The LED Down lamp that throws light on

Technical field

The utility model relates to a kind of lighting, especially a kind of LED illumination Down lamp.

Background technology

In the life, people adopt incandescent lamp and electricity-saving lamp as traditional illuminating lamp, incandescent lamp and electricity-saving lamp need be connected 220V in working order the time and can cause self emitting light and heat, because the use amount of traditional lighting lamp is very big at present, so the today advocating environmental protection and energy saving, become a kind of huge waste to the energy.The traditional lighting lamp comprises lampshade, electricity-saving lamp or incandescent lamp, lamp socket and lamp bracket, offer an installing hole on the cover wall of lampshade, lamp socket is located at the installing hole place in the lampshade outside, and the lamp holder of electricity-saving lamp or incandescent lamp passes installing hole and lamp socket electrically connects, and lampshade and lamp frame of seat are located on the lamp bracket.The illuminating lamp of the type not only overall volume is big, and also has energy consumption height, deficiencies such as luminous efficiency is low, service life is short, anti seismic efficiency difference.

LED is as a kind of illuminating source, and lighting of LED postpones to have only for tens nanoseconds, can ignore; The reference color temperature of LED wide (1000-9000K), luminous intensity height (can up to 20000CMD); The domestic LED standard life-span, actual life was about 3-8 is ten thousand hours 6-10 ten thousand hours, and common electricity-saving lamp has only 8000 hours; The LED lamp is as cold light source, its luminous efficiency height, and the visible light luminous efficiency surpasses 95%; LED etc. do not have complicated combining structure and relative movement part, and earthquake-proof function is good; The LED lamp does not need the high voltage of 220V, only needs 6-24V to light.The LED lamp because of possess the above life-span long, energy consumption is low, caloric value is lower etc., and plurality of advantages is subjected to popular pursuing.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of environmental protection and energy saving, long LED illumination Down lamp of life-span.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED illuminating lamp, comprise lamp body and lampshade, it is characterized in that: described lamp body comprises circuit board and a plurality of LED fluorescent tube, the LED fluorescent tube is installed on the circuit board and with external circuit and electrically connects, circuit board is installed in lampshade and is conflicted fixing with the lampshade wall, end, circuit onboard led fluorescent tube place is towards the openend of lampshade, lampshade bottom offers the wire guide that passes for lead, place, lampshade upper conductor hole also is installed on the power supply adaptor of regulation voltage, power supply adaptor and circuit board electrically connect, power supply adaptor and external circuit conducting.Wherein, described LED fluorescent tube is rounded to be arranged on the circuit board, and the shape of circuit board and the cross section of lampshade are suitable, and the lampshade inwall is provided with the buckle of protrusion, offer on the board edge and the corresponding hole clipping of snapped-in position, circuit board and lampshade constitute snap fit and cooperate.

Adopt technique scheme, LED illumination cylinder lamp structure is simple, and luminous efficiency height, caloric value are all lower, in the brightness that reaches common 40-100 watt bulb, its power consumption have only three watts less than, so power consumption is extremely low, and the longlyest reached 6-10 ten thousand hours service life.And this LED illumination Down lamp range of exposures and irradiating angle all maximize, and the brightness that can reach is equivalent to the brightness of common 40-100 watt bulb.

Of the present utility modelly further be set to: place, described lampshade upper conductor hole also is installed on fin, fin comprises fin support and a plurality of heat sink body, fin support and heat sink body are tabular, a plurality of heat sink body are fixed perpendicular to parallel arrangement on the fin support and successively, and fin and power supply adaptor fit tightly mutually.Wherein, offer on the described fin and the suitable installing hole of power supply adaptor shape, installing hole inwall and power supply adaptor fit tightly, and fin and lampshade outer wall fit tightly.

Adopt technique scheme, fin can be by dispelling the heat with the heat transmission of power supply adaptor and lampshade, avoids LED illumination Down lamp internal cause heat accumulation and influence whole luminous efficiency and reduce its service life.

Of the present utility modelly further be set to: described lampshade also is provided with lamp bracket outward, and the lamp bracket surface convexes with the lamp bracket pin more than two or two, and the lamp bracket pin is fixedlyed connected with the lampshade outer wall respectively again.

Adopt technique scheme, made things convenient for the installation of this LED illumination Down lamp, as be hung on the fooled irradiation light of curtain, or be natural lamp source or the like in the film studio.

Below in conjunction with accompanying drawing the utility model is further described:
