Description
Technical field
The utility model belongs to the LED lighting technical field, relates to a kind of light source module, relates in particular to the white light LED light source module of a kind of COB of employing technology and array interconnection.
Background technology
COB (Chip On Board) led light source is a plurality of LED (light emitting diode) chip, directly is bonded on the substrate, by gold thread or bump a plurality of chips and power supply is coupled together; Cover transparent silica gel at chip again, both chip and gold thread played a protective role, again because of the refraction coefficient of silica gel greater than 1, thereby increase the light extraction efficiency of LED.If expect white light source, answer mixed fluorescent powder in the hope of reaching the white light effect in the transparent silica gel.The advantage of COB light source is: 1, light-emitting area is large, can as required, do infinitely greatly in theory; 2, thermal conductivity is good, and the thermal conductivity of aluminium base is very high, can effectively derive the heat energy that LED produces when luminous; 3, at the bottom of the cost, because there is not the led chip package casing, can reduce the expense of material and processing; 4, make simply.White light LED lamp of the prior art generally is that the led chip that produces blue light is close to phosphor layer and is encapsulated in the confined space with the formation white light LEDs.Chinese patent discloses the white light LED light source module that one kind of CN201373272 adopts COB technology and array interconnection, it is characterized in that comprising: have opening module housing, be arranged on module housing inside circuit board, be arranged on led chip array on the circuit board, high printing opacity light-emitting plate that the led chip array package is hidden at the chip package glue on the described circuit board, with the opening of described module housing, be coated with the lip-deep phosphor layer that is located on the high printing opacity light-emitting plate more near described led chip with array format.Form an integral body owing to produce blue-light LED chip and phosphor layer, both can't be separated from each other, the uniformity of fluorescent material is difficult to control, and then causes the brightness uniformity of the last white light LEDs finished product that forms poor, and is difficult to adjust afterwards in the finished product manufacturing colour temperature of finished product white light LED lamp; Because the total reflection principle (SellLaw) when light is walked between two kinds of different mediums, the phosphor layer light extraction efficiency is limited, the light angle of the light that sends when chip is during greater than the critical angle of phosphor layer and Air Interface, this part light will can't be derived by total reflection, this part light, through repeatedly reflecting and refraction (if fluorescent powder grain is arranged) in the phosphor layer the inside, do not fail to enter into air if be less than critical angle, heat energy will be changed into and thereby to lose light extraction efficiency low, and heat energy impels the operating temperature of fluorescent material higher, finally accelerated the aging attenuation process of fluorescent material, reduce the life-span of fluorescent material, finally affected the service life of whole white light LED lamp.
Summary of the invention
