Embodiment 1
[0061] The integrated vertical cavity surface emitting laser chip package structure of embodiment 1 is as follows Figure 5 shown.
[0062]The main material of the package substrate is copper, which is similar to the common LED (light emitting diode) package substrate. The light-emitting area on the substrate (for arranging the vertical cavity surface emitting laser integrated chip array) is a square with a side length of 22 mm.
[0063] The substrate includes positive and negative electrodes 3 connected to an external DC power supply, and also includes through holes 4 for fixing with an external heat sink.
[0064] The emission wavelength of the vertical cavity surface emitting laser chip 2 on the substrate is 940 nm, and the laser chip array is arranged in a square shape with a side length of about 12 mm. In order to display the spot shape, four vertical cavity surface emitting laser integrated chips 5 with an emission wavelength of 808nm are placed on the four corners of ...
Embodiment 2
[0073] use below Figure 6 The specific embodiment 2 will be described.
[0074] This facility example involves a short-wave infrared integrated medical light source system for rehabilitation medical equipment.
[0075] In this embodiment, the integrated VCSEL chip light source is exactly the same as the integrated light source in Embodiment 1.
[0076] The light source system includes a radiator, a fan for cooling the radiator, a lens barrel and a lens.
[0077] The heat sink is made of metal aluminum, copper, or high thermal conductivity ceramics.
[0078] The purpose of installing a fan on the radiator is to force the cooling of the aluminum radiator.
[0079] The substrate packaged with the integrated vertical cavity surface-emitting laser chip is fixed to the heat sink with screws through the fixing through holes, and thermal conductive glue is coated between the substrate and the heat sink.
[0080] The lens barrel is a cylindrical hollow structure with a length of 6...
Embodiment 3
[0085] use below Figure 7 To illustrate specific embodiment 3.
[0086] This facility example involves a household short-wave infrared integrated medical light source system for rehabilitation medical equipment.
[0087] The difference between this embodiment and Embodiment 1 is that the total number of chips is 36, including 32 940nm chips and 4 808nm chips.
[0088] The packaging of the integrated chip adopts the circuit connection mode of 12 series and 3 parallel, the rated current is 1200mA, and the voltage is 22-24V.
[0089] The difference between this embodiment and the specific embodiment 2 is that no combination lens is arranged in the lens barrel. The bottom of the lens barrel is connected to the aluminum heat sink, and the top (light outlet) is provided with a transparent window. The material is acrylic, and the thickness of the acrylic disc is 2mm. In order to make the outgoing light more uniform, the inner surface of the acrylic disc is covered with a layer of...
