Description
Technical Field
The invention relates to an LED light-emitting component, in particular to an LED light-emitting device which is formed by combining a plurality of standard components in different shapes, structures and purposes in a building block assembly mode.
Background
With the rapid development of science and technology, lighting devices mainly comprising LED light sources, which have the advantages of energy saving, environmental protection, high brightness, long service life and the like, are increasingly popular with consumers.
The internal structure of various LED light emitting devices in the prior art, such as a tube lamp, a bulb lamp or a street lamp, is basically a fixed and non-detachable and replaceable connection structure, and generally, these light emitting devices are basically composed of a power module, a lamp holder, a light source bracket and a lamp cover.
The shapes of the lamp holder and the lampshade are the shapes of traditional lamps, and once the lamp holder and the lampshade are shaped, the structure and the shape of the lamp holder and the lampshade can not be changed.
The light source is generally composed of an LED chip, a chip holder, a circuit board (including a rigid circuit board and a flexible circuit board) and a heat dissipation substrate (mostly an aluminum substrate), and the LED chip, the chip holder, the circuit board and the heat dissipation substrate are in a fixed connection structure that cannot be replaced or repaired, so that once a certain component is damaged, the light emitting device is basically scrapped. Moreover, the LED chip is limited in the way of increasing the brightness of the LED chip by increasing the working current in the mode of radiating the LED chip outwards through the chip support, and when the heat radiation is not smooth, the luminous efficiency of the LED chip is reduced, the service life of the LED chip is shortened, and therefore the power of the LED luminous device with the structure is limited. The reason is that: the luminous wavelength of the LED is changed to 0.2-0.3 nm/DEG C along with the temperature, the spectral width is increased along with the temperature change, and the color vividness is influenced. When forward current flows through a pn junction, the heating loss causes the junction area to generate temperature rise, the luminous intensity of the LED can be correspondingly reduced by about 1% when the temperature rises by 1 ℃ near the room temperature, and when the power density of the LED is increased, the junction temperature of an LED chip can be increased, so that the consequences of reduction of luminous efficiency, red shift of emergent light, reduction of service life and the like are directly caused.
The size and shape of the power module also vary with the structure, shape and placement of the corresponding light emitting device.
In addition, for the LED light emitting product industry, manufacturers, suppliers and product designers are in the battle, and a great amount of manpower, financial resources and time are invested to develop products of different specifications, types and standards, which cannot be complemented and replaced, so that not only is a great amount of useful resources wasted, but also some useful manpower and financial resources are consumed due to malignant competition, which is not favorable for the development of the country, industry, enterprise and individuals, and is not favorable for concentrating the vitality to carry out scientific and orderly deep exploration and research on the further development of the industry.
Therefore, in the LED light emitting product industry, how to adopt standardized basic components to enable consumers to quickly assemble light emitting products with different types, shapes and aesthetic feelings and different functions and quickly disassemble and replace the components according to personal preferences is a problem to be solved urgently.
