A kind of knob energy-saving LED Down lamp
Technical field
This utility model relates to LED field, is specifically related to a kind of knob energy-saving LED Down lamp.
Background technology
Down lamp (downlight) is typically mounted on the periphery ceiling of bedroom, parlor, toilet. This hidden the putting property light fixture being flush-mounted within ceiling, all light all project downwards, belong to direct luminous intensity distribution. With different reflectors, eyeglass, shutter, bulb, different light effects can be obtained. Down lamp prevents take up space, can increase the soft atmosphere in space, if it is desired to build warm sensation, can try to install many Down lamps, alleviate space constriction. Along with the increase of range of application, the self-powered version of Down lamp is also becoming increasingly popular, but, the energy-conservation and flying power of Down lamp becomes the Radix Clematidis Clarkeanae of this kind of Down lamp.
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, a kind of simple in construction is provided, a kind of knob energy-saving LED Down lamp reasonable in design, easy to use, it adopts the setting at upper lower clapboard Yu spring, the break-make controlling LED can be rotated by light cover, and it has easy to use, simple to operate, simple in construction, the feature such as with low cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of knob energy-saving LED Down lamp described in the utility model, including lamp cylinder, lampshade and light cover, described light cover adopts with lamp cylinder threadeds, it is provided with lower clapboard and upper spacer in described lamp cylinder, it is provided with spring between described lower clapboard and upper spacer, described lower clapboard lower end is provided with power supply, described power supply lower end is connected with light cover, described lower clapboard is provided with lower joint pin, described lower joint pin is connected through lower clapboard with power supply, described upper spacer lower end is provided with upper joint pin, described upper joint pin is corresponding with lower joint pin, and at a distance of 5mm, upper spacer upper end is provided with LED and controls block, it is provided with lamp plate between described lampshade and lamp cylinder, described lamp plate surface configuration has lamp bead.
Described lampshade upper end is provided with lens.
Described power supply lower end is provided with protective block, and described protective block glue is solid on light cover.
After adopting said structure, this utility model has the beneficial effect that this utility model, and it adopts the setting at upper lower clapboard Yu spring, it is possible to rotated the break-make controlling LED by light cover; The self-recovery power of spring when off-position, can automatically spring open upper spacer and lower clapboard simultaneously, it is prevented that the connection between upper joint pin and lower joint pin; And it has easy to use, simple to operate, simple in construction, the feature such as with low cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As shown in Figure 1, a kind of knob energy-saving LED Down lamp described in the utility model, including lamp cylinder 1, lampshade 2 and light cover 3, described light cover 3 adopts screw thread 14 to be connected with lamp cylinder 1, lower clapboard 5 and upper spacer 6 it is provided with in described lamp cylinder 1, it is provided with spring 7 between described lower clapboard 5 and upper spacer 6, described lower clapboard 5 lower end is provided with power supply 4, described power supply 4 lower end is connected with light cover 3, described lower clapboard 5 is provided with lower joint pin 8, described lower joint pin 8 is connected through lower clapboard 5 with power supply 4, described upper spacer 6 lower end is provided with upper joint pin 9, described upper joint pin 9 is corresponding with lower joint pin 8, and at a distance of 5mm, upper spacer 6 upper end is provided with LED and controls block 10, it is provided with lamp plate 11 between described lampshade 2 and lamp cylinder 1, described lamp plate 11 surface configuration has lamp bead 12.
Described lampshade 2 upper end is provided with lens 13.
Described power supply 4 lower end is provided with protective block 15, and described protective block 15 glue is solid on light cover 3.
Its employing of this utility model is in the setting of upper lower clapboard Yu spring, it is possible to rotated the break-make controlling LED by light cover; The self-recovery power of spring when off-position, can automatically spring open upper spacer and lower clapboard simultaneously, it is prevented that the connection between upper joint pin and lower joint pin; Power supply places an order and arranges protective block, described protective block is fixed on light cover, and the setting of protective block is prevented from rotating the light cover damage to power supply during light cover, by increasing capacitance it is possible to increase the service life of its power supply, lamp plate and lamp bead can be played a protective role by the lens that lampshade upper end is arranged, and are also convenient for cleaning dust simultaneously; And it has easy to use, simple to operate, simple in construction, the feature such as with low cost.
The above is only better embodiment of the present utility model, therefore all equivalences done according to the structure described in this utility model patent claim, feature and principle change or modify, and are all included in this utility model patent claim.
