Light-emitting device

The present invention relates to a light-emitting device, in particular to a light-emitting device capable of removing a light shield and replacing or adjusting an LED (Light-emitting diode).

With the advancement of technology, LED (Light Emitting Diode) has many advantages such as low power consumption, small size, long life and low temperature, etc., especially the advantages of energy saving, so that LEDs are widely used.

Traditional incandescent bulbs have been replaced by other lamps due to their high power consumption and high temperature. LEDs have become the mainstream of a new generation of lighting and are widely used in various lighting lamps. Efforts to develop a new lighting source.

At present, the design of the LED lamp is closed, and the LED lamp pellets are sealed in the light shield. Therefore, when the LED is damaged, the LED lamp will be discarded, resulting in waste of other available materials and increased cost.

Therefore, although the current LED lamps can meet the needs of general users and use a more energy-saving way to illuminate, the LED lamps must be discarded as a whole group if they are damaged or attenuated, which cannot exert the maximum effect, and there is still room for improvement.

In addition, LED lamps with adjustable brightness and color temperature are also introduced in the market. The biggest problem of this type of lamps is that the circuit for scheduling the luminosity is complicated and the control circuit must be additionally configured. Among them, the adjustment must be set on the lamp switch. Optical circuit, additional control circuit configuration in the wall, this method increases wiring difficulty and safety concerns.

Although some companies have proposed to control with a wireless remote control, this method can indeed achieve the purpose of reducing wiring, but additional wireless transmitting devices are needed, and the lamp itself must have a wireless receiving circuit, which leads to the high price of the lamp and the inconvenience of use. .

It should be limited to the example of this preferred embodiment.

In the second preferred embodiment, because the first assembly 312 can only be combined with the third assembly 322, the second assembly 313 can only be combined with the fourth assembly 323, so the first electrode 314 is only electrically connected to the third electrode 325 and not to the fourth electrode 326, and the second electrode 315 is only electrically connected to the fourth electrode 326 and not to the third electrode 325.

It can be seen from the above description that a light emitting device 3 of the present invention does have the following effects:

1. Simply change the luminosity: The substrate 311 is provided with a plurality of first assemblies 312 and a plurality of second assemblies 313, and different numbers of seat bodies 321 can be arranged on the substrate 311. The smaller the number of seat bodies 321, the weaker the luminous intensity. The greater the number of bodies 321, the stronger the luminous intensity.

2. The mask 327 can be removed: The photomask 327 can be detachably combined with the top wall 333. Unlike the earlier sealed photomask 327, the light-emitting module 324 can be clearly seen in the light-emitting device 3 of the present invention.

3. Reduce costs: As described above, because the photomask 327 can be separated from the top wall 333, the damaged or attenuated light emitting module 324 can be replaced, so that the undamaged power supply module 316 can continue to be used, effectively reducing the cost.

In summary, in the present invention, the base 321 is modularized and designed into a structure similar to a combination of building blocks. Through the combination of the third assembly 322 and the fourth assembly 323 with the substrate 311, not only the luminous intensity can be adjusted Therefore, the damaged or attenuated light-emitting module 324 can be replaced to avoid discarding the undamaged power module 316, so the purpose of the invention can be achieved.

However, the above are only two preferred embodiments of the present invention, and should not be used to limit the scope of implementation of the present invention, that is, simple equivalent changes and changes made in accordance with the scope of the patent application and the description of the invention Modifications are still within the scope of the patent of the present invention.
