Description

High-power LED bracket

Technical field:

The invention belongs to the LED technical field, particularly a kind of high-power LED bracket.

Background technology:

The structure of led support and LED holder has been applied for multinomial patent before the applicant, is called the utility model patent of " high-power LED bracket " etc. for CN201327841Y, name such as Granted publication number.At present, other producers adopt direct stamping forming method for the processing of support and each supporting pins on applicant and the market, and then carry out mould-injection with the support after the punch forming and be processed to form the LED holder, this process technology is fit to the thinner situation of support on the one hand, if support is thicker, then when mould-injection, be difficult to make the LED holder to form the parcel effect; Simultaneously, the lens that the LED holder that adopts this technology to process mainly cooperates plastic cement, silica gel material to make, and the lens light transmission of plastic cement, silica gel material is bad; In addition, existing led support can not be crossed Reflow Soldering processing, produces inconvenience, therefore, is necessary very much prior art is improved.

Summary of the invention:

The object of the invention is to provides a kind of high-power LED bracket for the deficiencies in the prior art; This high-power LED bracket is fit to the thicker situation of support, and the hard to bear cooperation quartz lens of energy, improves light transmission, and this product can also be crossed Reflow Soldering processing.

For achieving the above object, the present invention adopts following technical scheme:

It comprises the sheet support, and support is gone into battle and shown a plurality of LED holders, has hollow-out parts on the support, and the LED fixed seating is in hollow-out parts, and support is extended with the supporting pins that supports the LED holder in hollow-out parts, and etching has recessed step on the supporting pins.

Support is gone into battle and is shown a plurality of single supports, and single support has hollow-out parts, and single support is extended with stake body to hollow-out parts, and stake body is connected with single support by supporting pins, and etching has recessed step on the supporting pins.

Stake body is wrapped with the plastic cement seat and forms the LED holder.

Have the die bond groove on the stake body at LED holder middle part, the zone that the die bond groove surrounds is crystal bonding area.

The local step of plastic cement seat parcel supporting pins can utilize this step to make the plastic cement parcel more stable.

Be extended with supporting pins to hollow-out parts respectively around the single support, be formed with the electrode pad of relative step projection on the supporting pins.

Electrode pad on the supporting pins has two groups, and identical electrical electrode pad connects by the arc connecting portion.

The etching of arc connecting portion has recessed step.

Beneficial effect of the present invention is, etching has recessed step on the supporting pins, on the one hand, can make the plastic cement seat of LED holder keep stable with stake body by this step be connected, on the other hand, be convenient to the cut-out of supporting pins, can also hard to bear cooperation quartz lens, improve light transmission, and this product can also be crossed Reflow Soldering processing.

Embodiment:

The present invention is further illustrated below in conjunction with accompanying drawing.

Shown in Fig. 1-8, the present invention includes sheet support 10, support 10 is gone into battle and is shown a plurality of LED holders 20, being convenient to like this mass gives birth to, has hollow-out parts on the support 10, LED holder 20 is positioned at hollow-out parts, and support 10 is extended with the supporting pins 41 that supports LED holder 20 in hollow-out parts, and etching has recessed step 50 on the supporting pins 41.

Support 10 is gone into battle and is shown a plurality of single supports 40, single support 40 has hollow-out parts, single support 40 is extended with stake body 42 to hollow-out parts, stake body 42 is connected with single support 40 by supporting pins 41, etching has recessed step 50 on the supporting pins 41, and the thickness of step 50 is half of stake body 42 and support 10 thickness.

Wherein, stake body 42 is wrapped with plastic cement seat 30 and forms LED holder 20.

Further, have die bond groove 43 on the stake body 42 at LED holder 20 middle parts, the zone that die bond groove 43 surrounds is crystal bonding area.

Wherein, the local step 50 of plastic cement seat 30 parcel supporting pins 41.

The characteristics of maximum of the present invention, namely be to adopt the method for chemical corrosion to etch recessed step 50 in supporting pins 41, if adopt the method for existing direct punching press then can't process this step 50, if and can't process step 50, then 30 of plastic cement seats can not stably be fixedly connected with stake body 42.

Be extended with supporting pins 41 to hollow-out parts respectively around the single support 40, be formed with the electrode pad of relative step 50 projections on the supporting pins 41.

Electrode pad on the supporting pins 41 has two groups, and identical electrical electrode pad connects by arc connecting portion 44, and adopting the connecting portion 44 of arc mainly is to cooperate with stake body 42, and fixing with plastic cement seat 30 to a greater extent.

44 etchings of arc connecting portion have recessed step 50, adopt the method for chemical corrosion to etch recessed step 50 at connecting portion 44, also are fixing with plastic cement seat 30 to the full extent, make plastic cement seat 30 keep stable.

Certainly, above-described embodiment is preferred embodiments of the present invention, is not to limit the scope of the present invention, therefore all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify, and all should be included in the present patent application claim.
