Description
Technical field
The utility model relates to a kind of lighting, specifically is a kind of with the LED light fixture with excellent heat dispersion performance of large-power light-emitting diodes as lighting source.
Background technology
Along with the progress of technology, led light source is with advantage such as its energy-saving and environmental protection, longevity in many more places that produce that are applied to living more muchly.
The major issue that the LED light fixture need solve when design is heat radiation.Led chip can send very big heat when work, if these heats in time can not be distributed, cause that the LED temperature is too high, just can influence luminous efficiency, the service life of led chip, even cause the damage of light fixture.
The utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of LED light fixture with excellent heat dispersion performance, makes it to possess good performance of heat dissipation, guarantees the light fixture reliably working.
For this reason, the utility model is by the following technical solutions:
LED light fixture with excellent heat dispersion performance, comprise LED lamp holder and driving power, it is characterized in that: described lamp holder has disc lamp holder radiator, the central authorities of lamp holder radiator offer the led chip container cavity, be packaged with led chip in the container cavity, be coated with lens on the container cavity, described lamp holder radiator comprises some strip fins from the outside radial extension of disc centre, described driving power is located in the heat radiation power pack that is separated with lamp holder, power pack is covered with radiating fin outward, and power pack links to each other by two joint pins with lamp holder.
Led light source is positioned at isolated different cavitys with driving power, and heat distributes respectively, and radiating effect is better.Even the heat that the strip fin of outside radial extension can produce chip effectively distributes, reduce the chip operation temperature.
As to the improving and replenishing of technique scheme, the utility model is further taked any combination of following technical measures or these measures:
Strip fin on the described lamp holder radiator comprises the main rectangular fin that is cross distribution and the auxiliary rectangular fin between main rectangular fin, main rectangular fin is positioned at inboard root and has installing hole, and a pressure ring is connected by connector lens are fixed on the lamp holder radiator.
Strip fin on the described lamp holder radiator comprises the furcation that is positioned at inboard root and is positioned at the outside, and each strip fin is divided into two fin forks and stretches out in furcation.
Be installed with lead-in wire in the described joint pin, lead-in wire is electrically connected driving power with led chip.
Described power pack is provided with the U type fixed support of adjustable-angle.
The beneficial effects of the utility model: this light fixture is easy to process, and good heat dissipation effect is easy to use, and functional reliability and stability are high.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model;
Fig. 3 is another structural representation of the present utility model.
The specific embodiment
The LED light fixture with excellent heat dispersion performance as shown in Figure 1 mainly comprises lamp holder 1 and heat radiation power pack 2 two parts, links to each other by two joint pins 3 between them.
Lamp holder has disc lamp holder radiator, and the central authorities of lamp holder radiator have the led chip container cavity, is packaged with led chip in the container cavity, is coated with lens 5 on the container cavity.The lamp holder radiator comprises a lot of strip fins from the outside radial extension of disc centre.These strip fins are divided into main rectangular fin 11 and the auxiliary rectangular fin between main rectangular fin 12 that is cross distribution, main rectangular fin is thicker, the supporting frame effect that it is main, main rectangular fin are positioned at inboard root and have installing hole, in order to connect pressure ring 6 lens are fixed on the lamp holder radiator.
Further, in order to strengthen radiating effect, can make each strip fin at the certain distance bifurcated, be that cooling surface area is bigger, and along with radius increases, bifurcated can not cause between the fin too tight again, still has rational space for circulation of air.
Power pack is covered with radiating fin outward too, in order to distribute the heat that driving power produces in the box.
Be connected with the U type fixed support of five sections flangings on the power pack, fit better with outer surface circular drives power supply device, setting angle can be regulated arbitrarily between 0--180 °.
Should be pointed out that present embodiment just lists expressivity principle of the present utility model and effect are described, but not be used to limit the utility model.Any personnel that are familiar with this technology all can make amendment to the foregoing description under spirit of the present utility model and scope.Therefore, rights protection scope of the present utility model should be listed as claims.
