The utility model content
Therefore, the utility model proposes a kind of package assembly simpler, the monomer infrared LED lens arrangement that 50% light intensity angle is less.
The technical solution of the utility model is:
Monomer infrared LED lens arrangement comprises:
One outer casing member, this outer casing member are a cylinder-shaped structure, and cylinder body bottom offers one and is used for LED lamp pearl is inserted in fixing hollow out opening, and cylinder inboard wall is provided with at least 2 grafting rail grooves;
One lens piece, this lens piece structure that is formed in one, it is an inverted Rotary-table, frustum cone side is provided with at least 2 grafting columns, be plugged in by the grafting column outer casing member cylinder inboard wall the grafting rail groove and lens piece is fixed in the outer casing member, the centre of large round table surface is to lower recess, the bottom surface of depression forms convex surface on the lens, the centre of little round table surface is to lower recess, and the bottom surface of depression forms the lower convex surface of lens;
One spacer elements, this spacer elements are slim disk, and the centre of disk is provided with the hollow out opening consistent with the cylinder body bottom size shape of outer casing member, and this spacer elements is glued on the cylinder body bottom outer surface of outer casing member.
Further, the large round table surface lower end of described lens piece is provided with a projection along being provided with a breach for the nozzle of described outer casing member interior, pegs graft at described lens piece and is fixed in the outer casing member, and then the projection of lens piece is sticked in the breach of outer casing member just.
Further, the quantity of the grafting column on the grafting rail groove on the cylinder inboard wall of described outer casing member and the frustum cone side of described lens piece is 4, is symmetric on circumference.
The optimal design of monomer infrared LED lens arrangement scioptics spare shape of the present utility model can reach 6 ° 50% light intensity angle, and optical convergence's effect is very good.Simultaneously, this monomer infrared LED lens arrangement only needs lens piece to be fixed in the outer casing member by the mode of pegging graft, and the lower recess of the little round table surface of the hollow out opening by outer casing member and lens piece forms the space and is inserted in LED lamp pearl fixing.Therefore, this monomer infrared LED lens arrangement is very simple, is easy to assembling.

The specific embodiment
Now with the specific embodiment the utility model is further specified by reference to the accompanying drawings.
Consult Fig. 1-shown in Figure 6, the monomer infrared LED lens arrangement of embodiment comprises:
One outer casing member 1, this outer casing member 1 is a cylinder-shaped structure, and cylinder body bottom offers one and is used for LED lamp pearl is inserted in fixing hollow out opening 12, and cylinder inboard wall is provided with 11,4 grafting rail grooves 11 of 4 grafting rail grooves and is symmetric on circumference; Also can be 2, more than 3 or 4.The lighttight working of plastics of outer casing member 1 general employing is made.
One lens piece 3, this lens piece 3 structure that is formed in one, it is an inverted Rotary-table, frustum cone side is provided with 4 grafting columns 31 that are symmetrically distributed in circumference, be plugged in by grafting column 31 outer casing member 1 cylinder inboard wall grafting rail groove 11 and lens piece 3 is fixed in the outer casing member 1, the centre of large round table surface 301 is to lower recess, the bottom surface of upper sinking space 33 forms convex surface 303 on the lens, the centre of roundlet table top 302 is to lower recess, and the bottom surface in lower recess space 34 forms the lower convex surface 304 of lens.The lens piece 3 general light-transmissive resin materials that adopt are made, such as acrylic or PC etc.Because the acting in conjunction of the lower convex surface 304 of convex surface 303, lens can make the convergence of rays of the LED lamp pearl that is enclosed within lower recess space 34 on the frustum cone side of lens piece 3 and the lens, reaches 6 ° 50% light intensity angle.
