Aforementioned and other technology contents, feature and effect for the present invention, in the detailed description of following cooperation with reference to graphic embodiment, can clearly present.The direction term mentioned in following examples such as: upper and lower, left and right, front or rear etc., is only the direction with reference to annexed drawings.Therefore, the direction term of use is used to illustrate and is not used for limiting the present invention.
Fig. 1 is the partial cutaway schematic view of the light source assembly according to one embodiment of the invention.As shown in Figure 1, light source assembly 10 comprises backboard 12, light-emitting diode light bar 14, positioning piece 16 and a posting 18.In the present embodiment, backboard 12 comprises a base portion 12a and connects a sidepiece 12b of base portion 12a, and sidepiece 12b and base portion 12a presss from both sides an angle.Light-emitting diode light bar 14 to be arranged on backboard 12 and to have multiple light emitting diode 14a.Please also refer to Fig. 2 A and Fig. 2 B, in the present embodiment, the base portion 12a of backboard 12 forms at least certain hole, position 22,1 first snap fit 24 and one second snap fit 26.First snap fit 24 and the second snap fit 26 have a spacing and both the almost parallel Y direction of a line each other, and the length of light-emitting diode light bar 14 on a long axis direction (long axis direction of light-emitting diode light bar is shown as Y direction in Fig. 2 A, Fig. 2 B) can be substantially equal to the spacing between the first snap fit 24 and the second snap fit 26.When light-emitting diode light bar 14 is arranged between the first snap fit 24 and the second snap fit 26, the two ends of light-emitting diode light bar 14 can be spacing between the first snap fit 24 and the second snap fit 26 against the first snap fit 24 and the second snap fit 26 respectively, to obtain light-emitting diode light bar 14 locating effect in the Y-axis direction.Refer again to Fig. 1, keeper 16 has one first side P of adjacent light-emitting diode light bar 14 and one second side Q of adjacent backboard 12, and the second side Q forms at least certain position post 28, locating dowel 28 can embed the locating hole 22 of backboard 12, makes the first side P of keeper 16 against light-emitting diode light bar 14.Light-emitting diode light bar 14 like this both sides in the X-axis direction can, respectively against the first side P of backboard sidepiece 12b and keeper 16, to obtain locating effect in the X-axis direction, and can make the second side Q of keeper 16 against backboard base portion 12a.In the present embodiment, light-emitting diode light bar 14 forms one first end difference 14b, first side P of keeper 16 forms the one second end difference 16b with the first end difference 14b complementary configuration, therefore when locating dowel 28 embeds the locating hole 22 of backboard 12, second end difference 16b against the first end difference 14b, can obtain light-emitting diode light bar 14 locating effect in the Z-axis direction.Profile and the material of keeper 16 do not limit, such as, can be an adhesive tape, and a reflection glue 38 can be arranged on one of keeper 16 on the surface to improve light utilization efficiency.Posting 18 can have one first barricade 18b and the one second barricade 18c of a base portion 18a and vertical base 18a, first barricade 18b and the second barricade 18c can define a draw-in groove 18d, and the height of the second barricade 18c relative positioning frame base portion 18a such as can be less than the height of the first barricade 18b relative positioning frame base portion 18a.When after assembling posting 18, backboard sidepiece 12b can spacing in draw-in groove 18d and one end of the second barricade 18c can against the base portion of the backboard dorsad 12a of light-emitting diode light bar 14 one surface, the locating effect of light-emitting diode light bar 14 in Z-direction can be obtained equally.Moreover reflection glue 38 can be arranged on one of posting 18 on the surface to improve light utilization efficiency.
As shown in Figure 3, in one embodiment, locating hole 22 such as can comprise a first area 22a and a second area 22b of tool different pore size, and the aperture of first area 22a is greater than the aperture of second area 22b.Therefore, locating dowel 28 can penetrate wide-aperture first area 22a easily, then pushes away the second area 22b embedding small-bore forward, and the chimeric action between locating dowel 28 and locating hole 22 so can be made more smooth-going.In addition, one snap fastener may correspond to and is formed on backboard 12 and posting 18, for example, as shown in Figure 4, the both sides of posting 18 can form a trip 18e respectively, and the corresponding trip 18e position of backboard 12 can form a draw-in groove 12c respectively, and snap fastener comprises the trip 18e of the posting 18 and draw-in groove 12c of backboard 12, when trip 18e embeds draw-in groove 12c, posting 18 can be fixed on backboard 12.
Fig. 5 is the partial cutaway schematic view of the light source assembly according to another embodiment of the present invention.As shown in Figure 5, in light source assembly 40, light-emitting diode light bar 14 and keeper 16 do not form corresponding end difference, but against light-emitting diode light bar 14, therefore can obtain light-emitting diode light bar 14 locating effect in the Z-axis direction equally because of one end of the second barricade 18c of posting 18.In addition, the extensible formation one in the side projection 18f of posting 18 against keeper 16, to limit the movement of keeper 16 in X-direction, obtain light-emitting diode light bar 14 locating effect in the X-axis direction.Moreover the side of keeper 16 also can form coupler construction 42 as shown in Figure 6, to guarantee further can not move in the X-axis direction against the keeper 16 after light-emitting diode light bar 14.Moreover, as shown in Figure 7, backboard 12 is except forming the first snap fit 24 and the second snap fit 26 to limit except light-emitting diode light bar 14 movement in the Y-axis direction, also can be formed in addition on line that one the 3rd snap fit the 44, three snap fit 44 is not arranged on the first snap fit 24 and one second snap fit 26 therefore light-emitting diode light bar 14 movement in the X-axis direction can be limited.Keeper 16 can be omitted by above-mentioned design, only need recycling posting 18 to limit light-emitting diode light bar 14 movement in the Z-axis direction, light-emitting diode light bar 14 can be allowed to be fixed on backboard 12.
In sum, the light source assembly of embodiments of the invention at least has one of them advantage following:
By the design of above-described embodiment, because light-emitting diode light bar is fixed on backboard by keeper, posting or the limit effect that is formed in the snap-in structure on backboard and provides, the bonding method using fixing glue or double faced adhesive tape can not be needed like this, avoid producing as existing design, light-emitting diode light bar, easily because of the phenomenon producing local detachment with backboard of being heated, improves product reliability and reliability.In addition, light-emitting diode light bar utilize engaging and against limit method, the operation of disassembling or replacing light-emitting diode light bar can be made to become easy, and avoid light-emitting diode light bar assembling or unloading process in distortion or damage.
The above, be only preferred embodiment of the present invention, can not limit scope of the invention process with this, and the simple equivalence namely generally done according to the claims in the present invention and invention description content changes and modifies, and all still remains within the scope of the patent.In addition, any embodiment of the present invention or claim must not reach whole object disclosed by the present invention or advantage or feature.In addition, the term such as " first ", " second " of mentioning in this description or claim only in order to name the title of element (element) or to distinguish different embodiment or scope, and is not used for the quantitative upper limit of limiting element or lower limit.
