Abstract
The utility model discloses a high-efficient energy-saving light emitting diode (LED) tube lamp with good heat radiation performance, and the high-efficient energy-saving LED tube lamp comprises an aluminum alloy shell and an LED light source which is fixedly connected to the aluminum alloy shell, and the high-efficient energy-saving LED tube lamp also comprises a crystal oscillator which is arranged inside the lower end of the aluminum alloy shell, since the crystal oscillator has high heat conduction performance, the majority of the heat on the aluminum alloy shell can be transferred into the air when the crystal oscillator is electrified, so that when the LED tube lamp is in use and even when a large-power LED light source is used, the heat produced by the LED light source can be conducted onto the aluminum alloy shell, and the majority of the heat on the aluminum alloy shell can be transferred into the air through the crystal oscillator. The high-efficient energy-saving LED tube lamp has good heat radiation performance; and moreover, since the crystal oscillator has small size and light weight, the requirement for the supporting capacity of an installation field is not high, and the high-efficient energy-saving LED tube lamp can be widely utilized.
Description
Technical field
The utility model relates to a kind of lighting device, particularly relates to a kind of high-efficiency energy-saving LED Down lamp.
Background technology
Because LED Down lamp luminous efficiency is high, and is pollution-free, plurality of advantages such as long service life adopt the LED Down lamp to replace traditional halogen Down lamp more and more general as illumination in the market.But led light source can produce great amount of heat in luminous, if these heat energy are not derived, then the led light source light decay can be very big, even loses efficacy.High-efficiency energy-saving LED Down lamp in the market is to adopt aluminum alloy casing to give led light source heat conduction, and the size of aluminum alloy casing and weight also increase along with the increase of led light source power.The LED Down lamp generally is mounted in places such as ceiling, ceiling, because the enabling capabilities in these places is limited, so the volume and weight of light fixture is just had certain restriction.Therefore all be low power LED Down lamp in the market basically, require brightness high to some, the high-power illumination place that illumination is strong, existing LED Down lamp heat dispersion does not reach requirement, can not be suitable for.
The utility model content
The purpose of the utility model is to overcome the deficiency of present technology, provides a kind of heat dispersion good high-efficiency energy-saving LED Down lamp, and without large scale, big weight.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
The high-efficiency energy-saving LED Down lamp that a kind of heat dispersion is good, comprise an aluminum alloy casing, a led light source, a led light source cover, fixedly snap ring, a reflection shield, a glass cover and cap assemblies, connect support, also comprise a crystal oscillator; Said led light source is fixed in the aluminum alloy casing; The led light source cover places the led light source top, and also is fixed in aluminum alloy casing, and said fixedly snap ring places the aluminum alloy casing upper end; The reflection shield lower end places fixedly on the snap ring; Said glass cover is fixed in the cover assembly, and the combination of glass cover and cover assembly is arranged on the reflection shield, and said crystal oscillator is arranged in the aluminum alloy casing lower end; Said connection support lower end and aluminum alloy casing are affixed, and upper end and cover assembly are affixed.
Said cover assembly two ends down are extended with a boss, and boss is provided with downward opening holddown groove.
Said connection support comprises a diapire and the sidewall that up extends from the diapire two ends, and diapire places the aluminum alloy casing lower end, and the upper end is the holddown groove of inserting surface cap assemblies boss respectively.
Lower end, said two side and aluminum alloy casing are affixed.
The beneficial effect of the utility model is: because crystal oscillator has high thermal conductivity, when energising work, can the heat on most of aluminum alloy casing be exported in the air; Thereby the utility model LED Down lamp in use, even use the high-power LED light source, the heat that led light source produced is led on aluminum alloy casing; And crystal oscillator can export to the heat on most of aluminum alloy casing in the air; Thereby the utility model LED Down lamp perfect heat-dissipating, and because the crystal oscillator volume is very little, in light weight; Thereby the enabling capabilities to the installation site does not have high request, so can extensively apply to the place of needs.
Description of drawings
Fig. 1 is the utility model LED Down lamp overall schematic;
Fig. 2 is the utility model LED Down lamp exploded perspective view.
The specific embodiment
Below will specify the good high-efficiency energy-saving LED Down lamp of heat dispersion of the utility model with reference to accompanying drawing.
Like Fig. 1, shown in 2; The utility model LED Down lamp comprise an aluminum alloy casing 1, a led light source 2, a led light source cover 3, fixedly snap ring 4, a reflection shield 5, a glass cover 6 and a cap assemblies 7, connect support 8, comprise that also one has the crystal oscillator 9 of high thermal conductivity.
Said led light source 2 is fixed in the aluminum alloy casing 1; Led light source cover 3 places led light source 2 tops; And also be fixed in aluminum alloy casing 1, in the present embodiment, led light source 2 and led light source cover 3 are in the fastening mode of the affixed employing screw of aluminum alloy casing 1 (as among Fig. 2 10, shown in 11); In other embodiments, also can adopt other known technologies.
Said fixedly snap ring 4 places aluminum alloy casing 1 upper end, and reflection shield 5 lower ends place fixedly on the snap ring 4.
Said glass cover 6 is fixed in cover assembly 7, then the combination of glass cover 6 with cover assembly 7 is placed on the reflection shield 5.Said cover assembly 7 two ends down are extended with a boss 71, and boss 71 is provided with downward opening holddown groove 72.
Said crystal oscillator 9 is arranged in aluminum alloy casing 1 lower end.
Said connection support 8 lower ends and aluminum alloy casing 1 are affixed, and upper end and cover assembly 7 are affixed, thereby connect support 8 other each assemblies of LED Down lamp all are secured to together.Specifically; Said connection support 8 comprises a diapire 81 and the sidewall 82 that up extends from diapire 81 two ends, and diapire 81 places aluminum alloy casing 1 lower end, and 82 lower ends, two side are fixedly connected with aluminum alloy casing 1 through screw; In the holddown groove 72 of upper end difference inserting surface cap assemblies 7 boss 71; And sidewall 82 upper ends are fixedly connected with boss 71 through screw, through this connected mode, connection support 8 all is secured to other each assemblies of LED Down lamp together.
The lead of led light source 2 (figure does not show) is connected with the terminal and the driving power (figure does not show) of crystal oscillator 9, and in the present embodiment, this driving power is external driving power, in other embodiments, also can be arranged to be built in driving power.
Because crystal oscillator 9 has high thermal conductivity, when energising work, can the heat on most of aluminum alloy casing 1 be exported in the air; Thereby the utility model LED Down lamp in use, even use high-power LED light source 2, the heat that led light source 2 is produced is led on aluminum alloy casing 1; And crystal oscillator 9 can export to the heat on most of aluminum alloy casing 1 in the air; Thereby the utility model LED Down lamp perfect heat-dissipating, and because crystal oscillator 9 volumes are very little, in light weight; Thereby the enabling capabilities to the installation site does not have high request, so can extensively apply to the place of needs.
