Embodiment Construction

[0033] In specific implementation, the refrigerant heat dissipation chamber is first evacuated, then filled with propane, and then closed, and a pressure indicator is provided for regular inspection. The DC power is obtained from AC power transformation and rectification, and more than 2 sets of backup transformation and rectification circuits are set up. The DC power is stored and buffered by a super capacitor battery, which can improve the quality of the DC power.

[0034] The voltage in the high-voltage DC power supply line can be selected from 160 to 320V, which is obtained by transforming and rectifying the 220 to 380V AC power supply.

[0035] The photosensitive circuit is aimed at the sky, and the street lamp is turned on according to the sunlight intensity, and the circuit is a photovoltaic gate circuit.

[0036] The series-parallel switching circuit can switch the LED lamp beads in the LED lamp from 1-3 rows of energy-saving series mode to 2-6 rows of normal light-emi...

Abstract

The invention provides an intelligent LED (Light-Emitting Diode) street lamp. The intelligent LED street lamp is composed of an LED street lamp, a 160-320 V DC (Direct Current) power source and an intelligent controller, wherein the LED street lamp is composed of warm-colour linear optical glass, a refrigerant radiating cavity, a series-parallel switching circuit, a temperature control protection circuit and an LED lamp; and the intelligent controller is composed of an infrared sensor and a photosensitive resistor. Therefore, the circuit cost is lowered as the high-voltage DC electricity of a single wire can be utilized, and the high-quality DC electricity can be used intensively as a rectifier circuit of single LED lamp is replaced; the warm-colour linear optical glass can solve the colour and light spot problems efficiently; the refrigerant radiating cavity can radiate heat more efficiently; and energy can be saved and service life can be improved as the serial connection and the parallel connection can be switched freely.

Description

technical field [0001] The invention relates to a street lamp, especially an LED street lamp. Background technique [0002] Street lamps are an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps. High-pressure sodium lamps emit 360 degrees of light. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in my country has become increasingly prominent, and there has been a serious shortage of power supply. Energy conservation is an urgent problem to be solved. Therefore, the development of new high-efficiency, energy-saving, long-life, high color rendering index, and environmentally friendly LED street lamps is of great significance to energy-saving urban lighting. [0003] Road lighting is closely r...
