Problems solved by technology

The second type is a light source based on ultra-high-power chips. Although the power of the light source can be made relatively large (up to 9W), since the chip is a whole, the optical design between the chips cannot meet the requirements of high-efficiency light extraction. Requirements or the overall light efficiency is low, so there are certain problems in the promotion
As for the COB light source, its size and power are too large, which cannot meet the needs of ultra-small 2-6w power light source

Embodiment 1

[0031] like figure 1 and figure 2 As shown, the LED light source module of this embodiment includes an LED module substrate 1 and four LED chips 2, one module of the LED module substrate 1 has an inverted trapezoidal platform structure 3, and the four LED chips 2 Encapsulated inside the inverted trapezoidal platform structure 3;

[0032] The angle of inclination of the side of the inverted trapezoidal platform structure 3 is 45-80 degrees, the optimal angle is 70 degrees, and the height is 2 to 4 times the thickness of an LED chip 2, that is to say, the side of the inverted trapezoidal platform structure 3 forms a slope On the one hand, it can solve the mass production of 2-9W light source modules, and at the same time facilitate the replacement of light source modules; The luminous efficiency of the chip 2 can effectively improve the color rendering and orientation of the module light source, and facilitate the implementation of the dispensing process of light export and l...

Embodiment 2

[0038] like Figure 4 and Figure 5 As shown, the LED light source module of this embodiment includes an LED module substrate 1 and nine LED chips 2, one module of the LED module substrate 1 has an inverted cone-shaped frustum structure 4, and the nine LED chips 2 is encapsulated inside the inverted conical frustum structure 4;

[0039] The angle of inclination of the side of the inverted conical frustum structure 4 is the same as that of Embodiment 1, and also forms a slope, which can also achieve the same effect as that of Embodiment 1;

[0040] The nine LED chips 3 are packaged in a 3-5mm space inside the inverted cone-shaped frustum structure 4. 2 Within the range of the area, since the power of each LED chip 3 is 0.5W ~ 1W, nine LED chips 3 can reach 4.5W ~ 9W; nine LED chips 3 are arranged in five rows, the first row and the fifth row All are one LED chip 3, the second row and the fourth row are two LED chips 3, and the third row is three LED chips 3, from image 3 I...

Abstract

The invention discloses a high-power LED multi-chip light source module, which includes an LED module substrate with an internal circuit design and a plurality of LED chips, one module of the LED module substrate has an inverted trapezoidal platform or an inverted cone The platform structure, the plurality of LED chips are packaged inside the inverted trapezoidal platform or inverted tapered platform structure. The present invention designs an inverted trapezoid or inverted cone structure in a module of the LED module substrate, so that multiple LED chips can be packaged inside the inverted trapezoid or inverted cone structure, on the one hand, it can solve the problem of 2-9W light source The mass production of the module is convenient for the replacement of the light source module. On the other hand, the side of the inverted trapezoidal table or the inverted conical table structure is inclined at a certain angle, thereby forming a slope. Due to the influence of the slope, the light emitted by the LED chip can be Concentrate and emit upwards to improve the luminous efficiency of the LED chip, and at the same time effectively improve the color rendering and orientation of the module light source.

Description

technical field [0001] The invention relates to a light source module, in particular to a high-power LED multi-chip light source module, which belongs to the field of LED light sources. Background technique [0002] At present, there are mainly two types of LED light source structures, one is the light source packaged by a single chip, such as 303, 4040, 5050, 5730, etc. Due to the limitation of chip size and power, the maximum power used in the market is generally 1W. . The second type is a light source based on ultra-high-power chips. Although the power of the light source can be made relatively large (up to 9W), since the chip is a whole, the optical design between the chips cannot meet the requirements of high-efficiency light extraction. Requirements or the overall light efficiency is low, so there are certain problems in the promotion. As for the COB light source, its size and power are too large, which cannot meet the needs of an ultra-small 2-6w power light source....
