A kind of LED jack-o-lantern

technical field

The utility model relates to an LED pumpkin lantern, which belongs to the technical field of semiconductor lighting.

Background technique

LED lights not only have high illumination intensity, small size, but also have the characteristics of long life, energy saving and environmental protection, and colorful colors. As an emerging industry combining semiconductor and traditional lighting industry, LED lighting has good development prospects.

LED is usually referred to as a cold light source, because its light-emitting principle is that electrons directly emit photons through recombination without the need for a heat process. Due to the existence of Joule heat, LEDs generate heat while emitting light, which is different from traditional lighting sources such as incandescent lamps. If the temperature is too high, its service life will be affected. Therefore, poor heat dissipation is a problem that cannot be ignored in LED lighting. If the heat dissipation is not timely, it will seriously affect the lighting effect and practical life of LED lights. On the basis of good heat dissipation, it is also necessary to ensure the rationality of the structure, high light extraction efficiency and uniformity of light.

At present, there are mainly the following problems in the heat dissipation design of LED lamps: the layout of the heat dissipation fins is unreasonable, the area of the heat dissipation fins is set arbitrarily, which affects the performance of the heat dissipation effect of the fins; the balance of heat transfer is ignored; the convection heat dissipation link is ignored, which is too Emphasis on the heat transfer link.

Utility model content

Aiming at the defects existing in the prior art, the utility model provides an LED pumpkin lamp, which optimizes the heat dissipation shell of the lamp, and has the characteristics of high heat dissipation efficiency, beautiful overall structure of the lamp, and light weight, and finally achieves the goal of reducing the overall temperature of the LED lamp. The purpose of upgrading is to improve the lighting effect and service life.

In order to achieve the above object, the utility model adopts the following technical solutions:

An LED jack-o-lantern, comprising a lamp holder, a cover, bolts, an aluminum substrate, a chip, screw holes, heat dissipation fins, a lamp cover, a lens, and a heat dissipation shell; the lamp holder is equipped with a driving power source, and is directly assembled with the cover through a slot; There are grooves on the heat dissipation shell, heat dissipation fins on the outer surface, and the interior of the heat dissipation shell is connected to the aluminum substrate; the lamp cover is directly assembled with the heat dissipation shell through the card slot, and assembled and fixed through screw holes, bolts and lamp caps; the chip Packaged on an aluminum substrate; the lens is located at the bottom of the lamp cover.

The LED jack-o-lantern adopts natural convection heat dissipation, and there are grooves on the heat dissipation shell, which is conducive to the ventilation and heat dissipation inside the lamp. Aesthetically pleasing and long-lasting LED jack-o-lantern.

Compared with the prior art, the utility model has the following characteristics:

High heat dissipation efficiency and long practical life: natural convection heat dissipation is adopted, the heat dissipation structure is reasonable, and the heat dissipation shell has grooves, which is convenient for ventilation and heat dissipation in the lamp, and the heat dissipation effect is good, which effectively solves the problem of serious light attenuation caused by excessive temperature of the LED chip , so that the life of the jack-o-lantern is greatly extended. Compared with other heat dissipation methods, such as liquid cooling heat dissipation and heat pipe heat dissipation, although the heat dissipation effect of the two is excellent, it undoubtedly increases the cost of the lamp, and it is unreasonable to use the above two heat dissipation methods in the structure of the pumpkin lantern. Therefore, the LED pumpkin The lamp has the above characteristics.

Relatively small mass: the structure of the LED jack-o-lantern is reasonable, and the cooling shell is optimized and has grooves, so the mass of the lamp is reduced, so that the lamp is not only small in mass but also has high heat dissipation efficiency.

Beautiful appearance design: from the large heat dissipation shell of the lamp to the small card slot design for assembly, this lamp reflects the innovation of design ideas. The streamlined cooling fins give people an aesthetic feeling. Moreover, all the various components of the lamp are placed inside the lamp, giving a sense of integrity.
