Abstract

The utility model discloses a vane type self-luminous piece, which comprises a plurality of vanes (1) distributed independently. The vanes adopt the layering structure, a long afterglow material (2) is wrapped on a base layer of each vane in overlapping mode, and the vanes are connected into a whole through a rotating shaft (3) at intervals. The vane type self-luminous piece is used on a light-emitting diode (LED) lighting device, is capable of improving heat dissipation performance of a lighting device and can reduce flickering of lamps in work by rotating.

Description

Vane type self-luminous part

Technical field

The utility model relates to field of light fittings, particularly a kind of vane type self-luminous part that is used for the LED illuminating lamp.

Background technology

LED (light emitting diode) compares than incandescent lamp, electricity-saving lamp, has advantages such as energy-conservation, durable, pollution-free, is regarded as lighting system of future generation the most likely; Caused widely and paid attention to, because light emitting diode has unidirectional conduction, in order to remain on the stabilized illumination in the illumination application; Present way is to adopt direct current to drive, yet no matter be family, industry and commerce or public electricity-using at present, the mode with alternating current provides mostly; Must in light fixture, attach rectifier transformer for this reason and carry out the ac/dc conversion, this mode can be brought extra power consumption, and can reduce the product bulk life time; Answer this, Chinese patent document CN101208813B discloses a kind of " light-emitting device that is used for AC power operation ", and this device comprises LED wafer; This LED wafer has the luminescence unit that is connected in series of array, and the switching blocks that is connected respectively to the node between these luminescence units, wherein when this array is connected to ac voltage power supply and is driven by this ac voltage power supply; Open and close these luminescence units successively by these switching blocks, this light-emitting device can in turn be opened these arrays under AC power, then according to these arrays of opposite orderly close-down; Thereby can lower scintillation effect; And can increase fluorescent lifetime, still, this scenario-frame is complicated, high to the requirement of manufacturing process; Simultaneously; LED lamp heat in the course of the work is bigger to the harm of device, especially for high-power, highdensity application, relies on thermal-radiating traditional method can not satisfy radiating requirements.

The utility model content

The purpose of the utility model provides a kind of vane type self-luminous part, uses on the LED lighting device, not only can strengthen the thermal diffusivity of lighting device, and the flicker when reducing light fixture work through energy of rotation.

The utility model adopts following technical scheme to realize: vane type self-luminous part; This self-luminous part comprises the blade of some separations; Said blade adopts layer structure, and superimposition has the long after glow luminous material layer in blade basic unit, and each blade is evenly spaced to link into an integrated entity through rotating shaft.

The further technical scheme of the utility model is: this self-luminous part also is formed with radiator shutter.

This vane type self-luminous part can be used as secondary light source and uses, and uses on the LED lighting device of band rotational structure, not only can improve the thermal diffusivity of light fixture, and can reduce the flicker level of light fixture.

Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the protection domain of the utility model includes but are not limited to accompanying drawing and the disclosed content of embodiment.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to set forth.

Embodiment 1: shown in Fig. 1; This self-luminous part comprises the blade 1 of some separations; Said blade adopts layer structure; Superimposition has long after glow luminous material layer 2 in blade basic unit 5, and each blade is evenly spaced to link into an integrated entity through rotating shaft 3, and the operating position of this self-luminous part in the LED lighting device is as shown in Figure 3.

Embodiment 2: the difference of present embodiment and embodiment 1 only is have eight radiator shutters 4 evenly to be entrenched in the space between the blade 1.

Claims
