Element, due to it have operating voltage is low, power consumption is small, luminous efficiency is high, emission response time is extremely short, it is photochromic it is pure, structure is firm
Gu, few and at low cost etc. the series of characteristics of shock resistance, vibration resistance, stable and reliable for performance, light-weight, volume, thus obtained wide
General application and the development advanced by leaps and bounds.
The one kind being commonly used is that COB light source is exactly conductive by bare chip or non-conductive adhesive is adhered on interconnection substrates,
Then it carries out wire bonding and realizes its electrical connection.
Traditional encapsulation mode is used since current COB encapsulation continues, bracket is bonded in heat dissipation base by heat treatment
On plate, chip is bonded on heat-radiating substrate by silica gel, over time, is easy to appear glue and is split phenomenon, heat-radiating substrate with
Bracket, chip are easily separated from, and lead to structural instability, are easy to appear light decay and dead lamp phenomenon, in addition, lead is welded to heat dissipation
On substrate, welding is taken time and effort, and increases cost.
Summary of the invention
The fixing type COB light source reasonable and practical the purpose of the utility model is to provide a kind of structure setting.
