Description of the Invention: [Technical Field] The present invention relates to a light source fixing member, and more particularly to a backlight module having the foregoing light source fixing member. [Prior Art] For the known direct-lit type optical module, a light emitting diode (LED) light bar is usually fixed on the back plate by screw fixing, and a LED lens cap is used. To reduce the thickness of the module and the number of light-emitting diodes. The light-emitting diode lens is fixed directly above the light-emitting diode by being adhered to a double-sided tape. However, taking a 4-inch LCD TV backlight module as an example, 22 LED strips are usually required, and at least 3 screws are required for each LED strip to assemble all the LEDs. A total of 66 screws are required for the body light bar, and the electric screwdriver is used to repeatedly suck and lock the screw up to 66 times, so the assembly process is rather cumbersome and time-consuming. In addition, when the double-sided adhesive is used to fix the light-emitting diode lens, since there is no positioning reference when pasting, it is easy to cause poor positioning and thus affect the optical performance, and the light-emitting diode is torn off once the re-work is required. The lens is usually easily damaged. Other conventional technologies, such as Taiwan Patent Publication TWM3713〇8, disclose a light-emitting diode module in which a light-emitting diode of a light-emitting diode module is disposed on a circuit board, and a secondary lens is used to cover the light-emitting diode. The joint portion of the secondary lens and the fixing portion of the circuit board are connected to 201224341 by bonding, snapping, locking or fitting. In addition, U.S. Patent No. 2,060,279,946 discloses a backlight module such that the backlight module has a --clamped light source. However, these prior art techniques do not address designs that address the aforementioned problems encountered in assembly.

The light-emitting one-pole lens is embedded in the first fastening structure to be fixed to the light source fixing member. In one embodiment, the 'first-clamping structure' includes a plurality of hooks 201224341 distributed in different orientations. Some of the hooks are distributed, for example, on the sm of the same-virtual circular lang-virtual outline and the illuminating diode lens has an outer contour corresponding to a virtual circular or a virtual ellipse. In one embodiment, the second fastening structure includes at least one hook, for example, two hooks disposed opposite to each other. In the case of the Belle®, the light-emitting one-pole light bar is formed with at least one through hole, and the through-hole forming position coincides with the card hole of the back plate.

The base has opposite - first faces and - second faces, the second face faces the back plate and the back plate is formed with at least one card hole. The first fastening structure is formed on the first surface and defines a card slot, and the card slot is embedded in a light emitting diode lens. The second fastening structure is formed on the first surface, the second fastening structure is embedded in the hole of the back plate to fix the light source fixing member on the back plate, and a light-emitting diode light bar is limited to the back plate and the light source fixing member between. In summary, the light source fixing member and the backlight module of the embodiment of the present invention have at least one of the following advantages: By the design of the above embodiment, the light emitting diode is fixed by a light source fixing member including a hook structure, for example. The lens and the LED strip can be used to limit the LED strip to the back panel through a simple snap action. This can replace the traditional screw locking method to simplify the assembly process and process and save man-hours. And reduce the cost of manufacturing. In addition, the LED lens also uses the 201224341 card method instead of the conventional double-sided tape, which is not only easy to nibble, but also easy to remove the king, and can reduce the time and improve the assembly efficiency. . Other objects and advantages of the present invention can be further understood from the technical features disclosed in the present invention. The above and other objects, features and advantages of the present invention will become more apparent from [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly described below in conjunction with the detailed description of the relevant aspects.
