Abstract
The utility model relates to a street lamp taking the semiconductor LED as the light source. The utility model is characterized by: the light source of the street lamp is the constant flow switch power source communicated by the rectifier filter circuit, and voltage stabilizing diode and constant flow source LM317, the street lamp has the advantages of high luminous efficiency, small electric power consumption, and long life service, and is a green environmental protective light source.
Description
Technical field
The utility model relates to the light fixture-street lamp of city, road night illumination.
Background technology
The light source that existing street lamp uses mostly is incandescent lamp or sodium vapor lamp etc., and its power consumption is big, is the vehement bulb of heat, and heat dissipation capacity is big, and service life is short, does not meet environment protection requirement.The semiconductor light-emitting-diode of Chu Xianing is a kind of cold light source device that can directly electric energy be converted into visible light in recent years, has that operating voltage is low, power consumption is little, luminous efficiency is high, extremely weak point, shock resistance, vibration resistance, stable and reliable for performance, photochromic pure, nontoxic, harmless a, advantage such as volume is little of response time.But single brightness is limited, only several watts of maximums, and illuminating effect is very poor.
Summary of the invention
The utility model is exactly a kind of Semiconductor light-emitting diode streetlight that designs at the shortcoming of existing street lamp.It is made up of light fixture on lamp stand and the lamp stand and light source.Light source is a plurality of light emitting diodes that are connected with the constant current switch power supply.The constant current switch power circuit is formed by connecting by current rectifying and wave filtering circuit and voltage regulation resistance and constant-current source LM317.Light emitting diode is many series-parallel light emitting diode cluster of lamps, ornamental, each cluster of lamps, ornamental current-sharing current-limiting resistance of connecting respectively.It is light source that the utility model street lamp adopts LED, has advantages such as luminous efficiency height, power consumption is little, the life-span is long, and brightness can be satisfied the street lamp requirement.Owing to be cold light source, thereby be the ideal green light source, compliance with environmental protection requirements.
