Abstract

The utility model provides a high-power LED (light-emitting diode) lamp structure which is a simple LED lamp structure, and an LED illuminating device with the structure has the properties of both high power and favorable heat radiation. The high-power LED lamp structure can overcome the defect that when an AC/DC (alternating-current/direct-current) converter is arranged on a direct-current LED (DC/LED) lamp, the volume of a system is large, and can solve the problems such as the temperature of lamp balls is high because a great number of chips and assemblies of an ACLED (alternating-current LED) are integrated and packaged in the lamp balls in a small region.

Description

A kind of high-power LED lamp structure

Technical field

The utility model relates to lighting device, is specifically related to a kind of high-power LED lamp structure, belongs to International Classification of Patents F21 technical field.

Background technology

Make a general survey of the circuit structure of light emitting diode in the prior art (LED) lamp; Mainly be divided into two types: the first kind is for using galvanic light emitting diode (DC LED), and DC LED system causes system bulk bigger because of using the AC/DC converter; Also increase cost simultaneously, shortened service life.Second type is use alternating current of led (AC LED), and alternating current of led need not use the AC/DC converter, exempts the restriction of AC/DC converter volume, but AC LED integrates crystal grain and functional unit and be packaged in the lamp pearl.Shown in the U.S. Patent application (patent No. 6,957,899) of the Taiwan patent application (notification number I257185) of Fig. 1 of Figure of description, Fig. 2.The design of its primary structure that adopts, the micromeritics light emitting diode polyphone that comprises two reversed polarities is at least formed, and it is luminous in turn to be attached under the situation that applies alternating current each micromeritics each other.Yet the greatest problem in should technology does; A large amount of chips and functional unit are concentrated and are packaged in the lamp pearl of a zonule; Cause temperature drift, make electric current and voltage (V-I) characteristic curve of light emitting diode, in lighting process, produce shift phenomenon; Because of operand power rises, cause problems such as luminance nonuniformity or light emitting diode burn easily.Therefore also can't in single lamp pearl, add high-power.

Summary of the invention

The purpose of the utility model is to provide a kind of high-power LED modulated structure, and a kind of simple circuit configuration promptly is provided, and makes this light emitting diode illuminating apparatus have the high-power characteristic good with heat radiation concurrently.

The purpose of the utility model realizes through following technical scheme.

A kind of high-power LED lamp structure, it includes: a shell; One heat radiation bearing substrate; One through external ac power source power supply and convert thereof into the bridge rectifier of dc source; At least one group of luminous group; This luminous group is made up of the luminescence unit polyphone of an above identical polar direction; This luminescence unit is according to adjustment internal resistance of voltage matches demand and luminescence unit quantity; When the LED light fixture has more than two groups luminous group, between luminous group, be connected in bridge rectification power with the parallel way of identical polar direction; Revise assembly for one, this correction assembly and luminous group are connected in parallel.On the heat radiation bearing substrate bridge rectifier, luminescence unit, correction assembly and power input terminal can be installed.

Being shaped as of said heat radiation bearing substrate is square or circular.

Described shell includes diffuser, camera lens and containment vessel.

Described luminescence unit includes at least one light emitting diode.

Described luminescence unit includes at least one light emitting diode and at least one resistance.

Described correction assembly is electric capacity or resistance.

The utility model has solved direct current light emitting diode (DC LED) lamp; Because of using the AC/DC converter; Cause system bulk bigger, and alternating current of led (AC LED) is because of chips and assembly are concentrated problems such as causing lamp pearl temperature drift in the lamp pearl that is packaged in a zonule in a large number.
