Description
Technical field
The utility model relates to a kind of straight-down negative lighting, and a kind of LED Ceiling light specifically is provided.
Background technology
In 21 century energy deflation strategy, energy-saving and emission-reduction are the primary measure of countries in the world always.And using advanced LED lighting to replace unique trend that traditional hot vehement light source is the illumination revolution according to the field.In the Ceiling light field with embedded mounting means, to existing popular compact fluorescent lamp (electricity-saving lamp), saved more than 60% by energy resource consumption from the incandescent lamp before last century for its light source.Because electricity-saving lamp is the physics emission type that adopts glass lamp, causes its volume bigger, particularly along with the increase of self power, the proportional example of volume increases.Require the occasion of setting height(from bottom) at some, electricity-saving lamp has been subjected to unprecedented challenge in the application of recessed light fixture.And the rise in LED solid luminescent source is undoubtedly the another seat important milestone of lighting field, the LED light emitting source has been overturned the single Glass lamp tubular type ray structure of traditional energy-saving lamp, can be installed on the light fixture with a kind of type or the illumination mode of face type, and can make up by many luminescent devices, make the light fixture volume further dwindle and attenuate, particularly LED Ying Yong Yu Clamp-on goes into the Ceiling light neck that formula is installed, significantly attenuate light fixture thickness.Use the side-light type Ceiling light of led light source, and gross thickness even can be less than 10MM.
Also having occurred part on the existing market is the Ceiling light of light source with LED, but the imitated traditional Ceiling light moulding of festive lantern these days, shell mechanism is unreasonable, does not have effective and integrative heat radiation theory, and radiating effect is poor; Led light source is selected not match, and causes lighting angle less than normal, is not suitable for floodlighting; The light of dazzling of light emitting source is handled undesirablely, and human visual is uncomfortable, uses for a long time even might cause eyesight to be affected.Though go into formula Ceiling light field at Clamp-on, led light source is a development in future trend, how to go to avoid the problems referred to above in actual applications, and we press for and develop a kind of brand-new embedded LED Ceiling light that is suitable for led light source that really closes.
The utility model content
The utility model patent technical problem to be solved be at the problems referred to above provide that a kind of radiating effect is very good, volume is light and handy, be applicable to embedded mounted LEDs Ceiling light.
The utility model patent solves the problems of the technologies described above the technological means that is adopted: this LED Ceiling light, comprise lamp housing, be provided with in the lamp housing can fixed L ED light source circuit board, it is characterized in that: described circuit board is a flexible printed circuit board, described led light source is the patch-type led light source, the patch-type led light source directly is welded on the flexible printed circuit board, thereby make patch-type led light source and flexible printed circuit board form the LED illuminating module jointly, described led light source module is installed in the described lamp housing by heat-conducting glue, and be the round setting, it is integral piece that described lamp housing adopts aluminium die casting one-shot forming, and vertically be distributed with fin on the lamp housing outer wall, the lamp housing outer surface is provided with the baking vanish layer simultaneously, and lamp housing is provided with loophole.Like this, housing has mechanical performance and lighter weight preferably, and same aluminium alloy has good thermal conductivity factor, guarantee for led light source provides good heat radiation, and the surperficial baking vanish of shell can make the light fixture outward appearance more attractive in appearance, corrosion-resistant.The lamp housing of use die-cast aluminum alloy material is light, durable, chemical stability is good, particularly highly beneficial to the LED heat radiation, this technology has solved the fitting structure of LED Ceiling light, the integration of heat radiation fully, the final led light source temperature that guarantees is controlled at zone of reasonableness, has effectively guaranteed the whole lamp life-span.Flexible PCB is a kind ofly to have a high reliability with what PET or PI film were that base material is made, good flexible printed circuit insulate, this FPC has the characteristics of distribution density height, in light weight, thin thickness, the LED illuminating module is close to the lamp housing inboard, the heat that is produced when led light source is luminous like this can conduct to metal shell fast, and finally be emitted in the air by cross-ventilation, the fin of lamp housing can be eliminated problems such as the luminous power decline that causes light source because of LED is overheated, colour temperature drift, light decay.
As improvement, be provided with the LGP that is positioned at LED illuminating module inboard in the described lamp housing; LGP uses the PMMA sheet material of optical grade, LGP surface is printed on density, reflective spot not of uniform size with the screen printing technology, when light passes through leaded light source internal transmission, reflective spot can be converted into vertical light with irreflexive form with directional light and penetrate from LGP is positive, by various densitys, reflective spot not of uniform size are set at bottom surface of light guide plate, can make the LGP bright dipping even.The PMMA sheet material of optical grade is generally Transparent color, and light transmittance is up to more than 92%, and has mechanical strength preferably.LGP is converted into vertical light with the directional light of lateral emitting, thereby effectively lamp thickness is put in order in control, again in conjunction with the light DIFFUSION TREATMENT in later stage, eliminates light fixture fully and dazzles light.
Improve, be connected with bonnet on the described lamp housing, this bonnet scribbles reflective printing ink or posts reflective sheeting towards the one side of LGP, and the surface of bonnet also is provided with the baking vanish layer; In can light leak reflected back LGP, be used for improving light extraction efficiency with bottom surface of light guide plate.Two bayonet sockets have been designed on aluminium alloy bonnet both sides, are used for fixing the torsion spring of Ceiling light, when embedded installation, this torsion spring with himself mechanical elasticity with light fixture " embedding " on the ceiling that is mounted, torsion spring adopts stainless steel, electroplating processes is done on the surface.Cap surface has also carried out the baking vanish processing behind this aluminium alloy, is used to prevent self from being corroded.The aluminium alloy bonnet is connected with the screw mode with the described heat-dissipating casing in front, also is used for fixing LGP simultaneously.
Improve again, be provided with light diffusing sheet in LGP exiting surface the place ahead, light diffusing sheet adopts light diffusion PC or PMMA material, can will handle again evenly from the light that LGP penetrates, light diffusing sheet is as the final exiting surface of light fixture, make LED Ceiling light surface light emitting even, effectively eliminate and dazzle light, make human body obtain comfortable visual effect.
Compared with prior art, the advantage of the utility model patent is:
1, the lamp housing outer surface of the utility model patent is provided with fin, and uses aluminium alloy one piece casting forming, good heat dispersion performance;
2, the led light source of the utility model patent uses flexible PCB to be welded to form the annular light source module, and light source module side is beneficial to the led light source heat radiation in the lamp body structure inboard;
