Description

A kind of new waterproof type plug-in type electrical connector and street lamp

Technical field

The utility model relates to LED technology field, in particular to a kind of new waterproof type plug-in type electrical connector and street lamp.

Background technique

LED street lamp refers to the street lamp made of LED light source, has efficient, safety, energy-saving and environmental protection, service life length, response speed The particular advantages such as fast, the colour rendering index height of degree, have a very important significance city illumination energy conservation.

Road lighting and people's production and living are closely related, and with the quickening of Urbanization in China, LED street lamp is to orient Shine, power consumption is low, drive characteristic is good, fast response time, shock resistance height, long service life, the advantages such as environmentally protective by Gradually enter into the visual field of people, as the energy-conserving light source of new generation for most substituting conventional light source advantage in the world, therefore, the road LED Lamp will become the optimal selection of roadway illumination and energy saving transformation.

For LED street lamp unlike conventional street lamp, LED light source uses low-voltage DC supply, by GaN base power-type blue light The efficient white light that LED is synthesized with yellow has efficient, safety, energy-saving and environmental protection, service life length, fast response time, colour rendering index high Etc. particular advantages, can be widely applied to road.

LED street lamp has lot of advantages:

1, the characteristic of --- the one-way of light itself, the not diffusion of light guarantee light efficiency.

2, LED street lamp has unique secondary optical design, the region illuminated needed for the illumination of LED street lamp is mapped to, into one Step improves light efficiency, to reach energy saving purpose.

3, LED has reached 110-130lm/W, and there are also very big development space, theoretical value reaches 360lm/W.And high pressure The luminous efficiency of sodium vapor lamp is just increased with power increase, and therefore, overall light efficiency LED street lamp is stronger than high-pressure sodium lamp；(this is total Body light efficiency be it is theoretic, actually the light efficiency of 250W or more high-pressure sodium lamp be higher than LED light).

4, the light colour rendering of LED street lamp is more much higher than high-pressure sodium lamp, and high-pressure sodium lamp colour rendering index only has 23 or so, and LED Street lamp colour rendering index reaches 75 or more, considers from visual psychology angle, reaches equivalent brightness, the illuminance of LED street lamp averagely may be used To reduce by 20% or more than high-pressure sodium lamp,.

5, light decay is small, and 1 year light decay still reaches rto request less than 3%, using 10 years, and high-pressure sodium lamp light decay is big, and one Or so year has declined 30% or more, and therefore, LED street lamp can be lower than high-pressure sodium lamp in the design using power.

6, LED street lamp has automatic control energy-saving device, is able to achieve in the case of meeting different periods lighting requirement that maximum can The reduction power of energy saves electric energy.Computer light modulation, time segment control, light control, temperature control, automatic detecting can be achieved Deng humanized function.

7, the service life is long: can use 50,000 hours or more, provide quality assurance in 3 years.Shortcoming is exactly the service life of power supply It cannot be guaranteed.

8, light efficiency is high: use >=100LM or more chip, can 75% or more energy conservation relative to conventional high-tension sodium vapor lamp.

9, simple installation: burying cable without rectifier etc. without adding, and will directly be installed on lamp stand and connect or light source is embedding Cover original lamp housing.

10, radiating control is outstanding: summer temperature control is at 45 degree hereinafter, and using passive radiating mode, the heat dissipation in summer It ensures insufficient.

11, reliable in quality: circuit power all uses high quality component, and every LED has independent overcurrent protection, is not necessarily to Fear of damage.

12, it is photochromic uniformly: lens are not added, do not sacrificed with improving brightness uniformly it is photochromic, thus guarantee without aperture it is photochromic It is even.

13, LED is free of harmful mercury metal, will not cause damages to environment when scrapping.

In summary the LED street lamp energy-saving effect of principle is significant, can economize on electricity 60% or more instead of high-pressure sodium lamp.

But existing LED street lamp also has disadvantage: existing LED street lamp is once damaged, it is necessary to high altitude operation, high-altitude dimension It repairs very difficult, is not easy plug.
