Because the ambient light in the deep sea is very dark, it is necessary to use the illuminator-assisted photographic device to effectively observe. In order to adapt to the extreme environment of the deep sea, the illuminator generally must meet high illuminance, low power consumption, leakage prevention, and high water pressure resistance. , collision resistance, good heat dissipation and other needs. As shown in FIG. 1 , a waterproof lighting lamp of the prior art, comprising a main housing 1 having an external thread 101 and a plurality of driving holes 102 for assembly or disassembly, is disposed at the front end of the main housing 1 and a lamp cap module 2 having a lamp holder 201, an LED lamp group 202 and a light transmissive sheet 203, a lamp cover 3 disposed at the front end of the main casing 1 and having an internal thread 301 screwed to the external thread 101, a seal ring 4 disposed between the front end of the main housing 1 and the rear end of the lamp holder 201, a buffer ring 5 disposed between the lamp holder 201 and the lamp cover 3, and a buffer ring 5 disposed on the main housing 1 Waterproof connector 6 on the rear end. When the lamp cover 3 is locked with the main housing 1 , the lamp cover 3 can be pushed against the lamp 201241361 seat 201 via the buffer ring 5 , and the sealing ring 4 is pressed against the main housing 丨 and the lamp holder 2 .

Light. However, such a waterproof lighting lamp has the following disadvantages in actual use: 1. In the deep sea environment, the metal is highly susceptible to corrosion oxidation, and therefore, the snail between the main casing i and the lampshade 3 When the tooth is smelted, there is a problem that the main casing 1 and the lamp cover 3 cannot be disassembled. If the user uses a detaching tool (not shown) to join the driving holes 1 〇 2, the rigorous force is hardened. When the lamp cover 3 is detached, the thread between the main casing 丨 and the lamp cover 3 must be broken, and the main casing 1 also loses the protection of the anti-corrosion film at the driving holes 102. The main casing i can no longer be screwed tightly with the lampshade 3, and the main casing is easily corroded, which is unbearable. At this time, even if other parts are not damaged, the waterproof lighting lamp can be completely The situation in which the group is scrapped. 2. The waterproof light is tapped on the main casing to screw the lamp cover 3. However, for the load of the water downloading device, the weight of the main casing i cannot be excessively heavy. Therefore, in the main The tapping length on the casing cymbal cannot be too long to prevent the main casing 1 from being overweight, however, this limits the bonding strength of the main casing 1 to the lampshade 3. 3. The waterproof light can only use the main casing 1 and the lampshade 3 to help dissipate the heat energy of the lamp cap module 2 to the outside, and the heat dissipation area is small and the effect is limited. 201241361 4. The waterproof light is protected by the light cover 3 only by the light cover 3, and the foreign matter having an outer diameter smaller than the aperture of the cover 3 cannot be prevented from colliding with the transparent cover 203.
