Description
Technical field
This utility model relates to a kind of lighting, specifically a kind of convection heat emission type bulb lamp.
Background technology
LED lamp owing to having that profile is flexible, brightness big, the feature such as saves energy, environmentally friendly and applied range,
Make its market share occupied in illumination market increasing.But, during along with the use of LED, LED
The heat dissipation problem of light fixture, and LED light declines, and becomes a restriction LED service life and the key factor of LED popularization and application.
Especially in high-powered LED lamp, input power only 15%～20% electric energy be converted into luminous energy output, remaining is then changed
Become heat energy, if these heats fail to discharge the external world in good time, the luminous efficiency of light fixture not only can be made to reduce, and LED may be caused
Chip lost efficacy rapidly because temperature is too high and even damaged.
Utility model content
The purpose of this utility model is the shortcoming in order to overcome prior art to exist, it is provided that a kind of simple in construction, user
Just, good heat dissipation effect, be conducive to extending a kind of convection heat emission type bulb lamp of light fixture operation instruction.
This utility model purpose realizes with the following methods: a kind of convection heat emission type bulb lamp, it includes lamp holder and lamp
Cover, is connected by radiator between lamp holder with lampshade, is provided with heat conducting disk and LED light source is being arranged on it just in described radiator
Face, described heat conducting disk center is provided with interior convection holes and is connected with the outer convection holes being located at lampshade center, described
Spreader surface is provided with some convective tank, inside and outside convective tank conducting radiator so that air can flow in light fixture.
Described convective tank is the groove that radiator body material is inwardly stamped and formed out.
The inclined shape of described convective tank is arranged on the surface of radiator, and some guiding gutter uniform arrays are distributed.
Described radiator top is additionally provided with top convection holes.
The beneficial effects of the utility model are: 1, simple in construction, and production cost is low, improve the market competitiveness.2, utilization sets
Put convective tank on a heat sink and form, with the convection holes being arranged in lampshade and heat conducting disk, the path that air circulates so that air
Can flow inside and outside light fixture, make radiator and heat conducting disk carry out heat exchange, increasing heat radiation area with air simultaneously, thus ensure that
The radiating effect of this light fixture.3, new radiator and lampshade design novel appearance fashion, can fully promote the desire to purchase of user.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is made concrete further instruction.A kind of convection heat emission type bulb lamp, its bag
Include lamp holder 1 and lampshade 2, be connected by radiator 3 between lamp holder 1 with lampshade 2, be provided with heat conducting disk 4 in described radiator 3 and incite somebody to action
LED light source is arranged on its front, and described heat conducting disk 4 center is provided with interior convection holes 41 and is located at lampshade 2 center
Outer convection holes 21 connect, described radiator 3 surface configuration has some convective tank 31, and convective tank 31 turns on inside and outside radiator 3,
Air can be flowed in light fixture.
Described convective tank 31 is the groove that radiator 3 bulk material is inwardly stamped and formed out.
The described inclined shape of convective tank 31 is arranged on the surface of radiator 3, and some guiding gutter 31 uniform arrays are distributed.
Described radiator 3 top is additionally provided with top convection holes 32.
Operation principle: during actual use, the heat that LED light source produces is delivered to radiator by heat conducting disk
On, the surface of radiator and air carry out heat exchange, serve thermolysis when working light fixture.Wherein, in order to further
Strengthen light fixture heat-sinking capability, this case is provided with interior convection holes 41 in heat conducting disk 4 center and is located at lampshade 2 centre bit
The outer convection holes 21 put connects, and has some convective tank 31 in radiator 3 surface configuration, and convective tank 31 turns on inside and outside radiator 3.
Owing to when light fixture uses, the temperature of itself is relatively higher than ambient temperature, cause the air being positioned at lamp interior to be heated, cause
The density contrast of air and produce air flowing.The single surface with radiator of the flowing of air carries out heat exchange, also can be directly with scattered
The inner surface of hot device, heat conducting disk, lampshade surfaces externally and internally, even direct and LED light source carries out heat exchange, dissipates merely with traditional
Structure and the technology of hot device surface radiating are compared, and the structure in this case has bigger area of dissipation, thus also possesses and have more
Excellent heat dispersion, therefore can be widely popularized and be used in the use of various high-power LED lamp.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Having various changes and modifications, such as the form of radiating groove, the structure of convection holes and arrange position etc., these changes and improvements all fall
In the range of entering claimed this utility model.
