Abstract

The utility model relates to an LED high-efficiency and energy-saving down lamp, which belongs to the field of lamps and comprises a lamp casing, a circuit board and light sources, wherein the circuit board is mounted in the lamp casing, and the light sources are connected onto the circuit board. The LED high-efficiency and energy-saving down lamp is characterized in that radiating fins are connected onto the circuit board, radiating holes are arranged on the lamp casing, and the light sources are LED lamps. The LED high-efficiency and energy-saving down lamp is reasonable in structural design, wide in application range, high in lighting efficiency and energy conservation, long in service life and safe.

Description

The energy-efficient Down lamp of LED
Technical field
The utility model relates to the energy-efficient Down lamp of a kind of LED, belongs to field of light fittings.
Background technology
The light source of the common Down lamp of prior art is three kinds: 1, ordinary incandescent lamp, light efficiency are 121lm/W, and the life-span was less than 2000 hours; 2, spiral energy-saving lamp, light efficiency are 60lm/W, and the life-span was less than 8000 hours; 3, three-color fluorescent lamp, light efficiency are 96lm/W, and the life-span is 10000 hours.Have following shortcoming: 1, service life low, luminous efficiency and luminous flux are low, power consumption is big, and the mercury that contains hazardous substance; 2, luminously contain ultraviolet ray, solicit insects such as mosquito easily, human body is damaged; If 3 frequent startups, the starter process is long, burns out tungsten filament easily, and service life is low; 4, frangible fearness is fallen, transportation that can not effective and safe.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and provide that a kind of reasonable in design, high light efficiency height are energy-conservation, the energy-efficient Down lamp of LED of long service life and safety.
The technical scheme in the invention for solving the above technical problem is: the energy-efficient Down lamp of a kind of LED, comprise lamp housing, wiring board, light source, wiring board is installed in the lamp housing, light source connects in the circuit board, it is characterized in that: on described wiring board, be connected with fin, have louvre on described lamp housing, described light source is the LED lamp.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, have wide range of applications, high light efficiency height is energy-conservation, long service life and safety.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the utility model embodiment.
Fig. 2 is the structural representation of looking up of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1 and Fig. 2, the utility model embodiment comprises lamp housing 1, wiring board 2, light source 3, fin 4,
Lamp housing 1 has louvre 5.Wiring board 2 installs and fixes with light source 3 and is connected.Wiring board 2 and fin 4 are connected to each other the back gummed and are fixed in the lamp housing 1.
It is fixing that lamp housing 1 is inserted in fixed cover 6 usefulness bolts 7.
Wiring board 2 is worked in lamp housing 1 and is easily generated heat, and wiring board 2 heats are distributed, and the heat that distributes is discharged outside 1 lamp housing, guarantees the service life of wiring board 2.
Light source 3 is the LED lamp, and LED is a kind of semiconductor that electric energy can be converted into visible light, adopts electroluminescence, is characterized in that the life-span is long, light efficiency is high, radiationless, low-power consumption.The spectrum of LED almost all concentrates on the visible light section, and diameter is that 5 millimeters white light LEDs optical efficiency can surpass 150lm/W, and the life-span can be greater than 100000 hours, and is energy-efficient.
