Single-lamp self-control power-saving high-power LED (light-emitting diode) road lamp radiating under assist of refrigerant

Abstract

The invention discloses a single-lamp self-control power-saving high-power LED (light-emitting diode) road lamp radiating under assist of refrigerant and relates to the technical field of LED road lamps; a light source cavity is formed at one end of an LED road lamp main shell; a rainproof upper cover provided with radiating fins is coveted above the light source cavity; a light-transmitting lower cover is buckled below the light source cavity; the road lamp is characterized in that the LED luminous body is screwed at the top part of the light source cavity in a matrix form by a universal ball joint; the other end of the main shell is further provided with a micro compressor and a drive control device which controls the on-off of the micro compressor; the micro compressor performs cold-circulating radiating on the upper surface of the top part of the LED light source by a refrigerant coiled pipe. According to the single-lamp self-control power-saving high-power LED road lamp, the extremely-high-temperature environment is conquered by means of the refrigerant at the same time with the using of the traditional radiating mode, the three light distributions are realized by the universal joint, and the illuminating power density is reduced under the condition that the illuminating evenness is met, thereby saving energy. The road lamp is scientific and novel in structure and solves the radiating and illuminating evenness problems of the LED road lamp thoroughly.

Description

technical field [0001] The invention relates to the technical field of LED street lamps, in particular to a single-lamp self-control energy-saving high-power LED street lamp which utilizes a refrigerant to assist heat dissipation and can exert high heat dissipation efficiency and power saving rate in extreme environments. Background technique [0002] The energy crisis and environmental protection have always troubled people all over the world, and China, which is in the period of rapid economic development, has increasingly felt the importance and urgency of saving energy. Lighting electricity consumption, which accounts for nearly one-fifth of my country's total electricity consumption, is an important part of my country's energy-saving work. In lighting electricity consumption, street lamps occupy a considerable share. The number of street lamps is large, the line working time is long, and the overall energy consumption is quite large, so the energy-saving control of str...

Problems solved by technology

Among them, although natural convection heat dissipation has many advantages such as simple structure, low heat dissipation cost, and uniform heat dissipation, this heat dissipation method cannot meet all usage environments, such as: high-temperature nighttime environment, and environment where air convection is not obvious near buildings; and, The forced heat dissipation structure of adding a fan is more complicated, and maintenance is difficult; there are various internal conduction heat dissipation structures, but there are not many effective conduction heat dissipation structures
