Therefore, LED lamp tube is high owing to having light efficiency, and thermal resistance is low, and color rendering is good; In human eye, do not produce aberration, depending on seeing that resolution is high, good contrast, light penetration capacity is strong; Luminous efficiency is high, and photoelectric conversion efficiency is high; Also there is dazzle-free, life-span long (can reach 50,000 hours), light decay little (light decay only had 3% in 8000 hours); For semiconductor material, environment friendly and pollution-free, little power consumption; And be solid-state cold light source, the fail safe of its live line work and drive characteristic good, will be the main force of room lighting.
But the LED module in traditional LED lamp pipe needs first then to cross Reflow Soldering through paster board paster adding man-hour, and processing technology is many, process is complicated, compares expense manpower, and production timeliness is slow.In addition, LED module adopts the aluminium base with multi-layer compound structure to carry out paster or die bond, as shown in Figure 1, aluminium base 11 is respectively arranged with insulating barrier 12, layers of copper 13 and turmeric layer 14, LED chip 16 passes through crystal-bonding adhesive 15 die bond in the upper surface of turmeric layer 14, and accesses Power supply by the pad that gold thread 18 and turmeric layer 14 are arranged.It can thus be appreciated that the aluminium base cost of existing multi-layer compound structure is high, and consumptive material is many, complex manufacturing technology, thus limits the popular of LED lamp tube and promote the use of.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of LED module based on minute surface aluminium, and this LED module utilizes the reflective of mirror-surface aluminum base board, and by direct for LED chip die bond in mirror-surface aluminum base board, technique is simple, saving material, and light efficiency is good.
For achieving the above object, a kind of LED module based on minute surface aluminium of the utility model statement, its key is: comprise mirror-surface aluminum base board and multiple LED core lamellar body, described LED core lamellar body fits in the upper surface of described mirror-surface aluminum base board by crystal-bonding adhesive, described mirror-surface aluminum base board is also provided with two pads, multiple LED core lamellar body is electrically connected between two pads by gold thread, and each described LED core lamellar body is covered with fluorescent glue.
In this programme, LED core lamellar body is directly fitted in aluminium base upper surface by crystal-bonding adhesive, eliminates the paster in traditional handicraft and cross the courses of processing such as Reflow Soldering, saving human cost; Adopt mirror-surface aluminum base board as die bond substrate simultaneously, not only eliminate the layer structure such as turmeric layer, layers of copper, insulating barrier in traditional handicraft, reduce Material Cost, and mirror-surface aluminum base board reflective is better, the light efficiency of LED module can be improved, reduce energy waste.
Further technical scheme is, described mirror-surface aluminum base board is rectangular slab, fixes described pad at the two ends of this mirror-surface aluminum base board, and multiple LED core lamellar body is serially connected between two pads by gold thread.
By said structure, not only make this LED module can better adapt to existing LED lamp tube, by the serial connection mode of connection, contribute to reducing workload, thus be convenient to control cost.
Further technical scheme is, multiple described LED core lamellar body is array distribution along the length direction of described mirror-surface aluminum base board.
Employing array distributes, and is not only convenient to processing, and contributes to improving LED module light efficiency, and makes it evenly luminous.
Further technical scheme is, is symmetrically arranged with reinforcement at the dual-side of described mirror-surface aluminum base board.
By arranging reinforcement, enhancing the mechanical strength of described mirror-surface aluminum base board, being not only convenient to transfer in process of production, and contribute to the useful life of improving LED.
Further technical scheme is, preferred described fluorescent glue is coated in the upper surface of described LED core lamellar body.
Further technical scheme is, in order to improve the light efficiency of LED chip, described fluorescent glue is guarantor's type glue, and is covered on described LED core lamellar body by some glue.
Remarkable result of the present utility model is: by direct for LED core lamellar body die bond above aluminium base, eliminates the paster in traditional handicraft and crosses the courses of processing such as Reflow Soldering, saving human cost; Adopt mirror-surface aluminum base board as die bond substrate simultaneously, not only eliminate the layer structure such as turmeric layer, layers of copper, insulating barrier in traditional handicraft, reduce Material Cost, and mirror-surface aluminum base board reflective is better, the light efficiency of LED module can be improved, reduce energy waste; This LED module light efficiency is high, and thermal resistance is low, and Light distribation is even, without dazzling light.
