Abstract

The utility mode discloses a high-power LED bulb lamp. The bulb lamp comprises a lamp socket, an insulation lamp holder, a heat dissipation cup body, a high-power LED, a mounting circuit board of thehigh-power LED, a lamp shade and a constant current driver, wherein the constant current driver is located in the insulation lamp holder, the heat dissipation cup body is fixed outside the insulationlamp holder in a detachable manner, the insulation lamp holder is fixed in the lamp socket in a detachable manner, the mounting circuit board is embedded in the circle center of the heat dissipation cup body, the lamp shade is mounted in an internal groove of the heat dissipation cup body, ring-shaped heat dissipation fins are arranged on the outer surface of the heat dissipation cup body, and a conducting wire connects the mounting circuit board of the LED with the constant current driver and is then led out of the lamp socket by the constant current driver. The utility model has the advantages that the radiating area of the heat dissipation cup body is enlarged to achieve the ultrathin and ultralight performances thereof, so that the weight of the LED bulb lamp is reduced for more convenient use and more reliable installation; the light degradation of the high-power LED is reduced, thereby prolonging the service life thereof and achieving the possibility of the production and application of the high-power LED bulb lamp; and the light distribution is more uniform, thereby achieving even and soft light color and better integral light-emitting effect.

Description

The great power LED bulb lamp

One, technical field:

The utility model relates to the LED lighting field, relates in particular to a kind of LED indoor lamp.

Two, background technology:

Existing bulb lamp mostly is conventional tungsten silk bulb lamp, and it is a thermal light source, not only lacks service life, also wastes electric energy, contaminated environment.Existing LED bulb lamp adopts low-power LED as light source more, and it does not have radiator, and in order to reach the needs of brightness, LED is densely distributed, and radiating effect is poor, and light decay is big, and the life-span is short.Existing LED bulb lamp also has minority to adopt great power LED, and its spreader surface is smooth, and area of dissipation is little, volume is big, Heavy Weight, and radiating effect is poor, the heat production height of great power LED, its heat can not in time distribute, and causes light decay big, life-span is shorter, adopts constant voltage to drive, and drives unstable, the long-term instability that causes light source of using, and the traditional lampshade of most of use cause luminous intensity distribution inhomogeneous, light efficiency is poor, can not get wide popularization and application.

Three, summary of the invention:

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of radiator volume little, and area of dissipation is big, and good heat dissipation effect drives stable great power LED bulb lamp.

For achieving the above object, technical solution of the present utility model is: a kind of great power LED bulb lamp, and it comprises installation wiring board, lampshade and the driver of socket, insulating lamp holder, heat radiation cup, single or a plurality of great power LED, great power LED; Driver is a constant-flow driver, and it is positioned at insulating lamp holder, and the heat radiation cup removably is fixed on outside the insulating lamp holder, and insulating lamp holder removably is fixed in the socket, and the center of circle that wiring board is embedded in the heat radiation cup is installed, and lampshade is installed in heat radiation cup inside groove; The outer surface of heat radiation cup has annular heat radiation wing; The installation wiring board of LED connects constant-flow driver by lead, and constant-flow driver is drawn lead outside socket.

Above-mentioned described installation wiring board of the present utility model is an aluminium base.

Above-mentioned described lampshade of the present utility model is contracted by nothing and becomes the PC material and make.

Above-mentioned described lampshade of the present utility model is a glass frosted lampshade, and its inner surface is uneven, and its diffuse reflection multi-angle refraction action makes luminous intensity distribution even, and photochromic evenly soft, the whole structure of bright dipping is better.

Because the design of the annular of heat radiation cup outer surface of the present utility model heat radiation wing, increased the area of dissipation of heat radiation cup, make the ultra-thin and ultralight of heat radiation cup, reduced the weight of LED bulb lamp, use more conveniently, install more reliably, and reduced the light decay of great power LED, prolonged its service life, made applying of great power LED bulb lamp become possibility.And glass frosted lampshade makes its luminous intensity distribution more even, and photochromic evenly soft, the whole structure of bright dipping is better.

Four, description of drawings

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

Fig. 1 is a front view of the present utility model;

Fig. 2 is a STRUCTURE DECOMPOSITION schematic diagram of the present utility model.

Five, the specific embodiment:

As depicted in figs. 1 and 2, present embodiment comprises screw thread socket 1, insulating lamp holder 4, heat radiation cup 2, single great power LED, the installation aluminium base 6 of great power LED, the rough glass frosted of inner surface lampshade 3 and constant-flow driver 5.Constant-flow driver 5 is positioned at insulating lamp holder 4, and heat radiation cup 2 screw threads are fixed on outside the insulating lamp holder 4, and insulating lamp holder 4 screw threads are fixed in the screw thread socket 1, and aluminium base 6 is embedded in the center of circle of heat radiation cup 2, and glass frosted lampshade 3 is installed in heat radiation cup 2 inside grooves.The outer surface of heat radiation cup 2 has annular heat radiation wing 7.The installation aluminium base 6 of LED connects constant-flow driver 5 by lead, and constant-flow driver 5 is drawn lead 8 outside screw thread socket 1.
