Abstract: An LED lamp device has a lamp seat, in which a lamp trough is formed by being recessed inwardly, and the inner edge surface of the lamp seat is formed as an arc surface. The front and rear parts in longitudinal direction of the lamp trough are also bent inwardly. Three rows of lamp set are arranged along the longitudinal sides in the lamp trough. These lamp sets have a plurality of LEDs as light-emitting elements. The lamp sets at left and right rows are inclined inwardly according to the curvature of the inner edge surface. In the meantime, the lamp sets at front and rear sides of one row are also inclined inwardly. Under this arrangement, the plural lamp sets not only can enhance the illumination of the lamp, but also can concentrate its light-emitting operation, for solving a shortcoming of light dispersal in most light sources.

Abstract: A heat dissipating LED signal lamp emitting structure includes an isothermal board, a light emitting unit on the isothermal board, a heat conducting cylinder connected to the bottom of the isothermal board, a heat dissipating body around the periphery of the heat conducting cylinder and comprised of heat sinks, a circular cover body above the isothermal board for covering the isothermal board, a reflecting groove at the center of the cover body for passing through the light emitting unit, and a transparent lid on the cover body for covering the light emitting unit. With the heat dissipating effect of the heat dissipating body, the operating heat produced by the light emitting unit can be dissipated to the outside. The invention not only uses a single light emitting unit as a signal lamp emitting source, but also enhances the light emitting efficiency and the life expectancy of the light emitting unit.

Abstract: In a quick assembling structure for LED lamp and heat dissipating module, the LED lamp set includes a casing and an LED module, and the casing has a containing hole, a stopping member protruded from an internal edge of the containing hole, a plurality of support stands extended outward from an external edge of the containing hole, and a latch portion formed on an internal side of the support stand. The LED module is contained in the containing hole of the casing and includes a base board and a plurality of LEDs fixed onto the bottom of the base board, and the heat dissipating module has an isothermal board installed on a side of the support stand of the casing, and a surface of the isothermal board is attached onto the base board of the LED module, and another surface is latched to a latch portion of the support stand. Such arrangement not only greatly reduces the labor cost for the assembling process, but also lowers the material cost for the screws.

Abstract: A heat conductive plate includes a hollow case and a plurality of grooves respectively formed on the inner top wall and the inner bottom wall of the case. In addition, a plurality of supporting members are positioned in the case by way of powder sintering, wherein each surface of the supporting members has a porous wick structure formed thereon. Thus, the case can be sustained by the supports with each wick structure firmly mounted in the grooves of the inner walls thereof. When performing heat transferring, the working fluid is heated to be formed as vapor by the electronic element mounted on the outer bottom surface so as to flow toward the inner top surface of the case. The working fluid is then cooled to be liquid again to be absorbed by the wick structures of the supporting members and be transported toward the inner bottom of the case.
