Abstract: A bulb holder structure includes a bulb holder, and a housing and a thermally conductive member fitting to the bulb holder. A protruding ring formed on an inner surface of the housing fits an annular base on a lower portion of the thermally conductive member. A plurality of protruding portions are peripherally distributed on an inner surface of the ring. An inner diameter defined by the protruding portions is smaller than an outer diameter of the base, that is, the ring forms an interference fit with the base of the thermally conductive member through the protruding portions, thereby effectively improving fit stability between the thermally conductive member and the housing, boosting yield, and ensuring excellent heat dissipation.

Abstract: A bulb lamp structure includes a base, a seat, a circuit board, and a bulb housing, and further includes a plurality of chips on which LEDs are mounted, a heat dissipater, and a double-sided board. The seat has a lower rim in which an air inlet opening is formed. The heat dissipater has a lower portion forming an annular hood that has an upper end on which a plurality of plate-like substrates is arranged to circumferentially delimit a chamber in communication with the air inlet opening of the seat. The chips are respectively mounted on outside surfaces of the substrates. The bulb housing has a top end having a central portion in which a ventilation hole is formed to correspond to an air outlet opening formed in a top of the heat dissipater. A large illumination angle can be effectively realized and automatic production can be facilitated.

Abstract: A double-sided LED light structure includes a casing that includes a base and a front chip arranged in the casing and electrically connected to the base and comprising an LED illuminant, wherein the casing has a rear end on which a rear chip that is electrically connected to the base and comprises an LED illuminant is mounted and a light-transmittable rear cover is set on and houses the rear chip. The front end of the light achieves concentrated illumination and the rear end achieves projection of supplemental light so that the LED light has a function of emitting light from two sides thereof to achieve a bettered three-dimensional illumination effect and also reduce the number of lights used.

Abstract: A focusing structure for an LED lamp is provided. LED chips are provided in a main body of the LED lamp, a front end of the main body 1 is provided with a lens assembly. At least one of the LED chips 2 is not located on the axis of the LED lamp, and at least two groups of lenses with different degrees are provided on the lens assembly, the location of each group of lenses corresponding to a corresponding LED chip on the same circumference, and the lens assembly is connected to the main body with structures capable of relatively rotating and snap-fitting. The LED lamp can achieve the focusing function by rotating the lenses assembly to make the lenses with different degrees correspond to the LED chips. This structure has no light loss and can achieve the focusing function of various focal distances.

Abstract: An LED lamp radiating structure includes a plastic shell and a metal part to serve as heat dissipation bodies. The metal part having a hollow structure is bonded with the plastic shell after the plastic shell is formed by injection molding. A baffle plate is formed on the metal part. An LED chip of the LED lamp is fixed below the baffle plate to contact with the metal part directly. The LED chip is completely contact with the metal part through the baffle plate, and therefore the heat dissipated from the LED chip is conducted to the plastic shell successfully, benefiting the heat dissipation of the LED chip.

Abstract: An adjusting structure for an LED lamp capable of adjusting the light beam includes a housing (1), an LED (2) fixed on the front end of the housing (1), a retractable adjusting seat (3) fitted on the outer side of the housing (1), and a convex lens (4) fixed on the outer end of the retractable adjusting seat (3). The convex lens (4) is positioned at the outer side of the LED (2). A rubber ring (5) is provided between the housing (1) and the retractable adjusting seat (3). Interference fits are formed between the rubber ring (5) and the housing (1) and the retractable adjusting seat (3) so as to generate damping between the retractable adjusting seat (3) and the rubber ring (5), thus a stepless adjustment is achieved.
