The specific embodiment:

Below in conjunction with accompanying drawing this full mold is further described:

See Fig. 1,2,3, the utility model comprises: transparent lamp shade 1, housing 2, LED lamp panel 3, reflection shield 300, base 4, first sealing ring 6 and second sealing ring 8.

Lampshade 1 adopts stiffened flat plate glass to make, and it is installed in the upper surface of housing 2.

Housing 2 is a handware, its main body quadrate framework is formed with a flange 21 in the upper end of housing 2, this flange 21 is extended upward by the platform 22 of housing 2 upper ends and forms, so constitute the boss of a positive direction in the upper end of housing 2, this boss is just in time corresponding with shape, the size of lampshade 1.During installation, lampshade 1 is placed on this platform 22, and forms qualification by the side of 21 pairs of lampshades 1 of flange.In order to ensure sealing and fixing, adopt the bonding mode of glue between lampshade 1 and the housing 2.In order further to guarantee sealing, between lampshade 1 and platform 22, be provided with first sealing ring 6.Concrete structure is: first seal groove 221 that offers an annular along platform 22, first sealing ring 6 is placed in this

first seal groove

221,6 swellings of first sealing ring thoroughly seal the gap that may exist between lampshade 1 and the platform 22 under the pressure effect of lampshade 1.

Because lampshade 1 is installed by the outside, when whole light fixture is under water, under the pressure effect of water, lampshade 1 will further compress to platform 22, under this hydraulic pressure effect, combining between lampshade 1 and the platform 22 will be tightr, thereby guarantee the situation that can not occur leaking.

Housing 2 belows and base 4 are fixing.Base 4 is fixing with housing 2 bottom surfaces 23 by screw 7.Be formed with boss 25 in housing 2 inside, this boss 25 is established in order to offer screw just.Be provided with second sealing ring 8 between base 4 and the bottom surface 23.Its concrete structure is: offer second seal groove 231 on bottom surface 23, be placed with second sealing ring 8 of the sealing between a realization base 4 and the bottom surface 23 in this second seal groove 231.Under screw 7 screwing forces, second sealing ring 7 thoroughly seals the gap between base 4 and the housing bottom surface 23.

Described base 4 is a radiator, in order to increase area of dissipation, can be on base 4 the some radiator shutters 41 of moulding.

By said structure, the two ends up and down that lampshade 1 and base 4 are separately fixed at housing 2 form a confined space 5, and LED lamp panel 3 is positioned at this confined space 5.Housing 2 bottom surfaces are formed with a through hole 20, and the shape of LED lamp panel 3, big or small corresponding with this through hole 20 reveals by through hole 20LED lamp panel 3.

One reflection shield 300 is installed in

housing

2, and 300 one-tenth of this reflection shields are bowl-shape, and it has spotlight effect.

Described LED lamp panel 3 comprises the LED lamp 30 of several different colours, and each LED lamp 30 has the encapsulation of RGB three-colour light-emitting chip, and LED lamp 30 is realized the conversion of glow color by a control circuit 31.We know that RGB is three primary colors, and other color can be embodied by the stack of these three kinds of colors.The utility model is controlled the glow color of each LED lamp 30 just by control circuit 31, so just make whole LED lamp panel 3 send the light of setpoint color.

Offer a power input hole 24 in housing 2 one sides, be provided with waterproof case in these power input hole 24 places, power line enters in the housing 2 and with LED lamp panel 3 by waterproof case and is connected.

See Fig. 4, for the ease of connecting, the utility model can connect a support 9 on housing 2, and this support 9 adopts multi-angle keeper 26 with housing 2 junctions, fixes to realize the multi-angle between support 9 and the housing 2.Particularly, offer a plurality of locating slots on this keeper 26, support 9 two ends are articulated in this keeper 26 positions, and can realize the location of different angles by locating slot.Like this utility model just can be as required, select different angle, fixing in position or on the facility.

See Fig. 5, this is circuit theory diagrams of the present utility model, after the foreign current input, at first passes through AC-DC conversion, alternating current is converted to direct current, pass through transformation then, its voltage is reduced, pass through rectifying and wave-filtering then or export the LED lamp panel to, cross pulse-width controlled simultaneously, through optically-coupled, connect light-adjusting module, realize adjusting to bright and dark light.

See Fig. 6, this is the circuit theory diagrams that the utility model changes light color, controls the glow color of LED lamp by the photochromic color processor of setting, thereby makes whole lamp panel show the color of appointment.

Certainly, the above only is embodiment of the present utility model, be not to limit the utility model scope, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
