The high-heat-dissipation LED explosion-proof lamp is characterized in that a heat-conducting column is arranged in the center of the radiator; the LED chip is fixed on the heat-conducting column; and heat-dissipating fins are arranged around the radiator in the diffused shape. Due to the fact that the heat-conducting column is arranged in the center of the radiator; the LED chip is fixed on the heat-conducting column, and heat-dissipating fins are arranged around the radiator in the diffused shape, heat emitted by the LED chip is transferred to the heat-dissipating fins through the heat-conducting column to be dissipated. Therefore, the heat dissipation efficiency of the LED explosion-proof lamp is improved and the service life of the LED chip is greatly prolonged. The high-heat-dissipation LED explosion-proof lamp has the advantages of high heat dissipation efficiency and long service life.
Description
Technical field
The present invention relates to a kind of LED lighting, relate to a kind of LED explosion-proof lamp of high heat dispersion specifically.
Background technology
Explosion-proof lamp is meant the light fixture for the various certain measures that prevent to light explosive mixture on every side such as explosive gas atmosphere, explosive dust atmosphere, methane gas etc. and take.Very important explosion-proof principle is exactly the temperature on the restriction case surface, component surface or the electronic devices and components surface that contact with damp, explosive dust in the explosion-proof lamp, and limits electric contact surface temperature and be lower than its minimum ignition temperature or ignition temperature.
Because LED belongs to solid-state cold light source, have the electro-optical efficiency height, caloric value is little, power consumption is little, operating voltage belongs to advantages such as safe low-voltage, long service life, so large power white light LED is the preferred light source of explosion-proof lamp; Simultaneously, for satisfying above-mentioned requirements, lamp socket must have rational radiator structure and light fixture is carried out rational luminous intensity distribution.Traditional explosion-proof lamp light source and the power supply Room that exists together, the heat that produces in power supply and the light source works process adds up, and causes the lamp casing surface temperature to raise, and causes the led light source operating temperature to surpass node temperature and loses efficacy; And the power supply temperature raises possibly cause static and electric spark, when casing surface temperature is higher than its minimum ignition temperature or ignition temperature, probably blasts.
The explosion-proof high-efficiency energy-saving long-life life light fixture of prior art generally all adopts gas-discharge light source and Novel LED light source.The defective of gas-discharge light source is that caloric value is high, and power consumption is big, and the life-span is short, and cost is high, safeguards frequent; Novel LED light source has unidirection luminous, and light utilization efficiency is high, high light efficiency; High-color rendering, the long-life, energy-conservation; Environmental protection, advantage such as non-maintaining, but most of radiator structure can not be effectively distributes the temperature of chip; Cause chip center's temperature too high, thereby influenced its serviceability the service life that has reduced light fixture, and increased use cost.
Summary of the invention
Technical problem to be solved by this invention provides the LED explosion-proof lamp of the high heat dispersion of a kind of radiating efficiency height, long service life.
The present invention solves above-mentioned technical problem through following technical proposals: a kind of LED explosion-proof lamp of high heat dispersion; Comprise lamp socket, be fixed on radiator on the lamp socket, be installed in led chip on the radiator, be arranged on reflector around the led chip and the diffuser that is fixed on the led chip light direction; It is characterized in that: the center of said radiator is provided with a heating column; Said led chip is fixed on the said heating column, is provided with the radiating fin that is diverging around the said radiator.
Preferably, said reflection shield be provided be used to dispel the heat to discharge orifice.
Preferably, said discharge orifice is arranged on the radiating fin root near radiator.
The present invention with prior art beneficial effect mutually is: owing to be provided with a heating column at the center of radiator, led chip is fixed on the said heating column, is provided with the radiating fin that is diverging around the radiator.The heat that led chip sends passes to said radiating fin heat radiation through heating column, has improved the radiating efficiency of LED explosion-proof lamp, has prolonged the service life of led chip greatly.The present invention has the advantage of radiating efficiency height, long service life.
Description of drawings
Just the present invention is described further with implementing below in conjunction with accompanying drawing:
Fig. 1 is a contour structures sketch map of the present invention.
Fig. 2 is a partial sectional view of the present invention.
Fig. 3 is a upward view of the present invention.
The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
With reference to accompanying drawing 1, Fig. 2, shown in Figure 3; The present invention includes lamp socket 1, be fixed on radiator 2 on the lamp socket 1, be installed in led chip 5 on the radiator 2, be arranged on reflector 4 around the led chip 5 and the diffuser 6 that is fixed on led chip 5 light directions; The center of said radiator 2 is provided with a heating column 3; Said led chip 5 is fixed on the said heating column 3, is provided with the radiating fin 8 that is diverging around the said radiator 2.Said reflection shield 4 be provided be used to dispel the heat to discharge orifice 7, said discharge orifice 7 is arranged on radiating fin 8 roots near radiator 2.Heating column 3 closely is connected with radiator 2; Heating column 3 conducts to heat on the radiator 2; Radiator 2 adopts the diverging radiator structure that is made up of a plurality of radiating fins; As shown in Figure 1, this structure can increase the area of dissipation of radiator, and the heat that can fast heating column 3 conduction be come is dispersed in the air; The version of reflector 4 is when satisfying the light usable reflection; Owing to satisfy the light usable reflection is that those skilled in the art realize easily, so repeat no more, inner ring has a circle cross-ventilation hole 7; As shown in Figure 3; Promptly this cross-ventilation hole 7 is positioned at that end near the radiating fin root of radiator 2, can flow the heat of radiating fin 8 roots on the radiator 2 and the cross-ventilation below the reflector 4 in this cross-ventilation hole 7 thereby accelerate air; Reduce the temperature of fin 2, reduce the temperature of led chip 5 with this.Diffuser 4 is installed on the fin 2 through screw or other modes well known to those skilled in the art, when satisfying printing opacity, satisfies requirement of explosion proof.In addition, the surface of diffuser 6 is the seam explosion suppresion surface, led chip 5 is completely cut off with outside, and have explosion prevention function.
The present invention adopts large power long life-span environment protecting and power-saving led light source, and this light source is installed on the radiator of special radiator structure, to reach good heat conduction and heat radiation, guarantees the led light source operate as normal.Because the durable energy saving of led light source life characteristic has guaranteed the work of explosion-proof lamp high-efficiency energy-saving long-life life.Owing to be provided with a heating column at the center of radiator, led chip is fixed on the said heating column, is provided with the radiating fin that is diverging around the radiator.The heat that led chip sends passes to said radiating fin heat radiation through heating column, has improved the radiating efficiency of LED explosion-proof lamp, has prolonged the service life of led chip greatly.The present invention has the advantage of radiating efficiency height, long service life.
The above, is familiar with this technological various simple covert and modification that those skilled in the art did and still belongs to protection scope of the present invention in the spiritual category that does not break away from the present invention's creation only so that the present invention conveniently to be described.
