Light source device

In particular, it provides a kind of liquid that can be used to abut the external pressure to prevent deformation and damage of the body. When used in water, it can prevent external water and impurities from infiltrating into the interior of the seat to avoid A light source device in which the light-emitting module is short-circuited and can improve the pressure resistance and the service life.

According to the current practice, there are many types of light source devices and their use. In addition to being used as general lighting for indoor or outdoor use, fishing boats are often equipped with a light source device that collects light to induce fish accumulation on the sea surface, or directly The light source device is placed in the water to project light for use as an underwater illumination.

Please refer to FIG. 1 , which is the invention patent of Taiwan No. 1353435 "underwater illumination". The underwater illumination lamp 10 is provided with a base 111 on a lamp housing 11 , and the outer surface of the base 111 is provided. The heat dissipating fins 112 are provided with a side wall 113. The side wall 113 is provided with two first openings 114, and a lens 12 is disposed at one end thereof, and an accommodating space 115 is formed in the lamp housing 11. The solid-state light-emitting device 13 is provided with a package substrate 131 connected to a power source on the surface of the base 111 of the lamp housing 11. The solid-state light-emitting element 132 is electrically connected to the package substrate 131, and the solid-state light-emitting element is sealed with a transparent package 133. 132. The solid-state light-emitting device 13 is covered with a transparent water-repellent layer 14, and a sealing member 141 is disposed between the transparent water-repellent layer 14 and the surface of the base 111 of the lamp housing 11 to enhance sealing waterproofness; When the lamp 10 is placed in water, the water liquid can fill the accommodating space 115 through the first opening 114 of the lamp housing 11, and emit light in the solid state. A water layer 15 is formed between the device 13 and the lens 12, and the light of the solid-state light-emitting element 132 is emitted through the transparent package 133, the transparent water-repellent layer 14, the water layer 15 and the lens 12 for use as underwater illumination; The underwater light 10 still has the following drawbacks in use:

1. When the underwater light 10 is placed in water, the solid-state light-emitting device 13 is immersed in the aqueous liquid, and the solid-state light-emitting device 13 is covered with a transparent water-repellent layer 14 and sealed with a sealing member 141 to prevent solid-state light. The package substrate 131 of the device 13 is short-circuited. However, when the water pressure around the underwater light 10 is large or the sealing member 141 is aged, the water still penetrates into the transparent water-repellent layer 14, and the package substrate 131 of the solid-state light-emitting device 13 is easily caused. The solid-state light-emitting element 132 is short-circuited and damaged, thereby affecting its service life.

2. When the underwater light 10 is placed in the water, the liquid liquid fills the accommodating space 115 through the first opening 114 of the lamp housing 11, and the accumulated space in the accommodating space 115 of the lamp housing 11 is easily soiled. The first opening 114 of the lamp housing 11 is provided with a filter screen to prevent debris from entering the accommodating space 115 of the lamp housing 11. However, the filter system can only block the bulky debris, and some fine impurities will still enter. It is deposited in the accommodating space 115 of the lamp housing 11, thereby affecting the lighting effect.

3. The package substrate 131 of the solid state light emitting device 13 is in contact with the inner surface of the base 111 of the lamp housing 11. Therefore, the heat generated by the solid state light emitting device 132 is first conducted to the package substrate 131 and then transmitted to the lamp housing via the package substrate 131. The pedestal 111 of the pedestal 111 is dissipated by the heat dissipating fins 112 on the outer surface of the pedestal 111. However, there is often a gap between the encapsulating substrate 131 and the inner surface of the susceptor 111, and the gap will block between the package substrate 131 and the pedestal 111. The heat is transferred, which in turn affects the heat dissipation effect.
