Abstract: Provided is a reflector for an LED lamp, including: a bottom portion having a first surface and a second surface opposite to each other, and a light hole formed to penetrate through the first surface and the second surface of the bottom portion. The first surface is mounted on a printed circuit board (PCB), so that a light source unit disposed on the PCB is located in the light hole and protrudes over the second surface, and a light emitting surface of the light source unit keeps a first distance from the second surface, and a vertical surface of a periphery of the light source unit keeps a second distance from a boundary between the second surface and the reflecting surface. A reflecting surface surrounds around the bottom portion and extends obliquely towards a direction away from the second surface, so that an angle is formed between the reflecting surface and the light emitting surface of the light source unit.

Abstract: Provided is a lamp with a drainage channel, including an outer case, a lamp module, and a rear cover. The lamp module includes a heat dissipation case having a mounting portion, and at least one light emitting elements and a reflector are sealingly mounted in the mounting portion. The heat dissipation case other than the mounting portion is provided with one drainage hole, and the lamp module is assembled at one end of the outer case so that water or liquid penetrated into the outer case, or water condensed in the outer case can be discharged through the drainage hole. The rear cover is pivotally coupled to the other end of the outer case to close or open the other end of the outer case so as to prevent the sensitive electronic components from being exposed to the outside and not to be adversely affected by environmental factors when repairing or changing the setting of the operation mode.
