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 switch of LED street light is mainly controlled by remote control network and infrared sensor.

[0037] The series-parallel switching circuit can switch ...

Abstract

The invention provides an Internet of things LED street lamp which is composed of an LED street lamp body, a high-voltage direct-current power circuit and a network sensor. The LED street lamp body is composed of warm-color linear optical glass, a coolant heat dissipation cavity, a series-parallel connection switching circuit, a temperature-control protection circuit and an LED lamp. The network sensor is composed of an infrared inductor, a remote control network and a photosensitive circuit. The warm-color linear optical glass covers the light face of the LED lamp which is pasted to the coolant heat dissipation cavity through hot-melting heat-conductive silica gel, so that linear high-voltage direct currents can be used, circuit cost is reduced, a rectification circuit of a singular LED lamp is replaced, and the high-quality direct currents are used in a concentrating mode. The warm-color linear optical glass can effectively solve the problems of colors and light spots, the coolant heat dissipation cavity can efficiently dissipate heat, serial connection and parallel connection can be switched freely, energy can be saved, and service life is prolonged.

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...
