Description
Technical field
The utility model relates to the technical field of LED accessory, specifically a kind of fixture for fixed L ED lamp source structure and light source drive.
Background technology
Efficiently, energy-conservation, the LED lamp of environmental protection is the trend of Future Consumption.LED lamp generally comprises chassis, diffuser, LED light source structure, and light source drive.Wherein LED light source structure comprises circuit board, is located at the lamp pearl on circuit board.In existing technology, LED light source structure, and light source drive is generally installed by following three kinds of modes and is fixed on chassis, analyzes its pros and cons one by one below.
The first: on chassis and light-source structure and light source drive, offer some installing holes accordingly, by screw will, LED light source structure, and light source drive is spirally connected and is fixed on chassis.Tradition is simple the most for this kind of version.Shortcoming: consumer maintain change time not easily.Reason is the ununified dimensional standard of the mounting hole site on LED light source structure and light source drive and chassis on market, causes consumer maintaining difficulty when changing.The LED that major part is sold on the market on the other hand has dress fin except unspecific purposes, is generally utilize chassis to work as fin usually.When being screwed on chassis, cannot suitably displacement when expanding with heat and contract with cold, in use for some time, produce the impact of luminous energy by the luminescence of lamp pearl, LED light source structure overall structure temperature raises usual LED light source structure.After the structural circuit board expanded by heating of LED light source cannot free-extension because to be fixed on chassis, will torsional deformation be produced, and cannot be smooth be attached on chassis, dispel the heat via chassis.And lamp pearl when being elevated to certain temperature on circuit board will easily damage, affect the light-struck uniformity of LED, and then shorten the service life of LED.
The second: LED light source structure is screwed on a magnetic receiver, then be fixed on chassis by magnet adsorption, consumer is easy when maintaining replacing.Shortcoming: this structure is only conducted heat by magnetic receiver and to be dispelled the heat to chassis, the lamp pearl of LED, and the heat that Long-Time Service produces, cannot obtain effective distribute heat.Be easy to cause the lamp pearl of LED to damage, affect the life-span of LED.
The third: be arranged on by magnet in LED light source structure, such structure installment is easy, good heat dissipation.Shortcoming: make complicated, large-scale production has certain difficulty, so the height that cost is relative.On the other hand this product is commercially sold single, when consumer buys LED, cannot the LED of more each manufacturer, therefore the selection of consumer is very limited.
In sum, how realizing that a kind of cost is low, structure is simple, installing/dismounting is simple and efficient, good heat dissipation effect and be applicable to the fixture of all LED light source structures and light source drive on market, is technical problem anxious to be resolved in the industry.
Summary of the invention
The purpose of this utility model is to provide a kind of fixture for fixed L ED lamp source structure and light source drive of improvement, it can overcome, and fixture structure in prior art is complicated, installing/dismounting not easily, the some shortcomings of radiating effect difference.
To achieve these goals, the technical solution of the utility model is: a kind of fixture for fixed L ED lamp source structure and light source drive, it mainly comprises chassis, it is characterized in that: chassis is provided with light source drive device and light-source structure from inside to outside successively, light-source structure upper surface is equipped with circuit board, directly fit in bottom surface and the chassis of light-source structure, above-mentioned light source drive device, light-source structure are fixedly connected with chassis by fixture, and described fixture is formed by connecting by handle and the magnetic absorption part be located at bottom handle.
During use, by fixture, light source drive device and light-source structure are fixed with on chassis, fixture is formed by connecting by handle and magnetic absorption part, Magnetic absorbing element is fixed on chassis, a gap is formed between the bottom of handle and chassis, size due to handle is greater than the size of magnetic absorption part, light source drive device and light-source structure are just in time arranged on chassis by therefore described gap, make the bottom of light-source structure and chassis fit tightly simultaneously, reach good radiating effect, simultaneously fixture due to structure simple, easy installation and removal, cost is low, be easy to promote and use.
