Abstract: A LED light bulb structure has a base body, a control circuit board, a housing, at least a LED light source and a cover body. The base body is connected to the housing to form a containing space for disposing the control circuit board. The housing is disposed with a mounting portion that is inclined toward the housing to dispose the LED light source. Since the mounting potion is inclined, the illumination range of light beam of the LED light source is increased to provide wider illumination range without affecting the brightness of the LED light bulb structure, wherein the housing is integrally formed and disposed with a plurality of gutters at its outer surface to enhance heat dissipation effect, and integrated formation can also simplify the manufacture process and save the assembly time.

Abstract: A laterally installable rotating lamp includes a main body, a plurality of LED light sources, a transparent cover and an electric connector. The main body includes an air flow channel disposed on one side of the main body and the LED light sources disposed on the other side of the main body, and the transparent cover covers the LED light sources, and the electric connector is installed at an end of the main body through a connecting portion and electrically coupled to the LED light sources. The air flow channel is provided for quickly dissipating the heat produced by the LED light sources to prevent a light attenuation of the LED light sources caused by the thermal interference, and a reduced service life. In addition, the connecting portion can be rotated to adjust the illumination angle or the lamp.

Abstract: The present invention provides a lighting apparatus for nail beauty comprising a bottom plate having a shape non-restricted to any form and a housing having an arched main body attached to the bottom plate to form a space therebetween; characterized in that: a plurality of lighting modules are provided on a top and two lateral sides of the housing to form a ring array; the lighting modules comprise light sources and heat sinks; the lighting modules provided on the top of the housing are tilted slightly such that light emitted therefrom is shone toward the front end of the apparatus and toward the area opposite of the opening of the space between the housing and the bottom plate. Therefore, fewer light sources are required for uniform UV lighting on the nails and the reflection of UV light out to the external of the apparatus can be prevented for safer uses.

Abstract: An illumination lamp includes an electric connection portion, a heat dissipating casing, a printed circuit board, light emitting diodes and a transparent cover. The heat dissipating casing is installed onto the electric connection portion and includes abuse wall and a surrounding wall. The base wall has an arc camber protruded from the periphery of the base wall towards the center of the base wall and away from the electric connection portion. The surrounding wall is extended from the periphery of the base wall. The printed circuit board includes a center hole and a groove, and is attached onto the base wall. The light emitting diodes are installed separately on the printed circuit board. The transparent cover is covered onto a side of the heat dissipating casing. Since the light emitting diodes are installed along the arc camber, the illumination range is expanded, and the illumination uniformity is enhanced.
