Embodiment 1

[0036] see Figure 1 to Figure 8 As shown, it is Embodiment 1 of the present invention. This embodiment discloses a light source device 100, which includes a substrate 1, an electronic component 2 mounted on the substrate 1, a surrounding wall 3 arranged on the substrate 1, fixed on the inner edge of the surrounding wall 3 and electrically A metal cover 4 coupled to the substrate 1, a light-transmitting member 5 arranged on the enclosure wall 3, a cover plate 6 arranged on the light-transmitting member 5 and fixed on the enclosure wall 3, an electrical A detection unit 7 coupled to the substrate 1 and a spacer 8 provided on the substrate 1 .

[0037] It should be noted that although the light source device 100 is described as including the above-mentioned components in this embodiment, the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the light source device 100 can also omit some components (such as: the meta...

Embodiment 2

[0077] see Figure 9 to Figure 11 As shown, it is the second embodiment of the present invention. This embodiment is similar to the above-mentioned embodiment, so the similarities between the embodiments (such as: the substrate 1, the electronic component 2, the metal cover 4, and the raised block 8) will not be repeated, and the present embodiment The features different from the above-mentioned embodiments are generally described as follows:

[0078] Such as Figure 9 with Figure 10 As shown, in this embodiment, the light source device 100 omits the cover plate 6 and the protective layer 9, and the enclosure wall 3 is recessed from its top surface to form an opening corresponding to the position of the metal cover 4 411 of a configuration groove 31 (that is, at least part of the driver chip 23 is covered by the above-mentioned metal cover 4 and the above-mentioned wall 3), and the above-mentioned wall 3 can also be formed with a rubber channel and escape at the bottom of ...

Embodiment 3

[0084] Such as Figure 12 with Figure 13 As shown, the light source device 100 is substantially the same as the second embodiment, the difference is that the enclosure wall 3 cancels the arrangement groove 31 carrying the light-transmitting member 5, and the enclosure wall 3 is formed with a light-transmitting hole corresponding to the position of the light-emitting unit 21. 36, the light-transmitting member 5 is arranged on the inner side of the wall 3 and covers the light-transmitting hole 36; Stick to the inner surface of the enclosure wall 3 loam cake by the way of reverse sticking. The light source device 100 can be provided with the detection unit 7 as in the above-mentioned embodiment, and the transmission line 72 of the detection unit 7 can be formed inside the enclosure wall 3, or can be formed on the enclosure wall 3 as in the second embodiment. On the outside, the detection circuit 71 of the detection unit 7 can be arranged on the top surface or the bottom surfac...

Abstract

A light source device includes a substrate, a light emitting unit, a frame, a light permeable member, a cover plate, and a detection unit. An upper electrode layer and a lower electrode layer of the substrate are respectively arranged on two opposite sides of the substrate, and are electrically coupled to each other. The light emitting unit is disposed on the upper electrode layer. The frame is disposed on the substrate and surrounds the light emitting unit. The light permeable member is disposed on the frame and covers the light emitting unit. The cover plate is disposed on the light permeable member and is fixed to the frame. The detection unit includes a detection circuit formed on the light permeable member or the cover plate and two transmission circuits formed on the frame. The detection circuit is electrically coupled to the upper electrode layer through the two transmission circuits. Therefore, the light source device adopts a structure different from TO-CAN packaging so as tomeet various different requirements nowadays.

Description

technical field [0001] The invention relates to a light source device, in particular to a light source device adopting a new packaging structure. Background technique [0002] Most of the existing light source devices are packaged in TO-CAN (Transistor Outline-CAN Transistor Outline Can). In recent years, there has been no significant structural improvement, so it is gradually difficult to meet various requirements. Therefore, the inventor believes that the above-mentioned defects can be improved, Naite devoted himself to research and combined with the application of scientific principles, and finally proposed an invention with reasonable design and effective improvement of the above-mentioned defects. Contents of the invention [0003] The embodiment of the present invention is to provide a light source device, which can effectively improve the possible defects of the existing light source device. [0004] The embodiment of the present invention discloses a light source ...
