The invention discloses an operating lamp, and a light transmission cover and light spot regulation method of the operating lamp. The operating lamp comprises a light source, a housing, and a light transmission cover in front of the light source, wherein the light transmission cover includes a front cover and a back cover, at least one surface of the front cover is curved, at least one surface of the back cover is curved, the operating lamp further comprises a regulation device, and the relative position of the front and back covers is changed by the regulation device. The inventive operating lamp needs no control on the lamp base or internal illuminating devices, simplifies the internal structure, improves the reliability and can easily change the irradiation range.

The invention discloses a LED bulb which comprises a backseat. The upper part of the backseat is equipped with a lamp cover. The backseat and the lamp cover can be made of aluminum. An LED light source is positioned in the lamp cover. The lamp cover is equipped with a through hole. The LED light source is interpenetrated in the through hole and some part thereof is exposed at the outside of the lamp cover. The invention is characterized in that the lower part of the backseat is equipped with a bottom cover, a 1W 12V drive is positioned in the space formed between the backseat and the bottom cover, the drive is connected with the LED light source, the drive is connected with a G4 or MR16 lamp needle which is directly coordinated with a G4 or MR16 lamp socket, and one end of the light needle extends to the outside of the bottom cover. The LED bulb has the advantages of convenient assembly, small volume, good heat dissipation effect, large luminous efficiency angle (which can reach 180 degrees) and long service life.

The invention discloses a large-angle LED (light emitting diode) bulb lamp which comprises a lamp holder, a lamp bulb shell, a lamp post, a substrate and a plurality of LED light sources, wherein the lamp post is arranged in the middle of the top of the lamp holder; the lamp bulb shell covers the periphery of the lamp post; a light diffusion part is arranged on the top of the lamp post; the top surface of the light diffusion part is a plane and faces the top of the lamp bulb shell; the side surface of the light diffusion part faces the side wall and the bottom of the lamp bulb shell; the light diffusion part is made of a transparent or semi-transparent material; a light-transmittance scattering material is arranged on the light diffusion part; the LED light sources are arranged on the back of the substrate; the area of the substrate is smaller than that of the top surface of the light diffusion part; light emitted by the LED light sources on the back of the substrate irradiates toward the light diffusion part. The large-angle LED bulb lamp has the characteristics of large light distribution angle and good heat dissipation effect.

The present invention provides a multifunctional lighting lamp, which includes a housing, an LED lamp holder, a heat transfer plate, a reflective film and a bracket; the heat transfer plate is installed on one side of the housing; the bracket is installed on the other side of the housing; The LED lamp head is installed on the heat transfer plate; the reflective film is installed on the heat transfer plate. The invention is waterproof and dustproof, and also increases the luminous area.

A lamp assembly structure comprises a lamp holder and a power cord. The lamp assembly structure is characterized by further comprising an upper cover and turn fastener structures. The lamp holder is provided with an accommodating recess used for accommodating the upper cover; the upper cover is fastened within the accommodating recess through the turn fastener structures; the upper cover is provided with a through hole which deviates from the center of the upper cover; the power cord penetrates the through hole and extends out of the lamp holder; the upper cover can be turned to unlock from the accommodating recess by turning the power cord. With the upper cover and the turn fastener structures, the lamp assemble structure needs no screws for locking the power cord; the lamp assembly structure has the advantages of convenience in assembly, simple structure, convenience is disassembly and production automation.

The invention discloses a heat-dissipating lamp holder of an LED lamp. The heat-dissipating lamp holder comprises a lamp cylinder, wherein a tube body of which both ends are opened is served as the lamp cylinder; one end of the lamp cylinder is connected with a truncated conical lamp shell; a truncated conical mounting shell is arranged inside the lamp shell; the outer side surface of the mounting shell is connected with the lamp shell through a plurality of bolts; an LED light base is arranged inside the mounting shell; a disc glass sheet is arranged at the end, far away from the lamp cylinder, of the mounting shell; a reflective mirror is arranged on the inner side of the mounting shell; and a plurality of heat-dissipating fins are arranged on the outer side surface of the mounting shell at equal intervals. The heat-dissipating lamp holder has the advantages that air blown by fan blades passes through the heat-dissipating fins and takes away heat on the mounting shell, thereby achieving an LED lamp heat-dissipating effect; the heat-dissipating fins are good in heat-dissipating effect and high in quality, so that the service life of the LED lamp can be prolonged; meanwhile, the mounting shell and the lamp shell can be dismounted, so that the mounting shell and internal elements of the LED lamp can be independently replaced; and accordingly, the maintenance is convenient and the lighting effect is good.
