Light source device and lamp

The invention relates to the technical field of illumination, in particular to a light source device and a lamp. The lamp comprises a light source device, the light source device comprises a frame, a lampshade and an end cover, the frame is used for assembling a lamp panel and provided with an insertion port, and the lampshade is inserted into the insertion port and clamped with the frame so that light emitted by the lamp panel assembled on the frame can be emitted out of the lampshade; the end cover is clamped to the end of the frame and abuts against the lampshade. According to the light source device, the stability of clamping the end cover to the frame can be improved, generation of gaps is reduced, the phenomenon of light leakage is reduced, and the assembling efficiency can be improved. 本发明涉及照明技术领域，具体而言，涉及一种光源装置和灯具；灯具包括光源装置，光源装置包括边框、灯罩和端盖，边框用于装配灯板，边框设置有插接口，灯罩插接于插接口，且与边框卡接，以使装配于边框的灯板发出的光线能从灯罩射出；端盖卡接于边框的端部，且与灯罩抵接。本发明的光源装置能够提高端盖卡接于边框的稳定性，减少缝隙的产生，减少漏光的现象，并且能够提高装配效率。
