Abstract
The utility model discloses a heat radiator for a light emitting diode (LED) tube light, which comprises a hollow cylindrical tube body and heat radiating fins distributed around the tube body, the end surface of the heat radiator is in a sunflower shape, each heat radiating fin is in an S-shaped tuning fork shape, the end of each heat radiating fin is in a zigzag shape, and the inner wall of the tube body is in a corrugated shape. The heat radiator for the LED tube light has high heat radiating performance, light weight and low cost.
Description
Technical field
The utility model relates to the LED technical field, and especially the LED Down lamp is used radiator.
Background technology
LED is widely used on the lighting.The LED Down lamp is with the indoor universal lighting that is aided with application specific architecture behind the led light source array and forms.The technology trends of LED Down lamp is long-life, high light efficiency and a low cost of pursuing light fixture.The problem that LED self exists is, the light fixture light efficiency receives the influence of junction temperature of chip bigger, and higher junction temperature of chip will cause light efficiency to descend, and influence the service life of LED Down lamp.Therefore, the heat dissipation problem of solution LED Down lamp is most important for the performance that promotes the LED Down lamp.Along with improving constantly of led chip power output, existing LED Down lamp radiator heat-dissipation effect is still waiting further improvement.
Summary of the invention
The purpose of the utility model is to provide the LED Down lamp that a kind of heat dispersion is high, in light weight, cost is low to use radiator.
The purpose of the utility model realizes through following technical scheme: a kind of LED Down lamp is used radiator, comprises hollow circular cylinder and is distributed in cylindrical shell fin on every side, and it is flower-shaped that the radiator end face is the sun, the S-shaped tuning fork-like of said fin.
Further preferred as the utility model, said fin is not held the indention shape.
Further preferred as the utility model, said cylinder inboard wall undulate shape.
The LED Down lamp that the utility model provides is used radiator; The S-shaped shape of fin has increased the length of fin, and area of dissipation increases; Simultaneously fin is not held and be designed to zigzag fashion; Further increase area of dissipation, the inner face of the hollow cylinder in the middle of the radiator has been done waviness, can on the basis that keeps performance, reduce certain weight.
Description of drawings
Fig. 1 is that the utility model LED Down lamp is with radiator end face sketch map.
Fig. 2 is an A place partial enlarged drawing among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of LED Down lamp is used radiator, comprises hollow circular cylinder 1 and is distributed in cylindrical shell 1 fin 2 on every side, and it is flower-shaped that the radiator end face is the sun, fin 2 S-shaped tuning fork-likes, and the design of S shape has increased the length of fin 2.For further having increased area of dissipation, fin 2 do not held be designed to zigzag fashion, like Fig. 2.Cylindrical shell 1 inwall in the middle of the radiator is done waviness, alleviated the weight of radiator to a certain extent.
Claims (3)
1. a LED Down lamp is used radiator, comprises hollow circular cylinder and is distributed in cylindrical shell fin on every side, and it is flower-shaped that the radiator end face is the sun, it is characterized in that: the S-shaped tuning fork-like of said fin.
2. LED Down lamp according to claim 1 is used radiator, it is characterized in that: said fin is not held the indention shape.
3. LED Down lamp according to claim 1 is used radiator, it is characterized in that: said cylinder inboard wall undulate shape.
