Description
Technical field
The utility model relates to field of semiconductor illumination, particularly a kind of LED bulb lamp of omnirange bright dipping.
Background technology
The large multiplex blue-light LED chip of the white light LEDs of prior art and fluorescent material form, and its principle is that the blue-light excited fluorescent material that LED chip sends produces gold-tinted, after blue light and yellow light mix, produces white light.Its encapsulation normally is fixed on LED chip on substrate with crystal-bonding adhesive, then cover phosphor powder layer on LED chip, yet, the LED light source of encapsulation is because the substrate used is transparent materials in this way, its lighting angle maximum only has 180 °, this packaged type has following several shortcoming: 1. because LED chip is 360 ° of illuminators originally, adopt opaque substrate to be connected for optically focused or with metal heat sink, usually in the bottom surface of LED chip, reflecting layer is arranged, so the illuminator that script is 360 ° is made into the illuminator of 180 °, this just makes the light of 180 ° of directive radiator one side will pass through the outgoing of reflection ability, therefore the reflectivity of substrate surface is very large on the impact of light efficiency, usually on substrate, make the argentum reflecting layer of high reflectance, somewhat expensive and making are complicated, cause bulb lamp with high costs, yield rate is lower.2 substrates cause obstruction to the heat radiation of LED chip, make the radiating effect of integrated light source bad, while utilizing this light source to make light fixture, generally all will consider supporting radiator, have both limited the structural design of light fixture, improve again the manufacturing cost of light fixture.3, for better heat radiation, substrate material generally adopts metal substrate, and the dielectric voltage withstand characteristic of metal substrate is poor, therefore needs to adopt the good die bond primer of insulating properties, but the transmitance of the die bond primer of good insulation preformance is lower, therefore further affected the light efficiency of whole system.
To this, a lot of producers consider to adopt transparency carrier to encapsulate bulb lamp, Chinese patent 200510089384.X for example, and it is placed in transmission substance to single led chip hanging shape, makes 360 ° of chips luminous; But it does not solve the heat dissipation problem of chip, chip does not have the electric lead-out wire reliability on the unsettled placement of gripper shoe, chip very poor.Also just like patent 201120319651.9,201220184752.4,201010278760.0 and 201010610092.7 etc., the LED light source of this class lamp is made with the LED light-emitting section of discrete transparency carrier encapsulation, the LED light-emitting section vertically is fixed in bulb by connector, this bulb is connected because substrate and power shelf adopt stem stem, therefore by stem stem, blocked can't transmission for some light, and the solder joint of this bulb assembling electric welding is many, and light-emitting section only connects by connector, the less heat dispersion that affects system of the contact area of connector.In sum, the LED lamp ubiquity light efficiency of the wide-angle bright dipping of prior art is not high, and reliability of electrical connection is poor, the assembling flow path complexity, and the bad shortcomings that waits dispels the heat.
