Description

Heat-conducting type LED module

Technical field

The utility model relates to and showing and lighting technical field, particularly belongs to a kind of LED luminescence unit with high efficiency and heat radiation performance.

Background technology

In daily life, LED enjoys consumer's favor with advantages such as its low-power consumption, life-span length and security performance are good, be widely used in fields such as lamp ornaments lighting, LED large screen display, traffic lights, household electrical appliances.For LED, because heating has consumed its gross energy of 70%, so radiating treatment is a vital problem; Traditional LED apparatus is integrated in LED on the substrate and constitutes, the shared heat abstractor of all LED, and radiating efficiency is low, is not easy to control and moulding and is restricted, thereby greatly reduce the applicability of LED apparatus.

The utility model content

The purpose of the utility model is to provide a kind of novel heat-conducting type LED module, to reach the radiating efficiency height, install and to make up flexibly, to prolong the LED purpose in service life.

The heat-conducting type LED module that the utility model provided; Comprise heat abstractor, LED luminescence chip and lens, it is characterized in that heat abstractor comprises thermal column, fin-shaped fin, circular heatsink; All be fixedly mounted on the back side of heat dissipation base; The front of heat dissipation base is equipped with chip pad, has the LED luminescence chip on the chip pad, and its outside is covered with lens; The heat abstractor top is equipped with kuppe, and the kuppe madial wall has the helical form raised line; Circular heatsink is looped around the periphery of thermal column layer by layer, penetrates up and down, has the inclination fin between the adjacent circular heatsink; It is radial around distribution that the fin-shaped fin with the thermal column is that central shaft is.

The heat-conducting type LED module that the utility model provided; In use, the heat that the work of LED luminescence chip is produced is absorbed by heat abstractor and distributes, particularly; Owing to have the inclination fin between the adjacent circular heatsink; The comprehensive function of helical form raised line on kuppe and the madial wall thereof in addition forms a kind of eddy airstream thereby hot-air is risen, and has accelerated the flowing velocity and the intensity of air-flow; Thereby can better dispel the heat, have good effect reasonable in design, that use is flexible, radiating efficiency is high.

Description of drawings

Accompanying drawing partly discloses the specific embodiment of the utility model, wherein,

Fig. 1, the structural profile sketch map of the utility model;

Fig. 2, heat abstractor of the utility model and heat dissipation base assembling sketch map.

The specific embodiment

The heat-conducting type LED module that the utility model provided comprises heat abstractor, kuppe 9, LED luminescence chip 6 and lens 7.As shown in Figure 2, heat abstractor comprises thermal column 1, fin-shaped fin 2, circular heatsink 3, all is fixedly mounted on the back side of heat dissipation base 4.Circular heatsink is looped around the periphery of thermal column layer by layer, has inclination fin 8 between the adjacent circular heatsink; It is radial around distribution that the fin-shaped fin with the thermal column is that central shaft is.

As shown in Figure 1, the front of heat dissipation base is equipped with chip pad 5, has LED luminescence chip 6 on the chip pad, and its outside is covered with lens 7.

The main feature of the utility model is that the heat abstractor top is equipped with kuppe 9, and as shown in Figure 1, the kuppe madial wall has helical form raised line 10.

In addition, as shown in Figure 1, above-mentioned circular heatsink is tapered, and promptly the internal diameter with one deck circular heatsink increases from top to bottom gradually, helps improving the flow velocity of rising radiating airflow, can improve radiating efficiency then.
