especially.
The utility model LED street lamp arranges radiating subassembly at the upper surface of housing 1, takes full advantage of the principle that hot-air makes progress, and adopts the air duct type design, and air return increases radiating effect.As improvement, each parts such as housing 1 grade adopt light-weight design, alleviate as far as possible the deadweight of product and the weight of whole lamp.
