Abstract

The utility model relates to the technical field of illuminating lamps, in particular to an LED tube light. The LED tube light comprises a basin-shaped shell, an annular front cover, a chip integrated with a plurality of LED light sources, and a power source. A circular-platform-shaped spotlight cup is arranged in the shell, the chip is arranged at the small opening end of the spotlight cup and is fixedly connected with the bottom plate of the shell, a modified lens is fixedly arranged in the spotlight cup, and a light transmitting lens is arranged at the large opening end of the spotlight cup. The front cover is arranged in an opening of the shell in a buckling mode and fixing the spotlight cup and the light transmitting lens into the shell, and a wire of the power source penetrates through the bottom plate of the shell to be connected with the chip. According to the LED tube light, the angle of emergence of the LED light sources can be adjusted through the spherical modified lens, light is emitted out through the light transmitting lens after being refracted through the spotlight cup, and the light is made to achieve the even and soft illuminating effect. An integrated shell radiating structure can effectively lower the using temperature and prolong the service life of the LED chip, a spring support and the front cover in buckled connection with the spring support can be dismounted, maintained and cleaned conveniently and quickly.

Description

A kind of LED Down lamp

Technical field

The utility model relates to field of illumination lamp technology, particularly a kind of LED Down lamp.

Background technology

Down lamp is a kind of lighting that is embedded into light down-ejection type in ceiling.Its maximum feature is exactly to keep the entirety of building decoration unified and perfect, can not destroy because of the setting of light fixture the perfect unity of furred ceiling art.Down lamp does not take up space, and can increase the soft atmosphere in space, if want to build warm sensation, can try to install many Down lamps, also can alleviate space constriction.

Current Down lamp is generally divided into common Down lamp and LED Down lamp, relatively common Down lamp, LED Down lamp has better energy-conserving and environment-protective characteristic, and the light of LED Down lamp is better than common, can be used as the substitute of ordinary lamp and lantern, therefore there is better market application potential.LED Down lamp is generally arranged in ceiling, and LED can produce a large amount of heat energy when luminous, and its limited heat-dissipating space can cause the decline in service life; LED Down lamp needs ceiling and metope to carry out perforate when mounted, is fixed by screw, and not very convenient; And the rising angle of LED light source fixes, do not there is the divergent light source character of incandescent lamp, therefore need light-source angle to allocate, to improve the illuminating effect of LED Down lamp.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of compact conformation light soft, unpick and wash LED Down lamp easily.

For achieving the above object, the utility model is by the following technical solutions: a kind of LED Down lamp described in the utility model, comprise housing, the annular of peviform protecgulum, be integrated with the chip of some LED light sources, and power supply, in described housing, be provided with the prefocus cup of truncated cone-shaped, chip is located at the osculum end place of prefocus cup and is fixedly connected with the base plate of housing, is fixed with modification eyeglass in prefocus cup, and the big opening end of prefocus cup is provided with transmission lens; Described front cover buckle is located at the opening part of housing and prefocus cup and transmission lens is fixed in housing, and the wire of power supply is connected with chip through housing base plate.

Further, the outside of described housing is provided with some fin, and some fin arrange along the even interval of periphery of housing.

Further, described fin and the housing structure that is formed in one.

Further, the outer of described shell nozzle is provided with buckle, on housing, is evenly provided with some spring supports along periphery.

Further, have some jacks on described prefocus cup, the outer rim of modification eyeglass is provided with some buckleing a little of coordinating with jack.

The utility model beneficial effect is: the utility model is adjusted the angle of emergence of LED light source by the modification eyeglass of spheric, penetrates via seeing through transmission lens after prefocus cup refraction, makes light produce evenly soft illuminating effect; The housing radiator structure of integral type, can effectively reduce serviceability temperature, improves the service life of LED chip; The protecgulum fast and easy installing/dismounting of spring support and snapping, maintenance and clean.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

A kind of LED Down lamp described in the utility model, comprise housing 10, the annular of peviform protecgulum 20, be integrated with the chip 30 of some LED light sources, and power supply 40, the outer of described housing 10 openings is provided with the buckle 13 of ring-type, on the housing 10 of buckle 13 rear sides, be evenly provided with some spring supports 11 along periphery, the utility model when mounted, housing 10 is inserted installed surface, buckle 13 supports the outside of being located at installed surface, and spring support 11 is withheld the inboard at installed surface, and then housing 10 is fixed on installed surface.

In above-mentioned housing 10, be provided with the prefocus cup 31 of truncated cone-shaped, chip 30 is located at the osculum end place of prefocus cup 31 and is fixedly connected with the base plate of housing 10, and the material of the substrate of chip 30 and housing 10 is aluminum, and the heat that chip 30 produces is derived and distributed by housing 10; The outside of described housing 10 is provided with some fin 12, and some fin 12 arrange along the even interval of periphery of housing 10, fin 12 structure setting in the form of sheets, and then the outer surface that strengthens housing 10 is to improve heat dispersion; Fin 12 and housing 10 structure that is formed in one, can effectively improve heat conductivity and the production efficiency of housing 10.
