Abstract
The utility model relates to a LED encapsulation illumination field especially relates to a LED light source module, mainly includes base plate and LED chip, the substrate surface both sides are equipped with the electrode, the LED chip is circular high density and arranges on the substrate surface, LED chip surface is equipped with even fluorescent coating. The beneficial effects of the utility model are that: simple structure, convenient and practical, the LED chip size is little, and be the square, a plurality of chip booths are apart from arranging on the base plate, the totality appear be one circular. Can obtain output more high -power, bigger lumen in less physical space, and the light -emitting is even, the reliability is high, and the radiating effect is good.
Description
Technical field
The utility model relates to LED lighting field, particularly relates to a kind of LED light source module.
Background technology
LED is because having efficient, safety, energy-saving and environmental protection, life-span long feature, and at lighting field, increasing people selects LED as light source.Along with the enforcement of China's energy-saving and emission-reduction policy, green illumination has incorporated energy-conservation key project.
Although the luminous efficiency of LED is very high in theory, actual efficiency only has about 30 percent.This just means the output wanting to obtain more high-power, higher lumen, must increase the quantity of LED light emitting source, but quantity increase means that physical size increases, and product design is limited to, and hinders the development of LED industry.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the LED light source module providing a kind of high-power, higher lumen to export.
For achieving the above object, the utility model can be achieved by the following technical programs:
A kind of LED light source module, comprise substrate and LED chip, described substrate surface both sides are provided with electrode, and on the surface of the substrate, described LED chip surface is provided with uniform fluorescent coating to the rounded high-density arrangement of described LED chip.Electrode is placed in substrate two side position, is convenient to later stage test and assembling, the multiple Small Distance high-density arrangement of LED chip, and as far as possible many LED chips of can arranging in less physical space, obtain the output of more high-power, larger lumen, and bright dipping are more even.
Further, described LED chip face-down bonding, at substrate surface, reduces the thermal resistance between LED chip and substrate.
Further, described LED chip is square, and specification is 1.6 × 1.6mm
2, much smaller than current LED chip specification.
Further, the material of described substrate is the aluminium nitride ceramics with LED chip similar thermal expansion coefficient, improves the heat-sinking capability of LED light source module.
Further, the two ends of described substrate are provided with semicircular indentations.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, and convenient and practical, LED chip size is little, and are square, and multiple chip Small Distance is arranged on substrate, is totally rendered as a circle.The output of more high-power, larger lumen can be obtained in less physical space, and uniform in light emission, reliability is high, good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
In figure: 1-LED chip, 2-substrate, 3-fluorescent coating, 4-electrode, 5-semicircular indentations.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described:
Embodiment 1
As shown in Figure 1, LED light source module described in the utility model, mainly comprises substrate 2, LED chip 1, fluorescent coating 3 and electrode 4.Substrate 2 is rectangular shape, and there is semicircular indentations at two ends, and substrate 2 Material selec-tion is the aluminium nitride ceramics with LED chip 1 similar thermal expansion coefficient.LED chip 1 is photochromic is blue light, and dimensions is 1.6 × 1.6mm
2, in square shape, several LED chips 1 adopt upside-down mounting die bond welding procedure Small Distance high-density arrangement on rectangular substrate 1, are totally rendered as circle, more LED chip 1 of arranging in less physical space as far as possible, and bright dipping is more even.LED chip 1 surface is provided with fluorescent coating 3, and fluorescent material is evenly coated in LED chip 1 surface, and the light that is combined into respective color photochromic with LED chip 1, light extraction efficiency is good, photochromic softer.Electrode 4 is fixed on the both sides on rectangular substrate 2 surface, is convenient to later stage test and assembling.
Embodiment 2
As shown in Figure 2, the present embodiment as different from Example 1 described substrate is round-shaped, and other structures are all identical with embodiment 1.
For a person skilled in the art, according to above technical scheme and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection range of the utility model claim.
Claims (5)
