Description
Technical field
The present invention relates to illumination or decorative lighting field of light fittings, be specifically related to light guide plate and LED lamp.
Background technology
Tengsten lamp is the incandescent lamp made using tungsten filament as filament, by filament electrified regulation to incandescent state, utilizes heat radiation to send the electric light source of visible ray.
Tengsten lamp has following shortcoming:
1, energising produces larger heat, and power consumption is high, and efficiency is low;
2, high-voltage product can only be made, so product safety performance is bad;
3, tungsten filament is oxidizable, so require inner sealing, the toughness of tungsten filament is not high, so product stability is bad;
4, for the product of that the inside filament shape complexity, the pseudo-classic incandescent lamp of such as Edison, doing manual work, it is careful to require, production efficiency is low;
5, shell can only make glass, frangible like this, and security is poor.
For traditional tengsten lamp Problems existing, prior art discloses the light fixture that a kind of LED substitutes tungsten filament, this light fixture is by forming tungsten filament together by LED wafer connection in series-parallel, and after energising, all LED wafer all can be luminous.Although this light fixture can substitute original tengsten lamp, expensive.And because the LED wafer adopted is more, voltage and current is still higher, and product safety performance is bad.
Summary of the invention
The present invention is directed to the problems referred to above, propose the simple light guide plate of a kind of structure and LED lamp.Solve prior art expensive, the problem that Product Safety is bad.
