Abstract
The utility model relates to a waterproof down lamp heat radiation structure of LED, including establishing radiator (1) on the down lamp, radiator (1) on be equipped with a plurality of heat dissipation muscle (2), form between adjacent two heat dissipation muscle (2) radiating groove (3), radiating groove (3) lie in the last symmetric distribution of radiator (1) bottom surface, make a plurality of radiating grooves (3) pass radiator (1) both sides, and it is narrow that this radiating groove (3) are the mid portion position, and the partial recess of widening gradually in both ends makes the wide mouthful induced air mouth (31) of a plurality of recesses at the many angular distribution of radiator (1) bottom surface both sides department's formation. The utility model discloses can improve the radiating effect of radiator effectively, performance is better.
Description
Technical field
This utility model relates to a kind of lamp part, is specifically related to, in the heat spreader structures of a kind of LED down, belong to field of light fittings.
Background technology
The radiator of Down lamp is typically made up of section bar at present, a plurality of radiating ribs or thermal column are distributed on this section bar, the radiating ribs of this structured heat sink or thermal column typically use irregular or straight mode to be distributed, preferable wind guide and heat dispersion performance just can be played when therefore making radiator can only comply with wind direction, otherwise guide performance is poor, radiating effect is undesirable.
Utility model content
The purpose of this utility model is, has above-mentioned weak point to solve existing Down lamp radiator, it is provided that a kind of radiator with excellent heat dispersion performance.
The waterproof tubular lamp radiating structure of LED, including the radiator being located on Down lamp, described radiator is provided with some radiating ribs, radiating groove is formed between adjacent two radiating ribs, described radiating groove is positioned in radiator lower surface symmetrical, makes some radiating grooves through radiator both sides, and this radiating groove is that middle portion location is narrow, the groove that two end portions is gradually widened, makes multiple groove form the wide mouth air-vent of multi-angle distribution at radiator lower surface both sides.
Above-mentioned radiating groove is curved, makes some radiating grooves be positioned at radiator lower surface the most symmetrical.
The beneficial effects of the utility model:
1, radiating groove of the present utility model is distributed in the radiator lower surface on lamp cylinder, through radiator both sides, thus can make to make full use of free convection principle to dispel the heat, every radiating ribs of radiator leads directly to the most up and down, i.e. there is no any obstruct, the heat making LED is transmitted to radiating ribs, radiating ribs temperature rises, air themperature around radiating ribs the most then rises, air themperature once rises and will flow up, the air that the temperature of lower floor is relatively low supplements up, so circulation is the formation of convected air, thus the heat in radiating ribs is constantly taken away by the convected air of the radiating groove of the adjacent composition of radiating ribs, thus can be effectively improved the radiating effect of radiator, and then extend the useful life of lamp.
2, radiating groove of the present utility model is that mid portion is narrow, the groove that two end portions is gradually widened, and makes multiple groove form the wide mouth air-vent 31 of multi-angle distribution at radiator 1 lower surface lateral symmetry.Radiating groove is made to form multi-angle, multidirectional air guide hole on radiator, make radiating groove all can guide in radiating groove by air-vent by wind at multiple wind directions, thus improve the air mass flow in radiating groove, strengthen the radiating effect of radiator, in like manner, also Down lamp can be made when swinging arbitrarily angled, all can carry out good heat radiation by radiating groove.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 to Fig. 5 is radiating effect figure of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The waterproof tubular lamp radiating structure of LED as shown in Figure 1, including the radiator 1 being located at aluminum on Down lamp, described radiator 1 is provided with some radiating ribs 2, radiating groove 3 is formed between adjacent two radiating ribs 2, described radiating groove 3 is positioned in radiator 1 lower surface symmetrical, make some radiating grooves 3 through radiator 1 both sides, this radiating groove 3 is that middle portion location is narrower, the groove that two end portions is gradually widened, the i.e. groove groove width of radiating groove 3 middle is less, two end portions groove groove width incrementally increases, form wind guide tank, multiple groove is made to form the wide mouth air-vent 31 of multi-angle distribution at radiator 1 lower surface lateral symmetry.
Further, described radiating groove 3 is curved, makes some radiating grooves 3 be positioned at radiator 1 lower surface the most symmetrical.
When this utility model uses, as shown in Figures 2 to 5 (in figure: D is labeled as lamp luminescence direction, is labeled as air and enters that to flow to (described air is natural air), B be heat transmission gas direction of flow).When the radiating groove 3 of radiator flows to parallel with air (natural air) entrance, as shown in Figures 2 and 3, air (natural air) is kept straight on and is taken away the heat of radiating ribs 2 in flowing to radiating groove, reaches radiating effect；When the radiating groove 3 of radiator flows to not parallel with air entrance, time the most at an angle, as shown in Figure 4 and Figure 5, air, by taking away the heat of radiating ribs 2 in air (natural air) is imported radiating groove by the wide mouth air-vent 31 of multi-angle distribution on radiator 1, reaches radiating effect.
Claims (2)
- The waterproof tubular lamp radiating structure of 1.LED, including the radiator (1) being located on Down lamp, it is characterized in that: described radiator (1) is provided with some radiating ribs (2), radiating groove (3) is formed between two adjacent radiating ribs (2), described radiating groove (3) is positioned in radiator (1) lower surface symmetrical, make some radiating grooves (3) through radiator (1) both sides, this radiating groove (3) is that middle portion location is narrow, the groove that two end portions is gradually widened, multiple groove is made to form the wide mouth air-vent (31) of multi-angle distribution at radiator (1) lower surface both sides.
- The waterproof tubular lamp radiating structure of LED the most according to claim 1, is characterized in that: described radiating groove (3) is curved, makes some radiating grooves (3) be positioned at radiator (1) lower surface the most symmetrical.
