Abstract
The utility model discloses a lamp bead type high-power light-emitting diode (LED) light source which comprises a light source support main body, chips and a fixing cover, wherein a fixing seat is placed at the lower end of the light source support main body, a cross-shaped fixing column is placed at the upper end of the fixing seat, and bonding wire columns are placed at four corners of the fixing column. The chips are arranged on an upper end face and an outer side face of the light source support main body, electrodes are placed in the middle of the upper end face of the light source support main body, and the chips are connected on the electrodes through bonding wires in series. The fixing cover is placed on the fixing column, and the lower end of the fixing cover is fixedly installed on the fixing seat at the lower end of the light source support main body through a fixing ring. The lamp bead type high-power LED light source overcomes the defects of the prior art, and is simple in design and reasonable in structure. Heat of the chips is conducted away from a bottom disc. Due to the fact that the chips are fixed on five cube faces, 80% luminous flux can be reflected to space needing lighting through a reflector of a lamp, and string light can be greatly reduced.
Description
Technical field
The utility model relates to LED encapsulation technology field, specifically belongs to lamp pearl formula high-power LED light source.
Background technology
Existing high-power (more than 5 watts) led light source all is the COB integrated form on plane, its lighting angle is generally in 80-90 degree scope, the place that only adapts to directional lighting, the wide place that needs floodlighting is difficult to adapt to, or poor effect, simultaneously it also has two large major defects: the one, and it is too strong to dazzle light, diminishes human vision health; The 2nd, heat conduction is not smooth, directly affects the service life of led light source.
The utility model content
The purpose of this utility model has provided lamp pearl formula high-power LED light source, the deficiencies in the prior art have been overcome, simplicity of design, rational in infrastructure, chip heat is led away from bottom disc rapidly, because chip is fixed on five cubic planes, 80% luminous flux can be sent to through the reflector of light fixture needed lighting space, and string light can reduce greatly.
The technical solution adopted in the utility model is as follows:
Lamp pearl formula high-power LED light source, comprise light source bracket main body, chip and fixed cover, described light source bracket main body lower end has holder, the holder upper end has " ten " font fixed leg, four jiaos of fixed legs are provided with the bonding wire post, chip is arranged at light source bracket main body upper surface and lateral surface, and centre position, light source bracket main body upper surface is provided with electrode, and chip is connected in series on the electrode by bonding wire; Described fixed cover is arranged on the fixed leg, and the lower end is installed on the holder of light source bracket main body lower end by retainer plate.
Be provided with the PP insulating barrier between described electrode and the light source bracket main body.
To be that red copper is silver-plated make described light source bracket main body.
Be provided with insulating barrier between described light source bracket main body and the bonding wire post.
Described fixed cover is silica gel or resin bed.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, the light source bracket main body is that the silver-plated base of making of red copper is disc structure, and chip heat is led away from bottom disc rapidly, because chip is fixed on five cubic planes, 80% luminous flux can be sent to through the reflector of light fixture needed lighting space, and string light can reduce greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is inner plan structure schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, lamp pearl formula high-power LED light source comprises light source bracket main body 1, chip 2 and fixed cover 3, and fixed cover 3 contains silica gel or the resin bed of yellow phosphor powder.Light source bracket main body 1 lower end has holder 102, and the former rack body 1 of light is made for red copper is silver-plated.Holder 102 upper ends have " ten " font fixed leg 101,101 4 jiaos of fixed legs are provided with bonding wire post 4, chip 2 is arranged at light source bracket main body 1 upper surface and lateral surface, because chip 2 is fixed on five cubic planes, 80% luminous flux can be sent to through the reflector of light fixture needed lighting space, and string light can reduce greatly.Centre position, light source bracket main body 1 upper surface is provided with electrode 5, is provided with insulating barrier between light source bracket main body 1 and the bonding wire post 4.Be provided with PP insulating barrier 6 between electrode 5 and the light source bracket main body 1.Chip 2 is connected in series on the electrode 5 by bonding wire; Fixed cover 3 is arranged on the fixed leg 101, and the lower end is installed on the holder 102 of light source bracket main body 1 lower end by retainer plate 7.Fixed chip 2 on the light source bracket main body 1, can lead away chip 2 heats from bottom disc holder 102 rapidly.
