Abstract
The invention relates to the technical field of LEDs, in particular to an LED lamp with the two ends of a light source module tensioned and fixed. The LED lamp comprises the light source module and a shell arranged outside the light source module in a sleeved mode. A pre-tightening device for fixing the light source module is further arranged on the shell and fixedly connected with the two ends of the light source module in the length direction and applies tensioning pre-tightening force to the light source module in the length direction. The light source module is fixed due to the arrangement of the pre-tightening device, certain pre-tightening force is further provided while the light source module is fixed, and the light source module is not prone to bending after being tensioned and fixed; particularly, in the working state of the LED lamp, even though the temperature of the light source module rises and the light source module stretches to be a little longer, the elongation of the light source module can be counteracted instantly because of the pre-tightening force, and the light source module is still tensioned, so the light source module is still not prone to bending, and the quality of the product is directly improved.
Description
Technical field
The present invention relates to LED technical field, be specifically related to a kind of LED lamp of two ends tensioning fixed light source module.
Background technology
Current LED lamp generally include strip light source module, be set in the sheath body of light source module outside, and these several parts of supply module that are arranged on sheath body two ends form, for light source module is fixed in sheath body, current common way is the support that supporting light sources module is set at the two ends of sheath body.
There is following problems in the LED lamp of said structure, current light source module normally adopts PCB(printed circuit board) light source module or COMMB-LED light source module, because its rigidity own is not high, in the time that light source module is long, unsettled section of its middle part easily produces larger amount of bow, so be only inadequate at two end supports light source module, particularly in the time that LED lamp is worked, on light source module, temperature raises, the rigidity of light source module itself further reduces, further strengthen the degree of crook of light source board, directly affected product quality.
In order to solve this technical problem, current common way is as Chinese invention patent, " Straight LED lamp ", application number is: CN201210057918.0, that mentions directly sticks on tube inner wall by adhesion agent by LED light emitting module, this mode, the described support problem having solved LED light emitting module, but cause again other defect: because the intensity of adhesion agent own is not high, and the thermal coefficient of expansion of LED light emitting module and the thermal coefficient of expansion of fluorescent tube are inconsistent, so in start and stop repeatedly of LED light emitting module (i.e. repeatedly heated and turn cold) afterwards, adhesion agent between LED light emitting module and tube inner wall is easily by drawing crack, make the connection reliability variation between LED light emitting module and fluorescent tube, on the other hand, owing to being provided with one deck adhesion agent between LED light emitting module and fluorescent tube, make again the remarkable variation of heat dispersion of LED light emitting module, also directly affected the quality of product.
So needing at present one badly can excellent support light source module, simple in structure, makes again light source board have the LED lamp of excellent heat dispersion performance.
Summary of the invention
The object of the invention is to: in current LED lamp, light source module support above shortcomings, provide the one can excellent support light source board, and simple in structure, and make light source board have the LED lamp of excellent heat dispersion performance.
To achieve these goals, the technical solution used in the present invention is:
A kind of LED lamp of two ends tensioning fixed light source module, comprise light source module, be set in the sheath body of described light source module outside, on described sheath body, be also provided with the pre-tightening apparatus of fixing described light source module, described pre-tightening apparatus is fixedly connected with the both ends of described light source die group length direction, and imposes along its length stretch-draw pretightning force.By being set, pre-tightening apparatus fixes light source module, in playing fixed light source module, certain pretightning force is also provided, make to be difficult for bending after light source module is being strained and fixed, particularly under LED lamp duty, even if light source module temperature raises, length is extended slightly, due to the existence of pretightning force, the elongation of counteracting light source module that can be instant, and still strain light source module, thus make light source module still be difficult for bending, and then directly improved the quality of product; Meanwhile, due to other bracing or strutting arrangement or adhesion agent not being set between light source module and sheath body, thus make LED lamp have good light emission rate, and make light source module there is good heat dispersion, also ensure the quality of product.
