Technical field
The utility model relates to a kind of lighting technical field, especially relates to a kind of good heat dissipation effect, good airproof performance, the wide tunable optical toning COB LED structure of adjustable extent.
Background technology
Existing tunable optical toning LED encapsulating structure is: a kind of is many integrated (like the A schemes, last figure seven) of sending out the LED lamp pearl of different colours light, and these LED lamp pearls generally are high-power LEDs; Whole packaging cost is high, and packaging density is low, and mixed light colour mixture chromatic effect is poor, and adjustable light color is poor; Also have and adopt the COB encapsulation scheme, but simple two-dimensional plane mode just, chip is not directly to contact with substrate, but earlier through the extremely low line layer of one deck conductive coefficient; The integral heat sink poor, and all be positioned at substrate surface, there is not the reflector, it is also bad to go out light effect; The plastic packaging material lead frame and the substrate adherence of pressing are bad, phenomenons such as glue can occur leaking, and moisture in the environment and pernicious gas also infiltrate in the packaging body easily, reduce useful life greatly; In addition, sending out the arranging of chip of different colours light and also do not consider the effect of mixed light, is simple array; Be used as sealing simultaneously with the fluorescent glue of the compound generation white light of blue chip, directly contact, greatly reduce the light extraction efficiency of light modulation toning effect and chip with ruddiness (gold-tinted); In use simultaneously, the decay of white light and reddish yellow light is inconsistent, and photochromic drift is serious.Like application number is 201010253905.1; Name is called China's invention application of chip integrated always high-power LED encapsulation technology and products thereof; It comprises wiring board, led chip, fluorescent coating and silica gel type body, and said silica gel type body surrounds end to end close-shaped in the circuit board, and the led chip setting in the circuit board; Fluorescent coating is coated on the led chip surface through binder, and led chip and fluorescent coating all are limited in close-shaped that the silica gel type body surrounds.This LED encapsulating products just has above-mentioned shortcoming, the luminescence chip setting in the circuit board, radiating effect is poor; And luminescence chip is arranged on the PCB surface, does not have reflector layer, and it is bad that luminescence chip goes out light effect; Adherence is bad between silica gel type body and the wiring board, occurs leaking the glue phenomenon easily.
Summary of the invention
The utility model mainly is that the arranging of chip that solves different colours light among the tunable optical toning COB LED do not considered the effect of mixed light; The problem of the light extraction efficiency difference of light modulation toning effect and chip, the tunable optical toning COB LED structure that the light extraction efficiency that provides a kind of light modulation to mix colours effect and chip is good.
The utility model also solved the radiating effect that tunable optical toning COB LED encapsulating structure exists in the prior art poor, go out light effect and the bad technical problem of air-tightness, the tunable optical toning COB LED structure of a kind of heat radiation, bright dipping, good sealing effect is provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of tunable optical toning COB LED structure; Comprise substrate and be arranged on the line layer on the substrate; On substrate, be provided with several cone tanks; The bottom surface of cone tank is provided with a plurality of small-power luminescence chips one, and cone tank is " mutually " font and distributes on substrate, on substrate, also be provided with several small-power luminescence chips two; Said luminescence chip two is " three " font and distributes, and said cone tank and luminescence chip two are crisscross arranged together.Cone tank and luminescence chip two crisscross layouts have improved the light emission rate of tunable optical toning effect and chip, have weakened the phenomenon of photochromic drift.Adopt the three-dimension packaging pattern in the utility model, luminescence chip is arranged on the cone tank bottom surface, makes luminescence chip directly contact with substrate, band-type brake high-cooling property and low light decay, improved packaging density again, the while manufacturing cost is also lower.Luminescence chip sinks in the cone tank of substrate in the utility model, and this cone tank structure has improved the light effect that of luminescence chip
As a kind of preferred version, in said cone tank, be filled with fluorescent glue, on substrate, also be provided with a corral wall glue, said enclosure wall glue is trapped among cone tank wherein, in enclosure wall glue, is filled with transparent adhesive tape.。Substrate is provided with enclosure wall glue, has guaranteed the air-tightness and the physical strength of encapsulation, and the transparent glue of enclosure wall glue institute region spot printing sealing is realized sealing and protection to chip gold thread etc.
As a kind of preferred version, luminescence chip links to each other with line layer through routing.Heat sheds through the high substrate of conductive coefficient, and radiating effect is better, and electric current has so just constituted a kind of thermoelectric isolating construction through the line layer of substrate surface, has improved LED designed life and long-time stability.
As a kind of preferred version, the luminescence chip one that is arranged in the said cone tank is blue chip, and the said luminescence chip two that is arranged on the substrate is red light chips or gold-tinted chip.The compound generation white light of blue chip and fluorescent glue, red light chips or gold-tinted chip and the crisscross layout of cone tank through control and regulate electric current, can realize photochromic and brightness adjustable in the suitable wide region.
As a kind of preferred version, said cone tank is bowl-shape, and the aperture area of cone tank is greater than the area of bottom surface.This bowl-shape cone tank forms a reflection shield structure, makes the bright dipping better effects if of luminescence chip.
Therefore, the utility model advantage is: 1. luminescence chip is arranged on the cone tank bottom and directly contacts good heat dissipation effect with substrate; 2. luminescence chip dispels the heat through substrate, and electric current has constituted a kind of thermoelectric isolating construction through the line layer of substrate surface, has improved LED life-span and stability; 3. enclosure wall glue has guaranteed the air-tightness and the physical strength of encapsulation; 4. the white light and the red/gold-tinted chip interlaced arrangement that produce of blue chip and fluorescent glue realizes the adjustable of photochromic and brightness that suitable wide region is interior.
