Technical field

The utility model relates to a kind of light fixture, relates to a kind of LED lamp affixed to the ceiling specifically.

Background technology

Along with providing of living standard, people also are more and more higher to the requirement of light fixture, except itself decorative effect requires, also will require the illuminating effect of light fixture, and itself the requirement of aspect of performance such as energy-conservation.Existing incandescent lamp and fluorescent lamp can not satisfy people's requirement gradually, in recent years, everybody needs have been catered in the appearance of various LED lamps, but the lighting effect of LED lamp and radiating effect can not reach coordination always, lighting effect good but because of its heat dissipation design is unreasonable, make the lost of life or result of use variation gradually.

It is the patent of 201011429Y that Patent Office of the People's Republic of China has announced notification number on January 23rd, 2008, and name is called: a kind of lamp affixed to the ceiling, this device comprise housing and be arranged on that suction in the housing is taken over a business, ballast, lamp holder and fluorescent tube; Fluorescent tube is provided with many, is arranged above and below and arranged in a crossed manner mutually, and the housing bottom is provided with sand surface glass plate; The staggered light in energising back goes out ornamental enhancing greatly when illumination is provided from following sand ground roll wave plate transmission.But because its use is fluorescent lamp, the life-span of use relatively weak point need regularly change fluorescent tube, secondly be stability, long back lighting effect service time variation gradually.

Summary of the invention

The utility model has mainly solved: the radiation response of traditional lighting lamp short problem in relatively poor and service life provides that lighting effect is good, long service life, a kind of LED lamp affixed to the ceiling that water resistance is good.

The technical solution adopted in the utility model is: a kind of LED lamp affixed to the ceiling, and it comprises pedestal, aluminium base, several LED lamp sources, constant-current source wiring board, reflecting shade body and transparent cover plate; Described pedestal is the cuboid with gradient, the upper end cross section of pedestal is less than the lower end cross section, the pedestal upper end has accommodation space, be provided with the step of placing aluminium base around the accommodation space, the both sides of accommodation space are provided with 2 semicircle steps that are used for fixing the constant-current source wiring board, and semicircle step upper end is provided with the installing hole of fixing constant-current source wiring board and is positioned under the above-mentioned step; The cylinder of a hollow is fixed at the accommodation space middle part, and the upper surface of cylinder flushes with step, and the pedestal lower surface has the entrance hole that communicates with the hollow space of described cylinder; All have the installing hole that cooperatively interacts on aluminium base, reflecting shade body, the step; Be fixed with several LED lamp source(-)holders on the described aluminium base; Described transparent cover plate matches with accommodation space, and is fixed on the upper surface of pedestal.

Power line passes entrance hole, introduces in the accommodation space of pedestal from the hollow space of cylinder, and be connected with the constant-current source wiring board, the constant-current source wiring board is connected with rear connection place of aluminium base, the constant-current source wiring board is placed on the semicircle step and fixes, then aluminium base is placed on the step of accommodation space, and be placed on the corresponding LED lamp source(-)holder LED lamp source also fixing, then reflecting shade body is placed on the aluminium base, and by screw reflecting shade body, aluminium base are fixed on the step, transparent cover plate and fixing at last closes on the pedestal upper surface.By the use of a plurality of LED lamp sources and reflecting shade body, the different arrangement modes in LED lamp source can form different light source effects as required, secondly are the uses of aluminium base, can improve the radiating effect of LED lamp.

Preferably, why pedestal is designed to have the cuboid of gradient, the one, for attractive in appearance, the 2nd, for the ceiling convenient fixing, the 3rd, be convenient to depanning.

Preferably, described reflecting shade body is provided with the reflection shield that matches with LED lamp source, and described reflection shield is tapered.

Reflection shield carries out reflective separately to each LED lamp source, increase whole light source effect.

Preferably, also be provided with packing ring between described pedestal upper surface and the transparent cover plate.The sealing of transparent cover plate can be provided by increasing packing ring, certain waterproof effect can be played simultaneously.

Preferably, described inclination range is: 3～5 degree.

The beneficial effect that the utility model is obtained is: 1) by using aluminium base, improved whole radiating effect, therefore prolonged service life; 2) a plurality of LED lamp source uses have increased lighting effect, and by changing the illumination mode that aluminium base changes LED lamp source; 3) use of reflecting shade body has strengthened the radiation response of each LED lamp source.
