Abstract

The utility model discloses a light-emitting diode (LED) lamp with a heat dissipation function. The LED lamp comprises an outer shell cylinder (1), a reflector cover (2), a transmitting cover (3) and an LED light source (4), the reflector cover (2) is arranged in the outer shell cylinder (1), the LED light source (4) is fixed at the central position of the top face of the reflector cover (2), the transmitting cover (3) is fixedly arranged between the reflector cover (2) and the lower side edge of the outer shell cylinder (1), grooves (5) are evenly distributed in the wall face of the reflector cover (2), heat dissipation holes (6) are formed in the side wall faces of the grooves (5), and an inner cavity of the reflector cover (2) is communicated with an inner cavity of the outer shell cylinder (1) through the heat dissipation holes (6). The LED lamp has a good heat dissipation effect, and has the advantages of being long in service life and simple in structure.

Description

A kind of LED lamp with heat sinking function
Technical field
The utility model relates to a kind of LED lamp, particularly a kind of LED lamp with heat sinking function.
Background technology
Along with advantages such as development and the LED light fixture of LED technology have energy saving, the life-span is long and radiation is low, the application of LED lamp is more and more extensive.Although the LED light fixture has many good qualities, also there are a lot of weak points.
Traditional LED lamp caloric value is large, and all need in actual use to work long hours, its heat generally by diffuser with outside air, contact to conduct, distribute heat, for a long time in use procedure, causing the aging of diffuser, shortened the service life of light fixture.
The utility model content
The purpose of this utility model is, a kind of LED lamp with heat sinking function is provided, and it has good radiating effect, has advantages of long service life and simple in structure.
The technical solution of the utility model: a kind of LED lamp with heat sinking function, comprise outer thimble, reflection shield, diffuser and LED light source, reflection shield is located in outer thimble, LED light source is fixed on the center of reflection shield end face, diffuser is fixedly installed between the lower limb of reflection shield and outer thimble, the wall of reflection shield is provided with equally distributed groove, and the side wall surface of groove is provided with louvre, and the inner chamber of reflection shield is connected by louvre with the inner chamber of outer thimble.
In the aforesaid LED lamp with heat sinking function, described outer thimble is provided with radiating seat.
In the aforesaid LED lamp with heat sinking function, described radiating seat adopts aluminum to make.
In the aforesaid LED lamp with heat sinking function, described groove is the cone bucket shape.
In the aforesaid LED lamp with heat sinking function, described LED light source is comprised of LED circuit plate and LED lamp pearl.
Compared with prior art, the utility model arranges several grooves along the uniform setting in center on reflection shield, the louvre communicated with the shell tube inner chamber in the setting of groove side wall, make the heat in reflection shield be circulated to radiating seat shell chamber and to carry out the logical heat radiation of interior Xun circulation from louvre, alleviated pure structural limitations of dispelling the heat to the diffuser external world by reflection shield, the heat that can make LED lamp pearl produce when luminous transmits heat radiation in air, has guaranteed the lamp body illuminating effect and has extended its service life.In addition, also have advantages of simple in structure.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The outer thimble of being labeled as in accompanying drawing: 1-, 2-reflection shield, 3-diffuser, 4-LED light source, 5-groove, 6-louvre, 7-radiating seat.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment of the present utility model: as shown in Figure 1, a kind of LED lamp with heat sinking function, comprise outer thimble 1, reflection shield 2, diffuser 3 and LED light source 4, reflection shield 2 is located in outer thimble 1, LED light source 4 is fixed on the center of reflection shield 2 end faces, diffuser 3 is fixedly installed between the lower limb of reflection shield 2 and outer thimble 1, the wall of reflection shield 2 is provided with equally distributed groove 5, the side wall surface of groove 5 is provided with louvre 6, and the inner chamber of reflection shield 2 is connected by louvre 6 with the inner chamber of outer thimble 1.
Described outer thimble 1 is provided with radiating seat 7.Radiating seat 7 adopts aluminum to make.Groove 5 is the cone bucket shape.
Described LED light source 4 is comprised of LED circuit plate and LED lamp pearl.
Operation principle of the present utility model: after energising, the LED circuit plate is the power supply of LED lamp pearl, LED lamp pearl starts luminous, LED circuit plate and LED lamp pearl can produce a large amount of heats in work, the heat that they produce enters into the inner chamber of outer thimble 1 from the inner chamber of reflector 2 by the louvre 6 groove 5, heat passes to radiating seat 7 by the inner chamber of outer thimble 1, and radiating seat 7 rejects heat in air again.
