Description

The LED Lamp cup

Technical field

The utility model relates to a kind of LED light fixture, especially a kind of LED Lamp cup of alternative halogen lamp Lamp cup.

Background technology

Along with succeeding in developing of high-power and high-luminance LED chip and improving constantly of luminous efficiency thereof, increasing great power LED begins to enter lighting field in recent years.LED reaches 120 lumens for every watt, and common halogen lamp has only 15～18 lumens, 8W LED Lamp cup just can substitute 50W halogen lamp Lamp cup, only need the power consumption of common halogen lamp 15%, adopt high-powered LED lamp to replace halogen lamp, low, the obvious energy conservation that not only consumes energy, and long service life are to replace first choice of the halogen lamp.When being used for having the halogen lamp light fixture now, be subjected to the restriction of existing halogen lamp light fixture, require the Lamp cup volume little, highly low with the alternative halogen lamp cup of the LED Lamp cup that sends equal brightness.But, caloric value is big during great power LED work, the heat that produces as can not be in time with chip operation the time sheds, along with temperature raises, the crash rate of LED can increase greatly, and light decay can aggravate, the life-span also can shorten, so heat dissipation design is an important step in the design of LED fitting structure, under little, the highly low situation of Lamp cup volume, the big especially problem of dispelling the heat.The heat dissipation design of LED light fixture normally closely cooperates LED lamp substrate and radiator at present, and the heat that led chip is produced is delivered to radiator by substrate, and radiator distributes heat again; Or adopt radiator fan blowing radiator or LED lamp substrate, wish the heat that gathers on radiator or the substrate is distributed.But owing to the restriction of volume and height, air-flow is subjected to stopping of radiator or substrate on Lamp cup is used, and gas channel is not smooth, can not fast heat be taken away, and radiating effect is poor, and heat localization is difficult to eliminate; Above-mentioned several mode, for the little and compact high-power Lamp cup of volume, radiating effect is to be beyond one's reach, and realize that the LED Lamp cup substitutes the halogen lamp cup and is used for existing halogen lamp light fixture, and volume structure and product reliability problem have become a technical bottleneck that influences the extensive use of LED Lamp cup.

The utility model content

The utility model aims to provide and a kind ofly can solve volume structure and product reliability problem well, and can directly substitute the LED Lamp cup that the halogen lamp cup is used for existing halogen lamp light fixture, and it is simple in structure, volume is little, and is in light weight, and cost is low, good heat dissipation effect, long service life.

The purpose of this utility model is achieved in that described Lamp cup housing is a metal shell, and Lamp cup housing inner chamber is provided with retainer ring, and retainer ring is provided with the hole; The lamp plate that LED is housed places Lamp cup housing top inner chamber, links to each other with the upper surface of retainer ring, and radiator fan places Lamp cup lower housing portion inner chamber, links to each other with the lower surface of retainer ring, and lamp plate and radiator fan are fastened on the retainer ring with screw; The Lamp cup housing bottom links to each other with Lighthead assembly; Lamp plate and Lighthead assembly that LED is housed are equipped with louvre or groove.

The retainer ring of described Lamp cup housing inner chamber setting changes fixing lug boss or fixed leg into.

On the described LED optical lens is installed, Lamp cup housing top or optical lens are provided with louvre or air gap.

On the described Lamp cup housing reflector is installed.

Be placed with electronic devices and components in the inner chamber of described Lighthead assembly.

Advantage of the present utility model is: 1, the Lamp cup shell structure is simple and when sending equal brightness, and the LED Lamp cup can satisfy the matching requirements that have the halogen lamp light fixture now.2, the inside of Lamp cup is furnished with fan, and the LED lamp plate is provided with louvre or groove, and under little, the highly low situation of Lamp cup volume, the air-flow that fan produces can penetrate the LED lamp plate, rapidly heat is taken away, and avoids forming heat localization.3, Lamp cup adopts metal shell to play thermolysis, good heat dissipation effect simultaneously.4, succinct, easy to process, practical, the low cost of manufacture of profile, price function are than high.5, can directly substitute the halogen lamp Lamp cup, energy-saving effect is remarkable, economic benefit is obvious, product reliability is high, be convenient to large-scale popularization uses.
