Abstract
The utility model discloses a light emitting diode (LED) street lamp with heat radiation fins and a connecting sleeve on an aluminum base plate, which comprises the aluminum base plate, wherein a plurality of heat radiation fins are fixedly arranged at the upper end of the aluminum base plate, the upper ends of the middle parts of the heat radiation fins are clamped and connected with the connecting sleeve, the connecting sleeve is connected to a lamp rod of the street lamp, the lower end of the aluminum base plate is provided with a plurality of LED light sources, optical lenses are covered outside the LED light sources, the back end of the aluminum base plate is provided with a power supply, all LED light sources are connected to the power supply, the LED light sources are LED lamps uniformly distributed on the surface of the aluminum base plate, and the power supply is a driving power supply capable of providing the constant-current power supply mode on the LED light sources. Through the structural mode of installing the heat radiation fins at the upper end of the aluminum base plate, installing the LED lamps at the lower end of the aluminum base plate and installing the power supply at the back end of lamp bodies, the utility model can effectively change the light ray distribution of high-power LED light sources, and can meet the road traffic illumination standard requirement. Because of the adoption of the constant-current power supply mode, the normal work of the LED can be ensured.
Description
Technical field:
The utility model relates to LED lighting apparatus field, the LED street lamp of band fin and adapter sleeve on a kind of specifically aluminium base.
Background technology:
Large power white light LED is as lighting source, with characteristics such as its energy-conserving and environment-protective, long-life, designability are strong, obtains increasingly extensive application in the road lighting field.LED self is not scorching hot body during work as the solid cold light source, but electric current flows through the resistance heat that produces when the PN of LED saves LED is heated up.Can be aging rapidly when LED at high temperature works, light efficiency descends, even loses efficacy.Slow down the light decay of LED, make the LED lamp that be arranged longer service life, must reduce the temperature of LED tube core, that is will resolve the heat dissipation problem of LED lamp.
In the road lighting field, national road pavement illumination has standard, need carry out luminous intensity distribution to the LED light fixture according to national standard and handle, to satisfy or to be higher than the requirement of reason illumination.
Summary of the invention:
For solving the problem that prior art exists, the spy provides the LED street lamp of being with fin and adapter sleeve on a kind of aluminium base, by fin being installed in the aluminium base upper end, the LED lamp is installed in the aluminium base lower end, and the frame mode of power supply is installed in the lamp body rear end, and can effectively change the distribution of light of high-power LED light source, satisfy the requirement of road traffic lighting criteria, owing to adopt the powering mode of constant current, guaranteed the operate as normal of LED.
The scheme that the utility model adopts:
The LED street lamp of band fin and adapter sleeve on a kind of aluminium base comprises aluminium base: the aluminium base upper end is installed with some fin, and upper end, fin middle part is connected with adapter sleeve, and adapter sleeve is connected to street lamp post; The aluminium base lower end is equipped with some led light sources, and led light source is surrounded by optical lens outward; The aluminium base rear end is equipped with power supply, and described each led light source all is connected to power supply.
Described led light source is the LED lamp, evenly distributes on the aluminium base face; Described adapter sleeve is from middle dimidiation, but the metallic cylinder of folding; Described optical lens is the optical lens of 50*120 degree; Described power supply is for carrying out the driving power of constant current powering mode to led light source.
Advantage of the present utility model is:
The utility model is by installing fin in the aluminium base upper end, the LED lamp is installed in the aluminium base lower end, and the frame mode of power supply is installed in the lamp body rear end, can effectively change the distribution of light of high-power LED light source, satisfy the requirement of road traffic lighting criteria, owing to adopt the powering mode of constant current, guaranteed the operate as normal of LED.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
The LED street lamp of band fin and adapter sleeve on a kind of aluminium base, comprise aluminium base 1: aluminium base 1 upper end is installed with some fin 2, and upper end, fin 2 middle parts is connected with adapter sleeve 3, and adapter sleeve 3 is connected to street lamp post; Aluminium base 1 lower end is equipped with some led light sources 4, the led light source 4 outer optical lenses 5 that are surrounded by; Aluminium base 1 rear end is equipped with power supply 6, and each led light source 4 all is connected to power supply 6; Led light source 4 is the LED lamp, evenly distributes on 1 of aluminium base; Adapter sleeve 3 is from middle dimidiation, but the metallic cylinder of folding; Optical lens 5 is the optical lens of 50*120 degree; Power supply 6 is for carrying out the driving power of constant current powering mode to led light source 4.
