Description
Technical field
The utility model relates to a kind of lighting apparatus field, particularly relates to a kind of LED bulb lamp.
Background technology
Along with improving constantly of LED technology; The LED illumination more and more receives people's attention, but compares with the traditional lighting apparatus, and the development of LED illumination also is faced with problems; Such as; At present LED receives technique influence mainly with the area source bright dipping, and the lighting angle of single LEDs is difficult to satisfy the requirement of traditional lighting full angle bright dipping generally about 120 degree.On the other hand, the LED caloric value is big, and heat radiation requires also very high to product.To above-mentioned defective, main solution mainly contains following several kinds at present:
1, planar light source LED increases fluorescent material through adding the large ball games bubble on the ball bubble, adds light diffusion material, breaks up the rising angle that improves product to light, realizes the full angle bright dipping.But the whole lamp size of traditional LED lamp is that certain restriction is arranged, and when the shared ratio of ball bubble was big, the ratio of heat radiation cup just must reduce, and heat-sinking capability also just and then descends.Though and the ball bubble adds fluorescent material and light diffusion material helps breaing up light, makes the light transmittance of ball bubble descend, diffusion effect is good more, and light transmittance is also poor relatively more, and angle still is difficult to reach designing requirement.
2, be designed to a plurality of different light-emitting directions to the LED exiting surface, realize the full angle bright dipping.The advantage of this scheme is that light effect more even relatively, and rising angle is big.Shortcoming mainly is to make complex manufacturing, the assembling difficulty, and production cost is high, for the heat radiation cup is not in the light, must strengthen the ball cover size simultaneously, the rim of a cup footpath that reduces to dispel the heat, then the heat-sinking capability of heat radiation cup also descends thereupon.
3, planar light source adds the bright dipping of fluorescence sphere of powder bubble technology realization full angle again through adding border (or reflection shield): this scheme major advantage is that rising angle is big, and shortcoming is that LED light is through passing through border, lampshade; The light loss ratio is big, makes the LED cost increase, in addition owing to the reason of passing through border or reflection shield; The ball bubble is easy to occur the bright dark circle of light when lighting; For the heat radiation cup is not in the light, must strengthen the ball cover size simultaneously, the rim of a cup footpath reduces to dispel the heat; Then the heat-sinking capability of heat radiation cup also descends thereupon, has also increased the cost that passes through the border in addition.
4, planar light source is realized the full angle bright dipping through the method that adds the fluorescent material diffusion shell and add bulb again: it is very even that this scheme major advantage is that product goes out light effect.Major defect is that LED light is big through fluorescent material diffusion shell and the two-layer Lacquer finish loss of lampshade; Increased the LED cost, the cost of fluorescent material inner cover is also very high in addition, simultaneously for the heat radiation cup is not in the light; Must strengthen the ball cover size and reduce to dispel the heat rim of a cup directly, then the heat-sinking capability of heat radiation cup also descends thereupon.
Above the dimension scale of several kinds of scheme ball bubbles of realizing wide-angles relatively large, make the heat-sinking capability variation of heat radiation cup, can't promote the heat-sinking capability of whole lamp, make the luminous flux of whole lamp receive certain restriction.
