Abstract

The utility model discloses an LED down lamp which comprises a radiator (11), a power panel (8), a diffusion plate (2), a light source plate (4), a front cover plate (1) and a rear cover plate (5), wherein the diffusion plate (2) is mounted on a front opening of the radiator(11); a front end seal ring (3) is arranged between the diffusion plate and the radiator; the diffusion plate (2) and the front end seal ring (3) are pressed by the front cover plate (1) and fixed on the front opening of the radiator (11); a power supply chamber and a connecting terminal chamber are arranged at the rear end of the radiator (11);the power panel (8) is fixed in the power supply chamber; the rear cover plate (5) is mounted at the rear end of the radiator (11) through an annular sealing gasket ring (7) to seal the power supply chamber and the connecting terminal chamber; a waterproof plug(10) is arranged on the side wall of the radiator (11); the waterproof plug is communicated with the connecting terminal chamber, so that the waterproof function and the function of being electrically connected with the outside world are achieved. According to the LED down lamp, as an integrated design is adopted, the entire lamp is compact in structure, aesthetic in appearance, easy to assemble, waterproof and moisture-proof.

Description

LED Down lamp

Technical field

The utility model relates to a kind of radiator and power pack integrated design and has the Novel LED down lamp of water-proof function, and particularly installation environment needs waterproof, small-power, small size, good looking appearance, the convenient LED Down lamp of installing.

Background technology

At present, now a lot of places are used LED Down lamp to throw light in a large number, and owing to being subject to the limit value of the conditions such as waterproof, heat radiation, size, existing most of LED Down lamps all can not meet the demands completely.Generally the radiator of Down lamp and power pack are designed separately, Down lamp fansink designs becomes bowl-shape, the inside is used for installing LED light source, the radiator back side is screwed a circle or rectangle power pack, line between power pack and light source board (being power output end) passes by the aperture of bowl-shape radiator bottom, and power panel 220V ac input end line stretches out by power pack side aperture.Adopt the LED Down lamp of this structural design, radiator is to separate independent installation with power pack, and installation process is complicated, not attractive in appearance in overall appearance, has also reduced the quality of light fixture.Contacting between light source and power supply must be passed through two power lines simultaneously, therefore must on power pack and radiator, punch, this just causes light source and power supply not to have good sealing property, can not waterproof, even can not dust protection, affect it in the application of a lot of occasions, particularly have the place of waterproof demand.

In addition light source and power pack are designed to one, light source and power supply are connected box body is inner, but the line of power panel input and outside 220V alternating current need to perforate on box body, still have the problem of sealing.

Utility model content

In order to realize radiator and power pack integrated design, and have the features such as water-proof function, compact conformation, outward appearance be beautiful, easy for installation, the utility model provides a kind of LED Down lamp.The technical solution of the utility model is: comprise radiator, power panel, diffuser plate, light source board, front shroud and back shroud, it is characterized in that: described diffuser plate is arranged in the open front of radiator, between its two, be provided with a forward end seal circle, diffuser plate and forward end seal circle are pressed abd fixed in the open front of radiator by described front shroud; Described light source board is fixed on the bottom of the bowl type light source chamber of radiator, in the rear end of radiator, is provided with a power supply room and terminal chamber, this two by a dividing plate, separated, and this two and described bowl type light source chamber between also with dividing plate, separate; Described power panel is fixed in power supply room, thereby and with a power supply cover closure, make can not touch each parts of power panel when pair of wire connection terminals operates; Described back shroud is arranged on the rear end of radiator to seal described power supply room and terminal chamber by circular seal packing ring; On the sidewall of radiator, be provided with a waterproof plug, it passes to terminal chamber the effect of playing water-tight and being electrically connected to the external world mutually.

The outside surrounding of described radiator is uniformly distributed radiator shutter, and its profile can design according to actual needs, blade quantity and highly also can adjusting according to radiating effect; Outer edge in its open front is also provided with several spring clips equably, plays Down lamp is fixed on to the effect on installation site.

The utility model adopts the beneficial effect of above technical scheme to be: adopt integrated design, the light source board of Down lamp and power panel are arranged in same housing, the waterproof plug of dependence housing front end diffuser plate and sealing ring, bottom power supply cover plate and sealing ring and side is realized the water-tight of whole housing, good water resistance be can reach, product application and performance boost are more conducive to; Rationally utilize enclosure interior space, in enclosure interior, carry out line, under the prerequisite that meets heat radiation requirement, reduce to greatest extent housing volume, therefore, whole modulated structure is compact simultaneously, and good looking appearance is easy to install; In addition, the unified waterproof plug that uses externally connects, and avoids impurity or steam to enter housing, has improved the working environment of lamp light source plate and power panel, thus the service life of having improved Down lamp.
