Abstract
The invention relates to an LED (Light Emitting Diode) lamp, in particular to a lamp housing member in the LED lamp. In order to solve the following two problems that a cooling path is overlong and ambient light cannot be effectively taken out, the lamp housing member has the technical scheme that a chip is directly packed on a lamp housing, so that the cooling path of the chip is short; only through the chip, a binder and the cooling housing, the cooling effect of the chip is greatly improved; the cooling effect is guaranteed; and additionally, the ambient light of the chip can be effectively reflected, and the luminous flux of the LED lamp is increased.
Description
Technical field
The present invention relates to a kind of LED light fixture, particularly relate to the lamp housing member in a kind of LED light fixture.
Background technology
Be described as the 4th generation lighting engineering semiconductor lighting fast-developing, attract widespread attention, one has appearred at present to substitute the traditional lighting light fixture as agitation of target, the LED fluorescent tube is exactly one of them important representative.
The basic manufacturing process of LED fluorescent tube is at present: the led light source that first chip package is become certain form, then the led light source of some is fixed and is welded on the aluminium base with circuit, so again this aluminium base is fixed on the heat-dissipating casing with heat-conducting glue, an outstanding problem of the method is---the heat dissipation path of led light source is long, radiating effect is bad, cause the light decay of LED fluorescent tube serious, the lost of life.The someone has proposed to adopt the form of COB encapsulation to shorten the heat dissipation path of chip for this reason, such as 200910029883.8,201120026925.5, although the method has shortened the heat dissipation path of chip, but also only be to have reduced original holder part, the part heat dissipation path that keeps after improving is still longer, and they also need to be fixed on a certain thermal component by heat-conducting glue through the parts that COB encapsulates out; On the other hand and since they directly with chip package on aluminium base, cause the ambient light of chip effectively to take out, this also can cause the LED light fixture luminous flux loss that produces a lot, even might not reach specification requirement.
Summary of the invention
For solving above-mentioned two problems: the one, heat dissipation path is long, the 2nd, ambient light can't effectively take out, the invention provides a solution: with chip direct package on lamp housing, the heat dissipation path of chip is just very short like this, only have chip, binding agent and heat-dissipating casing, improved greatly the radiating effect of chip, and when guaranteeing radiating effect, also the light of guaranteed chip sides can effectively reflect, and promotes the luminous flux of LED light fixture.
Technical scheme of the present invention is:
A kind of LED lamp housing is characterized in that described lamp housing is the strip aluminium section bar, and the one side offers at least one part surface and is finished to reflectivity greater than 60% groove, and opposite side is extruded projection.Overall configuration when extruding by changing lamp housing, thus provide the foundation on lamp housing for the chip on-line equipment.The bossing of opposite side mainly is in order to increase the surface area of lamp housing, thereby is conducive to radiating effect.
As further improvement, described aluminium section bar is hollow structure.The consideration point that is set to hollow structure mainly is divided into two, and one is to be conducive to heat radiation, and another is the reasonable utilization that is conducive to the space.A part of light fixture member is placed in the hollow structure, has not only saved jockey, and provide the foundation for the various moulding of light fixture.
A kind of application as the open lamp housing of the present invention, the invention discloses a kind of LED light fixture, comprise chip, printed circuit board (PCB), lampshade, LED lamp housing, it is characterized in that: described chip is directly fixed in the groove of LED lamp housing, described printed circuit board (PCB) is directly fixed on the LED lamp housing, exists between described chip and the printed circuit board (PCB) to be electrically connected.
Further improvement as the open light fixture of the present invention also includes driving power, and described drive electric power unit is in hollow structure.Thereby not only saved the connection device between the members such as driving power and chip, and so that the overall aesthetics lifting of light fixture.
Further improve as of the present invention, described printed circuit board (PCB) also is fixed in the groove of LED lamp housing.Certainly can be placed in the same groove, also can be placed on respectively in two grooves.
As the preferred fixed form of printed circuit board (PCB), the invention discloses described printed circuit board (PCB) and chip and be fixed in two independent grooves.So, be separated between chip and the printed circuit board (PCB) and come, prevent that chip light emitting is absorbed, thereby the ambient light that more is conducive to chip is reflected, and play simultaneously the consumption of saving fluorescent material and reflection glue.
As preferably relating to of chip groove, the invention discloses described is mouthful little groove in the large end for the fixing groove of chip.Chip is fixed on less bottom, and the both sides of groove expand outwardly, and are conducive to the side reflection of light of chip, improve the luminous flux of LED light fixture.
In sum, adopt lamp housing disclosed in this invention and use the light fixture of this lamp housing, have perfect heat-dissipating, advantage that light efficiency is high.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing structure of the present invention and principle are described further.
The making of embodiment 1 lamp housing
To shown in the 3-3, lamp housing all has and is that strip aluminium section bar, one side offer at least one part surface and be finished to reflectivity greater than 60% groove 1 such as Fig. 1, Fig. 2 and Fig. 3-1, and opposite side is extruded projection.
Embodiment 1-1: referring to Fig. 1, the aluminium section bar with hollow structure, there is wave-shaped trench 4 at the back side, and there is a groove 5 in the front, and the cross section of groove 5 is trapezoidal, and inner surface is burnishing surface.
Embodiment 1-2: referring to Fig. 2, the aluminium section bar with hollow structure, there is the fin 6 of extruding at the back side, and the front has two grooves to be respectively 5-1,5-2, and the cross section of its further groove 5-2 is trapezoidal, and the cross section of groove 5-1 is rectangle.
Embodiment 1-3: to Fig. 3-3, be the aluminium section bar of non-hollow structure referring to Fig. 3-1, there is the fin 6 of extruding at its back side, and the front arranges respectively a groove shown in Fig. 3-2 and Fig. 3-3, two grooves perhaps is set shown in Fig. 3-1.
The assembling of embodiment 2 light fixtures
Referring to Fig. 4 and Fig. 5, the mode of two kinds of assemblings is disclosed in the present invention, a kind of be the light fixture that forms with the assembling of the lamp housing of hollow structure as shown in Figure 4; Another be the light fixture that forms without the assembling of the lamp housing of hollow structure as shown in Figure 5.All adopt in the present embodiment the lamp housing with two grooves 5, wherein cross section is the trapezoidal interior fixed chip 2 that is used for of groove 5-2, another cross section is the interior fixed printed circuit board 3 that is used for of the groove 5-1 of rectangle, and with gold thread or aluminum steel chip 2 is linked to each other with printed circuit board (PCB) 3, at last, lampshade 7 is installed below lamp housing, has been finished the overall package of light fixture.In the groove at chip 2 places, be coated with the mixture of fluorescent material and silica gel, above printed circuit board (PCB) 3 and fluorescent material and silica-gel mixture, be coated with transparent colloid, can obtain LED light fixture of the present invention.Owing to utilize the inclined-plane of groove 5-2 with isolated coming between chip 2 and the printed circuit board (PCB) 3, so printed circuit board (PCB) 3 can not produce absorption to the light that chip 2 sends, can save the consumption of fluorescent material and silica gel simultaneously.Simultaneously, chip 2 directly and lamp housing be fixed together, so heat dissipation path is dwindled good heat dissipation effect.
