Abstract

An upper shell used for an LED lamp is divided into an upper portion and a lower portion, wherein the cross section of the lower portion is larger than that of the upper portion, the upper portion is connected with a lamp cap of the LED lamp, the lower portion and a lower shell of the LED lamp are connected to form a cavity for containing LED chips, and a plurality of strip-shaped radiating slots are arranged on a body of the upper shell. Radiation of the LED lamp is obviously optimized by the aid of wind tunnel radiating effect formed by the strip-shaped radiating slots of the upper shell and other components of the LED lamp, and the integrated level of the LED lamp can be apparently improved on condition of the same luminosity. Accordingly, the upper shell used for the LED lamp has the advantages of high radiating efficiency, small size, energy economization and long service life and the like.

Description

A kind of upper casing that is used for the LED lamp

Technical field

The utility model relates to the shell that uses in the lighting source of a kind of integrated use LED, specifically, relates to a kind of upper casing of the LED of being used for lamp.

Background technology

LED has advantages such as luminous efficiency height, life-span length and power saving, has been subjected to paying close attention to widely in the normal lighting light source field.Because single led luminous quantity is limited, generally, need integrated a plurality of LED as lighting source.

But after increasing LED quantity, also can cause heat dissipation capacity to increase, the user mode and the life-span of light fixture are caused negative effect.In the lighting of present integrated use LED, radiating effect is generally not good.Therefore in order to reduce the hot polymerization collection, the interval between each LED is bigger, and this moment, the integrated level (the LED lamp quantity that promptly is provided with in unit are/volume) of LED lamp reduced, thereby has caused overall lamp specifically long-pending bigger.

In addition, the LED lamp generally is made up of a plurality of LED (generally being positioned on the LED paster) and the heat abstractor that are positioned at outside housing (generally comprising upper casing and lower casing), are contained in this housing.Each several part all produces material impact to the heat dispersion of LED lamp.Yet the upper casing ubiquity of LED lamp influences the defective of internal heat dissipating at present.

The utility model content

In order to overcome the above-mentioned shortcoming and defect of prior art, the purpose of this utility model is to provide a kind of upper casing of the LED of being used for lamp.

The upper casing that the utility model is used for the LED lamp is divided into the upper and lower, the cross section of its middle and lower part is greater than the cross section on top, described top is connected with the lamp holder of LED lamp, the lower casing of described bottom and LED lamp is connected and forms the inner space that holds the LED paster, has a plurality of bar shaped louvres on the housing of this upper casing.

Preferred as technique scheme, described bar shaped louvre has identical curved shape.

Preferred as technique scheme, the quantity of described bar shaped louvre is 4-8.

Preferred as technique scheme, the cross section of described upper and lower is circle.

Preferred as technique scheme adopted buckle or is threaded between the lower casing of described bottom and LED lamp.

Preferred as technique scheme also held heat abstractor in the described upper casing.

Preferred as technique scheme also held electronic transformer in the described upper casing.

The utility model is used for the upper casing of LED lamp, and the wind-tunnel cooling effect that a plurality of bar shaped louvres by upper casing and the miscellaneous part of LED lamp form has been optimized the heat dispersion of LED lamp significantly.Under the situation of equal brightness, can significantly improve the integrated level of LED lamp.Therefore, have advantages such as rate of heat dissipation height, volume are little, energy-conservation, long service life.

Description of drawings

Fig. 1 is the structure chart of the upper casing of the utility model one embodiment;

Fig. 2 has been to use the structure chart of the LED lamp of the utility model upper casing.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.

Shown in Figure 1 is the structure chart of the upper casing of the utility model one embodiment.This upper casing 1 is divided into top 11 and bottom 12, and the cross section of its middle and lower part 12 is greater than the cross section on top 11.Structures such as that the cross section of top 11 and/or bottom 12 can have is square, polygon, circle.The cross section of preferred top 11 and bottom 12 is circle, forms the structure that is similar to ordinary incandescent lamp.

The lamp holder 2 of top 11 and LED lamp is connected (as shown in Figure 2), and the lower casing 3 of bottom 12 and LED lamp is connected and forms the inner space that holds LED paster 4.Can adopt buckle as shown in Figure 2 to connect between the lower casing 3 of bottom 11 and LED lamp, also can adopt to be threaded, the utility model is not limited to this.

Have a plurality of bar shaped louvres 13 on the housing of upper casing 1, the quantity of bar shaped louvre 13 is preferably 4-8, is shown as 6 in the embodiment shown in fig. 1.Bar shaped louvre 13 can have identical curved shape as shown in Figure 1.

By using upper casing 1 of the present utility model, can form LED lamp as shown in Figure 2.In this LED lamp,, also hold heat abstractor 5 in the upper casing 1 in order further to strengthen radiating efficiency.In addition, can also be in this LED lamp built-in electronic transformer 6, this electronic transformer 6 also is housed inside in the upper casing 1.

In sum, the utility model is used for the upper casing of LED lamp, and the wind-tunnel cooling effect that a plurality of bar shaped louvres by upper casing and the miscellaneous part of LED lamp form has been optimized the heat dispersion of LED lamp significantly.Under the situation of equal brightness, can significantly improve the integrated level of LED lamp.Therefore, have advantages such as rate of heat dissipation height, volume are little, energy-conservation, long service life.

Therefore, the beneficial effects of the utility model are conspicuous.

It should also be understood that; though the utility model clearly demonstrates by above embodiment and accompanying drawing thereof; yet under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding variations and correction according to the utility model, but these corresponding variations and correction all should belong to the protection domain of claim of the present utility model.
