Thus, it is prevented that moisture does not easily penetrate from the gap between the lens 170 and the outer frame 200 to increase the waterproof effect.

In the first embodiment, the plurality of fixing elements 210, such as screws or bolts, are further included, and the lamp housing 110 includes a plurality of assembling holes 112, and the fixing elements 210 are screwed through the assembly holes 112 to the lamp housing 110. That is, the first housing 120, the second housing 130, and the waterproof pad 140 are disposed with the assembly holes 112 at corresponding positions, so that the fixing members 210 are screwed and the components are fixed to the lamp housing 110. in.

When the maintenance personnel want to replace the light-emitting module 160 of different powers, the relevant fixing component 210 must be sequentially removed, and the second housing 130 and the waterproof pad 140 are removed, and the light-emitting module 160 can be replaced. In general, the larger the power of the light-emitting module 160 is, the larger the size, the corresponding opening 142 of the corresponding light-emitting module 160 and the opening 132 of the second casing 130 are correspondingly larger. Therefore, the waterproof pad 140 on which the light-emitting module 160 is mounted and the second housing 130 corresponding to the waterproof pad 140 must also be replaced together to meet the size thereof.

In addition, since the LED light source device 100 of the present embodiment is a modular design, the effect of facilitating replacement or maintenance is quickly achieved. That is to say, the outer diameters of the lamp housing 110, the first housing 120, the second housing 130, and the waterproof pad 140 are all the same, but only the inner dimensions of the second housing 130 and the waterproof pad 140 need to be illuminated according to different powers. The module 160 is sized and changed accordingly. The service personnel can replace the entire LED light source device 100 or only replace its internal components, as needed. Therefore, the LED light source device 100 of the present invention can easily replace the light-emitting modules or components of different powers in a modular manner, and has elasticity during replacement or maintenance.

Please refer to FIG. 8 and FIG. 9 together for a plan view and a cross-sectional view of a second preferred embodiment of the present invention. The difference between the embodiment and the foregoing embodiment is that the power of the light-emitting module 160 is different, and the shapes of the opening 132 and the through-hole 142 of the corresponding LED 164 are also different. In the present embodiment, the light-emitting diodes 164 of the light source group 160 are circular, and therefore the through holes 142 of the second casing 130 and the waterproof pad 140 are also circular. In addition, the light guide hem 134 is preferably a continuous loop and is attached to the inclined surface 150 to uniformly reflect the light of the light-emitting module 160, thereby increasing the illumination range of the light and the illumination efficiency of the light source.

As shown in FIG. 10 and FIG. 11 , a perspective view and a cross-sectional view of the LED light source device mounted on the outdoor light fixture are shown. The luminaire referred to herein preferably includes, but is not limited to, a street light 300. As shown in the figure, the street lamp 300 includes a plurality of heat dissipation fins 310 , a base 320 connecting the heat dissipation fins 310 , and a plurality of assembly holes 330 disposed in the base 320 .

Each of the assembly holes 330 of the street lamp 300 is preferably disposed corresponding to the assembly hole 112 of the partial lamp housing 110. A part of the fixing component 210 can be screwed onto the base 320 through the assembly hole of the lamp housing 110, thereby fixing the LED light source device 100. On the base 320 of the street light 300. The first housing 120 of the lamp housing 110 is also attached to the bottom surface of the lamp holder 320. Therefore, after the temperature equalization plate 102 absorbs the waste heat of the light-emitting module 160, the temperature-regulating plate 400 diffuses heat to the heat dissipation through the first housing 120. The fins 330 can achieve the effect of rapid heat dissipation.

When the maintenance personnel want to replace the light-emitting module 160 of different powers, the fixing device 210 is removed, and the LED light source device 100 can be removed. The maintenance personnel can perform necessary replacement or repair work on the components or the light-emitting module 160 in the LED light source device 100.
