Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0023] Such as figure 1 As shown, an LED wide-angle bulb lamp includes a lamp cap 5, a lamp holder arranged on the lamp holder 5, a radiator 4 arranged on the lamp holder, and a lamp body.
[0024] The radiator 4 is a hollow structure, with heat dissipation ribs around the outside, and a lamp body light-emitting driver for driving the bulb lamp inside the radiator. The driver is installed in the radiator, which can not only save space, but also make the bulb lamp smaller , and is conducive to the heat dissipation of the driver, the heat of the driver can be directly dissipated to the outside world through the radiator.
[0025] The lamp body includes a light-transmitting cover 1 and an LED light source assembly disposed inside the light-transmitting cover 1 . The transparent cover 1 is directly installed and fixed on the top of the radiator, and th...
