Along with the development of LED technology, LED is not only applied to the special lighting such as indicator lamp, backlight field, and starts to be widely used in various general lighting field as the substitute of incandescent lamp, electricity-saving lamp.The advantages such as LED has that the life-span is long, light efficiency is high, radiationless and low energy consumption, belonging to energy-conservation environmental protection illumination, is therefore that the LED of light source continues to bring out with LED.
At present, common LED lamp is all configured with heat abstractor.The LED chip of conventional LED bulb is only limited in by aluminium base and working of plastics distributes the heat that LED lamp produces, and this can't resolve the heat dissipation problem of LED bulb certainly.Therefore be necessary to propose the better LED bulb of a kind of radiating effect.
Utility model content
Main purpose of the present utility model is the radiator structure providing a kind of LED bulb, and this structure is simple, easy for installation, better heat-radiation effect.
Above-mentioned purpose is achieved by the following technical solution:
A kind of radiator structure of LED bulb, comprise lamp socket, working of plastics, radiator, PCB, LED chip and lampshade, lamp socket and working of plastics are installed together, radiator is arranged on the bottom surface of working of plastics, some radiating fins are down stretched out in the bottom surface of radiator, and form heat dissipation wind channel between adjacent two radiating fins, PCB is arranged on the bottom surface of radiating fin by semiconductor chilling plate, LED chip is electrically connected with PCB, together with lampshade is hermetically sealed with described working of plastics.
Radiator described above adopts aluminium die casting to form.
The inner surface of lampshade described above scribbles fluorescent material.
The quantity of LED chip described above is two, and LED chip is that welded and installed is in PCB.
The material of lampshade described above is Merlon.
Lamp socket described above and working of plastics are threaded connection and are installed together.
The utility model compared with prior art tool has the following advantages:
1) radiator is arranged on the bottom surface of working of plastics, some radiating fins are down stretched out in the bottom surface of radiator, heat dissipation wind channel is formed between adjacent two radiating fins, PCB is arranged on the bottom surface of radiating fin by semiconductor chilling plate, LED chip is connected with PCB, together with lampshade is hermetically sealed with described working of plastics, this structure is simple, the heat that LED chip produces is conducted outward by semiconductor chilling plate, radiating fin, heat dissipation wind channel and working of plastics, greatly can improve the radiating effect of LED bulb, be beneficial to LED bulb and work long hours;
2) radiator adopts aluminium die casting to form, and production technology is simple, and the heat conduction of aluminium, heat dispersion are better;
3) inner surface of lampshade scribbles fluorescent material, can improve the illuminating effect of LED bulb to a certain extent;
4) quantity of LED chip is two, and illuminating effect is better, LED chip be welded and installed in PCB, production technology is simple, technology maturation, and cost is low.
Accompanying drawing explanation
Fig. 1 is the stereogram of LED bulb in embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the present embodiment is a kind of radiator structure of LED bulb, comprise lamp socket 1, working of plastics 2, radiator 3, PCB 4, LED chip 5 and lampshade 6, lamp socket 1 and working of plastics 2 are threaded connection and are installed together, the mounting means assembling be threaded connection is simple, quick, and the connection between lamp socket 1 and working of plastics 2 is reliable, avoids due to be connected between lamp socket 1 with working of plastics 2 unreliable and cause loose contact, the bad phenomenon that LED bulb does not work.Radiator 3 is arranged on the bottom surface of working of plastics 2, the bottom surface of radiator 3 is down stretched out some radiating fins 31, heat dissipation wind channel 32 is formed between adjacent two radiating fins 31, PCB 4 is arranged on the bottom surface of radiating fin 31 by semiconductor chilling plate 7, LED chip 5 is electrically connected with PCB 4, together with lampshade 6 is hermetically sealed with described working of plastics 2, avoid outside air to enter into inside lampshade 6 and damage is caused to the PCB 4 inside lampshade 6 and LED chip 5, improve its reliability, extend its service life.The heat that LED chip 5 produces is conducted outward by semiconductor chilling plate 7, radiating fin 31, heat dissipation wind channel 32 and working of plastics 2, greatly can improve the heat-sinking capability of LED bulb, be beneficial to LED bulb to work long hours, radiating efficiency at least improves 60% compared to existing LED bulb.
The maximum control temperature difference of semiconductor chilling plate 7 reaches 70 degrees Celsius, and temperature control mode adopts fully-automatic intelligent PID power control system, variable frequency adjustment, temperature continuously adjustabe.
Radiator 3 adopts aluminium die casting to form, the heat conduction of materials of aluminum, perfect heat-dissipating, effectively improves the heat-sinking capability of LED bulb.
The inner surface of lampshade 6 scribbles fluorescent material, can improve the illuminating effect of LED bulb to a certain extent, makes LED bulb provide softer, more uniform light.
The cross section of lampshade 6 is circular arc, can be specifically other arcs of semicircular arc, ellipse arc etc., because arc is conducive to producing softer, more uniform light.
The quantity of LED chip 5 is two, LED chip 5 be welded and installed in PCB 4, use two LED chip 5 to be conducive to increasing the brightness of LED bulb, and two LED chip 5 are symmetrical, are beneficial to provide more uniform light.
The quantity of LED chip 5 can be one, two, three etc., in this embodiment preferably two.
The material of lampshade 6 can be selected from Merlon, polymethyl methacrylate, the polyacrylic one that the art personnel know, the material of preferred lampshade 6 is Merlon, because the source of Merlon is more extensive and cost is relatively cheaper, and there is excellent physical property, be more suitable for LED bulb.
