Abstract
The utility model discloses an LED (Light-emitting Diode) direct type light, belonging to the technical field of illumination. The LED direct type light is composed of a light-transmitting cover, an aluminum shell, a PCB (Printed Circuit Board) with an LED light source, a mirror-surface reflecting cup, an LED driving power supply, a clamp spring, screws and nuts. The light-transmitting cover is directly arranged inside the aluminum shell, the PCB with the LED light source is fixed in the mirror-face reflecting cup through the screws, the mirror-face reflecting cup is fixed on the aluminum shell, and the LED driving power supply is fixed on the mirror-face reflecting cup through the screws. The mirror-face reflecting cup is smaller than 30mm in height and is 5 degrees in conicity. Because the mirror-face reflecting cup is smaller than 30mm in height and is 5 degrees in conicity, the luminous flux output by the LED light source is utilized to the maximal extent; and according to the utility model, by means of reducing the height of the mirror-face reflecting cup and removing a power supply fixing frame, the height of the entire light is reduced greatly and the LED direct type light is particularly suitable for being used in buildings in which a distance between a ceiling and a floor is short. In addition, the entire light is lighter in weight and safer to use.
Description
Technical field
The utility model belongs to lighting technical field, relates in particular to a kind of LED straight hair light Down lamp.
Background technology
At present, the reflector of the LED straight hair light Down lamp that on market, uses is generally highly all greater than 50mm, and the reflector tapering is also bigger, and the LED driving power is fixed on the power supply fixed mount, and the power supply fixed mount is fixed on the shell.The reflector height is big, and the tapering conference reduces the output light flux of led light source, and cost is also high; The LED driving power is fixed on the power supply fixed mount, and power supply is fixed on the shell again, has not only increased material cost and processing procedure cost, and has increased the whole height and the weight of light fixture together with high reflector.
Summary of the invention
The purpose of the utility model is to avoid the weak point of prior art, and a kind of high light efficiency is provided, and the whole light low-cost LED straight hair light Down lamp of lamp height low weight is installed simply.
The purpose of the utility model reaches through following measure, LED straight hair light Down lamp, and by diffuser, the aluminium shell, the pcb board of band led light source, the minute surface reflector, the LED driving power, jump ring, screw, nut is formed.Said diffuser is set directly in the aluminium shell, and the pcb board of band led light source is fixed in the minute surface reflector with screw, and said minute surface reflector is fixed on the aluminium shell, and the LED driving power is fixed on the minute surface reflector with screw.Said minute surface reflector height is less than 30mm, and tapering is 5 °.
The beneficial effect of the utility model is: 1, said minute surface reflector height is less than 30mm, and tapering is 5 °, has utilized the output light flux of led light source to greatest extent, has improved the light efficiency of whole lamp.
2, the utility model LED driving power directly is fixed on the minute surface reflector, and processing procedure is more oversimplified.
3, the utility model is through reducing the height of minute surface reflector, and cancellation power supply fixed mount significantly reduces whole lamp height, is highly suitable for ceiling and uses apart from short building apart from floor.And whole lamp weight is lighter, uses safer.
4, the cost that the utility model is lower more can make market approval LED light fixture.
Description of drawings
Fig. 1 is the installation diagram of the utility model;
Fig. 2 is the structural representation of the utility model;
Shown in the figure: 1, diffuser, 2, the aluminium shell, 3, pcb board, 4, the minute surface reflector, 5, the LED driving power, 6, jump ring, 7, screw, 8, nut.
The specific embodiment
Further the utility model is explained below in conjunction with the accompanying drawing and the specific embodiment;
Embodiment: as shown in Figure 1, the purpose of the utility model reaches through following measure, and LED straight hair light Down lamp is to comprise by diffuser 1 aluminium shell 2; The pcb board 3 of band led light source, minute surface reflector 4, LED driving power 5; Jump ring 6, screw 7, nut 8 is formed.Diffuser 1 is set directly in the aluminium shell 2, and the pcb board 3 usefulness screws of band led light source are fixed in the minute surface reflector 4, minute surface reflector 4 directly are fixed on the aluminium shell 2 again, and LED driving power 5 usefulness screws are fixed on the minute surface reflector 4.The utility model minute surface reflector 4 height are less than 30mm, and tapering is 5 °, has utilized the output light flux of led light source to greatest extent, has improved the light efficiency of whole lamp.The utility model LED driving power directly is fixed on the minute surface reflector, and processing procedure is more oversimplified.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change, conspicuous variation of being extended out thus or change still are among the protection domain of the utility model.
Claims (2)
1. LED straight hair light Down lamp, by diffuser, the aluminium shell, the pcb board of band led light source, the minute surface reflector, the LED driving power, jump ring, screw, nut is formed; Characteristic is that said diffuser is set directly in the aluminium shell, and the pcb board of band led light source is fixed in the minute surface reflector with screw, and said minute surface reflector is fixed on the aluminium shell, and the LED driving power is fixed on the minute surface reflector with screw.
