Description
Technical field
The utility model relates to LED projector lamp technical field, particularly relates to a kind of flood light lightning protection device.
Background technology
Flood light is the light fixture of the projecting environment of illumination of specifying on face to be illuminated, also known as spotlight, most employing great power LED is as its light source, and LED projector lamp of the prior art is due to the particularity of installation site, all be contained in open air, itself is also vulnerable to the impact of thunder and lightning natural calamity, very easily suffers broken by lightning.
Summary of the invention
The problem that the utility model pin will solve is to provide a kind of safety and stability, extends the flood light lightning protection device in flood light useful life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flood light lightning protection device, comprises housing, lid, PCB, voltage clamp bit-type Transient Suppression Diode, gas discharge tube, high molecular polymer positive coefficient temperature and resistance and power line; Described PCB is arranged in housing, described voltage clamp bit-type Transient Suppression Diode, gas discharge tube and high molecular polymer positive coefficient temperature and resistance all arrange and are connected in PCB, described power line one end is connected with PCB, the other end stretches out housing, described lid and housing match, and are buckled on housing.
Described lid and housing joint are provided with sealing strip.
Described lid and hull outside are provided with insulating barrier.
Owing to adopting technique scheme, (1) gas discharge tube arranged in this lightning protection device works release Lightning Transient overcurrent and over-voltage effect, and insulation resistance is very large, and parasitic capacitance is very little, and carrying out surge protection ability is strong; (2) voltage clamp bit-type Transient Suppression Diode, i.e. TVS pipe is FV, utilize the protection that overvoltage clamper realizes late-class circuit to a lower magnitude of voltage by its nonlinear characteristic, TVS pipe is convenient to integrated, is well suited for using on veneer, and its useful life is relatively long; (3) high molecular polymer positive coefficient temperature and resistance; i.e. PPTC; PPTC device uses as series components in circuit; mechanical shock and vibrations can be tolerated; thus contribute to providing reliable protective capability in range of application widely, when temperature rises to certain value, the resistance value of PPTC by increasing to 3 to 4 orders of magnitude; the amount of current flowed through under fault condition can be reduced to a lower steady-state level by this resistance value after increase, thus the equipment in protective circuit.Setting of the present utility model, for flood light provides complete full guard pattern, can accept repeatedly thunder and lightning repeated stock in the short time, leakage current is little, residual voltage is low; Shell is while insulation, and adopt sealing strip to seal, waterproof moisture-proof effect is good.
The beneficial effects of the utility model are: have lightning protection, safety and stability, the advantage increased the service life.
