Description
Technical field
The present invention relates to a kind of heat radiation of high-power electronic product, particularly relate to a kind of design of radiator structure of LED bulb lamp.
Background technology
LED illumination as the 4th generation lighting engineering, compare it with traditional incandescent lamp, electricity-saving lamp and have light efficiency height, environmental protection, long, high directivity of life-span, the advantages such as colour rendering is good, be widely used in demonstration, decoration, road and some special lighting fields, yet the electricity conversion of LED only reaches 10-20%, and the power conversion of about 80-90% heat is if untimelyly remove heat, the hydraulic performance decline that will cause light source affects life-span of LED.
In existing LED illuminating and heat radiating technology, usually utilize transfer of heat that radiator produces led chip in environment, the material of heat radiation generally is aluminium, copper or other Heat Conduction Material, for high-power LED lamp, the fair volume of radiator is larger, relatively heavier, also there is the bad shortcoming of air permeability simultaneously, affected the radiating effect of radiator.The heat radiation that existing LED asks bubble lamp heat dissipation design also seldom to take full advantage of lampshade reduces the weight of LED radiator own, so cost is higher.
Summary of the invention
The object of the invention is to overcome the shortcoming that present LED bulb lamp heat dissipation design exists, the efficient LED bulb lamp of a kind of LED radiator structure is provided.
The present invention utilizes the unidirectional high thermal conductivity of carbon fiber of present material and the heat dispersion of lampshade, the heat that led chip produces can be removed rapidly, reduces the temperature of led chip, and it is being worked in normal temperature range.
In order to realize above-mentioned purpose, the present invention proposes following technical scheme:
A kind of LED ball bulb lamp structure comprises carbon fiber pipe, radiator, pcb board, led chip, lens and lampshade; Described radiator inside is hollow, is arranged in the lampshade; A plurality of carbon fiber pipes be arranged on radiator hollow in, the radiator side has a plurality of air vents; Carbon fiber pipe one end is connected with the bottom substrate of radiator, and the other end runs through the radiator top, is connected with lampshade; Radiator is connected with pcb board, and led chip is installed on the pcb board, and lens are connected with the bottom of radiator.
For further realizing the object of the invention, described carbon fibre tube is selected the high thermal conductivity coefficient asphalt base carbon fiber material of MitsubishiK13D2U, and diameter is between 2-10mm.
The number 9-15 of described air vent, the width of air vent is 3-5mm, highly is 20-50mm.
The wall thickness of described radiator is 3-5mm.
Described radiator top drilling, the aperture is between 2-10mm.
Described radiator top center also is provided with circular hole.
Described led chip is arranged on concentric circles of pcb board.
Described lens are hemispherical, are connected by the mode that spins with the bottom of radiator.
Relatively existing technology, foregoing invention has following advantage:
1) used carbon fiber pipe of the present invention is a kind of high thermal conductivity coefficient material.The heat that led chip produces is passed to carbon fiber pipe by the bottom of pcb board, radiator; Because carbon fiber pipe is a kind of high thermal conductivity coefficient material, its thermal conductivity factor is much larger than the thermal conductivity factor of aluminium and copper product, it can pass to heat bottom and the lampshade of radiator rapidly, by lampshade and radiator heat is being delivered in the surrounding air, can effectively reduce the temperature of led chip, reach the requirement of temperature control;
2) radiator of the present invention inside is hollow, has saved the material of using of radiator; The material of radiator can plastics or other Heat Conduction Material, saves the cost of radiator; The side opening of heat radiation air vent, can increase flowing of radiator inner air, improve the heat dispersion of heat radiation;
3) lampshade of the present invention is connected with carbon fiber pipe, the heat of carbon fiber pipe transmission can be rapidly surface by lampshade be lost in the air, reduced the thermic load of heat radiation; The surface of lampshade can spray heat loss through radiation coating increases its surperficial heat dispersion; The surface of lampshade can increase some art patterns, improves the art appreciation of light fixture; Simultaneously because lampshade can prevent that to radiator dust from the gathering of heat radiation, having avoided affecting gathering of radiator owing to dust the performance of radiator; Lampshade is the effect that hemispherical can play optically focused.
Description of drawings
The schematic diagram of Fig. 1 LED ball bulb lamp structure of the present invention.
Shown in the figure: led chip 1, air vent 2, carbon fiber pipe 3, radiator 4, lampshade 5, lens 6 and pcb board 7.
Concrete embodiment
The LED bulb lamp that a kind of LED ball bulb lamp structure is a kind of high efficiency and heat radiation comprises carbon fiber pipe 3, radiator 4, pcb board 7, led chip 1, lens 6 and lampshade 5.Radiator 4 is cylindric, and inside is hollow, is arranged in the lampshade 5; Carbon fiber pipe 3 be arranged on radiator 4 hollow in, carbon fiber pipe 3 one ends are connected with the bottom substrate of radiator 4, the other end runs through radiator 4 tops, and is connected with lampshade 5; The bottom of radiator 4 is connected with pcb board 7 by the heat-conducting glue of high thermal conductivity coefficient, and led chip 11 is installed on PCB 7 plates, and preferably all led chips 1 are arranged on the concentric circles; Lens 6 are hemispherical, are connected by the mode that spins with the bottom of radiator 4;
