Abstract

The utility model relates to a street illumination lamp, in particular to a module street lamp comprising an LED module and a heat dissipating plate. The LED module is attached to the heat dissipation plate. The module street lamp further comprises a lamp cap module, a rear end cover, side supports and a ventilation plate, wherein the ventilation plate is fixed on the lamp cap module, the heat dissipation plate is fixedly connected with the ventilation plate, one side of the heat dissipation plate is attached to the lamp cap module, the other side of the heat dissipation plate is attached to the rear end cover, and the side supports are arranged on two sides of the ventilation plate and connected with the ventilation plate and the heat dissipation plate. According to the structure, the back of the heat dissipation plate is provided with the ventilation plate. Due to the fact that hot air flow is generated when the heat dissipation plate dissipates heat, if directly exposed, the heat dissipation plate is directly connected with external air and is influenced by external temperature. Therefore, the ventilation plate is additionally arranged for isolation protection and fast heat dissipation. The module street lamp is compact in structure, a lamp cap can be connected with a lamp base of the street lamp after assembly, and installation of the street lamp is finished, and the installation is very convenient.

Description

Modular street lamp

Technical field

The utility model relates to a kind of road illuminating lamp, especially a kind of modular street lamp.

Background technology

LED street lamp (Light Emitting Diode, Light-Emitting Diode) is semi-conductor lighting lamp.It is the efficient solid state light emitter that the faint electric energy of usefulness that a kind of based semiconductor PN junction forms just can be luminous, under certain forward bias voltage and injection electric 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, has characteristics such as environment friendly and pollution-free, little power consumption, light efficiency height, life-span be long, and therefore, the LED street lamp will become the optimal selection that roadway illumination and energy saving is transformed.

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 big 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, energy-conservation is present institute urgent problem, and road lighting and people's productive life are closely related, quickening along with Urbanization in China, the LED street lamp is luminous with orientation, power consumption is low, drive characteristic is good, response speed is fast, the shock resistance height, long service life, advantages such as environmental protection enter into people's the visual field gradually, become the energy-conserving light source of new generation that has alternative conventional light source advantage in the world most at present, therefore, the LED street lamp will become the optimal selection that roadway illumination and energy saving is transformed.

Defectives such as but LED street lamp ubiquity is installed inconvenience at present, and radiating effect is bad have influenced popularizing and service life of LED.

Summary of the invention

The purpose of this utility model is, a kind of modular street lamp of easy for installation, good heat dissipation effect is provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of modular street lamp, comprise LED module, heat sink, the LED module is sticked on heat sink, also comprise lamp holder module, rear end cap, limit support, ventilating board, ventilating board is fixed on the lamp holder module, and heat sink is fixedlyed connected with ventilating board, heat sink one side and lamp holder module are fitted, opposite side and rear end cap are sticked, and the limit support is arranged on the both sides of ventilating board, connect ventilating board and heat sink.

Of the present utility modelly further be set to: also comprise power supply, power supply lid, be provided with a power source cavity in the lamp holder module, power supply is fixedly installed in the power source cavity, and the power supply lid is fixedly installed on the power source cavity.

Of the present utility modelly further be set to: also comprise intermediate support, at bottom protrusion one contiguous block of lamp holder module, an end of intermediate support is fixedlyed connected with contiguous block, and ventilating board is fixedly installed on the intermediate support.

Said structure arranges a ventilating board at the back of heat sink, because heat sink when dispersing heat, can produce thermal current; if directly exposed, can directly directly be connected with the air in the external world, can be subjected to externally temperature influence equally; therefore add ventilating board; the one, for insulation blocking, the 2nd, for quick heat radiating, the utility model compact conformation; after assembling; can directly lamp holder be connected with the lamp socket of street lamp, just finish installation, install very convenient.
