Description

Radiating LED lamp

Technical field

The utility model relates to the technical field of LED lamp, especially a kind of radiating LED lamp that improves radiating efficiency.

Background technology

LED light fixture has that luminous efficiency is high, power saving and long feature of life-span, and therefore its application is more and more extensive.Because LED lamp is when luminous, the temperature of himself can constantly raise, and in lasting illumination work, if the heat that LED lamp produces can not exhale in time, will cause the damage of LED lamp, so the heat dissipation problem of LED lamp is the emphasis that the industry is paid close attention to always.LED lamp is also widely used in the place of the particular surroundings such as industrial and mineral.

Be similar to the larger lamp of this power of LED bulkhead lamp capable, existing cooling mechanism major part is that solid cylindrical heating column is set in the centre position of lampshade and power supply, on the circumferencial direction along heating column, be provided with the fin that several have smooth surface, there is following shortcoming in this cooling mechanism: volume is larger, because heating column is solid, cause the transmission speed of heat conduction slack-off, and the smooth surface of fin, make the degradation of heat radiation, thus the service life that can reduce whole bulkhead lamp capable.

Utility model content

The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of radiating LED lamp is provided.

The utility model solves the technical scheme that its technical problem adopts: a kind of radiating LED lamp, comprise lampshade, be arranged on lampshade inside light source, controlled light angle lens and be positioned at the radiating subassembly of lampshade top, lens are positioned at the top of lampshade, described radiating subassembly forms by conducting strip, the heat sink of light source being installed and being fixed on the fin that several longitudinal separations on heat sink arrange, in the both side surface of fin, all offer horizontal corrugated tooth, light source is positioned at the cavity of lens and conducting strip formation.

Described light source has substrate, is arranged on illuminator and conversion film on substrate, and luminous body position is between substrate and conversion film.

Described lens are convex lens.

Described fin reduces tapered by bottom to top width gradually.

Described heat sink and fin are one-body molded.

The beneficial effects of the utility model are: the utility model is simple in structure, easy to operate, fin has horizontal corrugated tooth, has increased LED lamp and has obtained area of dissipation, and the fin of taper, accelerate the radiating rate of fin, can be applicable to high-power LED lamp, small volume, heat dispersion is stable, improve operating efficiency, directed and concentrated illumination, applied widely.

In figure: 1. lampshade, 2. light source, 3. lens, 4. radiating subassembly, 41. conducting strips, 42. heat sinks, 43. fin, 431. teeth.

The specific embodiment

By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.

As Fig. 1, radiating LED lamp shown in Fig. 2 and Fig. 3, comprise lampshade 1, be arranged on the light source 2 of lampshade 1 inside, the lens 3 of controlled light angle and the radiating subassembly 4 that is positioned at lampshade 1 top, lens 3 be positioned at the top of lampshade 1 and with lampshade 1 phase clamping, radiating subassembly 4 is by the conducting strip 41 that light source 2 is installed, heat sink 42 forms with the fin 43 that several longitudinal separations that are fixed on heat sink 42 are arranged, between fin 43, leave space, form heat dissipation channel, spacing between fin 43 equates, in the both side surface of fin 43, all offer horizontal corrugated tooth 431, light source 2 is positioned at the cavity that lens 3 and conducting strip 41 form.

Lens 3 are convex lens, angle, the orientation of can controlled light penetrating, and the concentrated angle of illumination is 5-10 °, also can select lens according to actual light conditions, makes it reach needed lighting angle.

Light source 2 adopts COB chip, there is substrate, be arranged on illuminator and conversion film on substrate, luminous body position is between substrate and conversion film, luminous body position is between substrate and conversion film, illuminator is chip, the circuit of illuminator is all arranged on substrate, conversion film is mixed and is formed by glue and fluorescent material, can change the color of the light that illuminator sends, if need other color, can change the color of fluorescent material, make the color conversion of the light that illuminator sends become needed color, light source can, according to actual conditions, carry out quantitative increase and decrease.

In the both side surface of fin 43, all offer horizontal corrugated tooth 431, can increase the area of dissipation of fin, the height of fin is 40-80mm.

Fin 43 is reduced tapered gradually by bottom to top width, can accelerate the speed that fin 43 dispels the heat.

Heat sink 42 is one-body molded with fin 43, can make heat dispersion better; Heat sink 42 can be also split type with fin 43.

Below the course of work of the present utility model is further introduced:

After LED lamp is switched on power, illuminator is luminous, the temperature of illuminator increases generation heat, and at this moment, substrate absorbs heat, heat is conducted to conducting strip 31, heat is upwards passed to heat sink 42 and fin 43 by conducting strip 41, outwards disperses heat, simultaneously by fin 43, lens 3 are concentrated illumination to carry out orientation, increase the intensity of illumination.

Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
