LED bracket, LED lamp beads in the package before the base, in the LED bracket on the basis of the chip will be fixed into the welding of positive and negative electrodes, and then a package of plastic packaging forming.
Led bracket is generally made of copper (also iron, aluminum and ceramics, etc.), because the copper conductivity is very good, it will be inside the lead, to connect the internal led lamp beads, LED lamp beads after forming, the lamp Beads can be removed from the bracket, lamp beads at both ends of the copper feet become the lamp beads of the positive and negative, for welding to LED lamps or other LED products.
LED bracket type and specification editor
LED bracket generally has a straight LED bracket, piranha LED bracket, patch LED bracket and high power LED bracket:
And straight line is generally used with the most, of which there are 02 short legs, 03 big angle red and yellow, 04LD do blue and white green, there are A5, A6 white, A7, A8 big cup at the end of 06 , 09 do two-color three-color and so on;
LED bracket size size of the luminous intensity or light angle has a certain impact, the heat of the LED optical properties and service life has a very direct relationship.
LED patch stent market SIDE VIEW 335 008 020 010, HIGH POWER TO220 LUXEON 1-7W, etc., because the specifications are not unified, so there are many special specifications.
Classification of LED brackets
1. According to the principle is divided into two kinds: condenser type (with cup bracket) and large angle astigmatism type Lamp (flat head bracket). For example: A, 2002 cup / flat head: This bracket is generally done on the angle, the requirements are not very high material, the pin length shorter than the other stent about 10mm. Pin spacing is 2.28mm. B, 2003 cup / flat head: generally used to do φ5 above the Lamp, exposed pin length for & nbsp; & nbsp; + 29mm, -27mm. Pin spacing is 2.54mm. C, 2004 cup / flat head: used to do φ3 around the Lamp. Pin length and spacing with the 2003 stent. D, used to do blue, white, pure green, purple Lamp, can be welded two lines, the cup deeper. E, 2006: poles are flat head type, used to do flashing Lamp, solid IC, welding a number of lines. F: 2009: used to make two-color Lamp, cup can be solid two, three pin control polarity. G: 2009-8 / 3009: used to do three-color Lamp, cup can be solid three chips, four pin feet. H: 724-B / 724-C: Stent used to make piranha.
