Abstract
The utility model belongs to the semi-conductive lighting field, and particularly relates to a light emitting diode (LED) lighting fixture. The LED lighting fixture comprises a lamp head, a lamp shell and a lamp cover. An aluminum base is arranged inside the lamp shell. A plurality of LED chips emitting yellow light and a plurality of LED chips emitting white light are fixed on the aluminum base. LED chip base pins are connected with a power supply through a guide wire. The LED chips emitting the yellow light and the LED chips emitting the white light on the aluminum base are evenly distributed along the center of the aluminum base, and are arranged at intervals. The inner surface of the lamp cover is coated with emulsion powder. According to the LED lighting fixture, the LED chips emitting the yellow light and the LED chips emitting the white light are arranged in terms of a certain style, and the lamp cover is coated with the emulsion powder. Therefore, the LED lighting fixture can emit pure warm white light, and overcomes the defect that the prior LED chip emitting the warm white light is not pure in brightness; and production cost is greatly reduced.
Description
Technical field
The utility model belongs to field of semiconductor illumination, relates in particular to a kind of LED lighting.
Background technology
Along with the continuous ripe development of semiconductor technology, the LED fluorescent tube progressively replaces the first-selection that incandescent lamp becomes the household illuminating lamp source.Family's LED lamp commonly used is mainly amber light or positive white lamps now, though the amber light tone is relatively gentleer, as illumination, brightness is not enough; And positive white lamps light intensity is stronger, and brightness is bigger, and is more dazzling.The warm white lamp is because light intensity is moderate, and brightness is suitable, more is prone to accepted by people.But the led chip brightness of launching warm white light on the market is impure, does not meet production requirement, and the led chip of emission warm white light is more expensive compared to the yellow led chip price with positive white of emission, and production cost is higher.
The utility model content
The utility model technical problem to be solved is to provide a kind of can send pure warm white light and the low LED lighting of production cost.
The purpose of the utility model mainly is achieved through following proposal: a kind of LED lighting; Comprise lamp holder, lamp housing and lampshade; Be provided with aluminium base in the said lamp housing; Be fixed with the led chip of a plurality of emission gold-tinteds and the led chip of a plurality of emission white lights on the said aluminium base, said led chip pin is through wire connecting power, and the led chip of emission gold-tinted evenly distributes along the aluminium base center with the led chip of emission white light on the said aluminium base; And two kinds of led chips are provided with at interval, and said lampshade inner surface scribbles latex powder.
In this programme; The led chip of emission gold-tinted and the led chip of emission white light evenly are installed, and two kinds of led chips are provided with at interval on aluminium base, simultaneously at lampshade inner surface coated with latex powder; Such two kinds of led chips are after energized; Gold-tinted and white light mix, and see through lampshade then, and that sends is warm white light.Therefore; Need not launch the led chip of warm white light; The led chip that only need will launch gold-tinted and white light is added the effect of latex powder on the lampshade by certain arrangement mode; Can send pure warm white light, overcome the impure shortcoming of led chip brightness of existing emission warm white light, and greatly reduced production cost.
As preferably, the led chip of said emission gold-tinted is circle distribution with the led chip of emission white light along the aluminium base center.Two kinds of different chips are circle distribution, gold-tinted and white light are fully mixed, and profile are more attractive in appearance.
As preferably, described aluminium base bottom is provided with the heat conduction silicon chip, and the size and the aluminium base of described heat conduction silicon chip are complementary.Be provided with the heat conduction silicon chip makes and the utlity model has better radiating effect in the aluminium base bottom.
As preferably, described aluminium base and heat conduction silicon chip are circle.
Therefore; The beneficial effect of the utility model is: the effect of adding latex powder on the lampshade through the led chip of emission gold-tinted and white light by certain arrangement mode; Can send pure warm white light; Overcome the impure shortcoming of led chip brightness of existing emission warm white light, and reduced production costs greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Illustrate: 1-lamp holder, 2-lamp housing, 3-lampshade, 4 aluminium bases, 5-heat conduction silicon chip, the led chip of 6-emission gold-tinted, the led chip of 7-emission white light.
The specific embodiment
A kind of LED lighting comprises lamp holder 1, lamp housing 2 and lampshade 3, is provided with circular aluminium base 4 in the said lamp housing 2, the heat conduction silicon chip 5 that the aluminium base bottom is provided with is circular, size and aluminium base are complementary.Be fixed with the led chip 6 of 2 emission gold-tinteds and the led chip 7 of 2 emission white lights on the said aluminium base 4; The led chip 6 of emission gold-tinted is circle distribution with the led chip 7 of emission white light along the aluminium base center equably; Two kinds of led chips are provided with at interval; Led chip pin on the said aluminium base is through wire connecting power, and said lampshade 3 inner surfaces scribble latex powder.
The led chip 6 of emission gold-tinted and the led chip 7 of emission white light evenly are installed on aluminium base; And two kinds of led chips are provided with at interval; At lampshade 3 inner surface coated with latex powder, such two kinds of led chips are after energized simultaneously, and gold-tinted and white light mix; See through lampshade 3 then, that sends is warm white light.Therefore; Need not launch the led chip of warm white light; The led chip that only need will launch gold-tinted and white light is added the effect of latex powder on the lampshade 3 by certain arrangement mode; Can send pure warm white light, overcome the impure shortcoming of led chip brightness of existing emission warm white light, and greatly reduced production cost.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should understand in addition; After the content of having read the utility model instruction; Those skilled in the art can do various changes or modification with the number and the spread geometry of the led chip of emission white light to the led chip of emission gold-tinted on the aluminium base in the utility model, and these equivalent form of values fall within the application's appended claims institute restricted portion equally.
