Abstract: A LED lamp and a light effect improving method thereof. A bulb shell (2) is covered on LED beads (3), and is mounted in a reflection cup (1). The bulb shell (2) is used for processing a primary optical process for the light emitted by the LED beads (3). The reflection cup (1) is used for processing a secondary optical process for the light which is subjected to the primary optical process performed by the bulb shell (2). By the functions such as refraction, scattering, diffusion and the like of the bulb shell (2), the primary emergent light emitted from the LED beads (3) is subject to the primary optical process such as mixing, scattering and so on, so as to realize the treatment effect that the light is emitted from the three-dimensional surface of the bulb shell (2). The reflection cup (1) performs the secondary optical process, so as to reflect the scattering light within a certain angle range.

Abstract: A warm white light LED chip with high brightness and high color rendering includes a white light part emitting a white light, a colored light part emitting a colored light with a wavelength of 580 nm-660 nm, an N electrode (8, 294, 394, 494) and a P electrode (7). Connected electrically with the N electrode (8, 294, 394, 494) and the P electrode (7) respectively, the warm white light LED chip directly emits warm white light with a color temperature of 2400K to 3500K and a color rendering index larger than 85. When the chip is lighted, the white light part emits the white light directly, or a blue light part stimulates fluorescent powder to form the white light, and the colored light part emits the colored light with the wavelength of 580 nm-660 nm to compensate the white light, thereby forming a low color temperature light source with high brightness and high color rendering.

Abstract: A condenser lens, lamp and camera applicable to an optical area are provided. The condenser lens is a physical glass lens and has an incident surface, an exit surface and a side surface arranged around a central axis of the condenser lens. The side surface is lattice-shaped. The condenser lens of the present invention adopts a glass material, which improves a light extraction efficiency of the lens and reduces a light energy loss. The lattice-shaped side surface of the lens reflects lights in different directions by multiple small-area lattice units instead of reflecting lights by a single curved surface. The reasonably-designed lattice structure enables each lattice unit reflecting lights in a predetermined direction, which may realize a uniform illumination at a small angle and is beneficial to spot-lighting. This condenser lens may be widely applied in all sorts of illuminating lamps or an illumination system of a camera.

Abstract: The present invention relates to illuminating techniques, and provides an LED lamp includes a lamp body, an LED lath inside the lamp body, plug modules disposed at both ends of the lamp body, and driving powers electrically connected the LED lath with the plug modules. The lamp body includes a heat dissipating cover and a light-transmissive cover which are connected with each other. The LED lath includes a lath and a plurality of LEDs disposed along the length direction of lath. The end LEDs disposed at the both ends of the lath have light-emitting surfaces which are inclined and irradiated to the driving power. For the LED lamp provided in the present invention, each end LED disposed at the end of the lath has an inclined light-emitting surface. Accordingly, the light emitting from the end LEDs at the both ends could irradiate to the driving powers at the both ends, and thus avoiding the shadow of LED lamp, and improving the emitting effect.
