In such a way, the blue light emitted by the LED excites the yellow fluorescent powder or the purple and ultraviolet light excites the tribasic fluorescent powder to obtain the uniform white light, thus obtaining the white light LED bulb with higher quality and low price.
Description
Technical field
The utility model belongs to LED encapsulation and led light source lighting technical field.
Background technology
Present white LED lamp generally adopts blue chip to excite the white light LEDs element of yellow fluorescent powder to make.The fluorescent material of traditional white light LEDs element is adjacent around led chip, owing to the heat effects of led chip when working quickened its decay to fluorescent material, influences its service life.And the white light LEDs element complex manufacturing technology of this form, operation is a lot, and for the control that reaches LED fluorescent lamp colour temperature and luminous evenly, must carry out the photoelectricity screening of strict control and finished product to the production technology of LED element, the screening stepping is a lot, cost of manufacture is very high, and system radiating also is difficult to handle, and effect is also not ideal.
Summary of the invention
The deficiency that the utility model exists at prior art, purpose provides a kind of diverse white light mode of excitation, makes the white light LEDs bulb, and technology is simpler, and is workable, and cost is lower.
The technical solution of the utility model is as follows:
A kind of LED bulb of different white light mode of excitation, it is to adopt blueness, purple or ultraviolet LED element to form the LED luminescence unit, the LED luminescence unit is installed on the aluminium alloy seat, and the position corresponding with the LED luminescence unit adds lid layer optical resin housing on the aluminium alloy seat, described optical resin housing contains yellow or three primary colors fluorescent powder (promptly fluorescent material directly being joined in the material of resin cover plate), or surface-coated has one deck yellow or three primary colors fluorescent powder.Aluminium alloy seat and the optical resin housing on it are combined to form bulb-shaped, aluminium alloy seat top connects lamp holder, the LED luminescence unit is electrically connected with driving power by lead, and driving power is arranged in the aluminium alloy seat, and the lead that is connected with driving power is used by lamp holder and drawn positive and negative electrode.Blue-light excited yellow fluorescent powder that LED sent like this or purple light, ultraviolet excite three primary colors fluorescent powder, obtain uniform white light thus.Thereby can obtain out the white light LEDs bulb of high-quality low-cost more.
Described luminescence unit is welded on common line plate or the aluminium base wiring board by direct insertion or adopting surface mounted LED element to be formed, or directly is packaged with the aluminium base luminescence unit (adopting the COB technology of the aluminium base luminescence unit of direct packaging LED chips) of led chip.
Described optical resin cover plate adopts the PC material of transparent or scattering.
Advantage of the present utility model:
1, breaks through the manufacturing technology bottleneck of encapsulation of conventional white light LED element and LED bulb, improved the uniformity control technological problems during conventional white light LED element is made.Make the operability of LED white light infusion fabrication technique improve greatly, help large-scale production in batches.
2,, thereby reduced fluorescent material attenuation problem at high temperature greatly because this technology is separated certain distance with fluorescent material and LED luminescence chip.Make prolong greatly the service life of white light LEDs bulb.
3, adopt the COB technology of direct packaging LED chips on the aluminium base printed substrate, and utilize the fin on the aluminium alloy pedestal treatment system to dispel the heat, thereby effectively reduce the LED light decay.
4, simple in structure, good manufacturability, the qualification rate height has reduced the manufacturing cost of white light LEDs bulb, makes its market fit scope more extensive.
Description of drawings
Fig. 1: be the profile of a kind of concrete structure of the present utility model;
The specific embodiment
Now further specify present technique in conjunction with the accompanying drawings:
Referring to Fig. 1, on aluminium base printed substrate 1, be packaged with blueness or purple, ultraviolet led chip 2, aluminium base printed substrate 1 is fastened in the groove of an aluminium alloy seat 3, is stamped optical resin housing 4 on light-emitting area.Inner surface at optical resin housing 4 scribbles yellow or three primary colors fluorescent powder 5.6 is the LED driving power, also is installed in the aluminium alloy seat 3, and it realizes being electrically connected with the led chip 2 on the aluminium base printed substrate 1 by lead.Driving power 6 and aluminium base printed substrate 1 heat when work can be delivered to by the radiating fin on the aluminium alloy seat 3 among the air.Aluminium alloy seat 3 and the optical resin housing 4 on it are combined to form bulb-shaped, connect lamp holder 7 on the top of aluminium alloy seat 3, and draw positive and negative electrode with lead by lamp holder 7.
Adopting present technique can be made into the profile the same with conventional bulb is directly installed on the lamp holder of conventional lamp.In different environments for use, can make diameter 61mm, 76mm, 81mm, 91mm according to watt level and needs, 111.5mm, 131.5mm or other size.
