LED street lamp, Tunnel Lamp that present society is pushed away are main with monoblock type mainly; Be being made of one such as lamp plate and radiating subassembly, power supply; Applying unit need be removed original street lamp when changing, and then loads onto integral LED street lamp or Tunnel Lamp, and this has just increased replacement cost greatly; Simultaneously also increased the difficulty of maintenance, maintenance, this is the main cause that slowly pushes away not open of LED street lamp, Tunnel Lamp just also.
Summary of the invention:
The purpose of the utility model is to provide a kind of LED street lamp, Tunnel Lamp.
It comprises the lamp housing that is provided with the afterbody contact, and lamp holder is heat sink through lampshade and light source that the link screw connects; Driving power is set in the link connects the input that is located at basic onboard led small electric bulb in the lampshade through lead.
Spring is set in the lamp holder.
The center of link one side is provided with the locking slot fastening with lamp holder.
The outside of link connects two half-round clamping rings through screw.
The two ends that light source is heat sink are provided with the angle covering of the fan; Its angle covering of the fan angle is greater than 120 °
Infrared radiant material spraying, the about 0.05mm-0.5mm of thickness are adopted in the back side that light source is heat sink;
Driving power adopts following the electrical connection: civil power 220V connects rectification circuit; The rectification circuit output cathode connects overtemperature protection LVR, piezo-resistance Rym one end; The overtemperature protection LVR other end connects high-frequency filter capacitor C1, low frequency filtering capacitor C 2, current-limiting resistance Rx; It is anodal that the current-limiting resistance Rx other end connects light emitting diode Ri, and the rectification circuit negative pole connects Rym, high-frequency filter capacitor C1, low frequency filtering capacitor C 2 other ends and light emitting diode Ri negative pole.
The utlity model has the light conversion efficiency height, energy-conserving and environment-protective, no noxious material, power consumption is lower than more than 40% of conventional high-tension sodium vapor lamp, and the heat of the luminous generation of LED is little, be convenient to produce in batches, be convenient to change advantages such as upgrading, transformation.Adopt the power protection module of specialty simultaneously, the LED light fixture of avoiding unusual fluctuations such as thunder and lightning to cause damages.The heat accumulation of LED makes the led light source can efficient and long life work.Owing to adopt the separate modular design, can replace original conventional light source very easily, the same use occasion of using at original high-pressure mercury lamp and Metal halogen lamp; Improved the convenience of maintenance, management greatly.
