Fig. 2 is the structural representation of lens module of the present utility model.As shown in Fig. 2 (a), the buckle peace of lens module 2 Dress hole is common circular port 22, shown in Fig. 2 (b), and the buckle mounting hole of lens module 2 is square opening 23, in lens module 2 There are two positioning boss 21 (positioning boss that side is only shown in figure) both sides.

Fig. 3 is the schematic diagram of buckle-type lens installation structure of the present utility model.In Fig. 3, small figure is buckle part Amplification profile.Fig. 3 (I)-Fig. 3 (III) is the schematic diagram of the buckle-type lens installation structure of the utility model embodiment 1~3.

Specific embodiment 1

As shown in Fig. 3 (I), LED lens modularity buckled mounting structures, from bottom to up including PCB 1, thoroughly Mirror module 2 and buckle 3, PCB 1 are provided with the positioning hole 11 corresponding with the positioning boss 21 of lens module 2, when When the positioning boss 21 of lens module 2 is caught in the positioning hole 11 of PCB 1, lens module 2 is relative to PCB circuit boards 1 There is the free degree (above-below direction) in a direction, the movement in this direction can be by being affixed on PCB together in lamp bead paster 1 buckle 3 (31,32,33) is fixed.

Buckle 31 is nickel plating stainless steel, chip mounter can be used to be affixed on PCB 1 in LED lamp bead paster together Buckle install pad 12 position on.When LED lamp is assembled, PCB 1 is fixed on lamp outer casing first, connect Only need to by the positioning boss 21 and central circular hole (i.e. buckle fixing hole) 22 of lens module 2 respectively with PCB 1 The center alignment of positioning hole 11 and the buckle 31 being affixed in PCB, is gently pressed, and lens module 2 can be caught in PCB Circuit board 1 and buckle 31, all directions are fixed.

Obviously, the present embodiment is simple to operate, and packaging efficiency is high.In actual applications, PCB 1 can be according to other The positioning boss of different lens modules opens up corresponding positioning hole and buckle 31 is affixed on into corresponding pad locations；For not having Have for the lens module of positioning boss, snaps into position hole can be corresponded to respective numbers are pasted on the relevant position of PCB 1 Buckle a.The lens module in Fig. 3 (I) is not limited in practical application, the various demands that meet can be expanded in many ways Lens module, such as 3 × 3 lens modules, 3 × 4 lens modules etc..

Specific embodiment 2：

Buckle used in Fig. 3 (II) is buckle 32, and buckle 32 is all nickel plating stainless steel, using panel beating Form, cost is relatively low.It is similar to Example 1 in specific implementation, when PCB 1 carries out lamp bead paster, by buckle 32 The buckle of PCB 1 is together affixed on to install on the position of pad 12.Then when LED lamp is assembled, first by PCB circuits Plate 1 is fixed on lamp outer casing, then only need to by the positioning boss 21 of lens module 2 and middle buckle fixing hole 23 respectively with The positioning hole 11 of PCB 1 and the center alignment of buckle 32, are gently pressed, and lens module 2 can be caught in the He of PCB 1 Buckle 32, all directions are fixed.

The present embodiment snaps into position hole be square hole when, i.e., buckle mounting hole 23 when, effect is best.It is in buckle mounting hole Circular hole can equally realize buckle comprehensive fixation when being the pattern of buckle mounting hole 22, contact surface is mainly the U-shaped of buckle 32 The four edges of piece, in order to obtain more contacts area, can process in the arc-shaped by buckle 32.

Embodiment 3

Buckle used in Fig. 3 (III) is buckle 33, and buckle 33 is ageing-resistant high-temperature resistant rubber material.PCB circuits Plate 1 ' is different from PCB 1 in first two embodiment, and the hole corresponding with buckle 33 of PCB 1 ' is to have certain taper Bellmouth 13, in brief, the aperture of the one side that PCB 1 ' is contacted with lamp housing is more than the aperture of another side.

In the whole lamp installation processes of LED, first by the positioning hole of the correspondence PCB 1 ' of positioning boss 21 of lens module 2 11 are caught in PCB 1 ', then penetrate the one side big from aperture of buckle 33 in lens module 2, because rubber has necessarily Elasticity, the top of buckle 33 is by being extruded through the buckle mounting hole 22 of lens module 2, afterwards to shape back to normal, card Detain 33 bottoms consistent with the shape of the bellmouth 13 of PCB 1 ', such buckle 33 is just by PCB 1 ' and lens mould Group 2 is securely fixed together, and finally PCB 1 is fixed on lamp outer casing again.

Likewise, the present embodiment is not limited to parts shown in Fig. 3 (III), such as lens can select other a variety of Modularity lens；Buckle 33 also may be selected top in metal material, profile and can be replaced, bottom and buckle similar to buckle 31 33 is similar.In a word, can multi-faceted extension extension herein on basis.

Technology contents and technical characterstic of the present utility model are had revealed that as above, but those skilled in the art still may be used A variety of replacements and modification without departing substantially from the utility model spirit can be made based on teaching of the present utility model and announcement.Therefore, originally The protection domain of utility model should be not limited to the content disclosed in embodiment, and should be replaced including various without departing substantially from of the present utility model Change and modify, and covered by present patent application claims.
