Abstract
The utility model discloses an integrated eutectic light source based on an aluminum substrate. The integrated eutectic light source comprises multiple eutectic EMC light sources and the aluminum substrate, wherein the eutectic EMC light sources are bonded onto the aluminum substrate. The light source of the utility model is good in heat conduction performance, and conducive to large-scale paster production.
Description
Technical field
The utility model relates to a kind of light source, relates in particular to the integrated-type eutectic light source based on aluminium base, belongs to lighting field.
Background technology
Along with the rising of people's environmental consciousness and energy-conservation requirement, LED light source has replaced traditional light source at present becomes the first-selected product in high-power illumination field.The general support adopting of existing high-power integrated type LED light source is red metal (silver-plated), and price is relatively high, and light source production technology is comparatively complicated, and especially production efficiency is low, is difficult to realize the automation of producing; All there is the problem that cost performance is not high in traditional integrated serial light source simultaneously because power is less; This type of simultaneously traditional circuit of light sources is simple in structure, and maintainable poor, once go wrong, maintenance cost is very high.
Summary of the invention
For the defect of prior art, the utility model discloses a kind of integrated-type eutectic light source based on aluminium base, can realize automation paster and produce, can realize higher brightness, easy care, long-life.
For achieving the above object, the utility model is produced by following technical proposals:
Integrated-type eutectic light source based on aluminium base, comprises eutectic EMC light source, aluminium base, and eutectic EMC light source is bonded on aluminium base.
In above-mentioned, eutectic EMC light source refers to that the encapsulation of LED lamp pearl adopts EMC material (epoxy resin) molded packages, realizes the interconnection of LED chip and EMC support on EMC support by eutectic technology.On market, existing multiple this type of finished product is being sold, such as the APT EMC3030 of brilliant section electronics, APT EMC2835, APT EMC3014, APT EMC3020 etc.With respect to traditional LED lamp pearl, in Same Efficieney situation, the in the situation that of the aobvious finger of height (RA > 80), eutectic EMC light-source brightness exceeds more than 20% than traditional integrated optical source especially.Use different-colour or different monochromatic eutectic EMC light source can meet the requirement of different field to illumination.
In above-mentioned, aluminium base conductive coefficient is high, and thermal resistance is little, is conducive to adopt chip mounter to carry out mass automatic production and mounts, and enhances productivity.
Preferably, described eutectic EMC light source is multiple, is evenly distributed on aluminium base.
Above-mentioned distribution of light sources can be adjusted as the case may be, common arrangement adopt 10w-10 string 1 also, 20w-10 string 2 also, 30w-10 string 3 and circuit design.
Preferably, described eutectic EMC light source is bonded on aluminium base by tin cream, light source is lighting the heat producing in the course of work, rely on the integrated superhigh radiating structure of chip set, be welded on integration aluminum substrates and can be formed a more excellent heat radiation channel by the tin cream of high thermal conductivity, light source uses more reliable and more stable.
Meanwhile, light-source structure has been realized wireless penetration design, its direct calcaneus branches frame is combined by gold-tin alloy by the chip of upside-down mounting, there is no traditional gold thread Welding Structure.Light source is more secure and reliable to use like this.
The test that applicant carries out shows, integrated-type eutectic light source of the present utility model has excellent heat dispersion, effectively ensure the useful life of high-power lower product: by frivolous vertical heat dissipation channel, effectively reduce thermal resistance, adopt the tin cream (67w/mk) of high thermal conductivity coefficient, 3 times of elargol that its heat conductivility adopts up to conventional light source, 10 DEG C/w of integrated optical source overall thermal resistance <; Owing to having used the light source of eutectic EMC encapsulation, effectively ensured the heat-resisting ability of product, high temperature resistant reaching more than 250 DEG C simultaneously, and ultraviolet radiation resisting ability is very excellent, at 120 DEG C, 365nm ultraviolet irradiation 1h, change 3%, compare traditional material and exceed more than 10%.
Brief description of the drawings
Fig. 1,2,3 is respectively end view, front view, the stereogram of the utility model light source.
Embodiment
Shown in accompanying drawing 1,2, integrated-type eutectic light source of the present utility model, comprises multiple equally distributed eutectic EMC light sources 1, is all bonded on aluminium base 2 by tin cream.
Wherein, above-mentioned eutectic EMC light source can be mono-light source of different monochromatic eutectic EMC, meets the requirement of different application field to different colours.
Wherein, single eutectic EMC light source of white light that above-mentioned eutectic EMC light source can also be different-colour, replaces existing indoor and outdoor white-light illuminating.
The preparation method of the utility model light source is mounted on eutectic EMC light source on aluminium base by tin cream, then it is positioned among heating platform or reflow soldering in batches, after tin cream fusing by single light source and aluminium base tightly welding be integrated.
The parameters such as the size providing are in the accompanying drawings only signal, not form and are particularly limited.
Claims (3)
1. the integrated-type eutectic light source based on aluminium base, is characterized in that comprising eutectic EMC light source, aluminium base, and eutectic EMC light source is bonded on aluminium base.
2. light source according to claim 1, is characterized in that described eutectic EMC light source is multiple, is evenly distributed on aluminium base.
3. light source according to claim 1, is characterized in that described eutectic EMC light source is bonded on aluminium base by tin cream.
