<p>A high-contrast waterproof surface-mounted LED lamp is provided, which includes: a casing provided with a reflector cup (10), a PCB (12) disposed on a lower surface of the casing, and an LED chip (1) and an optical guiding molding compound (4) disposed in the reflector cup (10). The casing is formed by laminating a lower light color layer (8) and an upper dark color layer (9). Black waterproof sealant (11) is provided on an upper surface of the PCB (12) and an outer surface of the light color layer (8) of the casing. In the present invention, an inner surface of the reflector cup (10) has a lower light color layer (8) and an upper dark color layer (9), which prevents the external light from affecting the luminance of the LED chip (1) and enhances the display contrast of the product. The black waterproof sealant (11) is provided to make the appearance of the casing all black, thereby maintaining the optimal effect of the luminance of the LED chip (1). Moreover, an effective waterproof effect is also obtained.</p> |
