Description
Technical field
The utility model relates to the technical field of lighting, especially a kind of easy heat radiating LED lamp of good heat dispersion performance.
Background technology
LED light fixture has that luminous efficiency is high, power saving and long feature of life-span, and therefore its application is more and more extensive.Because LED lamp is when luminous, the temperature of himself can constantly raise, and in lasting illumination work, if the heat that LED lamp produces can not exhale in time, will cause the damage of LED lamp, so the heat dissipation problem of LED lamp is the emphasis that the industry is paid close attention to always.
The radiator structure major part of existing LED lamp is in lamp, to add fin; when this radiator structure is generally, the circulation of fin and air is dispelled the heat; belong to passive heat radiation; often there will be heat radiation phenomenon not in time; if continue to increase the quantity of fin; can cause the weight of LED lamp to become heavy, volume increases, and is not easy to librarian use.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of easily heat radiating LED lamp is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of easily heat radiating LED lamp, comprise upper cover, lower cover, light source and diffusion shell, one end of lower cover is connected with upper cover, the other end is connected with diffusion shell, light source is arranged on the bottom of lower cover and is positioned at lower cover and the cavity of diffusion shell formation, in the cavity of upper cover and lower cover formation, be disposed with power supply from top to bottom, power shelf, fan, heat radiation module and the substrate that is connected light source, described power supply is arranged on power shelf, heat radiation module is made up of several fin, several fin are around fan setting, lower cover is fixedly connected with bolt by connecting rod with power shelf, upper cover and power shelf are bolted to connection.
One end of described fin is arranged on substrate, and its other end is divergent shape and forms groove along the inwall of lower cover, and fan is positioned at groove.
The top of described upper cover is provided with screwed socket.
Described diffusion shell is transparent diffusion PC cover.
The beneficial effects of the utility model are: the utility model is easy to operate, increase fan, make radiating mode become active heat removal, accelerate the radiating rate of LED lamp, improve operating efficiency, be applicable to the LED lamp of different capacity, small volume, heat dispersion is stable, and the diffusivity of illumination is simultaneously improved.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
