Abstract
The utility model discloses a built -in power supply heat sinking structure of desk lamp, technological purpose provides the built -in power supply heat sinking structure of desk lamp that a heat dispersion is good, realize two kinds of radiating modes of heat conduction and convection current through the base. Including lamp holder and lamp pole, the lamp pole is connected with the base, the base is including plastic housing, be equipped with drive power supply among the plastic housing, drive power supply connects the lamp holder and supplies power for the lamp holder, the drive power supply below is equipped with a heat conduction film, the heat -conducting metal piece of plastic housing below is located in the contact of heat -conducting glue piece. Article also must be joined in marriage as the counter weight of desk lamp simultaneously to this heat -conducting metal piece, and the heat dissipation that has embodied it again worth. The utility model discloses the radiating effect is good, has protected the electronic components in plastic housing and the desk lamp, is applicable to to use in the desk lamp.
Description
Technical field
The utility model relates to a kind of radiator structure, in particular, relates to the power supply heat sinking structure that a kind of desk lamp is built-in.
Background technology
In the prior art, desk lamp needs use driving power to realize power supply in use, driving power operationally can produce high heat, needs a good radiator structure to complete heat radiation, to reduce serviceability temperature, extend the service life of desk lamp and to prevent accident generation on fire.In use, desk lamp driving power produces heat can not produce heat radiation in the inner space closed, temperature will inevitably be caused constantly to rise and affect the physical property of the plastic shell of Desk lamp feet, plastic shell is generated heat be out of shape, even softening, also accelerated ageing simultaneously, and there is potential safety hazard on fire, overheated temperature on the impact of electronic devices and components also generation time, and causes built-in power to damage, and desk lamp produces fault.The many employings of radiator structure of desk lamp driving power of the prior art directly arrange aluminium base to dispel the heat on driving power, and this radiator structure also exists the high and technological deficiency of radiating effect difference of production cost; The technological deficiency of the radiator structure existence of current desk lamp, becomes the technical problem that those skilled in the art are anxious to be resolved.
Summary of the invention
Technical purpose of the present utility model overcomes desk lamp of the prior art heat radiation to there is the high and technical problem that radiating effect is general of production cost, provides a kind of excellent heat dissipation performance, realized the built-in power supply heat sinking structure of the desk lamp of heat conduction and convection current two kinds of radiating modes by base.
For realizing above technical purpose, the technical solution of the utility model is:
The power supply heat sinking structure that a kind of desk lamp is built-in, include lamp holder and lamppost, described lamppost is connected with base, it is characterized in that: described base includes plastic shell, driving power is provided with in described plastic shell, driving power connects lamp holder also for lamp holder is powered, and be provided with a heat conduction film below described driving power, described heat conduction film contact is located at the heat-conducting metal block below plastic shell.
Described heat conduction film is provided with lower through-hole.
Technique effect of the present utility model is: the heat solving inside by arranging heat conduction film outwards transmits, driving power thermal contact conductance film, heat-conducting metal block is transferred heat to by heat conduction film, the upper lower through-hole of heat conduction film plays certain heat loss through convection effect, this heat-conducting metal block also must join product as the counterweight of desk lamp simultaneously, and the heat radiation again embodying it is worth.After the balance that the internal and external temperature when base reaches certain, the temperature of built-in driving power no longer rises, and protects the electronic devices and components in plastic shell and desk lamp.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Composition graphs 1, in the power supply heat sinking structure that a kind of desk lamp of the utility model is built-in, include lamp holder 100 and lamppost 101, described lamppost 101 is connected with base, and base is for supporting lamp holder 100 and lamppost 101; Base includes plastic shell 102, driving power 103 is provided with in described plastic shell 102, driving power 103 connects lamp holder 100 also for lamp holder is powered, in concrete enforcement, a heat conduction film 104 is provided with below driving power 103, described heat conduction film 104 is provided with lower through-hole, and upper lower through-hole is used for cross-ventilation heat radiation.Described heat conduction film 104 contacts the heat-conducting metal block 105 be located at below plastic shell.This heat-conducting metal block 105 also must join product as the counterweight of desk lamp simultaneously, and the heat radiation again embodying it is worth.Described heat-conducting metal block 105 is provided with and holds heat conduction film 104, and in one embodiment, heat conduction film 104 is firmly closely attached on heat-conducting metal block 105; And heat conduction film 104 is provided with some fin.Heat-conducting metal block 105 is provided with latticed support slot 106.
The utility model transfers heat to heat-conducting metal block 105 by heat conduction film, heat-conducting metal block 105 can adopt aluminium alloy or copper material to make, the upper lower through-hole of heat conduction film 104 plays certain heat loss through convection effect, and radiating effect is splendid, is one, this area not only practicality but also novel technological improvement.
