Description

A kind of socket type LED illuminating lamp

Affiliated technical field

The invention of this reality relates to a kind of LED lighting, is particularly useful for the socket light fixture of room lighting.

Background technology

The LED lighting device has the characteristics such as energy-conservation, long-lived, meets the requirement of national encourage growth green illumination, low-carbon (LC) society, and its product has good market prospects.The socket type illuminating lamp is the main developing direction of China's LED light fixture as the form of China's main indoor illuminating lamp.Yet because the LED lamp needs special cooling measure, because the amount of heat that LED lamp pearl produces when luminous affects its life-span and light efficiency, the LED lighting must have good heat dissipation design to avoid.The lamp body structure of most socket type LED lamp is all unreasonable, all do not take cooling measure such as patent 201110101645.0, patent 201010126994.3, patent 200720057162.4 related socket type LED lamps, do not take the LED lantern festival of cooling measure to make luminous efficiency fast-descending or even corrupted because of the heat that the LED tube core produces when luminous; What patent 201010151656.5, patent 201110238441.1 related socket LED lamps provided is between above socket and the lamp body method that the radiation aluminium alloy components dispels the heat to be set, this method good heat dissipation effect, but complex structure and outward appearance and traditional socket bulb fall far short, using is not easily, and the radiation aluminium member has also increased cost simultaneously; The radiator structure of the LED lighting that patent 200610078913.0 is related is the polygonal column supporting structure that adopts several rectangle sides, LED lamp pearl is installed in supports the alar part that makes up, supports to make up material with the good copper alloy made of thermal conductivity.The good heat dissipation effect of this method, but also exist complex structure and outward appearance and traditional socket bulb to fall far short, make inconvenience, problem that cost is high.Because the radiator structure of socket type LED lamp can not well solve, the development at home of socket type LED lamp lags behind the LED fluorescent lamp far away.

Summary of the invention

For solving socket type LED light fixture heat dissipation problem.The present invention has provided the socket type LED illuminating lamp of a kind of LED of employing lamp bar assembling, and this lamp adopts the LED lamp bar with heat sinking function, and the heat that can effectively LED lamp pearl be produced scatters, and makes the socket type LED illuminating lamp can be because of the problems affect life-span of generating heat.Close on this socket type LED illuminating lamp and the traditional bayonet lamp cap lamps structure, and simple in structure, cost is very low, is fit to promote the use of.

A kind of socket type LED illuminating lamp that adopts the assembling of LED lamp bar of the present invention comprises several LED lamp bars 3, LED lamp pearl driving power circuit plate 4, shell 2 and socket 1.Several LED lamp bars 3 are installed on the LED lamp pearl driving power circuit plate 4; LED lamp pearl driving power circuit plate 4 links to each other with socket 1 by power supply lead wire; shell 2 is designed with hole to be passed through by LED lamp bar; shell 2 wraps to protect LED lamp pearl driving power circuit plate 4 with LED lamp pearl driving power circuit plate 4, and shell 2 is fastenedly connected to form an integral body with socket 1.

LED lamp bar 3 is installed several LED lamp pearls, the required light source of the luminous generation of LED lamp pearl.Constituting of it: some the LED lamp pearls that are electrically connected in a certain way are installed on the aluminium base; aluminium base mounted LED lamp bulb side covers light transmissive material in order to protect LED lamp pearl and diffusing light, is designed with the mounting disc that cooperates with LED lamp pearl driving power circuit plate 4 on the aluminium base conveniently to be fixedly connected with.Aluminium base as main radiator structure, is gone out the dissipation of heat that LED lamp pearl produces simultaneously, aluminium base also available pcb board also or ceramic substrate substitute.

LED lamp pearl driving power circuit plate 4 is circuit boards, and circuit board realizes the 220V alternating current is converted to constant voltage, the constant-current supply of energy driving LED lamp pearl, is designed with the hole seat and the electrical connection arrangement that are used for fixing and are electrically connected LED lamp bar on the plate.

LED lamp bar number increases and decreases according to power requirement, and the lamp number is more, and luminous light intensity is larger, and power is also larger.
