Description
Technical field
The utility model relates to holder of miner's lampe, exactly is the holder of miner's lampe with heat abstractor.
Background technology
Along with the development of LED technology and in the extensive use of lighting field, there are many enterprises constantly to drop into the developmental research of led light source mine lamp in recent years, LED is applied in holder of miner's lampe, its constant current constant voltage power supply realizes easily by electronic circuit, difficult point just is heat dissipation problem, especially under the situation that constantly improves, improves constantly at LED lumen number, radiating condition is also promoted gradually, this requires the heat radiation of LED bottom to want fast, want absolute reliable, otherwise the too high meeting of temperature causes internal structure to deform, and influence is normally used, and its normal temperature should be below 45 degree.But owing to holder of miner's lampe adopts hermetically-sealed construction, the volume of cavity is less, and shell of lamp base is a plastic material, is unfavorable for heat radiation, so prior art can only be covered the long-pending next heat radiation requirement of satisfying of copper face by increasing printed circuit board.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of holder of miner's lampe with heat abstractor.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of holder of miner's lampe with heat abstractor, comprise lamp head ring, lamp housing, lamp surface glass, reflector, light emitting diode, circuit board and heat abstractor, described heat abstractor is by heat-dissipating aluminium plate, heat radiation aluminium bar and radiator are formed, light emitting diode is arranged on the heat-dissipating aluminium plate, the below of heat-dissipating aluminium plate is a circuit board, be separated with a segment distance between the two mutually, the payment to a porter of light emitting diode is connected with circuit board, the heat radiation aluminium bar is positioned at the below of heat-dissipating aluminium plate, its upper end is connected with heat-dissipating aluminium plate, the lower end is connected with radiator, and radiator is embedded in the louvre at lamp housing rear portion, and its radiating surface is towards the lamp housing outside and connect hatpin.
The upper end of described heat radiation aluminium bar is connected by screw with heat-dissipating aluminium plate.
The lower end of described heat radiation aluminium bar is inserted in the middle of the endoporus of radiator.
Offer multiple tracks heat radiation groove on the radiating surface of described radiator.
Described radiator is and cuts the cuboid that a dihedral becomes inner top surface.
The inner top surface of described radiator parallels with heat-dissipating aluminium plate, offers locating hole on it.
Described heat radiation aluminium bar is vertical to be arranged and perpendicular to heat-dissipating aluminium plate.
Described circuit board is provided with through hole or the breach that passes for the heat radiation aluminium bar.
Leave on the described hatpin and the corresponding breach of the radiating surface of radiator.
The utility model is fixed on light emitting diode (LED) on the heat-dissipating aluminium plate, heat-dissipating aluminium plate is connected with radiator on being fixed on housing wall by the heat radiation aluminium bar of its below again, so not only can utilize three aluminium parts to be its heat radiation, because the radiating surface of radiator is towards the outside, therefore can also constantly carry out heat exchange, further promote heat dispersion with the external world.After using this heat abstractor, the lamp holder internal temperature is below 35 degree, and before not using, internal temperature is usually more than 50 degree, reach as high as 70 degree, not only reduced cost, increased service life of each critical piece in the lamp holder, and safe and reliable, function admirable.
