Abstract
The invention discloses a hot runner housing bulb lamp which comprises a lamp shade, an aluminum substrate, a heat conduction board, a radiator, a housing and a joint, wherein lamplight is arranged on the aluminum substrate; the rear end face of the aluminum substrate is connected with the heat conduction board; the radiator is arranged on the heat conduction board; the aluminum substrate, the heat conduction board and the radiator are arranged in the housing after formed; the lamp shade is arranged at the front end of the housing; the rear end of the housing is connected with the joint; the rear end of the joint is connected with a threaded connector; a gap is formed at a connecting part of the lower end face of the housing and the lamp shade; hot runners are formed in the lower end face of the housing; hot runner holes are formed in the upper end face of the housing; a plurality of hot runners are formed in the joint connected with the rear end of the housing; the hot runner holes are communicated with the joint; convection is formed between the upper hot runners and the lower hot runners; and a power supply placing bin is arranged in the housing. The hot runner housing bulb lamp overcomes defects of the prior art, and is simple in design and reasonable in structure, and the hot runners and the hot runner holes are formed in the housing, and communicated with the hot runners in the joint to form the vertically opposite convection, so that the heat in a lamp body is exchanged with the outside quickly.
Description
Technical field
The present invention relates to the bulb lamp technical field, specifically belong to a kind of hot flow path shell bulb lamp.
Background technology
The lampshade of existing LED bulb lamp is Totally-enclosed-type, and LED itself is a photoelectric device, there is a large amount of electric energy can be converted into heat energy in the course of the work, make the temperature of LED bulb raise, radiating effect is poor, damage led chip easily, reduced the quality of bulb, shortened the service life of bulb.Therefore radiator structure is comparatively key technology of lamp body, existing LED bulb lamp radiator and the moulding of many aluminium alloy compression castings of shell body, mostly be direct contact heat radiation, radiating effect is not ideal enough, the lamp body overall weight is bigger, and cost of manufacture is higher, because directly the radiator structure radiating effect is undesirable, can not adopt plastic casing, increase housing manufacture craft difficulty simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of hot flow path shell bulb lamp, the deficiencies in the prior art have been overcome, simplicity of design, rational in infrastructure, by hot flow path and hot flow path hole are set on the shell body, like this with joint on hot flow path be communicated with to form a relative convection current up and down, heat in the lamp body exchanges with extraneous fast, plastic casing can realize that appearance color is abundant, and manufacture craft is simple, and cost of manufacture is low.
The technical solution used in the present invention is as follows:
A kind of hot flow path shell bulb lamp, comprise lampshade, aluminium base, heat-conducting plate, radiator, shell body and joint, aluminium base is provided with light, described aluminium base rear end face connects heat-conducting plate, radiator is arranged on the heat-conducting plate, aluminium base, heat-conducting plate and radiator are arranged in the shell body after forming, the shell body front end is provided with lampshade, the rear end jointing, joint rear end connecting thread interface, shell body lower surface and lampshade junction are provided with the gap, and described shell body lower surface has hot flow path, and the upper surface has the hot flow path hole, the joint that connects in the shell body rear end has a plurality of hot flow paths, the hot flow path hole is communicated with joint, on, form convection current between the following hot flow path, have the power supply place position in the described shell body.
Described shell body is that plastics are made.
Described radiator is cylindrical structure, has protruding cylinder on the heat-conducting plate, and radiator is arranged on the cylinder.
A plurality of hot flow paths evenly distribute by circumferencial direction on the described joint.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention is by arranging hot flow path and hot flow path hole on the shell body, like this with joint on hot flow path be communicated with and form a relative convection current up and down, the heat in the lamp body and extraneous exchange fast, manufacture craft is simple, cost of manufacture is low.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is internal structure schematic diagram of the present invention;
Fig. 3 is another internal structure schematic diagram of the present invention.
The specific embodiment
Referring to accompanying drawing, a kind of hot flow path shell bulb lamp comprises lampshade 1, aluminium base 2, heat-conducting plate 3, radiator 4, shell body 5 and joint 6, and aluminium base 2 is provided with light, and shell body 5 is made for plastics.Aluminium base 2 rear end faces connect heat-conducting plate 3, radiator 4 is arranged on the heat-conducting plate 3, aluminium base 2, after forming, heat-conducting plate 3 and radiator 4 be arranged in the shell body 5, shell body 5 front ends are provided with lampshade 1, rear end jointing 6, joint 6 rear end connecting thread interfaces 7, shell body 5 lower surfaces and lampshade 1 junction are provided with the gap, described shell body 5 lower surfaces have hot flow path 501, the upper surface has hot flow path hole 502, and the joint 6 that connects in shell body 5 rear ends has a plurality of hot flow paths 501, and hot flow path hole 502 is communicated with joint, on, form convection current between the following hot flow path, have power supply place position 503 in the described shell body 5.Radiator 4 is cylindrical structure, has protruding cylinder 301 on the heat-conducting plate 3, and radiator 4 is arranged on the cylinder 301, and a plurality of hot flow path 501 evenly distributes by circumferencial direction on the joint 6.
Claims (4)
