Description

Wireless light-dimming RGB intelligent bulb with good communication effect and capable of hiding antenna

Technical Field

The utility model relates to a combustion apparatus especially relates to a wireless RGB intelligent bulb of adjusting luminance that communication effect is good and can disappear antenna.

Background

Along with the improvement of living standard of people, intelligent application is more and more close to our life, and the Z _ Wave wireless intelligent cannon can be associated with other Z _ Wave equipment, such as a door magnet, and the functions of opening a door by opening a switch or reminding a mobile phone call are achieved. Or different colors may be modulated according to the atmosphere.

Because the Z _ Wave adopts a low power consumption mode, the working frequency band is 908.42MHz (American) to 868.42MHz (European), and compared with the 2.4G wireless communication distance, the communication distance is longer with the same power consumption. When little volume intelligence light big gun design, the antenna design has also become a drawback of product design, calculates antenna length according to the frequency: the antenna length of 300 kilometres (light speed)/900M (frequency)/4 =83mm, plus the metal shielding, actually debug the antenna and need increasing on the original computational formula, reach the impedance matching of 50 ohms of antenna, under the prerequisite that is interfered by the metal object, the antenna length is greater than more than 83mm at least, will occupy a considerable space.

The antenna in the existing wireless control LED bulb is arranged by being attached to a PCB (printed circuit board), the antenna is positioned inside a metal shell at the lower end of the bulb due to the arrangement (metal has a shielding effect on radio signals), the transmission of the radio signals is not facilitated very much according to an antenna efficiency radiation diagram, the antenna gain and the efficiency are lower, the transmission communication distance is poorer, and the normal communication cannot be realized if the area inside a house is large and the number of barriers is large when the indoor intelligent household is applied.

Then, some wireless control LEDs now adopt a layout of antennas perpendicular to the PCB to improve wireless signal transceiving capability. However, the vertical antenna layout can result in significant antenna shadows on the lamp, especially during dimming. The LED light source basically needs heat dissipation and is arranged on the aluminum substrate and connected with the heat dissipation shell into a whole, the shell is made of die-cast aluminum, the antenna needs to be arranged above the LED generally, and the light source projects shadows of the antenna from a plurality of angles in a projection mode. Other technical schemes increase LED light sources in the bulb, so that more light sources are provided to achieve a shadowless effect. In the dimming process, the more the LED light sources are, the more the shadow of the antenna is.

Further, the diffusion cover in the lamp is made of a PC material with the light transmittance of 95%. Under the less prerequisite of the luminance influence of 2% of loss, influence very little to experience the user, the projection of desalination antenna that can be better, whole luminance is even, in addition behind the PC outside diffusion dustcoat, the projection of antenna can't not be seen when luminance is very little, because the distance of antenna and metal casing is stretched far away, the efficiency of antenna is promoted, wireless remote control distance strengthens greatly, the projected problem of the fine solution antenna of while. Relative cost, only need increase several gross money costs on original LED intelligence ball big gun lamp, the promotion that product experience sense obviously obtained.

The utility model discloses a based on Z _ Wave wireless control mixing of colors intelligence light gun of adjusting luminance can pass through cell-phone APP control, also can pass through PC end control. And the remote wireless control can also be realized through a Z _ Wave gateway. Z-Wave is an emerging short-distance wireless technology based on the international ITU-T G.9959 standard, and has the characteristics of low power consumption, flexible networking and unified interface protocol.
