Description
Technical field
The utility model belongs to field of light fittings, particularly relates to the wide light-distribution LED Down lamp of a kind of small size.
Background technology
LED is a kind of semiconductor solid-state luminescent device; Have that light efficiency height, volume are little, firm in structure, life-span length, environmental protection (not containing hazardous substance), safety advantages such as (cold light sources), be the light source of new generation of conventional light source such as replace incandescent, Halogen lamp LED and fluorescent lamp.
The LED light fixture need install special heat abstractor additional because its particularity, and what this made the LED fitting structure is designed with supplementary biography system light fixture.Existing LED Down lamp, lamp body generally adopts aluminium die casting or extrusion process manufacturing, by two parts up and down dull and stereotyped lampshade is fitted together.Or adopt integral type aluminium die casting structure, and the injection moulding lampshade snaps in the lamp body breach, and this kind structure stays the breach of installation in the lamp body appearance.Above structure is all too complicated, needs at least two moulds could accomplish the installation of lampshade, and the latter can only adopt the lampshade of plastic material and can not adopt glass, has limited the application of some aspect.The narrow luminous intensity distribution scheme of the most employings of undersized LED Down lamp promptly uses the mode of lens to come optically focused at the light source place, such mode light efficiency is low, and light loss is big, has limited the application of its some aspect.
Summary of the invention
The utility model purpose be the defective to prior art provide a kind of heat radiation well, simple installation, the wide light-distribution LED Down lamp of handsome in appearance, adaptable small size.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
The wide light-distribution LED Down lamp of a kind of small size comprises heat radiation lamp body, light source board, jump ring mount pad and jump ring, and it is characterized in that: said LED Down lamp also comprises bottom reflection paper, offside reflection paper, diffuser plate, surperficial retainer ring; Said heat radiation lamp body bottom is provided with bottom stage; Light source board is placed on the said bottom stage; Said bottom reflection paper covers on the light source board; Offside reflection paper is fitted on the conical surface of thermal louver side, and said heat radiation lamp body oral area is provided with surface step, and said diffuser plate is fixed on the said surface step through said surperficial retainer ring.
Said surperficial retainer ring is provided with step; Said step side height is consistent with diffuser plate, and diameter is more bigger than diffuser plate, makes diffuser plate be placed in one just; Form a semi-enclosed cylindrical space with the step of heat radiation on the lamp body, from axially with radially diffuser plate is fixed.
Said jump ring mount pad is the outstanding of I shape breach, is arranged at heat radiation lamp body both sides and is connected as a single entity with the heat radiation lamp body.
The PMMA that said diffuser plate material is high mist degree, high transmission rate or PC or glass.
Light source board to the step that diffuser plate is installed that install said heat radiation lamp body bottom has certain distance, and the LED of different colours can be set on the said light source board.
Compared with prior art, the utlity model has following advantage: the utility model structure radiating effect is better, and simple installation, adaptability are strong, handsome in appearance.At first, step to the light fixture outer surface of the light source of adorning has certain distance, can sentence after to go out to form the such light efficiency of wide luminous intensity distribution by reflecting paper reflection higher so that light is sent out from light source board; And can the LED that uses different colours on the light source board make its in reflection cavity with regard to natural mixed light, make reflection cavity and mixed light chamber become one like this, for the high-color rendering of light fixture provides basic; Secondly, the diffuser plate of the light that is reflected by reflecting paper through high mist degree, high transmission rate can prevent dazzle (with using lens and comparing); And owing to be the integral type Design of Luminaires, lamp installation is after ceiling, and the heat of light fixture bottom can conduct to light fixture front surface face through the heat radiation lamp body, and the light fixture front surface right site space bigger, circulation of air is good, more helps the heat radiation of light fixture.Once more; Integrated radiating lamp body and surperficial retainer ring have reduced die casting quantity product cost, have reduced each accessory when diffuser plate is installed; Adopt heat radiation lamp body and surperficial retainer ring as device and decoration that diffuser plate is installed, played the effect of decorative appearance when realizing installation function.At last, the mounting spring place in the side, the heat radiation lamp body directly is connected with spring, has reduced related accessory.The utility model through glue can be simultaneously fixedly diffuser plate, two parts of surperficial retainer ring, required mould is few and simple, employed related accessory when having reduced mounting spring simultaneously is with low cost, simple installation.And with product of the same type to compare radiating effect better, light efficiency is higher, light loss is littler, is different from the narrow luminous intensity distribution of other products, it is little to be specially adapted to space length, face to be illuminated amasss big occasion.

The specific embodiment
Followingly the utility model is further described with reference to accompanying drawing:
With reference to Fig. 1, Fig. 2; The utility model is a kind of LED light fixture; Comprise heat radiation lamp body 1, surperficial retainer ring 2, be placed on the light source board 3 on heat radiation lamp body 1 bottom stage 11; Cover the bottom reflection paper 4 on the light source board 3, be fitted in the offside reflection paper 5 on the heat radiation lamp body 1 side conical surface, be placed on heat radiation lamp body 1 surface step 12 and by surperficial retainer ring 2 lockings its radially with the diffuser plate 6 of axial position, be installed in the spring 7 on the I shape breach jump ring mount pad 13 of heat radiation lamp body 1 side.Step 22 side height on the said surperficial retainer ring 2 are consistent with diffuser plate 6; Diameter is more bigger than diffuser plate 6; Make diffuser plate 6 be placed in one just, form a semi-enclosed cylindrical space with the step 12 of heat radiation on the lamp body 1, from axially with radially diffuser plate 6 is fixed (like Fig. 3); I shape breach jump ring mount pad 13 on the said heat radiation lamp body 1 is the structures that substitute the stamping parts of fixing spring on other similar Down lamps, and mounting spring has reduced the use and the installation steps of parts like this, more directly with succinct.
The light source board 3 that install said heat radiation lamp body 1 bottom to the step 12 that diffuser plate 6 is installed has certain distance, and the LED of different colours can be set on the said light source board.
Step to the light fixture outer surface of the light source of adorning has certain distance; Can be so that light goes out to form wide luminous intensity distribution via the reflecting paper reflection after sending from light source board; And can use the LED of different colours to make its natural mixed light in reflection cavity on the light source board; This makes the reflection cavity of light fixture and mixed light chamber unite two into one, for the high-color rendering of light fixture provides the basis; Secondly, the diffuser plate of the light that is reflected by reflecting paper through high mist degree, high transmission rate can prevent dazzle (with using lens and comparing).
The above embodiment that lifts is not only breaking away from the creation spirit scope of the utility model by the utility model conveniently to explain, is familiar with any simple covert and modification that the personage did of this technology, must be contained in the rights protection scope of the utility model.
