Description

Ultra-thin LED down lamp

Technical field

The utility model relates to a kind of Commercial lighting, particularly relates to a kind of ultra-thin LED down lamp.

Background technology

Down lamp of the prior art adopts electricity-saving lamp and conventional tungsten silk bulb lamp as light emitting source more.Though electricity-saving lamp declares economize on electricity but its stability is poor, through it goes out light effect and will greatly weaken after a while, light decay is more serious.Electricity-saving lamp contains that infrared and ultraviolet, huge sum of money mercury, stroboscopic, high pressure, activated phosphor etc. are dangerous, energy consumption is large.Traditional tungsten filament bulb lamp life-span is short, conversion is low, first after the heat emission response time long, contain red radiation, the shortcoming such as frangible.

LED cylinder lamp structure of the prior art mainly fixedly is comprised of by a large amount of holding screws large-area reflection shield, led light source, cloche, vertical radiator, driving power and jacket etc.The led light source of this Down lamp is more concentrated, reflects by large reflector again, and rising angle is more limited, can have very large-area scope according to less than difficult situation.And the clear glass of this light fixture is fixed on light source top and directly contacts with metal shell, easily broken, its radiating effect is directly to conduct by radiator simultaneously, more single heat radiation and need area of dissipation larger, so that this light fixture weight is very heavy, and because it is vertically highly higher, need a large amount of auxiliary material, greatly increased the cost of construction and installation.Part and holding screw are than the multiple operation more complicated simultaneously, and production cost is high, is unfavorable for industrialization production.

Summary of the invention

Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides that a kind of structural design is more reasonable, the ultra-thin LED down lamp of good heat dissipation effect.

Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of ultra-thin LED down lamp, is characterized in: the thickness of described Down lamp is not more than 20mm, and it comprises PC cover, panel, spring, LED lamp pearl, aluminium base, washer, radiator and bonnet; The inner surface of PC cover scribbles phosphor powder layer, and PC cover and spring are located on the panel, and LED lamp pearl is fixed on the aluminium base, and aluminium base and washer all are fixed on the radiator; Aluminium base, washer and radiator all are located between panel and the bonnet, and panel and bonnet are locked by securing member, all spray the milky enamelled coating on panel and the bonnet; Described bonnet adopts aluminium sheet to be stamped to form; Be provided with the electric wire fairlead at bonnet.

In the ultra-thin LED down lamp technical scheme described in the utility model, further preferred technical scheme or technical characterictic are:

1, described electric wire fairlead is located at the middle part of bonnet, is provided with protective ring at the electric wire fairlead.

2, described PC cover is arc-shaped structure.

3, described LED lamp pearl is uniform sequential arrangement at aluminium base.

4, described radiator is provided with some fin that are the flower-shaped setting of radiation.

The utility model ultra-thin LED down lamp can be divided into according to structure and carries control device formula and control device separate type.The control device separate type adopts external power supply, can make light fixture more attractive in appearance, and guarantee the radiating effect of driving power.Adopting the another one benefit of external power supply is exactly maintenance and the repairing of being convenient to light fixture, when light fixture breaks down, and definite trouble unit that can be very fast.

Compared with prior art, the new cylinder lamp structure of this practicality is reasonable in design, and the inner surface dusting of PC cover is processed and improved its light extraction efficiency and uniformity, and spring can play good fixed installation effect.Set radiator is built-in, can realize good radiating effect.This Down lamp is easy for installation, and space requirement is little, adopts punching type aluminum bonnet, is not easy to damage, and adopts LED to do light emitting source, can be widely used in the illumination occasion of the high-grade industries such as assembly hall, market, supermarket, restaurant, show room.
